But they are afraid of you are not happy,

问题描述:

But they are afraid of you are not happy,

但是他们担心你不幸福

But they are afraid that you are not happy.

这是一句典型的中国学生学英语犯的错误,正确句子应该是
But they are afraid that you are not happy.
但他们担心你会不开心(高兴).
be afraid of后面不能接you are not happy这样的从句的,而一定接一个名词
I am afraid of snakes.
我怕蛇.
