21. –Bruce, I really appreciate your handwriting.
- .
A. I practice every day B. Thank you very much
C. No, I don’t think so D. Well, it’s not good enough
【答案】B
【解析】考查交际用语。前一句表示赞扬，应答句应表示感谢，故选B。
22. -Why does the Lake smell terrible?
-Because large quantities of water .
A. have polluted B. is being polluted C. has been polluted D. have been polluted
【答案】D
【解析】考查动词时态，语态和主谓语一致。根据前一分句可知所填动词表示过去发生的动作对现在产生的影响，时态用现在完成时，动词与主语是被动关系，用被动语态。主语是large quantities of water，其中心词是quantities，是复数，谓语动词用复数，选D。
