    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.
【C4】
选项
答案N
解析 空格前的be表明此处需要填入动词的过去分词形式或形容词。下一句提到骆驼失去占其体重高达30％的水分也不会对自身造成伤害，而人类丧失占体重12-13％水分就会死亡，由此可以推断，它们能够接受的失水程度对其他动物来说。是足以致命的。fatal“致命的”符合语义。
