sb to do sth 造句

The teacher told her students to open their books.

sb to do sth 用法本身就错误

你这都没系动词/BE动词

是sb be to do sth 吧

E.G: Joy is to go shopping乔咿打算去购物
I'm to play basketball我打算去打篮球

ask sb. to do sth. : I ask him to take it to the room.
sb. decide to do sth. : I deside to study hard.
sb. want to do sth. : She want to watch TV.
楼上是错的，应该是Joy is going to go shopping.
I'm going to play basketball.

He asked me to do the housework.

I want you to do your homework

I want to clean the house
