suggest sb to do 还是suggest sb do还是suggest sb doing,为什么

Question

到底是to do还是doing啊?

Answer 1

suggest sb doing sth
suggest one's doing sth
suggest doing sth
suggest that......(should)

最后一个不是什么特殊形式，而是名词性从句中的虚拟语气，可以省略should，也可以保留。

Answer 2

suggest somebodt to do something 后面加的是宾语 省去的话是接着加动词原型

Answer 3

这是一个特殊的句型。

SUGGEST SB DO STH 可以理解为:

He suggested that we should speak more English.
这里的 SHOULD 是省略掉的。
