Why I use this blog April 26, 2008

I am applying for a Ph.D position in biological science. I have sent over 150 letters of application, however I got only reject replies:(. Maybe my letters are not chamming, or my English is suck. So I decide to improve my English and make friends in WordPress.com. I hope you guys give me some suggesions for my words and sentences. Certainly, we are friends, we could disscuss all we are both interested here.
