② 過去進(jìn)行時(shí)的時(shí)間狀語有:then, at that time, this time yesterday, at (eight) yesterday (morning),(a year) ago, 以及由when引出的時(shí)間狀語從句。如:He was cooking supper this time yesterday.(昨天這個(gè)時(shí)候他正在做晚飯)/ The little girl was playing with her toy when I saw her.(我看到小女孩的時(shí)候她正在玩玩具)

④ 也可以表示過去一個(gè)階段頻繁發(fā)生或反復(fù)進(jìn)行的動(dòng)作,常與always等頻度副詞連用,以表示贊揚(yáng)、不滿或討厭等感情色彩。如:He was always borrowing money from me when he lived here.(他住在這里時(shí)老向我借錢)

 

(6)現(xiàn)在完成時(shí) 現(xiàn)在完成時(shí)表示一個(gè)發(fā)生在過去的、對(duì)現(xiàn)在仍有影響的動(dòng)作,或表示開始在過去,并且一直延續(xù)到現(xiàn)在,甚至還可能延續(xù)下去的動(dòng)作。

①在完成時(shí)由“助動(dòng)詞have (has)+動(dòng)詞的過去分詞”構(gòu)成。

②表示發(fā)生在過去的對(duì)現(xiàn)在仍有影響的動(dòng)作時(shí),時(shí)間狀語有:already, yet, just, once, twice,ever, never,three times, before等。如:I have never seen such fine pictures before. (我以前從來沒有看過這么好的畫)/ He has just gone to England.(他剛?cè)ビ?guó))

④口語中have got往往表示have(有)的意思。如:They have got thousands of books in their library.(他們圖書館有上萬本書)

⑤have been to與have gone to的區(qū)別:have gone to(“已經(jīng)去了”)表示人不在這里,have been to(“去過”)表示人在這里。如:--Where is Mr Li? –He has gone to the UK.(李先生在哪里?他去了英國(guó)。)/ --Do you know something about Beijing? –Yes,I have been to Beijing three times. (你知道北京的情況嗎?是的,我去過那里三次。)

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)

have
(already)
gone to…
have
been in / at …
for (two years)

has
 
come to…
has
been here
since (1990)

(had)
 
left…
(had)
been away from…
 

 
 
arrived…
 
been in…
 

 
 
died
 
been dead
 

 
 
begun

ended
 
been over
 

 
 
bought...
 
had…
 

 
 
borrowed…
 
kept…
 

 
 
joined…
 
been in …
 

        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?)
