书面表达。
近来，越来越多的同学拥有手机。一部分同学认为手机可以用来联系家长和同学，还可以听音乐、
照相；又有一部分同学认为每天跟家长、同学在一起，没有必要用手机联系，手机对我们的学习有影响。
就学生买手机问题，谈谈自己的看法和建议。
One possible version:
Recently, more and more students have mobile phones.
Some students think that it is convenient to use them to keep in touch with parents and classmates. Also,
they can be used to listen to music or take photos.
But others thinks that we don't need to talk with parents and classmates withmobile phones, because we
meet them every day. And mobile phones may influence our study.
I think its OK for us students to have mobile phones, but we should use them in the proper way.
