[范文]
this chart shows the rapid increase in the rate of students who have cell phones in a university between1999 and . in 1999, only 3 percent of the students had cell phones while in the rate rose to 18 percent. in , however, the rate soared to 56 percent.
several factors have attribute to this significant change. the most important is the development of the cell phone industry which has made the cell phone cheap, and the telecommunication industry which provides the users with a better service. many years ago, for eample, it took about several thousand, or even more than ten thousand yuan to buy a cett phone. now, however, a cett phone of ecellent quality costs onty about one thousand yuan. the net important reason is that many students now hold a part time job, which enables them to have more pocket money. they can spend this money on anything they like.
although cett phones bring college students a tot of benefits, they have atso caused some problems. some students, for instance, do not turn their cett phones off during classes, as a result, they often interrupt their teachers and classmates during lectures. other students sometimes use their cett phones for other purposes. they send meaningless or even pornographic messages to make fun. so i would tike to suggest here that students should make better use of their cell phones.screen.width-333)this.width=screen.width-333>
