题目内容
16.I won't give you any help __ you tell me the truth.It's none of my business.( )A. | unless | B. | since | C. | as if | D. | even if |
分析 即使你告诉我真相,我也不会给你任何帮助,这不是我的事.
解答 答案D.
unless"除非,如果不",在意义上相当于if…not,因此在有些场合中unless与if…not可互换使用,引导条件状语从句.since意思是"自从…以来"时,引导时间状语从句;意思是"既然"时,引导原因状语从句.as if"仿佛,好像",引导方式状语从句.even if"尽管,即使",引导让步状语从句.分析可知前后两句话之间是逻辑上的"让步"关系,再结合句子所表达的意思可知答案选D.
点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.
