理科的考试时间分配方法（精选6篇）由网友“JanusLausDeo”投稿提供，以下是小编为大家准备的理科的考试时间分配方法，仅供参考，大家一起来看看吧。
篇1：理科的考试时间分配方法
一.理科的考试时间分配
理综考试如何合理分配时间(一)
根据分值和难度分配每科的做题时间，生物最简单占分数也最少，大概需要25分钟完成;化学是100分，难度在三科中属于中间的，大概需要50分钟来完成;物理最难分值也最高，需要一个小时，剩下的15分钟先检查一下个人信息以及答题卡，看看有没有漏掉的题，然后再做没有做的题(之前不会落下来的)。
有的同学不习惯每科分开做，那就根据这个时间分配和自己做题的习惯安排一下每道题大概要多少时间。
理综考试如何合理分配时间(二)
一般大家做题的时候都是从头往后做，做题的时候要注意，仔细审题，简单的一次性做对，难的(读不懂题或者不知道从何下手)就先放着，做其他的题，切莫在一道题上浪费时间，做出来了还行，做不出来既浪费时间又打击自己。
选择题难的不要超过3分钟，计算题不要超过5分钟。如果答案比较复杂计算量比较大的话，可以不写答案了，计算题的最后答案是1分。
理综考试如何合理分配时间(三)
卷子发下来以后，填完个人信息，这个时候开始答题的铃声还没响，就不要着急做题，先浏览试卷，把三科的题目都分开(大概记一下或者标记出来)，做题的时候如果是每科都分开做的话，就比较清晰了。
最好是从头做到位，先把简单的题都做了，再做有点难度但是有思路的题，最后剩下没有思路的，根据题干写上相关的公式或者概念，得一分总比0分要好。
二.理科的考试时间分配
理综考试时150分钟做300分的题。按分值分配，选择题时间大约安排应在45分钟左右完成，非选择题时间大约安排105分钟内完成为宜，留有检查时间。
理综用时分配：9:00—9:50选择完成;——10:30物理完成;——11:05化学完成;——生物完成(注意：作答生物主观题时一定要先完成40选考题<选修3>，再依次完成29～32必考题)。
理综时间150分钟，总分300分，所以基本的用时分配原则是，每2分用时1分钟。理论各科用时应该是物理55分钟、化学50分钟、生物45分钟。
全国卷理综考试题目从头做到尾按顺序做。如果遇到一个题目，思考了3—5分钟仍然理不清解题的思路时，应视为难题可暂时放弃，即使这个题目的分值再高，也要忍痛割爱。千万不要因为捡了芝麻丢了西瓜，因小失大。
做选择题速度不宜过快，对于没有把握的题随时标记，以后复查。审题要细，对于选项是定还是否要有根据，充分利用单选的特点，用好排除法和推理法。
三.理综考试各科怎么安排时间更合理?
1.理综考试生物和化学大题的时间平均为每个题10分钟，有些题大一点，可以花15分钟，如果需要的时间更长，建议先做完后面的再来处理这个东西。
2.理综两个物理大题花的时间比较多，难度也较大，很容易出现怪题，所以即使是优等生也不建议一次性做出来，所以先把会做的做完，回头再来处理这个东西。这部分时间安排25-30分钟。
3.理综考试将所有会做的做完后，你会剩下10—30分钟的时间，这时候去解决那个没做完的物理大题和其他没解决的问题，估计你的时间会刚刚好。

一.理科的考试时间分配
全国卷理综考试时间分配技巧
理综三科合一，按分值分配，选择题时间大约安排应在45分钟左右完成，非选择题时间大约安排105分钟左右完成为宜。
做理综题时，基础题要力争全对，中档题少丢分或者不丢分。中、低档题得分数通常占全卷的80%以上，如果你能拿下各学科的中、低档题，就能够获得高分，而你有了高分垫底的心理优势，再做难题也会有信心攻克。
全国卷理综考试答题顺序
1.全国卷理综考试题目从头做到尾按顺序做
优点：可以避免丢题,漏题，节约时间.
缺点：有时遇到看似简单，实则不易的难题时常常由于忘情投入，直等到发现身陷泥潭，已经进退两难，已经耽误了大量宝贵时间，使后面许多能拿分的中、低档题都没有时间做。
如果遇到一个题目，思考了3—5分钟仍然理不清解题的思路时，应视为难题可暂时放弃，即使这个题目的分值再高，也要忍痛割爱。千万不要因为捡了芝麻丢了西瓜，因小失大。
2.先易后难，从容答题
理综考试每科试题一般都是先易后难，若遇到难题，可以暂时跳过去，先做后面学科的容易题——等做完各科相对容易得分题以后，再回过头来做前面的难题。
全国卷理综考试做题原则：能拿到手的的分就先拿住——手中有分，心中不慌，然后再回头做难题，能做多少就做多少，得分少些不遗憾，得分多你就赚了!
3.先做自己的优势科目，再做其他科目
对于理综考试先做优势学科，既可以先拿到比较有把握的分数，做题时做出一个好的心态，又可以为非优势学科留有充分的时间。避免一开始就遇到难题使心情郁闷，使头脑发蒙的现象。
总之，对于多数考生来讲，要在有限的时间内获得比较高的分数，就要学会主动地暂时放弃，暂时放弃费时费力的难题，腾出更多的时间做容易题，拿到更多的分数
二.高考理综考试技巧
1.统揽全局，合理安排
拿到试卷后，切勿急于答题，首先要看清试题说明的要求，例如开头说明的一些常量取值，元素的原子质量等。还要看清共有多少道题，多少大题，多少小题，反面有无试题，一方面可以防止由于紧张而漏做试题，另一方面心中有数，便于计划具体的答题时间。要注意是否有缺页现象，如有应立即报告监考老师。
在高考中各科的时间安排与模拟考时略有不同，一般按照分数比值作相应的分配，每二分值占时一分钟。物理、化学各55分钟左右，生物40分钟左右比较合理。当然如果某一个学科题目较难或者某一学科的分数的比值稍微多一点时间也就应该多一点。同时自己的优势学科可适当减少时间，劣势学科可适当增加时间。
2.缜密审题，扣题做答
“磨刀不误砍柴工”，拿到一个题目，一定要花必要的时间(约10%左右)看清题目、弄清题意。首先要全面、正确地理解题意，弄清题目要求和解答范围，比如结果保留几位有效数字，重力加速度g取9.8m/s2还是10m/s2等，然后根据要求，抓住重点，认真作答，这样才不会答非所问。审题不认真也会造成大量失分，如将理综第30题中要求的O、B之间的绳烧断，看成烧断A、B之间的绳，一分不得，造成终生的遗憾。
在审题时，要特别重视题目中的关键词，如物理试题中的静止、匀速、匀加速、初速为零，、自由落下、一定、可能、正确的等词，还要特别注意逆向题中的关键词，如不正确的、错误的、不可能的等等。
3.深刻理解，描绘情景
理综试题，文字描述的可能是一个复杂的运动过程，它可以分成几个不同的阶段，每个阶段中可能有题中所给的已知量，也可能隐藏在题中未给的量或通过作图来描绘情景。
对于头脑不清的问题，可通过作助解图，对物体进行受力分析，分清运动过程，从而获得更多的信息，以利于找出解题的有效途径，帮助我们正确地建立有关未知量与已知量的关系，可以说正确的作图分析，是解题成功的一半。
4.先易后难，从容解答
高考理综考试与单科考试有很大的不同，理、化、生在同一张试卷上。Ⅰ卷一般按生物、化学、物理的顺序，Ⅱ卷按物理、化学、生物的顺序排列，每科中一般是先易后难，有时碰到难题，一时难以解答，可以先暂跳过难题，先做后面的容易题。
如果避易就难，啃住难题不放，只会费时甚至会影响对容易题的做答，还可能造成紧张的心理状态，打乱思路和步骤。过去有的考生就是吃了这个亏，到收卷时，前面的化学难题没有啃通，后面的物理易题也未做好，这是应当记取的一个教训。
一般来说，遇到一个题目，若思考了3—5分钟仍然理不清解题的思路，应视为难题可暂时放弃，即使这个题目的分值再高，也要忍痛割爱，而把精力放到解容易题和中档题上，以便节约时间，等有时间再回头来攻克难题。要知道在高考中时间的安排是否合理对你成败有着十分关键的作用。
篇3：英语六级考试时间最佳分配方法
英语六级做题时间分配方法：
写作：一共30分钟，只能提前不能推后。大概用2MIN时间审题，立意，确定不要让文章跑题，另外用3MIN时间大概构思，写出文章框架。剩25MIN，动笔书写，注意自己一定工整，不要拼错单词。
听力：开始前一定要先浏览题目或者对话选项，短文要先阅读和了解问题，以免听的时候没有主次，重要的.是一边做题就要一边把选项涂在答题卡上，因为没有另外的时间让你专门填涂。
两篇精细阅读和一段翻译。总的来说时间还是有些紧，要先选自己拿手的做，或者按照平时训练的顺序来做。建议15选10用5MIN， 信息匹配题15MIN，精细阅读30MIN(每篇15MIN)，翻译20MIN。
篇4：雅思写作考试时间分配方法
很多人理所当然的把顺序定为“先大后小”，即先写大作文后写小作文可以让我们从时间和得分上都占得先机。其实完全可以根据个人习惯进行，小作文随从理论上讲分数占比小，但小作文在整体分数影响上也很可观。并且，小作文思路好成型，遣词用句较固定，在紧张的考试中先写并不矢为一个很好的选择。具体来讲：
STEP1: 审题(1min)
以大作文为例，审题并通过分解标题句来找到核心词汇key words(通常情况下为名次或名词词组)，写作时严格围绕着该核心词汇组织文章，以免出现偏题走题的失误。 同时，在下笔前找出该词或词组的同意替换避免重复同时达到用词多样化的目的。如：
Some people think that cheaper and cheaper travel by air is becoming beneficial, others think it has drawbacks to environment and the resources of the world. Discuss both views and give your own opinion.
key words=travel by air= air travel=go to...by plane?
beneficial=benefits=advantage=merit,
同理，我们可以把drawbacks，environment，resources等进行同义转换和细化，从而避免在写作的过程中忘记换词或者因为总是想着怎样换词而影响了思路的顺畅。
STEP2: 确立结构(0.5min)
根据题目中的问题形式来确定书写方法和段落划分依据。对于书写格式及结构通常在课堂中会被反复提及并练习，考生对于这一部分较为熟悉，需尽量缩短时间。
STEP3: 论点(3min)
把平日积累的全能论点论据充分罗列，尽可能多的拓展思路，不需要很具体，只是作一部分提示，这样要比边写边想来的有依据的多。列论点之初，不要形成思维定势直接倾向于论点的某一方，但在构思过程中如果很明确发现一方论点较少，可直接选择其作为反方。
STEP4: 论据(2min)
这一步完全可以在脑子里进行，目的有两个，一是搜集例证或理论依据证实论点，二是筛选论点。在整理论据的过程中如果发现某一论点很难找到相应论据，则启用该观点。到这里正篇文章的'雏形就完成了。
STEP5: 成文(30min)
成文过程会比较轻松，因为大部分需要思考的工作在前四步已经完成。在写作的时候只需要不断提醒自己不要犯低级语法错误，尽量多的调动自己积累的词汇量和语法储备就可以了。
希望各位考生可以在考试的时候合理安排时间，充分利用有效时间，在写作中拿到理想成绩。
篇5：雅思阅读如何合理分配考试时间
雅思阅读如何合理分配考试时间
正确的时间分配可以帮助考生在考场上最大限度的发挥自己的实际水平，提高整体正确率。合理的时间安排，原则上是18分钟一篇。但是考生都有自己熟悉的话题和有把握的题材。所以，在正式开始做题之前，考生不妨可以通过标题浏览等方式Skim三篇文章，按照自己的实际情况对于三篇文章的难易程度进行定位，确定哪篇文章是自己把握性比较大的，对于这种比较有把握文章一定要保证时间充足，这样有助于整体正确率的提升。但是每一篇文章原则上最多不超过20分钟，否则考生是没有办法有效率的完成40道题目的。
在时间分配这一点上，要特别提醒那些基础比较好的考生。因为此类考生往往更加容易“栽跟头”。雅思阅读文章篇幅较长，之后还有四十道题目需要完成，这就要求考生精读和泛读相结合。需要提别提出的是，文章中的信息有主次之分，那些与考题相关的信息才是考生需要精读的内容。而基础较好的同学往往为了保证正确率会采取全篇精读的方式去完成题目，这样的话就没有办法保证在规定的时间内完成所有题目。
最后需要在时间安排上提醒考生们注意的是，要留取填写答题卡的时间。雅思考试第一场听力考试是有10分钟的时间留给考生填写答题卡的。但是在紧接着的第二场阅读考试中，填写答题卡的时间包含在一个小时考试时间里面。在此，有不少老师建议考生，分篇填写。完成一篇之后就把填写在答题卡上，这样可以避免最后完全来不及填写答题卡的情况出现。
除去时间掌控之外，考生们在考场上还要注意的是考试的题型安排。正确的做题顺序可以帮助考生更加有效的完成题目。雅思学术类阅读现在官网上分为十大题型：Multiple Choice;Short-answer questions;Sentence Completion;Notes, Summary or Table/Flow-chart Completion;Labelling a Diagram;Headings;Locating Information;Identification of Writer’s Views/Claims or of Information in a Text;Classification;Matching。这些题型绝大多数题目是细节型的题。一般来说，建议考生按照从大意题到细节题的做题顺序完成整篇试题。也就是说，在考试过程中，如果考生遇到“Headings”这种标准的大意题，当然是需要最先完成的。而其他细节题在考生对于文章大意有所了解的前提下去完成会很容易定位。在此需要特别说明的是最近很流行的细节配对题，一般建议考生安排在其他题目完成之后再去完成，这样考生对于文章的结构和各段的大意都有比较清晰的了解，在这个基础上再去完成细节配对题会节约很多定位的时间，而且正确率也会有所提升。
最后要提醒即将考试的“烤鸭”们的就是信心和情绪。良好的心理素质是在考场上正常发挥水平的重要保证。长期辛苦的备考之后，考生们有理由相信自己会在考场上取得满意的成绩。适当的自信也是阅读速度和解题正确率的保证。另外，有些考生如果碰到的文章是自己不熟悉的领域或不熟悉的题型就会大受“打击”，影响做题情绪。这个是完全没有必要的。要明白有时候文章当中那些生词往往根本不会影响考生做题，属于我们上文所提及的次要信息。所以千万不要让那些次要的内容影响了做题目的情绪，否则就是得不偿失了。
雅思阅读模拟练习及答案
From The Economist print edition
How shops can exploit people’s herd mentality to increase sales
1. A TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (that is， how ants， bees or any social animal， including humans， behave in a crowd) can be used to influence what people buy.
2. At a recent conference on the simulation of adaptive behaviour in Rome， Zeeshan-ul-hassan Usmani， a computer scientist from the Florida Institute of Technology， described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted： for instance， by placing everyday items such as milk and eggs at the back of the store， forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes， also of the Florida Institute of Technology， set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that， if a certain product is seen to be popular， shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying.
3. Enter smart-cart technology. In Mr Usmani’s supermarket every product has a radio frequency identification tag， a sort of barcode that uses radio waves to transmit information， and every trolley has a scanner that reads this information and relays it to a central computer. As a customer walks past a shelf of goods， a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high， he is more likely to select it too.
4. Mr Usmani’s “swarm-moves” model appeals to supermarkets because it increases sales without the need to give people discounts. And it gives shoppers the satisfaction of knowing that they bought the “right” product—that is， the one everyone else bought. The model has not yet been tested widely in the real world， mainly because radio frequency identification technology is new and has only been installed experimentally in some supermarkets. But Mr Usmani says that both Wal-Mart in America and Tesco in Britain are interested in his work， and testing will get under way in the spring.
5. Another recent study on the power of social influence indicates that sales could， indeed， be boosted in this way. Matthew Salganik of Columbia University in New York and his colleagues have described creating an artificial music market in which some 14，000 people downloaded previously unknown songs. The researchers found that when people could see the songs ranked by how many times they had been downloaded， they followed the crowd. When the songs were not ordered by rank， but the number of times they had been downloaded was displayed， the effect of social influence was still there but was less pronounced. People thus follow the herd when it is easy for them to do so.
6. In Japan a chain of convenience shops called RanKing RanQueen has been ordering its products according to sales data from department stores and research companies. The shops sell only the most popular items in each product category， and the rankings are updated weekly. Icosystem， a company in Cambridge， Massachusetts， also aims to exploit knowledge of social networking to improve sales.
7. And the psychology that works in physical stores is just as potent on the internet. Online retailers such as Amazon are adept at telling shoppers which products are popular with like-minded consumers. Even in the privacy of your home， you can still be part of the swarm.

雅思阅读模拟练习及答案
Rogue theory of smell gets a boost
1. A controversial theory of how we smell， which claims that our fine sense of odour depends on quantum mechanics， has been given the thumbs up by a team of physicists.
2. Calculations by researchers at University College London (UCL) show that the idea that we smell odour molecules by sensing their molecular vibrations makes sense in terms of the physics involved.
3. That’s still some way from proving that the theory， proposed in the mid-1990s by biophysicist Luca Turin， is correct. But it should make other scientists take the idea more seriously.
4. “This is a big step forward，” says Turin， who has now set up his own perfume company Flexitral in Virginia. He says that since he published his theory， “it has been ignored rather than criticized.”
5. Most scientists have assumed that our sense of smell depends on receptors in the nose detecting the shape of incoming molecules， which triggers a signal to the brain. This molecular ’lock and key’ process is thought to lie behind a wide range of the body’s detection systems： it is how some parts of the immune system recognise invaders， for example， and how the tongue recognizes some tastes.
6. But Turin argued that smell doesn’t seem to fit this picture very well. Molecules that look almost identical can smell very different — such as alcohols， which smell like spirits， and thiols， which smell like rotten eggs. And molecules with very different structures can smell similar. Most strikingly， some molecules can smell different — to animals， if not necessarily to humans — simply because they contain different isotopes (atoms that are chemically identical but have a different mass)。
7. Turin’s explanation for these smelly facts invokes the idea that the smell signal in olfactory receptor proteins is triggered not by an odour molecule’s shape， but by its vibrations， which can enourage an electron to jump between two parts of the receptor in a quantum-mechanical process called tunnelling. This electron movement could initiate the smell signal being sent to the brain.
8. This would explain why isotopes can smell different： their vibration frequencies are changed if the atoms are heavier. Turin’s mechanism， says Marshall Stoneham of the UCL team， is more like swipe-card identification than a key fitting a lock.
9. Vibration-assisted electron tunnelling can undoubtedly occur — it is used in an experimental technique for measuring molecular vibrations. “The question is whether this is possible in the nose，” says Stoneham’s colleague， Andrew Horsfield.
10. Stoneham says that when he first heard about Turin’s idea， while Turin was himself based at UCL， “I didn’t believe it”。 But， he adds， “because it was an interesting idea， I thought I should prove it couldn’t work. I did some simple calculations， and only then began to feel Luca could be right.” Now Stoneham and his co-workers have done the job more thoroughly， in a paper soon to be published in Physical Review Letters.
11. The UCL team calculated the rates of electron hopping in a nose receptor that has an odorant molecule bound to it. This rate depends on various properties of the biomolecular system that are not known， but the researchers could estimate these parameters based on typical values for molecules of this sort.
12. The key issue is whether the hopping rate with the odorant in place is significantly greater than that without it. The calculations show that it is — which means that odour identification in this way seems theoretically possible.
13. But Horsfield stresses that that’s different from a proof of Turin’s idea. “So far things look plausible， but we need proper experimental verification. We’re beginning to think about what experiments could be performed.”
14. Meanwhile， Turin is pressing ahead with his hypothesis. “At Flexitral we have been designing odorants exclusively on the basis of their computed vibrations，” he says. “Our success rate at odorant discovery is two orders of magnitude better than the competition.” At the very least， he is putting his money where his nose is.
Questions 1-4
Do the following statements agree with the information given in the passage? Please write
TRUE if the statement agrees with the writer
FALSE if the statement does not agree with the writer
NOT GIVEN if there is no information about this in the passage
1. The result of the study at UCL agrees with Turin’s theory.
2. The study at UCL could conclusively prove what Luca Turin has hypothesized.
3. Turin left his post at UCL and started his own business because his theory was ignored.
4. The molecules of alcohols and those of thiols look alike.
Questions 5-9
Complete the sentences below with words from the passage. Use NO MORE THAN THREE WORDS for each answer.
5. The hypothesis that we smell by sensing the molecular vibration was made by ______.
6. Turin’s company is based in ______.
7. Most scientists believed that our nose works in the same way as our ______.
8. Different isotopes can smell different when ______ weigh differently.
9. According to Audrew Horsfield， it is still to be proved that ______ could really occur in human nose.
Question 10-12
Answer the questions below using NO MORE THAN THREE WORDS from the passage for each answer.
10. What’s the name of the researcher who collaborated with Stoneham?
11. What is the next step of the UCL team’s study?
12. What is the theoretical basis in designing odorants in Turin’s company?
Answer Keys and Explanations
1. T 见第一段。“give sth the thumbs up”为“接受“的意思。
2. F 见第三段。 “That’s still some way from proving that the theory， proposed in the mid- 1990s by biophysicist Luca Turin， is correct.”意即“现在尚无法证实生物物理学家Luca在九十年代中期提出的理论是否正确。”
3. NG
4. T 见第六段 “Molecules that look almost identical can smell very different — such as alcohols， which smell like spirits， and thiols， which smell like rotten eggs.”“identical” 一词是“完全相同”的意思。这句话是说alcohols和thiols的分子结构看起来一样，但是它们的味道却相去甚远。
5. Luca Turin 文章第二，三和七段均可看出Luca的理论即人类的鼻子是通过感觉气味分子的震动来分辨气味的。
6. Virginia 见第四段。
7. tongue 见第五段 “This molecular ’lock and key’ process is thought to lie behind a wide range of the body’s detection systems： it is how some parts of the immune system recognise invaders， for example， and how the tongue recognizes some tastes.”
8. the atoms 见第八段 “This would explain why isotopes can smell different： their vibration frequencies are changed if the atoms are heavier.”
9. vibration-assisted electron tunneling 见第九段 ““The question is whether this is possible in the nose，” says Stoneham’s colleague， Andrew Horsfield.” 句中的代词“this”指句首的“vibration-assisted electron tunneling”。
10. Andrew Horsfield 见第九段结尾。
11.proper experimental verification 见第十三段。
12.their computed vibrations 见第十四段
篇6：GRE写作考试如何合理分配时间
GRE写作考试3阶段时间分配达成目标完整攻略 高分作文写法系统讲解
第一步：审题、确定立场、列出理由
最少3分钟最多5分钟。
要避免两个极端：
a.用时太少，理由没有想清楚就开始写，不仅造成文章逻辑结构不清，还会引起行文中频繁地修正，欲速则不达;
b.用时太多，不要追求一次思考就能把每一条理由及相关例证都想出来。其实想出两条之后就可以动笔，各个理由的例证可以写到该段时边思考边写。这一点你不必怀疑，只要你的思维还是正常的，一定能做到。
第二步：正文写作最少22分钟最多26分钟
a.各段写作时，注意对段落的不同部分给予不同的重视。主题句给予最大重视，注意炼句，别说你不想写主题句，主题句可以使读者和笔者本人更清晰该段落写什么。各段中支持性细节写作不必遵循相同的模式。
有n种选择可供参考：1.举具体事例;2.说对方相对缺点;3.使用数据;4.使用假想例子;5.使用类比、比喻、引用等修辞手段来论述。哪一种你最容易想出来，就用哪一种。
b.考前将文章开头、结尾、例证、让步等各种句型背熟练，并且练习和模考时把他们用熟。别试图在考场上再去临时决定比如哪种开头好，怎样结尾好。使用自己选中的套路。
c.当写作考试还有5分钟结束时，一般你应该已经写到最后一条理由，或者已经在做结尾。要确保文章有结尾段。
第三步：检查需要1-3分钟，有侧重点地检查
a.句法：确保每句话是完整的，有谓语，且简单句只有一个谓语。
b.时态：文章绝大部分使用的是一般现在时;一般现在时第三人称要使用单数;使用过去发生的事例时用的是过去时;c.主谓一致按此三步，持续练习5篇以上，可以确保时间问题。

GRE issue写作优秀实例：实用的意义
题目：
Practicality is now our great idol, which all powers and talents must serve.Anything that is not obviously practical has little value in today's world.
正文：
In today’s society idealism seems to become an ideology that is marginalized and practicality is our great idol, thus, the speaker asserts that anything that is not practical bears little value. I admit that being practical is the wide-accepted dogma in order to survive in this world, but by going too far to claim that anything that is not practical has little value is against the empirical observation as well as the general stimulus that push the human society forward.
Admittedly, practicality has become a cult in today’s society. Too often do we hear people talk about being practical whenever they come to make important decisions or choose between several alternatives. The deep-rooted cause underlying this phenomenon is that with the development of modern society, the emphasis is placed more on financial gaining, quick fame, sensible choice and so forth. Our society is rather stable compared with that of the last century when war, violence, human right movements has become the symbol of that period. People are enjoying this peaceful environment with less crucial missions rested upon them and as a result, they shift from idealism to struggle for the common well being of mankind to the practical concept of individual achievement.
This ideology has its merits since after all the disaster and upheaval that our human race has undergone, it is judicious to focus on the economic aspect of things in order to tackle the most important social problems such as poverty, hunger and environmental problems which all deserve us to sit down and work out practical solutions. On the personal level, being practical is how a person would possibly succeed in his career or personal life. One is likely to make sensible decisions for his education and job choice on the basis of practical consideration of his own strength and weakness and careful analysis of the prospect of research direction and job market. Even those in power and intellects need to consider practically since hasty decision built upon pure ideal meditation would hardly find its way in the modern society and is doom to failure.
Agreeing with the speaker that practicality has become the great idol in our society, I am strongly against his point that anything that is not practical has little value. Even in today’s society, idealism is by no means relegated to the place of total neglect and disregard. For one thing, in history, so much achievement is the outcome of several generations’ struggle such as fighting for equality for women, human rights movement,etc. In today’s society, practicality is the way we can obtain our goal but idealism offers the philosophical explanation of why we should set this as our goal and the clear the ultimate value of our pursuing. What is more, by totally fixed one's eyes upon the practical aspect of things, we face the danger of neglecting one important part of our pursuit, that is the mental enjoyment brought out by idealism. If we have a clear goal set in mind and put practical endeavor at the same time, the result would be more satisfactory and valuable.
To sum up, I agree with the speaker insofar as the wide acceptance of practicality is considered. Being practical is the tenet of modern society and it does shed light on the wise way of doing things and obtaining goals, no matter in the personal or social level.But the speaker goes too far by claiming that it is the only valuable ideology in society.I am strongly against this idea since in history or at present, we human beings still need the philosophical explanation to clear our goal and to provide motivation. In this aspect, idealism would never be replaced with pure practical consideration. Otherwise,human society will be replete with insensible people directed by economic profit and quick fame and recognition.
GRE 写作优秀实例：想法付诸行动的困难性
题目：
It is easy to welcome innovation and accept new ideas. What most people find difficult, however, is accepting the way these new ideas are put into practice.
拥护革新和接受新想法很简单。但是在大多数人们看来，最困难的是接受把这些新想法付诸实现的方式。
正文：
The writer of the issue connotates an ironic phenomenon: though innovation is required in our era and eulogized by most people, application of it is clannished vehemently because of the fear of failure and the possibility of obtained possession and tradition impairing. The author grasps the paradox psychology of most people and pertinently reveals a universal mentality.
As is known that innovation may bring big progress and result in even a revolutionary transition of a society: the elevated efficiency of work, the ameliorated life, the enticing fruit of new technology and so on. Following with innovation of the second industrial revolution, great changes took place and immediately a renewed world unfolded before us with the application of its fruits. Seeing unimaginable profits and the magic power, who (including the society and government) can suppress their agitating desire to restrict development of innovation?
Unfortunately, innovation doesn't always follow the people's will and always acts like an uncontroled horse running in the plain. Worrying about the side-effect, people have to hold their desire back but admire those who are brave enough to taste crabs for the first time. Not everyone possesses the same courage as Biil Gate's, who dare invest on a fresh field and give up the chance of studying in Harvard University, which is the dream of most aggressive young people. Often, pondering what they have already possessed with what they might get from innovation, most people prefer the former to the latter, even content to sacrifice the latter to ensure the integer of the former. For example, a department may enroll those who are not very deft in the work but behave complaisant before higher-ups and deny to those who stick to their innovational opinion obstinately. After all, it is required more to cooperate with others harmoniously and conform to the traditional rules nowadays than to creat a new law according to individual penchant, in any company and corporation.
Maybe, some one argues that, how to cultivate innovation if personality should abdicate to interests of collective? Does the statement above alludes that employees should do nothing but keep silent and follow what the higher-ups dictated, strangling their inspiration to accord to the criterion today? No doubt, such supposition is rediculous. I mean that employees should try to approach their original though to tenet of the collective, not attempt to disobey the existed norm, respect suggestion and supposition of others and circumspect the innovation and then discuss with all the members in the company. That is, responsibility should be taken before the innovation is applied to practice.
Of course, many people don't have the ability that controling their compulsion of carrying their innovation into application. It doesn't lack of people who dare not apply innovation, and people who hold innovational thought are not scarc either, however,those who possess both of the two abilities and are lucky enough to encounter a proper opportunity to release their innovation is very few. The seperation of spirit of application and creation of innovation is the root of the the strange phenomenon, that innovation and new ideas are here and there while the acceptance and combination of them with application is too little to be heard
