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

2.Long ago, when the sick man was operated on, he could feel nothing.
3.Using the laughing gas, the people seemed to feel pain during the operation.
