题目内容
6．Work hard，and you will pass the exam．（改为同义句）If youdon't work hard，you will not pass the exam．
分析 努力学习，你就会通过考试．
如果你不努力，你就不会通过考试．
解答 答案：If，don't．原句是祈使句+and+陈述句，这里句意是努力学习，你就会通过考试．结合下文的否定，故也就是如果你不努力，你就不会通过考试．用if引导的条件状语从句，遵循主将从现的规则，从句主语you，故借助于do构成否定，故答案是If，don't．
点评 祈使句，+and+陈述句：在这里祈使句相当于if 引导的条件状语从句（但此时去掉and）．
Give blood （ if you can ）and many lives will be saved．
祈使句，+or+陈述句
Listen to the teacher carefully in class，or you can't catch what he is saying．
