动词不定式用法全解(含测试题及答案)
动词不定式用法全解英语动词的非谓语形式为三种：动词不定式、动名词和分词。
非谓语动词没有人称和数的变化。
动词不定式是一种非谓语动词形式，其结构为“to＋动词原形”，其中to不是介词，而是动词不定式的符号，称为小品词，动词不定式没有人称和数的变化。
动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、补足语、定语、状语等。
动词不定式的形式：第一部分动词不定式的时态一、动词不定式的时态：动词不定式不能在句中作谓语，尽管它本身有时态的变化，但是却不能靠自身的变化形式表示动作发生的具体时间。
动词不定式发生的时间，一般只能根据谓语动词的时间，产生相对的先后时间关系。
1．不定式的一般式，表示不定式的动作与谓语动词动作几乎同时发生，或在谓语动作之后发生，或者不强调不定式动作的时间性。
但不定式表原因时，往往先于谓语动作之前发生。
如：The news will not fail to surprise him.这个消息将不会不使他大吃一惊的。
（不定式动作在将来和谓语动作同时发生）I helped to repair the car.我帮助修理汽车。
（不定式动作在过去与谓语动作同时发生）He didn't know where to go.他不知道该去哪儿。
（不定式稍晚于谓语动作）Tell your brother not to come tomorrow.告诉你哥哥明天不要来。
（不定式晚于谓语动作）判断：He decided to sell his car.I tried to go to school in time.I hope to see you soon不定式表示谓语动作的原因时，往往发生在谓语动作之前。
如：I am very happy to see you here.She seemed surprised to meet us.（先是遇见我们，她然后很吃惊）2．不定式的完成式，通常表示动作发生在谓语动词之前。

初中英语动词不定式讲解试题和答案一、作主语，可以用it代替，it叫形式主语，动词不定式放在后面叫真正主语1．To learn a foreign language is not easy.It is not easy to learn a foreign language.2. It’s dangerous to drive very fast.二、作表语My idea is to ring him up at once. 我的想法是马上给他打电话。
如果主语部分含实义动词do，且作表语的动词又是“do”的内容，这时表语不定式的“to”可以省略。

（定语）The book ids too difficult for children to read. 这本书太难了，孩子们看不懂。
（结果状语）不定式复合结构作主语时，需注意：It’s + 形容词+ for / of + sb + to do sth.当上面的形容词指的是to do sth的性质时，用介词for。
It’s dangerous for children to swim in the river. 孩子在这条河里游泳很危险。

（你这个人粗心）十三、动词hear, see, feel, watch, notice, look at, listen to等后面的动词不定式作宾语补足语时不能带to, 即常见的形式为: hear sb do sth等Many people like to watch others play games. 许多人喜欢看别人玩游戏.十四、let, make, have后面的动词不定式作宾语补足语, 也不能带to; help后面的动词不定式作宾语补足语, to可有可无She let us meet her at the station, but she didn’t come. 她让我们去车站迎接她,卡她没有来.十五、十三和十四这两种情况下的动词不定式在改被动语态句子时,必须将省略的to还原,也就是说,动词后需跟带to的动词不定式.We heard him sing every day.He was heard to sing every day. 那时每天都听到他唱歌.十六、跟带to的动词不定式作宾语补足语的动词还有: ask, beg, leave, like, love, hate, prefer, order, teach, tell, believe, find, know, want, think, understand, would like等形式为: ask sb to do sthWould you like me to visit him? 要不要我拜访他?I would prefer you not to come tomorrow. 我宁愿你明天不要来.He ask the driver to stop the motobike. 他要那位司机拦下那辆摩托车.十七、区别下列词组的不同含义:①like to do sthlike doing sth②stop to do sthstop doing sth③remember to do sthremember doing sth④forget to do sthforget doing sth十八、It takes sb some time to do sth.花费某人一段时间干某事.It took me half an hour to do my homework yesterday.昨天我花了半小时做回家作业.It took Jim an hour and a half to read the book.吉姆花了一个半小时看这本书.It took mother one and a half hours to do the housework.母亲花了一个半小时干家务.用汉字表述上面的句型为:It + take + 人+ 一段时间+ to do sth.一段时间形式往往为像这样的例子:fifteen minutes15分钟,an hour一个小时, two days两天, half a month半个月,a year and a half一年半...等等十九、不定式的特殊句型too…to…①too…to太…以至于…He is too excited to speak.他太激动了，说不出话来。

②如在too前有否定词，则整个句子用否定词表达肯定，too 后那个词表达一种委婉含义，意为"不太"。
