YOU had trouble finding this place,后面为什么用DIDN’T YOU提问?

问题描述:

YOU had trouble finding this place,后面为什么用DIDN’T YOU提问?
HAD是什么成分?
we have saved very little后怎么有HAVEN’T WE提问?句中HAVE 是什么成分

you had trouble 这个had是实意动词,有的意思 所以反义疑问句得用助动词did 即didn't we.
下面这句,save是动词.have 是助动词,现在完成时的结构have + 动词过去分词 反义用haven't +主语
