ask后面加todo还是do

ask后面应该是加to do，而不是只加do，ask somebody to do something，这是一个固定搭配，意思是要求某人去做某事。ask后可带直接宾语和间接宾语，如ask his name和ask him。也可带双宾语，但是要注意将间接宾语（指人的词）先放在前面，中间不需要任何介词连接。

ask和ask for的区别

二者都有“请求”之意。其区别是：

1、搭配范围不同：ask后接抽象名词作宾语。例如：

She asked a favour of me.她请求我帮忙。

而ask for的宾语既可是抽象的，也可是具体的东西。例如：

The beggar asked him for bread.

那个要饭的向他要面包吃。

He asked me for my address.

他向我要地址。

2、使用句型不同：如果要说出被请求的人，前者可用ask sb sth或ask sth of sb；而后者则用asked for sb's sth或asked sb for sth。
