GRE阅读题目解析:海洋与洋面上方空气

  P3

  1

  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.

  海洋与洋面上方空气存在一种热能与水蒸气的转移,这种转移取决于水与空气结合面的一种不平衡。

  (disequilibrium 不均衡,失调【 (ˌ)dis-ˌē-kwə-'li-brē-əm, -ˌe-kwə-】)

  2

  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.

  水面以上一厘米左右的空气,温度接近于水面,水蒸气也几乎达到了饱和。

  3

  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.

  这种差别尽管很小,却是至关重要的,而水面空气与更上方空气的混合,维持了这种不平衡状态,显然不难理解,上方的空气更冷,更干燥。

  4

  The air is mixed by means of turbulence that depends on the wind for its energy.

  不同强度的风造成了不同程度的扰动,使空气得以混合。

  5

  As wind speed increases, so does turbulence, and thus the rate of heat and moisture transfer.

  随着风速增加,扰动也变得更强烈,因此热量和湿度的转移速度也更快。

  6

  Detailed understanding of this phenomenon awaits further study. (127 words)

  这种现象的详细解释,需要更多研究。

  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.

  选 A

  A “使相对更冷,干燥的空气得以接近洋面”,正确项。

  B 错在不是 steady 的,根据句 5 ,风越大,rate 改变越大。

  C 造成海面水温的频繁变化。相当似是而非的干扰项,文中信息不足以得出这个结论。

  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.

  选 A

  A "最接近洋面的空气会达到水蒸气饱和",正确,见句 2 。

  B “最接近洋面的空气温度会高于水体”,高过水就见鬼了。

  C “水面附近空气的湿度会降低”,湿度不会降低,因为没有风,没有与上层空气的交换,湿度会一直维持在接近饱和的状态。

  D 说反了。

  E 根据句 3 的信息判断,上方空气较冷。
