选择题
---- How is your hometown after the earthquake for 2 years.
-----Thanks to the government, the reconstruction work of schools and farm houses ________ and people are living a happy life.
A．have been completed
B．has completed
C．was completed
D．has been completed
答案
答案：D
考查时态语态及主谓一致。句意：地震后两年你的家乡怎么样了？——多亏了政府，学校和民房的重建工作已经完成，人们过上了幸福的生活。结合语境可知下文描述的是现在已完成的动作，reconstruction work为动作对象，故用被动语态。抽象名词不可数，故谓语动词用单数，选D。
