手机优缺点

Like everything else, mobile phones have both favorable and unfavorable aspects. First, it's useful. As a wireless mobile telephone, it's easy and handy to call wherever one goes and call the one however far away he is. Second, it's convenient. Whenever one meets trouble or something urgent, one can make a call immediately. However, the mobile phone also has many disadvantages. First, it's expensive to buy and costly to pay the bills. Second, it's also easy to lose and costly to get it repaired. Third, it's alleged the microwaves in it might do harm to people's health. I believe its advantages will far outweigh disadvantages soon.
