有关一般过去时的一个语境性考点

请看下面的题：

“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(from www.nmet168.com)。

(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(from www.nmet168.com)。

(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。
