1.The sun sends out huge amounts of energy, not only to Earth, but to all other planets in the solar system and directly into space. The source of all that energy is nuclear fusion (核聚变) occurring at the sun’s core. The Large Helical Device being developed at the Ministry of Educational Institute for Fusion Science (NIFS) is essentially an “artificial sun” that aims to reproduce this nuclear fusion on Earth.“Nuclear fusion is a reaction in which nuclei of light atoms such as hydrogen combine to form nuclei of heavier atoms such as helium (氦). If we can utilize the huge amounts of energy released by this reaction, nuclear fusion will then constitute a completely new, clean and never ending source of energy,” says NIFS Director Atsui Iiyoshl. In many respects, fusion is far superior to the various conventional energy sources currently in use.Fusion seems to have tremendous potential as a new source of energy. But to produce fusion reactions on Earth, it is necessary to meet a set of critical plasmatic (等离子区) conditions, including ultra-high temperatures of 100 million degrees or so centigrade - a state that refuses to imagine. To meet this challenge, Japanese scientists have come up with their own unique helical device that is particularly safe and is suitable for continuous operation.The large Helical Device now being developed is expected to be completed by the end of next year, with experiments scheduled to start at the beginning of 1998.(5分)1.1The phrase “artificial sun” in the first paragraph probably means “________”.(1分)A. a man-made sun B. NIFSC. the sun’s energyD. fusion science

4. Present pension structures no longer work. They were established in a more youthful period with relatively few older people who were often poor and iii, and generally spent only a short time in retirement. In rich countries today, older people are often well-off and in good health, and are spending around 20 years in retirement. Therefore there is the need for reform.This survey has presented the arguments for more private funding and for fairer pensions. Such changes will create motives for individuals to take charge of their own retirement needs rather than leaving the task to the state. This, in turn, will make the provision of public pensions more afford- able.Even so, the state will continue to play a leading role in pensions. At a minimum, governments must offer a safety net, probably in the form of a defined benefit financed through taxation, for people who for some reason have not been able to provide for themselves and who would otherwise be miserable in old age. More broadly, there is a case for the state to offer a slimmed-down pay-as-you-go pension system, although as far as possible this should be organized along defined-contributions lines. Such provision widens the range of assets to include human capital because the effective return comes from total wages, and offers a safe if low return.Governments also have to create a suitable framework for effective private pensions. Administrative(行政的)expenses have to be tightly controlled, and appropriate tax motives have to be offered to encourage voluntary pension saving. Where the state provides a generous safety net, private-pension saving may have to be made mandatory(强制的), otherwise many people will not bother.So much for the developed countries, but what of the more youthful populations of tile rest of the world? In 1994, the World Bank came down heavily in favor of more funding in private accounts. It thought the state's role should be to provide a smallish first pillar with the limited task of providing protection against old-age poverty, and to command a privately-funded second pillar to provide the bulk of pensions.(5分)4.1 More private funding and fairer pensions____.(1分)A. can urge people to save more private-pensionsB. may be financed through taxC. can lessen the burden of the stateD. can provide more public pensions
4.3 To create a proper framework for effective private pensions, the government should____.(1分)

2.The Crying GameAll normal human infants cry, although they vary a great deal in how much. A mysterious and still unexplained phenomenon is that crying tends to increase in the first few weeks of life, peak in the second or third month, and then decrease. Some babies in the United States cry so much during the peak period-often in excess of three hours a day-and seem so difficult to soothe that parents come to doubt their nurturing skills or begin to fear that their offspring (子孙后代) is suffering from a painful disease. Some mothers discontinue nursing and switch to bottle-feeding because they believe their breast milk is insufficiently nutritious and that their infants are always hungry. In extreme cases, the crying may provoke physical abuse, sometimes even precipitating (使发生) the infant's death.A look at another culture, the Kung San hunter-gatherers of southern Africa, provides us with an opportunity to see whether care-giving strategies have any effect on infant crying. Both the Kung San and Western infants escalate (使增强) their crying during the early weeks of life, with a similar peak at two or three months. A comparison of Dutch, American, and Kung San infants shows that the number of individual crying episodes are virtually identical. What differs is their length: Kung San infants cry about half as long as Western babies. This implies that care-giving can influence only some aspects of crying, such as duration.What is particularly striking about child-rearing among the Kung San is that infants are in constant contact with a caregiver; they are carried or held most of the time, are usually in an upright position, and are breast-fed about four times an hour for one to two minutes at a time. Furthermore, the mother almost always responds to the smallest cry or fret (烦躁) within ten seconds.I believe that crying was adaptive for our ancestors. As seen in the contemporary Kung San, crying probably elicited a quick response, and thus consisted of frequent but relatively short episodes. This pattern helped keep an adult close by to provide adequate nutrition as well as protection from predators. I have also argued that crying helped an infant forge a strong attachment with the mother and-because new pregnancies are delayed by the prolongation of frequent nursing-secure more of her care-giving resources.In the United States, where the threat of predation has receded (降低) and adequate nutrition is usually available even without breast-feeding, crying may be less adaptive. In any case, care-giving in the United States may be viewed as a cultural experiment in which the infant is relatively more separated-and separable-from the mother, both in terms of frequency of contact and actual distance.The Western strategy is advantageous when the mother's employment outside of the home and away from the baby is necessary to sustain family resources. But the trade-off seems to be an increase in the length of crying bouts. (490 words)(5分)2.1Why does Western infants' crying tend to increase in the first few weeks of life and peak in the second or third month?____(1分)A. The infants suffer from a painful disease.B. Their parents lack nurturing skill.C. The reason is still unknown. D. Their parents abuse the infants physically.
