To many web-building spiders, most of 【C1】______ are nearly blind, the web is their essential window 【C2】______ the world: their means of communicating, 【C3】______ prey, meeting mates and protecting themselves. A web-building spider 【C4】______ its web is like a man marooned on an island of solid rock, totally out of touch and destined to starve to death. So 【C5】______ is the web to an orb-web spider's survival that the animal will continue to construct new webs daily 【C6】______ it is being starved. For 16 days the 【C7】______ spider builds completely normal webs. Then, as the animal gets scrawnier, it constructs a wider-meshed web using 【C8】______ strands. Such webs would only trap larger prey, which is more 【C9】______ from the perspective of a starving spider. The spider 【C10】______ energy by recycling web protein. It simply eats its own web each evening and reuses it to manufacture 【C11】______ silk. In studies with radioactively labeled materials, it 【C12】______ that 95 percent of web protein reappeared in 【C13】______ web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are 【C14】______ by the adaptability of the spider's highly preprogrammed brain, which is larger 【C15】______ its size than the brain of any other invertebrate. If web-building is interrupted, or if some of the 【C16】______ strands are destroyed, the spider 【C17】______ retraces its steps to see where the web is 【C18】______ and then finishes building a 【C19】______ web. One spider will even finish building the incomplete web of 【C20】______ . 【C1】 A．them B．whom C．that D．which

"Surveillance is very clearly our first line of defense, but it only works if there is transparency, if there is timely sharing of information, and if there is a spirit of cooperation," he said. Mr. Leavitt made the remarks on Monday in Jakarta, having previously visited Thailand, Cambodia, Laos, and Vietnam, along with Indonesia the' countries most seriously affected by bird flu. While most of the people who have contracted the disease have caught it from close contact with infected poultry, scientists are concerned the disease may change to one easily passed between people, causing a pandemic that could kill millions. Mr. Leavitt says the H5N1 virus has the potential to affect the world economically, socially, and politically. "The world is a biologically dangerous place right now. Avian influenza is spreading to other nations and to other continents, An outbreak anywhere means that there is risk everywhere," added Mr. Leavitt. "No nation can afford to ignore this. The effects of a pandemic go well beyond personal health. They affect economics, they affect politics, they affect social issues, and social concerns." Secretary Leavitt stressed_______ in the process of fighting H5N1 bird flu virus. A．research and development of new medicine B．new devices of prevention C．separation of infectors D．surveillance and information exchange

Dr. Jorge Yunis of the University of Minnesota Medical School in Minneapolis has found that 70 percent of oncogenes, or cancer-causing genes, are located near inherited weak points on chromosomes(染色体). Varying from individual to individual, vulnerable to chemical carcinogens(致癌剂), X rays and other cancer-inducing agents. "If a chromosome snaps apart in the immediate vicinity of an oncogene," says Yunis, "normal genetic control mechanisms could break down and the stage would be set for the formation of cancer." Younis has shown that such a sequence occurs at the beginning of numerous leukemias (白血病), lymphomas(淋巴瘤) and some tumors of the lung, colon(结肠) and breast. Yunis and other investigators have found that petroleum-based products--notably pesticides and insecticides-damage specific sites on at least two of the 23 pairs of human chromosomes that carry genetic information. Similarly, tobacco smoke tends to attack a part of another chromosome. From paragraph 1, we know that some 40 genes involving in cancer are ______. () A．harmful to the human body B．necessary to the human body C．the elements that form. cancer D．useless to the human body
