I am afraid we have to go now的afraid后面为什么不加to或of

Question

如题所述

Answer 1

I am afraid 后省略了of , (that) we have to go now 是介词of的宾语从句
这是一种固定用法。一些be +形容词 +介词的短语，常常省略介词再接that引导的宾语从句。如
be sure of/ about sth, be surprised at sth, be pleased with 等等
I'm sure (that) you are honest
I'm surprised （that) his father is an American
I'm pleased ( that) he finished the task in time.
如果这类短语后接特殊疑问词引导的宾语从句，则不省略介词
I'm pleased with what you said

Answer 2

be afraid of sth 害怕某物,某事
be afraid of doing sth 做了某事感到害怕
be afraid to do sth 由于害怕而不敢做某事
be afraid that 从句, 这句话是be afraid后面接的省略that的宾语从句

有不会的欢迎再继续问我(*^__^*)

Answer 3

I am afraid + 句子“ 恐怕”

起着缓和语气的作用。如果你有对方不太爱听的事要告诉对方的话，最好用这个结构。 如：

I am afraid I can't lend it to you.

你说的哪两种结构没有此功能

Answer 4

afraid后的是一个从句，可以理解为afraid后省略了连接词that
