题目内容
7. you are aware of the trick used in advertisements,I don't think you are eager to buy.( )| A. | Unless | B. | Whether | C. | Once | D. | Although |
分析 一旦你意识到了广告中使用的伎俩,我认为你就不会急切地想去买东西了.
解答 答案:C
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.Whether"不论,无论",引导让步状语从句;Once"一旦",引导时间状语从句;Although"尽管",引导让步状语从句.分析可知"you are aware of the trick used in advertisements"和"I don't think you are eager to buy"之间是逻辑上的"时间"关系,排除A、B、D三项,所以答案选C.
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.
