解释如下
手机”的优点和缺点
众所周知，手机在当今的日常生活中扮演着重要的角色。但在我看来，它们有优点也有缺点。
首先，手机使人们无论在什么地方都保持联系很方便。尤其是当他们有重要的事情时。它降低了人们不必走很长的路去亲自了解事情的成本。
第二，我们可以用手机发送短信。
第三，我们还可以在手机上玩游戏、照相、听音乐，后来随着科技的发展，我们在手机上做了很多事情。但是他们也有很多缺点。我们不得不为错误的数字买单。这些放射性物质可能对我们的健康有害。有时这些手机铃声会在公共场合或会议上影响其他人。
我相信不久手机的优点就会远远超过其缺点的。
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.
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.
I believe its advantages will far outweigh disadvantages soon.
