?過去完成時態(tài)的判定方法

江西 羅煥慧

◎要點(diǎn)概述

過去完成時用來描述主語在某一過去時間或行為之前就已經(jīng)完成了的動作或狀態(tài)，側(cè)重于其在過去的過去時間里對某事造成的某種影響或結(jié)果。過去完成時由“助動詞had（用于各種人稱和數(shù)）+過去分詞”構(gòu)成。

掌握這個時態(tài)的關(guān)鍵點(diǎn)在于理解主語動作或狀態(tài)發(fā)生的時間是“過去的過去”。下面我們來學(xué)習(xí)三種判定過去完成時的方法：

一、從時間狀語來判定

一般來說，各種時態(tài)都有特定的時間狀語。與過去完成時連用的時間狀語有以下幾種：

1.by + 過去的時間點(diǎn)。例如：

①I had finished reading the novel by nine o'clock last night.到昨晚九點(diǎn),我已經(jīng)看完這本小說了。

②By the time of yesterday, we had gotten more than ten thousand letters.到昨天為止，我們已經(jīng)收到了一萬多封信件。

2.by the end of + 過去的時間點(diǎn)。例如：

①We had learned over two thousand English words by the end of last term.到上學(xué)期末，我們已經(jīng)學(xué)了兩千多個英語單詞。

②By the end of last week, they had completed the new bridge.到上周末，他們已經(jīng)完成了這座新橋。

3.before + 過去的時間點(diǎn)。例如：

①They had planted six hundred trees before last Wednesday.在上星期三之前，他們已經(jīng)種了六百棵樹了。

②My uncle had never been to Shanghai before I was born.在我出生前，我舅舅從未到過上海。

二、由“過去的過去”作判定

過去完成時表示“過去的過去”，是指在過去某一動作之前就已經(jīng)發(fā)生或完成的動作，即動作有先后關(guān)系，動作在前的用過去完成時，在后的用一般過去時。這種用法可根據(jù)以下來判定：

1.從賓語從句中判斷

當(dāng)賓語從句的主句為一般過去時，且從句的動作先于主句的動作時，從句要用過去完成時。過去完成時通常出現(xiàn)在told、said、asked、knew、heard、thought等動詞后的賓語從句中。例如：

①He said that his wife had seen the film before.他說他妻子已經(jīng)看過這部電影了。

②She asked me where I had been during the summer holidays.她問我暑假去了哪里。

2.從狀語從句中判斷

在時間、條件、原因和方式等狀語從句中，主、從句的動作發(fā)生有先后關(guān)系，動作在前的，要用過去完成時，動作在后的要用一般過去時。例如：

①After he had finished his homework, he went to bed.做完作業(yè)后，他上床睡覺了。

②I had been at the bus stop for 20 minutes when a bus finally came.當(dāng)車來的時候，我在車站已經(jīng)等了20分鐘。

【注意】由before、after引導(dǎo)時間狀語從句時，若主、從句表示的動作緊密相連，則主、從句都用一般過去時。例如：

①After he closed the door, he left the classroom.他關(guān)上門離開了教室。

②Henry visited New York before he left for Washington.亨利去華盛頓前游覽了紐約。

3.從定語從句中判斷

在含有定語從句的主從復(fù)合句中敘述過去的事情，先發(fā)生的動作用過去完成時。例如：

①She found the key that she had lost.她找到了丟失的鑰匙。

②Linda wanted to use the umbrella that her mother had bought for her before.琳達(dá)想要用她媽媽以前給她買的那把雨傘。

4.在固定句型中判斷

過去完成時還可用在hardly...when...，no sooner...than...，It was the first / second / ...time（that）...，It was...since...等固定句型中。例如：

①Hardly had John begun to speak when the audience interrupted him.約翰剛開始演講，聽眾就打斷了他。

②No sooner had he arrived than he went away again.他剛到就又走了。

③It was the third time that he had been out of work that year.這是他那一年的第三次失業(yè)了。

5.從意向性動詞上判斷

表示意向的動詞如hope、wish、expect、want、think、intend、mean、suppose等，用過去完成時表示“原本……，未能……”。例如：

①We had hoped that you would come, but you didn't. 我們原本希望你來，但你沒有來。

②Peter had meant that he could give his wife a surprise.彼得原本打算給妻子一個驚喜。

三、根據(jù)上下文去判定

當(dāng)人們敘述過去發(fā)生的事情，在已敘述了過去發(fā)生的事情后，反過來追述或補(bǔ)述以前發(fā)生的動作時，常用過去完成時。例如:

①I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.我昨天在街上遇見了王滔。自從他去北京后，我們都沒有見過面。

②Last week I talked with my cousin about my favorite novel Pride and Prejudice. It so happened that she said she had read it before.上周我和表姐談起我最喜歡的小說《傲慢與偏見》。真巧了，她說她以前正好也讀過。
