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。
