連詞before的奇葩用法
Before用作連詞本意是“在……之前”。其實(shí)它引導(dǎo)狀語從句時(shí)，不同語境下常引申為不同的含義。
1.表示“……才”，強(qiáng)調(diào)某事發(fā)生得晚或慢。
The American Civil War lasted four years _______ the North won in the end.(廣東)
A. after B. before C. when D. then
解析：答案為B。本句含義“美國南北戰(zhàn)爭(zhēng)持續(xù)了四年，北方才最終取得勝利”，可知本題應(yīng)選B。
2. 表示“……還沒來得及……就……”。強(qiáng)調(diào)從句動(dòng)作發(fā)生之前，主句動(dòng)作已發(fā)生。
—Why didn't you tell him about the meeting? (四川卷)
— He rushed out of the room _________ I could say a word.
A. before B. until C. when D. after
解析：答案為A。句意是“我還沒來得及說一句話，他就沖出了房間”。
3. 用于句型“It will/would be some time before...”句型中，表示“要過多久才…”；
其否定形式“It won't/wouldn't be some time before…”表示“過不了多久就……”。

解析：前兩個(gè)考題before 用于“It will be some time before...”句型，表示“要過多久…才…”。
考題3 before在本題中用于否定句,意為“過不了多久就會(huì)……”,再由狀語從句要用一般現(xiàn)在時(shí)的用法可知C項(xiàng)為正確答案,句意是:要不了多久我們就會(huì)知道試驗(yàn)的結(jié)果了。
4. 用于句型 “it was some time before …” 表示 “過了（多長(zhǎng)時(shí)間）才……”。其否定形式“ it was not some time before …” 意為“沒過多長(zhǎng)時(shí)間就……”。
It was some time ___________we realized the truth. （山東）
A. when B. until C. since D. before
解析：答案為D。題意是“過了一段時(shí)間我們才意識(shí)到事情的真相”。
5. 和hardly連用，表示“剛一……就……”。該結(jié)構(gòu)主句常用過去完成時(shí)，當(dāng)hardly位于句首時(shí)，要用倒裝語序.
I had hardly sat down before/when the telephone rang.
Hardly had I sat down before/when the telephone rang.
我剛一坐下電話就響了。
6. 和其它相似句型的區(qū)別
1）“It is/has been some time since sb. did...”表示“自從某人做某事已經(jīng)有多長(zhǎng)時(shí)間了”。
2）“It be +時(shí)間點(diǎn) + when引導(dǎo)的時(shí)間狀語從句”表示“某個(gè)動(dòng)作發(fā)生時(shí)，是某個(gè)時(shí)間”。主句謂語動(dòng)詞可以是一般過去時(shí)，也可以是一般將來時(shí)。

A. before B. since C. after D. when
— Did Jack come back early last night? （福建）
