英语before用法小结(6篇)

英语before用法小结(6篇). 过去完成时主要有以下几点用法:篇一1、表示过去某一时间或动作之前已经发生或完成的动作或存在的状态。

句中常用by, before, when, until等词引导的时间状语。

它是以过去某一时间为起点,所以过去完成时是一个相对的时态,表示的是“过去的过去”。

只有和过去某时间或某动作相比较时才能用到它。

例如:Most of the guests had left when he arrived at the party. 当他到达晚会时,他发现大多数客人已经离开了。

2、过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下去,常与for, since等词连用。

例如:When Jack arrived, he learned Mary had been away for almost an hour. 当杰克到时,他得知玛丽已经离开快一个小时了。

3、用于并列句:一个并列句用的是过去式,如果另一个并列句表示的动作早于过去式这一动作,这时需用过去完成时。

例如:Tom flew home, but his father had already died.汤姆乘飞机回家,他的父亲却已经去世了。

4、某些动词的过去完成时表示过去未实现的希望、计划或打算。

常用的动词有hope, expect, suppose, think, want, wish等。

例如:They had hoped to be able to arrive before ten. 他们本来打算能在10点之前到达。

5、在before, after, as soon as等引导的从句中,由于这些连词本身已经表示出时间先后,所以可以用过去时来代替过去完成时。

例如:before的短语篇二comebefore被交由(法官,法庭)处理upbefore出庭面对beforethewind顺风;借风力beforetime提前;在原定时间以前lookbeforeyouleap三思而后行pearlsbeforeswine送给不识货者的宝物;暗投的明珠putthecartbeforethehorse本末倒置,因果倒置thecalmbeforethestorm暴风雨(或大动荡、激烈辩论)前的平静,预示艰难时期来临前不平常的平静期beforethemast作为普通水手beforethefact作案前pridegoesbeforeafall骄者必败havebeentherebefore全都知道;直接了解;亲眼看到notbeforetime早该发生的pridecomesbeforeafall骄者必败thelullbeforethestorm暴风雨之前的平静;预示艰难时期来临前不平常的平静期themorningafterthenightbefore次日早上themixtureasbefore原方配药accessorybeforethefact事前(或事后)从犯haveseenitallbefore熟知;了解carryallbeforeone战胜所有对手;完全成功用在含有after的主从复合句中篇三在主句谓语为一般过去时的宾语从句中,既可用一般过去时,也可用过去完成时。
