题目内容
13.We will climb the mountain it rains tomorrow.( )| A. | if | B. | unless | C. | when | D. | while |
分析 除非明天下雨,否则我们将去爬山.
解答 答案:B.
本题考查的是从属连词的辨析.根据题意,从前半句"我们将去爬山"和后半句"明天下雨"来看,这里需要一个表假设的连词,主句用一般将来时从句用一般现在时说明后句是表假设的条件状语从句,结合选项,unless可以引导一个表假设的条件状语从句,意为"除非",相当于if not.故选B.
点评 比较和分析选项中连词的不同含义及其用法是解答该题的关键;还要根据句中信息正确推测该句句意,进而作出解答.
