It is over 3 year now since I began study English. At first I found it very difficult. I couldn’t get most of the sounds right, spell the words correctly and remember the rules of the grammar. Under the help of my English teacher and classmates, I have made many progress. Now I am getting well with my English study. Three years’ study have taught me that one can’t learn English well without working hard. We should do more listening and speaking both in and out of the class. At the same time, we must pay enough attention to read as well as writing. Only on this way can we get the best result in the shortest time.
