2025年6月英语四级甄选语法:before的使用方法
1、可以用作介词
⒈)指时间上早于,在……之前,如:
She has lived here since before the war.
她从战前就一直在这儿住。
⒉)指地方在前面,如:
We knelt down before Grandmas grave.
大家在奶奶的墓前跪下。
⒊)指顺序或排列在之前,如:
Your name comes before mine on the list.
名单上你的名字在我之前。
⒋)在某人面前,如:
She said it before the witness.
他是当着证人的面说的。
2、作为连词
其基本含义是“在……之前”,又可以参考不同语境灵活翻译成“才”、“还没有来得及就……”、“趁……”、“就”等。具体使用方法如下:
⒈)与情态动词can/could连用
这个时候从句虽为一定形式,依据汉语表达习惯译成“还没有来得及就”,如:
Before I could get in a word,he had measured me.
我还没有来得及插话他就为我量好了尺寸。
Before she could move,she heard a loud noise,which grew to a terribl eroar.
她还没有来得及迈步,就听见一声巨响,接着就是可怕的隆隆轰鸣。
⒉)用于一定句中强调主句所表达的时间,距离长,或花费的精力大,译成“才”
We had sailed four days and four nights before we saw lands.
大家航行了四天四夜才看到陆地。
We waited a long time before the train arrived.
大家等了很久火车才到。
⒊)用于否定句中,强调主句所表达的时间,距离短,或花费的精力小,译成“不到……就”如:
We hadnt run a mile before he felt tired.
大家跑了还不到一英里他就累了。
⒋)主句含有hardly,scarcely等半否定副词时可以译为“刚……就”
这个时候主句应用过去完成时态,从句用过去时,还可以用when替代before如:
We had scarcely reached the school before/when the bell rang.
大家刚到学校铃声就响了。
⒌)有时还有“宁可”的意思
Id shoot myself before I apologized to him.我宁死也不向他道歉。
⒍)用于It+be/take+时间段+before句型
在这一句型中又可以参考主从句的时态分成两种状况。
若主句是一般时以后时态,从句是一般目前时.若主句是一定句意思是“要过多久才”;若主句是不是定形式翻译成“用不了多长时间就”。
It will be two weeks before everything returns to normal.
两周之后所有才能恢复正常。
It will be many years before the situation improves.
这种情况可能要过很多年才能得以改变。
It wont be long before we meet again.用不了多长时间大家就会再见面的。
这个时候若主句是一般过去时从句也是一般过去时。若主句是一定句翻译成“多久之后才”,若主句是不是定形式翻译成“没过多长时间就”。如:
It was some time before I realized the truth.
过了非常长一段时间我才获悉真相。
It wasnt long before she became a brave solider.
没过多长时间她就成了一名勇敢的战士。
After that it still took seven years before they got married.
他们又过了七年才结婚。
注意:当主句的谓语动词为延续性动词时,before与until有时可以互换。It was an hour before/until the police arrived.
