题目内容
7. we can't remove our troubles in life for ever,we can leave them behind when we are on vacation.( )A. | When | B. | While | C. | Unless | D. | Until |
分析 虽然我们不能永远地消除我们生活中的麻烦,但是当我们度假的时候我们可以抛开它们.
解答 答案B.
when"在…时候",引导时间状语从句.while表示"当…的时候",引导时间状语从句;意为"尽管、虽然",引导让步状语从句;意为"而、但是",引导比较状语从句.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.until"直到",引导时间状语从句.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B.
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.
