The number of the college students who(have )mobile phones has been greatly increasing since 2001
为什么用have不用单数呢?不是The number of 谁能讲清谁就讲,简单的翻译就别写上了,

这里就要弄清楚句子的成分与结构了,第一个have是做定语从句来修饰students的,是指拥有手机的学生,所以当然用的是复数了,第二个has才是你想的那样子修饰the number的呢,是指（学生）数一直在增长的意思么.

the college students who have mobile phones
the number has been

a number of 后面跟可数名词的复数形式，所以这里一定不能加S。

The number of the college students 能用单数吗?

你好你应该是高中生吧 the NO.of 句子后面是应该用单数的因为是NO.作主语只是表示一个数的量（具体语法上叫什么我忘了）但是看看句子后面是带的who从句从句主语是students 用have就没疑问了吧？！
