是can to do sth.还是can do sth.

问题描述:

是can to do sth.还是can do sth.

can do sth

can 是情态动词
要接动词原形,所有的情态动词都要接动词原形
但是要到了具体的问题的时候要具体分析
举个例子:
He always does all things that he can to help me.
这个地方can后面仿佛是接的to
但实际上这里 that he can 是作定语从句修饰 things 的
to help 才是连在一起的,表示does all things 的目的

can do

can do sth
能做某事

看情况:1.I can answer your question.肯定是 can do something.
2.We do what we can to help him.用的是can to do,因为这个 can 后面省略了do,省略的原因是前面有实意动词do.

是can do sth.
can 加动词原形
