虚拟语气(超经典版)-北师大版高中英语必修五unit14careers

虚拟语气与真实语气相反，表示说话人的建议 、假设 、愿望。 一、一个句式：It is high/about time thatdid/ should do(should不可省略）(早）该做某事了，该结构往往用来表示早该做而未做的事情。 填空： It is high time that we (go) to bed. It is time that the children (have) lunch. It is about time that you (give) the little girl a hand. 注意：该结构不可混淆“It is time for sth”或者“It is time for sb to do sth”，意为“是某人做什么的时间了”。 It is time for class. 到上课的时候了。 It is time for her to answer the question. 是该她回答问题的时候了。二、两个词组：第一组以w开头的短语: 第二组都含有单词if 1. We wish we (have) large wings. 2. He wished he (not say) that. 3. I wish I (remember) his E-mail. 4. I would rather you (not tell) me the truth. 5. If only one (have) an unlimited supply of money! 6. If only I (have) another chance to study German. 7. He behaves as if he (have) no common sense. 8. The old lady treats the boy as if he (be) her own son.注意：would rather后如果接动词要加动词原形，关键要看后面有没有主语。 I would rather stay at home alone. I would rather die than live in disgrace.三、If虚拟条件句分三种时态：与现在事实相反、与过去事实相反、与将来事实相反。时态类型If引导的从句谓语动词主句谓语动词例句与现在事实相反1. 2. be would/could/should/might+ If I (be) you, I should study French.与过去事实相反1. would/could/should/might+ If you (take) my advice, you (not fail) in the test.与将来事实相反1. 2. 3. would/could/should/might+ If it (rain) tomorrow, the sports meeting (cancel). 特别注意：1. would/should/could/might 主句谓语中的should主要用于第一人称后；would表示结果还表示过去经常常常做某事，might表示可能性，could表示能力、允许或可能性。2错综时间虚拟条件句，即条件从句与主句所指时间不一致，如从句指过去，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整： If it had rained heavily last night, the ground would be wet now. You would be much better now if you had followed the doctors advice. 3. 与将来相反的虚拟条件句，是高考的一个出题方向，因为它不仅涉及到虚拟，还有倒装和强调涵盖其中（If虚拟条件句的倒装形式，即把if 省略，把were, had, should置于句首）。This printer is of good quality. If it _ break down within the first year, we would repair it at our expense. A. would B. should C. could D. mightThis printer is of good quality. _ itbreak down within the first year, we would repair it at our expense. A. Would B. Should C. Could D. Might如果改为下题呢?This printer is of good quality. _ it to break down within the first year, we would repair it at our expense. A. Would B. Should C. Could D. WereHad the boy worked harder, he the exams. A. must have got through B. could get through C. ought to get through D. would have got through四、四种动词：一坚持 二命令 三建议 四要求 含有这四种动词的的宾语从句中谓语动词用(should)+动词原形，should可省略 I suggest you (not buy) sony. They required that I (go) there tonight. The doctor strongly recommended that he (take) a holiday. 注意：suggest后面接动词时，要跟动名词形式: 只有在表示建议时而且后面加句子，才使用虚拟语气。当suggest做“暗示 、表明”讲时，就不使用虚拟了。 His words suggested that he (be) unhappy.当insist 作“坚持认为”时不用虚拟语气，当作“坚持要求”时，用虚拟语气。She insisted that I was wrong and that I should make a public apology to them.填空：He insisted that we (accept) these gifts.She insisted the he (be) wrong.5、 常见含蓄条件句 有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件句，而通过其他手段来代替条件句。 I was busy that day. Otherwise, I would have taken part in the sports meeting. (副词Otherwise 否则) He telephoned to inform me of your birthday, or I would have known nothing about it. (连词or 否则) Without/but for electricity human life would be quite difficult today.（介词）用所给动词的正确形式填空，注意使用合适的情态动词助动词1. If I _ him yesterday I _ him about it. (see, ask)2. What do you think would happen if there no light during the days? (be)3. But for your help, I couldnt _ the place. (find)4. If her lawyer here last Sunday, he her from going. (be, prevent)5. If it had not been for the liberation, no changes place in my hometown. (take)6. If Miss Green late tomorrow, who would take her place? (come)7. It seems as if it already summer now. (be) 8. I wish I him the day before yesterday. (see) 9. I made the suggestion that they the plan they had made. (stick)10. It is suggested that a study plan right now. (make)11.
