語法練習
1. (1999NMET) —Hey, Look where you are going!
—Oh, I’m terribly sorry. ________.
A. I’m not noticing B. I wasn't noticing
C. I haven't noticed D. I don't notice
分析：在沒有提供明確的時間，而是通過對話來體現(xiàn)情景，突出語言的交際功能。甲提醒乙“看看你往哪兒走啦!”乙說對不起“因為我剛才沒注意”，故應(yīng)用“過去進行時”，答案是B。
2. ( 1997NMET) —Who is Jerry Cooper?
—________? I saw you shaking hands with him at the meeting.
A. Don't you meet him yet B. Hadn't you met him yet
C. Didn't you meet him yet D. Haven't you met him yet
分析：從對話中可知甲還沒認出Jerry Cooper是誰，且yet常用于完成式的疑問句或否定句中表示“還沒有”或“也”等，故選D。
3.(2000NMET春)All the preparations for the task ________, and we're ready to start.
A. completed B. complete
C. had been completed D. have been completed
分析： all the preparations 與complete之間是被動結(jié)構(gòu)，故可排除A和B。又因下文are ready to start, 說明complete這一動作對“現(xiàn)在造成影響”，故用現(xiàn)在完成時。答案為D。
