Question

非谓语动词,什么时候用done,什么时候用being done?

能不能具体点，举几个例子我们资料上没有归纳老师也没说把用的情况都列举出来更好谢谢了！

Answer 1

总的来说他们都是表示被动,前者是做后置定语或者是表示一种状态.如;The thief was caught with his hands ,fastened back.是前者. 手和捆是被动. The building which is being built is our new classroom.是后者.又如,the man you caught is innocent.人和抓是被动关系. Given a sound beat,the boy lowered his head with shame. the boy 和give 是被动的关系.后者是被动语态的进行时态.找到主,谓 ,宾即可.

Answer 2

Good done!The work is being done.单独的done通常是省略形式的感叹语，而后者加Be动词是被动进行时的表达方式。

Answer 3

being
done表示正在发生的被动动作，所以在正在发生且被动的情况下使用
