5、 foundation of New China,skyscrapers had rarely been seen.2.In the 1990s,with the development of our economy,many high-rise buildings were being constructed.3.However,the high-rise buildings in the city will definitely be experiencing more changes.过去完成时的被动语态1.过去完成时的被动语态是过去完成时和被动语态的叠合，表示在过去某一时间或某个动作之

6、前已经完成的动作。其基本形式为 had(not)been+过去分词。常用的时间状语为by then,by the end of last term,by the time he came back，即by+过去的时间点。下面两种情况一般用被动语态：一是强调动作的承受者。例如：“The pen had been broken by the boy before it was found.”在大家发现之前那支钢笔就被那个男孩弄坏了。二是不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者。例如：“The task had been completed before noon yesterday

7、.”那项任务昨天中午之前就完成了。2.过去完成时的被动语态与现在完成时的被动语态的区别：前者表示某个动作相对于过去来说已经被完成，后者表示某个动作相对于现在来说已经被完成。例如：She said her song had been translated into Spanish.她说她的歌曲已经被翻译成了西班牙语。例如：The book has been translated into 37 languages.这本书已经被翻译成了37种语言。过去进行时的被动语态1.过去进行时的被动语态表示在过去某时刻或者某阶段正在进行的被动动作,其基本形式为was/were(not)+being+过去分词。

8、常与then,at that time,at this/that time yesterday,at that moment等时间状语连用，但在很多情况下，没有表示时间的状语，需要通过上下文来推断。例如：We couldnt use the reading room.It was being repaired.我们不能使用阅览室，它正在修缮。2.过去进行时的被动语态和一般过去时的被动语态的区别：When I hurried to the store,I saw that the books were already being packed into boxes.When I hurried

9、to the store,I saw that the books were already packed into boxes.第一句表达了动作“打包装箱”在“我”到达书店时正在进行，而第二句表达 动作“打包装箱”在“我”到达书店时已结束。也就是说，过去进行时的被动语态强调动作的过程，一般过去时的被动语态强调动作的结果。3.过去进行时一般不与表示一段时间的状语或者表示次数的状语连用。与表示一段时间或者次数状语连用时，要使用完成时的被动语态。例如：The campus over there has been built for three years.The car has been repa

10、ired twice.He had been there for nearly ten hours.Justice had been done even before the man was handed over to the police.将来进行时1.将来进行时的基本形式为“shall/will(not)be+现在分词”。它的常见用法有三个：一是表示将来某一时间正在进行的动作，一般与表示将来的时间状语连用，如next week,this evening,at this time tomorrow,tomorrow evening等。例如：He will be giving a speec

11、h at this time tomorrow.二是表示按照计划或安排即将要发生的动作。例如：I will be having a talk with her next week.三是表示预料不久要发生的事情，或将来的某种可能性，说话人往往想表达“我料想”或“我估计”的含义。例如：After you drink the water,you will be feeling better.2.现在进行时也可以表示将来的动作，此时其与将来进行时的区别在于:将来进行时通常表示正常过程中会发生的动作，而现在进行时表示有计划的、将来肯定要进行的动作，因此相对而言将来进行时意味着动作发生的偶然性要大一些。例

12、如：Ill be seeing Peter tomorrow.明天我会见到Peter。这句话表示按照常理说话者明天会见到Peter。Im seeing Peter tomorrow.明天我要和Peter见面。这句话表示说话者已经和Peter约好了，明天肯定会见面。Step 4:Language practiceTask 1 Finish the translations of the following sentences with the given information.5.6.4.3.1.2.资料1.我明天晚上不能看电视里的演唱会，因为那时我正在做作业。I wont be able t
