Which of the following statements about scientists is true?
A
Scientists tend to approach non-scientific problems in a more objective way than common people.
B
Most scientists believe arts and literature are of little use and hence think little of them.
C
Scientists are against the concept that science means a way of looking at the world partly for professional jealousy.

参考答案
参考解析
解析：
细节题。由第四段前两句的设问可排除A项。尾段第二句列举了一个化学家轻视文学和艺术的例子，但由此得出科学家们都认为文艺无用的观点属于过度推断，故B项错误。由最后一段所举例子可知，并不是所有的科学家都完全为政府服务，故D项表述过于绝对，可排除。文章第五段倒数第二句指出，科学是看待世界的一种方法，这一观点之所以遭到抵制完全是由于同行间的妒忌，作者在尾句又解释了自己这样认为的原因，故本题答案为C项。

As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use information in a different way.One of the world's great thinkers and scientists,Albert Einstein was dyslexic.Einstein said that he never thought in words the way that most people do.He said that he thought in pictures instead.The American inventor Thomas Edison was also dyslexic.Dyslexia first was recognized in Europe and the United States more than 80 years ago.Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are different.In most people,the left side of the brain一 the part that controls language is larger than the right side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this difference.However,research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.No one knows the cause of dyslexia,but some scientists believe that it may result from chemical changes in a baby's body long before it is born.They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help.After they have solved their problems with language,they often show themselves to be especially intelligent or creative.One out of five American children suffers from dyslexia.A:Right B:Wrong C:Not mentioned

There’s no doubt that nanotechnology promises so much for civilization. However, all new technologies have their teething problems, And with nanotechnology, society often gets the wrong idea about its capabilities. Numerous science-fiction books and movies have raised people’s fears about nanotechnology ---with scenarios such as inserting little nano-robots into your body that monitor everything you do without you realizing it,or self-replicating nano-robots that eventually take over the world.
So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and clear labelling. They believe that greater care should also be taken with nano-particles in laboratories and factories. Others have called for a withdrawal of new nano products such as cosmetics and a temporary halt to many kinds of nanotech research.
But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology.I really believe that most scientists would welcome a way to guard against unethical uses of such technology. We can’t go around thinking that all innovation is bad.all advancement is bad. As with the debate about any new technology.it is how you use it that’s important.So let’s look at some of its possible uses.
Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals. These could be virtually unbreakable, lighter and much more pliable leading to planes that are 50 times lighter than at present. Those same improved capabilities will dramatically reduce the cost of traveling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
In terms of technology, the computer industry will be able to shrink computer parts down to minute sizes. We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube. Nanotechnology could also revolutionise the way that we generate power .The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.
The author says that some scientists believe that nano-particles___A. should be used with more caution
B. Should be restricted to secure environments
C. Should only be developed for essential products
D. Should halt to do many kinds nanotech research

第三篇Scientific AttitudeWe all know that science plays an important role in our society.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一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（客观的）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 instmments and that a number of factors tend to disturb objective investigation.Lastly,he 15 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.What does the passage mainly discuss?A:Application of technology.B:Progress in modem society.C:Scientists,ways of thinking and acting.D:How to become a successful scientist.
