2017高考英语重点语法：高考英语常考语法总结——连词（附习题）

数词一般与其它知识综合起来考察，比如倍数的表达方法，多个形容词的排列顺序等。近几年语境综合化程度越来越高。 连词按其性质,分为并列连词和从属连词,考点分布在单项选择､完形填空和短文改错中｡《英语教学大纲》和《考试大纲》语法项目表中对连词的考查是这样描述的:掌握词汇表中所列连词的用法｡即要求考生分析句子成分,把握语境和逻辑关系,恰当选择合适连词,使句意通顺,逻辑清楚｡连接代词或连接副词用于名词性从句,统称连接词｡ 连词考点透析 考点一、､特殊并列连词while/when 例1. I had just stepped out of the bathroom and was busily drying myself with a towel _______ I heard the steps. (2006年高考湖南卷) A. while B. when C. since D. after 例2.I’d like to study law at university _______ my cousin prefers geography. (2007年高考四川卷) A. thoughB. as C. while D. for [解析]B､C｡作并列连词时,when/while用法较为特殊,二者区别是:while表两相对照;而when表突然､在那时,常见于be about to do...when和hardly...when等句型中｡ 考点二、表示原因的连词for/because/as/since 例3.He found it increasingly difficult to read, _____ his eyesight was beginning to fail.(2006年高考北京卷) A. and B. for C. but D. or 例4.Jenny was very sad over the loss of the photos she had shot at Canada, _____ _ this was a memory she especially treasured.

A. For B. Even C. Since D. However [解析]B､A､A､C｡引导原因连词,as/because/ since/ for的区别是:because语势最强,用来说明人所未知的原因,回答why提出的问题,可置于强调句中且其前可加修饰语; since是双方都知晓原因或经过分析而得之的原因,语气次之;for是并列连词,前用逗号隔开, 表逻辑推理或补充说明;as语气最弱,原因是显而易见的或已为人们所知,即已知原因,所引导的分句可置于句首｡ 考点三、并列连词but/yet/though 例7. Excuse me for breaking in, ______ I have some news for you. A. so B. and C. but D. yet [解析]C｡but和yet 是连词,可等同使用,但也有区别｡yet与and连用,构成and yet,但but却无此用法;在“Excuse me/I’m sorry/I hope you don’t mind…but”中,只用but,不用yet｡因为在表示对照或对立时,but较为轻松自然;而yet却较为强烈,常出人意料;though作并列连词时,只能引导分句且其前须加逗号｡例:I’ll try to come, though I don’t think I shall manage it. 考点四、引导名词性从句的从属连词that/whether/if 例8.The traditional view is ______ we sleep because our brain is “programmed” to make us do so. (2007 年高考上海卷) A. when B. why C. whether D. that 例9.We haven’t settled the question of _____ it is necessary for him to study abroad. ( 2006年高考江苏卷) A. if B. where C. whetherD. that [解析]D､C｡引导名词性从句的从属连词that与whether的区别是:句子成分完整且表意确定时选用that连接,句意不确定时选用whether/if连接;借助it,将真正主语或宾语后置,构成“It…that”句型,但whether/if不可;下列情形用whether不用if:与or not 连用,中间无其他词隔开;作介词宾语;在主语从句､表语从句和同位语从句中｡例: Whether we’ll go camping tomorrow depends on the weather. 考点五、表示比较的从属连词what/as 例10. Engines are to machines __ ____ hearts are to animals. (2006年高考山东卷) A. as B. that C. what D. which 例11._____ I explained on the phone, your request will be considered at the next meeting.(2005年高考浙江卷) A. WhenB. After C. As D. Since 例12.What a table! I’ve never seen such a thing before. It is ________ it is long.(2005年高考湖北卷) A. half not as wide as B. wide not as half as C. not half as wide as D. as wide as not half [解析]C､C､C｡what用作从属连词,表比较,用于A is to B what C is to D结构中;而as表示原级比较,常用于as...as结构中,程度修饰语应置于第一个as之前,嵌入的形容词或副词使用原级｡另外as还表“正如､按照”,引导方式连词｡ 考点六、表示条件的从属连词if /unless/as long as/once 例13. ________ I know the money is safe, I shall not worry about it. A. Even thoughB. UnlessC. As long asD. While 例14.Small sailboats can easily turn over in the water ____ they are not managed carefully.(2007年高考上海卷) A. though B. before C. until D. if 例15.You will be successful in the interview ____ you have confidence. (2007年高考福建卷) A. before B. once C. until D. though 例16.I won’t call you, _____ something unexpected happens.(2007年考全国卷) A. unlessB. whether C. becauseD. while [解析]C､D､B､A｡表条件的连词if/unless/as long as/unless在用法上存在一些差异｡as long as用法同only if/on condition that,强调某事的发生以另一事件的发生为前提;if为正面条件,可能会产生好的或坏的结果,若 某种条件产生坏的结果,此时的if可用as long as替换; unless为反面条件,表示除非,如果不,故在真实条件句中常和if…not换用;once既表时间,又包含条件,译作一旦｡ 考点七、表示让步的从属连词although/when/while 例17. We had to wait half an hour _______ we had already booked a table. (2007年高考辽宁卷) A. sinceB. although C. until D. before 例18.______I really don’t like art, I find his work impressive. (2007年高考山东卷) A. As B. Since C. If D. While 【解析】B､D｡although/when/while均可表示让步,后两者的用法较为特殊｡although/though引导让步连词时不与but和y et连用;而while却表示“部分接受,但并非全部”,或用于“强调两种情况､活动等之间的差距”;when也可表示虽然,尽管,同even if,常置于句末｡
