答案精解精析

Ⅰ.1.needn’t 句意:我爱周末,因为我不必在周六和周日早起。needn’t表示不必。

2.had told 句意:你上周为什么不告诉我你遇到的麻烦?如果你告诉我,我本可以帮你的。本题考查虚拟语气。根据题干中的could have helped和last week可知设空处为与过去事实相反的虚拟语气,故答案为had told。

3.hadn’t been 句意:如果不是因为那天他的邀请,我现在是不会在这里的。根据句意可知,本句为错综时间条件句。主句和现在的事实相反,从句和过去的事实相反,故从句谓语动词为过去完成时。 4.must 句意:——难道你不能再多待一会儿吗?——现在我真的必须得走了,我的女儿独自一人在家。本题考查情态动词。根据上下文可知,答案为must(必须)。

5.hadn’t seen 句意:如果不是我亲眼看到它,我是不会相信的。本题考查虚拟语气。由主句谓语“wouldn’t have believed”可知此处为与过去事实相反的假设,条件从句应该用过去完成时。 6.had known 句意:要是我知道安排的话,我可能会省一些事儿。本题考查虚拟语气。由主句 “It might have saved me some trouble”可知此处是与过去事实相反的假设,所以用过去完成时。

7.had been 句意:我希望上周二我参加了我姐姐的婚礼,可是那时我正在纽约出差。考查虚拟语气。wish后的从句对过去情况进行虚拟时谓语动词应用had done。

8.should 句意:我妈妈建议我们这个周末出去吃饭来换换口味。suggest作“建议”讲时,后面的从句要用虚拟语气,从句谓语动词用“(should+)动词原形”。

9.couldn’t 根据语境可知此处表示过去的能力,故用couldn’t。

10.Were 句意:要是没有现代化的电信系统,我们得等上几周才能获取世界各地的新闻。本题考查虚拟语气。根据主句谓语可知设空处表示与现在事实相反的假设,if条件从句谓语动词应为动词的过去式(be动词用were),即If there were...,在虚拟条件从句中可以省略if,把were提到句首。

11.have driven 句意:——你认为乔治通过驾照考试了吗?——没有。如果通过了,昨天他就会开车去我们大学了。由yesterday可知本句是与过去事实相反的假设,空格处为主句的谓语,故用have driven。 12.have been avoided 句意:得知如果他请了医生他儿子的死就可以避免,他总是感到很内疚。his son’s death与avoid为被动关系,故设空处需用被动语态;这里表示对过去的虚拟,空格前为情态动词,故需用“情态动词+have been+过去分词”,因此填have been avoided。

13.had 本题考查虚拟语气。根据句意可知从句是与过去事实相反的虚拟语气,其谓语应为 “had+过去分词”,本句中将if省略了,had提到句首,故设空处填had。

14.must 句意:——我确信今天上午我在公园里见到了Brian。——你一定是在胡思乱想,他昨天晚上离开去美国了。must表示肯定的推测,意为“一定”。
