3、ld 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。I wont tell you about it.我不会把此事告

4、诉你。3.be 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。Why are you taking down all the pictures?Im going to repair the room.你为什么把画都取下来了？我打算修房子。Where is the telephone book?Ill get it for you.电话簿在哪里？我去给你拿。4.be 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” 。will 还可以表示“请求、邀请”

5、 。If youre going to play tennis this afternoon，youd better get your shoes cleaned.如果今天下午打算打网球，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。.条件句条件句(Conditional)是由“条件状语从句主句”构成的复合句，分为真实条件句和虚拟条件句。一、真实条件句1.真实条件句用陈述语气，假设的情况可能发生，其中 if是“如果”的意思。条件状语从句主句 意义一般现在时shall/will动词原形未来可

6、能发生的情况一般现在时祈使句 用于向某人提出建议、命令。一般现在时一般现在时表示根据条件，经常或总是会发生的事或者真理。If it rains tomorrow，we wont have the sports meeting.如果明天下雨的话，我们就不举行运动会了。If you know the answer，put up your hands please.如果你们知道答案，请举手。If lions are hungry，they hunt other animals.如果狮子饿了，它们就猎食其他动物。2.在真实条件句中，有时也可用“unless一般现在时”谈论现在和未来要发生的事。此时 u

7、nless相当于 if.not.，但并不是任何时候它们都能互换，特别是当从句的动作或事情不发生，主句的情况才能发生时，只能用if.not.。You will not succeed unless you work hard.You will not succeed if you dont work hard.除非你努力工作，否则你就不会成功。I will be surprised if he doesnt have an accident.他要是不出事，我倒会感到奇怪。(不可用 unless)二、非真实条件句非真实条件句用虚拟语气，if 引导的非真实条件句，可以表示过去、现在和将来的情况。它的

8、基本特点是时态前移。时间 条件状语从句 主句与现在事实相反If主语did/were主语would/could/might/should动词原形与过去事实相反If主语had done/been主语would/could/might/shouldhave done/been与将来事 If主语did 主语实相反 If主语were to doIf主语shoulddo/bewould/could/might/should动词原形If I had time，I would certainly join you in the tennis match.我要是有时间肯定和你一起打这场网球比赛。(事实是：我没有

9、时间)If he had taken my advice，he might not have made such a bad mistake.要是他听进了我的劝告就不会犯这么严重的错误了。(事实是：他没有听我的建议)三、其他情况的条件句1.省略 if的非真实条件句条件句中有 were，had，should 时，可把 if省略，而把 were，had，should 放在主语前，构成倒装结构，这种结构主要用于书面语中。Were it necessary，I might resign.如果必要的话，我可以辞职。Had you informed me earlier，I wouldnt have si

10、gned the contract.要是你早点告诉我的话，我是不会签那份合同的。Should it rain tomorrow，we would have to put off the visit to the Yangpu Bridge.如果明天下雨，我们就得推迟参观杨浦大桥。2.错综时间条件句在这种虚拟语气中，主句和从句的动作发生的时间不一致。因此，主句和从句的谓语动词要根据各自所指的不同时间选择适当的动词形式。If I were you，I wouldnt have missed the film last night.(从句与现在事实相反，主句与过去事实相反)如果我是你，我不会错过昨晚

11、那场电影。If they had started in the early morning，they would arrive in half an hour.(从句与过去事实相反，主句与将来事实相反)要是他们一大早就出发的话，再过半小时就该到了。If you had asked him when you saw him last time，you would know what to do now.(从句与过去事实相反，主句与现在事实相反)如果上次你看到他时问他一下，现在就知道该怎么做了。3.含蓄条件句不是用条件句而是由介词短语(without 没有，but for 要不是)、连词(but

12、但是)、副词(otherwise 否则)等或上下文来表示某种假设的情况。Without electricity，life would be totally different today.没有电，今天的生活就完全不一样了。4.wish引导的宾语从句在 wish后的宾语从句中常用虚拟语气，从句用一般过去时，表示与现在事实相反的虚拟；用过去完成时，表示与过去事实相反的虚拟；用“would/could动词原形”表示将来不太可能实现的愿望。He wishes he were as tall as Yao Ming.他希望和姚明一样高。5.某些词后的宾语从句在 suggest(建议)，advise，or

13、der，demand(命令)，request，require，desire(要求)和 insist(坚决要求)之后的宾语从句中，谓语动词用“should动词原形” ，其中 should可以省略。Our English teacher suggests that we (should) do more English exercises.我们的英语老师建议我们多做英语练习。6.其他句式中的虚拟语气句式 动词形式 意义It is high/about time that.过去式或“should动词原形”现在该；是的时候了。过去式(表示与现在或将来事实相反的情况)I would rather tha

14、t. 过去完成式(表示与过去事实相反的情况)但愿；宁愿过去式(表示与现在或将来事实相反的情况)If only.过去完成式(表示与过去事实相反的情况)那就好了；该多好。.用所给词的正确形式填空1.If the new safety system had been put(put) to use，the accident would never have happened.(2017北京)2.Do you have Bettys phone number?Yes.Otherwise，I wouldnt have been(not，be) able to reach her yesterday.(2
