第一段：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 taken out.Today,however,we needn't worry about feeling of 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 his pain.
第二段　Long ago,operation 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.
　　第三段Soon after 1770,Joseph 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.
　　第四段Wells took some of the gas,and his friend pulled out one of Well's teeth.Wells felt no pain at all.
　　第五段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.

①.没有人在听到他的身体被外科医生切开并拿走了一部分器官之后还是开心的.但如今,我们不必为手术时的疼痛而担心.手术时,病人会陷入一种熟睡,而他醒来时,手术已经完成了.但这些令人开心的情况是全新的.这对于人们手术时会感觉到疼痛的年代相隔并不远.
②.很久以前,手术在病人能感知一切的时候展开,病人在手术时必须被压在手术台上.他能感觉到手脚被切断的痛苦,他撕心裂肺的叫声紧紧抓着手术时里每个人的心.
③.1770年后不久,Joseph Priestley 发现了一种叫“笑气”的气体.从那以后,笑气在美国流传.年轻男女去聚会上尝试.他们中的大多数都大笑着,只有一个人,Horace Wells,他发现人们在使用笑气的时候并没有感觉到疼痛.他决定在自己身上尝试.他请一个朋友帮助他.
④.他使用一些笑气,他的朋友则拔他的牙齿.但他没有感觉丝毫疼痛.
⑤.因为他并不完全了解笑气,他在另一个人身上使用了比自己使用时少一些的笑气.那个人在拔牙时明显感觉到疼痛并大喊了出来.他又试了一次,但这次,他给了足够多的笑气,而这个人死了.他永远忘不了这件糟糕的事.
