题目内容
10．__________ bad weather stops me，I can do outdoor sports every day．（ ）| A． | When | B． | Because | C． | If | D． | Unless |
分析 除非恶劣的天气阻拦我，否则我每天都做户外运动．
解答 答案：D．
本题考查的是从属连词的辨析．根据题意，从前半句"恶劣的天气阻拦我"和后半句"我每天都做户外运动．"来看，这里需要一个表假设的连词，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D．
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．
