He is not interested in classical music. 2. 祈使语气 ：用来表示请求、邀请、命令、警告或劝告等（动词常用原形） Don’t be late ！ 3. 虚拟语气：表示说话人所说的不是事实，而是一种假设、愿望、怀疑或推测。 一、虚拟语气在 if非真实条件句中 虚拟条件 从句 (If) 主 句 与 现在 事实相反的假设 与 过去 事实相反的假设 与 将来 事实相反的假设 主语 +did/were 主语 + should / would/ could / might + do 主语 + had done 主语 + should / would/ could / might + have done 主语 + 1.did 2. should do 3. were to do 主语 + should / would/ could / might + do If you had studied hard before, you would have passed the exam. 1. 如果我是你，我会接受他的建议。 2. 如果明天下雨，我会待在家里。 3. 如果你以前好好学习， 你会通过考试的。 If I were you, I would accept his advice.
