Early or Later Day CareThe British psychoanalyst John Bowlby maintains that separation fro

Early or Later Day Care

The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's 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 between children and parents found in modem societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, (he 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 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 American studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.

But Bowlby's analysis raises the possibility 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. 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 from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.

Which of the following statements would Bowlby support?

A.Statistical studies should be carried out to assess the positive effect of day care for children at the age of three or older.

B.Early day care can delay the occurrence of mental illness in children.

C.The first three years of one's 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.

听力原文:In 1968, the city of Philadelphia, Pennsylvania, had a problem. The city's school

听力原文: In 1968, the city of Philadelphia, Pennsylvania, had a problem. The city's school system needed a new school building and teachers but did not have the money to pay for this multi-million-dollar project. City officials solved the problem in a unique way. They decided to use the many scientific and cultural institutions in the city and the classrooms. Experts who worked in the various institutions would be the teachers. About 100 institutions in Philadelphia--public, private, and commercial--helped the Program. The experiment in education, known as the Parkway Program, began in February 1969. John Bremer, an Englishman and education innovator, planned the program and became its director. The Program had grown in size from 142 to 500 high school students and is so popular that thousands of applicants are denied places each year. The Program gives a freedom to high school education never known before. Besides basic courses required for a diploma--languages, history, science--students may choose from more than a hundred other courses. Any subject will be offered if an instructor can be found. Every group of 15 boys and girls belong to a "tutorial group", led by a teacher and one assistant. Students in the Program say that school is no longer a place but an interesting activity.

(33)

A.City officials.

B.Experts in various institutions.

C.Newly-graduated university students.

D.Some famous scientists.

仔细阅读1:More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz

More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge to a new situation but a quality was not the ability to retain facts or apply prior knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (through the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas.

The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues of interdependence between eagles("How big are they?" and "What do they eat?"). The college students had cultivated the ability to ask questions, the cornerstone of critical thinking. They had learned how to learn.

Museums and other institutions of informal learning may be better suited to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit-asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit. Rather than merely asking about something they wanted to try, they tended to include both cause and effect in their question. Asking juicy questions appears to be a transferable skill for deepening collaborative inquiry into the science content found in exhibits.

This type of learning is not confined to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form. and pursue their own questions and too much ground to cover in the curriculum. But people must acquire this skill somewhere. Our society depend on them being able to make critical decisions about their own medical treatment, says, or what we must do about global energy needs and demands. For that, we have a robust informal system that gives no grades, takes all comers, and is available even on holidays and weekends.

56.What is traditional educators' interpretation of the search outcome mentioned in the first paragraph?

A.Students are not able to apply prior knowledge to new problems

B.College students are no better than fifth graders in memorizing issues.

C.Education has not paid enough attention to major environmental issues.

D.Educated has failed to lead students to think about major scientific ideas.

57.In what way are college students different from children?

A.They have learned to think critically

B.They are concerned about social issues

C.They are curious about specific features.

D.They have learned to work independently

58.What is benefit of asking questions with no ready answers?

A.It arouse students' interest in things around them.

B.It cultivates students' ability to make scientific inquiries.

C.It trains students' ability to design scientific experiments.

D.It helps students realize not every question has an answer

59.What is said to be the advantage of informal learning?

A.It allows for failures

B.It is entertaining

C.It charges no tuition

D.It meets practical need.

60.What does author seem to encourage educators to do at the end of the passage?

A.Train students to think about global issues.

B.Design more interactive classroom activities.

C.Make full use of informal learning resources.

D.Include collaborative inquiry in the curriculum.

World leaders met recently at United Nations headquarters in New York City to discuss the
environmental issues raised at the Rio Earth Summit in 1992. The heads of state were supposed to decide what further steps should be taken to halt the decline of Earth's life-support systems. In fact, this meeting had much die flavour of the original Earth Summit. To wit: empty promises, hollow rhetoric, bickering between rich and poor, and irrelevant initiatives. Think U. S. Congress in slow motion.

Almost obscured by this torpor is the fact mat there has been some remarkable progress over the past five years—real changes in the attitude of ordinary people in me Third World toward family size and a dawning realisation mat environmental degradation and their own well-being are intimately, and inversely, linked. Almost none of this, however, has anything to do with what the bureaucrats accomplished in Rio.

Or it didn't accomplish. One item on the agenda at Rio, for example, was a renewed effort to save tropical forests.(A previous UN-sponsored initiative had fallen apart when it became clear that it actually hastened deforestation.)After Rio, a UN working group came up with more than 100 recommendations that have so far gone nowhere. One proposed forestry pact would do little more than immunizing "wood-exporting nations against trade sanctions.

An effort to draft an agreement on what to do about the climate changes caused by CO2 and other greenhouse gases has fared even worse. Blocked by the Bush Administration from setting mandatory limits , the UN in 1992 called on nations to voluntarily reduce emissions to 1990 levels. Several years later, it's as if Rio had never happened. A new climate treaty is scheduled to be signed this December in Kyoto, Japan, but governments still cannot agree on these limits. Meanwhile, the U. S. produces 7% more CO2 than it did in 1990, and emissions in the developing world have risen even more sharply. No one would confuse the "Rio process" with progress.

While governments have dithered at a pace that could make drifting continents impatient, people have acted. Birth-rates are dropping faster than expected, not because of Rio but because poor people are deciding on their own to reduce family size. Another positive development has been a growing environmental consciousness among the poor. From slum dwellers in Karachi, Pakistan, to colonists in Rondonia, Brazil, urban poor and rural peasants alike seem to realize that they pay the biggest price for pollution and deforestation. There is cause for hope as well in the growing recognition among business people that it is not in their long-term interest to fight environmental reforms. John Browne, chief executive of British Petroleum, boldly asserted in a major speech in May that the threat of climate change could no longer be ignored.

The writer's general attitude towards the world leaders meeting at the UN is .

A.supportive

B.impartial

C.critical

D.comedic

Sunlight is free, but that is no reason to waste it. Yet even the best silicon solar cells
—by far the most【C1】______sort—convert only a quarter of the light that falls on them. Silicon has the【C2】______of being cheap: manufacturing improvements have brought its price to a point where it is snapping at the heels of fossil fuels.【C3】______many scientists would like to replace it【C4】______something fundamentally better. John Rogers, of the University of Illinois, Urbana-Champaign, is one. The cells he has【C5】______can convert 42.5% of sunlight.【C6】______improved, Dr Rogers reckons, their efficiency could rise to 50%. Their【C7】______is that they are actually not one cell, but four, stacked one on top of another. Solar cells are made of semiconductors, and every type of semiconductor has a【C8】______called a band gap that is different from that of other semiconductors. The band gap【C9】______the longest wavelength of light a semiconductor can absorb (it is transparent to longer wavelengths). It also fixes the【C10】______amount of energy that can be【C11】______from shorter wavelength. The result is that long-wavelength photons are lost and short-wave ones incompletely utilised. Dr Rogers【C12】______this by using a different material for each layer of the stack. He chooses his materials【C13】______the bottom of the band gap of the top layer matches the top of the band gap of the one underneath, and so on【C14】______the stack. Each layer thus【C15】______off part of the spectrum, converts it efficiently into electrical energy and passes the rest on. The problem is that the materials needed to make these semiconductors are【C16】______But Dr Rogers has found a way to overcome this.【C17】______solar-cell modules are completely covered by semiconductor, but in his only 0.1% of the surface is so covered. The semiconducting stacks, each half a millimeter square, are【C18】______over that surface many dots. Each stack then has a pair of cheap glass lenses【C19】______over it. These focus the suns light onto the stack, meaning that all【C20】______light meets a semiconductor.

【C1】

A.conventional

B.common

C.peculiar

D.humble
