单选题Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight, one of the scientists wrote in his book. "Look here for probable metal. " Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, "Gold possible. " Walking across hilly ground. four scientists reported, "This ground should be searched for metal. " From an airplane over a hilly wasteland a scientist sent back by radio one word: "Uranium. " None of the scientists had X-ray eyes: they had no magic power of looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground... trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow in the surface. At Watson Bar Greek, a brook (小溪) six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory, the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches.

单选题{{B}}Text 1{{/B}} {{B}} An embarrassing experience{{/B}} It was the small hours of the morning when we reached London Airport. I had cabled London from Amsterdam, and there was a hired car to meet, but there was one more unfortunate happening before I reached my flat. In all my travels I have never, but for that once, been required by the British customs to open a single bag or to do more than state that I carried no goods liable to duty. It was, of course, my fault; the extreme tiredness and nervous tension of the journey had destroyed my diplomacy. I was, for whichever reason, so tired that I could hardly stand, and to the question, "have you read this?" I replied with extreme foolishness," Yes, hundreds of times. " "And you have nothing to declare?" "Nothing." "How long have you been out of this country?" "About three months." "And during that time you have acquired nothing?" "Nothing but what is on the list I have given you. He seemed momentarily at a loss, but then he attacked. The attack, when it came, was utterly unexpected. "Where did you get that watch?" I could have kicked myself. Two days ago, when playing water games with a friend in the bath, I had forgotten to take off my ROLEX OYSTER, and it had, not unnaturally, stopped. I had gone into the market and bought, for twelve shillings and six pence, an ugly time piece that made a strange noise. It had stopped twice, without any reason, during the journey. I explained, but I had already lost face. I produced my own watch from a pocket, and added that I should be grateful if he would confiscate the replacement. "It is not a question of confiscation," he said, "there is a fine for failing to declare dutiable goods. And now may I please examine that Rolex?" It took another quarter of an hour to persuade him that the Rolex was not contraband; then he began to search my luggage.

单选题Some animals apparently can resist cancer by strengthening their immune system in preparation for winter, Johns Hopkins researchers said on Wednesday. The scientists said their study is the first to show that the central nervous system, reacting to environmental changes, may spark changes in the body's immune system that control the growth of tumors. They said if that is the ease, a better understanding of how the process works eventually could lead to new cancer treatments. Dr. Randy Nelson, an associate professor of psychology at Hopkins, stressed at a meeting of the Society of Neuroscience that further study would be needed to confirm a connection between the length of the day, the animals' immune system and cancer. More work also would be needed to show that the findings could be applied to human cancer. Dr. Faye Austin, an immunologist with the National Cancer Institute in Bethesda, said: "It's a very intriguing observation that the length of exposure to light can affect the growth of a tumour. But I think that the draws really need further work to clarify the mechanics." But Austin said the findings were surprising and important, only because they open up a new approach for research. Studies showed that stress weakened the immune system in animals. They figured that because winter is stressful, the season probably causes exertion (影响) on the immune system. The researchers reasoned that animals that compensated by boosting (促进) their immune systems as winter approached would have a better chance of surviving and producing offspring. "In the same way that animals have evolved to select the best time to breed, it struck me that animals ought to be able to predict when conditions would be challenging immunologically." Nelson said.

单选题Once upon a time there was a man who had fifty red nightcaps to sell at a fair. His wife put them into a great bag for him which he carried over his shoulder. It was a very hot day. Now the man's way lay through a wood. When he came to the shade, he put down his bag and sat down to rest. Soon he took one of the red nightcaps out of his bag, put it on, lay down and went to sleep. Now there were monkeys in that wood, and by and by a big old ape came stealing down out of the trees and took one of the red nightcaps out of the bag, put it on his head, and ran up into a tree and sat there grinning and chattering. By and by another ape came stealing down and he too took a red nightcap, put it on and ran up into a tree and he too sat in the tree grinning and chattering. Then another ape took another cap, and then another, until at last there were forty nine monkeys in forty nine red nightcaps, sitting in the trees chattering and calling out.

单选题{{B}}Text 1{{/B}} A former town hall worker made legal history last week when she was awarded 67,000 pounds for stress brought on by her work. The ruling made Beverley Lancaster the first person to get their employer to accept legal responsibility for stress-related personal injury in a British court. It is likely to start a flood of other worker’s claims; Mrs. Lancaster’s union already has 7,000 stress-related cases on its books. The 44-year-old mother of two started a legal case against Birmingham City Council after falling ill while working as a troubleshooter in a neighborhood housing office. Dealing with rude and abusive members of the public pushed her into periods of gloom and she suffered anxiety, Birmingham county court heard. Mrs. Lancaster joined the council at 16, working her way up from junior clerk to senior draughtswoman. Her problems began when she was promoted to housing officer in Sutton Oldfield. "With no continuity, a constant high workload and little clerical support, I found it difficult to switch from one problem or situation to another," she said. "My concentration swung and I suffered sleepless nights. It made me feel like I was in a hole with no key to open the door. I would break down in tears. I was being in paperwork and at times my mind would just go blank." In awarding compensation of 67,491 pounds, assistant recorder Frances Kirkham said she understood the position of troubleshooter was very different from Mrs. Lancaster’s precious job. She rejected claims from the council that Mrs. Lancaster would be able to go back to her former profession, saying she accepted that the possibility of future work would be less capacity. After the hearing Mrs. Lancaster said she was relieved and pleased. She added, "I hope this will act as a warning to employers. Everything I did was right. The council made promises to me and they failed me. I felt isolated, let down, that I was not good enough, not wanted." The payout, the first of its kind to be decided in a county court, covers loss of wages and future loss of earnings. A spokesman for Birmingham City Council said action had been taken by the authority to review its staff and management procedures.

单选题

单选题Are you happy? Do you remember a time when you were happy? Are you seeking happiness today? Many have sought a variety of sources for their feeling of happiness. Some have put their heart and efforts into their work. Too many turned to drugs and alcohol. Meanwhile, untold numbers have looked for it in the possession of expensive cars, exotic vacation homes and other popular "toys". Most of their efforts have a root in one common fact: people are looking for a lasting source of happiness. Unfortunately, I believe that happiness escapes from many people because they misunderstand the journey of finding it. I have heard many people say that, "I'll be happy when I get my new promotion," or "I'11 be happy when I get that extra 20 pounds." It is dangerous because it accepts that happiness is a "response" to having, being or doing something. In life, we all experience stimulus and response. Today, some people think that an expensive car is stimulus. Happiness is a response. A great paying job is stimulus. Happiness is a response. This belief leaves us thinking and feeling: "I'll be happy when ..." It has been my finding that actually the opposite is true. I believe that happiness is a stimulus and response is what life brings to those who are truly happy. When we are happy, we tend to have more success in our work. When we are happy, we more naturally take better care of our bodies and enjoy good health. Happiness is not a response but a stimulus. Happiness is a conscious choice we make in daily life. For unknown reasons to me, many choose to be upset and angry most of the time. Happiness is not something that happens to us after we get something we want—we usually get things we want after we choose to be happy.
