32、r answers on ANSWER SHEET 1.BText 1/BThe British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive “attachment“ period from birth to three may sear a childs personality and predispose to emotional problems in later life. Some people have drawn the conclusion f
33、rom Bowlbys work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion.Firstly, anthropologists point out that the insulated love affair b
34、etween children and parents found in modern societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone-far from it. Secondly, common sense tells us that day care would not be so
35、 widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful Amer
36、ican studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on childrens development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.But Bowlbys analysis raises the p
37、ossibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with.
38、 Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far
39、from clear-out, though experience and available evidence indicate that early care is reasonable for infants.（分数：5.00）(1).Which of the following statements would Bowlby support?（分数：1.00）A.Statistical studies should be carried out to assess the positive effect of day care for children at the age of th
40、ree or older.B.Early day care can delay the occurrence of mental illness in children.C.The first three years of ones life is extremely important to the later development of personality.D.Children under three get used to the life at nursery schools more readily than children over three.(2).Which of t
41、he following is derivable from Bowlbys work?（分数：1.00）A.Mothers should not send their children to day care centers until they are three years of older.B.Day care nurseries have positive effects on a childs development.C.A child sent to a day care center before the age of three may have emotional prob
42、lems in late life.D.Day care would not be so popular if it has noticeable negative effects on a childs personality.(3).It is suggested that modem societies differ from traditional societies in that _ .（分数：1.00）A.the parents-child relationship is more exclusive in modem societiesB.a child more often
43、grows up with his/her brothers or sisters in traditional societiesC.mother brings up children with the help of her husband in traditional societiesD.children in modem societies are more likely to develop mental illness in later years(4).Which of the following statements is NOT an argument against Bo
44、wlbys theory?（分数：1.00）A.Many studies show that day care has a positive effect on childrens developmentB.Day care is safe, otherwise there wouldnt be so many nursery schools.C.Separation from parents for very young children is common in some traditional societies.D.Parents find the immediate effects
45、of early day care difficult to deal with.(5).Which of the following best expresses the writers attitude towards early day care?（分数：1.00）A.Children under three should stay with their parents.B.Early day care has positive effects on childrens development.C.The issue is controversial and its settlement
46、 calls for the use of statistics.D.The effects of early day care on children are exaggerated and parents should ignore the issue.BText 2/BAtmospheric pressure can support a column of water up to 10 meters high. But plants can move water much higher: the sequoia tree can pump water to its very top, m
47、ore than 100 meters above the ground. Until the end of the nineteenth century, the movement of water in trees and other tall plants was a mystery. Some botanists hypothesized that the living cells of plants acted as pumps. But many experiments demonstrated that the stem of plants in which all the cells are killed can still mo
