【正文】 成時(shí)的主要用法 1. 過去完成時(shí)表示一個(gè)動(dòng)作或狀態(tài)在過去某一時(shí)間或動(dòng)作之前已經(jīng)完成或結(jié)束，即發(fā)生在“過去的過去”。此時(shí)多與 already ， yet ， still ， just ， before ， never 等時(shí)間副詞及 by ， before ， until 等引導(dǎo)的短語或從句連用。 I had learned 1000 English words till then.到那時(shí)為止我已經(jīng)學(xué)會(huì)了 1000 個(gè)英語單詞。（“等”的動(dòng)作從過去某一時(shí)間點(diǎn)持續(xù)到現(xiàn)在） — John returned home yesterday. 約翰昨天回到家的。如： He entered the room, turned on the light and read an evening paper. I (had) called her before I left the office.重點(diǎn)英語中，已經(jīng)有了一個(gè)過去一般時(shí)表示在過去發(fā)生的動(dòng)作，為什么還有過去完成時(shí)呢？要記住：過去完成時(shí)的關(guān)鍵概念是：假設(shè)在過去發(fā)生了兩件(或以上)的事件，一件是A事件，另一件是B事件，如果A、B兩個(gè)事件幾乎是同時(shí)發(fā)生的，那就用一般過去時(shí)；但是，如果A、B兩個(gè)事件不是同時(shí)發(fā)生的，怎么辦呢？那就是：哪個(gè)事件先發(fā)生，就用過去完成時(shí)；哪個(gè)事件后發(fā)生，就用過去完成時(shí)。［例1］She said (that) she had never been to Paris.［例2］When the police arrived, the thieves had run away.［例3］We had hoped that you would e, but you didn39。t (先“希望”，后才發(fā)生“沒去”)［例4］……was disappointed……h(huán)ad left ……arrived (先“離開”，后“到達(dá)”和“失望”)［例5］……were writing……went ……h(huán)ad left［例1］By the time he was twelve, Edison had began to make a living by himself. 實(shí)際上，在上面的例句中，仍然有著“先、后”之分的。說他“12歲”，顯然是過去式。(當(dāng)然，我說的是很有可能。t heard from him for six month.所以此句用的是過去完成時(shí)。a phone call.7.
