What makes a person a scientist？ (是什么使一个人成为科学家？)Does he have ways or toolsof learning that are different from those of others？ The ans wer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time.He must be as nearly right as the conditions permit. What works under one set of conditions at onetime must work under the same must be explained by the changes in the conditions. This is one reasonthat investigations are important in science. Albert Einstein, who developed the Theory of Relativity,arrived at this theory through mathematics. The accuracy of his mathematics was later tested throughinvestigations, and Einstein ’idesas were shown to be correct. A scientist uses many tools formeasurements. Then the measurements are used to make mathematical calculations that may test his investigations.

Doctors have their own special sleep problems. Residents are famously short of sleep. It is not unusual for. them to work 40 hours in a row without rest. They are not in the least worried about it, confident they can still deliver the highest quality of medical care. But an article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person' s motor performance is comparable to that of someone who is drunk. Curiously, surgeons who believe that operating under the influence of alcohol is grounds for sacking often don' t think twice about operating without enough sleep.
"I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, which runs a website for residents. Some are terrifying." I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly planted my face into the wound."
"Practically every surgical resident I know has fallen asleep at the wheel driving home from work," writes another. "I know of three who have hit parked cars. Another hit a 'Jersey gate' on the New Jersey Expressway, going 105kin/h."
"Your own patients have become the enemy," writes a third, because they are "the one thing that stands between you and a few hours of sleep."
The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worded about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more rested staffers are available.
Sleep is a funny thing because ______.
A．the longer one sleeps, the less sound sleep he gets
B．the more sleep one gets, the more likely a stroke occurs
C．many people stick to about eight hours of sleep to stay fine
D．many people who sleep six hours a night still feel energetic in the day
Generally speaking, the harder one works, ______.
A．the better he gets result
B．the better result he gets
C．he gets better result
D．does he get better result
