Over sixty years ago, Dr. Hans Selye recognized the mind-body connection involved with stress, as all of his patients had similar physiological and psychological characteristics. Studies done with laboratory rats found that these same physical responses existed with animals when they were put under stress. He came to the conclusion that stress is "the non-specific response of the body to any demand placed upon it". He concluded that each demand made on the body is unique in that there is a definite response: when we are cold, we shiver; when we are hot we perspire; a great muscular effort increases the demands upon the heart and vascular system.
Selye claimed that it was not stress that harmed us, but distress, and distress occurred when we prolonged emotional stress and didn't deal with it in a positive manner. Selye was the pioneer in research into stress in the 1930s, and is internationally acknowledged as "the father of the stress field'. After publishing the first scientific paper to identify and define "stress" in 1936, Selye wrote more than 1700 scholarly papers and 39 books on the subject. At the time of his death 1982, his work had been cited in more than 362,000 scientific papers, in countless popular magazine stories, and in most major languages. Selye held three earned doctorates (M. D. , Ph. D. , D. Sc. ) plus 43 honorary doctorates, tie was an elected member of several dozen of the world's most recognized medical and scientific associations.
After completion of his academic and professional studies in Prague, Paris, and Rome, Selye received a Rockefeller Research Fellowship and accepted a position at Johns Hopkins University in Baltimore, Maryland. By 1945 he had become the first Director of tile Institute of Experimental Medicine and Surgery at the University of Montreal, Canada. He served in that position until his retirement in 1976. Subsequently he established the International Institute of Stress. He recognized that strain, or stress, plays a very significant nile in the development of all types of disease. Selye called the process whereby strain influences the body, the General Adaptation Syndrome. He concluded that there are three distinctive phases in this process: alarm, resistance, and exhaustion. He wrote of two types of stress: pleasant stress contributing to human well-being, and unpleasant stress contributing to disease. He is still by far the world's most frequently cited author on stress topics.
What does the passage mainly discuss？
A．Selye's professional life and achievements.
B．The origins of the word "stress".
C．Defining stress.
D．The father of the stress field.

Passage Four:Questions 26 to 30 are based on the following passage.Even plants can run a fever, especially when they’re under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adapting the infrared (红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest (害虫) problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States,” says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
第26题：Plants will emit an increased amount of heat when they are ________.
A) sprayed with pesticides
B) facing an infrared scanner
C) in poor physical condition
D) exposed to excessive sun rays

Despite the general negative findings, it is important to remember that all children who live through a divorce do not behave in the same way. The specific behavior. depends on the child's individual personality, characteristics, age at the time of divorce, and gender. In terms of personality, when compared to those rated as relaxed and easygoing, children described as temperamental and irritable have more difficulty coping with parental divorce, as indeed they have more difficulty adapting to life change in general. Stress, such as that found in disrupted families, seems to impair the ability of temperamental children to adapt to their surroundings, the greater the amount of stress, the less well they adapt. In contrast, a moderate amount of stress may actually help an easygoing, relaxed child learn to cope with adversity.
There is some relationship between age and children's characteristic reaction to divorce. As the child grows older, the greater is the likelihood of a free expression of a variety of complex feelings, an understanding of those feelings, and a realization that the decision to divorce cannot be attributed to any one simple cause Self-blame virtually disappears after the age of 6, fear of abandonment diminishes after the age of 8, and the confusion and fear of the young child is replaced in the older child by shame, anger, and self-reflection. Gender of the child is also a factor that predicts the nature of reaction to divorce, the impact of divorce is initially greater on boys than on girls. They are more aggressive, less compliant, have greater difficulties in interpersonal relationships, and exhibit problem behaviors both at home and at school. Furthermore, the adjustment problems of boys are still noticeable even two years after the divorce.
Girls' adjustment problems are usually internalized rather than acted out, and are often resolved by the second year after the divorce. However, new problems may surface for girls as they enter adolescence and adulthood. How can the relatively greater impact of divorce on boys than on girls be explained？ The greater male aggression and noncompliance may reflect the fact that such behaviors are tolerated and even encouraged in males in our culture more than they are in females. Furthermore, boys may have a particular need for a strong male model of self-control, as well as for a strong disciplinarian parent. Finally, boys are more likely to be exposed to their parents' fights than girls are, and after the breakup, boys are less likely than girls to receive sympathy and support from mothers, teachers, or peers.
Temperamental, irritable kids have difficulty adapting to parental divorce because
A．they care too much about the life change.
B．the great stress of their families diminishes their ability.
C．they tend to lose temper easily and are sensitive to the life change.
D．they are faced with more parents' fights than the relaxed, easygoing children.
