With the Tesla Roadster and other plug­in (插入式) electric vehicles hitting the road,demand is growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicago­based company,has now demonstrated a solar­powered recharging point, known as the Solar Plug­In Station,which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.

The Solar Plug­In Station has gone on show in Chicago as part of the city’s bid to host the 2016 Olympic Games. According to Carbon Day Automotive,the Solar Plug­In Station on show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.

These solar­powered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollution­free solar cell, the CO2 emissions are reduced to zero.

“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations,marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar Plug­In Station consists of giant solar panels (电池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack,ready for everyday refueling.

“Without these stations it would be like driving around in a traditional car without the availability of gas stations,” says Scott Emalfarb,CEO at Carbon Day.“The day of true plug­in electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them.”

第二节信息匹配(共5小题;每小题2分,满分10分)

阅读下列应用文及相关信息,并按照要求匹配信息。请在答题卡上将对应题号的相应选项字母涂黑。

以下是一些新闻报道的信息:

[A]. Science magazine published the study about orangutans. The scientists collected evidence from years of observations in six areas on Borneo and Sumatra. The scientists found that the animals demonstrated a total of twenty-four signs of cultural activity. Several actions were demonstrated in some orangutan groups, but not others.

[B]. The Environmental Investigation Agency and Telapak released the report. Telapak is an environmental group based in Indonesia. The Environmental Investigation Agency operates in several countries. The two groups say Indonesia controls ten percent of the world's tropical rainforests.

[C]. Richard Sandor is the chairman of the C-C-X. He praised the companies forming the group for demonstrating leadership. He said they believe that an active way to deal with global warning helps everyone. The group said its members want to reduce costs they may face from future rules on greenhouse gas emissions. Trading credits may help businesses find the most effective methods to reduce pollution. Members also hope to improve their public image on environmental issues.

[D]. Their most detailed effort involved ninety-nine kinds of birds, insects and plants in North America and Europe. They found that the territory where these plants and animals live has moved north by an average of six kilometers every ten years. In Europe, some butterflies now live as much as one hundred kilometers to the north because of changes linked to higher temperatures.

[E]. The new report says many areas experienced unusual weather in two thousand and two. Most of Asia, for example, was warmer than usual. India had unusually high temperatures in April and May. The extremely hot weather caused hundreds of deaths. There also were extremely dry conditions across India. Parts of Africa experienced unusual heavy rains. Yet other areas in Africa had unusual dry weather.

[F]. Hydrogen is the most common element in the universe. Hydrogen is a colorless gas. On Earth, it is present in large amounts in natural gas, coal, plants and water. By weight, hydrogen produces the highest energy levels of any known fuel. When burned in an engine, hydrogen releases no harmful pollution into the environment. When powering a fuel cell, the only waste is water. However, hydrogen is difficult to store. It also burns easily.

请阅读以下与新闻信息,然后匹配与上面新闻相关的报道内容:

46. A severe ocean storm hit South Korea in August. It set a new national record for rainfall. In central Europe, more than one hundred people died in flooding caused by heavy rainfall in September. The flooding also resulted in thousands of millions of dollars in property damage. Yet large parts of North and South America had extremely dry weather.

47. One member of the Chicago Climate Exchange is American Electric Power. It's the biggest owner of electric power producers in the United States. Company officials say they hope their company's membership will demonstrate the ability of the C-C-X to grow.

48. For example, members of some groups make a kissing noise by tightening their mouths and sucking in air. Some groups use leaves to clean themselves or protect their hands from sharp objects. The scientists found that some of the animals use sticks as tools to remove insects from holes in trees. Other orangutans use leaves to crush insects or gather water.

49. Professors Parmesan and Yohe used similar methods to examine one hundred and seventy-two kinds of wildlife. They examined the timing of events in the spring, such as the appearance of flowers and the reproduction of animals. They found that these events happened an average of two days earlier than normal every ten years.

50. They say illegal operations to remove trees are causing large areas of forest to disappear. Environmental Investigation Agency director Dave Currey says the illegal operations are completely out of control.

Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc(硬盘), what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.

Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.

The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.

Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.

The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.

The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.

57. The purpose of the experiment is _____.

A. to combine the computer and the human brain    

B. to enlarge the capacity of human brain

C. to make some stupid dog turn clever          D. to make bear swim

58. Which of the following statements is TRUE?

A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.

B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.

C. The second experiment wasn’t an entire transplant of the memory area.

D. The Idiot was an animal with memory before brain experiment

59. What does the underlined word “success” refer to?

A. The two dogs woke up.

B. They were both good at memorizing.

C. The Idiot grasped all the abilities of Genius.

D. The Genius grasped all the abilities of Idiot.

60. According to the text, we can infer _____.

A. a person can know more after the experiment

B. a bear can swim after being transferred a chip with related useful information

C. a dog can become clever after entire transplant of the memory area

D. it is really good for animals to have been involved in the transplant experiment

(E)

A.Importance of Transport in Trade

B.Birth of Transport-related Industries and Trade

C.Role of Transport in Trade Development

D.Another Means to Develop Trade

E.Higher Living Standard

F.Modern Life Needs Modern Traffics

80.

Transport is one of the aids to trade.By moving goods from places where they are plentiful to places where they are scarce, transport adds to their value.The more easily goods can be brought over the distance that separates producer and consumer, the better for trade.When there were no railways, no good roads, no canals, and only small sailing ships, trade was on a small scale.

81.

The great advances made in transport during the last two hundred years were accompanied by a big increase in trade.Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand, for instance.Quicker transport makes possible mass-production and big business, drawing supplies from, and selling goods to, all parts of the globe.Big factories could not exist without transport to carry the large number of workers they need to and from their homes.Big city stores could not have developed unless customers could travel easily from the suburbs and goods delivered to their homes.Big cities could not survive unless food could be brought from a distance.

82.

Transport also prevents waste.Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns.Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally.Foods which at one time could be obtained only during a part of the year can now be obtained all through the year.Transport has raised the standard of living.

83.

By moving fuel, raw materials, and even power, for example, through electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before.Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another.The cheaper and quicker transport becomes, the longer the distance over which goods can profitably be carried.Countries with poor transport have a lower standard of living.

84.

Commerce requires not only the moving of goods and people but also the carrying of messages and information.Means of communication, like telephones, cables and radio, send information about prices, supplies, and changing conditions in different parts of the world.In this way, advanced communication system also help to develop trade.
