问题补充：

It’s dangerous to get close to the building now .

A. being constructed

B. constructed

C. been constructed

D. to be constructed

答案：

(答案→)A. being constructed

B. constructed

C. been constructed

D. to be constructed

解析：考查非谓语动词用法。本题考查现在分词短语做定语用法。关键词是now，表示现在正在进行的动作，所以使用现在分词，building与construct构成被动关系，使用现在分词的被动形式being done。句意：靠近正在被建的大楼是很危险的。故A正确。
