考点1.不定式和动名词作主语
动名词作主语多指抽象的、概念性的动作,可以是多次的、经常性的行为;不定式作主语多表示具体的动作,尤其是某一次的动作。
Smoking is forbidden in public places.(经常性的)
公共场所禁止吸烟。
It is impossible to go swimming this afternoon.(具体的)
今天下午去游泳是不可能的。
不定式短语作主语时,常用it作形式主语,而把不定式放在谓语之后。
It is right to give up smoking.戒烟是正确的。
“It is/was a waste of…/no use/no good/worth doing sth.”句型中常用动名词作主语。
It is worth making an appointment before you go.
你在去之前预约一下是值得的。
It was no use pretending that I had not seen him, so I waved to him.
假装没看见他已经没用了,因此我向他招了招手。

consider, suggest/advise, look forward to, excuse/pardon; admit, delay/put off, fancy

规则3 下列动词或词组既可以接动名词作宾语,也可以接不定式作宾语,但意义上有区别:
What a poor memory!I forgot borrowing money from him yesterday.But today I forget to return the money to him.
多么差的记忆力!我忘了昨天向他借过钱了,但今天我又忘了把钱还给他。

考点3.不定式和分词作定语
to do/to be done
作定语一般表示将来的动作
The professor to give us a lecture(=who will give us a lecture) tomorrow comes from Peking University.
明天要给我们做讲座的是一位来自北大的教授。
The problem to be discussed(=which will be discussed) at the meeting is very important.
会上将要讨论的问题非常重要。
done
表示已经完成的或被动的动作或者不强调时间性的被动动作
The problem discussed (=which was discussed) at the meeting is very important.
会上讨论过的问题非常重要。
a respected teacher (= who is respected)
一个被人尊敬的老师
doing
表示正在进行的或者经常性的主动动作或现在(或当时)的状态
The professor giving us a lecture(=who is giving us a lecture) now comes from Peking University.
正在给我们做讲座的是一位来自北大的教授。
being done
表示被动的、正在进行的动作
The problem being discussed(=which is being discussed) at the meeting is very important.
会上正在讨论的问题非常重要。
[小贴士] 使用to do/to be done作定语的情况:
(1)不定式用来修饰被序数词、最高级或no, all, any等限定的中心词,且与中心词为逻辑上的主动关系。
He is always the first to arrive at the school and the last to leave the school.
他总是第一个到校,最后一个离校。
(2)被修饰词是抽象名词时,常用不定式作定语。常见的该类名词有:ability, chance, idea, hope, wish, fact, excuse, promise, attempt, way等。
The ability to express an idea is as important as the idea itself. 表达观点的能力与观点本身同等重要。
(3)不定式与其修饰的名词之间在逻辑上有动宾关系。
I have a lot of work to do.
我有很多工作要做。
【小试牛刀三】
1.Behind the simple style, however, is a serious message (intend) for everyone.
2.She called for action (address) the struggles of people around the world (face) “too little water or too dirty water”.
3.Fearful that he might have an intention (harm) her, Helen started to run.
4.A visually-challenged man from Beijing recently hiked(徒步) 40 days to Xi’an, as a first step (journey) the Belt and Road route(路线) by foot.
5.Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure and offers a place where you can sit down to rest your (ache) legs.

【小试牛刀一】
1.listening 考查动名词作主语。空格处用动名词作主语,指多次的、经常性的行为,且为主动形式,故填listening。
2.Being 考查动名词作主语。空格处用动名词作主语,指抽象的、概念性的动作,故填Being。
3.to break 考查不定式作主语。根据句型“It takes sb/sth+一段时间+to do sth.”(花某人/物多长时间做某事。)可知,此处用动词不定式(to do)作真正的主语,it为形式主语。故填to break。
【小试牛刀二】
1.recording 考查动名词作宾语。spend time (in) doing sth意为“花时间做某事”。故填recording。
2.to continue 考查动词不定式作宾语。动词plan后面跟动词不定式,plan to do sth意为“计划做某事”,故填to continue。
3.to have 考查不定式作宾语。 aim to do sth意为“目的是……”,此处用不定式作宾语。故填to have。
4.to eat; trying 考查非谓语动词作宾语。mean to do sth意为“打算做某事”;can’t help doing sth意为“忍不住做某事”。故填to eat; trying。
5.being surrounded 考查动名词作宾语。avoid doing sth意为“避免做某事”,one和surround为被动关系,需用动名词的被动式。故填being surrounded。
【小试牛刀三】
1.intended 考查过去分词作定语。此处是过去分词短语作定语,修饰message。可改写为:which is intended for everyone。故填intended。
2.to address;facing 考查非谓语动词。分析句子结构可知,第一空在句中作目的状语,故用不定式。故第一空填to address; face与逻辑主语people构成主动关系,故用现在分词作后置定语,故第二空填facing。
3.to harm 考查动词不定式作定语。分析句子结构可知,空处应填非谓语动词,have an intention to do sth意为“有意向做某事”,用不定式作后置定语。故填to harm。
4.to journey 考查不定式作定语。此处journey为动词,表示“旅行”,step前面有序数词,用不定式作后置定语。故填to journey。
5.aching 考查现在分词作定语。名词legs与动词ache构成主动关系,故填aching。
