1. 动名词与动词不定式

动名词的形式：动词后面加ing，如：doing, seeing

有些动词后面如果有动词跟随时，必须跟动名词形式，如：

I enjoy playing football.

I don't mind waiting.

只能跟动名词的还有finish

动词不定式的形式：动词前面加to，如：to do , to see

当一些动词后接动词时，必须接不定式，如:

I want to play football.

I hope to go to England.

只能跟不定式的还有help, choose, offer

有些动词后面可以跟不定式或动名词，意思相同，比如:

I like swimming.

I like to swim.

I begin writing a letter.

I begin to write a letter.

类似用法的还有hate, love, continue

有些动词后面可以跟不定式或动名词，但意思不同，比如:

I stop writing the letter.(我停止写信——停下现在做的事)

I stop to write a letter.(我停下来，去写信——停下现在做的事，去干......)

I remember having my key with me.(我记得带钥匙了——过去做的事)

Please remember to have your key with you.(请记住带钥匙——将要做的事)

类似用法的还有forget

形容词后面通常跟不定式，如：

It is difficult to move the furniture.

I am so happy to see you here.

介词后面通常跟动名词，如：

I am good at speaking English.

He is not interested in seeing a movie.

2. 将来时中will的使用

谈论我们认为将要发生的事情

Tom will be late for school.

意愿

I will eat a lot of candies.

I won't tell him.

will后面要跟动词原型

常与I think, I believe, I hope, maybe, probably在一起表示猜测

I think she will pass the exam.

Maybe it will snow tomorrow.

与probably在一起时的使用方式：

He will probably come tomorrow.

He probably won't come tomorrow.
