【中考范例】
1. (2004年北京市海淀区中考试题)
---Do you know ________________?
---Only ten months old.
A. when does Tiger Woods start golfing
B. when did Tiger Woods start golfing
C. when Tiger Woods starts golfing
D. when Tiger Woods started golfing
【解析】答案：D。该题考查的是宾语从句的时态和语序。这个宾语从句的时态应用一般过去时，应为这里说的是过去的事情。语序应用陈述句的语序，所以正确答案是: when Tiger Woods started golfing。
2. (2004年北京市海淀区中考试题)
I’m interested in animals, so I _____________ every Saturday working in an animal hospital.
A. pay B. get C. take D. spend
【解析】答案：D。该题考查的是pay, get, take和spend这四个动词的用法区别。只有动词spend可以用在sb. spends time doing sth. 这个句型里，所以正确答案影视spend。
3. (2004年天津市中考试题)
Could I ________ your telephone? I have something important to tell my parents.
A. keep B. borrow C. use D. lend
【解析】答案：C。该题考查的是keep, borrow, use和lend四个动词的用法区别。keep的真正含义是“保留”，borrow的含义是“借入”，lend的含义是“借出”，只有use的含义是“使用”。在这个句子里实际上是“使用”的意思，所以应选use。
4. (2004年鄂州市中考试题)
---Hi, Ann. Where’s your brother? I need his help.
---He left home two weeks ago and _____away ever since.
A. is B. was C. has been D. had been

初三上册英语知识点
一. 定义：
由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。“动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。
二. 动词不定式的构成：to+动词原形
(1)作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。
如：To get there by bike will take us half an hour.
(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。
如：
It+be+名词+to do It's our duty to take good care of the old.
It takes sb+some time+to do How long did it take you to finish the work?
It+be+形容词+for sb+to do It is difficult for us to finish writing the composition in a quarter of an hour.
It+be+形容词+of sb+to do It is stupid of you to write down everything (that) the teacher says.
It seems(appears)+形容词+to do It seemed impossible to save money.
在句型中，常用表示客观情况的形容词，如：difficult，easy，hard，important，impossible，necessary 等;
在句型中，常用careless，clever，good，foolish，honest，kind，lazy，nice，right，silly，stupid，wise等 表示赞扬或批评的词。
在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is+形容词+to do句式 ，如：It's kind of you to help me with my English.=You are kind to helpme with my English.
(3)举例
(1) It's easy (for me) to do that.我做这事太容易了
easy, difficult, hard, important, possible, impossible, comfortable, necessary, better;
the first, the next, the last, the best, too much, too little, not enough
1、It's so nice to hear your voice.
听到你的声音真高兴。
2、It's necessary for you to lock the car when you do not use it.
当你不用车的时候，锁车是有必要的。
(2) It's very kind of him to help us. 他帮助我们，他真好。
Kind, nice, stupid, rude, clever, foolish, thoughtful, thoughtless, brave, considerate(考虑周到的), silly, selfish(自私的)
例句:
1、It was silly of us to believe him. 我们真愚蠢，竟然相信了他。
2、It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。
注意：
(1) 其他系动词如，look，appear等也可用于此句型
(2) 不定式作为句子成分时，动词用单数形式。
(3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型
(对)To see is to believe. 眼见为实。
(错)It is to believe to see.
三. 动词不定式作宾语
后面能接不定式作宾语的动词有：agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。
1、We hope to get there before dark. 我们希望天黑以前到那儿。
2、The man decided to do it herself. 那个男人决定自己做那件事。
动词不定式作宾语的注意事项(2点)
1. 有些动词既可跟不定式作宾语，也可跟动名词作宾语，但含义不同：
remember to do 记住要做某事
remember doing 记得曾经做过某事
forget to do忘记要做某事
forget doing 忘记曾经做过某事
stop to do 停下来去做某事
stop doing 停止做某事
go on to do 继续做另一件事
go on doing 继续做原来在做的事
2. 不定式作宾语时，如带有宾语补足语，则要把不定式放到后面，用it作形式宾语，构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。
如：He found it very difficult to get to sleep.他发现很难入睡。
四. 动词不定式作宾语补足语
1. 后面能接to不定式作宾语补足语的动词有：ask, order, teach, tell, want, wish, help等。
The teacher told us to do Exercise 1. 老师要我们做练习一。
I want both of you to go. 我要你们俩去。
We helped her (to) repair her bike. 我们帮助她修理自行车。
2. 使役动词let, have, make及感官动词see, watch, notice, hear, feel等要以不带to的不定式作宾补。
Let’s have a rest. 我们休息一会吧。
I saw him come in. 我看见他进来了。
感官动词后既可跟不带to的不定式作宾补，也可跟v-ing作宾补，前者表示动作的全部过程已结束;后者表示动作正在进行。
I saw him come downstairs.我看见他下了楼。(说明他下楼了这件事)
I saw him coming downstairs.我看见他在下楼。(说明他下楼时的情景)
五. 动词不定式作状语
Later he left home to work in different cities. 不久他离开家到不同的城市工作。
He went to see a football match. 他去看足球比赛了。
In order to catch the other students, I must work hard.
为了赶上其他同学，我必须努力学习。
六. 动词不定式作定语
不定式作定语一般放在所修饰的词的后面。
I need something to eat.
Do you have something to read?
Tom was so excited that he had no word to say.
He is really a fool only to eat.
The man to stand here just now is our English teacher.
The doctor had no way to save the patient.
注意：
(1)作定语的不定式是由及物动词组成，被修饰的名词或代词与不定式之间存在方位或方式关系需要有介词。
I am looking for a room to live in. 我正在找一间住房。(方位关系)
We have many things to do experiments with.
我们有许多做实验的东西(方式关系)
(2)作定语的不定式是由“be + adj + prep”构成的动词短语。
Here there isn’t any book for me to be interested in.
We have done many things to proud of. 我们做了许多引以自豪的事。
七. 动词不定式作主语
To give is better than to receive.
To reach there on foot is impossible.
动词不定式作主语时，可以用it 代替，把实际主语不定式放在后面。
It’s better to give than to receive.
It’s impossible to reach there on foot.
It’s + adj + for sb. to do sth.
It’s not difficult for me to study English well.
It’s easy for him to work out this math problem.
在这个句型中，如果形容词与不定式的逻辑主语关系密切，并且形容词用来说明逻辑主语的性质、品质、特点等，由of引出逻辑主语。这类形容词主要有nice, kind, good, wrong, right等。
八. 动词不定式和疑问词连用
动词不定式可以和疑问词what, which, how, where, when连用，构成不定式短语，可以作主语、宾语、表语、宾语补足语等。
How to do is still a question.
Have you decided when to leave?
九. 动词不定式的否定形式
动词不定式的否定式是在to前加not;不带to的不定式则在动词前加not. 如：
Zhang Ming asked me not to stay at home all day. 张明要我不要整天呆在家里。
My mother let me not do it by myself. 妈妈让我不要独自做这件事。
被动语态：
英语有两种语态：主动语态和被动语态
主动语态(The Active Voice)表示主语是动作的执行者。
被动语态(The Passive Voice)表示主语是动作的承受者。
构成：承受者+助动词be+及物动词的过去分词+by+执行者
一般现在时：承受者+助动词am / is/are +及物动词的过去分词+by+执行者
一般过去时：承受者+助动词was / were +及物动词的过去分词+by+执行者
承受者+助动词shall / will be+及物动词的过去分词+by+执行者
承受者+助动词 have/ has been+及物动词的过去分词+by+执行者
承受者+ can /may/must/should +be+及物动词的过去分词+by+执行者
被动语态用法：
1)当我们不知道动作的执行者是谁，或者没有必要指出动作的执行者时，需用被动语态。
2)当我们需要强调动作的承受者时,常用被动语态。
3)如果需要说出动作的执行者, 用by引导出动作的执行者。
主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。
主动语态变为被动语态时有以下几种情况：
1)主语+谓语动词+宾语
将主动语态的宾语变为被动语态的主语。
(主动)We bought a book yesterday.
(被动)The book was bought yesterday.
2)主语+谓语动词+间接宾语+直接宾语
将主动语态中一个宾语变为被动语态的主语。多数情况下将间接宾语变为主语。如果直接宾语变为主语时，间接宾语前要加介词to / for。
(主动)He showed me a book yesterday.
(被动)I was showed a book yesterday.
(被动)The book was showed to me yesterday.
3)主语+谓语动词+复合宾语
含有一个由宾语加宾语补足语构成的复合宾语，变为被动语态时，将主动语态的宾语变为被动语态的主语，宾语补足语保留不变，成为主语补足语。
(主动)I found him a good pupil. (宾语补足语)
(被动)He was found a good pupil. (主语补足语)
4)短语动词变为被动语态
有些短语动词相当于一个及物动词，其后可以接宾语，因此它们也有被动语态，但短语动词是不可分割的整体，变为被动语态时不可去掉其后面的介词或副词。
(主动)We should look after the patients very well.
(被动)The patients should be looked after very well by us.
5)宾语从句变为被动语态
若主动语态中是宾语从句，变为被动语态时常用it作形式主语，而把真正的主语放在后面。
It’s said that he passed the exam.
被动语态应注意的几个特殊问题：
(1)不及物动词带介词和介词宾语，在变为被动语态时，仍然要带上介词。
(主动)The students in class listen to the teacher carefully.
(被动)The teacher is listened to carefully by the students in class.
(2)当动词带有复合宾语时，并且宾补是省去“to”的动词不定式时，在被动语态中应加上“to”。
(主动)They make do all the work.
(被动)We were made to do all the work.
(主动)We often hear her sing English songs.
(被动)She is often heard to sing English songs.
(主动)I see him walk to school.
(被动)He is seen to walk to school.
初中英语怎么学才能提高
1、背诵单词、搭配。
单词是英语的一大基础，单词不过关，就别想学好英语了。常常看到有学生一个字母一个字母背背一个单词，或者在纸上把这个单词抄10遍。这样做即便记住了单词，也只是这一时，考试就忘了。而且，这种做法也只能记住几十个单词，单词多的话就不管用了。最好用的方法就是通过音标记单词，每个字母的发音其实就几种，只要熟练音标和字母在单词中常见的发音，那么当听到一个单词，基本上就能拼写下这个单词。即便是没有学过的单词，也能根据音标写个大概的模样。而至于要保证写对，海博老师建议，可以把每个单词做个小卡片，睡前翻一遍，连续几天就能掌握这些单词了。至于搭配，最好的办法就是放到句子里。比如说动词搭配，只要造一个简单的句子，多读几遍，就能记住了。英语中的一些搭配，其实就是一些不成文的规定。简单来说，就是固定出现，固定这么用，千万别去钻牛角尖。
2、背诵作文范例和典型句式。
找一些优秀的范文背诵，这一点相信每个学生都会做。但是，背诵范文，不是背诵内容，而是要了解句型和行文思路。所以，建议对每一篇作文都画一个流程图，了解思路，然后在流程图中，标明作文中用到比较好的句型，然后在自己写作的时候，尝试用上这些句型。但是，一定要充分了解这些句型的用法和意思，千万不要生搬硬套。
3、科学的学习方法。
首先是，劳逸结合。学习是一件费精力的事情，并不是花的时间越多越好，而是要学会恰当的放松与学习。你可以利用早上的时间学习英语、然后间接性休息，再学习其他的学科知识，交换着来，效果更好;
其次是，了解自己的弱项。每个人学习都会有不足的地方，所以，找到自己的初中英语语法弱项，针对性的练习与请教他人，才能更好的进步。
最后是，多动笔。俗话说：好记性不如烂笔头。只要把学到的知识试着多去运用，按照考试的标准去造句写文章，才能“下笔如有神”。
4、积极地英语学习心态。
学习是一件需要长久坚持的事情，不要三天打鱼两天晒网，然后还苦恼自己为什么一点效果都没有。
首先要摆正心态，正确认识学习英语的两面性。坚持学习并且善于运用，时间久了总是会有回报的。
然后，了解学习的枯燥但能够勇敢面对。学习不是娱乐，但可以把学习当成娱乐，可以学会做能让自己感兴趣的事情与学英语相关联，发现学英语的趣味性，学会放松自己，给自己减压，多与朋友同学交流沟通、或与老师交流问题。
