◆典型陷阱题分析◆

    1. "I _____ his telephone number." "I have his number, but I ____ to bring my phone book."

    A. forget, forget                                        B. forgot, forgot

    C. forget, forgot                                        D. forgot, forget

    【陷阱】容易误选A，认为"忘记"是现在的事。

    【分析】仔细体会一下对话的语境：第一个人说"我忘记他的电话号码了"，这个"忘记"应该是现在的情况，即现在忘记了，要不然就没有必要同对方说此话了，故第一空应填 forget；第二个人说"我有他的号码，但我忘记带电话本了"，这个"忘记"应该是过去的情况，即过去忘记带电话本，所以现在电话本不在身上（注意句中的转折连词 but），故第二空应填 forgot，即答案选应C.请再看一例：

    - Oh, I ______ where he lives.

    - Don't you carry your address book？

    No, I ______ to bring it.

    A. forget, forget          B. forgot, forgot

    C. forget, forgot          D. forgot, forget

    答案选C，理由同上。

    2. I had hoped to see her off at the station, but I _____ too busy.

    A. was                  B. had been

    C. would be             D. would have been

    【陷阱】容易误选B或D，认为前句用了had hoped，所以此句谓语要用B或D与之呼应。

    【分析】但正确答案为A，前一句谓语用had hoped，表示的是过去未曾实现的想法或打算，可以译为"本想"，而后一句说"我太忙"，这是陈述过去的一个事实，所以要用一般过去时。请做以下类似试题（答案均为A）：

    （1） We had hoped to catch the 10：20 train, but _____ it was gone.

    A. found               B. had found

    C. would find          D. would have found

    （2） We had hoped that you would be able to visit us, but you _____.

    A. didn't                    B. hadn't

    C. needn't                   D. would not have

    （3） We had wanted to come to see him, but we ____ no time.

    A. had                    B. had had

    C. would have             D. would have had

    （4） I had expected to come over to see you last night, but someone ______ and I couldn't get away.

    A. called  B. had called

    C. would call D. would have called

    （5） The traffic accident wouldn't have happened yesterday, but the driver _______ really careless.

    A. was B. is

    C. were D. had been 

3. Dear me！ Just _____ at the time！ I _____ no idea it was so late.

    A. look, have  B. looking, had

    C. look, had D. looking, have

    【陷阱】此题容易误选D，认为第一空用现在分词表伴随，第二空填 have 的一般现在时，以保持与前面时态的一致性。

    【分析】其实，此题应选C，第一空应填 look, 因为这是祈使句的谓语；第二空应填 had，因为前一句说"看看时间吧"，这一看当然知道了现在很迟的情形，"不知道这么迟了"显然应是"过去"的事，故应用一般过去时态，许多同学由于忽略这一隐含的语境而误选。

    4. "Your phone number again？ I _____ quite catch it." "It's 4331577"

    A. didn't B. couldn't

    C. don't             D. can't

    【陷阱】此题容易误选C，认为此处要用一般现在时态，表示现在"没听清对方的话"。

    【分析】其实，此题答案应选A，根据上文的语境"请把你的电话号码再说一遍好吗？"可知"没听清对方的电话号码"应是在说此话以前，故应用一般过去时态。请看以下类似试题：

    （1） "Mr Smith isn't coming tonight." " But he _____."

    A. promises B. promised

    C. will promise D. had promised

    答案选B，"他答应（要来）"应发生在过去。

    （2） "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

    答案选B，"我没注意"是对方提醒之前的事，现经对方一提醒，当然注意到了。

    （3） "Oh it's you！ I ________ you." "I've had my hair cut."

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

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

    答案选C."没认出是你"是说此话之前的事，说此话时显然已经认出了对方。

    （4） "What's her new telephone number？" "Oh, I _____."

    A. forget                            B. forgot

    C. had forgotten                     D. am forgetting

    此题应选A，从语境上看，"忘记"的时间应是现在，即指现在不记得了。

    （5） "Since you've agreed to go, why aren't you getting ready？" "But I ______ that you would have me start at once."

    A. don't realize                    B. didn't realize

    C. hadn't realized                  D. haven't realized

    答案选B."没意识到"是对方提醒之前的事。

    （6） "It's twelve o'clock, I think I must be off now." "Oh, really？ I ______ it at all."

    A. don't realize                 B. haven't realized

    C. didn't realize                D. hadn't realized

    答案选C."没意识到"是在听到的话之前的事。 

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】容易误选B或C.

    【分析】此题应选D，这是由 but I don't know whether he has finished it 这一句话的语境决定的，全句意为"史密斯先生去年在写一本书，但我不知道他现在是否写完了"。有的同学可能由于受 last year的影响而误选B.但若选B，则句子前半部分的意思则变为"史密斯先生去年写了一本书"，既然是"写了"，那么这与下文的"但我不知道他现在是否写完了"相矛盾。

    6. He has changed a lot. He _______ not what he _______.

    A. is, is                        B. was, was

    C. is, was                       D. was, is

    【陷阱】几个干扰项均有可能误选。

    【分析】最佳答案选C，上文说"他"变化很大，即"他"现在不是过去的那个样子了，故第一空填is，第二空填 was（其实第二空也可用 used to be）。请看类例：

    "What place is it？" "Haven't you found out we _____ back where we ______？"

    A. were, had been                  B. have been, are

    C. are, wereD. are, had been

    答案选C，We are back where we were 的意思是"我们（现在）又回到刚才来过的地方"。

    7. He is very busy. I don't know if he _____ or not tomorrow.

    A. come                          B. comes

    C. will comeD. is coming

    【陷阱】此题容易误选B.认为 if 引导的是条件状语从句，从句谓语要用一般现在时表示将来意义。

    【分析】其实，此题答案应选C，句中if引导的不是条件状语从句（即if≠如果），而是宾语从句（即if＝是否），句意为"他很忙，我不知道明天他是否会来。"请看以下类似试题：

    （1） I don't know if she _____, but if she ____ I will let you know.

    A. comes, comes        B. will come, w
