What is a gifted child? There are different ways to define this term. It may refer to special talents in the arts  or to  a  high  level  of academic  abilities. A child  may  be gifted in one (81) area, such as music, or have talents in many areas. According to the U.S. National Association for Gifted Children, a gifted child shows an "exceptional level of performance” in one or more areas. In general usage, giftedness includes high levels of cognitive ability, motivation, inquisitiveness, creativity, and leadership. Gifted children (82) approximately 3 to 5 percent of the school-aged population. Although giftedness cannot be assessed by an intelligence test alone, these tests are often used to indicate giftedness. (83) giftedness begins at an IQ of 115, or about one in six children. Highly gifted children have IQs over 145, or about one in a thousand children. Profoundly gifted children have IQs over 180, or about one in a million children. Because very few education programs include any courses on teaching the gifted, teachers are often not able to recognize the profoundly gifted. Teachers are more likely to recognize moderately gifted children because they are ahead of the other children but not so far ahead as to be unrecognizable. For instance, children who can read older children's books in first and second grade are often transferred into gifted classes, but children (84) are reading adult books are told to stop reading them. Those profoundly gifted students who are not recognized often turn into discipline problems when they are not offered (85) ways to focus their extraordinary creativity.

The modern comic strip started out as ammunition in a newspapaer war between giants of the American press in the late nineteenth century. The first full-color comic strip appeared in January 1894 in
the New York World, owned by Joseph Pulitzer. The first regular weekly full-color comic supplement, similar to today’s Sunday funnies, appeared two years later, in William Randolph Hearst’ rival New York paper, the Morning Journal.
Both were immensely popular and publishers realized that supplementing the news with comic relief boosted the sale of papers. The Morning Journal started another feature in 1896, the “Yellow Kid”, the first continuous comic character in the United States, whose creator, Richard Outcault, had been lured away from the World by the ambitious Hearst. The “Yellow Kid” was in many ways a pioneer. Its comic dialogue was the strictly urban farce that came to characterize later strips, and it introduced the speech baloon inside the strip, usually placed above the characters’ heads.
The first strip to incorporate all the elements of later comics was Rudolph Dirks’s “Katzenjammer Kids”, based on Wilhelm Busch’s Max and Moritz, a European satire of the nineteenth century. The “Kids” strip, first published in 1897, served as the prototype for future American strips. It contained not only speech baloons, but a continuous cast of characters, and was divided into small regular panels that did away with the larger panoramic scenes of earlier comics.
Newspaper syndication played a major role in spreading the popularity of comic strips throughout the country. Though weekly colored comics came first, daily black-and-white strips were not far behind. The first appeared in the Chicago American in 1904. It was followed by many imitators, and by 1915 black-and-white comic strips had become a staple of daily newspapers around the country.

The green building movement, started in the 1970s as a way to reduce environmental destruction, is changing the way buildings are constructed. In the early years, green builders were a small minority, and their goals of reducing the environmental impact of buildings were considered unrealistic. Now, however, the movement is growing, as builders have been able to take advantage of new technology.
Green builders try to make use of recycled materials, which means less waste in dumps. Also, they reduce environmental impact by reducing the energy requirements of a building. One way is to provide an alternative, non-polluting source of energy. First, with solar panels, it is possible to produce electricity from the rays of the sun. Once installed, they provide energy at no cost and with no pollution.
Another solution is to reduce the amount of energy required in a building. It is possible to cut electricity use noticeably by improving natural lighting and installing low-energy light bulbs. To reduce the amount of fuel needed for heating or cooling, builders also add insulation to the walls so that the building stays warmer in winter and cooler in summer.
One example of this advanced design is the Genzyme Center of Cambridge, the most environmentally responsible office building in America. Every aspect of the design and building had to consider two things: the need for a safe and pleasant workplace for employees and the need to lessen the negative environmental impact. 75 percent of the building materials were recycled materials, and the energy use has been reduced by 43 percent and water use by 32 percent, compared with other buildings of the same size.
In other parts of the world, several large-scale projects have recently been developed according to green building principles. One of these is in Vauban, Germany, in an area that was once the site of army housing. The site has been completely rebuilt with houses requiring 30 percent less energy than conventional ones. These houses, heated by special non-polluting systems, are also equipped with solar panels.
A larger project is under way in China. The first phase of this project will include houses for 400 families built with solar power, non-polluting bricks, and recycled wall insulation. In a second phase, entire neighborhoods in six cities will be built. If all goes well, the Chinese government plans to copy these ideas in new neighborhoods across China.
Green building ideas, on a small or large scale, are spreading. Individuals, companies, and governments are beginning to see their benefits. Not only are they environmentally friendly, green buildings improve living and working conditions and also save money in the long run.

Early Teachers
All of you are enrolled in this introductory education course because you want to become teachers. I'd like to introduce this course with a little information about the life of a teacher a century ago. I hope you'll understand this information about early teachers, and I think you'll appreciate how much the life of a teacher has changed over the past century. 
Early in the twentieth century, the life of a teacher was quite different from what it is now. There were very strict rules that governed every aspect of the teacher's life. The rules weren't just about how a teacher could conduct herself in the classroom and on the school grounds. There were also numerous rules that governed just about everything a teacher did. 
Here are some of the rules. Teachers had to follow strict rules about their appearance; they were sometimes told not to wear colourful clothing, not to dye their hair or wear it loose, and not to wear their skirts above the ankle. Teachers' whereabouts during after-school hours were also strictly regulated; there were rules forbidding teachers to go to bars and to ice-cream parlors; there were rules requiring teachers to be home after 7:00 in the evening, and there were some rules forbidding them to leave town without permission. Just about any action a teacher wanted to take could be regulated. Teachers could be forbidden to smoke or to drink; they were also sometimes forbidden to spend time with men or to marry if they wanted to remain teachers.

The rules discussed in the lecture relate to what period of time?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

   The system of higher education had its origin in Europe in the Middle Ages, when the first universities were established. In modern times, the nature of higher education around the world, to some extent, has been determined by the models of influential countries such as France and Germany.

   Both France and Germany have systems of higher education that are basically administered by state agencies. Entrance requirements for students are also similar in both countries. In France, an examination called the baccalauréat is given at the end of secondary education. Higher education in France is free and open to all students who have passed this baccalauréat. Success in this examination allows students to continue their higher education for another three or four years until they have attained the first university degree called a licence in France.

   Basic differences, however, distinguish these two countries’ systems. French educational districts, called académies, are under the direction of a rector, an appointee of the national government who is also in charge of universities in each district. The uniformity in curriculum throughout the country leaves each university with little to distinguish itself. Hence, many students prefer to go to Paris, where there are better accommodations and more cultural amenities for them. Another difference is the existence in France of prestigious higher educational institutions known as grandes écoles, which provide advanced professional and technical training. Most of these schools are not affiliated with the universities, although they too recruit their students by giving competitive examinations to candidates. The grandes écoles provide rigorous training in all branches of applied science and technology, and their diplomas have a somewhat higher standing than the ordinary licence.

   In Germany, the regional universities have autonomy in determining their curriculum under the direction of rectors elected from within. Students in Germany change universities according to their interests and the strengths of each university. In fact, it is a custom for students to attend two, three, or even four different universities in the course of their undergraduate studies, and the majority of professors at a particular university may have taught in four or five others. This high degree of mobility means that schemes of study and examination are marked by a freedom and individuality unknown in France.

   France and Germany have greatly influenced higher education systems around the world. The French, either through colonial influence or the work of missionaries, introduced many aspects of their system in other countries. The German were the first to stress the importance of universities as research facilities, and they also created a sense of them as emblems of a national mind.

According to paragraph 4, what makes it possible for students in Germany to attend different universities during their undergraduate studies?

In the explosion of the linguistic life cycle, it is apparent that it is much more difficult to learn a second language in adulthood than a first language in childhood. Most adults never completely master a foreign language, especially in Phonology – hence the ubiquitous foreign accent. Their development often “fossilizes” into permanent error patterns that no teaching or correction can undo. Of course, there are great individual differences, which depend on effort, attitudes, amount of exposure, quality of teaching and plain talent, but there seems to be a cap for the best adults in the best circumstances
Many explanations have been advanced for children’s superiority; they exploit Motherese (the simplified, repetitive conversation between parents and children), make errors unself- consciously, are more motivated to communicate, like to conform, are not set in their ways, and have not first language to interfere. But some of these accounts are unlikely, based on what is known about how language acquisition works. Recent evidence is calling these social and motivation explanations into doubt. Holding every other factor constant, a key factor stands out: sheer age
Systematic evidence comes from the psychologist Elissa Newport and her colleagues. They tested Korean and Chinese – born students at the University of Illinois who had spent a least ten years in the United States. The immigrants were give a list of 276 simple English sentences, half of them containing some grammatical error. The immigrants who came to the United States between the age of 3 and 7 performed identically to American – born students. Those who arrived between ages 8 and 15 did worse the latter they arrived, and those who arrived between 17 and 39 did the worst of all, and showed huge variability unrelated to their age of arrival.

According to the passage, young children learn languages quickly for all of the following reasons EXCEPT

The human criterion for perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that it can spot a dime on the sidewalk while perched on top of the Empire State Building.
It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina. And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well in both the air and water because it is endowed with two foveae - areas of the eye, consisting mostly of cones, that provide visual distinctions. One fovea permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other fovea joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time.
A frog’s vision is distinguished by its ability to perceive things as a constant motion picture. Known as “bug detectors”, a highly developed set of cells in a frog’s eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn’t see them as food and would starve. The bee has a “compound” eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots, or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee’s eye also gauges flight speed. And if that is not enough to leave our 20/20 “perfect vision” paling into insignificance, the bee is capable of seeing something we can’t - ultraviolet light.
Thus, what humans consider to be “perfect vision” is in fact rather limited when we look at other species. However, there is still much to be said for the human eye. Of all the mammals, only humans and some primates can enjoy the pleasures of color vision.

According to the passage, why might birds and animals consider humans very visually handicapped?

Very few people in the modem world obtain their food supply by hunting and gathering in the natural environment surrounding their homes. This method of harvesting from nature’s provision is the oldest known subsistence strategy and has been practised for at least the last two million years. It was, indeed, the only way to obtain food until rudimentary farming and the domestication of wild animals were introduced about 10,000 years ago.
Because hunter-gatherers have fared poorly in comparison with their agricultural cousins, their numbers have dwindled, and they have been forced to live in marginal environments, such as deserts and arctic wastelands. In higher latitudes, the shorter growing seasons have restricted the availability of plant life. Such conditions have caused a greater dependence on hunting, and on fishing along the coasts and waterways. The abundance of vegetation in the lower latitudes of the tropics, on the other hand, has provided a greater opportunity for gathering a variety of plants. In short, the environmental differences have restricted the diet and have limited possibilities for the development of subsistence societies.
Contemporary hunter-gatherers may help US understand our prehistoric ancestors. We know from the observation of modem hunter-gatherers in both Africa and Alaska that a society based on hunting and gathering must be very mobile. While the entire community camps in a central location, a smaller party harvests the food within a reasonable distance from the camp. When the food in the area has become exhausted, the community moves on to exploit another site. We also notice seasonal migration patterns evolving for most hunter-gatherers, along with a strict division of labor between the sexes. These patterns of behavior may be similar to those practised by mankind during the Paleolithic Period.

   They call Jamaica the "Island in the sun" and that is my memory of it. Of sunshine, warmth and abundant fruit that was growing everywhere, and of love. There were two sisters ahead of me in the family, and though of course I didn't know it, there was an exciting talk of emigration, possibly to Canada but more usually to England, the land of opportunity. I guess that plans were already being made when I was born, for a year or so later my Dad left for London. Two years after that my mum went as well and my sisters and I were left in the care of my grandmother.

   Emigrating to better yourself was a dream for most Jamaicans, a dream many were determined to fulfill. Families were close and grandmothers were an important part of the family. So, when the mass emigrations began, it seemed perfectly right and natural for them to take over the running of families left behind.

   Grandmothers are often strict, but usually also spoil you. She ran the family like a military operation: each of us, no matter how young, had our tasks. Every morning, before we went to school, we all had to take a bucket appropriate to our size and run a relay from the communal tap to the barrels until they are full. My sisters had to sweep the yard before they went to school. My grandmother would give orders to the eldest and these were passed down- as I got older I found this particularly annoying! But I can tell you, no one avoided their duties.

   My Dad came over from England to see how we were getting on . He talked to us about the new country, about snow, about the huge city, and we all wanted to know more, to see what it was like. I didn't know it at that time., but he had come to prepare us for the move to England. Six months later my grandmother told me that I was going to join my parents and that she, too, was emigrating.

   London was strange and disappointing. There was no gold on the pavements, as the stories in Jaimaica had indicated. The roads were busy, the buildings were grey and dull, with many tall, high-rise blocks. It was totally unlike Jamaica, the houses all small and packed close together. In my grandmother's house I had a big bedroom, here I had to share.

   Then came the biggest shock: snow. While flakes came out of the sky and Dad smiled, pointed and said: "That's snow!" I rushed outside, looked up and opened my mouth to let the flakes drop in. The snow settled on my tongue and it was so cold that I cried. My toes lost all feeling. As my shoes and socks got wet and frozen, there came an excruciating pain and I cried with the intensity of it. I didn't know what was happening to me.

Astronomers have for the first time definitively ID’d the birth of a specific heavy element during a neutron-star smashup. They found strontium. And it showed up in the wavelengths of light — or spectra — making up this collision’s afterglow.
Scientists had assumed that a collision by two super-dense objects, such as neutron stars, would trigger a chain of nuclear reactions. They’re known as the r-process. In such an environment, the nuclei of atoms could rapidly gobble up neutrons. Afterward, those nuclei would become transformed in a process known as radioactive decay. The r-process was seen as a way to transform old, smaller elements into newer, bigger ones. About half of all elements heavier than iron were thought to be made in the r-process. Finding strontium in the recent collision at last offered the most direct evidence yet that neutron-star collisions really do trigger the r-process.
Physicists had long predicted that silver, gold and many other elements more massive than iron formed this way. But scientists weren’t sure where those r-process reactions took place. After all, no one had directly seen the r-process underway in a celestial event. Or they didn’t until the merger of two neutron stars in 2017. Scientists quickly analyzed light given off by that cataclysm. In it, they found evidence of the birth of a hodgepodge of heavy elements. All would seem to have come from the r-process. 
The researchers were examining mostly very heavy elements — ones whose complex atomic structures can generate millions of spectral features. And all of those features were not yet fully known, Watson points out. This made it extremely difficult to tease apart which elements were present, he says.
Strontium, however, is relatively light compared to other r-process elements. And its simple atomic structure creates a few strong and well-known spectral clues. So Watson and his colleagues expanded their analysis to consider it. In doing so, they turned up the clear "fingerprint" of strontium. It emerged in light collected by the Very Large Telescope in Chile within a few days of the neutron-star collision. Seeing strontium in the afterglow wasn’t all that unexpected, says Brian Metzger. He’s an astrophysicist at Columbia University in New York City and not involved in the new work. Strontium, he notes, “does tell us something interesting” about the elements formed during the neutron-star collision.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.
Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.
Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut down.
