Question

Which of the following is right? A.Could you tell me when he has been away?

B.There many students want to take part in the school sports meeting
c. I hope you to come here again.
D.We were told that sound travels through air.
请教哪个是正确的，错的错在哪里？

Answer 1

正确的应是D.
A.Could you tell me when he has been away?中when(指的是时间点)和完成时态不一起用，可改成Could you tell me when he left?或Could you tell me how long he has been away?
B.There many students want to take part in the school sports meeting.这是个中式英语句子，可改成There are many students who want to take part in the school sports meeting.或去掉there, 变成Many students want to take part in the school sports meeting
C.I hope you to come here again中hope没有hope sb. to do sth的用法。可改成I wish you to come here again或I hope you can come here again
D.正确。宾语从句用一般现在时表示客观事实，虽然主句用过去时。

Answer 2

A.Could you tell me when he has been away? when改成how long,
B.There many students want to take part in the school sports meeting ， there后要加are
c. I hope you to come here again. I hope you can come here again, 不可用to
D.We were told that sound travels through air.

Answer 3

A是对的
B应该是 there are many。。。。缺谓语
C应该是i hope you can come here again
D应该是we were told which sound...从句缺主语
