题目内容
19．The art club is for members only．You can't go in you are a member．（ ）| A． | unless | B． | because | C． | if | D． | though |
分析 那个美术俱乐部只对成员开放，你是不可以进入的除非你是成员．
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"你是不可以进入的"和后半句"你是成员"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．再就是要熟记固定短语和句型．
