不唯一 Dear Sarah, I’m sorry to hear that you’re getting fatter. I suggest you go to the doctor for advice. Meanwhile, please do not eat too much ice cream, chocolate or hamburgers, because they contain a lot of fat. You’d better eat more fruit and vegetables and exercise more. If you keep on doing so, you’ll lose weight soon. Several days later, you’ll become a slim and pretty girl. With best wishes. Yours truly, Jane
