专题三 非谓语动词
◆非谓语动词的考查要点
1．动词不定式复习中应注意的几个问题
(1)不定式作表语与“be＋to do sth.”的异同。不定式作表语说明主语的内容或性质。 My job is to teach English.(说明内容) be＋to do sth.(表示按计划要做的事) He is to go abroad.
(2)后接不定式作宾语的词语。
下列词语常接不定式作宾语：afford，promise，refuse，expect，hope，learn，offer，wish，want，fail，plan，agree，forget，like，prefer，decide，manage，try，arrange，determine，desire等。
下列词语后可接“疑问词＋不定式”：teach，decide，wonder，show，learn，forget，ask，find out，advise，discuss等。
(3)如何理解和使用不定式作宾补。
①动词(短语)see，watch，notice，hear，listen to，observe，feel，taste，smell，make，let，have等的宾补用动词原形，变被动时要加to，此时的不定式就是主语补足语。
②常用不定式作宾补的几种情况：
主语＋ask/require/tell/order/force/get/want/like＋sb.to do sth.
主语＋think/judge/suppose/believe/consider/imagine/feel＋sb.＋to be/to have done 主语＋call on/upon/depend on/wait for/ask for＋sb.＋to do sth. (4)不定式作定语的特殊用法。
①下列词语后常接不定式作定语：chance，wish，right，courage，need，promise，time，opportunity，way，the first，the second，the last，the only等。
②不定式作定语和所修饰的名词在逻辑上有主谓关系。 There is no one to look after her.
③不定式与被修饰的名词在逻辑上有动宾关系。 She is now looking for a room to live in. (5)不定式作状语的用法。
不定式作状语，在句中主要表示目的、结果、原因等。only to do表示出人意料的结果。 We hurried to the classroom only to find none there.
in order (not) to，so as (not) to用来引导目的状语；enough...to，so...as to do，such＋名词．..as to do作结果状语。
The girl was so kind as to help the old man off the bus.

I’m not such a fool as to believe that. (6)不定式的完成时的特殊用法。
①表示不定式中谓语动词发生的动作先于主句的谓语动词发生的动作。 The novel was said to have been published. I regret to have been with you for so many years.
seem，appear，be said，be supposed，be believed，be thought，be known，be reported等动词常用于上面句型。
此外，glad、happy、satisfied、sorry、surprised、disappointed后也接完成时，但要注意与一般时的区别。
I’m sorry to keep you waiting for a minute.对不起，请稍等。(说话时还未等) I’m sorry to have kept you waiting.对不起，让你久等了。(说话时已等了很久)
②不定式的完成时还可表示“过去本想做某事但未做”的虚拟语气。(A)should like to/would like to/would love to＋完成时。(B)was/were to＋不定式的完成时，表示该做某事或想做但未实现。(C)expect/hope/mean/promise/suppose/think/want/wish＋不定式的完成时，表示过去未曾实现的愿望。
(7)不定式的省略。
①同一结构并列由and或or连接。 I want to finish my homework and go home. I’m really puzzled what to think or say. 特例：To be or not to be，this is a question. It is better to laugh than to cry.(表示对比)
②不定式作表语，其前面的主语从句中含有do时，后面的to省略。 What he did was lose the game.
③句中含有动词do时，but，except，besides，such as等后面的to可省略。即“前有do，后省to”。
Don’t do anything silly，such as marry him.
④主句含有不定式，后面有rather than，rather than后省to。 ⑤Why not，had better，would rather，can’t but等词后省to。 You’d better take it seriously.
⑥多用在同一句或联系紧密的对话中，为了避免重复，作宾语、主补或宾补的不定式再次出现时，to后的内容常承前省略(只保留to即可)。但如果承前省略的不定式有助动词have或be的任何形式，后应该保留原形have或be。

—You came late last night. You ought to have finished your homework.

(1)下列动词后只能接动名词：suggest，finish，avoid，can’t help，mind，enjoy，require，practise，miss，escape，pardon，advise，consider，imagine，keep，appreciate，permit。
(2)下列动词短语后接动名词：leave off，put off，give up，look forward to，feel like，have trouble/difficulty (in)，devote to，be/get used to，pay attention to，be fond of，be worth。
(3)介词后要接动名词；what about，how about，be fond of，be good at等的介词后接动名词。注意on/upon doing sth.＝as soon as 引导的从句，作此意讲时on/upon后也可以接名词。

①begin，start，continue，like，love，dislike，hate，prefer，can’t stand 例句 1.It began to rain./It began raining. 2．It was beginning to snow. 3．I love lying (to lie)on my back. 4．I like listening to music，but today I don’t like to. 5．I don’t prefer to swim in the river now. 解析 1.意思无差别，但谓语动词用进行时时，后面只跟不定式。 2．表示一种倾向多接动名词作宾语，如果表示某一特定的或具体的行动，多接不定式。 http://www.xiexingcun.com/ http://www.eywedu.net/

The girls came in，following their parents. ④结果状语
The poor old man died，leaving nothing to his children.
注意：现在分词作状语的几个特性：①时间性。与谓语动词同时发生，用一般式，如发生在谓语动作之前时则用完成式having done。②语态性。与句子主语之间的关系，是主谓关系或动宾关系。遵循的规则“主动进行，被动完成”。③人称一致性。分词的逻辑主语就是句子的主语。
(2)现在分词作表语。
主语＋be＋v.-ed表示被动，主语是人；主语＋be＋v.-ing表示主动，主语是物。 4．过去分词复习中应注意的几个问题
过去分词作状语，可转换为相应的状语从句或并列分句，用来说明原因、时间、条件、伴随等。
(1)作原因状语
Tired by the trip，he soon fell asleep.
＝Because he was tired by the trip，he soon fell asleep. Lost in thought，he almost ran into a car.
＝As he was lost in thought，he almost ran into a car. (2)作时间状语
Seen from the hill，the city looks like a garden.
＝When the city is seen from the hill，it looks like a garden. (3)作条件状语
Given more time，I would have worked out the problem.
＝If I have been given more time，I would have worked out the problem. (4)作伴随状语
The teacher came in，followed by some students.
＝The teacher came in and (he) was followed by some students.
分词短语作状语时，通常与主句中的主语在逻辑上一致，但有时它也可以有自己独立的逻辑上的主语，这种结构称为独立主格结构。
