can't help to do还是can't help doing呢？

can't help to do还是can't help doing呢？

can't help to do和can't help doing的区别在于意思的不同，其他没有区别。

具体分析如下:

1、can't help to do意为不能帮助做某事。

如I am so sorry that I can't help to clean the room because of sickness.

我很抱歉因为生病不能帮忙一起打扫屋子。

2、can't help doing意为情不自禁做某事。

如I can't help shouting when he crossed the final firstly.

当他第一个冲过终点时我情不自禁叫了出来。

1、can't help to do和can't help doing都有时态的变化(过去式: couldn't help doing, 现在时: can't help doing)。

但是二者没有人称的变化(I / he / she / they / we / Phoebe can't help doing)。

2、can't help to do为动词不定式结构;can't help doing sth则是一个固定短语搭配。

3、can't还有一个搭配为can't but do表示别无选择只能...的意思。

eg.    I can't but let her go!

我别无选择只能让她离开。
