2 . Each week, the BBC Autos editors select their favourite transport-related news stories, features and videos from around the web. This week, we noticed a trend toward offering creative solutions to global transportation problems.     1    .

Carry on without your carry-on

In an effort to save money and increase customer spending, United Airlines will restrict some passengers’ access to overhead compartments. The Huffington Post reports that United will be the first US airline to limit “basic economy” flyers to a single free carry-on bag that can fit under a seat.     2    . In addition, customers buying these low-fare tickets will be unable to accrue airline miles and will be randomly assigned seating the day of the flight.

    3    .   As BBC Autos reported back in October, airlines are struggling with reducing cargo weight. Because heavier bags — and heavier passengers — result in significantly higher fuel bills, airlines such as Samoa Air have implemented a “fat tax” that means overweight passengers have to pay more for a ticket.

Grandad’s Coke pool rust-removal stunt goes wrong

Not only are fizzy drinks(起泡饮料) capable of rotting teeth, they can also remove rust(锈). One Latvian grandfather decided to put cola to the ultimate rust-removal test by submerging his car in a pool of Coca-Cola. In a video posted online, the unnamed daredevil grandad fills a lined pit with 6,000 two-litre bottles of Coke. He then settles into the driver’s seat and speeds into the hole, smashing the front of his red Audi. Whether or not the rust was removed is unknown, but the Daily Mail contends that “    4    ”.

A.Improvement in the amount of rust on the car was far less than the damage to the vehicle.
B.The problems have stirred up heated discussion on the Internet.
C.Some of the suggestions are innovative and intelligent, but others are likely to make travelers     feel funny.
D.Coca-Cola is already a food giant, which attracts children and adults alike around the world.
E.In other words, starting next year, those who purchase the cheapest fares will not only be allowed one personal item that fits under the seat in front of them.
F.United’s move to limit carry-on bags and charge more for flying perks (飞行特权) isn’t a new concept.

3 . In Japan, where career opportunities for women are few, where divorce can mean a life of hardship, and where most female names are still formed using a word for child, a woman’s independence has always come at a steep price.

Notions of women’s liberation have never taken root among Japanese women. But with inadequate open conflict, the push for separate burials is quietly becoming one of the country’s fastest growing social trends. In a recent survey by the TBS television network, 20 percent of the women who responded said they hoped to be buried separately from their husbands.

The funerary revolt comes as women here annoy at Japan’s slow pace in providing greater equality between the sexes. The law, for example, still makes it almost impossible for a woman to use her maiden name after marriage. Meanwhile, divorce rates are low by Western standards, because achieving financial independence or even obtaining a credit card in one’s own name is an insurmountable obstacle for many divorced women. Until recently, society enforced restrictions on women even in death. Under Japan’s complex burial customs, divorced or unmarried women were traditionally unwelcome in most graveyards, where plots (小块土地) are still passed down through the husband’s family and descendants must provide maintenance for burial sites or lose them.

“The woman who wanted to be buried alone couldn’t find a graveyard until about 10 years ago,” said Haruyo Inoue, a sociologist of death and burial at Japan University. She said that graveyards which did not require descendants to maintain, in order to accommodate women, began appearing in around 1990. Today, she said that there are close to 400 of these cemeteries in Japan. That is just one sign of stirring among Japanese women, who are also pressing for the first time to change the law to be able to use their maiden names after marriage.

Although credit goes beyond any individual, many women cite Junko Mastubara, a popular writer on women’s issues, with igniting the trend to separate sex burials. Starting three years ago, Ms. Matsubara has built an association of nearly 600 women — some divorced, some unhappily married, and some determinedly single — who plan to share a common plot curbed out of an ordinary cemetery in the western suburb of Chofu.

1. What is the passage mainly concerned with?
A.How to change Japan’s complex burial customs.
B.Japanese women’s efforts to win sex equality.
C.Social and governmental obligation in eliminating sex inequality.
D.How Japanese laws prevent Japanese women from being buried alone.
2. From the fact that divorce can mean a life of hardship for Japanese women, we can infer that ________.
A.many Japanese women have a low social status
B.it’s an out-dated custom for Japanese women to be housewives
C.many Japanese women have a bad relationship with their husbands
D.many Japanese women live together with their husbands in perfect harmony
3. Which of the following statements about the funeral revolt in Japan is NOT true?
A.More and more Japanese women prefer to be buried separately from their husbands.
B.Japan’s complex burial customs make it more difficult for Japanese women to be buried separately.
C.More and more Japanese women resort to divorce to win the victory of funeral revolt.
D.It comes as the result of Japanese women’s dissatisfaction with Japan’s slow pace in providing greater sex equality.
4. The meaning of the word “ignite” in the last paragraph is ________.
A.to initiateB.to reverse
C.to suggestD.to strengthen

4 . Chimpanzee culture refers to groups' differing behavioral traditions, which are passed on by learning and imitation rather than genes. For example, some chimps in Uganda have learned to use some plants to soak up water, which they can then drink. Those elsewhere don’t do this.

In 2002, Carel van Schaik at the University of Zurich in Switzerland suggested that human interference could destroy this cultural diversity. Now, a decade-long study has found strong evidence that van Schaik was right. A team co-led by Hjalmar Kühl at the German Centre for Integrative Biodiversity Research in Leipzig, Germany tracked 31 cultural behaviors, such as using tree branches to catch termites, a species of ant, in 144 chimpanzee communities across Africa.

The researchers used camera traps to record behaviors, looked for the remains of tools and studied faeces (排泄物) to see if the chimps had eaten things like termites that can be obtained only by using tools.

The team then placed the different communities on a map and overlaid a measure of human disturbance, which combined factors like the density of human population and the amount of infrastructure (基础建设).

In areas with a greater human footprint, the chimps were found to have fewer cultural behaviors. Each behaviour was 88 per cent less likely to occur in these human-dominated landscapes.

“In those places, we find the chimpanzees have suffered a loss in behavioral or cultural diversity,” says study co-leader Ammie Kalan at the Max Planck Institute for Evolutionary Anthropology in Leipzig.

It is thought that the loss of culture comes from older chimps being killed and there being less interaction between groups, so that if one group dies out, their ideas die with them.

“It is a discouraging finding,” says Jill Pruetz ar Texas State University. “Losing some of the behaviors poses a real risk to the chimps because if they stop fishing for termites or cracking nuts, they can no longer access those foods.”

1. According to the passage, which of the following is a feature of chimpanzee culture?
A.More than one group shares certain kinds of behaviour.
B.The behaviors spread through cross-group imitation.
C.Young chimpanzees learn the behaviors from older ones.
D.The behavioral traditions disappear with certain genes.
2. The word “interference” in paragraph 2 is closest in meaning to ________.
A.interaction
B.interval
C.invasion
D.investment
3. What did the study by Hjalmar Kühl and Leipzig confirm?
A.Chimpanzee communities are decreasing in number.
B.Humans are to blame for the loss of chimpanzee culture.
C.Human-dominated landscapes have been increasing in size.
D.Chimpanzee are good at hunting for food with certain tools.
4. According to Jill Pruetz why does losing some behaviors put chimpanzee at risk?
A.They may have fewer things to feed on.
B.The older ones are more likely to be killed.
C.There will be less interaction between them.
D.They can no longer live in traditional ways.

5 . 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 understand,” 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 to 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, for example, Cassius’s sly provocation(狡诈的挑唆) of Brutus to take up arms against Caesar was a basis for a discussion of methods of team building and grass roots organizing.

Although neither of the Adelmans is academically trained in literature, the programs 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 to be related. Caesar’s pride, which led to his murder, and Brutus’s mistakes in leading the traitors after the murder, they said, raise vital questions for anyone serving in a business: when and how do you resist the boss?

1. 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.
2. It can be inferred from the passage that ________.
A.the Adelmans’ program 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.
3. 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.

6 . Culture Insider: Chopsticks

Chopsticks, or kuaizi in Chinese, are a pair of small equal-length tapered sticks, usually made of wood, used for eating Asian food. It is believed that the first chopsticks were developed over 5,000 years ago in China. The earliest evidence of a pair of chopsticks made out of bronze was excavated from the Ruins of Yin near Anyang, Henan province.

Chopsticks play an important role in Chinese food culture.    1    They are round on the eating end which symbolizes heaven, and the other end is square which symbolizes earth. This is because maintaining an adequate food supply is the greatest concern between heaven and earth.

Chopsticks are so frequently used in daily life that they have become more than a kind of tableware and have fostered a set of etiquette and customs of their own.     2    While the principles of chopstick etiquette are similar in many of these places, the finer points may differ from region to region, and there is no single standard for the use of chopsticks. Generally, chopsticks are not used to make noise or to draw attention, or to gesticulate.

    3    For example, you can buy a pair of exquisite chopsticks as a gift for your friends and relatives. In Chinese, Chopsticks' reads 'kuaizi', which means to have sons soon, so a newly-married couple will be very happy to accept chopsticks as their wedding gift. Skillful craftsmen paint beautiful scenery on chopsticks to make them like fine artwork. Many people love to collect these elegant utensils.

It has been said that using chopsticks improves one's memory, increases finger dexterity and can be useful in learning and improving skills such as Chinese character printing and brush painting. Many Asian superstitions revolve around chopsticks as well. For example, if you find an uneven pair of chopsticks at your table setting, it is believed that you will miss the next train, boat or plane you are trying to catch.     4    .

A.Without chopsticks, you can't even say you are enjoying Chinese food.
B.Chinese chopsticks are usually 9 to 10 inches long and rectangular with a blunt end.
C.Also, dropping your chopsticks is a sign of bad luck.
D.Today, chopsticks serve many functions besides as table ware.
E.It is important to note chopsticks are used in many different parts of the world, in many different cultures.
F.These chopsticks are to be returned to the dishes after one has served himself or herself.

7 . To live in the United States today is to gain an appreciation for Nahrendorf's declaration that social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change.

Yet we would do well to remind ourselves that technology is a human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird locking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at   Chernobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use Our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination.

Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who declare that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not restricted to the few.

In somewhat similar fashion, computers promise to revolutionize the structure of American life, particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development to supplement and replace some aspects of the mind of human beings by electronic methods. It is the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society.

1. Why does the author give the examples of the Challenger and Chernobyl?
A.To show that technology could be used to destroy our world.
B.To stress the author's concern about the safety of complex technology.
C.To prove that technology usually goes wrong, if not controlled by man.
D.To demonstrate that being a human creation, technology is likely to make an error.
2. What does the phrase '"went haywire" in paragraph 2 most probably mean?
A.were out of rangeB.got out of control
C.fell out of useD.went out of date
3. According to the author, the introduction of the computer is a revolution mainly because________.
A.it has a great potential impact on society
B.it has helped to switch to an information technology
C.the computer has revolutionized the workings of the human mind
D.the computer can do the tasks that could only be done by people before
4. In the passage, the author clearly shows his____.
A.keen insight into the nature of technology
B.sharp criticism of the role of the Industrial Revolution
C.thorough analysis of the replacement of the human mind by computers
D.comprehensive description of the negative consequences of technology

8 . Zelda Fitzgerald, as is revealed by numerous personal books and letters, wore many labels in her life. She was “the original flapper girl” and “the spirit of the Jazz Age.” Married to the celebrated writer F. Scott Fitzgerald (author of The Gireat Giatsby), she was by turns his muse and the woman who ruined his life. In her later years she was “Crazy Zelda”.

Accurate as all these descriptions may be, they do not tell the whole story. Born in Montgomery, Alabama, she was noted for her beauty and high spirits in dancing. In July 1918, at a country club dance, Fitzgerald was hooked immediately by the beautiful and charming 18-year-old Zelda who out-shined(使逊色)other beauties with her distinguished ballet. A light affection evolved into a lengthy long-distance pursuit of weekly letters, with Fitzgerald aware of her uncommitted dating of other men. He courted her after his discharge from the Army in February 1919, but Zelda had doubts. Her fiance wasn't rich and there was no guarantee he’d ever be famous. His short stories didn’t sell. His apartment was a dump. Zelda gave back the ring. Hoping to fix the “no money” part of his problem. Fitzgerald quit the job and started to rewrite novels for success and money so that he could win back his girl. Finally, he made it! On March 20, 1920, his novel This Side of Paradise got published and Zelda agreed to marry him.

However, their marriage was troubled by wild drinking, fighting, infidelity(不忠实)and bitter recriminations. Emest Hemingway, whom Zelda disliked, blamed her for Scot’s declining literary output, though she has also been portrayed as the victim of an overbearing husbano Actually. Zelda was also creative, pursuing both dancing and writing. Some scholars have portrayed Zelda as a creative talent ignored by the patriarchal(男权的)society of the day. Her inspiration was even drawn by her husband in literary creation-Scott used their relationship as material in his novels, even borrowing episodes from Zelda’s diary and applying them into his fictional writings. She detested(讨厌)her husband’s practice: “Mr. Fitzgerald-I believe that is how he spells his name-seems to believe that plagiarism begins at home.” To seek an artistic identity of her own value, as she put it “I wish I could write a beautiful book to break those hearts that are soon to cease to exist.”

Nevertheless her unique personality was starting to seem more unbalanced than charming. The couple-like the rest of the nation-was living on borrowed time. In October 1929 the stock market crashed, triggering the Great Depression. Six months later, Zelda suffered her first nervous breakdown. After being diagnosed with schizophrenia(精神分裂), she was increasingly confined to specialist clinics, and since then has departed with her husband. Zelda died later in a fire at her hospital in Asheville, North Carolina, putting an end to her flamboyant(绚丽夺目的)life. A young woman, especially one in the 1920s, who was against traditional dress and behavior.

1. Where will you most probably find this article?
A.In a newspaper.B.In a literary magazine.
C.In a prepared speechD.In a research report.
2. Which phrase can best summarize the relationship between F. Scott Fitzgerald and Zelda?
A.Ideal partnershipB.Unbalanced love relationship.
C.Love-hate relationship.D.Mutually-jealous relationship
3. The underlined word “plagiarism” in paragraph three is closet in meaning to “________”.
A.copyingB.adaption
C.referenceD.imagination
4. Which of the following is true according to the article?
A.Fitzgerald successfully won Zelda’s heart by reading her his novels and writing her weekly letters.
B.Hemingway disliked Zelda because of her female identity and talent that outshined her husband.
C.Zelda was glad to be her husband’s muse and provided him with literary materials.
D.The “Crazy Zelda” died without Fitzgerald’s companion after severe schizophrenia.

9 . Aviculturists, people who raise birds for commercial sale, have not yet learned how to create similar conditions to the natural incubation (孵化) of parrot eggs in the wild. They continue to look for better ways to increase egg production and to improve chick survival rates.

When parrots incubate their eggs in the wild, the temperature and humidity (湿度) of the nest are controlled naturally. Heat is transferred from the bird’s skin to the top of the eggshell, leaving the sides and bottom of the egg at a cooler temperature. This temperature difference may be vital to successful hatching. Nest construction can contribute to this temperature difference. Nests of loosely arranged sticks, rocks, or dirt are cooler in temperature at the bottom where the egg contacts the nesting material. Such nests also act as humidity regulators by allowing rain to drain into the bottom sections of the nest so that the eggs are not in direct contact with the water. As the water that collects in the bottom of the nest changes into gas, the water vapor rises and is heated by the incubating bird, which adds significant humidity to the incubation environment.

In artificial incubation programs, aviculturists remove eggs from the nests of parrots and incubate them under laboratory conditions. Most commercial incubators heat the eggs fairly evenly from top to bottom, thus ignoring the bird’s method of natural incubation, and perhaps reducing the survivability of the hatching chicks.

When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors to use as nests in which to place eggs. In areas where weather can become cold after eggs are laid, it is very important to maintain a deep foundation of nesting material to protect eggs against the cold bottom of the box. If eggs rest against the wooden bottom in extremely cold weather conditions, they can become chilled to a point where the embryo (胚胎) can no longer survive Similarly, these boxes should be protected from direct sunlight to avoid high temperatures that are also fatal to the growing embryo.

Nesting material should be added in sufficient amounts to avoid both extreme temperature situations mentioned above and assure that the eggs have a soft, secure place to rest.

1. What is the main idea of the passage?
A.Nesting material varies according to the parrots’ environment.
B.Humidity is an important factor in incubating parrots’ eggs.
C.Aviculturists have constructed the ideal nest box for parrots.
D.Wild parrots’ nests provide information useful for artificial incubation.
2. According to paragraph 2, when the temperature of the sides and bottom of the egg are cooler than the top, then ________.
A.there may be a good chance for successful incubation
B.the incubating parent moves the egg to a new position
C.the embryo will not develop normally
D.the incubation process is slowed down
3. The construction of the nest allows water to ________.
A.provide a beneficial source of humidity in the nest
B.loosen the materials at the bottom of the nest
C.keep the nest in a clean condition
D.touch the bottom of the eggs
4. Which of the following is a problem with commercial incubators?
A.They are expensive to operate.
B.They are unable to heat the eggs evenly.
C.They lack the natural temperature changes.
D.They fail to transfer heat to eggs like parent birds do.

10 . Shining just 12 light-years from Earth, the star Tau Ceti so resembles the sun that it has appeared in numerous science- fiction stories and was the first star astronomers ever searched for signs of intelligent life, half a century ago. In 2012 Tau Ceti grew still more interesting when astronomers reported five possible planets somewhat larger than Earth circling closer to the star than Mars orbits (围绕……运动) the sun—one of which is in the star’s habitable zone. Newly released images taken by the Herschel Space Observatory provide even more insight about Tau Ceti’s solar system: greater detail about its dust belt.

Dust arises when asteroids and comets (小行星和彗星) crash into one another, so its location reveals where these dust- creating objects—which are too small to be seen directly—orbit a star. In Tau Ceti’s case, “it’s quite a wide dust belt,” says Samantha Lawler of the University of Victoria in British Columbia. As her team reported in November, the belt’s inner edge is roughly two to three astronomical units (AUs) from the star, which is the position of our own sun’s asteroid belt. (An AU is the distance from Earth to the sun.) Tau Ceti’s dust belt extends out to 55 AU, which would be just beyond our system’s main Edgeworth-Kuiper belt, the zone of small bodies whose largest member is probably Pluto. Presumably full of asteroids and comets, Tau Ceti’s dust belt most likely lacks a planet as large as Jupiter, Lawler says. The gravity of such a massive planet would have driven away most small space rocks.

Within a year a new series of radio telescopes in Chile called ALMA should provide a sharper view of the disk, especially of its inner edge. The ALMA images will help astronomers confirm whether the star’s five proposed planets are indeed real. If the disk overlaps the planets’ hypothesized (假设的) orbits, then they probably do not exist; they would have kept away most asteroids near the star, removing the source of dust.

If those planets do exist, however, Lawler’s team suggests that Tau Ceti’s planetary system may resemble what our solar system would have looked like had the four giant planets—Jupiter, Saturn, Uranus and Neptune- never formed: small planets orbiting close to the star, and nothing but asteroids, comets and dust beyond.

1. According to astronomers, the five possible planets of Tau Ceti________.
A.resembled Earth in size
B.functioned like a solar system
