68. GWD27-Q22
Whales originated in the freshwater lakes and rivers of ancient Asia about sixty million years ago. Not until about ten
million years later did species of whales develop specialized kidneys enabling them to drink salt water. Although fossil
evidence shows that some early whale species that lacked such kidneys sometimes swam in the Earth’s saltwater oceans,
these species must have had to return frequently to freshwater rivers to drink.
Which of the following is most strongly supported by the information given?
A. Fossils of whale species dating from between sixty million and fifty million years ago will not be found on
continents that were at the time separated from ancient Asia by wide expanses of ocean.
B. Among whale fossils that date from later than about fifty million years ago, none are fossils of whale species
that drank only fresh water.
C. Fossils of whale species that drank fresh water will not be found in close proximity to fossils of whale species
that drank salt water.
D. The earliest whales that drank salt water differed from fresh-water-drinking whales only in their possession of
specialized kidneys.
E. Between sixty million and fifty million years ago, the freshwater lakes and rivers in which whales originated
were gradually invaded by salt water.

鲸鱼起源于古代亚洲的淡水湖泊和河流的约六十亿年前。直到大约十
亿年后的鲸类制定专门肾脏，使他们能够喝盐水。虽然化石
证据表明，一些早期的鲸类，缺乏如肾脏，有时在地球的咸水海洋游，
这些物种必须有经常返回到淡水河流喝。
下列哪项是最强烈的支持所提供的资料？
A.可以追溯到第六十二亿五千万年前的鲸鱼物种的化石上找不到
从古老的亚洲广袤的海洋，当时的大洲分隔。
B.在鲸鱼化石，日期最迟约五十亿年前，没有鲸类化石
喝了新鲜的水。
C.喝淡水鲸类的化石将不会被发现在接近鲸类化石
喝盐水。
D.喝咸水的最早的鲸鱼不同于只有在他们身上的淡水饮用水鲸
专门的肾脏。
五至第六十二亿五千万年前，淡水湖泊和河流中，鲸鱼的起源

因为如果有大洋相隔，鲸鱼就不能返回到陆地区喝淡水了。。。
