单选题Mark went to the neighborhood meeting after work. The area's city councilwoman (女议员) was leading a discussion about how the quality of life was decreasing. The neighborhood faced many problems. People were supposed to suggest solutions to the councilwoman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here. " On his way back, Mark saw a woman carrying a grocery bag and baby. She was trying to unlock her car, but she didn't have a free hand. As Mark got closer, her other child, a little boy, suddenly darted into the street. The woman tried to reach for him, but as she moved, her bag shifted and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You've got great timing (适时)!" "Just being neighborly (友好的)," Mark said. As he rode home, he glanced at the walls of the bus passed by. On one of them was "Small acts of kindness add up. " Mark smiled and thought, "Maybe that's a good place to start. /

单选题 The idea of a fish being able to generate electricity strong enough to light lamp bulbs—or even to run a small electric motor—is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families. Perhaps the best known are the electric rays, or torpedoes (电鱼), of which several kinds live in warm seas. They posses on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of fiat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a special part of the brain. Current passes from the upper, positive side of the organ downwards to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock. The strength of this shock depends on the size of the fish, but newly born ones only about 5 centimeters across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for several minutes. Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally (纵 向) and are supplied with nerves from the spinal (脊骨) cord. Consequently, the current passes along the fish from head to tail. The electric or gans of these fish are really altered muscles and like all muscles are apt (likely)to tire, so they are not able to produce electricity for very long. The power of producing electricity may serve these fish both for defence and attack.

单选题{{B}}Passage Two{{/B}} Despite not being terribly smart as individuals, wasp (黄蜂) colonies build and maintain a complex nest that lasts many generations. Just how these social wasps coordinate this task has always been a mystery. But now a mathematical model suggests that one key factor drives their behavior: the amount of water in the nest. Social wasps cannot learn from one another—unlike bees, which use a complex dance to tell nest mates where sources of nectar (花蜜) are. Nor do they use pheromones (信息素) the way ants do to lead other ants to food. Robert Jeanne of the University of Wisconsin-Madison proposed that wasps set up a demand-driven chain of information. At the end of the chain, builder wasps monitor the nest and when necessary, request pulp from pulp forager wasps. They in turn demand water from water foragers in order to make the pulp. But biologist Istvan Karsai of East Tennessee State University in Johnson City, Tennessee, and his team found that social wasps in Panama don't actually work that way. They removed either builders or pulp foragers from a colony of a species called Metapolybia aztecoides. Although that should break up the so-called information chain, it did not significantly alter the amount of water being brought into the nest. They also found that the wasps could change roles, something that Jeanne didn't expert. For instance, when the researchers sprayed a surplus of water onto the nest, water foragers quickly became builders, and nest building increased. Based on their observations, Karsai's team developed a mathematical model that shows that wasps achieve their complex behaviour simply by monitoring the level of water in the nest—what he calls the"common stomach" of the colony. He believes wasps infer what the level is when they exchange fluids on meeting each other, a behaviour called trophallaxis that is common in many social insects. To test the model, Karsai simulated changes in the model colony, for example by removing pulp foragers or builders. "What's interesting is that in every case the model responds like the actual colony in Panama, "says Karsai.

单选题This story began about 10 years age. I was coming out of a very bad marriage. For seven long years my husband spent his every waking moment telling me just what was wrong with me. When I finally asked for a divorce, he answered by telling me that I would never find anyone to love me because I was just so unattractive. This went on for about two years. One night one of my friends convinced me to go out with her. We went to a nightclub and that's when I met him. Clint was playing a game with a girl. I sat in the corner watching him. I didn't feel that I had whatever it took to get up and mix with others because of my self-esteem problem. Finally I got up the courage to order a drink for him. When he got it, he gave me the most dazzling smile. We spent the rest of the evening talking until I realized that it was almost morning. I figured that he was simply being nice to me because I had bought him a drink, but the very next day he called and told me that he could not stop thinking about me and that he wanted to meet my kids too. (81) About 3 months later, my divorce was final and Clint sat my boys down and asked them if it was all right with them if he asked me to marry him because he could not imagine life without the three of us anymore. I was so touched that he went to my boys and asked for their approval because they were the "men of the house" at the ripe old ages of 2 and 4. They said yes and we have all been together ever since. Clint gave me and my boys a second chance at a wonderful life. (82) Not a day goes by that he doesn't tell we are the best thing that ever has happened to him and that he loves us.

单选题The economic recession of the 1980s and its impact on the quality of life in Third World countries highlighted how important health is for development and how essential it is for concern about public health to feature at the very heart of development policies. The fact is that it is no longer possible to meet the soaring costs of health and the emergence of new risks — such as AIDS — unless health is built in among the priority economic objectives. Health and development are indissolubly linked, and the era when health tended to rate very low in the list of economic targets is past and gone. But a lot remains to be done: the health care services can no longer be left on their own to face up to those new situations, which must be taken into consideration whenever each country constantly reviews its economic objectives. It was long thought that technical progress would provide the solution to all health problems. That this is not the case is proved by the impact that environmental degradation has had on human health, by the pandemic of AIDS, by the way the much greater mobility of people has encouraged the rapid transmission of diseases, and by the health consequences of modern life-styles. Today we have to find radically new approaches if we are to avoid the present world situation turning into an uncontrollable health. It is essential for national policy-makers in the field of social welfare to give every citizen much greater decision-making power, especially by ensuring that vulnerable communities have direct access to decisions which concern them. Individuals and communities must be given the opportunity to assume far greater responsibility for their own health and quality of life, by creating a climate that is favourable to well-being and by offering the necessary incentives and support. Independent bodies such as nongovernmental organizations also have an important role to play in making widely available the information and awareness that people must have if they are to make the right choices and take the right social decisions. This is one of the greatest challenges as we approach the end of the twentieth century. If we show ourselves ready to meet that challenge, the citizens of the third millennium will have the knowledge and the means empowering them to build a society where health — a human right for every man and woman — will be within the reach of all.

单选题I was a freshman in college when I met the Whites. They were completely different from my own family, yet I felt at home with them immediately. Jane White and I became friends at school, and her family welcomed me like a long-lost cousin. In my family, it was always important to place blame when anything bad happened. "Who did this?" my mother would scream about a dirty kitchen. "This is all your fault, Katharine," my father would insist when the cat got out or the dishwasher broke. From the time we were little, my sister, brothers and I told on each other. We set a place for blame at the dinner table. But the Whites didn't worry about who had done what. They picked up the pieces and moved on with their lives. The beauty of this was driven home to me the summer Jane died. In July, the White sisters and I decided to take a car trip from their home in Florida to New York. The two older sisters, Sarah and Jane, were college students, and the youngest, Amy, had recently turned sixteen. Proud of having a new driver's license(驾照), Amy was excited about practicing her driving on the trip. She showed off her license to everyone she met. The big sisters shared the driving of Sarah's new car during the first part of the trip, but when they reached less crowded areas, they let Amy take over. Somewhere in South Carolina, we pulled off the highway to eat. After lunch, Amy got behind the wheel. She came to a crossroads with a stop sign. Whether she was nervous or just didn't see the sign no one would ever know, but Amy continued into the crossroads without stopping. The driver of a large truck, unable to stop in time, ran into our car. Jane was killed immediately. I was slightly injured. The most difficult thing that I've ever done was to call the Whites to tell them about the accident and that Jane had died. Painful as it was for me to lose a good friend, I knew that it was far worse for them to lose a child. When Mr. and Mrs. White arrived at the hospital, they found their two daughters sharing a room. Sarah had a few cuts on the head; Amy's leg was broken. They hugged(拥抱)us all and cried tears of sadness and of joy at seeing their daughters. They wiped away the girls' tears and made a few jokes at Amy as she learned to use her crutches(拐杖). To both of their daughters, and especially to Amy, over and over they simply said, "We're so glad that you're alive." I was astonished. No blame. No accusations. Later, I asked the Whites why they never talked about the fact that Amy was driving and had run a stop sign. Mrs. White said, "Jane's gone, and we miss her terribly. Nothing we say or do will ever bring her back. But Amy has her whole life ahead of her. How can she lead a full and happy life if she feels we blame her for her sister's death?" They were right. Amy graduated from the University of California and got married several years ago. She works as a teacher of learning-disabled students. She's also a mother of two little girls of her own, the older named Jane.
