问题补充:
The tall building in the center of this area will be used as a 5-star hotel.
A. to built
B. building
C. being built
D. having built
答案:
A. to built
B. building
(答案→)C. being built
D. having built
解析:句意:在这个中心正在被建的高楼将被用作5星级的旅馆。will be used是谓语动词,整个句子没有连词,所以空格处应该是非谓语动词,The tall building与build之间是被动关系,故排除ABD;根据句意故选C。
