英语中被字句的句型
3个回答

一种是一般被动语态 就是普通的be+done 比如 my homework is(was过去式)(has been现在完成时) finished

另一种是进行时态 比如The performance is being played now

还一种就是未来时态 比如 Maybe most human workers will be replaced by robot

最后就是吧完成时和这三种语态结合起来的被动形式 如have been done(现在完成时的被动语态) had been done(过去完成时的被动语态) will have been done(未来完成时的被动语态) 还有一些在深入的 以后碰到再问吧!
