We can infer from the passage that the higher the lines are seen, the______ the images they present.
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 the societies in which we live. Many people believe, however, that our progress depends on different aspects of science. The first of these is the application of the machines, products and systems of applied knowledge that scientists and technologists develop. Through technology, science improves the structure of society and helps man to gain increasing control over his environment.
The second aspect is the application by all members of society 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 full of curiosity—he wants to find out how and why the universe works. He usually directs his attention towards problems which he notices have no satisfactory explanation, and his curiosity makes him look for underlining 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 applies logical thought to the observations he makes. He utilizes the facts he observes to the fullest extent. 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.
He is skeptical—he does not accept statements which are not based on the most complete evidence available—and therefore rejects authority as the sole basis for truth. Scientists always check statements and make experiments carefully and objectively to verify them.
Furthermore, he is not only critical of the works of others, but also of his own, since he knows that man is the least reliable of scientific instruments and that a number of factors tends to disturb objective investigation.
Lastly, he is highly imaginative 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 make hypotheses of how processed work and how events take place.
These seem to be some of the ways in which a successful scientist or technologist thinks and acts.
Many people believe that science helps society to progress through ______.
How men first learned to invent words is unknown; 【B1】 , the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain 【B2】 to express thoughts and feelings, actions and things, 【B3】 they could communicate with each other; and that later they agreed 【B4】 certain signs, called letters, which could be 【B5】 to represent those sounds, and which could be 【B6】 Those sounds, whether spoken, 【B7】 written in letters, we call words.
The power of words, then, lies in their 【B8】 —the things they bring up before our minds. Words become 【B9】 with meaning for us by experience; 【B10】 the longer we live, the more certain words 【B11】 to us the happy and sad events of our past; and the more we 【B12】 , the more the number of words that mean something to us 【B13】
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal 【B14】 to our minds and emotions. This 【B15】 and telling use of words is what we call 【B16】 style. Above all, the real poet is a master of 【B17】 He can convey his meaning in words which sing like music, and which 【B18】 their position and association can 【B19】 men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they will 【B20】 our speech or writing silly and vulgar.
