We are learning English, but how can we learn English well? A student can know a lot about English, but maybe he can not speak English.
If you want to know how to swim, you must get into the river. And if you want to be a piano player, you must play the piano. So, you see, you can learn English only by using it. You listen to your teacher in class . You must read your lessons every day. You must speak English to your classmates and also you must write in English. Then one day, you may find your English very good.
