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Which of the following is not a finding of the experiment?

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.
