before用法归纳

before用法知多少? 在高考中,状语从句是每年高考单项填空部分必考的题目之一,考查的重点是考生容易混淆并且近似的连词在逻辑行文和语篇结构中的使用。before作连词的用法一直是高考的重点,也是学生感觉掌握起来比较头疼的地方。下面选取近几年各省市的高考试题进行归纳分析,使考生通过典型实例,把握高考对before所引导的句型的命题规律,帮助同学们更好地解答此类题目。 1. before作为连词时的基本意义是“在……之前”,用于表示时间或顺序。 You can’t borrow books from the school library ______ you get your student card. (2009上海,32) A. before B. if C. while D. as 【解析】选A。考查连词,该句的意思是:在你得到你的学生卡之前你不能从学校图书馆借书。before表示先后顺序。 2. 表示“过了多久才……”,说明主句的持续时间比较长而从句的动作缓缓来迟。 (1) The American Civil War lasted four years _______ the North won in the end. (2005广东,30) A. after B. before C. when D. then 【解析】选B。本题考查连词before表示“在多久之后才……”的用法,根据本句含义“美国南北战争持续了四年,北方才最终取得胜利”,可知本题应选B。 (2) Several weeks had gone by I realized the painting was missing. (2004宁夏,39) A. as B. before C. since D. when 【解析】选B。before表示“过多久才……”。句意:几个星期已经过去了,我才意识到油画丢了。内含的意思是油画丢了好几个星期了,我才意识到。 3. 表示从句动作还没来得及发生或完成,主句动作就已经发生或完成了,意为“尚未……就”,“没来得及……就”,常用于before sb. can/ could…。 —Why didn’t you tell him about the meeting? ( 2006四川,35) — He rushed out of the room _________ I could say a word. A. before B. until C. when D. after 【解析】选A。本题考查连词before表示“还没来得及……就……”的用法。句意为:我还没来得及说一句话,他就冲出了房间。 4. 表示“以免,以防,趁……还没有……”,强调动作的必要性,以避免或防止从句动作的发生。 He made a mistake, but then he corrected the situation _____ it got worse.(2003北京) A. until B. when C. before D. as 【解析】选C。由made a mistake和转折词but可知本题句意是“他犯了一个错误,但在事情进一步恶化之前他改变了形势。”故答案正确答案为C项。

but,than引导定语从句和before,until用法辨析

but和than引导定语从句的用法 一、but可被看作关系代词,引导定语从句,在句中作主语,在意义上相当于 who not或that not,即用在否定词或具有否定意义的词后,构成双重否定。 如:①There is no mother but loves her children.没有不爱自己孩子的母亲。 ②There was no one present but knew the story already.在场的人都知道这个故事。 二、than作关系代词时,一般用在形式为比较级的复合句中,其结构为形容词比较级(more)...than+从句,than在从句中作主语,相当于that,代表它前面的先行词。(这时,它兼有连词和代词的性质,也有学者认为这种用法的than是连词,后面省略了主语what。) 如:①The indoor swimming pool seems to be a great deal more luxious than is necessary.室内游泳池过于豪华。 ②He got more money than was wanted.他得到了更多的钱。运用上述知识翻译下列句子: 1.任何人都喜欢被赞扬。(but) 2.我们大家都想去桂林。(but) 3.没有人不同情那些嗷嗷待哺的孩子。(but) 4.我们班上没有一个人不想帮你。(but) 5.无论多么荒凉,多么难以行走的地方,人们也能把它变成战畅(but)6.这件事情比想象的要复杂。(than) 7.这个广告的效果比预想的要好。(than) 8.这个问题看起来容易,实际上很难。(than) 9.他爸妈给他的零用钱总是超过他的需要。(than) 10.因为这项工程非常困难,所以需要投入更多的劳动力。(than) 答案: 1.There is no one but likes to be praised. 2.There is no one of us but wishes to visit Guilin. 3.There is no man but feels pity for those starving children.4.There is no one in our class but wants to help you. 5.There is no country so wild and difficult but will be made a theatre of war. 6.This matter is more complex than is imagined. 7.This advertisement is more affective than is expected. 8.The problem may be more difficult in nature than would appear.9.He got more pocket money from his parents than was demanded.

A. when B. until C. since D. before 解析:答案为D。before用于句型“it was +时间段+ before …” 表示“过了(多长时间)才……”。该题题意是“过了一段时间我们才意识到事情的真相”。故正确答案为C项。 表示“在……之后……才”。副词“才”在汉语中强调某事发生得晚或慢。如果在含有before从句的复合句中,强调从句动作发生得晚或慢时,就可以应用这种译法。 The American Civil War lasted four years _______ the North won in the end. A. after B. before C. when D. then 解析:答案为B。本题考查连词before表示“在……之后才……”之的用法,根据本句含义“美国南北战争持续了四年,北方才最终取得胜利”,可知本题应选B。 三、表示“……还没来得及……就……”。目的在于强调从句动作发生之前,主句动作已发生。 —Why didn't you tell him about the meeting? — He rushed out of the room _________ I could say a word.

Before用作连词时

Before用作连词时,意思是“在……之前”。(注:此为核心概念,其它皆是繁衍派生之义)其实,它引导状语从句时,在不同的句式中以及汉英表达习惯的不同,before含有不同的含义和用法。(注:翻译意思不同而已)。(注:当主从句动作有先有后的时候,用before,after居多,但其他的呢?居多是多少?有什么使用条件?) (最容易错的就是和when难以区分,这主要是受到中文翻译法的影响,但如何辨别?) 从历年的高考试题可以看出,before是高考考查的热点词汇之一。为了帮助大家掌握,现就对它的用法归纳如下: 一、表示“在……之后……才”。副词“才”在汉语中强调某事发生得晚或慢。如果在含有before从句的复合句中,强调从句动作发生得晚或慢时,就可以应用这种译法。 【典型考例】 The American Civil War lasted four years _______ the North won in the end.(2005广东) A. after B. before C. when D. then 解析:答案为B。本题考查连词before表示“在……之后才……”之的用法,根据本句含义“美国南北战争持续了四年,北方才最终取得胜利”,可知本题应选B。 (注:这种题目比较难,因为学生如果用中文翻译成“当”when的时候,句子也读得顺,如果来明显区分?) 二、表示“……还没来得及……就……”。目的在于强调从句动作发生之前,主句动作已发生。 【典型考例】 —Why didn't you tell him about the meeting? ( 2006四川卷) — He rushed out of the room _________ I could say a word. A. before B. until C. when D. after 解析:答案为A。本题考查连词before表示“……还没来得及……就……”的用法。句意是“我还没来得及说一句话,他就冲出了房间”。 三、表示“在……之前就……”。这时主句与before从句中的两个动作按时间

辨析before和since

辨析before和since 先看下面两道试题: 1、What was the party like? Wonderful .It’s years I enjoyed myself so much. (NMET93) A.after B.before C.when D.since 2、She was so interested in the book that she had read it for three bours she realized it. A.when B.sunce C.before D.until 在1题中,上下文提供人语言环境是:说话个方想询问另一方对晚会飞感受,另一方表达的一丝丝“晚会很精彩,自我上次玩得很开心以来已有好几年了。”,时间的计算式从since从句飞完成或状态结束时算起。因此应该选择D。 在2题中,上下文透露的语言信息是:在她意识到时间问题之前,时间已不知不觉飞过了三个小时。也就是说三小时之后从句中的动作才开始。答案应该选择C。一、若表示“还未……就……”“不到……就……”“……才……”,“趁……还没来得及”是,需用连词before,此时从句中的谓语动词不能用否定时。如We had sailed four days and four nights before we saw land.我们航行了四天四夜才看到陆地。We hadn’t run a mile he felt tired.我们没跑到一英里,他就累了。Please write it down before you get in a word, had measued me.我还没来得及插话,他就给我量好了尺寸。Before they reached the station, the train had gone.他们(还没)到火车站之前,火车已开走了。 二、在“It+be+一段时间十before从句”句型中,如果主句为一般将来时,从句常用一般现在时;如果主句为一般过去时,从句则常用一般过去时。如: 1、It will be six years before we again. A.will meet B.meet C.met D.have met (答案为B) 2、It not long before he told us about the af-fair. A.will be B.is C.had been D.was (答案为D) 除此以外,“It will be + before sb. does”还表示“多久之后才……”。如:It will be half a year before I come back.我半年后才回来。It won’t be long before we meet again.不久,我们又会见面的。 三、在“It+be+一段时间+since从句”句型中,如果主句为一般现在时或现在完成时,从句常用一般过去时;如果主句为一般过去时,从句则常用过去完成时。如:They asked me to have a drink with them. I said it was at least ten years since I a good drink. (MET’88) A.had enjoyed B.was enjoying C.enjoyed D.had been enjoying (答案为A) 四、在“It is+时间+since从句”句型中,时间的计算根据since从句中的谓语动词的情况进行推算,瞬间动词(如:break out,join,cach等)是从动作发生时算起,延续行动词,(如:smoke,work,live,have等)是从动作结束时算起。如:It is three years since the War broke our. (从break out 动作发生时算起)战争爆发以来,有三年了。It is three years since she was in our class.她离开我们班哟三年了。It is five years since I (have)smoked a cigar.(=since I stopped smoking a cigar.) (从smoke动作结束时算起)我不吸烟有五年了。如果译成“我不吸烟有五年了”,应为:It is five years since I began to smoke. 五、综合练习 1、The next moment, she had time to realize what was happening,she was hit over the head. A.when B.before C.since D.as 2、—Why didn’t you try your best to get on the bus? —I tried to,but I could,it started moving. A.until B.when C.before D.after
