动词不定式是初中英语的语法重点之一，也是每年中考英语试题的考点之一。它是动词的一种非谓语情势，没有人称和数的变化，不能单独作句子的谓语。其构成情势为＂to+动词原形＂，to为动词不定式的符号，本身无意义。动词不定式具有两大特点： 1.具有动词的特点，是以，后面可以跟表语、宾语或状语，构成动词不定式短语。2.具出名词、形容词或副词的特点，可以在句子中用作主语、宾语、宾语补足语、状语、定语、表语及同位语等。根据新课标八年级要求介绍近几年全国部分省市的中考英语试题为例，对不定式的难点以及它在中考英语中的考查点，作一简要的总结八年级英语下册总结和分析，供同学们学习时参考。
一、动词不定式作主语
1. It's our duty _________ the room every day.
A. to clean
B. cleaned
C. clean
D. cleans(甘肃省)
2. It's hard for us _________ English well.
A. learn
B. learns
C. to learn
D. learning(江西省)
3.建造这座立交桥将花费工人们一年多的时间。
It will _________ the workers over a year _________ _________ the flyover.(BeiJing市海淀区)
4. It's very nice _________ you to get me two tickets _________ the World Cup.
A. for， of
B. of， for
C. to， for
D. of， to(安徽省)
Keys： 1. A 2. C 3. take， to， build 4. B
［简析］动词不定式作主语时，可以直接放在谓语动词前面的主语位置，也可以用先行词it作情势主语，而将真正的主语(不定式)置于后面。常见的句式有：
(1)It is +形容词(of sb)to do sth.
⑵It is +名词(for sb)to do sth
.⑶It takes sb some time to do sth
.⑷It is +形容词(for sb)to do sth.句式
(1)中常用nice，kind，clever，good，right，wrong，foolish，careless等形容词，与前置词of搭配，这些形容词常表述不定式逻辑主语的属性或性质；句式⑷中常用hard，difficult，easy，important等形容词，与前置词for搭配，暗示不定式暗示的动作、举动的性质。
注意：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. 百闻不比一见。(错)It is to believe to see.
It's for sb.和It's of sb.
1) for sb.常用于暗示物质的特征特点，暗示客观情势的形容词，如easy, hard, difficult, interesting, impossible等：
It's very hard for him to study two languages.对他来讲学两门外语是很难的。
2) of sb的句型一般用暗示人物的性格，道德，暗示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。
It's very nice of you to help me.你来帮助我，你真是八年级下册英语语法太好了。
for与of的辨别要领：用前置词后面的代词作主语，用前置词前边的形容词作表语，造个句子。如果道理上通顺用of，欠亨则用for。如：You are nice. (通顺，所以应用of)。He is hard. (人是困难的，欠亨，是以应用for。)
is right to stop killing wild animals.
is the best time to visit USA in summer.
is helpful for us to learn English well.

但是to不成省略。这类用法常见于＂be glad to＂，＂would like (love) to＂，＂have to＂等布局中。
10、另外注意1）、带双宾语的及物动词，如：give …Sth.. to Sb ,.send….. to .bring….. to take….. to teach….. to want….. to.. lend…. to… ,show ....to ...etc to可以作前置词用+人/物/地点,大部分带双宾语的动词是接 to +Sb（间接宾语），而cook /buy read Sth for + Sb (见Module 10 课本１７９)Sb
注意：V +Sth +prep +Sb =V +Sb +Sth(指人的间接宾语在直接宾语前，要省略前置词to ) ．
E. g :Please you lend your pen to me .
= Please you lend me your pen.
请你借笔给我．
( ) you __________ Certainly. your pen to me your pen from me me your pen.谜底:C双宾语把指人的间接宾语提前,省略“to”，是lend是借进之意。
（）二、I cook my family ______ dinner. A. for B. to C./ 谜底：A。除了 ,read 外，其余大部分动词接双宾语是+ to（见课本178页）。
2）、另外还要注意一些词+V-ING 作宾语。Enjoy,keep,mind,finish, ,countine

八年级英语动词不定式用法梳理 动词不定式是由“不定式符号to+动词原形”构成的一种非 谓语动词结构。有些动词不定式不带to，动词不定式可以作 句子的主语、表语、宾语、定语、补语、状语或单独使用。不定式保留动词的某些特性，可以有自己的宾语、状语等。动词不定式和它后面的宾语、状语等一起构成短语，叫作不定式短语。 一、用作主语 多数情况用it作形式主语，把真正的主语一一动词不定式置于句末，特别是不定式短语较长时。动词不定式作主语，谓 语动词用第三人称单数形式。疑问词+不定式短语作主语可 置于句首，复合不定式结构作主语常置于句末。如： 1.1 t is our duty to try our best to deal With these problems. 2. The head teacher Said it WaS necessary to talk With his mother. 3. HOW to learn EngIiSh well is important. 4. To See iS to believe.（眼见为实；百闻不如一见） 二、用作表语 动词不定式作表语，常说明主语的内容、性质、特征。如： 1. The best Way is to join an EngIiSh club. 2. The first thing is to IiSten to the teacher carefully. 三、用作宾语 1. 可以接带to的
动词不定式作宾语的动词主要有：要求选择 同意(ask, choose, agree)期望决定学习(expect, hope, decide, Iearm，宁可假装知道(prefer, pretend, know)，希望想要愿意(wish, want, would like / love)。女口： 1) We decided to talk to SOme StudentS about Why they go there. 2) He PreferS to eat White bread and rice. 3) Id love to ViSit Mexico. 2. 动词decide, know, learn, show, teach, tell...，介词结构on... 可用疑问词带to的不定式短语作宾语，但Why后面的不定 式不带to。女口： 1) Could you PIeaSe tell me Where to Park my car? 2) It gives advice on What to do in lots of different SitUations. 3. 动词feel, find, make, think等后面，可以用it作形式宾语 代替真正的宾语--- 动词不定式，句子结构是…feel / find / make / ... it+adj. / n.+to do...。女口: 4. 感知动词like, love, know等一般不用进行时态。 5. 后接动词不定式或Ving形式作宾语，意思差别较大的动词有forget, remember等。后接不定式作宾语，表动作尚未发 生；后接Ving形式作宾语，表动作已经发生。stop to do停

(2)It is +名词(for sb)to do sth (3)It takes sb some time to do sth (4)It is +形容词(for sb)to do sth.句式 注意：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.百闻不如一见。(错)It is to believe to see. It's for sb.和It's of sb. 1) for sb. 常用于表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult,interesting, impossible等： It's very hard for him to study two languages. 对他来说学两门外语是很难的。 2) of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。 It's very nice of you to help me. 你来帮助我，你真是太好了。 （二）、动词不定式作宾语 1.

He found it very difficult ______. 常接不定式作宾语的动词;want，like，agree，hope，wish，learn，begin，start，seem，decide，hate，choose，forget，remember等动词后面，可以接不定式作宾语。如果其后接形容词补足语时，则可以用it作形式宾语，而把作真正宾语的不定式放到后面 Sb + V + it （形式宾语）+ agj （形容词）+to+ V（宾语）注意无BE动词。 (三)、动词不定式作宾语补足语 Mr Li often teaches his Japanese friends to cook Chinese food.

A.Sb\Sth +be\ V+ so + adj\adv (a\an+adj +n)+that + can't\couldn't......... = Sb\Sth +be\ V+ too+adj\adv(for+Sb\Sth)+to+V ...... .....如此......以致....=太而.....不能.....

初中英语情态动词详细用法归纳（含练习及答案） 1. can 的用法： （1）.表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力.如：She can swim fast, but I can’t . 她能游得很快，但我不能。 I can see with my eyes. 我用眼睛看。could是can的过去式。表示过去的能力。 be able to do sth. 常常指经过努力，花费了时间和劳力之后才能做到某事。is/am/are able to do sth was/were able to do sth. （2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。 （3）.表示推测，可能性，意为“可能”，常用于否定句和疑问句中，此时can’t 译为“ 不可能”。如：Can the news be true? 这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wall.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there. —No. She __be there, I have just been there. A.can’t B.mustn’t C.needn’t D.wouldn’t 【解析】根据下文“我刚去过那儿”可知，应为“ 不可能”，can’t 表示推测[答案] A could的用法： （1）.can的过去式，意为“ 能、会”，表示过去的能力。如：He could write poems when he was 10. 他十岁时就会写诗。 （2）. could在疑问句中，表示委婉的语气，此时could 没有过去式的意思。如:Could you give me a hand? 你能帮我个忙吗？—Could I use your pen? 我能用一下你的钢笔吗? —Yes, you can.可以。（用could问，不能用could答。） 2. may的用法： （1）.表示请求、许可，比can 正式，如：May I borrow your bike? 我可以借你的自行车吗？You may go home now. 现在你可以回家了。 【例题】—_______ I borrow your MP3? —Sure . Here you are. A. May B.Should C.Must D. Would 【解析】在此处表示请求，意为“ 做……可以吗”。答案：A (2) .表示推测，谈论可能性，意为“ 可能，或许”，一般用于肯定句中。如：It may rain tomorrow . 明天可能会下雨。She may be at home. 她可能在家呢. may not 翻译为“可能不” (3) .may的过去式为might ，表示推测时。可能性低于may。如：He is away from school. He might be sick. 他离开学校了，可能是他生病了。 (4) . 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V 例如：May you have a good time. 祝你过得愉快。May you be happy! 祝你幸福！May you succeed！祝你成功！ 3. must的用法： (1).must 表示主观看法，意为“必须、一定”。如：You must stay here until I come back.在我回来之前你必须呆在这儿。Must I finish my homework right now? 我必须现在交作业吗？(must引导的疑问句) 肯定回答：yes ,you must. 否定回答：No, you needn’t/ don’t have to (2) 其否定形式mustn’t表示“ 一定不要” “千万别” “禁止, 不许”. 如：You mustn’t play with fire. 你不许玩火。You mustn’t be late. 你一定不要迟到。 (3)must表示有把握的推测，用于肯定句,指百分百肯定。如: The light is on, so he must be at home now.灯亮着，他现在肯定在家。 （4）①must 和have to 都有”必须”的含义，但侧重点不同： must强调说话者主观(自己）的看法。 have to强调客观（外力作用）的需要，也可以翻译为“不得不”。

B ［简析］动词不定式作主语时，可以直接放在谓语动词前面的主语位置，也可以用先行词it作情势主语，而将真正的主语(不定式)置于后面。常见的句式有： (1)It is +形容词(of sb)to do sth. ⑵It is +名词(for sb)to do sth .⑶It takes sb some time to do sth .⑷It is +形容词(for sb)to do sth.句式 (1)中常用nice，kind，clever，good，right，wrong，foolish，careless等形容词，与前置词of搭配，这些形容词常表述不定式逻辑主语的属性或性质；句式⑷中常用hard，difficult，easy，important等形容词，与前置词for搭配，暗示不定式暗示的动作、举动的性质。 注意：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. 百闻不比一见。(错)It is to believe to see. It's for sb.和It's of sb. 1) for sb.常用于暗示物质的特征特点，暗示客观情势的形容词，如easy, hard, difficult, interesting, impossible 等： It's very hard for him to study two languages.对他来讲学两门外语是很难的。 2) of sb的句型一般用暗示人物的性格，道德，暗示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。 It's very nice of you to help me.你来帮助我，你真是八年级下册英语语法太好了。 for与of的辨别要领：用前置词后面的代词作主语，用前置词前边的形容词作表语，造个句子。如果道理上通顺用of，欠亨则用for。如：You are nice. (通顺，所以应用of)。He is hard. (人是困难的，欠亨，是以应用for。) A.It is right to stop killing wild animals. B.It is the best time to visit USA in summer. C.It is helpful for us to learn English well. 二、动词不定式作宾语
初中英语情态动词详细用法归纳（含练习及答案）（直接打印版） 情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。 1. can 的用法： （1）.表示能力、许可、可能性。表示能力时一般译为―能、会‖，即有种能力，尤其是生来具备的能力，此时may 和must 均不可代替它。如：She can swim fast, but I can’t . 她能游得很快，但我不能。I can see with my eyes. 我用眼睛看。 （2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。 （3）.表示推测，意为―可能‖，常用于否定句和疑问句中，此时can’t 译为― 不可能‖。如：Can the news be true? 这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wall.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there. —No. She __be there, I have just been there.

动词不定式 一. 定义： 动词不定式是非谓语动词的一种，它没有人称和数的变化，在句子中不能独立作谓语，但它仍保持动词的特点，既可以有自己的宾语和状语。同时动词不定式又具有名词、形容词、副词的特征，在句中可以作主语、表语、宾语、宾语补足语、定语和状语。 二. 动词不定式的构成：to+动词原形 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。 We hope to get there before dark. 我们希望天黑以前到那儿。 The girl decided to do it herself. 那个姑娘决定自己做那件事。 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 I remember seeing you somewhere before. 我记得以前在哪儿见过你。 Please remember to turn off the light when you leave. 离开时请记得关好灯。 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）
