I often hear some students say English is difficult, and it gives them a headache. So they can’t learn it well. But English is very easy for me. I’m good at it. I’m very glad to tell you something about how I study English.

First, I think an interest in English is very important. When I was in Grade One, we had a new subject -English. It was fresh for me. I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!

Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary. Then practice again and again, never be tired. And I also have a good habit: Asking whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand!

Besides this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.

And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.

Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.
