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".

However, biological understanding is not enough:【B2】itself, it can never tell us what human beings are.【B3】to our physical equipment—the naked human body—we are not an【B4】animal. We are tropical creatures,【B5】hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us get it. In the purely physical【B6】, our species seems a poor【B7】for survival. But we have survived—survived and multiplied and【B8】the earth. Some day we will have a【B9】living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things？ Part of the answer is physical.【B10】its limitations, our physical equipment has some important potentials. Inhabitants of our eventual moon colony will bring their own food and oxygen and then create an artificial earth environment to supply necessities. 【B1】 A．processes B．acts C．modes D．procedures
