阅读理解 A moment's drilling by the dentist 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 the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside it. This helps us adjust to the world. Without our nerves and our brain, 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 (酷刑) is based on the human body being open to pain.
But there is a way to handle pain. Some Indian monks can sit on a bed of nails. Fakirs (苦行僧)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 standing pain is our attitude toward 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(感觉) , we can handle the pain calmly. After all, although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.
