问题补充:
Could you tell me ?
A. where do you live
B. who you are waiting for
C. who were you waiting for
D. where you live in
答案:
A. where do you live
(答案→)B. who you are waiting for
C. who were you waiting for
D. where you live in
解析:此题重点考查宾语从句的时态和语序问题,无论哪种句式结构充当宾语从句都要用陈述句语序,从句的时态要和主句的时态保持一致。where you live in这种表示是错误的,故选B。
