如题所述
应该是动名词而不是现在分词做主语,而动名词做主语和不定式做主语区别主要有以下几点:
1.不定式作主语经常表具体的动作,常与特定的连用(具体),而动名词作主语经常表示抽象的动作,一般不与特定的执行者连用(抽象)。
2.It's no good/use/fun+doing sth.
It's no use talking to him again.
It's no good eating too much fat. 这里it是形式主语,而真正的主语是动名词,但如果加了执行者,应该用:It's no good for you to eat too much fat.
3.It is dangerous climbing a tree.
It is terrible not being allowed to smoke at all.
It is nice helping other people.
It is interesting planning a holiday.
但important,necessary,possible,impossible...等形容词不能用上述结构,如 It's important learning foreign languages.(×)
It's important to learn foreign languages.(√)
4.主语与表语必须一致。
Eg. To see is to belive.(√)
Seeing is believing.(√)
