问题补充：

There are eight students in our school. They must be every day.

A. hundreds, on time

B. hundreds of , in time

C. hundred, on time

D. hundreds of , on time

答案：

A. hundreds, on time

B. hundreds of , in time

(答案→)C. hundred, on time

D. hundreds of , on time

解析：句意：在我们学校有800名学生，他们必须每天按时到校。当hundred前有数词时，hundred用单数；并且后面不能用介词of；故排除ABD；in time及时；on time按时。根据句意故选C。
