she is married to a man whom i thought was a lunatic

时态问题啊
改为:she was married to a man whom i thought was a lunatic
她与一个我认为是白痴的人结婚了

我觉得这里应该用that，这算是两个句子的合并了，前面是她嫁给了一个人。这里的“一个人”是宾语，但是后面这句我觉得这个人是个白痴里，“这个人”又成了主语。还有就是时态问题，前面用IS，后面用THOUGHT，要么都换成现在时，要么都换成过去时
She was married to a man, and I thought he was a dork.

Lunatic就是疯子，骂人的话.
