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 enou gh 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.

Astronauts have very busy lives. Each day they are carefully planned by mission(任务) control. The 12-hour working day on the International Space Station(ISS) begins with a wake-up call. After a quick wash with a wet cloth, the crew(全体乘务员) have breakfast and run through the jobs for the day.
Space stations are like large houses that need much care and attention. Much of the crew's time is spent preparing and carrying out scientific experiments.
At least two hours each day is spent on exercise. It is necessary to keep the crew healthy. In some ways, living in a space station is like being on a desert island. A crew of two or three astronauts has to survive far from home for weeks or months.
If their mission is to be a success, they have to learn to live and work together as a team. Crew members have to learn to share jobs such as cleaning and repairs. They also have to talk about problems and discuss how to deal with them.
Astronauts first feel the influence of weightlessness(失重) when the rocket engines are turned off. Straight away, they begin to float(漂浮), held down only by seat belts. Weightlessness allows astronauts to appear super strong. They can lift objects that would be far too heavy to move on the earth.
