题目内容
4．She says that she'll have to close the shop _______ business improves．（ ）| A． | if | B． | or | C． | unless | D． | because |
分析 她说她将不得不关闭商店除非生意得以改善．
解答 答案：C．
本题考查的是从属连词的辨析．根据题意，从前半句"她说她将不得不关闭商店"和后半句"生意得以改善"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C．
点评 做这种题时，首先要根据语境及上下文确定考察范围--连词；其次根据句意确定连词；再次根据选项中的连词意思即可确定答案．
