Plants and Mankind

    Botany(植物学), the study of plants, occupies a peculiar position in the history of human knowledge. We don’t know what our Stone Age 1 ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient 2. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes 3, Medicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon 4 recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of “knowledge 5” at all.

    Unfortunately, the more industrialized we become the farther away we move from direct contact with plants. And the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid 6. When our Neolithic 7 ancestors, living in the Middle Eastabout 10,000years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away 8.

Heat and Health

Extremely hot weather is common in many parts of the world. Although hot weather just makes most people hot, it can cause medical problems--and death.
Health experts say that since the year 1900, extremely hot weather has killed more people in the United States than any other natural event. One year--the unusually hot summer of 1980--heat caused about 1,700 deaths in the United States. In 1995, more than 600 people died in a similar heat wave in one city--Chicago.
To measure extreme heat, government weather experts have developed the Mean Heat Index. It measures the average of how hot it is felt all day on an extremely hot day. Experts say it is the total heat of a hot day or several hot days that can affect health. Several hot days are considered a heat wave. Experts say heat waves often become deadly when the nighttime temperature does not drop much from the highest daytime temperature.
The most common medical problem caused by hot weather is heat stress. Usually, it also is the least severe. For most people, the only result of heat stress is muscle pain. The pain is a" warning that the body is becoming too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt. For some people, however, the result is much more serious.
For example, doctors say some people face a greatly increased danger from heat stress. These people have a weak or damaged heart, high blood pressure, or other problems of the blood system. Severe heat can help cause a heart attack or stroke. Health experts say this is the most common cause of death linked to hot weather.
What can people learn from the Mean Heat Index

A:The average temperature of an extremely hot day. B:The highest temperature of an extremely hot day. C:The lowest temperature of an extremely hot day. D:The nighttime temperature of an extremely hot day.
