题目内容
2.Facing a beggar,I may feel this poor person needs help,and the need will not be met _____ I put my hand in my pocket now.( )A. | since | B. | in case | C. | unless | D. | while |
分析 面对一个乞丐,我会觉得这个可怜人需要帮助,而且这种需要不会得到满足,除非我现在就把手放到口袋里(掏钱).
解答 答案:C
句意表达的是条件;since因为,in case以防万一,unless除非,while然而,却;unless相当于if not,和句中的the need will not be met构成双重否定,表达肯定的意思.故选C.
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.
