Prices _______ sharply in the past few years.

问题描述:

Prices _______ sharply in the past few years.
A have raised B have been raised C have been risen D have risen
为什么?

B have been raised
Prices have been raised sharply in the past few years.
翻译;价钱在过去的几年张了许多
a和d排除,因为必须要have been.因为是过去几年所以要过去式raised,所以是b
抱歉,刚才跟团队商量了一下是d.我是错的.
