题目内容
18.________ a child begins school,he enters a world of vicious competition where success and failure are clearly defined and measured.( )A. | Before | B. | Until | C. | Whenever | D. | The moment |
分析 孩子一开始上学就进入了一个残酷竞争的世界,在这个世界里成功和失败很清楚地被确定和衡量出来.
解答 答案:D
before之前,与句意矛盾;until直到,表示enter的动作持续到begin为止,与句意要表达的意思相反;whenever无论何时,引导让步状语从句,孩子开始上学的时间不是什么时候都可以,不符合事实;the moment用来连接从句时,表示一…就…;句意表达的是孩子一开始上学就进入了一个竞争的世界,是一个时间状语从句.故选D.
点评 从属连词是连词的一种,用来引导名词性从句和状语从句.大致可分为三大类:that(无词义,不做成分)if,whether (表达是否的意义,但不做句子成分); 连接代词:who,whom,whose,what,which,whatever,whoever,whichever(有词义,在句子中可作主语、表语、宾语);连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语).学习时,要注意区分和掌握.
