Thank you for replies,
10 months ago, my English is much worse than now, I had studied English for 8 years from middle school to college, when I came to Palau, I found I could not understand my workmates' English(They are Philipinos and ... people), and they also could not understand my English, It just looks like we were speaking quite different language, so I decide to go to church to study English in order to get rid of my Chinese style English, then my friend introduced me to the Jehovah's witness kingdom hall, they taught English every friday night, When I got to there to study English , I found they were very warmhearted. I was moved, b/c everyone were very kind to you, so gradually I like peopole in the kingdom hall as well as the environment, even I have a lot of questions, for example they never encourage people work hard, and they take the negative attitude with science, I had to work hard to sustain my dog life, if I only go to preach I would starve to death, I also consider my temporary life is very important; I think if there havent science invention, our life would become much worse than now, Probably we could not share these ideas at this forum.
