Learning English at college is different from learning English at middle school. In middle school, we learn English mainly for the entrance examination for college, while the purpose of learning English at college is quite different. We study foreign languages now to improve our ability to work in the future and especially to communicate with foreiguers.
How can we learn English well at college? Firstly, you should try your best to enlarge your vocabulary. Only in this way can you read more smoothly and understand others well. Secondly, you should pay more attention to the listening and speaking ability in learning English. While talking with foreigners, if you can't understand them, and do not know how to express yourself, the talking will be very difficult. And the last point is that you should improve your English whenever and wherever you can.
Obviously, there is still a long way for us to go to learn English well. As a proverb says,
Never too old to learn.' There are so many methods to learn English. So long as you keep on studying, your English will surely be improved.
