First notebook entry: Introducing myself

I am a pretty girl. I liveing in guanghzong now. I am a volunteer .I want to improve my English than I could help so many people!

------------------------------

- "I am" is okay, it is also okay to use "I'm" which also means I am, but it is shorter.
- Since you put "now" after where you live, it must mean you have moved?  So we should edit that a bit..
- You could say "I've recently moved in.." But we could write it differently if that's not what you meant.
- It is best to put topics together than say it randomly and out of place, so I put some of your sentences elsewhere/somewhere else (some are together/fused) and now it's easier to read and it makes sense.  It's just like a essay with the paragraph bodies.
- One important thing about typing is that after periods ( . ), you should double space after to start off your new sentence.  It was only one error that you had with that and it was at the part after "I am a volunteer  .I..." I think you accidentally switched it around.

Here is an edit I did of your introduction:

I'm a pretty girl who's just started living in guangzhou.  I want to improve my English so that I could be able to volunteer and help others with English!
