　　英语四级听力美文第50篇:Stress

　　As the pace of life continues to increase in the modern society, we are fast losing the art ofrelaxation.Once you are in the habit of rushing through life, being on the go from morning tillnight, it is very hard to slow down.But relaxation is essential for a healthy mind andbody.Stress is a natural part of everyday life and there is no way to avoid it.In fact, it is not thebad thing it is often supposed to be.A certain amount of stress is vital to provide one withmotivation and give purpose to life.It is only when the stress gets out of control that it canlead to poor performance and ill health.The amount of stress a person can withstanddepends very much on the individual.Some people are not afraid of stress at all, and suchcharacters are obviously prime material for managerial responsibilities.Others lose heart at thefirst signs of unusual difficulties.When exposed to stress, in whatever form, we react bothchemically and physically.In fact we make a choice between" flight" or" fight".In moreprimitive days the choices made the difference between life or death.The crises we meet todayare unlikely to be so extreme, but however little the stress, it involves the same response.Itis when such a reaction lasts long, through continued exposure to stress, that healthbecomes endangered.Such serious conditions as high blood pressure and heart disease haveestablished links with stress.Since we can not remove stress from our lives( it would beunwise to do so even if we could),we need to find ways to deal with it in order that we can stayhealthy in mind and body.
