请根据下面所给的题目用英语写出一篇不少于80词的短文。 My Opinion on Cell Phones

We can see around us that more and more students are going to own a mobile phone .From NOKIA to SIEMENS, from national to imported, from low price to high price……
As a communication device, the mobile phone benefits us a lot. We can use it to keep in touch with our families, our friends and our classmates wherever we are. In festivals, we can send short messages to wish good luck to other people we known. It brings us a lot of convenience.
As a coin has two sides, the mobile phone also has disadvantages. We spend too much time on spelling our words and sending short messages that we can't focus on our studies. Also, you will always be annoyed by strangers' calls one after another.
In my opinion, we can use it. But we shouldn't spend too much time on it and don't let it disturb us from our studies. And we should not easily tell people our phone numbers who we don't recognize.
