the teachers is about 300 in our school and it is becoming.

A. The number of, more and more

B. The number of, bigger and bigger

C. A number of, more and more

D. A number of, bigger and bigger

答案：

A. The number of, more and more

(答案→)B. The number of, bigger and bigger

C. A number of, more and more

D. A number of, bigger and bigger

解析：句意:我们学校老师的数量是大约300个，而且这个数量变得越来越大了。the number of …的数量；a number of 很多；根据句意可排除C、D两项。英语中修饰number 数量应该用big或small，即大或小，而不是many 或few。故选B。
