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 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. 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. An interacting—and complicating—phenomenon is wind-to-water transfer of momentum that occurs when waves are formed. When the wind makes waves, it transfers important amounts of energy—energy that is therefore not available to provide turbulence.

20. 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.

我唯一能排除的就是D
答案是A
The air is mixed by means of turbulence that depends on the wind for its energy.
这句话不是说维持不平衡的因素是风，不平衡导致了saturated?

maintained, interface, content, however, depends

所以当差异不在时也就是no wind，millimeter water air 就会与水温相同并饱和。

这个文章前半段讲的静态情况下的"平衡"，后半段讲的起风就打破这种平衡进行热交换。
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.
这句话可以排除B,C,确定A
B,不是warmer错了，是close to
C,因为无风air is nearly saturated with water vapor，所以不是decrease,而是increase
As wind speed increases, so does turbulence, and thus the rate of heat and moisture transfer
这个排除D，无风没有进行热交换，所以increase错了
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.
这个排错E， air higher up是 cooler and lower，不是same
