15. -Have you moved into the new house?

-Not yet,　 the rooms ____.

14. -The window is dirty.

-I know. It_____ for weeks.

A. hasn’t cleaned　　　　　 B. didn’t clean

C. wasn’t cleaned　　　　　 D. hasn’t been cleaned

[解析]选D。it指上句中的window，是动作clean的承受者；同时时间状语for weeks加上语境中强调的是现在的情况，所以要用现在完成时。A项为主动语态；B项是主动语态，而且时态也不正确；C项是被动语态，但时态不合适。

13. -Do you like the material?

-Yes, it______ very soft.

A. is feeling　　　　　 B. felt

C. feels　　　　　　　　 D. is felt

[解析]选C。考查时态及语态。根据问句“Do you like the material? ”可知动作用现在时，且feel是系动词，不能用被动语态和进行时态，故选C。

12. The water will be further polluted unless some measures ____.

A. will be taken　　 B. are taken

C. were taken　　　　 D. had been taken

[解析]选B。主句为一般将来时，unless引导的条件状语从句通常用一般现在时表示将来，而“措施”应该是“被采取”，故用被动语态。

11. He will stop showing off, if no notice ____ of him.

A. is taken　　　 B. will be taken

C. takes　　　　　　 D. has taken

[解析]选A。在条件状语从句中通常用一般现在时代替将来时；根据句意，此处要用被动语态。
