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’tC. 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. promisesB. promisedC. will promiseD. 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 noticingB. I wasn’t noticingC. I haven’t noticedD. 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 realizeB. haven’t realizedC. didn’t recognizeD. 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. forgotC. had forgottenD. 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 realizeB. didn’t realizeC. hadn’t realizedD. 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 realizeB. haven’t realizedC. didn’t realizeD. hadn’t realized答案选C。“没意识到”是在听到的话之前的事。
