某校周刊在中学生中展开了就中学生能否在校园使用手机的大讨论。请你根据以下提示，发表自己的看法.
    1．手机是高科技的产物，它不仅体积小，重量轻，携带方便，而且通信快捷。它的功能齐全，既能用于通话，又能传递短信息和上网等。
    2．有不少中学生把手机带进学校，与家长和朋友保持联系，取代书信交流；有的学生甚至在考试中用手机传递答案，作考试作弊之用。
                     Mobile Phone
     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.
