As every body knows, mobiles are playing a important part in our daily life nowadays.But they have bot advantages and disadvtanges in my opinion.
First, mobiles make it convinent for people to keep in touch with each other whevere they are.Especially when they have something important.It reduces the cost for people dont have to travel a long way to get to know the things in person
Second,we can send messages by mobiles with little money,just 0.01 yuan for each short message.
third, we can also play games or take photoes or listen to music on the mobiles,late we do many things on them with the development of technology.
But they also have many disadvatages.we have to pay for the wrong numbers which are not for us.The radioactivites may do harm to our health.Sometimes the rings may affect others in public or at meetings
参考范文
每个人都知道，手机是我们每天生活中重要的部分，但在我看来它有利有弊。
首先，手机使人们互相保持联系方便。尤其是当他们有重要的事情。它降低了成本的人也要走很远的路去的人知道的东西。
其次，我们可以用手机发短信只需要很好的钱，仅0.01元可发一条短信。
再次，我们也可以用手机玩游戏，拍照片或者听音乐，随着技术的开发，以后我们还可以在手机上做很多事。
但是它也有很多缺点，我们可以错语的付费为某个号码，手机辐射可能危害我们的健康，有时铃声可能在公共场所或会议上影响他人。
