Question

The Antarctic Icecap is the largest supply of fresh water，representing nearly 2％of the world’s total of fresh and salt water. As can be seen from the table below, the amount of water in our atmosphere is over 10 times as much as the water in all the rivers taken together. The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1％of the world’s total water supply.

	Surface area(sq mi)	Volume(cu mi)	Percentage of total
Salt water
The oceans	139,500,000	317,000,000	97.2％
Inland    seas    and saline lakes	270,000	25,000	0.008
Fresh water
Freshwater lakes	330,000	30,000	0.009
All rivers(average level)	－	300	0.0001
Antarctic Icecap	6,000,000	6,300,000	1.9
Arctic Icecap and glaciers	900,000	680,000	0. 21
Water in the atmosphere	197,000,000	3,100	0. 001
Ground water within half a mile from surface a mile from surface	－	1,000,000	0. 31
Deep-lying ground water	－	1,000,000	0. 31
Total (rounded)	－	326,000,000	100.00

5.C

【解析】

试题分析：本文本文讲述了世界水资源的分布情况，以及淡水和海水的具体的百分比情况，并详细说明了各种水资源所占的比例等数据。

1.B 主旨大意题。本文讲述了世界水资源的分布情况，以及淡水和海水的具体的百分比情况，故本文是关于世界水供应的话题，B项正确。

2.D 细节题。根据表格3，4行说明海里的海水和内陆湖泊的水一共占据了世界水资源的百分之98，故D项正确。

3.A 计算题。根据第一段最后2行The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1％of the world’s total water说明可以饮用的淡水只占全世界水含量的one-third of 1％而全世界水含量是326,000,000，故大约有1,086,700。A项正确。

4.C 细节题。根据文章1,2行The Antarctic Icecap is the largest supply of fresh water，representing nearly 2％of the world’s total of fresh and salt water说明The Antarctic Icecap才是最大的淡水存在的地方，故C正确。

5.C 细节题。根据表格倒数2,3行的Ground water within half a mile from surface and Deep-lying ground water.的水量基本相同，故C项正确。
