般过去时用法易错解析

请看下面的题目:

“Your phone number again? I _________ quite catch it.” “It’s 4331577”

A. didn’t B. couldn’t C. don’t D. can’t

【分析】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”。

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:

“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”应发生在过去。

“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。

“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。

“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。

“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。

“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。
