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.
正确答案是A，我怎么觉得在有风或者没风的情况下都是A呀，当然BCDE都不对，也只能选A,只是有些牵强，还请高人指点！

“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“
后面说风可以促进这种turbulence
取非得A..

ps. 做了太久了..只好回去找下原文
