问题补充：
The manager discussed the plan that they would like to see the next year.
A. carry out
B. carrying out
C. carried out
D. to carry out
答案：
A. carry out
B. carrying out
(答案→)C. carried out
D. to carry out
解析：句意：经理讨论了那个他们想要看见明年实施的那个计划。carry out执行，实施。这里that引导的是定语从句，它在从句中作的是宾语，先行词是plan，这里是短语see sth done，sth与do之间是被动关系，see the plan carried out，the plan与carry out之间是被动关系。
