think后面加to do。think不能直接加doing,think后面加doing只有两种情况,1、think about doing考虑做某事;2、think of doing想起,想到要做某事。

think的用法是什么

一、think+宾语从句认为……例如：

1. I think you should phone Jenny and say sorry to her.

2. I think she should have paid the money back. 我认为她本应该偿还那笔钱的。

二、如果要否定think后面宾语从句的内容，常常用否定主句谓语动词的方式来表示，这种方式被称为否定转移，多用在第一人称的句子里。

例如： I don’t think he saw me. 我认为他没有看见我。

三、think sb / sth (to be) sth 及 sb / sth be thought to be sth / to do sth

例如： We all thought her (to be) very intelligent.

四、think+it+形容词/ 名词+(for sb)to do sth / that 从句， 表示“认为某人做某事怎么样“， it 是形式宾语，(for sb)to do sth 即不定式的复合结构或that 从句作真正的宾语，此时的that 不可省去。

五、 I think so. / I don’t think so. / I think not. 它们的意思是“我认为这样/我不这样认为/我认为不是”，可用来肯定或否定上下文提到的内容和对方所说的话。
