1.关于before的例句,简单易懂

一、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）指位置在前面，如： we knelt down before grandma's grave. 我们在奶奶的墓前跪下。 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。 二、作为连词 其基本含义是“在……之前”，又可以根据不同语境灵活翻译成“才”、“还没来得及就……”、“趁……”、“就”等。

具体用法如下： ⒈）与情态动词can/could连用 这时候从句虽为肯定形式，根据汉语表达习惯译成“还没来得及就”，如： before i could get in a word,he had measured me. 我还没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）用于肯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. 我们航行了四天四夜才看到陆地。 we waited a long time before the train arrived. 我们等了很长时间火车才到。

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 hadn't run a mile before he felt tired. 我们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. 我们刚到学校铃声就响了。

⒌）有时还有“宁愿”的意思 i'd 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根据主从句的时态分成两种情况。

若主句是一般时将来时态，从句是一般现在时.若主句是肯定句意思是“要过多长时间才”；若主句是否定形式翻译成“用不了多久就”。 it will be two weeks before everything returns to normal. 两周之后一切才能恢复正常。

it will be many years before the situation improves. 这种状况或许要过许多年才能得以改善。 it won't be long before we meet again.用不了多久我们就会再见面的。

这时若主句是一般过去时从句也是一般过去时。若主句是肯定句翻译成“多长时间之后才”，若主句是否定形式翻译成“没过多久就”。

如： it was some time before i realized the truth. 过了很长一段时间我才了解到真相。 it wasn't long before she became a brave solider. 没过多久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.。
