题目内容
Listen, a small number of students ______ in the classroom.
| A．talk | B．talks | C．is talking | D．are talking |
D
解析试题分析：根据a small number of students“少量学生”作主语可知，其后的谓语动词应该用复数形式，故应该排除BC；又根据listen可知，本句的时态应该是现在进行时。所以本题选D。
考点：本题考查时态。
点评：本题有两个关键点：一是时态，要注意动作发生的时间，尽量找出句中表示时间的词或短语；二是注意区分a number of和the number of的区别：a number of是“许多的”，作主语时谓语动词要用复数；而the number of是“……的数量”，作主语时，谓语动词要用单数。
