　　The molecules of carbon dioxide in the Earths

　　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

　　5 the energy of sunlight is concentrated, to pass

　　through, they absorb some of the longer-wavelength,

　　infrared emissions radiated from the Earths surface,

　　radiation that would otherwise be transmitted back

　　into space. For the Earth to maintain a constant aver age

　　10 temperature, such emissions from the planet must

　　balance incoming solar radiation. If there were no

　　car-bon 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

　　3. According to the passage, the greatest part of the solar energy that reaches the Earth is

　　 concentrated in the infrared spectrum

　　 concentrated at visible wavelengths

　　 absorbed by carbon dioxide molecules

　　 absorbed by atmospheric water vapor

　　 reflected back to space by snow and ice For the following question, consider each of the choices separately and select all that apply

　　4. According to the passage, atmospheric carbon dioxide performs which of the following functions

　　A absorbing radiation at visible wavelengths

　　B absorbing outgoing radiation from the Earth

　　C helping to retain heat near the Earths surface

　　答案：B/BC

　　以上即是阅读练习题，对于新gre考试逻辑阅读，考生除了采取题海战术，其实更应该做的就是总结。如果能从平日的练习中找到解新gre考试逻辑阅读题的思路，那么，要比采取题海战术更好。
