Question

【题目】 Look! There _______ a number of students running on the playground. The number of them _________ 15.

A. is; is B. is; are

C. are; is D. are; are

Answer 1

【答案】C

【解析】

试题分析：句意：看，有许多学生在操场上跑步。有15个学生，第一空是考查there be句型，其主语是a number of students，是名词复数，所以用are；第二空主语是the number，所以应用is，因此此题选C。
