问题补充：
If the project by the end of this month is delayed , the company is sure to pay a large sum of money for it .
A. completed
B. completing
C. to be completed
D. having completed
答案：
A. completed
B. completing
(答案→)C. to be completed
D. having completed
解析：
试题分析: 考查非谓动词语。A选项过去分词表示被动完成；B选项现在分词表示主动进行；C选项不定式的被动形式表示被动和将来；D选项现在分词的完成式表示主动完成；从结构判断 by the end of this month是非谓语做定语用来修饰project，而且从this month 可知此处表示将来，所以答案选C。句意：如果计划到月底竣工的项目被耽搁了的话，公司肯定得为此偿付一大笔钱。
