Unless weather stops me, I go for a walk every. 我每天都会去散步，除非遇上坏天气。
Our parents will be pleased with our performance as long as we try our best.小试牛刀：1、只要我们竭尽全力，父母就会满意我们的表现。
Our parents will be pleased with our performance _____ _____ ______ we try our best.2、如果人人为保护环境做出贡献，世界将会变得更美好。
______ ______ ______ _____ _______ to protectingthe environment, the world will become much more beautiful.二、if 引导的条件状语从句（1）“if 从句+祈使句”的句子。

B. “祈使句 + or + 陈述句”可以转化为 if 引导的否定条件状语从句，而且主语是第二人称。
