虚拟语气专项练习

Answer 1

1. If my lawyer had been here last Saturday, would have prevented me from going.

解析：A. 本题考查虚拟语气。因为从句表示与过去事实相反的假设，故从句谓语动词用过去完成时，而主句谓语动词用would have +过去分词形式。

2. If I had worn my overcoat, I couldn’t have caught cold.

解析：B. 本题考查虚拟条件句中主句谓语动词的使用。因为从句用了过去完成时，可知主句谓语动词用would / could have +过去分词形式。根据句意，可知选B.

3. —If he was warned, he would not take that food. —Luckily he was sent to the hospital immediately.

解析：B. 根据答语，可知本题考查与过去事实相反的虚拟语气。故从句谓语动词用过去完成时，而主句谓语动词用would have +过去分词形式。

4. I didn’t see your sister at the meeting. If she had come, she would have met my brother.

解析：D． 根据句意“在会上我没有看到你的姐姐。如果她来的话，她就见到我哥哥了”可知，这是考查对过去事实的虚拟。主句用could have done，故从句谓语动词应该用过去完成时。

5. “I still haven’t thanked Aunt Lucy for her present.” “It’s time you did.”

解析：选B。It’s time you did 为 It’s time you thanked Aunt Lucy for her present 之略。按照英语语法，it’s time 后从句通常要用过去式。

6. If I hadn’t been lucky enough to meet you, I wouldn’t know what I would have done.

解析：选A。虽然前有虚拟条件句, 后有使用了虚拟语气的宾语，但 I don’t know 却宜用一般现在时，因为 I don’t know 表述的是现在的真实情况，句意为“我要不是有幸遇到你，我真不知(指现在不知)我会做出什么蠢事来”。

7. “I’ve told everyone about it.” “Oh, I’d rather you hadn’t.”

解析：选B。I’d rather 后接从句时，从句谓语的时态规律是：用过去式表示现在或将来，用过去完成式表示过去。

8. It has been raining for a day, but even though it hadn’t rained, we can’t get there by tomorrow.

解析：选A。we can’t get there by tomorrow 为客观事实，故宜用陈述语气。

9. “Do you know his address?” “No, I also wish I knew where he lives.”

解析：选B。第一空填 knew，因为 I wish 后的宾语从句要用虚拟语气(即用过去式表示现在的想法);第二空要填lives，即用陈述语气，因为 where he lives 是一个客观事实，而不是 I wish 的内容。

10. “Isn’t it about time you began to do morning exercises?” “Yes, it is. Would you like to join us?”

解析：选C。It’s time… / It’s high time… / It’s about time… 等后接从句时，从句谓语通常用过去式。

11. It is hard for me to imagine what I would be doing today if I had not fallen in love, at the age of seven, with the Melinda Cox Library in my hometown.

解析：选 B。此题涉及错综时间虚拟条件句，主句与现在事实相反，条件句与过去事实相反。句意为：要不是在七岁时就迷上了 Melinda Cox 图书馆，我真不能想像我如今会在做什么。

12. He hesitated for a moment before kicking the ball, otherwise he would have scored a goal.

解析：选 D。这是otherwise 引出的含蓄虚拟语气，再根据前面的 hesitated 可进一步知道这是与过去事实相反的虚拟语气，由此可推知答案选 D。

13. If only he had lain quietly as the doctor instructed, he would not suffer so much now.

解析：选 C。if only 意为“要是……就好了”，其后的句子谓语要用虚拟语气，同时根据 as the doctor instructed 中的过去时态可知从句是与过去事实相反，故选 C。

14. Without the air to hold some of the sun’s heat, the earth at night would be freezing cold for us to live.

解析：选 A。without 引出的介词短语为一个与现在事实相反的含蓄条件句。

15. Yesterday, Jane walked away from the discussion. Otherwise, she might have said something she would regret later.

解析：选 D。otherwise 在此相当于 if she had not walked away from the discussion，即暗示一个与过去事实相反的虚拟条件句。
