complain about/of sth.對什么抱怨,關(guān)于什么抱怨
complain about和complain of 的區(qū)別：
1,意思上的區(qū)別,complain of 多了to say that you have a pain or are sick的意思,比如：She had
been complaining of headaches.
另外complain
of的抱怨是正式的,所以可以是法律上,向官方提出的.比如：Refugees had complained of being robbed and beaten
by officials.
2.用法上的區(qū)別
complain of / complain about 是接
sth或者動名詞
但是complain about 可以不帶,而complain of則不行.
比如：What are you
complaining about?
complain for 為了什么而抱怨 be complained by 被誰所抱怨,被動語態(tài)
