Information Technology PPT，第五部分內(nèi)容：語法整體突破
過去將來時
一、基本構(gòu)成
過去將來時表示從過去某個時間看將要發(fā)生的動作或存在的狀態(tài)，常用于賓語從句或間接引語中。過去將來時常用“should/would＋動詞原形”或“was/were going to＋動詞原形”來表達(dá)。
[合作探究] 畫出下列句子中的過去將來時
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.
[自主發(fā)現(xiàn)1]
過去將來時是由“____________________________”或“____________________________”構(gòu)成的。
過去將來時的基本特征，即“立足過去，著眼未來”。它表示從過去某一時間來看將要發(fā)生的某個動作或存在的某種狀態(tài)。但這個“將來”時間絕不會延伸到“現(xiàn)在”，而僅限于“過去時間區(qū)域內(nèi)”。
二、用法
[合作探究]
He said that he would wait for us at the bus stop.他說他要在車站等我們的。
Whenever we had trouble, he would come to help us.
每當(dāng)我們遇到困難時，他總會給予幫助。
I didn’t know when she would come，but when she came I would let you know.
我不知道她什么時候來，但她來了我會告訴你。
The teacher said that it would be very difficult to make progress if I didn’t work hard.
老師說，如果我不努力學(xué)習(xí)的話，就很難取得進(jìn)步。
We were going to go to the cinema when the phone rang.
我們正準(zhǔn)備去電影院，這時電話響了。
[自主發(fā)現(xiàn)2]
(1)過去將來時可以表示從過去某時看來將要發(fā)生的動作或存在的狀態(tài)。
(2)條件狀語從句和時間狀語從句中須用________________代替過去將來時。
(3)was/were going to do表示____________、計劃做某事，或?qū)⒁l(fā)生某事。
[名師提醒] 表示過去的某種習(xí)慣性行為，只用____________。
三、其他結(jié)構(gòu)
[合作探究]
I couldn’t go to Tom’s birthday party as I was about to go to hospital.
我不能參加湯姆的生日晚會，因為我要去醫(yī)院。
He was on the point of leaving when we came in.
我們進(jìn)來時，他正要動身。
