I read yesterday (yes, on a blog) that there are now blogging competitions! I can't believe it. A man in England
won $2,000 for writing the best blog. There's even a list of the best Chinese bloggers! I've read a few of them
— before they were famous, I might add. I suppose that one blog can be better than another. It can be better
written, more interesting, funnier, and I suppose that blogs are there to be read and judged (点评) by other
people. If they're not good, they're not read. And they're not just personal feelings. If they were, they'd be called
diaries. Have locks, and be hidden under beds. So I'm OK with this whole competition thing. I just can't believe
I didn't win!
This has got me thinking about why I'm writing this blog. I'm not doing it to win a competition (or I wasn't
when I started...) and I'm not doing it to show all my personal feelings - I do that in my diary. So, why am I a
blogger?
To tell the truth, the first time I heard the word blog I thought it was a new word for a toilet. But I love
learning new words so I used my knowledge and found out that a blog was a personal website and the word
blog came from the words web log. Now a log is a type of diary kept by sailors, and web, well, we all know that
it has nothing to do with catching flies and everything to do with the Internet. Web log… weblog… blog. Being
a writer I loved the idea of getting my views onto the Internet where anyone could read them, and no editors
(编辑) could get their hands on them!
So my first reason for blogging: I'm a writer. I want people to read what I write (un - edited!). And I love
writing about anything I choose. I can write about saving the environment or complain about how the people in
front of me in the cinema always seem to have big heads. And sometimes I pour out my heart too.
My second reason is that it's relaxing. I don't have to do research and write an article. I can let my thoughts
go on as long as I like.
Third reason? To keep in touch. I'm terrible on the phone and all my friends around the world read my blog
(or they say they do...). Every now and then, I even upload a photo so they remember what I look like.
Is there a fourth reason? There probably is but now it's time for dinner. Tomorrow I might even tell you what
I ate.
A. his writing about feeling can be shown anywhere
B. his writing would never be edited by others
C. he enjoys writing something about big events
