  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.

不知道啊：）我要问问。我觉得每日练还是定时发比较好：）

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。
