问题补充：

The boss often the workers for 12 hours a day.

A. make, work

B. makes , to work

C. makes , work

D. make , working

答案：

A. make, work

B. makes , to work

(答案→)C. makes , work

D. make , working

解析：C 考查使役动词make和主谓一致。The boss是单数，故用单数makes，“让某人做某事”make sb. do sth.，被动语态时要把to带上，即sb. be made to do sth.。
