    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.
【C3】
选项
答案G
解析 空格前的Another提示，此处填入名词。由上一段的One adaptation可知，此处讲的是沙漠动物获得的另一个减少炙热天气影响的适应特性。结合空格后的of large desert animals可知，填入的名词与与沙漠动物形成从属关系，strategy“战略，策略”符合语义。本句讲的是“沙漠中的大型动物适应环境的另一个策略就是……”。
