Period 8Grammar用所给词的适当形式填空1Without electricity，life _ (be) quite different today.2Mr.Green demanded that Rose _ (leave) class before nine.3I dont know the word.If I _ (know) the meaning of it，I wouldnt have to look it up.4He made the suggestion that we _ (go) by train. 5He hesitated for a moment before kicking the ball；otherwise，he _ (score) a goal.6You _ (not make) such a serious mistake if you had followed my advice.7If I had studied hard，I _ (win) the scholarship now.8If I _ (not catch) by something，I would have come to your party yesterday.9The picture exhibition bored me to death；I wish I _ (go) there.10If I should see him tomorrow，I _ (invite) him home.一、will和be going to 用法比较1两者都可以表示预测将要发生的事。be going to强调从目前的证据或迹象表明可能发生某事；而will则表示依据直觉、知识、经验等做出的揣测。I told you to come early.Youre going to have trouble.我告诉过你要早来。你要有麻烦了。There will be a day when all computers in the world break down.将来有一天世界上所有的计算机会全部出故障。2两者都用来表示意图。但be going to do sth.强调“打算”和“意向”；而will强调“意愿、愿望”和“意志”。I am not going to argue with you tonight.今晚我不想同你争辩。He was going to take her to a lecture that night，but he had a headache.那晚他本打算带她去听一个讲座，但他因为头疼没有去。I wont tell you about it.我不想把此事告诉你。3be going to表示事先考虑的事；而will则并没有经过事先考虑，是即时的决定。此时，两者不能互换使用。(1)Why are you taking down all the pictures?你为什么把画都取下来了？Im going to repair the room.我打算修房子。(2)Where is the telephone book?电话簿在哪里？Ill get it for you.我去给你拿。4be going to可用于条件状语从句中，表示将来时间；而will用于条件状语从句时，不是表示将来时间，而是表意愿、拒绝、坚持或推论。If youre going to play tennis this afternoon，youd better get your shoes cleaned.如果打算今天下午打网球，你最好把鞋擦好。If he will listen to me，Ill give him some advice.如果他乐意听我的，我就会给他提些建议。If he wont come，well ask someone else.如果他不愿来，我们就问别的人。二、虚拟语气在非真实条件句中的用法虚拟条件句主句例句与现在事实相反的假设一般过去时(be用were)should/would/could/might 动词原形If I were you，I should seize the chance to go abroad.与过去事实相反的假设过去完成时(had过去分词)should/would/could/might have过去分词If you had taken my advice，you would not have failed in the exam.与将来事实相反的假设一般过去时were to动词原形should动词原形should/would/could/might 动词原形If it were to rain tomorrow，the sports meeting would be put off.1.错综时间条件句当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，动词的形式要根据它所表示的时间作出相应的调整。If you hadnt watched that movie last night，you wouldnt be so sleepy now.如果昨晚你没有看那部电影，现在你就不会如此困了。2if省略句在虚拟条件句中，有时可将引导条件从句的连词 if省略，而将从句中的 were, should, had等提到句首。Had he followed the doctors advice，he would regain his health now.他如果(过去)听从医生的建议，现在就恢复健康了。 3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。We couldnt have finished the work ahead of time without your help.(介词短语)(如果)没有你的帮助我们就不可能提前完工。I was ill that day.Otherwise，I would have taken part in the sports meet.(副词)我那天生病了，否则，我将会参加运动会了。I might have given you more help，but I was too busy.(连词)我本可以给你更多的帮助，但是我太忙了。1Pity you missed the lecture on nuclear pollution.I _ it，but I was busy preparing for a job interview.(2011·福建，34)Aattended Bhad attendedCwould attend Dwould have attended2The weather has been very hot and dry.Yes.If it had rained even a

invite课堂活动区感悟高考1D句意为：你错过了关于核污染的讲座真是遗憾。我本想去听的，但我忙着准备工作面试。由语境可知，此处表示“本想去而事实上没去”，为虚拟语气。叙述与过去事实相反的情况要用would have done，故D项正确。2D句意为：天气又热又干燥。是的。要是稍微下点儿雨，现在的情况就会更好一些！那样我的蔬菜就不会死掉了。由条件句中的had rained可以推出这是与过去事实相反的虚拟语气，但是主句有时间状语now，所以用了与现在事实相反的虚拟语气would be；最后一句话也是与过去事实相反的虚拟语气，故用wouldnt have died。3A句意为：如果我知道这个电脑程序，就会节省大量的时间和精力。由上句“Had I known”可知，从句为与过去事实相反的虚拟条件句，省略了if。那么主句谓语形式应为would have done。4Bshould表示“假如，万一”。如：If you should need any help，heres my number.万一你需要帮助的话，这是我的电话号码。5D句意为：要是没有他们的帮助，我们不可能及时完成那个计划。but for要是没有，句子应用虚拟语气。又因计划已经完成了，所以用“情态动词现在完成时态”表示对过去发生的事情的猜测。6D在听完第一个说话者的话之后“我不知道Ann在住院”这个情况就已经成为过去，所以要用一般过去时，因此可以排除B、C两项；我去看她这个动作发生在将来，是临时决定要去做某事，没有计划和安排性，所以用will，不用be going to结构，由此可以排除A项。故此题应该选D项。对点训练1A2.D3.A4.A5.A4
