单选题Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers break up everything that can be broken. Finally the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage. The first full scale giant recycling plants are, perhaps, fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will-be forced to build their own recycling plants before long.

单选题The Mona Lisa painting now hangs in the Musee du Louvre in Paris. The painting"s increasing fame was further emphasized when it was stolen on 21 August 1911. The next day, Louis Beroud, a painter, walked into the Louvre and went to the Salon Carre where the Mona Lisa had been on display for five years. However, where the Mona Lisa should have stood, he found four iron pegs. Beroud contacted the section head of the guards, who thought the painting was being photographed for marketing purposes. A few hours later, Beroud checked back with the section head of the museum, and it was confirmed that the Mona Lisa was not with the photographers. The Louvre was closed for an entire week to aid in investigation of the theft. French poet Guillaume Apollinaire, who had once called for the Louvre to be "burnt down," came under suspicion; he was arrested and put in jail. Apollinaire tried to implicate his friend Pablo Picasso, who was also brought in for questioning, but both were later exonerated. At the time, the painting was believed to be lost forever, and it was two years before the real thief was discovered. Louvre employee Vincenzo Peruggia had stolen it by entering the building during regular hours, hiding in a broom closet and walking out with it hidden under his coat after the museum had closed. Peruggia was an Italian patriot who believed Leonardo"s painting should be returned to Italy for display in an Italian museum. Peruggia may have also been motivated by a friend who sold copies of the painting, which would skyrocket in value after the theft of the original. After having kept the painting in his apartment for two years, Peruggia grew impatient and was finally caught when he attempted to sell it to the directors of the Uffizi Gallery in Florence; it was exhibited all over Italy and returned to the Louvre in 1913. Peruggia was hailed for his patriotism in Italy and only served six months in jail for the crime. During World War II , the painting was again removed from the Louvre and taken safely, first to Chateau d"Amboise, then to the Loc Dieu Abbey and Chateau de Chambo-rd, then finally to the Ingres Museum in Montauban. In 1956, the lower part of the painting was severely damaged when a vandal doused the painting with acid. On 30 December of that same year, a young Bolivian named Ugo Ungaza Villegas damaged the painting by throwing a rock at it. This resulted in the loss of a speck of pigment near the left elbow, which was later painted over. The use of bulletproof glass has shielded the Mona Lisa from more recent attacks. In April 1974, a handicapped woman, upset by the museum"s policy for the disabled, sprayed red paint at the painting while it was on display at the Tokyo National Museum. On 2 August 2009, a Russian woman, distraught over being denied French citizenship, threw a terra cotta mug or teacup, purchased at the museum, at the painting in the Louvre; the vessel shattered against the glass enclosure. In both cases, the painting was undamaged.

单选题No woman can be too rich or too thin. This saying often attributed to the late Duchess (公爵夫人) of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better—or worse—part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown relative dies suddenly in some distant land, leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent? All religions have certain days when people refrain from eating, and excessive eating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat—or even only somewhat overweight—is bad because it implies a lack of moral strength. Our obsession (迷恋) with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem—too much fat and a lack of fiber—than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vainglory (虚荣).

单选题Passage 5 What our society suffers from most today is the absence of consensus about what it and life in it ought to be, such consensus cannot be gained from society's present stage, or from fantasies about what it ought to be. For that the present is too close and too diversified, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared understanding of the past, as Homer's epics informed those who lived centuries later what it meant to be Greek, and by what images and ideals they were to live their lives and organize their societies. Most societies derive consensus from a long history, a language all their own, a common religion, common ancestry. The myths by which they live are based on all of these. But the United States is a country of immigrants, coming from a great variety of nations. Lately, it has been emphasized that an asocial, narcissistic personality has become characteristic of Americans, and that it is this type of personality that makes for the lack of well-being, because it prevents us from achieving consensus that would counteract a tendency to withdraw into private worlds. In this study of narcissism, Christopher Lash says that modern man, "tortured by self-consciousness, turns to new therapies not to free himself of his personal worries but to find meaning and purpose in life, to find something to live for". There is widespread distress because national morale has declined, and we have lost an earlier sense of national vision and purpose. Contrary to rigid religions or political beliefs, as are found in totalitarian societies, our culture is one of the great individual differences, at least in principle and in theory; but this leads to disunity, even chaos. Americans believe in the value of diversity, but just because our is a society based on individual diversity, it needs consensus about some dominating ideas more than societies based on uniform origin of their citizens. Hence, if we are to have consensus, it must be based on a myth--a vision about a common experience, a conquest that made us Americans, as the myth about the conquest of Troy formed the Greeks. Only a common myth can offer relief from the fear that life is without meaning or purpose. Myths permit us to examine our place in the world by comparing it to a shared idea. Myths are shared fantasies that form the tie that binds the individual to other members of his group. Such myths help to ward off feelings of isolations, guilt, anxiety, and purposelessness--in short, they combat isolation and the breakdown of social standards and values.

单选题NASA is releasing several images taken by the Hubble Space Telescope, which is the closest yet look at the red planet. Altogether there are four images, which show the entire planet. Each view shows the planet as it completes one quarter of its daily rotation. In these views the north polar cap is turned toward the Earth and is clearly visible at the top of each picture. The images were taken in the middle of the Martian northern summer, when the polar cap was at its smallest size. During this season the sun shines continuously on the polar cap. Previous spacecraft observations have shown that this summertime polar cap is composed of water ice, just like Earth's polar caps. The Hubble Telescope pictures reveal that great changes have occurred on the surface of Mars in the past 20 years. The Martian surface is ever changing. Some regions that were dark 20 years ago are now bright red; some areas that were bright red are now dark. Winds move sand and dust from region to region, often in huge dust storms. Over long timescales many of the larger bright and dark markings remain stable, but smaller details come and go as they are covered and then uncovered by sand and dust.
