I am bace 7 months ago i register my ID on italki.com with a wish that i can talk with english speaker. i'v been asked for learning english since i was a primary student, i'm 25 now, you see, a decade for learning a lunguage. but actually i think my level is no better than a 10 years old english speaker. it's much diffrent now, no one push me to learn english any more as a sbuject which is at least in my country. now it's me who want to speak english from my own wish, a wish that a curiosity to diffrent culture, to broaden my horizon, or simply for english shows, movies, books. I'm not a clumsy learner, it's the motivation and the wrong way result in my low level english after a long studying. lunguage is just a tool for me, if we both get what we express each other, that's will be ok. further that, if i can speak more fluent or have a native accent by a period of time communication, that will be marvelous for me. As the begining, this ID has been exist 7 months, and i'm not on line for 6 months. even back then, i find so many chinese speakers're seeking for english partners, you know, it's not easy to establish a steady partnership, at the first month even only few couple guys want to chat with me, you know, just few simple words. i almost give up on italk. but i'm back now. Well, what i want to say is, i am seeking for native english speakers sincerely. and i must declare firstly that i can just speak mandarin, but i'm well educated, i believe that i can help you to improve your level if you want to acquire mandarin. i expect for a 50/50 exchange, any topic, any chat is ok, skype or not is ok, i can compromise with your local time as much as possible, just hope for developing into a steady partnership, even a friendship. not only for lunguage ablity but also for two diffrent world experience exchange.

The Penguins I'm so happy this week ,I'm addicted to an animation series called "The Penguins of Madagascar". Those fat and funny penguins are just like the mafia of the zoo.They are kind but always help other animals by a violent way.I can't enjoy it without the captions ,the penguins speak so fast and they use so many slangs,there are many words I don't know.I wish I can say goodbye to the captions one day.
