5、 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.我不会把此事告诉你。3.be goin

12、e signed 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

13、错过昨晚那场电影。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(

14、but 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)，ad

15、vise，order，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

16、 rather that. 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 we had caught(catch) the flight yesterday，we would be enjoying our holiday on the beach now.(2018天津)2.If we dont stop climate change，many animals and plants in the world will be gone(go).(2
