2、愿望、假设或推测等；如 : If I were you, I should study English. 祝您胜利！二、虚拟语气在条件从句中的用法假如我是 你,我就学英语了； May you succeed. 条件句有两类, 一类是真实条件句,一类是虚拟条件句；假如假设的情形是有可能发生的,就是真实条件何； 在这种真实条件句中的谓语用陈述语气；如 : If it doesn t rain tomorrow, we will go to the park. 假如明天 不下雨,我们就去公园；假如假设的情形是过去或现在都不存在的,或将来不大可能发生的,就是虚拟条件句；如: If he had see
