Teens and Inventions
Nowadays, there are many useful and cool inventions around us. Among these inventions, the intelligent mobile phone is my favorite.
As a student, the intelligent mobile phone helps me a lot. With it, I can find lots of information I need. I can read books, know the latest news and watch movies. I can play games or listen to music when I am tired. It makes it easier for me to communicate with my friends. I often chat with them through e-mails and QQ. We cannot rely too much on our phones, and at the same time, we also need to take timely breaks. Though a lot of people find some bad effects the intelligent mobile phone has on us, I think as long as we use it properly, the intelligent mobile phone must be beneficial to us.
