The Antarctica is actually a desert. It is the only continent on the earth without a river or a lake.
The Antarctica is all ice all year round. The warmest temperature ever recorded there is zero, at the South Pole. Explorers used to think that a place so cold would have a heavy snowfall. But less than ten inches of snow falls each year. That is less than half an inch of water. Ten times that much moisture (水份) falls in parts of the Sahara.
The little snow that falls in Antarctica never melts. It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about eighty feet deep it is turned to ice by the weight of snow above it .
Antarctica is called a desert because it_______.
| A．is sandy. |
| B．has the same temperature as a desert. |
| C．has little moisture and no lakes or rivers. |
| D．there are no people there. |
Antarctica has_______.
| A．ten times as much moisture as the Sahara. |
| B．the same amount of moisture as the Sahara. |
| C．about one—tenth of the moisture of the Sahara. |
| D．none of the above. |
The snow in Antarctica is very deep because it_______.
A. never stops falling. B. piles up year after year.
C. never melts. D. both B and C.
The snow turns to ice when______.
| A．it gets wet. |
| B．the next snowfall comes. |
| C．the temperature gets colder. |
| D．the snow above it is heavy enough. |

In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.
Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.
Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.
Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.
The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying reusable products and recycling.
In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?
Governments’ incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?
From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.By mentioning the Swiss study, the author intends to tell us that _________ .
| A．the weight of e-goods is rather small |
| B．E-waste deserves to be made good use of |
| C．natural minerals contain more precious metals |
| D．the percentage of precious metals is heavy in e-waste |
The responsibility of e-waste treatment should be extended _________ .
| A．from producers to governments |
| B．from governments to producers |
| C．from individuals to distributors |
| D．from distributors to governments |
What does the passage mainly talk about?
| A．The increase in e-waste. |
| B．The creation of e-waste. |
| C．The seriousness of e-waste. |
| D．The management of e-waste. |

Life in the Clear
Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”
And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.
The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.
But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.
To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.
Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .
Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.According to Paragraph 1, transparent animals_______.
| A．stay in groups | B．can be easily damaged |
| C．appear only in deep ocean | D．are beautiful creatures |
The underlined word “dead” in Paragraph 3 means__________.
| A．silently | B．gradually |
| C．regularly | D．completely |
One way for an animal to become transparent is to ________.
| A．change the direction of light travel |
| B．gather materials to scatter light. |
| C．avoid the absorption of light |
| D．grow bigger to stop light. |
The last paragraph tells us that larger transparent animals________.
| A．move more slowly in deep water |
| B．stay see-through even after death |
| C．produce more tissues for their survival |
| D．take effective action to reduce light spreading |
D
The oddness of life in space never quite goes away. Here are some examples.
First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. "I'm an inside guy," Mike Hopkins says, who returned from a six-month tour on the International Space Station. "I like to be wrapped up."
On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.
Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,"Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying-that's why some people feel sick." Within a couple days -truly terrible days for some -astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.
Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.

One of the executives gathered at the Aspen Institute for a day-long leadership workshop using the works of Shakespeare was discussing the role of Brutus in the death of Julius Caesar. “Brutus was not an honorable man,” he said. “He was a traitor（叛徒）. And he murdered someone in cold blood.” The agreement was that Brutus had acted with cruelty when other options were available to him. He made a bad decision, they said—at least as it was presented by Shakespeare—to take the lead in murdering Julius Caesar. And though one of the executives acknowledged that Brutus had the good of the republic in mind, Caesar was nevertheless his superior. “You have to endeavor,” the executives said, “our policy is to obey the chain of command.”
During the last few years, business executives and book writers looking for a new way to advise corporate America have been exploiting Shakespeare’s wisdom for profitable ends. None more so than husband and wife team Kenneth and Carol Adelman, well-known advisers to the White House, who started up a training company called “Movers and Shakespeares”. They are amateur Shakespeare scholars and Shakespeare lovers, and they have combined their passion and their high level contacts into a management training business. They conduct between 30 and 40 workshops annually, focusing on half a dozen different plays, mostly for corporations, but also for government agencies.
The workshops all take the same form, focusing on a single play as a kind of case study, and using individual scenes as specific lessons. In Julius Caesar , sly provocation（狡诈的挑唆） of Brutus to take up arms against the what was a basis for a discussion of methods of team building and grass roots organism.
Although neither of the Adelmans is academically trained in literature, the programmes, contain plenty of Shakespeare tradition and background. Their workshop on Henry V, for example, includes a helpful explanation of Henry’s winning strategy at the Battle of Agincourt. But they do come to the text with a few biases (偏向): their reading of Henry V minimizes his misuse of power. Instead, they emphasize the story of the youth who seizes opportunity and becomes a masterful leader. And at the workshop on Caesar, Mr. Adelmans had little good to say about Brutus, saying “the noblest Roman of them all” couldn’t make his mind up about things.
Many of the participants pointed to very specific elements in the play that they felt related Caesar’s pride, which led to his murder, and Brutus’s mistakes in leading the after the murder, they said, raise vital questions for anyone serving as a business when and how do you resist the boss?According to paragraph 1, what did all the executives think of Brutus?
| A．Cruel. | B．Superior. |

According to the passage, the Adelmans set up “Movers and Shakespeares” to ________.
| A．help executives to understand Shakespeare’s plays better |
| B．give advice on leadership by analyzing Shakespeare’s plays |
| C．provide case studies of Shakespeare’s plays in literature workshops |
| D．guide government agencies to follow the characters in Shakespeare’s plays. |
Why do the Adelmans conduct a workshop on Henry V?
| A．To highlight the importance of catching opportunities. |
| B．To encourage masterful leaders to plan strategies to win. |
| C．To illustrate the harm of prejudices in management. |
| D．To warn executives against power misuse. |
It can be inferred from the passage that ____.
| A．the Adelmans’ programme proves biased as the roles of characters are maximized. |
| B．executives feel bored with too many specific elements of Shakespeare’s plays. |
| C．the Adelmans will make more profits if they are professional scholars. |
| D．Shakespeare has played an important role in the management field. |
The best title for the passage is _____.
| A．Shakespeare’s plays: Executives reconsider corporate culture |
| B．Shakespeare’s plays: An essential key to business success |
| C．Shakespeare’s plays: a lesson for business motivation |
| D．Shakespeare’s plays: Dramatic training brings dramatic results |

Look to many of history’s cultural symbols, and there you’ll find an ancestor of Frosty, the snowman in the movie Frozen. It appeared on some of the first postcards, starred in some of the earliest silent movies, and was the subject of a couple of the earliest photos, dating all the way back to the 1800s. I discovered even more about one of humanity’s earliest forms of life art during several years of research around the world.
For example, snowmen were a phenomenon in the Middle Ages, built with great skill and thought. At a time of limited means of expression, snow was like free art supplies dropped from the sky. It was a popular activity for couples to leisurely walk through town to view the temporary works of chilly art. Some were created by famous artists, including a 19-year-old Michelangelo, who in 1494 was appointed by the ruler of Florence, Italy, to build a snowman in his mansion’s courtyard.
The Miracle of 1511 took place during six freezing works called the Winter of Death. The city of Brussels was covered in snowmen—an impressive scene that told stories on every street corner. Some were political in nature, criticizing the church and government. Some were a reflection of people’s imagination. For the people of Brussels, this was a defining moment of defining freedom. At least until spring arrived, by which time they were dealing with damaging floods.
If you fear the heyday of the snowman has passed, don’t worry: I’ve learned that some explosive snowman history is still being made today. Every year since 1818, the people of Zurich, Switzerland, celebrate the beginning of spring by blowing up a snowman. On the third Monday of April, the holiday Sechselauten is kicked off when a cotton snowman called the Boogg is stuffed with explosive and paraded through town by bakers and other tradesmen who throw bread to the crowds. The parade ends with the Boogg being placed on a 40-foot pile of firewood. After the bells of the Church of St. Peter have rung six times, representing the passing of winter, the pile is lit. When the snowman explodes, winter is considered officially over—the quicker it is burnt down, the longer summer is said to be.According to the passage, why did snowmen become a phenomenon in the Middle Ages?
| A．People thought of snow as holy art supplies. |
| B．People longed to see masterpieces of snow. |
| C．Building snowmen was a way for people to express themselves. |
| D．Building snowmen helped people develop their skill and thought. |
“The heyday of the snowman” （paragraph 4） means the time when___________.
| A．snowmen were made mainly by artists |
| B．snowmen enjoyed great popularity |
| C．snowmen were politically criticized |
| D．snowmen caused damaging floods |
In Zurich, the blowing up of the Boogg symbolizes__________________.
| A．the start of the parade |
| B．the coming of a longer summer |
| C．the passing of the winter |
| D．the success of tradesmen |
What can be concluded about snowmen from the passage?
| A．They were appreciated in history |
| B．They have lost their value |
| C．They were related to movies |
| D．They vary in shape and size |
