阅读理解：
The world is not only hungry;it is also thirsty for water.This may seem strange to you,since nearly 75% of the earth's surface is covered with water.But about 97% of this huge amount is sea-water,or salt water.Man can only drink and use the other 3%——the fresh water that comes from rivers,lakes,underground,and other sources.And we cannot even use all of that,because some of it is in the form of icebergs（冰山）and glaciers（冰川）Even worse,some of it has been polluted.
The phrase"the world"in the first line of the passage refers to_____.
A."man"
B."you"
C."woman"
D."they"
正确答案：A
答案解析：第一句的深层意思是"人类不仅面临粮食危机,也面临水资源危机",因此"the world"代指"man"。我们也可以从本段第四句判断出来,它的主语是"man"。
