非谓语动词做表语 (2)

非谓语动词做表语
做表语用的非谓语动词有：不定式(todo),动名词(doing),和分词(done, doing)
■不定式做表语
1.Her wish was to become an artist.她的愿望是成为一位艺术家。

2.The most important thing is to put the ory into practice.最重要的是要把理论应用到实践。

3.Our aim is to help them, not to teach them a lesson.我们的目的是帮助他们，而不是教训他们。

总结：不定式做表语表示主语的具体内容，如例1；表示将来的动作，如例2；表示目的，如例3。

因此，在表示''目的，愿望，梦想，需求''等名词做主语时其表语应该用不定式. 4._________________ What he did was (wait)答案：wait 或是to wait
分析：当主语局部含do这个实义词，表语所说的是do的具体内容，这时表语局部的动词用todo或do的形式。

例如：All that he could do was(to) comfort her.他所能做的一切就是抚慰她。

■动名词做表语
l.My job is teaching.(Teaching is my job.)
2.Seeing is believing.百闻不如一见。

总结：动名词做表语，表示抽象概念。

动名词做表语一般用来表示''身份，职业〃等.大局部时候主语与表语可以互换，如例1。

此外，还要注意主语与表语的一致性，如例2。

例2还可以说成：To see is to believe.
［比拟］一般来说，表示比拟抽象的一般行为时多用动名词做表语;表示具体某次动作，特别是将来的动作时，多用不定式.
例如：Their job is building houses.他们的工作是盖房子.
Our task now is to develop our economy.我们的任务是开展经济.
有时两者都可以用，没有什么差异.
例如：What she likes is watching the children play.(=What she likes is to watch the children play.)她喜欢的是看孩子们玩.
■分词做表语
首先做一些练习
1.The situation is___ (encourage).
2.The door remained___ (lock)when he came again.
答案：
总结：surprise, interest, excite, puzzle, disappoint, astonish, encourage, inspire, shock, move等及物动词用做表语时，要看其与主语的关系。

如果与主语为主动关系，那么用・ing形式，表示主语的特征。

如果是被动关系，用-done这种形式，表示主语的状态。

如：The news astonished us.这句话就说明了the news与astonish为主动关系。

astonish与us为被动关系。

那么就可以直接得出以下两个句子：
1)The news was astonishing.
2)We were astonished(by the news).
练习：
3.She looked ____ (disappoint).
4.The news is quite __ (astonish).
答案:
有时候动词的过去分词作用在be动词之后，并非是被动语态，而是做表语表示事物存在的状态。

如：
5.The bottles are broken.杯子都破了。
