问题     A moment’ s drilling by the dentists may make us nervous and upset. Many of us cannot stand pain. To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle" that deadens the nerves around the tooth.
    Now it’ s true that human body has developed millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves — and our brain, which is a bundle of nerves — we wouldn’ t know what’ s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.
    But there is a way to handle pain. Look at the Indian fakir who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.
    The big thing in withstanding pain is our attitude towards it. If the dentist says, "This will hurt a little”, it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.
" We pay for our sensitivity" (Paragraph 2)means ________.

选项 A、it was fortunate for humans to have developed this sensitivity
B、we suffer because of this sensitivity
C、we know very well how to cope with sensations of pain
D、we have to pay the dentist for his treatment of our teeth

答案B

解析 第二段前三句:“人体的成百上千万个神经对内、外部世界保持高度警觉并随时做出调整,而没有一束束的神经组织,我们便无法感知周遭世界。”这种感觉当然包括对各种疼痛的感觉,故有此结论,其含义相当于B。
