填空题 Scientists are looking at ways to {{U}} {{U}} 1 {{/U}} {{/U}}the global temperature by removing greenhouse gases from the air. Carbon dioxide has a {{U}} {{U}} 2 {{/U}} {{/U}}effect on the Earth's temperature. Since the industrial revolution, humans have been burning {{U}} {{U}} 3 {{/U}} {{/U}}amounts of fossil fuels, releasing large amounts of carbon dioxide. The gas is changing the climate, warming the {{U}} {{U}} 4 {{/U}} {{/U}}for plants and animals and raising sea {{U}} {{U}} 5 {{/U}} {{/U}}. Even if we stopped burning fossil fuels today, there is enough carbon dioxide in the atmosphere. Hence, we have the idea of finding ways of {{U}} {{U}} 6 {{/U}} {{/U}}carbon dioxide. In recent years there have been {{U}} {{U}} 7 {{/U}} {{/U}}to remove the carbon dioxide from its {{U}} {{U}} 8 {{/U}} {{/U}}in power plants. {{U}} {{U}} 9 {{/U}} {{/U}}have been fitted to the {{U}} {{U}} 10 {{/U}} {{/U}}, so the carbon dioxide produced during fuel burning can be removed from the {{U}} {{U}} 11 {{/U}} {{/U}}emissions. The carbon dioxide can be cooled and pumped for {{U}} {{U}} 12 {{/U}} {{/U}}in underground rock chambers, which is a useful way of preventing carbon dioxide from entering the {{U}} {{U}} 13 {{/U}} {{/U}}. But what about the {{U}} {{U}} 14 {{/U}} {{/U}}that is already out there? The problem with removing carbon dioxide from the atmosphere is that it's {{U}} {{U}} 15 {{/U}} {{/U}}at such a {{U}} {{U}} 16 {{/U}} {{/U}}concentration. Removing the gas takes lots of energy. Though it is expensive, it's {{U}} {{U}} 17 {{/U}} {{/U}}. Extracting the {{U}} {{U}} 18 {{/U}} {{/U}}of carbon dioxide in the atmosphere would require enormous volumes of {{U}} {{U}} 19 {{/U}} {{/U}}to be processed. Therefore, most scientists have {{U}} {{U}} 20 {{/U}} {{/U}}at the idea.

填空题 Tammet is a genius of memory. He broke the European record for recalling π, the {{U}} {{U}} 1 {{/U}} {{/U}}, to the furthest decimal point. He found it easy, because he didn't even have to "think". To him, π isn't an {{U}} {{U}} 2 {{/U}} {{/U}}; it's a visual story, a film projected in front of his eyes. He {{U}} {{U}} 3 {{/U}} {{/U}}and, last year, spent five hours recalling it in front of an adjudicator. He wanted to prove a point. "I memorized π to {{U}} {{U}} 4 {{/U}} {{/U}}decimal places, and I am technically disabled. I just wanted to show people that disability {{U}} {{U}} 5 {{/U}} {{/U}}."

He lives on the Kent coast, but {{U}} {{U}} 7 {{/U}} {{/U}}— there are too many pebbles to count. The thought of a mathematical problem {{U}} {{U}} 8 {{/U}} {{/U}}makes him feel uncomfortable. Trips to the supermarket are always a chore. "There's {{U}} {{U}} 9 {{/U}} {{/U}}. I have to look at every shape and texture. Every price, and every arrangement: {{U}} {{U}} 10 {{/U}} {{/U}}. So instead of thinking, 'What cheese do I want this week?', I'm just {{U}} {{U}} 11 {{/U}} {{/U}}." Tammet has never been able to {{U}} {{U}} 12 {{/U}} {{/U}}. It would be too difficult to fit around his daily routine. For instance, he has to drink his cups of tea {{U}} {{U}} 13 {{/U}} {{/U}}every day. Things have to happen in the same order, he always brushes his teeth before he {{U}} {{U}} 14 {{/U}} {{/U}}. "I have tried to be more flexible, but I always end up feeling more uncomfortable. Retaining {{U}} {{U}} 15 {{/U}} {{/U}}is really important. I like to do things in my own time, and {{U}} {{U}} 16 {{/U}} {{/U}}, so an office with {{U}} {{U}} 17 {{/U}} {{/U}}just wouldn't work." Instead, he has set up a business on his own, at home, {{U}} {{U}} 18 {{/U}} {{/U}}in language learning, numeracy and literacy for private clients.

填空题I"ve always known my kids use 21 gear a lot. But my cellphone bill last month really grabbed my 22 . My son had racked up nearly 23 , and had sent nearly as many. That means he was having more than 60 24 via text message every day. 25 , he was out of school for the summer and communicating more with friends 26 . Nevertheless, I had to wonder how he found time to hold down a summer job and complete a college course in between all that 27 with his thumb. I was even 28 to learn that my son is normal. "Teenagers with cellphones each send and receive 29 a month on average", Nielsen Mobile says. Some experts lament that all that keyboard jabber is making our kids stupid unable to read nonverbal cues such as 30 , gestures, posture and other silent signals of mood and attitude. Unlike phones, text messaging doesn"t even allow transmission of tone of 31 . States are cracking down on drivers who text, 32 . My son doesn"t text while driving, and we have discussed the dangers. Beyond that, though, I"m not sure I see 33 critics of this trend. I"ve posted before on how I initially tried to curb my kids" texting. But over time, I have seen my son suffer no apparent 34 , and he reaps a big benefit, of easy, continuing contact with many friends. Also, the time he spends texting replaces the hours teens used to spend on the phone: 35 dislike talking on the phone, and say they really don"t need to do so to 36 and family. Does texting make kids stupid? I don"t think so. It may make them annoying, when they try to text and talk to you 37 . And it may make them distracted, when buzzing text messages interrupt efforts to noodle out a calculus problem or finish reading for school. But I don"t see texting 38 teens" ability to communicate. My son is as attuned to nonverbal cues as any older members of our family. If anything, I have found him 39 and easier to communicate with from afar, because he is constantly available via 40 and responds with a faithfulness and speed that any mother would find reassuring.

填空题 Today I want to discuss problems of{{U}} (1) {{/U}}and three possible polices which could stop{{U}} (2) {{/U}}urbanization in developing countries. Certain urban problems are{{U}} (3) {{/U}}to both developed and developing countries, for example, poor housing,{{U}} (4) {{/U}}, traffic congestion and pollution.

The provision of this infrastructure is the urbanization process itself. There are five main{{U}} (7) {{/U}}of this uncontrolled urbanization: Firstly, people{{U}} (8) {{/U}}from the country to city because they see the city as a more{{U}} (9) {{/U}}place to live.

In this way farmers would be more{{U}} (17) {{/U}}to stay on the land. Secondly, to improve the supply of social services in the{{U}} (18) {{/U}}areas, particularly in the field of health and education.

填空题 The term home schooling or home tuition, as it is called in England, means educating children at home or in places other than a{{U}} (1) {{/U}}such as a public or private school. There are many reasons why parents choose home schooling for their children. Some parents are{{U}} (2) {{/U}}the quality of education in public schools. Others do not want their children to have to worry about{{U}} (3) {{/U}}, or social pressure from friends. These parents fear this type of pressure will lead to{{U}} (4) {{/U}}such as smoking, drinking alcohol and taking drugs. {{U}}(5) {{/U}}from other students is another concern. In 1996, it was estimated that between 120,000 and{{U}} (6) {{/U}}children are being home schooled in the U.S. Professor Jane describes parents who teach their children at home as either ideologues or pedagogues. Ideologues tend to view home school as opportunities to{{U}} (7) {{/U}}using pre-determined curricula, textbooks and{{U}} (8) {{/U}}. Pedagogues tend to place the learner central to everything else that transpires in the home. Whatever the forms, there are however some basic keys to creating a successful environment for home schooling: Provide an opportunity for children to{{U}} (9) {{/U}}other children close to their age. With today's technology, {{U}}(10) {{/U}}as many types of instruction methods as possible. These methods may include{{U}} (11) {{/U}}, interactive satellite broadcasts or electronic networks among schools. By then, the teacher will{{U}} (12) {{/U}}as adviser, instead of imparting knowledge, they would (13) the available information. The basic skills such as reading, writing and mathematics should not be overlooked. These may be{{U}} (14) {{/U}}when possible. Many of these students will at some point enter the public system.

The debate over home schooling versus public schooling is still prevailing and many questions have{{U}} (17) {{/U}}. Will this marginal model of schooling replace traditional schools and{{U}} (18) {{/U}}? How are home schoolers assessed? Are home schooling children{{U}} (19) {{/U}}the social benefits of being in a large classroom? As with any debatable issue, the answers to these questions are neither{{U}} (20) {{/U}}.

填空题 Some may ask the following question: Was it envisioned for the euro to eventually become {{U}} {{U}} 1 {{/U}} {{/U}}that it could compete with the dollar {{U}} {{U}} 2 {{/U}} {{/U}}? Or was that a dream then and {{U}} {{U}} 3 {{/U}} {{/U}}? I think it was an attainable dream, and it is becoming actually, in some ways, {{U}} {{U}} 4 {{/U}} {{/U}}. Why? Well, the dream to give credit where credit is due was not only advocated {{U}} {{U}} 5 {{/U}} {{/U}}but by some American economists, including our Institute's director, Fred Bergsten. He was {{U}} {{U}} 6 {{/U}} {{/U}}with that. Richard Portes, who teaches at {{U}} {{U}} 7 {{/U}} {{/U}}, also was way out in the front with that. And they were {{U}} {{U}} 8 {{/U}} {{/U}}of people like Martin Feldstein and others in London and the United States who {{U}} {{U}} 9 {{/U}} {{/U}}the euro. At face value, the euro area is {{U}} {{U}} 10 {{/U}} {{/U}}as the United States, roughly speaking. The euro area does have very large and {{U}} {{U}} 11 {{/U}} {{/U}}, although if you look in more detail, there are still some things there that {{U}} {{U}} 12 {{/U}} {{/U}}the United States. And the euro area has delivered price stability. They have a {{U}} {{U}} 13 {{/U}} {{/U}}pretty consistently. So you put those three things together. On paper it looks like the euro should be at least {{U}} {{U}} 14 {{/U}} {{/U}}to the dollar in investors' portfolios, in government reserve holdings, in how much you {{U}} {{U}} 15 {{/U}} {{/U}}or planes or things like that. But what {{U}} {{U}} 16 {{/U}} {{/U}}in this book is the fact that if you look under the hood a bit, there is {{U}} {{U}} 17 {{/U}} {{/U}}between what you would expect just based on size and how much the euro is used. So there's an awful lot of {{U}} {{U}} 18 {{/U}} {{/U}}, not in euros, even between countries that are not dollar countries. There are {{U}} {{U}} 19 {{/U}} {{/U}}that come to the United States, and the depth of European assets and financial flows is {{U}} {{U}} 20 {{/U}} {{/U}}.

填空题{{B}}Part A Note-taking And Gap-filling{{/B}} Directions: In this part of the test you will hear a short tally. You will hear the talk ONLY ONCE. While listening to the talk, you may take notes on the important points so that you can have enough information to complete a gap-filling task on a separate ANSWER BOOKLET. You will not get your ANSWER BOOKLET until after you have listened to the talk. No {{U}}(1) {{/U}} way exists to explain how to form a good idea. You think about a problem until you are tired, forget it, maybe sleep on it, and then {{U}}(2) {{/U}}! When you're not thinking about it, suddenly the answer arrives as a gift from the gods. Of course, all ideas don't occur like that but so many do, particularly the most important ones. They burst into the mind, glowing with the heat of {{U}}(3) {{/U}}. How they do it is a {{U}}(4) {{/U}}, but they must come from somewhere. Let's assume they come from the "{{U}} (5) {{/U}}". This is reasonable, for psychologists use this term to describe {{U}}(6) {{/U}} processes, which are unknown to the {{U}}(7) {{/U}} Creative thought depends on what was unknown becoming known. All of us have {{U}}(8) {{/U}} this sudden arrival of new idea, but it is easiest to examine it in the great creative {{U}}(9) {{/U}}. One can draw examples from genius in any field. All truly creative activities depend in some degree on these {{U}}(10) {{/U}} from the unconscious, and the more highly {{U}}(11) {{/U}} the person, the shaper and more {{U}}(12) {{/U}} the signals become. In the example of Richard Wagner {{U}}(13) {{/U}} the opening to "Rhinegold", the conscious mind at the moment of creation knew something of the actual processes by which the {{U}}(14) {{/U}} was found. As a {{U}}(15) {{/U}} , Henri Poincare's finding of the Fuchsian functions make us see the conscious mind {{U}}(16) {{/U}} the new combinations being formed in the unconscious, while the Wagner story shows the sudden {{U}}(17) {{/U}} of a new concept into consciousness. Wagner's and Poincare's experiences are {{U}}(18) {{/U}} of countless others in every field of culture. The unconscious is certainly the source of {{U}}(19) {{/U}} activity. But in creative thought the unconscious is responsible for the production of new organized forms from relatively {{U}}(20) {{/U}} elements.
