(2014湖南卷)If Mr. Dewey _ present, he would have offered any possible assistance to the people there.A. were B. had beenC. should be D. was1. 【答案】 C【解析】 句意：让我难过的是，他们自己那么穷，竟然还要给我带吃的。should此处意为“竟然”，表惊讶。2. 【答案】 A【解析】 句意：我可以和你谈谈吗？不会花很长时间的。表示询问对方是否允许，can与shall均可用于第一人称，但can侧重满足自身需求。根据句意可知，本题使用Can I.？更合适。3. 【答案】 D【解析】 句意：我已经为野餐准备了各种食物。你的意思是我们不必带任何东西了？本题考查的是情态动词否定意义辨析。cant(不可能；不能)；mustnt(禁止，千万不能)；neednt(不必；不需要)；shant(不应该)，常用口语形式。4. 【答案】 D【解析】 句意：生活是无法预测的，甚至最贫穷的人也许会成为最富有的人。shall(将要)；must(必须，一定)；need(需要)；might(也许)。根据前句“Life is unpredictable”，说明一切都有可能，所以使用might表示存在的可能性。5. 【答案】 D【解析】 句意：如果你没有把地图丢了，我们现在就会回到宾馆里了。本题考查的是if条件状语从句的虚拟语气。表示与现在事实相反时，条件句中使用一般过去时或were，主句使用would do形式。根据从句的did可知本句是与现在事实相反，故D项正确。6. 【答案】 A【解析】 句意：如果没有现代的电信业，要想得到世界各地的消息，我们就不得不等几个星期。本题题是一个if条件句的虚拟语气，表示与现在事实相反，if从句中使用过去时或were，主句使用would do形式；另外，在if从句中如含有were, had或should时，可在if被省略的同时，were，had或should放在从句句首构成部分倒装。7. 【答案】 D【解析】 句意：如果他赶上了早班火车，他就不会开会迟到了。本题考查的是if引导的条件状语从句的虚拟语气。表示与过去事实相反，条件句中使用过去完成时，主句使用“情态动词have done”；当条件句中的if省略的时候，要把had提前形成部分倒装，故D项正确。8. 【答案】 A【解析】 句意：在我们进行这项调查的这几个月里，他们在国外，要不然，他们就会来帮助我们的。本句考查的是一个含蓄的虚拟条件句，句中的or相当于if they had not gone abroad，因为前面句中使用的是were，说明这个虚拟语气是与过去事实相反，所以主句中使用的是“情态动词have done”的形式，故A项正确。9. 【答案】 D【解析】 句意：尽管你有时可能会在伦敦找到便宜货，但总的说来那不是一个购物便宜的地方。should(应该；竟然)；need(需要)；must(必须，一定；非得，偏偏)；can(能够，可能，有时会)。根据句意可知用can，表示“有时可能，有时会”。10. 【答案】 B【解析】 句意：如果Mr. Dewey在场，他就会向那里的人提供任何可能的帮助。本题考查的是条件状语从句虚拟语气中的与过去事实相反的情况。表示与过去事实相反的虚拟语气，条件状语从句要使用过去完成时，主句要使用“情态动词have done”。根据本句后面主句中的“would have offered”说明是与过去事实相反，故从句中使用过去完成时。高考中，试题对情态动词和虚拟语气的考核常常利用语境和句子之间意义上的细微差别来考查学生对该语法项目的理解与掌握。因此，在平时学习时准确理解和掌握情态动词的基本用法十分重要。情态动词和虚拟语气在高考中的热点依次为：对过去的虚拟语气，尤其是“情态动词have done”的考查频率较高；情态动词表推测和可能性；情态动词表示请求、允许和允诺；以及情态动词的否定。要点储备一：情态动词的基本用法情态动词用法否定式例句can能力(体力、智力、技能)允许或许可(口语中常用)可能性(表猜测，用于否定句或疑问句中)肯定句中表理论上的可能性，意为“有时会”How can it be that从句？ 怎么会？cant but do sth. cant help but do sth. have to do sth. 不得不做某事cant/can never. enough再也不为过cant help doing sth. / being done忍不住做can not / cannot /cant doA blind man cant judge colors.

They might have finished their task.3can和could意为“可能”，could表示可疑的可能性，不及can语气强，用于肯定句、否定句、疑问句中The weather in that city could be cold now. We could have walked there; it was so near.
