Last summer,I invited to a summer camp in America.I had great time there because I made many friends from other than countries.There were many different kinds of activities.In a party,we take turns to talk about our own country.But I was so shy to speak before other people.I stood there for five minutes without said anything.It was very embarrassed.When I finally opened my mouth,someone couldn't help laugh at my poor spoken English.I could feel almost anything except that my face was burning.It was then I decided to speaking English.
