英語(yǔ)基礎(chǔ)語(yǔ)法：過(guò)去完成時(shí)

一、構(gòu)成方法

由 had 加動(dòng)詞的過(guò)去分詞構(gòu)成。　　　

二、用法說(shuō)明

■表示在過(guò)去某一時(shí)刻或某一動(dòng)作之前已經(jīng)完成了的動(dòng)作，即“過(guò)去的過(guò)去”。如：

She said she had never been to Paris. 她說(shuō)她從未去過(guò)巴黎。

When the police arrived, the thieves had run away. 警察到達(dá)時(shí)，小偷們?cè)缇团芰恕?/SPAN>

By the time he was twelve, Edison had begun to make a living by himself. 到了十二歲那年，愛(ài)迪生開(kāi)始自己謀生。

注意：過(guò)去完成時(shí)是一種相對(duì)時(shí)態(tài)，一定要有一個(gè)作參照的過(guò)去時(shí)間或過(guò)去動(dòng)作作比較，否則，就不能用過(guò)去完成時(shí)。但下列3種情況雖然有是先后發(fā)生的兩個(gè)過(guò)去動(dòng)詞，卻同用一般過(guò)去時(shí)：

1. 先后發(fā)生的一系列動(dòng)作，但并不強(qiáng)調(diào)先后時(shí)，最后兩個(gè)動(dòng)詞用then，and，but 等連接。如：

On Saturday afternoon, Mrs Green went to the market, bought some bananas and visited her cousin. 星期六下午，格林夫人去了市場(chǎng)，買(mǎi)了些香蕉，然后去看望了她的表姐。

2. 兩個(gè)動(dòng)作是緊接著發(fā)生的，可用一般過(guò)去時(shí)。如：

When I heard the news, I was very excited. 我聽(tīng)到那個(gè)消息時(shí)，非常高興。

3. 敘述歷史事實(shí)，可用一般過(guò)去時(shí)。如：

Our teacher told us that Columbus discovered America in 1492. 我們老師告訴我們哥倫布于1492年發(fā)現(xiàn)了美洲。

■表示從過(guò)去某一時(shí)刻開(kāi)始一直延續(xù)到另一過(guò)去時(shí)刻的動(dòng)作或狀態(tài)。跟現(xiàn)在完成時(shí)一樣，也常與 how long, for three days, before 等表示一段時(shí)間的狀語(yǔ)連用。如：

When Jack arrived he learned Mary had been away for almost an hour. 當(dāng)杰克到來(lái)時(shí)，他才了解到瑪麗已經(jīng)離開(kāi)差不多一個(gè)小時(shí)了。

■表示未曾實(shí)現(xiàn)的希望或打算。表示希望或打算的動(dòng)詞，如hope, want, expect, think, suppose, plan, mean, intend等的過(guò)去完成時(shí)，后接不定式to do時(shí)，表示未曾實(shí)現(xiàn)的希望或打算，即“本來(lái)希望或打算做某事(但卻沒(méi)做) ”。如：

I had hoped to send him a Christmas card，but I forgot to do so. 我本來(lái)希望寄給他一張圣誕卡的，但我忘了寄了。

I had intended to come over to see you last night，but someone called and I couldn’t get away. 昨晚我本想去看你的，但有人來(lái)了我走不開(kāi)。

■用于下列4個(gè)特殊句型中：

1. hardly…when…, no sooner…than…

2. It/ That /This was the first time that…

3. It was+時(shí)間段+since…(from www.hz123456.com)

4. …than sb. had thought /expected /hoped /wanted等。

Hardly had I opened the door when he told me. 我剛開(kāi)開(kāi)門(mén)，他就告訴了我。
