What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop.  The second is the application of the special methods of thought and action that scientists use in their work. 

What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

3.According to the passage, a successful scientist would NOT_______________.

A．easily believe in unchecked statements.

下面文章中有5处需要添加小标题。请从以下选项（A、B、C、D、E和F）中选出符合各段意思的小标题。选项中有一项是多余选项。

A. Kripke’s Research Tool

B. Dangers of Habitual Shortages of Sleep

C. Classification of Sleep Problems

D. A Way of Overcoming Insomnia

E. Sleep Problems of Long and Short Sleepers

F. Oversleeping — Too Much of a Good Thing

1. ______

Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences.

2. ______

Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers.

3. ______

Previous studies have shown the potential dangers of chronic(慢性的) shortages of sleep — for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.

4. ______

For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how mush they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having tiredness interfere with day-to-day functioning.

5. ______

Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bed. “It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake,” he said.
