A. I’m not noticing                                   B. I wasn’t noticing

C. I haven’t noticed                                   D. I don’t notice

A. didn’t realize                                        B. haven’t realized

C. didn’t recognize                                    D. don’t recognized 

答案選C。“沒認(rèn)出是你”是說此話之前的事，說此話時顯然已經(jīng)認(rèn)出了對方。

(4) “What’s her new telephone number?” “Oh, I _____.”

A. forget                                                  B. forgot

C. had forgotten                                        D. am forgetting

此題應(yīng)選A，從語境上看，“忘記”的時間應(yīng)是現(xiàn)在，即指現(xiàn)在不記得了。

5. Mr Smith ______ a book about China last year but I don’t know whether he has finished it.

A. has written                                           B. wrote

C. had written                                           D. was writing

【陷阱】容易誤選B或C。

【分析】此題應(yīng)選D，這是由 but I don’t know whether he has finished it 這一句話的語境決定的，全句意為“史密斯先生去年在寫一本書，但我不知道他現(xiàn)在是否寫完了”。有的同學(xué)可能由于受 last year的影響而誤選B。但若選B，則句子前半部分的意思則變?yōu)?/FONT>“史密斯先生去年寫了一本書”，既然是“寫了”，那么這與下文的“但我不知道他現(xiàn)在是否寫完了”相矛盾。
