Ⅱ.单项填空
1.________ all of them are strong candidates，only one will be chosen for the post. (2011·陕西，19)
A.Since B.While C.If D.As
解析 while在句中意为“虽然，尽管”，引导让步状语从句。
2.—Time passes quickly，doesn’t it?
—Yes.It will be only a few months we take the 2012 College Entrance Examinations.
A.since B.after C.before D.when
解析 句意为：——时间过得真快，是不是？——是的，再过几个月我们就要参加2012年高考了。“It will be＋时间段＋before＋that...”表示“再过多长时间就……”。
3.I usually do the washing-up and leave the cooking to my wife， she’s a better cook than me.
A.unless B.even though C.as D.in case
解析 句意为：通常情况下我洗碗，我妻子做饭，因为和我相比，她是一个好厨师。as引导原因状语从句。
4.He had little education that he couldn’t teach little children. A.such；so B.so；such
C.such；such D.so；so
解析 当little作“少量”之意解释，修饰名词时，要用so...that...句型；当作“小的”之意解释，修饰名词时，要用such...that...句型。
5.—Why were you absent yesterday?
—I caught a cold， I had been walking around in the rain. A.but B.so C.and D.for
解析 句意为：——昨天你为什么缺席了？——我感冒了，因为之前我一直在雨中行走。for在这里表示原因，其他连词不符合逻辑。
备考策略
1.掌握连词意义，判断从句种类。
连词是用来连接词、短语、从句和句子的词，是一种虚词。根据在句中所起的作用，连词可分为并列连词和从属连词两类。高考复习时，要熟悉每个连词的语意和语用特征，尤其像as，since这样用法灵活的词；像before，until，unless这样不易掌握的词；像as，when，while，since，because，if，in case这些不易区分的词，要系统掌握状语从句的分类情况及各类状语从句中经常使用的连词。
2.区分常用句型结构，掌握时间状语从句。
英语中有一些表示时间的句型，容易混淆，要注意积累并且进行比较。特别要注意以下句型：It’s/It has been＋一段时间＋since...；It is/was＋具体时间点＋when...；It will be/was＋一段时间＋before...；It is/was＋时间状语＋that...等。 考点与考题
考点一 丰富多彩的“一……就……”和引导时间状语从句的名词短语 1.as soon as，once
2.immediately，instantly，directly等副词 3.on＋动名词
4.no sooner...than...，hardly/scarcely...when/before... 5.the moment，the minute，the second，the instant 6.at the sight of一看到……，at the thought of一想到……，at the sound of一听到…… 7.the hour，the day，the month，the year，every/each time，the first/second...time，next/any time等
我一看到他就知道他是我以前的朋友——亨利。(翻译)
The moment/minute/second I saw him I knew he was my former friend，Henry. 考题印证 1.The girl had hardly rung the bell the door was opened suddenly，and her friend rushed out to greet her. (2010·福建，26)
A.before B.until C.as D.since
解析 句意为：这个女孩刚一按门铃，门就突然开了，她的朋友冲出去迎接她。before在……之前，还没有……；until直到……才；as当……时候；since自从……以来。根据句意选A项。题干中hardly...before...实际上为一固定句式，意思是“刚……就……”，相当于
hardly...when...。
2.He had no sooner finished his speech the students started cheering. (2011·辽宁，29)
A.since B.as C.when D.than
解析 no sooner...than...“一……就……”，固定搭配。
3. they decide which college to go to，students should research the admission procedures.
(2010·北京，30)
A.As B.While C.Until D.Once
解析 句意为：学生们一旦决定上哪一所大学，就应该查询一下入学的程序。根据语境，这里应该用once引导条件状语从句，表示“一旦”。 考点二 before引导时间状语从句时的特殊意义
1.如果强调由before引导的从句动作发生在主句之后，汉语应译成“(……后)……才”。 2.如果主句的谓语动词是否定形式，则译成“不久”，这时从句放在句末。 3.用于before sb.knew it的习惯用语中译为“不知不觉就……”。
4.如果强调由before引导的从句动作发生之前，主句的动作已经发生，从句谓语动词可译为“还没来得及……就……”。
5.before还可译作“与其……(宁愿……)”。
没等我说什么，霍姆斯就急匆匆直奔车站了。(翻译)
Before I could say something，Homles had rushed off towards the station. 考题印证
1.John thinks it won’t be long he is ready for his new job. (2010·陕西，20)
A.when B.after C.before D.since
解析 句意为：约翰认为他不久就会为他的新工作做好准备。It won’t be long before...是一个常用的句式，意思是“不久就会……”。
2.You can’t borrow books from the school library_______ you get your student card.
A.before B.if C.while D.as
解析 before意为“……之后才能……”，符合题意。if“如果”，表示条件；while引导的时间状语从句谓语动词必须是延续性的；as侧重主从句动作同时发生。
考点三 when和while的特殊意义
when和while除了引导时间状语从句，译为“当……时”，还有以下特殊用法： 1.when可用作并列连词，意为“此时，那时”，常构成如下搭配：
be on the point of doing...when...；be about to do...when...；be doing...when...；had just done...when...。
