问题补充:
In the past five years some new buildings in our home town.
A. build
B. was built
C. have built
D. have been built
答案:
A. build
B. was built
C. have built
(答案→)D. have been built
解析:D in the past five years“在过去的五年里”用现在完成时,类似的说法还有over the past few years等,“在过去的五年里,我们家乡已经建成了一些新大楼。”这里要用完成时的被动形式,即have been done。故选D。
