I don't know how to do it?
I don't know what to say?
I don't know at what time to start it?
I don't know which one should be chose?
I don't know at what time to go?
原答案第四句有错误,be + 过去分词 才能构成被动语态。即使改成“chosen”,被动语态结构也不如使用主动的结构好。
1、I have no idea what I should do.
2、I haven't found the way I say it.
3、I don't know the starting time.
4、I can't decide which one I should take.
5、I don't know the time to leave.
I don't know 都换成 i have no idea 就可以了
