complain to sb.向某人抱怨，complain about/of sth. 抱怨某事，complain to sb. about/of sth. 向某人抱怨某事，如He always complains to his parents about the weather.他總是向他父母抱怨天氣，complain that+句子。

complain about sth. 抱怨某事.如果要跟動詞的話,就要是現在分詞形式了,或者to do形式。complain about和complain of 的區別，意思上的區別，complain of 多了to say that you have a pain or are sick的意思。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。

用法上的區別，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?
