It has been three years since I start learning English. At first I found its quite difficult. I couldn’t pronounce words well, spell correct and remember the rules of grammar. With the help of my teacher, I have made a great progress. Now I am getting well with my English. Three years’ study have taught me that one cannot learn English well with hard work. We must do more listening and speaking both in and out of class. We must also do more reading or writing as well. What is known to all, “Practice makes perfect.” That’s the most important thing. Besides, we should also practice use it as much as possible.
