  The transfer of heat and water vapor from the ocean
  to the air above it depends on a disequilibrium at the
  interface of the water and the air. 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.

对了一道，唉，考G初哥前来拜山，七月份考！在匹大考点！

两个都是A

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.

表层水体水温基本接近气温，近水体气体中水汽饱和，这种情况下基本无水汽和热量的交换。当上层空气较干、冷时会与水体近表层的空气发生涡旋对流。（根据常识推测：如果上层空气较干、热时（密度较小）应不会发生涡旋对流现象。）因此仅从文中信息不能推断E是正确的，答案E太绝对。

我想问一下，那个 速度为零后，E是怎样一刀砍死的？求指教！

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。

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：）

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~

普渡哥

楼上的，这两个都是单选：）
