非谓语动词
知识导图
考点精讲
考点1动词不定式
动词不定式的基本结构为“(to+)动词原形”,否定形式为“not+(to+)动词原形”。其常见用法如下:
1.作主语
(1)置于句首,谓语动词用单数形式。如:
To save money now seems impossible.现在要省钱似乎是不可能的。
(2)为避免头重脚轻,通常用it作形式主语,而将动词不定式所表示的真正的主语放在句末,其常用结构为:
①It’s+adj.+(for/of sb.) to do sth.;
②It+is+n.+to do sth.;
③It takes sb.+some time+to do sth.;
④It seems/appears+adj.+to do sth.等。
如:In China,it is interesting to see people eating with chopsticks.在中国,看到人们用筷子吃饭是很有趣的。
It’s our duty to take good care of the old.照顾好老人是我们的责任。
2.作表语
构成“be to do”,表愿望、目的、责任、义务等。如:
The purpose was for the kids to understand their family history.目的是让孩子们了解他们的家族史。
3.作宾语
(1)一些表命令、打算、希望、决心等的动词后常接不定式作宾语。如:
Meredith never wanted to talk about these interests.梅雷迪思从不想谈论这些兴趣。
(2)find/think等后跟动词不定式作宾语时,常用it作形式宾语,而将真正的宾语放在句末。如:
He finds it easy to learn English well.他发现学好英语很容易。
常见的后接动词不定式作宾语的动词有:
afford负担得起 agree同意 begin/start开始
choose选择 decide决定 expect期望
fail没能够 forget忘记 help帮助
hope/wish希望 learn学习 manage设法完成
offer主动提出 plan计划 promise承诺
refuse拒绝 remember记得 want/would like想要
【易错点】两个并列的带to的不定式由and或or连接时,第二个不定式符号to常省略。如:
She has learned to read and write.她已经学会了读和写。
【方法技巧】
巧记不定式作宾语的动词
想要拒绝莫忘记(want,refuse,forget),
需要努力就学习(need,try,learn),
喜欢、同意加帮助(like,agree,help),
希望、决定后开始(hope/wish,decide,begin/start)。
4.作宾语补足语
(1)动词不定式作宾语补足语时与宾语有逻辑上的主谓关系。如:
He got his sister to help him with his homework.他让姐姐帮助他做家庭作业。
常见的后接动词不定式作宾语补足语的动词有:
advise建议 allow允许 ask要求
encourage鼓励 expect期望 force强迫
help帮助 invite邀请 order命令
persuade说服 teach教 tell告诉
want/would like想要 wish希望 warn警告
(2)一些使役动词和感官动词也用不定式作宾补,这时不定式要省略to。这些动词有:一感(feel)、二听(hear,listen to)、三让(let,make,have)、四看(look at,see,watch,notice)。如:
The boss made the workers rest on Sunday.那个老板让工人们周日休息。
5.作定语
动词不定式作定语时,应放在被修饰的名词或代词之后。如:
And she is believed to be the first to make it popular.她被认为是第一个让它流行起来的人。
6.作状语
(1)作目的状语。作目的状语既可放在句首,也可放在句末。如:
I have brought you a duck to celebrate the visit.我给你带了只鸭子来庆祝这次访问。
(2)作原因状语。如:
I’m sorry to hear that.听到那件事我很抱歉。
(3)作结果状语。常表示未预料到的、令人沮丧的结果。如:
A few years later we came to our home to find that our hometown had greatly changed.几年后我们回到家里,发现家乡发生了翻天覆地的变化。
7.动词不定式的特殊用法
(1)“疑问词+动词不定式”
①“疑问词+动词不定式”可以作主语、宾语或表语等。如:
Where to live is a problem.住在哪里是个问题。(作主语)
My question is how to find the answer quickly.我的问题是如何快速找到答案。(作表语)
②“疑问词+动词不定式”可与宾语从句进行相互转换。如:
I don’t know what to do next.=I don’t know what I should do next.我不知道下一步该怎么办。
The doctor told him when to take the medicine.=The doctor told him when he should take the medicine.医生告诉他该什么时候吃药。
(2)prefer to do sth.rather than do sth.宁愿做……而不愿做……
(3)“too…to…”“not…enough to…”结构
考点2动名词
动名词由“动词+-ing”构成,其否定形式为“not+动词+-ing”。其常见用法如下:
1.作主语
作主语时,谓语动词用单数形式。如:
Eating too much is bad for your health.吃得太多对你的健康有害。
2.作宾语
作宾语时,既可作动词的宾语,又可作介词的宾语,表示经常性的动作或长期的习惯。如:
He also liked taking his friends there.他还喜欢带朋友去那里。(2019.67)
You can send a sweet,simple message without saying a word.你可以不用说一句话就发出一个甜蜜、简单的信息。
3.作定语
作定语时,只表示它所修饰的词的用途、所属关系等,放在被修饰词之前。如:
She is in the reading room.她在阅览室里。
4.作表语
作表语时,构成系表结构,多数情况下可转化成主语。如:
His hobby is collecting stamps.=Collecting stamps is his hobby.他的爱好是集邮。
5.常见的后接动名词的词或短语
avoid避免 consider考虑 enjoy喜欢
finish完成 forget忘记 imagine想象
keep持续 like喜欢 mind介意
practice练习 remember记得 suggest建议
be busy doing sth.忙于做某事 be worth doing sth.值得做某事 be/become/get used to doing sth.习惯于做某事 can’t help doing sth.情不自禁做某事 feel like doing sth.想要做某事
