Happy dragon boat festival! (As a matter of style, it would probably be best to capitalize the first letter of each word for two reasons 1. name of festival  2. title of your article)

Today is Dragon Boat Festival, which is a traditional festival in China. On this very special day, I'm joining  italki, and starting my new journey (or "trip" -- not "travel," which is only used as a verb) on learning English. To be honest, I did poorly in English in my senior high school (correct, although the phrasing is a bit unusual), not only the grammer, but also (the) speaking. I really hope that I can find a good friend who use with English as his / her mother language. I`m Iris, write me soon, please.

Great job, welcome to italki. I wish you good luck! Btw, is "Iris" like the colored part of the eye, or is it a reference to the goddess of the rainbow?
