Dying to Be Thin
Dear Zhou Ling,
How are you I haven"t heard from you for weeks. Is everything okay with you
Do you still go to the gym every day I used to go to the gym three times a week, but I don"t work out any more. I know another way to stay slim. Looking good is important to woman, isn"t it Every woman wants a slim figure these days, especially here in Canada. I"m trying to lose weight because I"m so ashamed of my body, since I"m preparing to act in a new TV play. I"m taking weight-loss pill called Fat-less, which are quite popular among young woman here. I hope to lose at least 10kg. I take two pills a day and don"t need to exercise.
The pills really work! I"m becoming slimmer and slimmer. I"ve lost 7kg in the last two months. However, sometimes I feel tired and weak. My mother, whom you met last year, keeps telling me not to take them because they are dangerous. She says health is priceless, and I agree, but then I look so slim at the moment.
Write soon!

Yours,
Amy

Dear Zhou Ling,
Things change so quickly! I"m now in hospital recovering from liver failure. I regret taking those weight-loss pills. They contain a harmful chemical that caused my liver to fail. The doctor told me that I would die if I couldn"t get a new liver. My mother is too old for such a long operation.
I thought I was going to die.
Then the doctor found that someone in your country, whose name is Li Dong, was an exact match for me. He donated more than half of his liver to save my life. I was very lucky, wasn"t I
I"m feeling better now. I follow my doctor"s advice and exercise for at least half an hour everyday (but I seldom go to the gym!), and eat lots of fruit and vegetables. People should look after their bodies. My mother is right: don"t damage your health for a slim and attractive figure. It isn"t worth it. We shouldn"t be ashamed of the way we look, should we
I hope to hear from you soon.

Love
Amy
