Since we went to school, we have access to English all the time, because it is one of the necessary subjects. Before we attend college, we keep our attention on the grammar, but now college means the new stage and we should pay attention to practical English. Here are some suggestions.
First, it is important to speak out loudly. The purpose of learning English is to communicate with foreigners, so as to get to know more about the world. Grammar is not the only thing we care about. What we should do is to open our mouths and improve our ability to use spoken English. It begins with reading textbooks. When we listen to the tapes and repeat many times, then our accent can be corrected.
Second, just talk to someone in English, such as your classmates or your friends. Though both of you will surely make many mistakes, if you insist, then in the long run, you will gain a lot. You start to have the courage to speak English. If there is an English corner, just join and take without hesitation. You will make great progress.
