问题补充：
We hope the building project will be completed as soon as possible because a lot of citizens are complaining about the noises.
A. to be carried out
B. carried out
C. being carried out
D. carrying out
答案：
A. to be carried out
B. carried out
(答案→)C. being carried out
D. carrying out
解析：本题易误选A、B。句子结构是：we hope后面是一个宾语从句。主句是the building project will be complete as soon as possible，再后面是一个原因状语从句。中间应该做定语来修饰the building project。carry out是完成、执行的意思。在本题中我们可以看到市民抱怨的是噪音的巨大，所以工程己经开始了，并且正在进行。同时carry out跟修饰语是动宾关系。
