英语专四听力短篇练习资料：

Our Concern

The histoly of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth\'s vegetation and its animal life have been molded by the environment. Only in the present century has one species of man acquired significant power to alter the nature of his world.

The rapidity of change follows the pace of man rather than the pace of nature. Radiation is now the unnatural creation of man\'s tampering with the atom. The chemicals are the creations of man’s inventive mind, having no counterparts in nature.

We have put poisonous and biologically potent chemicals into the hands of persons largely ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. We have allowed these chemicals to be used with little or no advance investigation of their effect. Future generations are unlikely to forgive our lack of concern. (170 words)

Sleep

Why is it so difficult to fall asleep when you are overtired? There is no one answer that applied to every individual. It is possible to feel "tired" physically and still be unable to fall asleep, because while your bocdy may be exhausted, you do not feel sleepy. It is not so easy to simply "turn off".

Lack of sleep complicates matters even more. Experts say adults need at least seven to eight hours of sleep a night to function properly. When you get less sleep than that on consecutive three nights, you begin to accrue four "sleep debt". As sleep debt increases your body experiences a stress response. Now a vicious cycle has been created: You experience the feeling of being more and more tired, but your body is increasingly stimulated. "Power sleeping" for more hours on weekends is only a temporary solution. There is no substitute for getting a good night\'s sleep on a regular basis. (158 words)
