2. Although he has lived with us for years, he ___ us much impression. (2004年上海春季卷)

A. hadn’t left

B. didn’t leave

C. doesn’t leave

D. hasn’t left

2)考查一般现在时的替代用法：在以when, till/ until, as soon as, by the time, after, before 等引导的时间状语从句，在以if, unless, once等引导的条件状语从句和以no matter, however, even if 等词引导的让步状语从句中，如果主句中的动词用一般将来时，从句中的动词通常用一般现在时代替一般将来时。如：

3. — What would you do if it _____ tomorrow?

— We have to carry it on ,since we’ve got everything ready. (2005年全国卷)

A. rain B. rains

C. will rain D. is raining

二、对一般过去时的考查

一般过去时表示在过去某时某刻发生的动作或存在的状态，它常与表过去的时间状语连用，如yesterday, last year, last night, the other day, just now, then, two days ago, in 1999, at that time等。但是一般过去时也经常用在没有说明过去的时间状语的句子中，这是高考的命题方向。如：

4. More than a dozen students in that school ____ abroad to study medicine last year. (2005年上海卷)

A. sent

B. were sent

C. had sent

D. had been sent

三、对现在进行时的考查

现在进行时由“be+现在分词”，被动结构为“amisare+being+过去分词”构成。如：

5. — What’s the terrible noise?

— The neighbours ____ for a party. (2004年北京卷)

A. have prepared

B. are preparing

C. prepare

D. will prepare

注①表示感觉、愿望和状态的某些动词have, hear, see, like, contain, belong to, have on, understand, know 等一般不用进行时。

②进行时与always, often, forever, constantly等连用，表示一种感情(如赞扬、厌烦等)。

③现在进行时与一般现在时的区别是：前者表示动作的暂时性而后者表示动作的长期性。

四、对过去进行时的考查

1)把过去进行时放在when, while, as 等引导的时间状语从句中考查。如果主句谓语和从句谓语都发生在过去，动作时间长的用过去进行时，表达谈话背景;动作时间短的用一般过去时，表达新的信息。

A. was waiting

B. had waited

C. am waiting

2)把过去进行时放在某特定的语境中考查。
