A.couldn’t B.shouldn’t C.can’t D.might not 解析 句意为：如果不是因为她不会唱歌的事实，我会邀请她来参加那次聚会的。that 从句为同位语从句， 描述的是事实，用陈述语气。正确答案为 C。 2. 与 过 去 事 实 相 反 的 虚 拟 语 气 ， 基 本 结 构 为 ： 主 语 + 动 词 的 过 去 完 成 时 + 其 他 成 分 +if+should/would/could...+have done+其他成分。例如： If the weather had been better，we could have had a picnic.But it ______ all day. A.rained B.rains C.has rained D.is raining 解析 句意为：如果天气好的话，我们是能够去野餐的，但是下了一天的雨。句子前半部分陈述的是与过去 事实相反的事情，所以用了虚拟语气。“下了一天的雨”是事实，所以用陈述语气。因为是发生在过去的事实， 所以正确答案为 A。 3.与将来事实相反的虚拟语气，基本结构为：主语+动词的一般过去时/should do/were to do+其他成分 +if+should/would/could...+动词原形+其他成分。例如： If I ______ plan to do anything I want to，I’d like to go to T ibet and travel through as much of it as possible. A.would B.could C.had to D.ought to 解析 句意为：如果我能够计划做我想做的事情，我想去西藏并且尽可能多玩一些地方。句子描述的是与将 来事实相反的事情，所以正确答案为 B。 考点二、含蓄虚拟条件句 这样的虚拟句不含有 if 从句，而是以 but for/without/or/otherwise 等引导的句子代替 if 从句，主句的 谓语动词的形式与前面虚拟语气的基本用法相同。例如： Thank you for all your hard work last week.I don’t think we ______ it without you. A.can manage B.could have managed C.could managed D.can have managed 解析 由语境可知这里要表达的意思是：如果没有你们辛勤的工作，我们不可能处理好这件事。很显然，这 是对过去发生的事实的虚拟，所以要用 could have done，故应选 B。 只有比别人更早、更勤奋地努力，才能尝到成功的滋味。 6 考点三、主从句时间不一致的虚拟条件句 在有些虚拟条件句中，主从句时间不一致，应根据不同情况区别对待。例如： It’s hard for me to imagine what I would be doing today if I ______ in love，at the age of seven， with the Melinda Cox Library in my hometown. A.wouldn’t have fallen B.had not fallen C.should fall D.were to fall 解析 句意为：如果不是我在七岁时爱上家乡的 Melinda Cox 图书馆的话，很难想象今天的我会是什么样子。 主句描述的是与现在事实相反的事情，从句描述的是与过去事实相反的事情。正确答案为 B。 考点四、名词性从句中的虚拟语气 在含有表示坚持、建议、命令、要求等含义的名词性从句和在 it 做形式宾语或形式主语的复合句中，宾语 补足语是 necessary/strange/essential/natural/a pity/a shame 等表示“惊奇、惋惜或者理应如此”等含义 时，从句中的谓语动词需用“should+动词原形”，其中 should 可以省略。例如： —Don’t you think it necessary that he ______ to Miami but to New York? —I agree，but the problem is ______ he has refused to. A.will not be sent;that B.not be sent;that C.should not be sent;what D.should not send;what 解析 问句句意为：难道你不认为必须把他送到迈阿密而不是纽约吗?句子表示理应如此的意思。正确答案 为 B。 情态动词考点透析 考点一、情态动词基本含义的考查 情态动词的基本含义，一直 是高考考查的重要内容。例如： 1. The fire spread through the hotel very quickly but everyone______get out. A. had to B. would C. was able to D. could 解析：考查情态动词的基本含义。had to：不得不; would：表示意愿或过去常常;could 倾向于表示经过长 期训练而获得的能力;was able to 表示经过努力而能够做到的事或成功地做了某事。因此，答案是 C。 分析：高考对情态动词基本含义的考查，仍然集中在常用的情态动词上。对常用情态动词的含义，要掌握 的既准确又要全面，特别是 shall, should, can, may 四个常用情态动词的含义较多，不易理解，复习时应当 引起重视。 二、情态动词表示推测的考查 对情态动词表示推测的用法，是高考考查情态动词的一个重要方面。例如： 1. Sorry, I’m late. I______have turned off the alarm clock and gone back to sleep again . A. might B. should C. can D. will 解析：might have done : (过去)可能做过某事;shouldhave done :本应该做某事。根据本句提供的情境 I’m late 表明说话人可能把闹钟关上了。答案是：A。 分析：高考对表示推测的情态动词集中在 must, can, could, may, might 上，准确掌握它们使用的场合， 是解决问题的关键。Must 用于肯定陈述句，表示肯定推测;can, could 用于疑问或否定陈述句，表示可能性推 测;may, might 用于陈述句，表示可能性推测;用于否定陈述句中，c an’t (不可能)的语气比 may not(可能不) 只有比别人更早、更勤奋地努力，才能尝到成功的滋味。 7 强。此外，还要注意有对过去和对现在两种情况的推测,对过去推测用情态动词+have done ，对现在推测用情态 动词+ 动词原形。 三、情态动词表示虚拟的考查 情态动词+have+过去分词表示与过去事实上相反的情况，也是高考单项选择题涉及到情态动词的一个重要 方面。 1. There was a lot of fun at yesterday’s party. You______come, but why didn’t you? A. must have B. should C. need have D. ought to have 解析：ought to have done 表示本来应该做某事而实际没做，should do 表示现在应该做某事，与题中 at yesterday’s party 表示的时间不一致。所以选 D。 分析：高考对情态动词表示虚拟‘用法，表示与过去事实相反的情况。近几年高考，主要侧重 should (not)have done 这一句式上，表示本来不该做却做了或本来该做却未做的事，在复习时，还应关注其它几种虚 拟形式，如 need (not)have done 表示本来需要做而未做或本来不需要而做的事等等，以做到有备无患。 考点四、情态动词与助动词混合考查 1.Tom ,you didn’t come to the party last night? —I______, but I suddenly remembered I had homework to do . A. had to B. didn’t C. was going to D. wouldn’t 解析：had to:不得不;didn’t:没来;was going to：打算来;wouldn’t:不愿来。句意：——汤姆，昨晚 你没来参加舞会吗?——我本打算来，但我突然记起有作业要做。But 是关键词，所以答案是：C。 2.Your phone number again? I______quite catch it . —It’s 86184867.

I’ve already borrowed one. A. can’t B. mustn’t C. needn’t D. shouldn’t 【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. 只有比别人更早、更勤奋地努力，才能尝到成功的滋味。 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.zxxk.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 l ives 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 只有比别人更早、更勤奋地努力，才能尝到成功的滋味。 12 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 表示过去应该做而实际并没有做，因此 淘汰 A 项。would 不用来表推测，因此淘汰 C 项。B 基与 D 项虽然都可以表示推测，但 B 项表肯定意义而 D 项表 示否定推测，意为“不可能”，根据句意：他肯定已完成了他的工作;不然，他就不会在海边玩得那么愉快了。 可知此处需要肯定意义，因此淘汰 D 项。 25. 【 解析】B 本题考查情态动词的用法。must 表示推测只能用于肯定句，否定句用 can 或 could 代替。 shouldn’t have done 表示“本来不该而实际上却做了某事”.needn’t have done 表示“本来不必而实际上 却做了”均不合题意。本句的意思是：当事故发生时我不可能超过 6 岁。 26. 【解析】C should(按道理)应该;句意：既然你在驾校时做了大量练习，那么通过这次考试理不应该有困难。 27. 【解析】B 第一句话使用了一般过去时，由此可知第二句话是对过去事情的猜测，需用 must have done. 本题意为“我正在高速公路上行驶，这时一辆警车跟随着着这辆车从旁边经过。它们一定是以至少每小时 150 公里的速度行驶。”故选 B。A 项表示“本应该……”，C 项表示“本能够……”不合题意。 28. 【解析】D 本题考查情态动词的用法。句意是“我错拿了别人的绿色 毛衣”，“那可能是 Harry 的，他总 是穿绿色的毛衣”。四个选项中 could 表示推测。mustn’t 表示 “禁止”;has to 表示“不得不”;will 表推 测时，表“肯定“语气太强。 29. 【解析】B 根据句意可知 Catherine 对对方为她打扫了房间表示感谢并提到对方本来不必为她打扫房间。很 显然对方打扫房间是过去所为，表达“去不必做某事”用 needn’t have done sth. 30. 【解析】C 本题考查情态动词，从答语的后半句“我已经借到一本字典了”，可知前半句为“不必了”。故 C 正确。
