单选题Passage Four The classic difficulty felt with democracy arises from the fact that democracy can never express the will of the whole people because there never exists any such unchanging will (at least in any society that call itself democratic). The concept of government of the whole people by the whole people must be looked on as being in the poetry rather than in the prose of democracy; the fact of prose is that real democracy means government by some kind of dominant majority. And the ever-present danger, repeatedly realized in fact, is that this dominant majority may behave toward those who are not of the majority in such a manner as to undermine the moral basis of the right of people, because they are people, to have some important say in the setting of their own course and in the use of their own faculties. Other forms of government may similarly fail to respect human independence. But there is at least no contradiction in that; the underlying assumption of every kind of government by wisers and betters is that people on the whole are not fit to manage their own affairs, but must have someone else do it for them, and there is no paradox when such a government treats its subjects without respect, or deals with them on the basis of their having no rights that the government must take into account. But democracy affirms that people are fit to control themselves, and it cannot live in the same air with the theory that there is no limit to the extent to which public power—even the power of a majority--can interfere with the lives of people. Rational limitation on power is therefore not a contradiction to democracy, but is of the very essence of democracy as such. Other sorts of government may impose such limitations on themselves as an act of grace. Democracy is under the moral duty of limiting itself because such limitation is essential to the survival of that respect for humankind which is in the foundations of democracy. Respect for the freedom of all people cannot, of course, be the only guide, for there would then be no government. Delicate ongoing compromise is what must be looked for. But democracy, unless it is to deny its own moral basis, must accept the necessity for making this compromise and for giving real weight to the claims of those without the presently effective political power to make their claims prevail in elections.

单选题Passage 8 Researchers are increasingly interested in manipulating the environment early in children's lives when they are perceived to be at risk for impoverished intelligence. In a program conducted in North Carolina by Craig Ramey and his associates, pregnant women with IQs averaging 80 were recruited for a study. After their babies were born,half of the infants were cared for during the day at an educational daycare center and half were reared at home by their mothers; both groups of children were given medical care and dietary supplements, and their families were given social services if they requested them. At the age of 3, the children who attended the educational daycare center had significantly higher IQs than did the home-reared children. This difference was likely due to the decline in the IQs of the home-reared children during the period from 12 to 18 months of age. By the time the children were 5 years old, 39 percent of the home-reared children had IQs below 85 but only 11 percent of the educational day-care children had IQs this low. In the most recent evaluation of this project, positive effects of educational daycare on the intellectual development and academic achievement of the children were evident at age 12. Some parents, such as those in Ramey's study, have difficulty providing an adequate environment for the intellectual needs of their infants. Once these difficulties are a reoccurring part of the family system, changing efforts probably will be more difficult and costly; early intervention in the family system is directed at changing parental adaptive and responsive functioning so that permanent negative effects are minimized. In another investigation, the Infant Health and Development Program, early intervention with low-birth weight children revealed that both home visitation and an educational child curriculum improved the children's IQ, decreased behavior problems, and improved the home environment. The intervention was more effective with mothers with low educational attainment than those with high educational attainment, more effective for African American than White children, and effective for most at-risk children. Intervention programs have the most positive effects on children's well-being when they (a) begin as early as possible, (b) provide services to parents as well as to the child, (c) have a low child-teacher ratio, (d) have high parental involvement, and (e) have frequent contacts. In one review of family intervention studies, intervention was more effective when there were eleven or more contacts between the intervener and the family; while eleven sessions is a somewhat arbitrary number, it does indicate that a certain duration of contact is necessary for intervention success.

单选题One of the most eminent of psychologists, Clark Hull, claimed that the essence of reasoning lies in the putting together of two "behavior segments" in some novel way, never actually performed before so as to reach a goal. Two followers of Clark Hull, Howard and Tracey Kendler, (1) a test for children that was explicitly based on Clark Hull's principles. The children were given the (2) of learning to operate a machine so as to get a toy. In order to succeed they had to go through a two-stage (3) . The children were trained on each stage (4) . The stages consisted merely of pressing the correct one of two buttons to get a marble; and of (5) the marble into a small hole to release the toy. The Kendlers found that the children could learn the separate bits readily enough. (6) the task of getting a marble by pressing the button they could get the marble; given the task of getting a toy when a marble was handed to them, they could use the marble. (All they had to do was put it in a hole.) (7) they did not for the most part "integrate", to use the Kendlers' terminology. They did not press the button to get the marble and then (8) without further help to use the marble to get the toy. So the Kendlers concluded that they were incapable of deductive (9) . The mystery at first appears to deepen when we learn, from (10) psychologist, Michael Cole, and his colleagues, that adults in an African culture apparently cannot do the Kendlers' task either. But it lessens, (11) , when we learn that a task was devised which was (12) to the Kendlers' one but much easier for the African males to handle. (13) the button-pressing machine, Cole used a locked box and two (14) colored match-boxes, one of which contained a key that would open the box. Notice that there are still two (15) segments—"open the right matchbox to get the key" and "use the key to open the box"—so the task seems formally to be (16) . But psychologically it is quite different. Now the subject is dealing not with a strange machine but with familiar meaningful objects; and it is clear to him what he is meant to do. It then (17) that the difficulty of integration is greatly reduced. Recent work by Simon Hewson is of great interest here for it shows that, for young children, (18) , the difficulty lies not in the (19) processes which the task demands, but in certain perplexing features of the apparatus and the procedure. When these are changed in ways which do not at all affect the inferential nature of the problem, then five-year-old children solve the problem (20) college students did in the Kendlers' own experiments.

单选题While still catching up to men in some fields of modern life, women appear to be far ahead in at least one undesirable aspect. " Women are particularly liable to developing depression and anxiety disorders in response to stress compared to men. " according to Dr. Yehuda, chief psychiatrist at New York's Veteran's Administration Hospital. Studies of both animals and humans have shown that sex hormone(荷尔蒙) somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions. In several of the studies, when stressed-out female rats had their ovaries (the female reproductive organs) removed, their chemical responses became equal to those of the males. Adding to a woman's increased dose of stress chemicals, are her increased "opportunities" for stress. "It's not necessarily that women don't cope as well. It's just that they have so much more to cope with. " says Dr. Yehuda. "Their capacity for tolerating stress may even be greater than men's," she observes, "it's just that they're dealing with so many more things that they become worn out from it more visibly and sooner. " Dr. Yehuda notes another difference between the sexes. " I think that the kinds of things that women are exposed to tend to be in a chronic or repeated nature. Men go to war and are exposed to combat stress. Men are exposed to more acts of random physical violence. The kinds of interpersonal violence that women are exposed to tend to be in domestic situations, by, unfortunately, parents or other family members, and they tend not to be one-shot deals. The wear-and-tear that comes from these longer relationships can be quite devastating. " Adeline Alvarez married at 18 and gave birth to a son, but was determined to finish college. "I struggled a lot to get the college degree. I was living in so much frustration that that was my escape, to go to school, and get ahead and do better. " Later, her marriage ended and she became a single mother. "It's the hardest thing to take care of a teenager, have a job, pay the rent, pay the car payment, and pay the debt. I lived from paycheck to paycheck. " Not everyone experiences the kinds of severe chronic stresses Alvarez describes. But most women today are coping with a lot of obligations, with few. breaks, and feeling the strain. Alvarez's experience demonstrates the importance of finding ways to diffuse stress before it threatens your health and your ability to function.
