【答案】Dear John，
I'm glad you are interested in physical exercise.In view of the 2022 Winter Olympics held in Beijing，the craze for winter sports is on the rise.I'm writing to recommend skating to you in your spare time.
To begin with，skating can help build up your body.It can also remove stress and tension and keep you relaxed，which contributes to your physical and mental health.Besides，your sense of balance and flexibility will get improved.You'd better choose a professional coach and a safe stadium.Take care of yourself while exercising.After all，safety always comes first.I hope you can enjoy it.
