问题补充：

A modern stadium in that new town, soon, will be an ideal place for people to have all kinds of sports in.

A. completed

B. to be completed

C. being completed

D. to have been completed

答案：

A. completed

(答案→)B. to be completed

C. being completed

D. to have been completed

解析：B 考察非谓语动词。分析句中结构可知stadium和complete构成动宾关系，所以应该使用动词的被动形式。根据语境可知，complete这一动作还未发生，空格表示将来，应该使用不定式to be completed符合语境。故B正确。
