[单项选择]Passage Four

Climate, more than any other single factor, determines the distribution of life on earth. Climatic boundaries establish the limits which organisms can survive. Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions are likely to occur. In the harsh conditions of the tundra, for example, low growing mosses, lichens, and a few flowering plants all hug the ground for shelter from icy winds. Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution. Others, such as bears are flexible enough to adapt to a broad range of climates. Oc A. to avoid being eaten by arctic animals B. because fertilizer is not readily available C. to minimize exposure to the cold D. because unfrozen water supplies are very scarce 查看答案 更多"Passage Four Climate, mor"的相关试题: [单项选择]Passage Four Climate, more than any other single factor, determines the distribution of life on earth.

More than 180,000 energy-guzzling refrigerators in public housing projects have been replaced with new ones that use a quarter of the power of the old ones. For years, New York has been the city that not only never sleeps, but the city that hardly ever remembers to turn the lights out. On the coldest days of winter, New Yorkers raise their windows to let out the heat. In the dog days of summer, a husky could freeze in the open doorway of a Fifth Avenue boutique. But now, measures like more efficient traffic lights and refrigerators are speeding up a long trend making New York one of the most energy-efficient cities in the nation--and officials in cities lik A. Environmentally conscious. B. Energy-efficient. C. Resource-wasting. D. Multicultural. 查看答案 [单项选择] Passage Four Severe climate change was the main driver behind the birth of civilisation, a scientist said yesterday. An increase in harsh, arid conditions across the globe around 5,000 years ago forced people to start living in stable communities around remaining water sources. "We can certainly say that the earliest civilisations arose on the backdrop of increasing dryness, which are driven by natural, global-scale changes in climate," said Nick Brooks of the University of East Anglia. "The cultural transitions track changes in environmental conditions quite closely." Dr. Brooks said his research turned traditional ideas of how the world’s first civilisations started--such as those in Egypt, China, the Indus Valley region and South America---on their head. Many anthropologists think that civilisation was spread gradually among populations after it began in some part of the world. ’A current popular th A. differences in civilizations are the result of differences in climate conditions B. the emergence of civilizations is closely related to climate change C. the development of civilizations has caused the world climate change D. similar civilizations have appeared despite various climate conditions 查看答案 [简答题]Some people have a better sense of humor than others just as some people have more musical talent, mathematical talent etc. than others. 查看答案 [单项选择] More than any other country, America defines itself by a collective dream: the dream of economic opportunity and upward mobility. Its proudest boast is that it offers a chance of the good life to everybody who is willing to work hard and play by the rules. This ideal has made the United States the world’s strongest magnet for immigrants; it has also reconciled ordinary Americans to the rough side of a dynamic economy, with all its inequalities and insecurities. Who cares if the boss earns 300 times more than the average working staff, if the staff knows be can become the boss Look around the world and the supremacy of "the American model" might seem assured. No other rich country has so successfully harnessed the modern juggernauts of technology and globalization The hallmarks of American capitalism—a willingness to take risks, a light regulatory touch and sharp competition—have spawned enormous wealth.
