2015年綜合類職稱英語(yǔ)語(yǔ)法:八種時(shí)態(tài)的具體用法匯總
(8)過去將來時(shí)表示在過去預(yù)計(jì)將要發(fā)生的動(dòng)作或存在的狀態(tài)。
①過去將來時(shí)由“助動(dòng)詞should(第一人稱)或would(第二、三人稱)+動(dòng)詞原形”構(gòu)成。在美國(guó)英語(yǔ)中,過去將來時(shí)的助動(dòng)詞一律用“would +動(dòng)詞原形”。
②過去將來時(shí)常由于賓語(yǔ)從句中,時(shí)間狀語(yǔ)有:later,soon,the next(day)
③在時(shí)間狀語(yǔ)從句和條件狀語(yǔ)從句中不可以使用過去將來時(shí),而應(yīng)該使用一般過去時(shí)。如:He promised that he would pay me a lot if I helped him with the project.(他答應(yīng)付給我許多錢如果我?guī)椭隳莻(gè)項(xiàng)目)/ Every time when he was free,he would sit down and read some books.(每次只要他有空他就會(huì)坐下來看看書)
④表示純粹的將來時(shí)用would或should,表示打算或主觀認(rèn)為的事情用was/were going to(+動(dòng)詞原形)。如:She told me she would be 18 the next month.(她告訴我她下個(gè)月就18歲了)/ She told me that she was going to have a walk with her pet dog.(她告訴我她打算帶她的寵物狗去散步)
⑤過去將來時(shí)還可以表示一個(gè)過去經(jīng)常性的動(dòng)作。如:When it rained in the day,he would bring an umbrella with him.(白天下雨時(shí)他會(huì)隨身帶一把雨傘)
