2013年高考英语二轮复习知识点：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.I'd like to study law at university _______ my cousin prefers geography. (2007年高考四川卷)

　　A. though

　　B. 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. (2006年高考广东卷)

　　A. as

　　B. if

　　C. when

　　D. where

　　例5.Parents should take seriously their children's requests for sunglasses ________ eye protection is necessary in sunny weather.(2004年高考上海卷)

　　A. because B. though

　　C. unless

　　D. if

　　例6._____ everybody knows about it， I don't want to talk any more.

　　A. For

　　B. Even

　　C. Since

　　D. However

　　【解析】B、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。
