Question

could you please tell me how longhe will be away

下列两句话哪里错了
1.Could you tell me me hou long you will be away?
2.I want to know whether he gives back the book.

Answer 1

正确的是：
1.Could you tell me how long you will be away?
2.I want to know whether he has given back the book.
第二句主句是一般现在式,宾语从句肯定得用现在式而不可能是过去时,从句子意思上看,应该是完成时,所以用一般现在完成时.
