不定式和动词ING做主语的区别：A:
1、动名词做主语往往表示普通的、一般的行为，不定式做主语常表示某次具体的行为。例如：
Collecting information about children’s health is his job. 收集有关儿童健康的信息是他的工作。
It’s necessary to discuss the problem with an experienced teacher. 与一位有经验的老师讨论这个问题是有必要的。
2、常用不定式做主语的句型有：
（1）It’s difficult (important, necessary) for sb. to do
（2）It’s kind (good, friendly, polite, careless, rude, cruel, clever, foolish, brave) of sb. to do.
3、常用动名词做主语的句型有：
It’s no good (use, fun) doing.
It’s (a) waste of time one’s doing.
ps：“collecting the information about childrens health”只是暂时行为，又不是一直都在收集。
开头的动词用作主语时可以用to do或doing，但要注意主一致原则，如：
To see is to believe.(两者都用to do）
Seeing is believing. (两者都用doing)
祈使句用动词原形开头，如：
Open the door.
Pass me the book.
hate [heit]
vt. 憎恨,恨;不愿,不喜欢
n. U憎恶,憎恨
参考例句
I hate to have my boss standing over me.
我不喜欢上司监督我.
He hates the smokiness of pubs and bars.
他讨厌酒馆和酒吧里弥漫的烟雾.
But it's a title Chou insists he hates.
但他本人并不喜欢这个称呼。
I hate standing on crowded train.
我讨厌站在拥挤的火车内。
I noted the hate and vehemence in his eyes.

I hate going to the theatre.
我讨厌去看戏。
I hate to come in the middle.
我不喜欢戏演到半中间时进场。
Bad treatment fanned their dislike into hate.
虐待将他们的不悦激成了恨。
总结下来,hate的用法有:
hate doing,hate to do,hate sth，hate sb doing
还有it形式宾语的用法如：
I hate it when people ask me for money.
