Years ago, if a teenager had some problems in his life, he might go home and write in his diary; now, a teenager with the    36   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   37  , but what makes blogging different from writing in a(n) 38  diary?
The biggest difference is that a blog is much more   39  than a diary. Usually, a teenager treats his diary like a book full of   40  that he does not want to   41  with others.
It’s interesting that someone who writes in a blog   42 a diary will probably write nearly the same information.
I have a little sister, and sometimes I go online to read her 43 . She writes about things like waking up early for swimming practice and not studying enough for her chemistry test.
44 I was her age, I wrote about the same thing, but   45  in my diary. Then, after I had finished writing, I would hide my diary in a secret place because I was   46 that my sister might read it.
The biggest   47  with blogging is that anyone can read what you write. If I was angry with a friend during high school and wrote something 48  about him in my diary, he would never know.   49 , if my sister ever wrote something bad about a friend, that friend might
50  her blog and get angry.
There are also   51  to blogging, of course. If I was feeling sad one day and wrote in my diary “ Nobody cares about me …”, no one would   52  about it. However, if my sister wrote the same sentence in her blog, her best friend would quickly   53  and tell her how much they   54  her. Blog helps people   55  in contact with their friends and know what the people around them are doing.
