托福听力推断题型提升正确率答题思路实例讲解((集锦10篇))由网友“scaryamao”投稿提供,以下是©无忧考网为大家整理后的托福听力推断题型提升正确率答题思路实例讲解,希望对您有所帮助。
篇1:托福听力推断题型提升正确率答题思路实例讲解
最常见的,就是话说一半型推断:也就是往往原文的话不会说完,留下想(出)象(题)的空间,或者中间会缺少衔接的逻辑,需要自己推导。
比如说,听力里说了两句话:
1. 动物都是要喝水的
2. 所以人要喝水
问:What can be inferred from 刚刚这两句话里?
这中间其实就跨过去了一条逻辑。前后这两句话摆在一起,其实默认了一个逻辑:动物要喝水——(人属于一种动物)——所以人要喝水。
所以答案就是:人是一种动物。
推断题,往往就是这个套路,接下来让我们来看几个难题实例。
托福听力推断题难题实例精讲
托福官方模考套题40 Lecture 3 Q5:
What does the professor mean when he refers to biomass carbon as “current carbon”?
A. It is the fuel source most widely approved by environmentalists today.
B. It is part of a balanced system of carbon emission and absorption.
C. It is circulated throughout the oceans by the movement of ocean water.
D. It readily combines with other carbon molecules to produce long chains.
原文是这样的:
Biomass carbon is what we might call current carbon.It's always going in and out of the atmosphere. (第一层逻辑) So if we burn one of these fuels, we're putting its carbon into atmosphere. Right? (第二层逻辑)But in a balanced system, somewhere else in the world the same amount of carbon is going back.(第三层逻辑) It gets taken in by growing vegetation. So burning biomass fuel produces sort of not-so-bad carbon(第四层逻辑)
我们一起来分析一下,这段话里:
第一层逻辑:Biomass carbon=current carbon(先不要管这两个专业名词是什么意思,此处并不重要),并且在大气层里进进出出;
第二层逻辑:燃烧这些biomass的燃料,就会增加碳排放量;
第三层逻辑:但是在一个平衡的系统里,碳排放量会被吸收;
第四层逻辑:所以燃烧biomass产生的碳排放并不是很糟糕。
这几句话重点在第三、四层逻辑上,也就是:本来biomass燃料是会增加碳排放量的,但是在一个平衡的系统里,排放出去的碳会被吸收回去,所以这么看来biomass也不是很糟糕。
所以这几句话隐藏的一层逻辑关系是:我们默认biomass carbon是一个balanced 系统(所以情况才不会那么糟糕)
所以这道题选B。
托福官方模考套题43 Lecture 1 Q2
What does the professor imply when she explains why leaves are green?
A. She wants to correct a common misconception about the topic.
B. She thinks the students are probably already familiar with the material.
C. She believes the process is too complicated to discuss in depth.
D. She knows that students are often confused about the functions of chlorophyll.
原文是这样的:
before we discuss why leaves turn red, first, let's, urn, look, I know this is very old material, but just to play it safe, let's first go over why leaves are usually green. It's chlorophyll, right?
这段话明面上给出我们的信息:
“树叶为啥变红”这个问题是老生常谈 ;
教授是出于保险起见,现在要复习这个老生常谈的东西。
所以我们能推断的信息:教授默认这是大家本应知道的东西。
所以这道题选B。
篇2:托福听力推断题型提升正确率答题思路实例讲解
所以一般来说,推断题答案都会散布在文章中,不会直接提及,但一定能在文章中找到理论支撑。所以最常见的要用到因果逻辑、转折逻辑和一点点概括能力。
所以在听听力原文的时候,我们要关注:教授话说了一半没有继续说下去的时候,尤其是有明确转折, 但是又没有明说转折后面是啥的时候;或者是教授提到了两种相互关联的东西,却只明确解释了其中一方的时候。
托福听力中“研究、实验”的考点思路怎么解
在托福听力考试中,Lecture往往是同学们最大的痛。所谓的Lecture其实就是Professor上课内容的一个片段——涉及的学科往往分以下四类:
艺术
自然科学
生命科学
社会科学
从这四个分类我们可以看出Lecture具有极强的学术性,这也是为什么学生感到头疼的重大原因。不过,其实Lecture并没有大家想象的那么难,Lecture的整体结构和出题思路还是有很强的规律性的,今天Ted就主要和大家探讨一下关于Lecture(以及部分学术类Conversation)中出现研究、实验内容时常见的考点思路。
首先,我们先来看一组选自托福线上练习中涉及到研究、实验类的题目:
What surprising information did a recent experiment reveal about lesser spear-nosed bats?
The woman mentions a research study of milk packaging. What was thefinding of the study?
What was demonstrated by the study on perception that the professor mentions?
What does the professor say about the results of the brain research?
What is the significance of the evidence found on the ocean floor?
What did calcite deposits from Devils Hole reveal?
The professor discusses a study on the relationship between brain growth and play. What does that study conclude?
What did researchers conclude from their study of sauropods and gastroliths?
According to the professor, what were the results of Goeth's experiments with color?
What did researchers conclude after analyzing fossilized dinosaur bones found near nests?
According to the professor, what did researchers find at an archaeological site in Turkey?
What did researchers discover about the planet Gliese 581d when they reexamined it?
What did researchers observe in the study of fourteen-year-old children?
这些题目都是问到了关于Lecture中提及的experiment, research, study…
但从题干中的其他关键词:reveal, demonstrate, conclude, find, discover, observe, finding, result, evidence,我们还可以总结出,这些关于研究、实验类的题目问的都是研究者发现了什么,研究揭露、表明了什么,研究结论是什么。
所以总而言之,当Lecture中提及研究、实验时,我们需要听懂并记录的常见考点就是——研究的结论!
例如:
Yeah, and I read a study that showed how light can give milk a funny flavor and decrease its nutritional value.
Again, studies have shown that people will fill in information that they thought they perceived even when they didn't.
Gliese 581d had actually been discovered a couple of years earlier, and when its orbit was originally calculated it was thought to be too far away from its hosts star to be warm enough to support a liquid ocean, let alone, carbon-based life. But then its orbit was recalculated, and nowwe see that Gliese 581 D is within its host’s habitable zone.
为大家罗列一些听力中研究结论的常见信号词:
第一步:先听到professor提及“研究”
study,research,experiment,article,journal…
scientist,researcher,archaeologist,geologist,biologist…
科学家人名 e.g. Galileo
第二步:听到“结论”并记录
show,indicate,suggest,turn out…
find,discover,observe,we learnt,we see…
result,conclusion,finding,evidence…
in the end,finally,and get this…
接下来,我们再来看另外一组选自托福线上练习的有关研究、实验的题目:
The professor mentions experiments on the wind speed necessary to move rocks. What is the professor’s attitude toward the experiments?
What is the professor’s opinion about the conclusions of the recent study of the limestone formations in the Empty Quarter?
What is the professor’s opinion of a recent study of prairie dogs?
What is the professor's opinion about recent genetic studies relating to whale evolution?
The professor discusses research about the percentage of a chromosome’s DNA that contains genetic information. How did she feel about this research?
What is the professor's attitude toward the results from medical research on snake venom proteins?
What is the professor's attitude toward the study on pigeons and mirror self-recognition?
这些题目同样都是问到了关于Lecture中提及的experiment, research, study…但从题干中的其他关键词:professor’s opinion, professor’s attitude, how did she feel about… 我们还可以总结出,这些关于题目问的教授对于提及的研究的态度,且通常是对于研究结论给出的态度。
所以,这些态度的表达往往出现在老师提及研究,并将研究结论告知学生之后。
例如:
One team of scientists flooded an area of the desert with water, then try to establish how much wind force would be necessary to move the rocks. And get this, you need winds of at least five hundred miles an hour to move just the smallest rocks. And winds that strong have never been recorded. Ever! Not on this planet. So I think it’s safe to say that that issue’s been settled.
The DNA suggests that whales are descendants of the hippopotamus. Yes, the hippopotamus! Well, it came as a bit of a shock. I mean, that a four-legged land and river dweller could be the evolutionary source of a completely aquatic creature up to 25 times its size? Unfortunately, this revelation about the hippopotamus apparently contradicts the fossil record, which suggests that the hippopotamus is only a very distant relative of the whale, not an ancestor. And of course as I mentioned, that whales are descended not from hippos but from that distant wolf-like creatures. So we have contradictory evidence. And more research might just raise more questions and create more controversies. At any rate, we have a choice. We can believe the molecular data, the DNA, or we can believe the skeleton trail, but unfortunately, not both.
Well, not that we know of. There was a study using pigeons, where researchers attempted to reduce MSR to a matter of conditioning, that is, they claimed that the ability to recognize oneself in a mirror could be learned. So these researchers basically trained some pigeons to pass the mirror mark test. But two things are noteworthy here. One, no one’s ever replicated the study. But more importantly, it misses the point. The issue isn’t whether some behavior can be learned. It’s whether a species has developed this ability spontaneously.
常见态度信号词
第一人称:
I think,I believe,I mean,I hope,in my opinion…etc.
we’ll,we can,we are…etc.
转折词:
but,however,on the other hand…etc.
以上为Ted对Lecture中研究、实验相关题目出题思路的浅析,希望能够帮助到同学们。以后在Lecture听到professor讲研究了,记得要把握两个特别重要的信息:1. 研究结论是什么? 2. 研究后面是否出现了professor的态度观点。
托福听力需注意的细节 考点就在他们周围
托福听力两个Section下来,总会有种注意力越来越散的感觉。如果能够知道哪些地方预示着考点出没,那就相当赞啦!
1.Conversation:段落开头提到的原因必考:problem/question。
2.段落开头提到的本次主题必考(如Today……),段落结尾的点评和总结必考。
3.段落中重复两次的地方必考。通常为本节课的要点,师生各重复一次的地方必考,注意在笔记中划双线,重复两次的名词必考,一般重复的名词是选项中的替换词。
4.段落中的强调句型多引出分论点,是考点:
This is the first time…
One thing important is…
The most important thing…
You should remember/notice/bear inmind/keep in mind---conversation引出建议的句型。
5.针对上下文明显的肯定或者否定的回答必考:definitely,absolutely, exactly, it’s a good question, excellent question, 注意听好教授在这些回答之后的解释,一定会对重要内容作同义的重复。
6.段中主论点下有定义加举例的必考(配对表格题);
罗列多个事实处必考(是非型表格题);
说明多个程序、步骤的必考(排序题),中间的步骤一定注意:then, so, ok, well, replace, the next stage.
7.难点的解释说明必考(核心概念):小黑板,带字的笔记本,只要出小黑板都会有停顿。
注意引导词:it refers to, that is, that means, which means, This is to say, inother words, in another words, by that he meant, let me make it clear, let memake it simpler, let’s put it this way.
8.段中引用的观点必考,对应都是对分论点的看法:think,argue,believe,一定有小黑板,或者人物肖像。
9.形容词和副词最高级后面的点重要,themost important, biggest, 因为是形容重要特点。
10.一定注意教授跑题的内容,话题的转移、布置作业、一会儿再谈、我打算先谈些什么、谈一下个人的经历……会在语义理解上出题(细节)。
11.教授对学生的警告或指令必考(重听):Conversation表建议,Lecture中表强调重点。
12.托福听力出题的顺序和文章顺序完全一致,一定注意干扰选项:后面的内容在本题中会作为干扰项出现。
13.一定注意教授的点评,会作为结尾的题目出现(whatdoes the prof think of)。
托福听力分阶段备考规划
托福听力准备阶段
1. 基础词汇和场景词汇的积累
在刚开始备考托福听力的时候,可以先从《大学六级词汇》记忆,然后再去记忆托福红宝书。同时可以建议背诵《词以类记》补充场景词汇。
托福听力备考阶段
2.1听写训练
这个方法适用于时间充足的新手。在听写的材料上一般可以选择老托福,TPO以及SSS。难度是从左往右依次升级的,但在推荐程度上却是从左往右依次降级的。
具体步骤:
step 1. 总体听一遍材料,大概了解一下
step 2. 将文章第一句句子听一遍,写下来,直到把它完全写出来,3~5遍
step 3. 根据自己的文本再听一遍,适当做一定的笔记,掌握整体脉络。
一篇老托福PARTC需要一个小时,TPO全篇听的话需要甚至2个小时。所以建议在听写的时候精选长一些的句子。
2.2精听训练
这个方法是进阶版,适合于大部分文章脉络可以听懂,但是在听长难句的时候依然会有部分句子漏听或者反应不过来
具体的步骤:
Step1.掌握文章大意,记住没有听懂的,听3~5遍
Step2.一句一句的听,不停顿,记住没有听懂的
Step3.以单词为单位的听
Step4.听的时候看文本,然后总结听不出来听不懂的单词,句子,搭配
这个方法短而有效,而且对于听力段子的整体结构,从大意到句子再到单词都有一个比较好的理解。
2.3 结构法
当我们能大致理解文章大意的时候我们就要开始采取结构听力法掌握出题点。教授讲课的内容都有层次的。lecture只需要掌握结构。在听lecture时,首先要学会抓教授在什么地方分点。在 lecture 中,在转折、强调的词和句子处寻找结构划分点。再利用结构笔记,。建议学生每次做完题目,去分析讲座的结构,每一个学科文章的共通性。
2.4 背景知识法
这个方法适合一些学生在备考时候遇到的一个问题:字面意思上明白,学术层面上不理解。这个时候就需要备考者们去补充背景知识。
推荐的材料有:TED,国际地理杂志
2.5加速练习法
这个针对平时基础已近有23分以上的学生。在练习中可以将速度调制1.2,适应语速以后可以开始记笔记,一开始正确率可能会因语速所影响。练习一段时间以后再回到1.0速度,保证正确率要高于加速听的正确率,练习几天以后当正确率慢慢开始提高可提速到1.5来练习。

托福听力配对题怎么做?
要想轻易拿到配对表格题的分数,并且不过多占用有限的答题时间,我们需要分析了解表格题的出题规律。配对表格题的特征比较容易把握,往往在文章中会出现两个人或物,对它们多方面进行比较与对比。在听文章时,要对对是否可能会出现表格题进行预判,掌握先机。
例:In the lecture, the professor discusses characteristics of folktales and fairy tales, indicate the characteristics of each type of the tale...Click in the correct boxes. This question is worth two points.
在这道题目中明显提到discusses characteristics of folktales and fairy tales,因此可以看出他们之间是相互对比,并且他们之间是有差异的。通过文章的开头部分我们就能得出本篇文章的主要内容就是童话和民谣的区别,因此对于这两种故事要在听的过程中着重他们的区别以及自身的特点。
选项1:Their appeal is now mainly to children
这句话在文章的最后体现出来,So why is it that fairy tales seem targeted toward children nowadays?用反义疑问句的形式表达了童话故事对于儿童来说很受欢迎。通过结尾原则和因果原则,在听的过程中应该记录到fairy tales和children.
选项2:The plot is the only stable element
对应文章中的讲到同一个民间故事因为时间、地方等也会变得不一样,故事Because of this, elements like place and time can no longer be tailored to suit a particular audience,暗示只有情节不变。因此属于Folk tales.
选项3:The tales are transmitted orally
对应文章中So, what's a folktale? How would you characterize them? Jeff?,They were passed down orally within cultures from generation to generation,通过教授和学生的一问一答就可以看出folktale是通过passed down orally。在听的过程中,问答原则也可以为考生提醒这里是重点所在。
选项4:There is one accepted version
对应文中But with a fairy tale, it's always there in a book, waiting to be discovered, again and again. 因此可以看出童话故事只在书本上这一种被接收的方式。通过转折原则记录关键信息,a fairy tale、 always in a book即可得出答案。
选项5:Characters are well developed
通过上面几个选项的分析,我们知道民谣是通过口口相传,而童话故事只出现在书本上,很显然只有童话故事的角色塑造要比民谣塑造的好。还可以通过找出对应的原文But in fairy tales, people no longer have to remember plots. So more energy can be put into other elements of the story like character and setting. character and setting被很好的塑造因此本选项属于童话故事。
选项6:The language is relatively formal
本选项和第五个选项的分析相同,因为书上的童话故事的语言是通过加工和认真修改的,而民谣通过人与人之间的交流相传,语言比较随便,因此语言比较正式的是童话故事。
托福听力:段子练习之地理冒险
Good morning, class. Before we begin today, I would like to address an issue that one of you reminded me of after the last lecture. As you may recall, last time I mentioned that Robert E. Peary was the first person to reach the North Pole. What I neglected to mention was the controversy around Peary’s pioneering accomplishment. In 1910, a committee of the national geographical society examined Commodore Peary’s claim to have reached the North Pole on April 6th’ 1909 and found no reason to doubt him. This judgment was actually confirmed by a committee of the US congress in 1911. Nevertheless, Peary’s claim was surrounded by controversy. Tins was largely due to the competing claim of Doctor Frederic Cook who told the world he had reached the Pole a four-year earlier. Over the decades Peary was given the benefit of the doubt, but critics persisted in raising questions about his navigation and the distances he claimed to have covered. So the Navigation Foundation spent an additional 12 months of exhaustive examination of documents relating to Peary’s polar expedition. The documents supposed Peary’s claims about the distances he covered. After also conducting an extensive computer analysis of photos taken by Peary at the pole, they concluded that Pierre and his companions did in fact reach the near vicinity of the North Pole on April 6th. 1909. OK, today we’re going to talk about exploration of the opposite end of the world, I assume you all read chapter 3 in our text and are now familiar with the names: Emerson and Scott.

托福听力练习:鹳靠捡垃圾生活
Humans aren't the only creatures who love junk food—many animals are known to enjoy sifting through our garbage to find edible treats.
And now we learn that some storks have stopped migrating from Europe to sub-Saharan Africa in the winter—they'd rather feed at landfills.
“They use landfill sites heavily during the winter and they travel very long distance to get to the sites.”
Aldina Franco of the University of East Anglia, one of the scientists who studied the storks' use of landfills in Portugal.
GPS tracking devices on 17 birds showed that the landfill life might mean up to 100-kilometer round-trips to feed—healthy distances, but far shorter than their historic migration routes.
“And also they use the nests throughout the year and look after the nests.
So these resident birds are in perfect condition, they are always ready to start breeding.
So as soon as spring arrives they're ready to go, the nest is in good condition, and they start breeding earlier.”
The number of storks overwintering in Portugal has shot up from fewer than 2,000 in 1995 to 14,000 in .
The increase appears to reflect both changes in behavior and a booming stork population in general.
The study is in the journal Movement Ecology.
The Portuguese landfills are slated to close in , with the trash diverted to covered recycling and composting facilities.
How will the storks respond?
Franco thinks they'll get back to basics.
“So the storks are social animals.
They live in colonies.
They migrate in groups.
So potentially as long as there are a few birds that still know the route, they can teach the ones that are currently residents how to migrate.”
不仅人类喜欢垃圾食品—许多动物也喜欢翻垃圾箱找寻食物。
而现在我们了解到一些鹳已经不再于冬天从欧洲向撒哈拉以南的非洲迁徙—因为它们宁愿在垃圾堆里寻找食物。
冬季它们严重依赖垃圾填埋场,而且要飞很远的距离才能到达。
东安格利亚大学的一位科学家,爱尔迪娜·弗朗科研究了葡萄牙鹳是如何利用垃圾填埋场的。
对17只鹳的GPS追踪定位装置显示垃圾填埋场的生活意味着觅食要来回飞行100千米,这可是段漫长旅途,但同它们过往的迁徙路线相比就变得微不足道了。
同时,鹳全年都需要栖居并照顾自己的巢穴。
因此这些没有迁徙的鹳现在过着很好的生活,它们总是随时准备进行繁殖。
因此春天一到,它们就做好准备,自己的爱巢处于绝佳状态而它们则提早繁殖。
在葡萄牙过冬的鹳数量骤增,从1995年的不到只,蹿升至的1.4万只。
数量上的增长总体上反应了鹳行为上的变化以及数量的增加。
这项研究已在《运动生态学》杂志上发表。
而随着垃圾进行回收及堆肥处理,葡萄牙的垃圾填埋场将于关闭。
届时这些鹳该如何应对呢?
弗朗科认为它们会回归以前的生活。
鹳是群居动物。
它们依靠群体而活。
同时也成群迁徙。
因此只要少数鹳仍然知道迁徙路线,就可以教会现在的居民们如何迁徙。

2020托福听力练习:智能传感器提高球技
Hall of Famer Ted Williams once famously commented that hitting a baseball is the hardest thing to do in sports.
Although Williams—a .344 career hitter—made it look easy, he had a point.
Hitting a round ball with a round bat squarely is difficult.
It's also an excellent example of some very entertaining applied physics.
No surprise then that professional baseball players are turning to science to improve their multimillion-dollar strokes.
Some approaches focus on the neuroscience of hitting—the deep internal brain mechanisms behind seeing the pitch and reacting to it.
But for more info about the swing itself, a sports tech company called Zepp Labs makes a sensor that can help break down those mechanics.
The sensor sits in the knob of the company's so-called “Smart Bat” and uses two accelerometers and a three-axis gyroscope to measure bat speed, hand speed, attack angle and other factors.
The sensor, which weighs only about eight grams, sends this info to a smartphone app via Bluetooth.
The app can then use this data to have an onscreen avatar reenact the swing, in the hope that the batter can pick up some details and make the necessary adjustments.
Zepp's sensors can also be fitted to golf clubs and tennis rackets.
Never one to mince words, Ted Williams also once said that pitchers were “the stupidest people alive.”
Hmm, maybe somebody could come up with a smart baseball to help them.
Against any Ted Williamses out there, anyway.
曾入主名人堂的泰德·威廉姆斯曾经评价打棒球是体育运动中最难的事情。
尽管威廉姆斯在职业生涯中很轻松就达成了344次的安打率,但他说的说法很有道理。
用一根圆棍子准确击打一个圆球可并不简单。
这同时也是非常有趣的应用物理学中一个典型的例子。
Zepp传感器体积约2.54cm一个小正方体约6.3g 外形靓丽坚固.png
职业棒球运动员通过科学帮助提高自己价值数百万美元的击球,这并不是新鲜事。
而一些方法则将重点集中在击球的神经科学方面—棒球运动员在看到球投出后做出反应,这背后所蕴藏的是大脑的深层机制。
但关于更多挥棒信息,一家名为泽普实验室的体育科技公司制造的传感器可以帮助突破大脑传统的机制。
该传感器位于这家公司“智能球棒”的把手处,其中的2个加速器及一个3轴陀螺仪能够对球棒速度、手速、打击角度等其他因素进行测量。
而这款仅有8克重的传感器可以通过蓝牙将信息发送到智能手机的APP应用程序上。
而接收数据后,APP应用程序则会在屏幕上再次重塑挥棒的立体影像,这样球拍就能接收细节信息并做出必要调整。
泽普公司的这款传感器也可以安装在高尔夫球杆及网球拍上。
无需过多赘述,泰德·威廉姆斯曾经表示投手是最愚蠢的人。
或许有人可以发明出一颗智能棒球来助他们一臂之力。
这样就可以反驳泰德·威廉姆斯啦。
1.come up with 想出
例句:Several of the members have come up with suggestions of their own.
有几位成员提出了自己的建议。
2.turn to 转向
例句:Tonight it's my turn to cook.
今晚该我做饭了。
3.focus on 集中
例句:The talks will focus on economic development of the region.
会谈将着重讨论该地区的经济发展。
4.pick up 拿起
例句:He picked his cap up from the floor and stuck it back on his head.
他从地板上拾起帽子,重新戴在头上。

托福阅读因果关系词介绍
托福阅读中的因果关系词其实有两类,一个是表示原因的:as、since、thanks to、as result of、because of、owing to、result from、due to、on account of、by virtue of、in that、attribute to;另一个是表示结果的:as a consequence、thus、hence、so、as a result、result in、contribute to、lead to、cause、breed、trigger.

However, its position with respect to the surroundings could bechanged by revolving either the inner cage containing the birds or the outerwalls, which served as the background. As long as the birds could see the Sun,no matter how their surroundings were altered, they went directly to thecorrect food box. Whether the box appeared in front of the right wall or theleft wall, they showed no signs of confusion. On overcast days, however, thebirds were disoriented and had trouble locating their food box.
Which of the following can be inferred from paragraph 4 aboutKramer’s reason for filling one food box and leaving the rest empty?
A He believed the birds would eat food from only one box.
B He wanted to see whether the Sun alone controlled the birds'ability to navigate toward the box with food.
C He thought that if all the boxes contained food, this woulddistract the birds from following their migratory route.
D He needed to test whether the birds preferred having the food atany particular point of the compass.
首先,我们来明确一下推断的定义(infer, imply, indicate),纵使它是推断题,也不是意味着这题是主观臆断,臆想或是联想得出的。这道题也是要通过提取题干中的关键词到文章中的明确位置,然后文中没有平铺直叙地告诉你答案,需要我们根据一些线索找到答案。
接下来我们来看一下这道题,题干中出现Kramer, filling one food box andleaving the rest empty定位在第四段第一句:with food in only one of the boxes,而解开这道题的重点就在于:reason。我们看到第一句话一开始说到,so, in another set of experiments,很明显,答案并不在这一段,而是上一段的最后。所以答案是B。

深度分析:
这个句子的主干部分是:
A fertile, plowed field is rapidly invaded whereas a neighboring construction site may remain virtually free of vegetation
whereas然而,表示对比,对比两种情况
修饰一:(by a large variety of weeds) ,介词短语
中文:被各种各样的杂草
修饰二:(from which the soil has been compacted or removed to expose a coarse, infertile parent material) ,从句,修饰a neighboring construction site
这个句子理解的难点应该就在这里了,这个从句把a neighboringconstruction site和may remain virtually free ofvegetation分开了,注意断句不要出问题。
中文:这里的土壤被紧压或移除过以至于露出母质层(不要去理解啥是parent material,学术名词)
修饰三:(for many months or even years) ,介词短语
中文:几个月偶然甚至是几年
修饰四:(despite receiving the same inputof seeds as the plowed field.) ,介词短语
中文:尽管得到了和这块翻耕地同样多的种子
参考翻译:
一块肥沃且被翻耕过的土地会被各种各样的杂草迅速入侵,然而一个邻近的建筑工地(这里的土壤被紧压或移除过以至于露出母质层)可能几个月甚至几年都几乎没有植被覆盖,尽管得到了和这块翻耕地同样多的种子。
托福阅读真题原题+题目
It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species' death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.
The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time — a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago, when approximately 95 percent of all species died, mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.
One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earth's orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species' survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events.

托福阅读真题原题+题目
The lack of printing regulations and the unenforceability of British copyright law in the American colonies made it possible for colonial printers occasionally to act as publishers. Although they rarely undertook major publishing project because it was difficult to sell books as cheaply as they could be imported from Europe, printers in Philadelphia did publish work that required only small amounts of capital, paper, and type. Broadsides could be published with minimal financial risk. Consisting of only one sheet of paper and requiring small amounts of type, broadsides involved lower investments of capital than longer works. Furthermore, the broadside format lent itself to subjects of high, if temporary, interest, enabling them to meet with ready sale. If the broadside printer miscalculated, however, and produced a sheet that did not sell, it was not likely to be a major loss, and the printer would know this immediately, There would be no agonizing wait with large amounts of capital tied up, books gathering dust on the shelves, and creditors impatient for payment.
In addition to broadsides, books and pamphlets, consisting mainly of political tracts, catechisms, primers, and chapbooks were relatively inexpensive to print and to buy. Chapbooks were pamphlet-sized books, usually containing popular tales, ballads, poems, short plays, and jokes, small, both in formal and number of pages, they were generally bound simply, in boards (a form of cardboard) or merely stitched in paper wrappers (a sewn antecedent of modern-day paperbacks). Pamphlets and chapbooks did not require fine paper or a great deal of type to produce they could thus be printed in large, cost-effective editions and sold cheaply.
By far, the most appealing publishing investments were to be found in small books that had proven to be steady sellers, providing a reasonably reliable source of income for the publisher. They would not, by nature, be highly topical or political, as such publications would prove of fleeting interest. Almanacs, annual publications that contained information on astronomy and weather patterns arranged according to the days, week, and months of a given year, provided the perfect steady seller because their information pertained to the locale in which they would be used.
1. Which aspect of colonial printing does the passage mainly discuss?
(A) Laws governing the printing industry.
(B) Competition among printers
(C) Types of publications produced
(D) Advances in printing technology
2. According to the passage , why did colonial printers avoid major publishing projects?
(A) Few colonial printers owned printing machinery that was large enough to handle major
projects.
(B) There was inadequate shipping available in the colonies.
(C) Colonial printers could not sell their work for a competitive price.
(D) Colonial printers did not have the skills necessary to undertake large publishing projects.
3. Broadsides could be published with little risk to colonial printers because they
(A) required a small financial investment and sold quickly
(B) were in great demand in European markets
(C) were more popular with colonists than chapbooks and pamphlets
(D) generally dealt with topics of long-term interest to many colonists
4. The word they in line 17 refers to
(A) chapbooks
(B) tales
(C) jokes
(D) pages
5. The word antecedent in line 19 is closest in meaning to
(A) predecessor
(B) format
(C) imitation
(D) component
6. Chapbooks produced in colonial America were characterized by
(A) fine paper
(B) cardboard covers
(C) elaborate decoration
(D) a large number of pages

(A) dependable
(B) respectable
(C) enduring
(D) attractive
8. What were steady sellers (line 23)?
(A) Printers whose incomes were quite large
(B) People who traveled from town to town selling Books and pamphlets
(C) Investors who provided reliable financial Support for new printers

篇6:托福听力高频题型主旨题解题技巧实例讲解
托福听力高频题型主旨题解题技巧实例讲解
做好托福听力主旨题无关词汇量从开头找线索
关于托福听力主旨题的解题技巧,考生应该首先注意的是这两种题型与大家词汇量的多少无关。也就是说,词汇量即使很少也不会给这两种题型的解题造成障碍。考生真正要做的是首先听准开头;特别是开头句型,之后找出对话目的;如果开头没有把握准,那么要注意全文重复词汇;最后要听准关键词并对实义词(名词、动词、形容词)足够敏感。
托福听力对话和讲座如何听准开头段?
那么,考生应该如何听准托福听力的开头段呢?大家要注意的是,在conversation和lecture的开头中,有的文章会出现寒暄部分。
比如,在conversation中两个说话者的在开头部分都会出现互相问好的寒暄语:
e.g.1 A : Hey, how is everything going?
B: Well, everything is going fine.
e.g.2 A: Hi, are you Paula?
B: Oh, hi, Jim. Nice to see you!
在这些寒暄之后说话人A说Do you need some tutoring in English? 说话人B说:yes, I am taking English composition and my English is not very good. 这才是文章的真正内容,也就是文章的主旨。所以选项的相应部分选择的是:She needs a tutoring appointment!
在lecture中,有时教授上来不会直接切入正题,而是先会寒暄几句。
例1: 有个教授上来先说I am sorry that I didn’t bring your paper, and it took longer to grade than I thought. So I will bring you the paper next class. Today, I want to continue our topic about Renaissance. 所以 “I am sorry that I didn’t bring your paper, and it took longer to grade than I thought. So I will bring you the paper next class.” 这句话都是在说与文章主旨无关紧要的话。而真正与文章主旨有关的是以today开头的这句话!所以,显而易见,这篇文章的主要内容就是文艺复兴Renaissance。
例2: In the last class, we discussed the Jazz music history. But today, I am going to talk about the development of the jazz music. 那么很显然,In the last class, we discussed the Jazz music history.这是上节课讲的内容。在强转折but之后,老师紧接着说I am going to talk about the development of the jazz music. 那么,文章的主旨也就很明确了。

Last week we talked about Anne Bradstreet and the role of women in the Puritan colonies.
上周我们谈论过Anne Bradstreet以及在北美殖民地中女性的角色。
Today I want to talk about some other women who've contributed to American history—some famous and some not-so-famous.
今天我想谈谈对美国历史作出贡献的一些其他女性——有些很著名也有些不著名。
The first woman I'd like to talk about is Molly Pitcher.
第一位女性我想要谈论的是Molly Pitcher
Those of you who are familiar with the name may know her as a hero of the American Revolution.
你们之中那些熟悉这个名字的,可能会作为美国独立战争的英雄而知道她。
But, in fact, there never was a woman named Molly Pitcher.
但是,事实上,从来没有一个女人叫做Molly Pitcher。
Her real name was actually Mary Ludwig Hays.
她真正的名字实际上是Mary Ludwig Hays。
She got the nickname Molly Pitcher for her acts of bravery during the Revolutionary War.
她得到Molly Pitcher这个外号是因为她在革命战争(美国独立战争)期间的英勇表现。
As the story goes, when Mary's—or Molly's—husband, John Hays, enlisted in the artillery, Mary followed, like many other wives did.
据说,当Mary的—或者说 Molly的—丈夫,John Hays,应征参加了炮兵,Mary跟随而去,像很多其他的妻子那样。
She helped out doing washing and cooking for the soldiers.
她帮忙为士兵洗衣做饭。
She was known to be a pretty unusual woman.
她作为一个相当不寻常的女人为人所知。
She smoked a pipe and chewed tobacco.
她抽烟斗,并且嚼烟草。
Anyway, in the summer of 1778, at the Battle of Monmouth, it was a blistering hot day, maybe over a hundred degrees, and fifty soldiers died of thirst during the battle.
总之,在1778年的夏天,在Monmouth之战,那是极热的一天,也许超过了100度,在战斗期间五十名士兵死于口渴。
Molly wasn't content to stay back at camp.
Molly不满足于留守在营地。
Instead, she ran through gunshots and cannon fire carrying water in pitchers from a small stream out to the thirsty American soldiers.
相反,她跑着穿过枪林弹雨用水罐从小溪中打水送给口渴的美国士兵。
The relief that she brought with her pitchers of water gave her the legendary nickname Molly Pitcher.
她用她水罐里的水带来的安慰(的事迹),给予了她传奇的绰号Molly Pitcher。
The story also says that she continued to load and fire her husband's cannon after he was wounded.
这个故事还说,她在她丈夫受伤之后继续用他的炮装弹并开火。
They say she was so well liked by the other soldiers that they call her “Sergeant Molly.”
据说她是如此地受到其他士兵的喜欢,以至于他们称呼她“Molly军士”
In fact, legend has it that George Washington himself gave her the special military title.
事实上,传说George Washington亲自给予了她这个特殊的军衔。

Before I tell you about the interesting discovery related to Tyrannosaurus rex, I need to review something we studied last semester, the difference between what are commonly called cold-blooded and warm-blooded animals.
在我告诉你们和Tyrannosaurus(暴龙/霸王龙)rex(雷克斯霸王龙/雷克斯暴龙)有关的有趣发现之前,我需要回顾一下我们上学期学过的内容,通常被称作冷血和温血动物之间的区别
In warm-blooded animals, birds and mammals, for example, the body temperature normally stays within a narrow range, no matter what the outside temperature is.
在温血动物中,举例来说,鸟类和哺乳动物,体温通常保持在一个小范围内,不管外面温度是多少。
As a result, a warm-blooded animal is usually active in both cold and hot weather because its body temperature can adjust to the temperature of its environment.
结果,温血动物通常在冷热天气中都很活跃,因为它的体温能适应它的环境温度
On the other hand, cold-blooded animals, such as most reptiles, amphibians, and insects, are unable to create enough heat internally to raise their temperature above the temperature of the environment.
另一方面,冷血动物,比如大多数的爬行动物,两栖动物,和昆虫,不能产生足够的内在的热量来把它们的温度提升到环境温度之上。
So, for example, the temperature of a cold-blooded animal falls when the environment is cool.
所以,举例来说,当环境冷时,冷血动物的体温会下降。
I hope this distinction is clear. Now, moving on to Tyrannosaurus rex, you may know that dinosaurs, being reptiles, are generally believed to have been cold-blooded.
我希望这种区别是清晰的。现在,转移到霸王龙rex,你可能知道恐龙,作为爬行动物,通常被认为是冷血的。
Well, a recent research study found that the chemical composition of the bones of Tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm-blooded.
好,最近的调查研究发现霸王龙 rex的骨头的化学组成同内部温度有很小范围(变化的)动物的骨头是一致的,表明它可能是温血的。

篇7:托福阅读难点题型如何提升正确率
托福阅读难点题型如何提升正确率?2个方法针对性解题
托福阅读难点题型解题思路:多选题关键在于题干
托福阅读每篇文章最后一道题一般都是多选题,多选题分两类,一类叫图表题,给你一个图表,让你6选3。第二类叫文章内容小节题,先给你一句话,这句话就是这篇文章的中心思想,请问下面哪几个选项中反映了这篇文章的中心思想。这样的话,这个题目是我们的第二个问法,这是阅读中我们最常见的两种多选题,这种题同学们不要有畏惧心理,因为这类题目分值也比较高,一般是2分或3分。我们即使答错一个空,3分题还会拿到两分。
托福阅读难点题型解题思路:插入题重在考察句子间关系
在托福阅读中有那么一个段落,其中有4个框,代表你在题干中的那句话可以放到这个位置来。做题的方法是:第一步一定要优先阅读题干中要被插入到原文的那句话。第二步找要被插入原文那句话当中的关键字和要点。因为我们知道,如果要把一句话插入到原文当中,这句话肯定和原文有很强的关联性。
然后我们找的是要被插入原文那句话中的关联词,这有很多,比方说一旦看到“因为”,前面讲的就可能是原因,因为这个结果后面有一个情况;再比如你看到THIS,通常表示结果。那么正确选项在第一个空和第二个空的可能性不是很大,在第三个空和第四个空的可能性比较大,因为它表示结果,基本都在比较靠后的位置;比如我们看到in contrast,跟前面正好是相反的,所以说这些关键词特别重要,从一定意义上来讲是我们做这种题型成败的关键。
我们要找逻辑关系,你要插入这句话,跟前面或者后面的话肯定有一种逻辑关系在里面,到底前后是转折还是递进还是表示结果还是什么样的关系,这是我们的情况。一般来说,多数中国同学做这个题还是比较出错的的,小编建议大家在备考的时候大量练习此类题目的做法。

托福考试阅读技巧:高端英文
有些同学已经将单词背的滚瓜烂熟,句子结构也已略通门道,但在阅读英文长篇文章后,不知道作者的“重点在哪里”,或者刚读完,就忘记作者“写的是什么”的同学。因此,在准备进一步提高阅读速度及水平之前,请首先保证自己的背词次数和拆句能力过关。而且要在做题(改错)时积累一词多义或者特殊句式,提升自己的理解准确性。
对于已经掌握单词和单句意思的同学,很容易陷入到一个误区里面,那就是过度地揣摩单词和单句,(毕竟好不容易背下了大量单词,解构了很多句子)但没有抓住文章的主要逻辑和目的,也就是光看,没想。
另外,“每个单词都懂但是一句话不懂”和“每个句子都懂但是整篇文章不懂”根本就是两个不同的概念, 前者很大原因在于 单词组合 或习惯用语 不知道,说白了还是单词量短语量不够;后者更多的是没搞清楚文章逻辑。
可行的解决方法:
1.首先搞清楚英文材料的类型:
大家经常会读到,或者考到的都是“学术说明文”“议论文”或者“小说”这一类的。
2.学会正确的阅读方法:
不同的文章有不同的阅读方法,绝大多数好的英文文章逻辑性都很清晰,对于TOEFL 和 GRE这两种考试而言,除了搞清楚文章每句话的意思之外,还要搞清楚“为什么这句话在这里”,作者写这句话的目的是 “表达一个观点”,“证明一个观点”,“阐述事实”,“提出问题”, “提出解决方案”还是什么别的。 学术文章什么的格式都应该很固定的。总之就是多思考为什么。对于小说而言,不要过分注重情节发展,一个资深的阅读者应当注重由小说的情节体现出的人物性格以及情感,这些也经常是考点所在。
3.记笔记,做整理,搞输出
在阅读说明文、议论文时要一边看一边记:
主旨句(一般为首句):即 “这一段讲了什么” ,需要精读。
解释或举例部分:一般扫读即可,但当主旨句难以理解时,要精读。
比较部分:即“这一段比较了X.X和YY”,要注意作者希望体现比较主体的什么特征。
最高级及强调句:即“这一段表明X.X很NB” 之类的。
转折词:当遇到转折词时要格外注意,作者希望强调的是后面的内容。
在做题时,可以用题目来定位阅读的位置,然后使用上述方法进行阅读。在做题后,如果能够结合笔记,向别人复述一下文章的主要内容,效果最好,毕竟能讲明白了基本就算看明白了。
最后,同学们可以尝试着模仿学术文章的结构来创作文章。写一篇文章的时候会思考文章的组织,结构,逻辑关系什么的。想的多了,看别人文章的时候就会经常会心一笑,”原来这么一大段纯粹就是来凑字数的,skip之”。
三大托福考试阅读技巧
1、掐时间、整套做题
每篇文章不超过20分钟、一次性三篇一起来;不要一篇恒久远,也不能一次就一篇。以免考试的时候体力不支和时间不够。
2、不翻译的精读,分析文章逻辑
做完题目对完答案之后,第一步:扫生词。找出(尤其是做TPO的时候)不会的单词,当然特偏门的专业名词可以放一放,记下来背下来。第二步:找出不理解的长难句,拆解之、分析之。第三步:仔细阅读文章,找到逻辑关键词、关键句,划分文章、段落间的关系和结构。
3、善待错题
做题对答案不是终点,把文章中的生词摘出来也不是终点,一定要注重分析错题这个步骤,了解你的易错题目类型以便你专项练习;了解正确选项正确在哪儿、错误选项错误在哪儿,以便我们避开错误选项里的陷阱,成功提分;还能够了解题目答案定位何处,认识到怎么定位才是对的……
托福阅读技巧很重要,但是平时也要注意自己对托福阅读背景知识的输入,多看一些《经纪学人》等信息量较大的外刊,帮助我们高效的提高托福阅读的水平。
篇8:托福听力重听题出题思路实例讲解
托福听力重听题出题思路实例讲解 简单题型保分也要学技巧
重听题出题方式介绍
重听题意在考察考生能否理解说话人说这句话的原因,目的和态度,能否明白字面以外的意思。大致有两种典型的提问方式:
· What does the professor imply when he says about this?
· Why does the student say this?
另外,重听题的出题点常在文章明显语气变化处,或者话语转换处。
重听题解题思路实例分析
官方真题Official1-L4为例
Student: Oh, I see. At first I wasn’t sure what growing season meant, just from the reading. But now I get it. It's the amount of time it takes for them to grow, right? So it would be five months?
Professor: Umm? Oh, uh… I’m sorry but no. It has nothing to do with that. Why does the professor say this
A. To inform the student that his definition is incorrect
B. To suggest that the student did not do the reading
C. To encourage the student to try again
D. To change the topic of discussion
这道题的出题点在professor 的语气处。“Umm?Oh…I’m sorry but no.”
主要解题思路如下:
1)解释说明:解释说明题多出现在教授提出一个大家不认识的单词或者不熟悉的现象之后,直接解释或者通过问题来引出解释。
2)纠正错误:重听题中的纠错多表现于教授对于学生所说的内容的纠正。
3)举例论证:重听题中学生或者教授会用自己的故事或经历来表示支持所表达的观点。
官方真题Official7 Lecture1为例:
Professor: This is the inciting incident. It sets off, the plot of the play.
文中教授先提出一个专有名词,第二句是对专有名词inciting incident的解释。
官方真题Official1-L4为
Student: Oh, I see. At first I wasn’t sure what growing season meant, just from the reading. But now I get it. It's the amount of time it takes for them to grow, right? So it would be five months?
Professor: Umm? Oh, uh… I’m sorry but no. It has nothing to do with that.
Why does the professor say this
A. To inform the student that his definition is incorrect
B. To suggest that the student did not do the reading
C. To encourage the student to try again
D. To change the topic of discussion
解析:请注意虽然问题的考点是后面那句话“It has nothing to do with that”但是如果你听出了professor的语气的话,你甚至可以在还没有听到后面那句陈述句的时候就能够从她前面的语气中明白她对之前学生讲的这番话的态度了。很显然她是在纠正学生的错误,所以答案选A。
题型总结
重听题是比较简单的一类题型,考生要在平时积累单词的基础上要多听多练习。相信大家在熟练掌握了以上内容之后,重听题的正确率就可以大大提高。

“The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics with one half to David J. Thouless and the other half to F. Duncan Haldane and J. Michael Kosterlitz for theoretical discoveries of topological phase transitions and topological phases of matter.”
G?ran Hansson, secretary general of the academy, this morning. All three new Laureates were born in the U.K. and went on to U.S. institutions. Thouless is emeritus professor at the University of Washington. Haldane is at Princeton. And Kosterlitz is at Brown University.
“Professor Nils M?rtensson, the acting chairman of the Nobel Committee, will provide some introductory remarks on the Nobel Prize in Physics:”
“This year's Nobel Prize recognizes important discoveries in the field of condensed matter physics. And today's advanced technology, take for instance our computers, rely on our ability to understand and control the properties of the materials involved. And this year's Nobel Laureates have in their theoretical work discovered a set of totally unexpected regularities in the behavior of matter, which can be described in terms of an established mathematical concept, namely that of topology. This has paved the way for designing new materials with novel properties. And there is great hope that this will be important for many future technologies.”
Following the announcement, Haldane joined in by phone to talk about the discovery.
“And at the time I felt it was of scientific interest and mathematical interest and very fascinating, as a consequence of quantum mechanics that we hadn't guessed at. But I didn't think it would ever find a practical realization. But if something is actually possible it'll eventually, with material science, any kind of unexpected possibilities will lead to some concrete realization.”
“And these materials would have a possibility that information, either electronic or in other versions, could travel in one way around the edge of the system without the possibility of the information in the signal being disrupted by impurities or bends in the path. And so this aspect of things at least has a theoretical possibility of having great practical implications in subjects like the dream of building quantum computers. So it's taught us that quantum mechanics can behave far more strangely than we would have guessed. And we really haven't understood all the possibilities yet.”

2020托福听力练习:驯化家猪或含野生祖先基因
The standard story told about domesticating wild animals goes something like this:humans selected individuals with a desired trait—docility, for example and bred those animals together to produce offspring even more docile than their parents.
Eventually the breeders created a genetic bottleneck that separated domestic animals from their wild relatives.
And they brought their livestock along as they spread across Europe and Asia.
But now a group of scientists has demonstrated that the story is far too tidy—at least when it comes to pigs.
Pigs were domesticated from wild boar at least twice, in Anatolia in present day Turkey and in the Mekong Valley in China, both about 9,000 years ago.
They arrived in Europe about 7,500 years ago.
For this study, researchers focused on European pigs.
They evaluated more than 600 genomes from European and Asian wild boars and domesticated pigs.
And they found that, in Europe, the story of a bottleneck separating domestic from wild animals does not fit the genetic data.
Rather, the model that does fit indicates that there was a frequent flow of genes from wild European boars into the domestic population.
In other words, boars and pigs kept finding ways to get together.
The most likely scenario for the development of the modern pig genome includes gene flow from some species of European wild boars that are now extinct.
But their genes live on, on the farm.
The research is in the journal Nature Genetics.
The authors hope this study will prompt the use of genetics to evaluate the domestication history for other species, including dogs and horses.
They say the incorporation of contemporary and ancient DNA into these modeling scenarios will help elucidate the timing of the domestication of plants and animals and, “ultimately substantially enhance knowledge of this fascinating evolutionary process.”
篇9:2020托福口语TASK1答题思路实例讲解
遇到这样的题目,首先要确定一个topic sentence,然后再迅速地构建supporting Ideas. Topic sentence 一般比较好确定,关键再与能否用具体的details 和 examples 有力支撑你的topic sentence.
考生在拿到这个题目后,最好迅速的针对这个famous person 身上的特质做一个分类,比如他的achievement 和他的character. 确定好从这两方面展开叙述后,就应当分别找出各自具体的examples. 比如你要写一个作家的话,在achievement 方面,你就可以简单列上作家的书名以及此书如何改变了你人生观,以及帮助你养成良好的习惯等。而在character方面,你就要以你脑袋里出现的几个形容人的单词为点。
此时,在15秒的准备时间里,考生最好在纸上简单的写下几个对你有提示性的单词。如humorous, open-minded, easy-going, warm-hearted, knowledgeable, versatile…。然后再连点成线,组合成句子。然后我们可以用描述的方法把观点同意转换,如He is warm-hearted and he never hesitate to help those in need.我们也可以用举例的方法来进行扩展,比如He is versatile and he’s not only a famous writer but also an excellent racing drivier。
托福口语范文:放弃一个社团
题目
You are the members of two clubs in your school, but you have to quit one because this semester you have a lot of schoolwork to do. Which one do you prefer to quit? And why?
1)hiking club
2)speech and debate club
Sample Response
If I were too busy to participate in both the hiking and speech club, I would quit the hiking club.
Although hiking is fun to do with friends, I can do it on my own whenever I have time. By contrast, it is impossible to get feedback about a speech or participate in a debate by myself.
Plus, I want to focus on things that will help me get a good job. Speech and debate are important work skills, so I think it is better to practice those now and do hiking later when I have more time.
Because speech and debate are hard to do on my own but are important for getting a good job, I would keep attending that club.
托福口语范文:家长是否要帮孩子解决困难
题目
Some parents prefer to help their kids to solve the problems and troubles they meet, while some parents prefer to let their children deal with difficulties by themselves. Which one do you think is more reasonable and why?
Sample Response
I think that parents should let kids solve their own problems and troubles. Of course, there are some dangerous situations where a parent should help, but for the most part, children should be allowed to come up with their own solutions.
First, parents need to remember that they will not always be there to help. Children will face many situations in the future on their own, so they need to become comfortable solving problems on their own.
Second, children will remember how to do things better if they solve problems. Even if they make mistakes, the kids can learn what not to do. The process is important for understanding how to solve other troubles in the future.
Therefore, I think that, when possible, parents should let kids learn to solve their own problems.
篇10:托福口语TASK1答题思路实例讲解
我们以人物类为例。首先人物类的题目一般会要求你对一个人进行描述,比如你所尊敬的人或者对你影响很大的人,并且会要求你用具体的细节及例证进行支持自己的观点。如之前某场考试出现过的口语TASK1:Describe the famous person you admire most. Explain why you admire this person. Include details and examples to support your response.。
