     It's over three years since I began to learn English. I am glad that I am getting on well with it.

     I find English quite difficult, but very interesting. When I first started, I thought I had only to remember

the new words and learn some grammars. I know little about English idioms (习语). I thought each English

word has the same meaning in Chinese. When I learned to say "I see a book on the desk", I thought the

English word "see" was just like the Chinese word "kan". So one day when my teacher asked me, "What are

you doing?" I answered, "I'm seeing a book." "That's wrong." The teacher said. "You don't see a book. You

read a book. You can't use an English word like a Chinese one. Be sure not to make the same mistake again."

     After that I began to pay more attention to the differences between Chinese and English. For example, in

English we say a "high mountain", but a "tall man". In Chinese we use the same word "gao" for both. Again

in English we say "take part in the sports meeting", "attend a meeting" and "join the army", while in Chinese

we can use "can jia" for all three. Interesting, isn't it?

     So to study English doesn't only mean hard work, it can be great fun, too! We not only have to pay

attention to pronunciation, grammar, spelling and handwriting, we also have to understand English idiom. We

can learn English well only in that way!

     But all this is only a beginning and I still have a long way to go. I'll try my best and work even harder than

before. I must speak and listen to English more both in and out of class. I must learn English well so that I

work well when I grow up.
