高考英语before 的一个特殊用法
浅议before的用法

浅议before的用法作者:黄扬梅来源:《高中生学习·高二文综版》2015年第05期在高中英语学习中,before是一个较为常用的虚词,它既可用作介词又可用作副词,还可以用作从属连词。
其作为从属连词的用法是整个高中阶段语法学习的重点和难点。
近些年各地的高考都倾向于考查这一用法。
现将其作为从属连词的用法归纳如下:1. 表示“在……之前”,用来说明主从句所描述动作发生的顺序。
Mary had cleaned the classroom before she went home.Mary在回家之前已经将教室打扫干净了。
(before在这里表示Mary是先打扫教室,然后才回家。
打扫教室的动作发生在回家之前。
)They had got everything ready before I arrived.在我到达之前他们已经把一切都准备好了。
例1 ;You must learn to consult your feeling and your reason ; ; ; ; ; ; ; ; ; ;any decision. (reach)(2013年高考湖南卷)在做决定前,你一定要学会考虑自己的感觉与理智。
解析 ;before you reach。
这里是指要先考虑到自己的感觉和理智,然后再做决定。
2. 表示“过了……之后……才……”,强调从句的谓语动词所表达的时间、距离很长或花费较大。
She and her family hid away for nearly twenty-five months before they were discovered.她和她的家人躲藏了近25个月才被发现。
They worked day and night about three days before everything returned to normal.他们不分昼夜地工作了三天直到一切恢复正常。
3.表示“还没来得及……就……”,目的在于强调从句所表示的动作发生之前,主句动作就已经发生,着重体现主句谓语动词所表达的时间、距离短或花费的精力较小,常与情态动词can/could连用。

高中英语新高考语法基础版一轮复习讲义(17)before、after引导的时间状语从句的用法知识点整理总结

2021届高中英语新高考语法基础版一轮复习讲义(17)before/after引导的时间状语从句的用法知识点整理总结今天我们继续学习时间状语从句的引导词before和after。
二者的时态问题是困扰很多同学的难点,今天我就重点来谈谈。
01 before/after用法概述b e f o re/af te r引导时间状语从句,表示主从句的时间顺序:“在…之前”或“在…之后”。
二者时态主要有以下2种情况:主将从现01当主句是一般将来时(或祈使句、含有情态动词的句子)时,从句一般用现在时(一般现在/现在进行/现在完成)。
这种主从句时态关系一般称为“主将从现”。
如:It won't be long before we meet again.我们后会有期!He will be a teacher after he graduates from college.他大学毕业后将去做教师。
主过从过02当主句和从句的动作都是过去,且二者发生时间相同或前后差别不大时,主从句都用一般过去时;如果要强调一个在另一个之前,那么就要用过去完成时(也即两个过去)。
如(仅以before举例,after例子见后):He worked in Beijing before he came here.他来这里之前在北京工作!He had studied Chinese for one year before he came to China.他来中国之前学了一年中文。
02 before的用法before除了基本的表示“在…之前”的意思外,还能表示以下几种意思:表示“还未…就…”,主从都用一般过去时这种情况下,before强调主句动作较从句动作发生的过早或过快。
但时间相差不大,因此主从句都用一般过去时。
He called me up at midnight but hung up before I could answer it.我还未来得及接电话,他就给挂了。
since,before,when,after等的区别

高考英语常考句式——it is +时间 + since (before, when)…请注意以下三个句式的区别和意思上的差异(其中的 is 根据情况可以有其他时态形式):It is + 时间段 + since…的意思是“自从……以来有一段时间了”。
It is + 时间点 + when…的意思是“当……的时候时间是……”。
It is + 时间段 + before…的意思是“在……之前有一段时间”。
请看以下用例:It’s ten years since they got married. 他们结婚到现在已经十年了。
It was past one o’clock when he came in. 他回来时已经一点多了。
It won’t be long before they understand each other. 过不了多久他们就会互相了解的。
有时翻译可以比较灵活:It’s a long time since I met you last. 好久不见了。
(直译:自上次见到你以来有很长一段时间了。
)It’s about three years since I last played basketball. 我差不多有三年没有打篮球了。
(直译:自从我上次打篮球以来已差不多有三年了。
)请看有关高考题(答案为DDBCDC):1. That was really a splendid evening. It’s years _________ I enjoyed myself so much. (安徽卷)A. whenB. thatC. beforeD. since2. It was some time _________we realized the truth. (山东卷)A. whenB. untilC. sinceD. before3.—Did Jack come back early last night?—Yes. It was not yet eight o’clock _________he arrived home. (福建卷)A. beforeB. whenC. thatD. until4.

高考英语before 的一个特殊用法
邢丽芳
经过多年的高三教学,我觉得before 这个词的用法让很多学生都感到棘手,通过试题评讲,我从中收集了不少关于before的例句,在此我给同学们作个总结:
1. 之前
Tom’s father had died before he came back.
在汤姆回来之前,他父亲就已经死了。
2. 之后(才)
It will be many years before the chemicals start to escape from the containers . (SEFCIIIA)要过很多年之后,这些化学物品才开始从容器中流出来。
3. 不等……就
Someone called me up in the middle of the night , but he hung before I could answer the phone. (NMET 2000)
半夜有人给我打电话,但还没等我去接,对方就挂断了。
在以上这些意思中,我着重讲讲第2个意思:
一. 在时态上
主句的时态可以是将来时,也可以是过去时,但从句的时态,要么是一般现在时,要么是一般过去时,根据具体情况而定。
It will be 2 years before we graduate from the middle school.
两年之后,我们才中学毕业。
It was long before he began to do his homework.
过了很长时间,他才开始做作业。
二. 在句式上
主句不仅有肯定式,也可有否定式。
肯定结构意义为:过多久才,需要多久才;否定结构意义为:不久就……
It was long before they finished their task.
过了很长时间,他们才完成任务。
It wasn’t long before the people took up their arms.
不久,人民就开始拿起了武器。
三. 在用词上
在句型“…long before ”中,long也可换成hours , day , weeks , some time 等。
It will be hours before he arrives.
要过好几个小时他才会到。
It will be 2 weeks before we meet again.
两个星期后我们还会再次见面。
It will be some time before we know the full result.
还要过一些时间我们才能知道全部结果。
四. 在句型对比上
before 的这一用法与since等词用法很容易混淆,值得注意。
1. It has been 5 years _______ my sister returned from abroad.
2. It is 5 years ago _____ my sister returned from abroad.
3. It was the years 1990 _______ my sister returned from abroad.
4. It will be 5 years _______ my sister returns from abroad.
A. before
B. since
C. that
D. when
1. 我姐姐回国已有五年了。
(B)
2. 我姐姐是在五年前回国的。
(C)
这是一个强调句型,如果还原的话应该是:My sister returned from abroad 5 years ago.
本句就是针对5 years ago 进行强调而得来的。
3. 我姐姐于1990年回国。
(D)
本句中“it”指时间。
再如:
It was 5 o’clock when he came back.
4. 要过五年我姐姐才回国。
(A)。
