Yesterday, we had an interesting English class. There were a group of American college students visiting to our school. Therefore, they acted as ourbeats by dre saleEnglish teachers yesterday, and the teacher of my class was Roan. He is twenty-two years old and he comes from Los Angeles. He has learned Chinese for more than 3 years, so sometimes we could communicate in Chinese. He simply introduced the United States to us, including geography, history and education. He shared us with his education experiences and told his stories to us, especially in the junior school. He was so active and energetic in the class and we were impressed. In the end of the class, he suggested us to be more active in the class and encouraged us to study hard. He said that he felt difficult to learn Chinese but he always tried his best.
