dear jenny,
how nice to hear from you! in your letter you asked me how to keep healthy. i
would like to give you some advice.as you know, we teenagers grow very fast, so we need plenty of nutritious foods,
such as fish, meat, eggs and beans, especially fresh vegetables and fruit. youd
better not eat too much sweet food. also, its necessary for you to take physical
exercise regularly instead of studying in the classroom all the time. for example,
you can play basketball or swim after school. whats more, having enough sleep is
very important. so i advise you to have at least eight hours of sleep every day and
not to stay up too late. only in this way can you keep energetic and have a healthy
body.
