问题：complainof和complainabout有什么区别？ 
回答：1，意思上的区别，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.用法上的区别

complain of / complain about 是接 sth或者动名词
但是complain about 可以不带，而complain of则不行。

比如： What are you complaining about?
