Question

Every year, there______ a number of students taking after-class lessons. The number _______ larger than before.
A. are; is         B is; are          C is; is           D are: are

Answer 1

A

试题分析：句意：每年有许多学生参加课外活动。人数比以前都多。前空是there be句型，主语为a number of students，a number of 许多，修饰中心词students，故系动词用are。第二空是the number作主语，系动词用is。故选A。
