题目内容

For many years doctors have warned us about the dangers of stress and have given us advice about how to cut down our stress levels. Everyone agrees that long-term（长期的）stress, for example, having to look after someone who has been ill for a long time, or stressful situations, for example, being stopped in a traffic jam, is bad for our health and should be avoided(避免)whenever possible.

However, some medical experts now believe that certain kinds of stress many actually be good for us.

　 Dr. Dirk Marion, an anti-ageing expert, says that "good stress" is helpful to our health. And in fact, it may help us stay young and attractive and even live longer.

　 According to Dr. Marion, running for a bus or having to work to a deadline(最后期限)are examples of "good stress", which are situations with short-term, low or moderate(适度的)stress. The stress usually makes us react quickly and efficiently, and gives us a sense of　achievement-we did it!

Other stressful activities that Dr. Marion recommends as being good stress include cleaning your room over a weekend, packing your suitcase in a hurry to the train station on time, or shopping for a party during your lunch break.

So next time your teacher tells you that she wants to see your homework finished and on her desk in 45 minutes, don't be worried or nervous; just think of it as "good stress" which will be helpful for your long-term health!
