Technology PPT，第五部分内容：语法整体突破过去将来时一、基本构成过去将来时表示从过去某个时间看将要发生的动作或存在的状态，常用于宾语从句或间接引语中。过去将来时常用“should/would＋动词原形”或“was/were going to＋动词原形”来表达。[合作探究]　画出下列句子中的过去将来时示例：I asked if he would come and fix my TV set.①He asked me yesterday when I should leave for Paris.②They wanted to know how they would finish the homework earlier.③I wish I would go with him to the cinema tonight.④I was told that he was going to return home.⑤He said that he would wait for me at the school gate.[自主发现1]过去将来时是由“____________________________”或“____________________________”构成的。过去将来时的基本特征，即“立足过去，着眼未来”。它表示从过去某一时间来看将要发生的某个动作或存在的某种状态。但这个“将来”时间绝不会延伸到“现在”，而仅限于“过去时间区域内”。二、用法[合作探究]　He said that he would wait for us at the bus stop.他说他要在车站等我们的。Whenever we had trouble, he would come to help us.每当我们遇到困难时，他总会给予帮助。I didn’t know when she would come，but when she came I would let you know.我不知道她什么时候来，但她来了我会告诉你。The teacher said that it would be very difficult to make progress if I didn’t work hard.老师说，如果我不努力学习的话，就很难取得进步。We were going to go to the cinema when the phone rang.我们正准备去电影院，这时电话响了。[自主发现2](1)过去将来时可以表示从过去某时看来将要发生的动作或存在的状态。(2)条件状语从句和时间状语从句中须用________________代替过去将来时。(3)was/were going to do表示____________、计划做某事，或将要发生某事。[名师提醒]　表示过去的某种习惯性行为，只用____________。三、其他结构[合作探究]　I couldn’t go to Tom’s birthday party as I was about to go to hospital.我不能参加汤姆的生日晚会，因为我要去医院。He was on the point of leaving when we came in.我们进来时，他正要动身。A lot of people were coming to watch the fireworks.有许多人要来观看焰火。She told her mother that she was going to a dance with Tom.她告诉母亲，她要和汤姆一起去参加一个舞会。She said she was to take up the position.她说她要承担这个职务。The train was supposed to arrive half an hour ago.火车本应在半小时之前到达。What was meant to be a funny story fell completely flat.原欲使之成为有趣的故事，结果完全变得索然寡味。... ...
