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。
高考英语before 用法终结篇1. before 译为“在……之前”。
例如:Don't count your chickens before they are hatched. ( Proverb )不要在蛋尚未孵出之前先数鸡。
(勿过分指望没有把握之事。
)(谚语)We do want to buy something now before prices go up. 在物价上涨之前,我们现在的确想买一些东西。
2. before 译为“……才”。
例如:The meeting was over before he arrived. 会议结束了,他才到。
You must finish your homework before you go out to play basketball.你必须完成作业,(然后)才能出去打篮球。
3. before 译为“还没有来得及……就”。
例如:He had measured me before I could get in a word. 我还没有来得及插话,他就给我量好了。
Someone called me up in the middle of the night, but they bung up before I could answer the phone. 有人在半夜给我打电话,但我还没有来得及接,电话就被挂了。
4. before 位于表示一段时间的词语之后时,可译为“……之后”。
例如:Sun Shuwei studied hard at school and trained hard for five years before he came to the national team.孙淑伟在学校努力学习,刻苦训练, 5 年之后进入了国家队。
They worked long hours for several weeks before everything returned to normal.他们超负荷工作,几周之后,一切才恢复正常。

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)。
