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.
