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 you ng people with others. But blo gs can become dangerous when they are read on the Internet by millions of people all over the world.

Recent studie s show that young people often provide their names, ages and where they live on the Internet. That may not be safe for them. This personal information puts them at risk 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 web site only if they know a secret word chosen by the blogger.

46. “Facebook” and “MySpace” are .

A. school subjects B. computer programs

C. school online BBS D. blog sites for young people

47. Blogs may be dangerous because .

A. surfing the Internet is bad for eyes

B. they are not allowed for school students

C. they get in the way of studies

D. personal information can be found in blogs easily

48. This passage is mainly about .

A. the safety of children’s blogs B. how to search the Internet

C. students’ behavior at school D. communicating with parents at home

49. According to the passage, many schools help children avoid(避免) blog problems by doing everything EXCEPT .

A. teaching parents about the web sites

B. asking students to use programs to refuse strangers

C. telling school students not to make any net friends

D. stopping students from blogging on school computers

50. You can enjoy your blog safely if .

A. you write your blog at school

B. you use a secret number for friends to enter your blog

C. your parents have little knowledge about web sites

D. you show all your writings and feelings in your blog
