Mobile Phone Being a product of high-technology,mobile phones are being more and more widely used. It's small in size, light in weight and easy to carry, offering fast and convenient service for communication.It's of multi-function. The users use it for calling, sending short messages and internet-surfing. In recent years, mobile phones have become popular among middle school students. Quite a few use them at school to keep in touch with their families and friends instead of writing letters, which, of course brings convenience to them. But I don't think it's good to do so. In spite of the advantage mentioned above, student users often waste a lot of time chatting over the phone in their spare time, some even use them to cheat in exams. In addition, mobile phone bill is also a heavy burden on students' families.Nowadays more and more families own private cars. Private cars, as the product of modem civilization, have been playing a vital role in people's daily activities. First, private cars are a convenient means of transportation. You can go wherever you like. Secondly, there is no doubt that private cars will have a great impact on the economic growth. The rapid car industry growth will contribute much to keeping the country's economy growing at a higher rate in the near futrue. But every coin has two sides. The development of the private cars will bring about a series of problems. For example, the polluted air given off by cars will do great harm to our health, too many private cars will lead to traffic jams and a great deal of energy will be wasted and so on. So I think we should take advantages of private cars and make them serve us better. Meantime we hope that satisfactory solutions to these negative problems will be found soon.
