Show Ourselves, Improve Ourselves
In order to make us enthusiastic about learning English and develop our knowledge, our school organized some colorful English activities last week. During the week, we learned English songs and went to English Corner, where students communicated with each other about the subjects they were interested in. Besides, we attended an English lecture delivered by a foreign expert. Everyone thought it was a good chance to improve our listening and widen our horizon. On Friday, an English composition contest was held to encourage us to show our talents for writing. Most of students were highly interested in those activities, which boosted our confidence in learning English to a great degree.
I’m glad to receive your letter. But at the same time, I’m sorry to hear that you are not very well these days. In your letter you asked me how to stay healthy. Here is my advice.
Firstly, you should keep a balanced diet. You should avoid eating food high in fat and too much sweet food. You’d better eat more fresh vegetables and fruits. Secondly, taking exercise every day helps build (up) a strong body. Why not take more exercise in your spare time? As we all know, regular exercise is an important part of keeping us healthy. Finally, make sure you have enough sleep and you mustn’t stay up too late at night.
By eating properly and exercising regularly, you can keep your body at a proper weight and stay healthy. I truly hope my advice is helpful and you’ll get well soon.
