⑥在完成時(shí)中,一個(gè)瞬間性動(dòng)詞(一次性動(dòng)作)不能與表示一段時(shí)間的狀語連用,此時(shí)須將該瞬間動(dòng)詞改為延續(xù)性動(dòng)詞或狀態(tài)動(dòng)詞。具體變化見下表：
瞬間性動(dòng)詞的完成時(shí)
→
延續(xù)性動(dòng)詞或狀態(tài)動(dòng)詞的完成時(shí)

或者使用下面這個(gè)句型：
It is / has been + (多久)+ since + 主語(人)+謂語(過去時(shí))+……+過去時(shí)間狀語
[注意] 在其它的時(shí)態(tài)中也存在類似問題,記住,關(guān)鍵是：瞬間動(dòng)詞不能和表達(dá)一段時(shí)間的狀語連用。如：How long may I keep the book?(這本書我能借多久？)(句子中keep取代了borrow)
(7) 過去完成時(shí) 過去完成時(shí)表示過去某一時(shí)間或某一動(dòng)作發(fā)生之前已經(jīng)完成的動(dòng)作。簡(jiǎn)言之, 過去完成時(shí)所表示的時(shí)間是“過去的過去”。
①過去完成時(shí)由“助動(dòng)詞had+動(dòng)詞的過去分詞”構(gòu)成。
②過去完成時(shí)時(shí)間狀語有：by (yesterday), by then, by the end of (last…)或者由when,before等引出狀語從句。有時(shí)句子中會(huì)有already, just, once, ever, never等詞語,也會(huì)有for… 或since…構(gòu)成的時(shí)間狀語。如：They had already finished cleaning the classroom when their teacher came.(當(dāng)老師來的時(shí)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(gè)婦女是個(gè)騙子時(shí)她已經(jīng)走掉了)
③過去完成時(shí)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(shí) 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)常由于賓語從句中,時(shí)間狀語有：later, soon, the next (day).
③在時(shí)間狀語從句和條件狀語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)
(9)現(xiàn)在完成進(jìn)行時(shí)：現(xiàn)在完成進(jìn)行時(shí)指一個(gè)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(dòng)作,它具有現(xiàn)在完成時(shí)和現(xiàn)在進(jìn)行時(shí)雙重特征,結(jié)構(gòu)是：“have/has + been +動(dòng)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(gè)小時(shí))/ How long have you been waiting here?(你在這里一直等了多久？)
