  2.概括大意与完成句子:(www.xuehuiba.com)版权所有www.xuehuiba.com

  The molecules of carbon dioxide in the Earth's atmosphere affect the heat balance of the Earth by acting as a one-way screen. Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength infrared emissions radiated from the Earth's surface, radiation that would otherwise be transmitted back into space. For the Earth's surface, radiation that would otherwise be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must balance incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would escape from the Earth much more easily. The surface temperature would be so much lower that the oceans might be a solid mass of ice.

  Today, however, the potential problem is too much carbon dioxide. The burning of fossil fuels and the clearing of the forests have increased atmospheric carbon dioxide by about 15 percent in the 1st hundred years, and we continue to add carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature and could such a rise have serious consequences for human society? Mathematical models that allow us to calculate the rise in temperature as a function of the increase indicate that the answer is probably yes.

  Under present conditions a temperature can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature increases by about per kilometer approaching the Earth's surface, where the average temperature is bout. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. As the capacity of the atmosphere to absorb infrared radiation increase, the radiating level and the temperature of the surface must rise.

  One mathematical model predicts that doubling the atmospheric carbon dioxide would raise the global mean surface temperature. This model assumes that the atmosphere's relative humidity remains constant and the temperature decreases with altitude at a rate of per kilometer.

  The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelengths. Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises. Therefore, more infrared radiation would be adsorbed and reradiated back to the Earth's surface. The resultant warming at the surface could be expected to melt snow and ice, reducing the Earth's reflectivity. More solar radiation would then be absorbed, leading to a further increase in temperature.

  23. Paragraph 1 ______

  24. Paragraph 3 ______

  25. Paragraph 4 ______

  26. Paragraph 5 ______

  A. The prediction of the model

  B. The influence on temperature

  C. The effect of carbon dioxide

  D. The potential problem

  E. The import of the assumption

  F. The serious consequences

  27. Nowadays, too much carbon dioxide ______.

  28. The radiating level and the temperature of the surface must rise because of _____.
