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
Line 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.

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

正确答案选 A，我选的AB

我当时选B的思路是这样的：
wind->disequilibrium->transfer of heat and water vapor
因此wind是维持heat and moisture transfer的原因。至于steady rate，文中用的是和B选项同样的词maintain，我觉得maintain本身就带有一点steady的色彩....

第二次看的时候又注意到这句，thus the rate of heat and moisture transfer. heat 和 moisture transfer可以理解，rate要怎么transfer？

求解答！

这题我也错了。文中原话是As wind speed increases, so does turbulence, and thus the rate of heat and moisture transfer. 这个thus=so，所以这里也是倒装句，说明transfer的速率是增加的，那么B就不对了，关键是increase这个词。
另外transfer的不是rate，heat and moisture transfer的整体来修饰rate，而不是分开
