  考点透视

  动词不定式具有名词、形容词和副词的特征,因此,在句中可以作主语、表语、宾语、宾语补足语、定语和状语。

  1.常跟不定式作宾语的动词有want(想、要),love(喜欢),begin(开始),need(需),learn(学会),agree(同意),decide(决定),hope(希望),start(开始),refuse(拒绝)等。

  I’m learning to skate on real ice. 我正在真正的冰上学滑冰。

  [特别提醒]

  (1)不定式短语作宾语时,如果还带有宾语补足语,通常用it作形式宾语,而被不定式短语放在宾语补足语之后。

  He found it very difficult to get to sleep. 他发现难以入睡。

  (2)begin(开始),start(开始),like(喜欢),hate(憎恨),love(喜爱)可以接动词不定式或-ing形式作宾语,意思一般没有区别。但like后接-ing形式指经常性的动作; 接不定式,指一时间、一次性的动作。

  I like having a twin sister. 我喜欢有个孪生姐妹。

  I like to have a twin sister. 我现在想有个孪生姐妹。

  (3)stop(停止),forget(忘记),remember(记得),try(试),go on(继续)等动词接不定式和-ing形式意义有区别。试比较:

  stop to do sth.停下来去做另一件事

  stop doing sth.停止(正在)做某事

  forget to do sth.忘记去做某事(还未做)

  forget doing sth.忘记做过某事(已经做)

  remember to do sth.记住去做某事(还未做)

  remember doing sth.记住曾做过某事

  try to do sth.试图要做某事

  try doing sth.试着做某事

  go on to do sth.接着做另一件事(已做完一件)

  go on doing sth.继续做(原来未做完的)某件事

  She stopped crying and listened to the music. = She stopped to listen to the music. 她停止哭闹,听音乐了。

  Don’t forget to tell him about it. = Remember to tell him about it. 别忘了(记住)告诉他这件事。

  I’ll try not to be late again. 我将争取不再迟到。

  She didn’t pull the door and tried pushing it. 她没有拉开门,便试着推一下。

  2.动词不定式常用作目的状语。

  He came to give us a talk yesterday. 他昨天来给我们作了个报告。

  Mrs Brown went to see her doctor. 布朗夫人去看她的医生。

  in order to 作“为了”解,用作目的状语。

  3.动词tell (叫,让),ask (请求), want(希望),order(命令),get(使),wish(希望),warn(警告),teach(教),invite(邀请)等动词后常跟不定式作宾语的补足语,构成tell/ask. sb. to do sth. “叫/请……某人做某事”句型。

  [特别提醒] 在被动语态句子中,不定式前必须加to。

  He was made to do it.他被迫做这件事。

  She was often heard to sing in the next room. 经常听到她在隔壁唱歌。

  4.不定式短语作定语须放在被修饰的词语之后。

  I have a lot of work to do. 我有许多事情要做。

  The doctor said he could do nothing to help him. 医生说他无能为力。

  5.不定式短语作主语时,常用it作形式主语,真正的主语不定式短语放在后面。

  6.作表语

  答案与分析

  1. A. tell sb. not to do sth.意为“叫某人不要干某事”,固定搭配。

  2. C. finish doing sth.意为“完成做某事”,是固定搭配。enjoy, finish, keep, feel like等后跟-ing形式作宾语。

  3. C. not...until...意为“直到……再/才”;had better的否定式是had better not do。

  4. A. let sb. do sth.意为“让某人做某事”。have a rest(休息)是固定词组。

  5. B. which指在某一定范围内选择;what则没有选择范围。

  6. B. would like to do sth.意为“想要做某事”,是固定句型。

  7. B. how to send an e-mail意为“怎样发电子邮件”。“疑问词+不定式”作宾语补足语。what to send(发送什么),与题意不符。

  8. B. 由句意判断。“戴奇形怪状的帽子是想让人们注意她”。

  9. A. make后跟不带to的不定式作宾语补足语。

  10. C. 用排除法。由would you like to do...; do you like to do... 可知A、B两项缺少小品词to。D项Do you不用I’d like to回答。

  11. A. ask sb. not to do sth.意思是“请某人不要做某事”。“她请他们不要乱丢东西”。

  12. C. seem to be作“似乎……;好像……”。look后不能跟不定式。

  13. D. prefer to do sth. rather than do sth.“宁愿……而不……”是一固定句型。注意,rather than后跟不带to的不定式。

  14. B. see, hear等后跟不带to的不定式作宾语补足语,但在被动语态中,see, hear等要跟带to的不定式作主语的补足语。

  15. C. hear, see等动词后可跟不带to的不定式或-ing形式作宾语补足语。跟不定式表示动作发生的全过程;跟-ing形式表示动作正在发生。由Listen!可知“婴儿正在哭”。

  16. C. do some reading(阅读)是固定搭配。又如do some cleaning, do some shopping, do some washing等。

  17. B. allow sb. to do sth.作“允许某人做某事”解,allow后跟不定式作宾语补足语。ask也有这种用法,但在这里不符合语境。

  18. C. 过去分词作后置定语,相当于定语从句which are taken by African boys。此题易误选A、B或D。三项均为被动语态。

  19. D. 不定式作目的状语。此题易受情态动词could的影响而误选A。题意是“我们的老师尽力(做她能够做到的)帮助我们学英语”。

  20. B. “疑问词+不定式”作宾语补足语。题意是“请告诉我哪里能够买到数码相机好吗?”

  21. B. be busy doing sth.= be busy with sth.意为“忙于做某事”。

  22. B. prefer sth. / doing sth ...to sth. / doing sth.(喜欢……而不喜欢……;更喜欢),表示两者中的比较。prefer to do sth. rather than do sth.也是常用句型之一。

  23. D. feel like后跟动词-ing形式作宾语,表示“想要做某事”。由I am feeling sick now.(我现在感觉不舒服)可知,“现在我不想吃东西”。

  24. D. repeat(重复;再说);review(回顾;复习);recite(背诵);report(汇报)。由I can’t hear you clearly(我听不清楚你的话)可知是要请你“再说一遍”。

  25. D. keep doing sth.(一直做某事)。题意是“不管有多大困难,我一直坚持试验到成功”。failing符合语法,但不符合句意。

  26. B. “too + adj. + to do sth.”表示“太……不能……”。题意是“上个学期那孩子太忙,没能给她父亲写信”。此题易受be busy doing sth.的影响而误选C。

  27. B. Would/will mind doing ...?意为“请你……好吗(介意吗)?” 表示“不介意”一般说Of course not.或Certainly not.如果“介意”,则说Yes, I do.

  28. B. watch等动词后跟动词-ing形式作宾语补足语,表示动作正在发生。

  29. A. enjoy后跟动词的-ing形式作宾语。

  30. D. “动词+副词”构成的短语动词,如宾语是代词,则放在动词和副词之间;如宾语是名词,则放在两者之间或副词之后均可。
