Years ago, if a teenager had some problems in his life, he might go home and write in his diary; now, ateenager with 1 problems might go onto the Intemet and write about them in a blog (博客). In many ways, a diary and a blog are very 2 . But what makes blogging different from writing in a(n) 3 diary? The biggest difference is that a blog is much more 4 than a diary. Usually, a teenager treats his diary like a book full of 5 that he does not want to 6 with others. It's interesting that someone who writes in a blog 7 a diary will probably write'nearly the same information. I have a little sister, and sometimes I go online to read her 8 . She writes about things like waking up early for swimming practice and not studying enough for her chemistry test. 9 I was her age, I wrote about the same thing, but 10 in my dairy. Then, after I had finished writing, I would hide my diary in a secret place because I was 11 that my sister might read it. The biggest 12 with blogging is that anyone can read what you write. If I was angry with a friend during high school and wrote something 13 about him in my diary,he would never know. 14 , if my sister ever wrote something bad about a friend,that friend might 15 her blog and get angry. There are also 16 to blogging,of course. If I was feeling sad one day and wrote in my diary, " Nobody cares about me…" Because no one would 17 about it. However, if my sister wrote the same sentence in her blog, her best friend would quickly 18 and tell her how much they 19 her. Blog help people 20 in contact with their friends and know what the people around them are doing.
