     No one is glad to hear that his body has to be cut open by a surgeon(外科医生) and part of it is taken

out. Today, however, we needn't worry about feeling pain during the operation. The sick person falls into

a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new.

It is not many years since a man who had to have an operation felt all its pain.

     Long ago, operations had usually to be done while the sick man could feel everything. The sick man

had to be held down on a table by force while the doctors did their best for him. He could feel all the pain

if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.

     Soon after 1770, Josept Priestley discovered a gas which is now called "laughing gas". Laughing gas

became known in America. Young men and women went to parties to try it. Most of them spent their time

laughing, but one man at a party, Horace Wells, noticed that people didn't seem to feel pain when they

were using this gas. He decided to make an experiment on himself. He asked a friend to help him.

     Wells took some of the gas, and his friend pulled out one of Well's teeth. Wells felt no pain at all. As

he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out

with pain when his tooth was being pulled out.

     Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this

terrible event.
