[重要点评]

1.答案选A。none是“没有任何人和物”,是回答how many 问句的;no one“没有人”

是回答who 问句的;nothing“没有任何东西”,是回答what问句的。

2.答案选B。“in/on/to + the+方位词+of+地点”结构中,in表示“在……境内”,on表示“接壤”,to表示“在……境外”。

3.答案选B。wish有“希望,想要”的意思。可接不定式作宾语或接复合宾语,而hope则不接复合宾语。句中you to come 是复合宾语。

4.答案选D。put on 是“穿上衣服”。wear是“穿着……衣服”,have 常与on 搭配,它们都以衣服名称作宾语;dress是“给……穿衣服”,常用“某人”作宾语。

5.答案选C。have sth done 词组是“让某事由别人做”的意思。have 用法较多,在这里用作使役动词。

6.答案选B。in the end 是“最后”的意思,可直接作状语;“by the end +of +时间/地点”表示“在……时间/地点的末端”。本题to the end与walk对应,表示“走到……尽头”。

7.答案选C。根据答语never,选择how often,表示动作或状态发生的频率;how soon 表示“多久以后”,一般用于对“in+一段时间”结构提问;How long 是“多久”,一般用for或 since引导的时间状语来回答;how much 表示“多少”,不用于回答时间。

8.答案选A。so 用于修饰形容词或副词,such用于修饰名词(词组)。本题中把beautiful从a beautiful song 词组中提前,用so修饰。

9.答案选C。 本题考查四个选项的用法区别。hear form=get a letter from,“收到某人来信”;hear of 和hear about是“听说”的意义,hear 是“听见”,如果用作“听说”,后面一般跟宾语从句。

10.答案选B。本题虽然没有否定词,但too…to 结构含有否定意义,仍然把该句视为否定句,nobody是否定的,不能再用。everybody 和somebody常用于肯定句中,所以只有anybody适合。

篇3:小品词 “to” 的用法

【高考走向】

小品词“to”是指分别用作不定式符号和介词的“to”。作为不定式符号,to后面接动词原形;作为介

词,to后面接名词、代词或动词的-ing形式。高考对to的考查通常出现在单项填空、短文改错和单词拼写

等题型中,主要包括以下几个方面的内容:

1.不定式符号to的用与不用;

2.to do与doing的区别;

3.对to属性的判断。即, 是to do, 还是to doing?

【典型例题】

1.(北京, 单项填空)

_______ some of this juice --- perhaps you'll like it.

A. Trying B. TryC. To try D. Have tried

正确答案:B 根据情景,题干的前一部分为一祈使句。祈使句要求以动词原形开头,所以选B。

2.(北京2000,短文改错)

I would like very much come but I have an examination on Monday morning.

正确答案:在come前面加to。would like后面必须接带to的不定式。

3.(NMET99,单项填空)

The purpose of new technologies is to make life easier, _______ it more difficult..

A. not make B. not to make C. not making D. do not make

正确答案:B 题干部分已有to make life easier作表语,所以选B,表示对比。

permit, tell, want, warn, wish, should like/love, would like/love, etc..

4.需要接不带to的不定式作宾补的动词,中学阶段有11个,必须牢记在心。它们是:see, notice,

observe, watch, look at, have, let, make, hear, listen to, feel

例如:I felt someone enter and then leave the room.

5.第4条中的11个动词如果用于被动句,作主补的不定式必须加to (let有时有例外);

例如:He is made to do a lot of exercises by his parents every day.

6.祈使句中的动词,情态动词或助动词之后的动词,以及紧接在why和why not之后的动词都必须用原

形,不能加to;

例如:Why not go and ask the teacher for some advice?

Why don't you go and ask the teacher for some advice?

7.在had better/best, would rather/sooner, would rather/sooner ... than, cannot

(help/choose) but, do nothing but, have nothing to do but等结构后面必须接动词原形,不能加to;

例如:Yesterday evening, I did nothing/had nothing to do but watch TV.

比较:I had no choice but to wait for Mother outside the house, for I had lost the key.

8.go on, stop, remember, forget, regret, try等动词后面接to do和doing意思不同;

例如:--- I tried to persuade him but failed.

---Why not try talking with his parents?

9.to do作状语主要表目的、结果、原因(用于形容词之后)等;doing作状语主要表方式、原因、时

间等;

10.通常只接doing, 不接to do作宾语的动词和习语主要有admit, advise, appreciate, avoid,

be busy, be worth, can't help, can't stand, consider, delay, enjoy, escape, excuse, finish,

forbid, give up, imagine, keep, mind, miss, pardon, permit, practise, put off, suggest,

etc..

例如:The teacher suggested (our) going there on foot.

=The teacher suggested that we (should) go there on foot.

11.包含介词to的短语动词常用的有be/become/get used to, devote ... to, get down to,

look forward to, lead to, stick to, listen to, prefer ... to, 等。(这种结构并不一定都可以接

动词的-ing形式,但都可以接名词和代词作宾语。)

例如:I prefer staying at home watching TV to going to the cinema.

比较:I prefer to stay at home watching TV rather than go to the cinema.

12.口语中,不定式符号to有时单独使用,而省略其后的动词。如I'd love/like to, I used to, etc..

例如:He will go there if he is asked to.

---Will you go there with us?

---I prefer not to.

He says he will go if he has got a chance/the time (to).

once引导的是时间状语从句还是条件状语从句

once 用作连词,既可以表示“条件”(= if, as long as),也可以表示“时间”(=as soon as)。一般语法书,把它分别列入“引导条件从句”和“引导时间从句”的连词中。这需要具体语境具体判断,注意中文翻译。

下面援引词典中的例句,once 引导“条件从句”:

1. It isn't too difficult once you get the idea.

你一旦弄懂了,就不太难了。

来自柯林斯例句

2. You can't duck out once you've taken on a responsibility.

一旦承担起责任你就不能逃避。

来自柯林斯例句

3. It's easy, once you've got the knack.

你一旦掌握这个技能就容易了。

来自《权威词典》

4. Once you're stuck in deep snow, it's difficult to lever yourself out.

你一旦陷进深雪中, 那就很难出来。

来自《简明英汉词典》

5. Once you've given your word, don't try to back out.

一旦许下诺言, 就不要想翻悔。

来自《现代汉英综合大词典》

6. Once you begin you must continue.

你一旦开始,便不可停下来。

来自《现代英汉综合大词典》

7. Once we have promised, we should keep it.

一旦许下诺言,我们务必遵守。

8. We cannot move him from any decision once he has made it.

他一旦做出决定,我们就无法使他改变。

9. Remember, once you've signed the contract, there is no turning back.

记住,一旦签了合同,就不可能反悔了。

10. Once losing this chance,you can't easily find it.

一旦失去这次机会你就很难找回。

11. Once he is unemployed, he is done for.

他一旦失业就完蛋了。

来自《简明英汉词典》

12. Once he opens his mouth, he never stops.

他一旦打开话匣子就没个完。

来自《现代汉英综合大词典》

【重要说明】once 引导“条件从句”时,多用一般现在时,表示一种假设,未必实现。仔细体会上面的所有例句,即便含有“时间”概念,但表示“条件”的成分则更大!引导“时间从句”时,多为过去时,表示动作已经发生。例如:

He threw himself into work once he got back from his holidays. (= as soon as)他度假一回来就投身于工作。

二、词义辨析:还有“连接”意思的词还有哪些?

join, combine, unite, connect, link, attach, couple, associate, relate

这些动词均有“连接,结合,联合”之意。

join侧重把原来不相连接的物紧密地连接在一起,但仍可再分开。也指把分散的人或几个部分的人联合起来,或加入到某团体中去。

combine指两个或两个以上的人或物结合在一起。

unite指联合、团结、结合在一起,构成一个整体。

connect指两事物在某一点上相连接,但彼此又保持独立。

四、一起来玩个填词游戏吧

英语口语每天学:量词系列:a couple

A couple到底是几个?

Strictly speaking, “a couple” means two.

e.g. a couple of pens: 两支笔

a couple of cups: 两个杯子

..常口语里,它也能指几个、多个

Let's get a couple of apples: 我们买几个苹果

具体的数量,还是要通过语境分析。

a few & a few of 一些?

注意语法:

A few___ 不是 a few of ___

量词通常都用“of”链接后面的名词,但“a few”是个例外(few同理)

“a few pens”, not “a few of pens”: 是 few pens,而不是a few of pens

例外:当 a few后面跟的不是具体事物时,要加of

比如:

a few of these

a few of those

a few of us

【英语词汇】 a couple of, a pair of 两个......, 一对......

a couple of 两(或几)个...

辨析: 意思广泛而模糊,既可指两个,也可指多个.指同类中的两个时, 不强调成对,也不构成一个整体,谓语动词一般用复数.

例: a couple of cars/days 两(或几)辆汽车/两(或几)天

I found a couple of boots in the bedroom but they don't make a pair.

我在卧室室找到了两只靴子,但它们不是一对.

a pair of 一对...,一双....

辨析: 指由同一种材料制成的两个配套的物体, 属于一个不可分割的整体,缺少其中之一则无法使用, 谓语动词用单数还是复数取决于这两者是一个整体还是两个事物或人的组合.

例: a pair of scissors/shoes/trousers 一把剪刀/一双鞋子/一条裤子

She is going to buy a pair of jeans. 她想买一条牛仔裤.

A good and protective pair of trainers is essential.

一双又好又具备保护性的跑鞋是必不可少的.

A pair of dancers are performing on the dance floor.一对舞伴正在舞池里表演.

【英语词汇】couple 和 pair的区别

1) pair指使用时彼此不能分开的两件东西构成的物品,这两件东西可以连在一起,也可以不连在一起,但缺一不可。

He is wearing a pair of glasses.他戴着一副眼镜。

How many pairs of shoes do you have? 你有多少双鞋?

注:a/every/this/that pair of something作主语,谓语动词用单数。

This pair of shoes fits me well.这双鞋我穿很合脚。

A pair of sunglasses is lying on the table.桌子上有一副太阳镜。

She felt as if every pair of eyes in the room was on her.她觉得房子里的每一双眼睛都在看她。

pair也可以指人,相当于couple指的是“同样立场、一起做同样事情或某种关联的两个人,作主语时谓语用复数。

注:a pair of somebody作主语,谓语动词用复数。

The pair were matched for age.这一对是按年龄配成的。

A pair of robbers were trying to kidnap his wife.两个强盗正试图绑架他的妻子。

The pair are looking for sponsorship from local businesses.两人正在寻找当地企业的赞助。

2) couple表示“两个相同的人或物(two things of the same kind)”,指人或物。指夫妻只能用couple,不能用pair。couple表示“夫妇,夫妻”且用作主语时,谓语动词可用单数(视为整体,尤其是当有each, every, only one等修饰时);也可以是复数(考虑其个体)。

The couple was/were married last week.这一对夫妇是上星期结的婚。

Each couple was asked to complete a form.要求每一对夫妇填一张表。

The couple is/are spending their honeymoon.那对新婚夫妇正在度蜜月。

The young couple are quarrelling with each other.这对年轻夫妻在吵架。(个体)

An old couple from Shanghai is moving in our apartment.一对老夫妇搬进了我们的公寓。(整体)

couple有时指“几个,两三个”,当couple作主语,此时表示复数意义,用作主语时,谓语动词要用复数。a couple of作主语谓语用复数。

He walked a couple of miles.他步行了好几里。

There are a couple of girls waiting for you.有两个女孩在等你。

There are a couple more files to read first.还有两份文件要先读。

篇7:英语语法目的状语引导词用法

一、in order that引导目的状语从句,that后面加从句。例如:

He studied hard in order that he could pass the exam. 他努力学习以便能考试及格。

在这里注意与in order to的区别,in order to+动词原形 ( in order to后面加的那个不叫目的状语从句,叫目的状语) 例如:

He got up early in order to take the first bus.

= He got up early in order that he could take the first bus.

他起床很早是为了赶上第一班 公共汽车

目的状语从句的一个特点:由于目的都是未来的行为,所以从句中一般用表示未来可能性时态,比如上面句中的could。当然还可以用will,would,can,等 。

二、so that既可引导目的状语从句,也可以引导结果状语从句。

Speak clearly so that they may understand you. 讲清楚些,以便他们能理解你。

1)其引导结果状语从句时,so that翻译为“以至于...”,经常可以和so/such...that...转换,且从句只能放在主句之后。例如:

He got up late so that he was late for school. = He got up so late that he was late for school.

他起晚了,所以他上学迟到了。

2)其引导目的状语从句时,从句只能放在主句之后,此时可以和in order that换用。例如:

He got up early so that he could take the first bus. = He got up early in order that he could take the first bus.

为了赶上第一班公交车,他很早起床了。

3)He came in quietly in order that he shouldn’t wake his wife. / He came in quietly in order not to wake his wife. 他轻轻进来,以免把他妻子吵醒。

三、对于目的状语从句的考查,多以单选和完形填空的形式,从连词的意义角度让大家选择连词。例如:

Ann listened carefully _____ she could discover what she needed.

A. such that B. in order that C. because D. even though

解析:题干的意思是“为了能够发现自己需要的东西,安认真听讲”。很明显从句表示的是目的。such that本身是错误短语,because 表示原因,even though是“尽管”的意思,不符合题意。答案:B

四、需要注意的易错点:如何区别目的状语从句中的so that与结果状语从句中的so that的用法,这是我们需要注意的。目的状语从句的so that是连着的,结果状语从句是分开的,即so…that. so that是目的状语从句,是为了什么什么,有目的的含义。而so…that是结果状语从句,是“如此怎么怎么样结果是什么”。例如:

I get up so early I can not be late

A. that B . so that C.such that D.in order

解析:题干的意思是“我起床如此早以便于我可以不迟到”。从句表示目的,首先排除C,因为such that本身是错误短语,在排除in order,因为它后面不能跟句子;因为句子中有so,所以大家可能选A,如果选它,那句子的意思是“我起床如此早结果我可以不迟到”,显然说不通,所以排除。答案: B
