背诵为王第四册第15课 Exercise for Ever

Lesson15 Exercise for Ever!
In our pursuit of good health and shapeliness, most of us think immediately of dieting. If only we could eat less, we think, we'd soon be slim, happy and life would be problem-free.
It's true that dieting is one answer, though it can be the most agonizing and psychologically destructive, so why not think about it another way. Maybe it's not that we eat too much, but that we exercise too little. Most of us lead terribly sedentary lives; when we're not sitting at our office desks, we're sitting on a bus or a train or in a car or in front of the telly, and we very rarely go for a good brisk walk, let alone exert ourselves more vigorously.
Taking regular exercise can mean that you can eat decent, satisfying amounts, while not endangering your figure at all. Exercise, or better still sport - since sport is challenging, exciting and socially enjoyable too - can change your whole attitude to life. It can change a depressive, lethargic person into a happy, active one. It can change a flabby, clumsy person into a firm, perfectly controlled, and graceful one.
Exercise, so the doctors tell us, is a necessary antidote to stress, and it will help to keep your heart and lungs working well too.

锻炼身体不停息！
为了拥有健康身体和苗条身材，我们大多数人都会马上想到节食。我们认为，只要能吃得少一点，很快就能变得苗条、快乐，生活中的问题就会烟消云散。
节食确实是一个方法，但是节食会非常痛苦，会给心理带来损害。那么，为什么不考虑一下另外一种方法呢？可能并不是我们吃得太多，而是我们锻炼的太少了。我们大多数人生活中惯于久坐，很少活动，没有坐在办公桌旁的时候，我们总是坐在公共汽车上、火车上、汽车里或者电视机前，我们很少出去轻快地散步，更不用说运动量再大一点的锻炼方式了。
经常锻炼身体，你就可以吃好吃饱，还不会危及你的身材。锻炼身体，或者更好一点，参加体育运动&&因为体育运动富有挑战性、能振奋人心、能给人带来交际的快乐&&能够完全改变你的生活态度。它能使一个情绪低落、无精打采的人变得快乐并精力充沛。能使一个肌肉松垮、行动笨拙的人变得肌肉结实、生活规律、举止优雅。医生告诉我们，锻炼身体既是减轻压力的必要手段，也能帮助使我们的心肺处于良好的工作状态。
