问题     Human beings are animals. We breathe, cat end digest, and reproduce-the same life【71】common to all animals. In a biological laboratory, rats, monkeys, and humans seem very much the same.
    However, biological understanding is not enough:【72】itself, it can never tell us what human beings are.【73】to our physical equipment—the naked human body—we are not an【74】animal. We are tropical creatures,【75】hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us get it. In the purely physical【76】, our species seems a poor【77】for survival.
    But we have survived—survived and multiplied and【78】the earth. Some day we will have a【79】living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things? Part of the answer is physical.【80】its limitations, our physical equipment has some important【81】. We have excellent vision and hands that can【82】objects with a precision unmatched by any other【83】. Most importantly, we have a large brain with an almost【84】number of neural【85】.
    We have used this physical equipment to create culture, the key to our survival and success. If we live in the Arctic. we supply the warmth our tropical bodies need【86】clothing, shelter, and【87】heat. If a million people want to live in a desert that supplies natural food for only a few hundred, we find water to grow food and【88】deficits by transporting supplies from distant places. Inhabitants of our eventual moon colony will bring their own food and oxygen and then create an artificial earth environment to supply necessities. With culture, we can overcome our natural limitations.
    It was not always【89】. 0ur distant ancestors were just animals, faced with the limits of their physical equipment. They had no【90】and lacked the physical capacity to use it.  
选项 A、intellect
B、equipment
C、competence
D、culture
答案D
解析 语义搭配题。culture意为“文化”，文章反复提到人与动物的差别就在于人类有大脑创造的文化，with culture，we can overcome our natural limitations；此处淡到人类的祖先为什么还是动物，其原因应是缺乏文化，故选项D culture正确。其余选项：A intellect(智力)，B equipment(装备)和C competence(能力)均与题意不符。句意：不过，情况并非总是如此。当面对生理上的局限时，我们的远祖就只是动物。他们没有文化也没有可以利用文化的生理能力(即大脑)。
