【简答题】
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. 小题1:“Facebook”and“MySpace”are .
