it was not yet eight o'clock before he arrived home.求翻译外加before用法

不到八点他就到家了.
before的用法：
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. ■巩固练习 ⒈(2004天津)It was evening ________ we reached the little town of Winchester.
