【正文】 n,before等引出狀語從句。有時句子中會有already, just, once, ever, never等詞語,也會有for… 或since…構(gòu)成的時間狀語。如：They had already finished cleaning the classroom when their teacher came.(當(dāng)老師來的時候他們已經(jīng)打掃完了教室)/ The woman had left before he realized she was a cheat.(在他發(fā)覺那個婦女是個騙子時她已經(jīng)走掉了)③過去完成時常用于賓語從句中、after引導(dǎo)的從句中,或者從句是before引導(dǎo)的主句中。如：After I had put on my shoes and hat,I walked into the darkness.(我穿上鞋子戴上帽子走進(jìn)了黑暗之中)/ He said that he had never seen a kangaroo before.(他說他以前從來沒有見過袋鼠)(8) 過去將來時 過去將來時表示在過去預(yù)計(jì)將要發(fā)生的動作或存在的狀態(tài)。①過去將來時由“助動詞should(第一人稱)或would(第二、三人稱)+動詞原形”構(gòu)成。在美國英語中,過去將來時的助動詞一律用“would +動詞原形”。②過去將來時常由于賓語從句中,時間狀語有：later, soon, the next (day).③在時間狀語從句和條件狀語從句中不可以使用過去將來時,而應(yīng)該使用一般過去時。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€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坐下來看看書)④表示純粹的將來時用would或should,表示打算或主觀認(rèn)為的事情用was/were going to (+動詞原形)。如：She told me she would be 18 the next month.(她告訴我她下個月就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過去將來時還可以表示一個過去經(jīng)常性的動作。如：When it rained in the day, he would bring an umbrella with him.(白天下雨時他會隨身帶一把雨傘)(9)現(xiàn)在完成進(jìn)行時：現(xiàn)在完成進(jìn)行時指一個從過去就開始一直延續(xù)到現(xiàn)在并由可能繼續(xù)下去的動作,它具有現(xiàn)在完成時和現(xiàn)在進(jìn)行時雙重特征,結(jié)構(gòu)是：“have/has + been +動詞的現(xiàn)在分詞”。如：I have been swimming in the cold water for about two hours.(我已經(jīng)在冰冷的水里游了將近兩個小時)/ How long have you been waiting here?(你在這里一直等了多久？)
