You shouldn't take anything doesn't belong to you.（)

Once upon a time (not so very long ago, either!) industrial goods were made to last forever. If you bought a ear or a stove, it was a once-in-a-lifetime investment(投资). You paid good money for it, and you took care of it. Nowadays industry has persuaded us that products shouldn't last a long time. It's cheaper to throw them away than it is to repair them. This has led directly to the "throw-away society" which is a tremendous waste of the earth's resources.

Just think of the cars that are traded in daily, just because they are out of style. Think of the expensive packaging material that is thrown away every time a new object is bought. And we consumers have to pay for that material! Our industrial society has turned us into spoiled children. This wastefulness has got ten us into the mess (困境) we are in now. When we have no resources left, then we'll start to take care of what we have. But why can't we act before this happens？ Why can't we go back to being a society in which the prevention of waste is a virtue？

so much contradictory, sometimes incorrect advice about exercising that you become confused. Test yourself on the following true false quiz. It will tell you what you need to know.

1. To lose weight you should always "work up a good sweat" when exercising.

False. Sweating only lowers body temperature to prevent overheating; it does not help you reduce weight. You may weigh less immediately after a workout, but this is due to water loss. Once you replace the liquid, you replace the weight.

2. You burn more calories jogging one mile than walking the same distance.

False. You use the same amount of energy whether you walk or jog the mile, since in both cases you are moving the same weight the same distance. The speed doesn't matter. Of course, if you jog rather than walk for 30 minutes, you'll cover more distance, and therefore burn more calories.

3. If your breathing doesn’t return to normal within minutes after you finish exercising, you' ve exercised too much.

True. Five minutes or so after exercising, your breathing should be normal, your heart shouldn't be pounding, and you shouldn’t be exhausted. Beneficial exercise is not too difficult, unpleasant, and exhausting; it is enjoyable and refreshing.

4. Walking is one of the best exercises.

True.. Walking helps circulation of blood throughout the body, and thus has a direct effect on your overall feeling of health.
