    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.

    1.Which of the following statements about a curious scientist is TRUE?

    A. He doesn’t find confidence and pleasure in work.

    B. He is interested in problems that are explained.

    C. He makes efforts to investigate potential connections.

    D. He looks for new ways of acting.

    2.According to the passage, a successful scientist would NOT______.

    A. easily believe in unchecked statements.

    B. easily criticize others' research work.

    C. always use his imagination in work.

    D. always use evidence from observation.

    3.Which word can be used to describe the data that a good scientist uses?

    A. complete B. concrete

    C. complicated D. confusing

    4. What does the passage mainly discuss?

    A. Application of technology.

    B. Progress in modern society.

    C. Successful scientists' ways of thinking and acting.

    D. How to become a successful scientist.

    科目：高中英语 来源：2016届重庆巴蜀中学高三上学期第三次月考英语试卷（解析版） 题型：阅读理解

    Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.

    An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.

    However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.

    In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible?

    Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents—today’s grandparents—would have called their children more often if the means and cost of doing so had not been a barrier.

    Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

    Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

    1.The surveys inform us of______.

    A. the development of technology

    B. the changes of adult children’s behavior

    C. the parents’ over-protection of their college children

    D. the means and expenses of students’ communication

    2. The writer believes that__________.

    A. parents today are more protective than those in the past

    B. the disadvantages of new technology outweigh its advantages

    C. technology explains greater involvement with their children

    D. parents’ changed attitudes lead to college children’s delayed independence

    3.What is the best title for the passage?

    A. Technology or Attitude

    B. Dependence or Independence

    C. Family Influences or Social Changes

    D. College Management or Communication Advancement

    4.Which of the following shows the development of ideas in this passage?

    Five Simplification Steps to Experiencing Happiness

    Happiness is never a permanent condition; it is made up of individual conditions that give rise to happiness. The Hungarian-American psychologist Mihaly Csikszentmihalyi calls this condition “flow”: becoming so absorbed in an activity that nothing else seems to matter. You cannot manufacture happiness — but you can prepare the soil for happiness to grow. Researchers have found the following five qualifications in their studies of happy people.

    1.______ Your working environment has a major influence on your experience of happiness. If you are surrounded by staff who grumble and have a negative attitude, it will be much more difficult for you to experience flow than it would be on a harmonious team. Identify clearly which people in your working environment suffer from chronic unhappiness and might infect you with it on an unconscious level. Keep a greater distance from those people or ask for a transfer.

    2.____ People who have to devote their attention to several activities at once are unable to get into the flow. You will be able to experience those moments of happiness only when you engage in an activity with your whole being.

    3._____ People who experience flow have managed to turn the restrictions of their working environment into opportunities. They see themselves as the criterion (标准) for their quality. Recognition from others or money they earn recede into the background. Among the people who Csikszentmihalyi discovered to be experiencing the greatest degree of happiness, there was a very simple worker in a steel mill who was popular with everyone on account of his specialized knowledge and willingness to help.

    4.______ People who feel like victims and don’t live but “are lived” lose their ability to enjoy themselves even if their work is exemplary. So change your job, even if the new one doesn’t pay as well or is less prestigious (有声望的) . People who find happiness in their work will work so well that sooner or later they will profit, even on the level of money and prestige.

    5.______ Astonishingly, work is easier to enjoy than free time. Working life includes goals, rules, and challenges. On the other hand, free time is unstructured and it takes effort to organize it in such a way as to make it enjoyable. So don’t be reluctant to plan your free time and structure it deliberately. People who don’t waste their free time have a more positive awareness of life; they live longer and they are less often sick. However, people who spend their time at work looking forward eagerly to going home and to the weekend seldom experience flow. Only 18% of all those questioned by Csikszentmihalyi experienced flow in the context of free time, and in almost all cases where they did, it was in the context of an organized hobby.
