单选题{{B}}Questions 16-20 are based on the following passage:{{/B}} 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.

单选题Sea horses have unusual parents. The female sea horses lay the eggs, but unlike other creatures. It's the males that give birth to the young. Male sea horses have a fold of skin on their bellies that forms a pocket, called a brood pouch. During the breeding season, the sea horse's pouch swells to receive eggs. A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return every day to check on her mate and the eggs, but she doesn't stay long,nor does she take part in the birth. It takes from five to six weeks for the eggs in the male's pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult from him to swim, so the male often uses his tall to grasp a piece of sea grass. Firmly, gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change Iris color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs. The eggs hatch inside the male's pouch. When the babies begin moving around, the mate sea horse knows it's time for them to be born. He grabs a sea grass stem with his tail and begins rocking, bending his body back and forth, this causes the opening to enlarge until wide enough for the first baby sea horse to shoot out. the father sea horse continues rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out. Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tiered when it's over. Soon after giving birth to one brood, the male will approach his mat and show her his empty pouch. This tells her he is ready to receive eggs again.

单选题{{B}}Passage Two{{/B}} The component of the healthy personality that is the first to develop is the sense of the trust. The crucial time for its emergence is the first year of life. As with other personality components, the sense of trust is not something that develops independent of other manifestations of growth. It is not that infants learn how to use their bodies for purposeful movement, learn to recognize people and objects around them, and also develop a sense of trust. Rather, the concept "sense of trust" is a shortcut expression intended to convey the characteristic flavor of all the child's satisfying experiences at this early age. Or, to say it another way, this psychological formulation serves to condense, summarize, and synthesize the most important underlying changes, which give meaning to the infant's concrete and diversified experience. Trust can exist only in relation to something. Consequently, a sense of trust cannot develop until infants are old enough to be aware of objects and persons and to have some feeling that they are separate individuals. At about 3 months of age, babies are likely to smile, if somebody comes close and talks to them. This shows that they are aware of the approach of the other person, that pleasurable sensations are aroused. If, however, the person moves too quickly or speaks too sharply, these babies may look and cry. They will not "trust" the unusual situation but will have a feeling of uneasiness, of mistrust, instead. Experience connected with feeding are a prime source for the development of trust. At around 4 months of age, a hungry baby will grow quiet and show signs of pleasure at the sound of an approaching footstep, anticipating (trusting) that he or she will be held and fed. This repeated experience of being hungry, seeing food, receiving food, and feeling relieved and comforted assures the baby that the world is a dependable place. Later experiences, starting at around 5 months of age, add another dimension to the sense of trust. Though endless repetitions of attempts to grasp for and hold objects, most babies are finally successful in controlling and adapting their movements in such a way as to reach their goal. Through these and other feats of muscular coordination, babies are gradually able to trust their own bodies to do their bidding. Studies of mentally-ill individuals and observations of infants who have been grossly deprived of affection suggest that trust is an early-formed and important element in the healthy personality. Psychiatrists find again and again that the most serious illnesses occur in patients who have been sorely neglected or abused or otherwise deprived of love in infancy. Similarly, it is a common finding of psychological and social investigators that individuals diagnosed as "psychopathic personalities" were so unloved in infancy that they have no reason to trust the human race and therefore, no feeling of responsibility toward their fellow human beings.

单选题{{B}}Questions 21-25based on the following passage:{{/B}} As people continue to grow and age, our body systems continue to change. At a certain point in your life your body systems will begin to weaken. Your joints may become stiff. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this process that leads us toward the end of our lives. Many factors contribute to your health. A well-balanced diet plays an important role. The amount and type of exercise you get is another factor. Your living environment and the amount of stress you are under is yet another. But scientists studying senescence (衰老) want to know: Why do people grow old? They hope that by examining the aging process on a cellular level medical science may be able to extend the length of life.

单选题{{B}}26-30{{/B}} A few common misconceptions. Beauty is only skin-deep. One's physical assets and liabilities don't count all that much in a managerial career. A woman should always try to look her best. Over the last 30 years, social scientists have conducted more than 1,000 studies of how we react to beautiful and not-so-beautiful people. The virtually unanimous conclusion: Looks do matter, more than most of us realize. The data suggest, for example, that physically attractive individuals are more likely to be treated well by their parents, sought out as friends, and pursued romantically. With the possible exception of women seeking managerial jobs, they are also more likely to be hired, paid well, and promoted. Un-American, you say, unfair and extremely unbelievable? Once again, the scientists have caught us mouthing pieties (虔诚) while acting just the contrary. Their typical experiment works something like this. They give each member of a group-college students, perhaps, or teachers or corporate personnel managers a piece of paper relating an individual's accomplishments. Attached to the paper is a photograph. While the papers all say exactly the same thing the pictures are different. Some show a strikingly attractive person, some an average-looking character, and some an unusually unattractive human being. Group members are asked to rate the individual on certain attributes, anything from personal warmth to the likelihood that he or she will be promoted. Almost invariably, the better looking the person in the picture, the higher the person is rated. In the phrase, borrowed from Sappho, that the social scientists use to sum up the common perception, what is beautiful is good. In business, however, good looks cut both ways for women, and deeper than for men. A Utah State University professor, who is an authority on the subject, explains: In terms of their careers, the impact of physical attractiveness on males is only modest. But its potential impact on females can be tremendous, making its easier, for example, for the more attractive to get jobs where they are in the public eye. On another note, though, there is enough literature now for us to conclude that attractive women who aspire to managerial positions do not get on as well as women who may be less attractive.

单选题Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world" population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn"t have to be the outcome. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past, just as we began to appreciate petroleum more after the 1970s oil Crisis. Today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.
