Within about a millimeter of the water, air temperature is close to that of 5 the surface water, and the air is nearly saturated with water vapor. But the differences, however small, are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water-vapor content. 10 The air is mixed by means of turbulence that depends on the wind for its energy. As wind speed increases, so does turbulence, and thus the rate of heat and moisture transfer. Detailed understanding of this phenomenon awaits further study. (127 words)
For the following question, consider each of the choices separately and select all that apply 7. According to the passage, wind over the ocean generally does which of the following? □A Causes relatively cool, dry air to come into proximity with the ocean surface. □B Maintains a steady rate of heat and moisture transfer between the ocean and the air. □C Causes frequent changes in the temperature of the water at the ocean‘s surface.
8. The passage suggests that if on a certain day the wind were to decrease until there was no wind at all which of the following would occur? (A) The air closest to the ocean surface would become saturated with water vapor. (B) The air closest to the ocean surface would be warmer than the water. (C) The amount of moisture in the air closest to the ocean surface would decrease. (D) The rate of heat and moisture transfer would increase. (E) The air closest to the ocean would be at the same temperature as air higher up.作者: Liam0205 时间: 2011-9-23 08:12

不知道啊：）我要问问。我觉得每日练还是定时发比较好：）作者: Liam0205 时间: 2011-9-23 08:35
文章说的是，ocean和上面air的heat还有water vapor的交换——实际上就是风的事情。
T7, 说了这个Wind就是上面的交换。 But the differences, however small, are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water-vapor content. 果断扑倒A。
T8， As wind speed increases, so does turbulence, and thus the rate of heat and oisture transfer. no wind，就是speed = 0. 一刀砍死BCDE。 选A。作者: Liam0205 时间: 2011-9-23 08:37

有时候早上有课啊，看不到，不如每天多发几篇``然后晚上晚点公布答案~作者: 普渡哥 时间: 2011-9-23 10:55
可以考虑。我就怕发多了没人做。我过阵子看情况好改成一日两篇：）作者: lemonade88 时间: 2011-9-23 11:06

这是ｌｉａｍ同学提供的正确答案和解题步骤，供大家参考： T7, 说了这个Wind就是上面的交换。 But the differences, however small, are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water-vapor content. 果断扑倒A。
T8， As wind speed increases, so does turbulence, and thus the rate of heat and oisture transfer. no wind，就是speed = 0. 一刀砍死BCDE。 选A。作者: gracesrm 时间: 2011-11-2 18:19
我想问一下，那个 速度为零后，E是怎样一刀砍死的？求指教！作者: xinjunz 时间: 2011-11-10 00:03
至于E是如何干掉的，我觉得可以这样理解，关键是这段： Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor. But the differences, however small, are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water-vapor content.
