His spoken English ___ in the past few years.
A was improved B has improved C has been improved D improved 选什么,为什么?improve什么情况下用被动,什么情况主动表被动?谢
答
yes,C is right
答
选C。
口语肯定是被说口语的人提高，所以是被动。过去的几年是个时间段，所以用过去完成时。
主动被动之分，举个例子吧：
The problem has been improved. 问题被改善了，属被动。
I have improved this problem. 我改善了这个问题，人为的属主动。

答
C
答
C
首先是被动,所以be improved
然后在过去的几年中,表示现在完成时
用 has
结合起来就选择C
