1、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.

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

4、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.

5、hetherD. 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.
