谢谢斑竹！真是太感谢你了~！ 前几天连续生了两场大病，没怎么学习，虚度光阴了...... --------------------------------------------- -------------------------------------------- 做到PP1阅读最后一道题的时候，那个关于heat island的题目，最后一道题目（225）有争议，有人认为选择C，有人认为选择D 275. Which of the following is true about cities at night in the winter? C Less energy is required to heat buildings. D Human-made energy creates a larger area of total heat than solar energy. 选择C的人依据的是原文中的这句话 During the winter the nighttime warmth of urban areas, produced in large part by heavy energy consumption, is beneficial because less energy is needed to heat buildings 选择D的人依据的是这句话 Another study of the densely built-up Manhattan section of New York City revealed that during the winter the quantity of heat produced from combustion alone was two and one-half time greater than the amount of solar energy reaching the ground. 这里我觉得，答案应该是C。记得我的教授(研究气象的)讲关于太阳辐射的计算的时候提到过 solar energy 和solar radiation的概念，这里研究heat island的时候solar radiation一般被认为solar energy reaching the earth ground，一般研究太阳表面的总辐射量和研究地球环境美多大关系。所以D明显错误，因为D依据的文章也是说，greater than the amount of solar energy reaching the ground. 而D选项只是说Human-made energy creates a larger area of total heat than solar energy ETS真是狠毒，这种问题也出，没学习过的同学一疏忽可能会掉进陷阱里了.......汗，不知道我考试的时候会出什么题目，但愿理科的题目多一点....还有一周就考试了，每天除了阅读就是作文，时间还是很紧..... |
