题目内容
14.Why not look up the new word in a dictionary you don't know it?( )A. | if | B. | that | C. | though | D. | whether |
分析 翻译:如果你不认识新单词,为什么不查字典?
解答 if引导条件状语从句表示如果;that引导宾语从句,没实际意义;though引导让步状语从句表示虽然;whether引导宾语从句表示是否.根据语境和句意如果不认识.故选:A.
点评 本题考查并列连词.if表示如果引导原因状语从句,主句是一般将来时,从句要用一般现在时代替一般将来时; if或whether表示是否引导的宾语从句应和主句的时态保持一致.即主句为一般现在时,从句用任一种时态;主句为一般过去时,从句则用过去时中的任一种时态.
