的有关信息介绍如下:(1)Watching TV and listening to the radio are very important to me. There are various reasons for this. First, there is a lot of information available on TV and over the radio I benefit a lot from watching TV programmes with up-to-date news about China and other countries. Second, music is also part of my life. As a high school student, I am very busy with my studies and am under great pressure. Listening to radio programmes about music has become a routine which helps me relax and do better in my studies.
(2)Different electronic devices have changed a lot over time. Take mobile phones as an example. Mobile phones first appeared in 1947, and they looked much bigger than what we are using nowadays. In the past, they could only provide us with basic services like phone calls. However, customers now want to be entertained. As a result, many new types of phones are available, which can connect to the Internet or be used as cameras of MP3 players.
(3)These inventions have greatly improved people's lives. Mobile phones are a good example of this. Before mobile phones came into use, people couldn't make phone calls or receive phone calls if there was no telephone nearby. With mobile phones, people are able to make calls at any time and at any place. Today, many of us are very busy and cannot be expected to wait for a long time. Mobile phones provide us with a chance to keep in touch with others wherever we are.
