36、、 PART IV GRAMMAR next, the serotonin was injected directly into the brain or an artery in the neck. The pupils of the animals eyes narrowed and the electroencephalograms showed slow waves characteristic of deep sleep within five to ten minutes. More recently, Koella deprived cats of serotonin. The
37、animals, again equipped with implanted electrodes, were given PCPA, a drug that blocks the formation of serotonin. They wore then placed in small compartments fitted with one-way mirrors and watched round the clock. Normally cats sleep about 15 hours a day; but Koellas cats, after receiving PCPA, sp
38、ent about 30 minutes of each day sleeping. Most of the time, their EEGs showed the brain wave patterns of arousal. Occasionally the cats would curl up as if to go to sleep, but would soon get back on their feet to wander about. The animals showed signs of irritability and often meowed complainingly
39、after a few days of sleep deprivation, but had normal reflexes. The effects of the PCPA wore off eight days to two weeks after administration of the drug; the cats returned to their normal sleeping patterns as serotonin levels in their brains rose again. Koella believes that at least some types of c
40、hronic insomnia may be caused by a drop in brain-serotonin levels. The Worcester physiologist is now working on chemical ways to raise the brains serotonin levels and produce, in his words, “a truly physiological sleeping pill. “Synthetic sleeping pills, such as barbiturates, bring sleep, but at a p
41、rice: they depress the central nervous system, reduce heart action and respiration - and they can become habit-forming or even addictive. In one promising experiment toward the goal of letting the body “make its own pill,“ Koella has found that administration of 5-hydroxytryptophan, the chemical sub
42、stance from which the body derives serotonin, will quickly restore a normal sleeping pattern to cats lacking in serotonin. 86 The brain stem is located (Paragraph 2) _. （ A） in the hypothalamus （ B） between the brain and the spinal cord （ C） in the transmitter nerve cells （ D） between the hypothalam
43、us and the brain 87 The information in paragraph 5 indicates that PCPA was responsible for _. （ A） a lack of sleep （ B） the cats meowing （ C） normal sleeping patterns （ D） sleeping about 15 hours a day 88 The language used in this article indicates that Dr. Koella _. （ A） is positive that serotonin
44、controls sleep （ B） is quite uncertain whether serotonin controls sleep （ C） thinks that serotonin cant be extracted （ D） thinks that serotonin might control sleep 89 A good title for this article would be _. （ A） The Cats Want to Sleep （ B） I Cant Sleep Tonight （ C） How to Get Asleep （ D） Some New
45、Sleep Research 89 It is a curious paradox that we think of the physical sciences as “hard“ , the social sciences as “soft“, and the biological sciences as somewhere in between. This is interpreted to mean that our knowledge of physical systems is more certain than our knowledge of biological systems
46、, and these in turn are more certain than our knowledge of social systems. In terms of our capacity to sample the relevant universes, however, and the probability that our images of these universes are at least approximately correct, one suspects that a reverse order is more reasonable. We are able
47、to sample earths social systems with some degree of confidence that we have a reasonable sample of the total universe being investigated. Our knowledge of social systems, therefore, while it is in many ways extremely inaccurate, is not likely to be seriously overturned by new discoveries. Even the f
48、olk knowledge in social systems on which ordinary life is based in earning, spending, organizing, marrying, taking part in political activities, fighting and so on, is not very dissimilar from the more sophisticated images of the social system derived from the social sciences, even though it is buil
49、t upon the very imperfect samples of personal experience. In contrast, our image of the astronomical universe, of even of earths geological history, can easily be subject to revolutionary changes as new data comes in and new theories are worked out. If we define the “security“ of our image of various parts of the total system as the probability of their suffering significant changes, then we would reverse the ord
