Question

don't forget toclose the windows when you leave the room.改为反意疑问句

Answer 1

你好
该句的反义疑问句为：
Don't forget to close the windows when you leave the room，will you?（can you?)

因为该句为祈使句，翻译为别忘了走的时候关上窗户
祈使句的反义疑问句变化规则：
当陈述句是【否定的祈使句】时，问句可用will you 或 can you 。
　　e.g. Don't make much noise,will/can you?

希望可以帮助到你：）
