　　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。

Answer 3

不定式和动名词都可在句子中作主语，一般说来, 有下面几点须给予注意：
(1) 不定式一般表示具体的、特定的行为；而-ing分词一般表示抽象的、一般的行为。如：
To complete the program needs much effort. 完成这项计划需要很大的努力。
Riding a bike can make a man smart. 骑单车能使一个人敏捷。
(2) 在疑问句中，只能用动名词的复合结构作主语。如：
(3) 在某些句型中通常要用动名词短语作主语。如：It is no use doing…/ It is no good doing… / It is useless doing…/ It is worthwhile doing…如：
It is no use talking your trouble to a man like him. 跟他那样的人谈你的烦恼没有用。
(4) 一般说来，作主语和表语的非谓语动词形式应一致，即：或同时为不定式，或同时为-ing分词。如：
Seeing is believing. 眼见为实。
但是，在现代英语中，当表语用来说明主语的特定意义或具体内容时，主语和表语的非谓语动词的形式可以不一致，即，主语用动名词，而表语用动词不定式。如：
Waving your hand is to say “Good-bye”. 挥手就是说“再见”。
Nodding your head is to say “Yes”. 点头就是说“对，是的”。

Answer 4

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。

Answer 5

答：不定式to do sth. 和动名词doing sth. 都可以作主语。
不定式表示具体的、将要发生的事情，动名词表示抽象的、一般的事情。
如：To clear the blackboard is your job today.
Clearing the blackboard is an easy job.
有时两者意思差不多如：
To see is to believe.
Seeing is believing.
用形式主语it 而将真正的主语后置时，一般用不定式：
it is important to do sth.
It is good manners to do sth.
只有以下两个名词作表语时，用动名词：
it is no good/use doing sth.
