题目内容
20.Pandas are facing danger!The situation won't change humans stop killing.( )| A. | unless | B. | though | C. | if | D. | after |
分析 大熊猫面临濒危,这种情况不会得以改变除非人类停止猎杀.
解答 答案:A.
本题考查的是从属连词的辨析.根据题意,从前半句"这种情况不会得以改变"和后半句"人类停止猎杀."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A.
点评 本题主要考查连词的用法,做此类题目一定要弄清句意,明白上下文之间的关系,才能更好地判断出所要用的连词.
