to do 和 doing作主语的区别

如题所述

  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)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。
  4)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.本回答被提问者采纳

本题题意为 为了保护动物,我们必须保护他们生存的地方
这里用 to do 作主语 表目的
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

它们的具体区别 语法书上都有的 希望我的回答可以帮到你

to do 表示不定式 后通常接动词原形 to do 做主语 有将来的含义
而doing是动名词 后接名词或者代词等
