Years ago, if a teenager had some problems in his life, he might go home and write in his diary; now, a teenager with 26 problems might go onto the Internet and write about them in a blog（博客）．In many ways, a diary and a blog are very 27 ．But what makes blogging different from writing in a（n） 28 diary? The biggest difference is that a blog is much more 29 than a diary. Usually, a teenager treats his diary like a book full of 30 that he does not want to 31 with others. It’s interesting that someone who writes in a blog 32 a diary will probably write nearly the same information. I have a little sister, and sometimes I go online to read her 33 . She writes about things like waking up early for swimming practice and not studying enough for her chemistry test. 34 I was her age, I wrote about the same things, but 35 in my dairy. Then, after I had finished writing, I would hide my diary in a secret place because I was 36 that my sister might read it. The biggest 37 with blogging is that anyone can read what you write. If I was angry with a friend during high school and wrote something 38 about him in my diary, he would never know. 39 , if my sister ever wrote something bad about a friend, that friend might 40 her blog and get angry. There are also 41 to blogging, of course. If I was feeling sad one day and wrote in my diary, “ Nobody cares about me”, because no one would 42 about it. However, if my sister wrote the same sentence in her blog, her best friends would quickly 43 and tell her how much they 44 her. Blogs help people 45 in contact with their friends and know what the people around them are doing.
