非谓语做表语

非谓语动词作表语

一：动词不定式在句中做表语：

1) To see is to believe. 2) To save time is to lengthen life.

3) To live is to work.

说明：不定式作表语,说明主语的内容，主语和表语位置可互换，不过泛指一般的习惯性动作最好用动名词，当表具体某一动作，最好用不定式。

Ex: 1) My task is ______the yard every day.(clean)

2) Her job is ______the yard today. (clean)

3) To be kind to the enemy is______ ( be) cruel to the people.

4) Their plan is_______ (build) another dormitory for their staff this year.

5) His wish is ______ (become) a pilot.

2)疑问词who, what, which, when, where, whether, how后可接不定式，构成不定式短语在句中作表语。

1) The question was where to get the medicine needed.

2) The question is how to put it into practice.

3）My question is where to find the answer.

4）The problem is____ ____ _____. 问题是去做什么。

5) The problem is____ ____ _____.问题是要买那一个。

6）The problem is____ ____ _____ . 问题是从哪里开始。

7）The difficulty is_________________________. 难题是如何尽快解决这个问题。

二：动名词在句中做表语，和主语的位置可以互换，句意不变。

My favorite thing is sleeping . = Sleeping is my favorite thing .

Their common hobby is collecting stamps.

= Collecting stamps is their common hobby.

Her job is washing, cleaning and taking care of the children.

= Washing, cleaning and taking care of the children is her job.

What I hate most is being laughed at.

= Being laughed at is what I hate most

1) 动名词和不定式作表语常可互换，不过泛指一般的习惯性动作最好用动名词，当表具体某一动作，最好用不定式。

Ex. 1) His part-time job is ______ (promote) new products for the company.

2) Reading is for sure________ (learn), but applying is also______(learn) to a

greater extent . 读书当然是学习，然而运用在更大程度上更是学习。

3) What he likes is _____ films. (see)

What he likes this afternoon is _____ this film.(see)

2) 动名词的复合结构作表语:

What matters most is his______ ( act).

What surprised us most is his ______ (speak).

二）现在分词作表语，通常具有形容词性质，主语通常是物；且不能和主语的位置互换。EG：The news was disappointing . The story is interesting.

His speech is an inspiring.What he said was very encouraging．EX: 1) Her letter was________（touch).她的信很感人。

2) The situation (形式) was ________ (surprise).

3) Traveling is interesting but______ ( tire).

4) The argument is very_________ ( convince). 他的论点很令人信服。

5) He remained _______ (stand) beside the table.他依然站在桌旁。

6) The music sounds______ ( relax) .

三) 过去分词作表语, 通常具有形容词性质,且主语通常是人。

EG：1) The cup is broken. 2) I'm interested in it.

3) The children were satisfied with his explanation.

EX: 1) The pupils will get______( confuse) if they are made to learn too much.

如果让学生学得太多，他们会感到糊涂的。

2) They were very _______ (excite) at the news.

7) The long lecture was ______ (bore) so we all were ______ (bore) with it .

8) We will feel _______ (relax) if music sounds ________ (relax).

9) The prefessor are pretty _______when the experiment is really ______ (satisfy). 四）现在分词作表语时，相当于形容词（即现在分词形容词化），与谓语动词进行时形式一样，两者容易混淆。但可以从意义上予以区别。

试比较: 1.The film is moving. 这电影很感人。(表语，说明主语的性质)

2.They are moving next Sunday . 他们下个周日搬家。(现在进行时，表示动作)

五）过去分词作表语时，相当于形容词（即过去分词形容词化），与谓语动词被动语态形式一样，两者容易混淆。但含义截然不同，过去分词作表语，主要是表示主语的状态，而被动语态则表示动作是被动发生。

试比较: 1. The cup was broken。

The cup was broken by my little sister yesterday.

茶杯是昨天我小妹打碎的。(是被动语态，表示动作)

2. The bookstore is now closed. 书店现在已关门了。(表语，说明主语所处的状态)

The bookstore is usually closed at 7:30 p. m. 书店通常7:30关门。(被动语态，表示动作) 3. We were moved.

We were moved by his words again and again .
