2020年9月英语四级听力赏析三篇
【篇一】
Believe or not, 43,000,000 Americans are gardening. That is about one in six. Gardeners, of course, come in many varieties. Not surprisingly, most of them are people who live in the suburbs, and enjoy planting flowers, or maybe a small vegetables garden.
The average age of gardeners in America is about 45 years old; they usually fall somewhere in the middle class. But the fastest growing groups are city dwellers. Urban residents are finding ways of gardening even in their crowded areas. Many go to large public gardens, as a place designed by the city for garden, and you can actually ranch your own plot.
Still other people use their balconies or roof tops, wherever they can find the space to plant small patches of green.
Useful Words and Expressions:
1. suburb 郊区
2. dweller 居民
3. ranch 经营牧场
4. balcony 阳台
5. patch小块地
【篇二】
The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical fomp3 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 hamp3. We have subjected enomp3ous numbers of people to contact with these enomp3ous 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.
Useful Words and Expressions:
1. interaction 交互作用，交感
2. vegetation 植被
3. mold 塑造，浇铸
4. species 种类
5. unnatural 不自然的
6. temper with 损害，影响
7. counterpart 配对物
8. poisonous 有毒的
9. potent 有力的，有效的
【篇三】
Why is it so difficult to fall asleep when you are overtired? There is no one answer that applies to every individual. It is possible to feel “tired” physically and still be unable to fall asleep, because while your body 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.
Useful Words and Expressions:
1. overtire 使过度疲劳
2. apply to 将……应用于
3. consecutive 连续的，连贯的
4. accrue 自然增加，产生
5. vicious恶的
vicious cycle 恶性循环
6. stimulate 刺激，激励
7. substitute for 代替……，替换……
