A mobile phone is getting increasingly popular.(主题句) Statistics show that eight out of ten college students have got one.(数据支撑) However, as is the case with many issues, a mobile phone has both positive and negative aspects. (承上启下)

On the positive side, a mobile phone allows calls to be made instantly from almost any location. This can be vital where emergency services need to be called to the scene of a crime, accident or fire, where no public telephone is nearby. (优点1) Meanwhile, a mobile phone can serve as a connection to the Internet, which can be extremely convenient for obtaining information wherever you may be. (优点2)

The fact that a mobile phone allows a person to be contacted at any time can in itself be a disadvantage. For instance, an employee may, via the mobile phone, be constantly available to his employer and feels that he never leaves work. This may cause distress. (缺点1) Another disadvantage is the perceived health risks associated with its use. Some people believe that using mobile phones for long periods can damage the brain. (缺点2)

There is no denying that a mobile phone has both benefits and drawbacks but on balance perhaps the advantages of a mobile phone outweigh its disadvantages since a mobile has become an integral part of modern life. (结论)
