问题补充：

—How many students are there in your school?

— students, I think.

A. Thousand of

B. Three thousands

C. Three thousand

D. Three thousands of

答案：

A. Thousand of

B. Three thousands

(答案→)C. Three thousand

D. Three thousands of

解析：句意：---你的学校有多少学生？ ---我想，有三千人吧。英语中，表示数量的名词前面有具体数字（one，two…）时，后面的hundred ,thousand ,million等必须是单数，而且不能加of。若前面无数字，hundred ,thousand ,million等必须是复数，而且加of，如thousands of people 成千的人，thousands of 数以千计的，其中的s不能省略。结合句意可知选C。

考点: 考查数量的表达的用法。
