高考英语一轮备考语法练习4之数词与连词Word版

专题四 数词与连词 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.Id 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BC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. forC. 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BAAC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Cbut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/Im sorry/I hope you dont mindbut”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:Ill try to come, though I dont 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.

( 2006年高考江苏卷) A. if B. where C. whetherD. that 解析DC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“Itthat”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 well 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.

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CCCwhat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 wont call you, _ something unexpected happens.(2007年考全国卷) A. unlessB. whether C. becauseD. while 解析CDBA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ifnot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 dont like art, I find his work impressive. (2007年高考山东卷) A. As B. Since C. If D. While 【解析】BDalthough/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yet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【精选试题】 名校模拟题及其答案1China won 100 medals in the Beijing Olympic Games，which are almost those of the sydney Olypic GamesA. twice as many as Bas many as twice Cas much as twice D twice as much as2 Hawking became world-famous in 。A his thirties in the 1970s Bthe thirties in his 1970 Chis thirties in 1970s Dthe thirties during the 19703Wed better hurry up of the time used up.
