【答案与解析】
1.
【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。
2. 【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”。
3.
【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。
4.
【解析】选A.we can’t get there by tomorrow 为客观事实，故宜用陈述语气。 5.
【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。
6.
【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。
7.
【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。
8. 【解析】8. 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.
9.
【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.
10.
【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。 【答案】C 11.
【解析】.根据上文的语境可知句中的 or 隐含有一个虚拟的条件，即 or=if I didn’t forget where I read the article（要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了）。
【答案】B 12.
【解析】关键信息是It looks as if he were drunk 中的虚拟语气，句子既然用了虚拟语气，也就是说，“他喝醉了”不是事实，只是他的言行好像是醉了，所以此题的最佳答案是D.
【答案】 D. 13.
【解析】 由于空格后的 if 条件状语从句的谓语用的是虚拟语气（这是很重要的信息），所以主句要用 would 而不用 will，即答案应选D.
【答案】D
14.
【解析】按照英语习惯，would rather 后接that 从句时，从句谓语通常要用虚拟语气，即用过去式表示现在或将来，用过去完成时表示过去。w.w.w.k.s.5.u.c.o.m
【答案】C 15.
【解析】insist后的从句谓语有时用“should+动词原形”这样的虚拟语气，有时不用，具体要看该谓语动词所表示的含义。一般说来，若该谓语动词所表示的动作尚未发生，或尚未成为事实，则用虚拟语气；若该谓语动词所表示的动作已经发生，或已经成为事实，则要用陈述语气。分析上题的句意，可知只有选D最合适。
【答案】D 16.
【解析】是因为时态前后有矛盾。由于主句谓语是would not have got，这表明是对过去事实作出的假设，所以从句谓语应该是 had given up，而不是像D项那样用一般过去时。另外，当虚拟条件句中有 had, should, were 等词时，通常可以省略 if，并将 had, should, were 提前置于句首。
【答案】B 17.
【解析】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。
【答案】B 18.
【解析】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。
【答案】B 19.
【解析】 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。
【答案】B 20.
【解析】without 引出的介词短语为一个与现在事实相反的含蓄条件句。 【答案】A 21.
【解析】句意：万一你被解雇，给你的医疗救助和其它方面的福利也不会被取消。 【答案】B 22.
【解析】句意：你想象不到这么一个表现良好的绅士竟然会对一个女士这么粗鲁。 【答案】C 23.
【解析】shall此处表示“警告”。 【答案】A 24.
【解析】B此处考查情态动词表示推测的用法。should have done表示过去应该做而
