to do 是不定式 表目的 做主语时可以翻译为『为了什么什么』 doing是现代分词『又叫动名词』 做主语时和原型的意思没任何区别 只是以为主语必须是名词『动名词 物名词』和人称 所以要用动词做主语时 必须改变它的词性 也就是动词要变为动名词 这就是区别

to do和doing

作主语的区别

1

)一般来说,表示比较抽象的行为动作时多用动名词

doing

;表示比较具体的

某次行为动作时多用不定式

to do

。如:

No smoking is permitted here.

It is not very good for you to smoke so much.

Reading more is necessary.

It is quite necessary to read it again.

2

)在许多情况下,两者可以互换,意义上没有太大的差别。如:

Seeing him happy made me happy too.

It made me happy to see him happy.

It is useless learning something without practising it.

It is useless to learn something without practising it.

3

)不定式

to do

作主语时,常使用形式主语结构;而动名词

doing

作主语时,

较少用形式主语结构,只有在

It is no good, It is no use, It is useless, It is

worthwhile

等句型中出现

it

作形式主语现象。如:

It is hard to make him change him mind.

It is not an easy thing to master a language.

How would it be to start tomorrow?

It took all his strength to move out of the crowds.

It seemed a pity to give up the chance.

Business is business and it will not do to be so careless.

It is no good pretending to know what you don't know.

It is no use regretting the past.

It is worthwhile learning another language.

4

)在

there is no ...

句型中的主语只能用动名词

doing

,并且不能带逻辑主语。

如:

There is no denying the fact.

Well, you have said it and there is no taking it back.

上述句子的意思如用不定式

to do

则分别为:

It is impossible to deny the fact.

Well, you have said it and it is impossible for you to take it back.

5



doing

作主语时强调的是做那件事的状态,而

to do

作主语时主要表示一般

现在时或者是将来时的事情

Ⅰ.动名词和不定式做主语的相同点
1.不定式短语和动名词做主语时,常常为了保持句子的平衡,用it来做形式主语,如:
It is not easy to learn English well.
It is no use asking him for help.
2.如果主语用了不定式,表语和宾语也要用不定式;主语用了动名词,表语和宾语也要用动名词,这在英语中称为对称性,如:
To see is to believe. = Seeing is believing. (眼见为实)
(85)It is better to stay home than _A__ out.
A. to go B. going C. go D. gone
Ⅱ.动名词和不定式做主语的不同点
1.不定式做主语常表示具体的某一动作;表示泛指或一般的抽象的概念时,多用动名词,如:
(92)_B_ is a good form of exercise for both young and old.
A. The walk B. Walking C. To walk D. Walk
2.在”There/It +be+ no use(good/help/need)”之后常用动名词做主语,而少用不定式,如:
It /There is no use crying over the split milk.
It /There is no help taking this medicine.
但是如果该句型中用了for引出不定式的逻辑主语,就只能用不定式,如:
(93) There is no good for us to do that exercise.
3.不定式可以和when, where, how, what, whether等连用,在句子中做主语,宾语和表语,而动名词则不能,如:
How to solve the problem is a hot potato.
Where to put the box seems hard to decide.
Whether to do it hasn’t been decided.
What to do next is up to you.
连接上还有许多,可以借鉴。
