关于"but"的用法
　　中国人喜欢使用"but"从句：同中文一样，在英文中这也是连接两个短句的简单方法。要避免单一的"but"从句，可以考虑采用以下这些变化形式：

　　关于"if...then"和"if"从句
　　除了"but"从句，很多学英语的人还会过多使用"if … then"或是"if"从句。这些从句本身并不是不好。但我们这里讨论的是多样性及其必要性。看看下例：
　　Before: If you fail to pass the drug test, we will have to dismiss you from your job.
　　After: Failure to pass the drug test will result in job dismissal.
　　修改后的句子语气显得稍强一些。同时因为句中省掉了"you"，使句子在语气上减少了对抗性。这个解题对策适用于每种人称，不单单指"you"。
