Being a product of high-technology,mobile phones are being more and more widely used. It's small in size, light in weight and easy to carry, offering fast and convenient service for communication.It's of multi-function. The users use it for calling, sending short messages and internet-surfing.

In recent years, mobile phones have become popular among middle school students. Quite a few use them at school to keep in touch with their families and friends instead of writing letters, which, of course brings convenience to them. But I don't think it's good to do so.

In spite of the advantage mentioned above, student users often waste a lot of time chatting over the phone in their spare time, some even use them to cheat in exams. In addition, mobile phone bill is also a heavy burden on students' families.

作为一个高科技产品，手机正被越来越广泛的应用。它体积小，重量轻、易携带，为通信提供快捷方便的服务。它有很多功能。用户使用它的电话，发送短信息和互联网冲浪。

近年来，移动电话已成为很受中学生欢迎。相当一部分学生用手机保持联系与他们的家人和朋友而不是写信，这给他们带来了很大的方便，当然。但我不认为这样做是好的。

尽管上述的优势，学生用户往往浪费大量的时间在他们的业余时间打电话聊天，有的甚至使用他们在考试中作弊。此外，手机账单也对学生家庭造成沉重负担。
