题目内容：

为什么是It is wrong of you to do that.不是It is wrong for you to do that. ?

优质解答

It is wrong of you to do that.对
It is wrong for you to do that.错
判断办法：
用of的情况：adj+of+人：当人+be（是）+adj合适时,就用of
又如：It is very kind of him to say so.(He is kind.合适)
用for的情况：adj+for+人：当人+be（是）+adj不合适时,就用for
It is necessary for me to learn English.(I am necessary不合适的）
