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 3{{/B}} When some nineteenth-century New Yorkers said "Harlem", they meant almost all of Manhattan above Eighty-sixth Street. Toward the end of the century, however, a group of citizens in upper Manhattan—wanting, perhaps, to shape a closer and more precise sense of community— designated a section that they wished to be known as Harlem. The chosen area was the Harlem to which Blacks were moving in the first decades of the new century as they left their old settlements on the middle and lower blocks of the West Side. As the community became predominantly Black, the very word "Harlem" seemed to lose its old meaning. At times, it was easy to forget that "Harlem" was originally the Dutch name "Harrlem", that the community it described had been founded by people from Holland; and that for most cites three centuries—it was first settled in the sixteen hundred it had been occupied by White New Yorkers. "Harlem" became synonymous with Black life and Black style in Manhattan. Blacks living there used the word as though they had coined it themselves—not only to designate their area of residence but to express their sense of the various of its life and atmosphere. As the years passed, "Harlem" assumed an even larger meaning. In the words of Adam Clayton Powell, the pastor of the Abyssinian Baptist Church, Harlem "became the symbol of liberty and the promised land to the Negroes. Everywhere". By 1919, Harlem's population had grown by several thousand. It had received its share of wartime migration from the South, the Caribbean, and parts of colonial Africa. Some of the new arrivals merely lived in Harlem. It was New York they had come to, looking for jobs and for all the other legendary opportunities of life in the city. To others who migrated to Harlem, New York was merely the city in which they found themselves; Harlem was exactly where they wished to be.
