    Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One adaptation is to be light in color, and to 【C1】______ rather than absorb the sun’s rays. Desert mammals also depart from the normal mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside the body, which would involve the expenditure of water and energy, desert mammals allow their temperatures to rise to what would normally be fever 【C2】______, and temperatures as high as 46 degrees Celsius have been measured in gazelles (瞪羚羊).
    Another 【C3】______ of large desert animals is to tolerate the loss of body water to a point that would be 【C4】______ for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, 【C5】______ human beings die after losing only 12 to 13 percent of then-body weight. An equally important adaptation is the ability to 【C6】______ this water loss at one drink. Desert animals can drink prodigious volumes in a short time, and camels have been known to 【C7】______ over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one 【C8】______, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse and far-flung pastures. Desert-adapted mammals have the 【C9】______ability to feed normally when extremely dehydrated;  it is a common experience in people that appetite is lost even 【C10】______ conditions of moderate thirst.
【C7】
选项
答案D
解析 空格位于不定式符号to之后，故应填入动词原形。本句的前半句说沙漠中的动物可以在很短的时间内喝进大量的水，结合空格后的over 100 liters可知此处需要填入一个跟drink词义相近的词。imbibe表示“喝，吸人”，尤指液体，符合句意。devour表示“狼吞虎咽地吃(食物，猎物)”，此处说的是喝水，故不选。
