[单项选择]Passage Two

Children live in a world in which science has tremendous importance. During their lifetimes it will affect them more and more. In time, many of them will work at jobs that depend heavily on science--for example, concerning energy sources, pollution control, highway safety, wilderness conservation, and population growth. As taxpayers they will pay for scientific research and exploration. And, as consumers, they will be bombarded (受到轰击) by advertising, much of which is said to be based on science. Therefore, it is important that children, the citizens of the future, become functionally acquainted with science--with the process and spirit of science, as well as with its facts and principles. Fortunately, science has a natural appeal for youngsters. They can relate it to so many things that they encounter--flashlights, tools, echoes A. work in scientific research institutions B. work at jobs closely related to science C. make the final decision in matters concerning science D. be fund-raisers for scientific research and exploration 查看答案 更多"Passage Two Children live"的相关试题: [单项选择]Passage Two Children live in a world in which science has tremendous importance.

The crusher claw is short and stout; the cutter claw is long and slender. Such bilateral asymmetry, in which the right side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are right-handed, in lobsters the crusher claw appears with equal probability on either the right side or left side of the body. Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutterlike. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws further diverge toward well-defined cutter and crusher claws during succeeding stages. An intriguing aspect A. drawing an analogy between asymmetry in lobsters and handed in humans. B. developing a method for predicating whether crusher claws in lobster will appear on the left or right side C. explaining differences between lobsters’ crusher claws and cutter claws D. discussing a possible explanation for the way bilateral asymmetry is determined in lobsters 查看答案 [单项选择]Passage Two If two scientists at Los Alamos National Laboratory are correct, People will still be driving gasoline-powered cars 50 years from now, giving out heat-trapping carbon dioxide into the atmosphere--and yet that carbon dioxide will not contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have patriotically named Green Freedom for removing carbon dioxide from the air and turning it back into gasoline. The idea is simple. Air would be blown over a liquid solution which would absorb the carbon dioxide. The carbon dioxide would then be extracted and subjected to chemical reactions that would turn it into fuel. Although they have not yet built a fuel factory, or even a small prototype, the scientists say it is all based on existing technology. "Everything in the co A. It is given a patriotic name. B. No law of physics is violated. C. It is based on existing technology. D. Carbon dioxide can be converted into fuel. 查看答案 [填空题]Passage Two At two minutes to noon in September 1 of 1923, the great clock in Tokyo stopped.
