单选题 If the building project ______ by the end of this month is delayed, the construction company will be fined.

A、 to be completed
B、 is completed
C、 being completed
D、 completed

【正确答案】 A

【答案解析】本题考查不定式做定语。分析句子结构可知，if条件句中已经有了谓语is delayed，故首先排除B；所填部分在句中应该是做定语，修饰the building project，由时间状语by the end of this month可知，此处是表示“即将被完成的”，故应该用不定式做定语。故答案为A。
