题目内容
5.You can't pass the exam if you don't work hard.(改为同义句)You can't pass the examunlessyou work hard.
分析 如果你不努力学习你就不能通过考试.
解答 答案:unless.原句是if…not表示如果不…,引导的条件状语从句,相当于unless(如果不…,除非…),故答案是unless.
点评 Unless 的条件句 表示在特定条件下,才决定做或不做一件事,中文用的连接词一般是"除非"和"否则".如:除非刮台风,否则演唱会将如期进行.在英语中,我们可以用unless表达这个意思,相当于if not.
