begin doing和begin to do的区别

begin doing和begin to do的区别

1）begin后跟to do或doing，含义上没有多少差异。如果谈论一个长期的习惯动作开始养成时，更加常用begin doing。例如：

How old were you when you first began playing the piano?

2）当begin后接表示心理活动的词时，比如：understand，realize，believe，wonder，

know，think等动词时，用begin to do。例如：She began to think she was wrong after a second thought.

经过重新考虑后，她开始认为她错了。

3）当begin用于进行时态时，其后跟to do。如：Mary is beginning to do her homework.

4）当主语是物或用于描述天气变化时，其后跟to do。如：

The water began to boil. 水开始开了。

It began to get dark before we knew it. 不知不觉地天黑下来了。
