Cell phones do play an important role in people’s daily life, but every coin has its two sides.

To start with, as a wireless mobile phone, it’s convenient for the user at any time to contact others. Secondly, it’s a helpful companion. With a multifunctional

cell phone in hand, one can easily surf the net, downloading what he needs. However, the cell phone also has many disadvantages. For one thing, the machine

itself is very expensive and its local service is very costly, not to mention its global service. For another, the radiation from the mobile phones might do harm to the user’s health. In my opinion, with its expenses being reduced sharply after China’s entry into the WTO, its development will have a brighter future. Therefore its advantages will far outweigh its disadvantages.

My view is based on such reasons. They are the first people we meet. They teach us how to eat, and then how to walk. They teach us to speak, and they give us communication skills and so many others. They try their best to teach us, and develop our own learning skills. On the other hands, their words and actions will deeply affect our minds and decisions. Leading by example is an important way our parents teach us social skills, morals and how to get along with others. I believe that most of us have seen a public-interest advertisement on CCTV. The scene is about below: a young mother comes back home, after busy working for a whole day, she feels very tired. But she still washes feet carefully for her mother. All these have been seen by her little son behind the door. After his mother finish, the little child carries a basin of water slowly for his mother, and said “Mum please wash your feet.” All these tell us that the parents’ good actions will give a good example for their children. In our life, we follo w many people to study. Because every person we meet has something that we can learn. However, the greatest teachers in our lives will be our parents, because they were our first and most important teachers.
