suggest sb to do还是doing

没有suggest sb to do的用法。suggest doing sth，意思是建议做某事。suggest sb doing sth，意思是建议某人做某事。suggest sth to sb，意思是向某人提出某情况。

suggest后面只能接doing

1.suggest sth 建议某事

He suggests a walk after supper.他建议饭后散散步。

2.suggest doing sth 建议做某事

I suggest wearing something warm.我建议穿暖和些。

3.suggest sth to sb/suggest to sb sth 向某人建议某事

My father suggested a friend to me.我父亲向我推荐了一位朋友。

4.suggest （that） sb (should) do sth 建议某人做某事

Tom suggested （that）she (should) go to see a doctor.汤姆建议她应该去看医生。

5.suggest one's doing sth 建议某人做某事

I suggest your opening the windows.我建议你打开窗户。

suggest用法

可以用后接that 从句的形式来表达向某人提出某情况(注意谓语用“should+动词原形”这样的虚拟语气形式)。如：I suggest that we(should) have lunch right now. 我建议我们现在就吃午饭。

suggest后接宾语从句时，从谓语既可用陈述语气，也可用虚拟语气，其区别与 suggest所表示的意思有关，若suggest表示“建议”，则其后接的that 从句谓语通常用“(should)+动词原形”这样的虚拟语气形式。若suggest表示“暗示”“意指”“表明”等义，则其后接的that 从句要用陈述语气。
