Millions of young people are writing blogs. Millions of others are reading them. The word“blog”is a short way of saying Web log.

 Many popular Web sites now offer free，easy ways to create personal Web pages and fill them with writings and pictures. Web sites called “ Facebook ” and “MySpace” are some of the most popular blog sites for young people. Many young adults use their blogs to write about daily activities and events in their lives. They also provide a place for people to write their ideas and opinions and how they think of others’ ideas.

 Blogs offer young people a place to show their writings and feelings. They can also be helpful to connect young people with others. But blogs can become dangerous when they are read on the Internet by millions of people all over the world.

 Recent studies show that young people often provide their names, age and where they live on the Internet. That may not be safe for them. This personal information puts them at risk(风险)of being searched out by dangerous people who want to hurt them. Many students do not know about privacy(隐私)and are surprised to learn that adults can read their personal daily records easily. Students can also get into trouble when they put information about others on their blogs.

As a result, many schools have banned (禁止) the use of blogging Web sites on school computers. Many schools have also begun teaching parents about the Web sites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out private information. One way to keep away from these problems is to use programs so that blogs can be read by “friends only”. People can read the website only if they know a secret word chosen by the blogger.

Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
