Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Ban University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.

The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.
【小题1】What’s the meaning of “complex” in the second paragraph?
| A．Something that is difficult to understand. |
| B．A group of buildings together in one place. |
| C．A group of things that are connected. |
| D．A mental state that is not normal. |
| A．By fans. | B．Via ceiling vents. |
| C．Through chimneys. | D．Via ceiling vents and through chimneys. |
| A．Skies without clouds. |
| B．Little dampness. |
| C．Daily rapid temperature changes |
| D．Seasonal rapid temperature changes. |
| A．It changes in a certain range with some exception. |
| B．It changes from one extreme to another. |
| C．It remains the same without any exception. |
| D．It is hard to endure. |
| A．The engineering firm of Ove Arup&Partners. |
| B．How air-conditioning works. |
| C．Fans make Eastgate Building’s temperature comfortable. |
| D．How Eastgate Building’s temperature control system works. |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron that is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小题1】A good title for this reading passage is______.
| A．Popeye the Sailor | B．The Truth About Spinach |
| C．A Mistake with Numbers | D．Folic Acid Makes You Strong |
| A．They thought spinach made them strong. |
| B．They thought Popeye was funny. |
| C．Spinach had a lot of iron. |
| D．People liked folic acid. |
| A．made Popeye strong |
| B．was a green vegetable |
| C．had less iron than other green vegetables |
| D．had more iron than other green vegetables |
| A．iron | B．folic acid | C．spinach | D．exercise |

We probably all know people, either at work or in our personal lives, who are really good listeners. No matter what kind of situation we’re in, they always seem to know just what to say and how to say it so that we’re not offended(被冒犯) or upset. We probably also know people who are masters at managing their emotions(情绪). They don’t get angry in stressful situations. Instead, they have the ability to calmly look at a problem and find a solution. They take criticism(批评) well, and they know when to use it to improve their performance.
People like these who have a high degree of emotional intelligence, or EI(情商). They know themselves very well, and they’re also able to sense the emotional needs of others.
As more and more people accept that emotional intelligence is just as important to professional success as technical(专业的) ability, companies are increasingly using EI when they hire and promote(提拔) someone. For example, one large cosmetics (化妆品) company recently changed their hiring process for salespeople to choose candidates(被选的人) based on emotional intelligence. The result? Salespeople hired with the new system have sold, on average, $91,000 more than salespeople selected under the old system.
Emotional intelligence is the ability to recognize your emotions, understand what they are telling you, and realize how your emotions affect people around you. Emotional intelligence also involves your perception (洞察力) of others: when you understand how they feel, this allows you to manage relationships more effectively.
People with high emotional intelligence are usually successful in most things they do. Why? Because they are the ones that others want on their team. When people with high EI send an email, it get answered. When they need help, they get it. Because they make others feel good, they go through life much more easily than people who are easily angered or upset.
The good news is that emotional intelligence can be taught and developed. Many books and tests are available to help you determine your current EI, and identify where you may need to do some work.
【小题1】According to the passage, we’re all probably impressed by people who _____.
| A．are ready to help others |
| B．are very successful in their lives |
| C．have high emotional intelligence |
| D．know how to control their temper |
| A．stress the importance of emotional intelligence |
| B．speak highly of its new salespeople |
| C．show its effective hiring system |
| D．explain what improvements it has made |
| A．your emotions | B．people around you |
| C．effective relationships | D．your opinions of others |
| A．They are usually good speakers. |
| B．They are born to be sensitive and intelligent. |
| C．They don’t get angry in any situation. |
| D．They can understand others’ feelings well. |
| A．What emotional intelligence is. |
| B．How emotional intelligence can be improved. |
| C．Many books on emotional intelligence. |

One reaction to all the concern about tropical deforestation（毁林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
【小题1】The underlined word "synthetics" probably means_________.
| A．natural rubber | B．tropical materials |
| C．man-made material | D．commercial rubber |
| A．The forests are losing their function in turning carbon dioxide into oxygen. |
| B．Many of our daily uses are related to the tropical forests. |
| C．Tropical plants can be used to make industrial products. |
| D．High carbon dioxide levels will make the earth warmer. |
| A．puzzling | B．cold | C．supporting | D．opposed |
| A．Tropical Forests | B．The Value of Tropical Forests |
| C．Tropical Forests and Our Life | D．The Greenhouse Effects |

It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（规模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.
【小题1】Which of the following is a reason for the cutting and burning of forests?
| A．To build houses for more population. | B．To have land for agriculture. |
| C．To export trees to other countries. | D．To build industrial plants. |
| A．man’s research activities | B．the greenhouse effect |
| C．the ultraviolent | D．harmful chemicals |
| A．They don’t want to put their lives in danger. |
| B．They just don’t know how to solve the problem. |
| C．They haven’t realized the seriousness of the problem. |
| D．They don’t want to break their international commitment. |
| A．Hopeful. | B．Unconcerned | C．Doubtful | D．Objective |

Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said. “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.” “Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen: “ENTER NAMES
VOYAGER 1:…
VOYAGER 2:…”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED (自动回收程序已启动).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒) , until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION (目的地)：MARS. RETRIEVE DATE: 2025.”

It is not unusual for people to speak two or three languages; they’re known as bilinguals or trilinguals. Speakers of more than three languages are known as polyglots. And when we refer to people who speak many languages, perhaps a dozen or more, we use the term hyper-polyglot.
The most famous hyper-polyglot was Giuseppe Mezzofanti, a 19th century Italian cardinal, who was said to speak 72 languages. This claim sounds absurd. If you assume each language had 20,000 words, Mezzofanti would have to learn a word a minute, six hours a day, for eleven years—an impossible task. But Mezzofanti was tested by critics, and they were all impressed.
Did Mezzofanti have an extraordinary brain? Or are hyper-polyglots just ordinary people with ordinary brains who manage to do something extraordinary through hard work?
U.S. linguist Stephen Drashen believes that outstanding language learners just work harder at it and then they acquire unusually strong language ability. As an example, he mentions a Hungarian woman who worked as an interpreter during the 20th century. When she was 86, she could speak 16 languages and was still working on learning new languages. She said she learned them mostly on her own, reading fiction or working through dictionaries or textbooks.
Some researchers argue to the contrary. They believe that there is such a thing as a talent for learning languages. In the 1930s, a German scientist examined parts of the preserved brain of a hyper-polyglot named Emil Krebs, who could speak 60 languages fluently. The scientist found that the area of Krebs’s brain called Broca’s area, which is associated with language, looked different from the Broca’s area in the brains of men who speak only one language. However, we still don’t know if Krebs was born with a brain ready to learn dozens of languages or if his brain adapted to the demands he put on it.
Although it is still not clear whether the ability to learn many languages is in born, there’s no doubt that just about all of us can acquire skills in a second, third, or even fourth language by putting our mind to it.
【小题1】What does the underlined sentence imply?
| A．Mezzofanti could remember 360 words a day. |
| B．Mezzofanti had a special way to learn languages. |
| C．Mezzofanti’s achievement was ridiculous. |
| D．Mezzofanti language ability was astonishing. |
| A．good memory | B．unique brain | C．hard work | D．learning methods |
| A．had an unusual brain |
| B．was born with great talent |
| C．had worked hard at languages |
| D．expected too much of himself |
| A．it is not hard to learn foreign languages |
| B．hard work plays a part in language learning |
| C．there is no such thing as a talent for languages |
| D．hyper-polyglots have an inborn talent for language |

Half of the world’s population is affected by Asian monsoons（季风）, but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.
Every year, damp air masses，known as monsoon，produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.
According to Edward Cook , a weather expert at Columbia University in New York., the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places.
Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.
Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.
“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”
【小题1】What’s the passage mainly about？
| A．The effects of Asian monsoons. |
| B．The necessity of weather forecast. |
| C．The achievements of Edward cook. |
| D．A breakthrough in monsoon prediction. |
| A．it is hard to keep long-term climate records. |

| C．they influence many nations. |
| D．there is heavy rainfall in Asia. |
| A．Long and detailed climate records can offer useful information for monsoon research. |
| B．The Monsoon Asia Drought Atlas has a monsoon record for about 1,300 years. |
| C．The trees affected by monsoon grow fast if the monsoon is weak. |
| D．The rainfall might be low although the monsoon is strong in monsoon-affected areas. |
| A．determine the regional climate. |
| B．have a great influence on the regional climate. |
| C．offer people information about the regional climate. |
