    Years ago, if a person has some problems in his life, he might go home and write in his diary. Now

he might go onto the Internet and write about them in a blog(博客).

Differences between a blog and a diary

     Usually, a person thinks of his diary as a book full of secrets. He does not want to share. But in the

blog, anyone can read what he writes.

     I have a little sister, and sometimes I go onto the Internet to read her blog. She writes about swimming practice and not studying enough for her chemistry exam. When I was her age, I wrote about the same

things, but only in my diary. Then, after I finished .writing, I would put my diary in a secret place because

I was worried that my sister might read it!

Problems with blogging

     The biggest problem with blogging is that anyone can read what you write. If I was angry with a friend

and wrote something bad about her in my diary, she would never know. However, if my sister wrote something bad about a friend, that friend might read her blog and get angry.

Because we do not always think about things carefully before we write about our days, it is easy to hurt

others' feeling in a biog. So we have to be very careful about what we write.

Keeping in touch with friends

     Blogging has both good and bad points, of course. People choose to blog because they know that

their friends will read what they write.

If I was feeling sad one day and wrote in my diary "Nobody cares about me," no one would know about

it. However, if my sister wrote the same sentence in her blog, her best friends would quickly reply and

tell her how much they like her. Blogs help people keep in touch with(保持联系)their friends and know

what the people around them are doing.

     Blogs are a very good way to write about daily life, if people are careful about what they write.

However, I still like writing better in my diary!
