Learning English at a college is different from learning English at a middle school. In a middle school, we learn English mainly for entrance examination for college, while the purpose of learning English at a college is quite different. We study foreign languages now to improve our ability to work well in the future and especially to commnicate with foreigners.
Having been studying here for nearly 2 years, I have come to some conclusions about how to learn Enlgish well. Firstly, you should try your best to enlarge your vocabulary, only in this way can you read more and understand others ms well. Secondly, listening and speaking play important roles in learning English. While talking with foreigners, if you can't understand them, how can you express your ideas? And the last point is that you should improve your English level whenever you can.
However, there is still a long way to go to learn English well. As people usually say, "There is no end to learning". There are .so many methods to learn English. So long as you keep studying, you will surely improve.
