题目内容
11.Double ovens are a good idea,especially ________ you are cooking several meals at a time.( )A. | though | B. | if | C. | that | D. | unless |
分析 双烤箱是一个好主意,尤其是如果你一次做几顿饭.
解答 答案B.
though尽管,引导让步状语从句; if 如果,引导条件状语从句; that引导定语从句或名词性从句,不用来引导状语从句; 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.分析可知前后两句话之间是逻辑上的"条件"关系,可排除A和C;再结合句子所表达的意思"如果你一次做几顿饭"可排除D;故答案选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.
