42.According to the passage.which of the following is TRUE? A.People would contract the A/H1N1 flu if they often eat pork. B.The virus of the A/H1N1 flu has infected people all over the world. C.People from A/H1N1 flu-hit countries are all forbidden to enter China. D.People should avoid visiting places where A/H1N1 flu cases have been reported. C Science is a major topic in our culture. Since it touches almost every field of our life, educated people need at least some knowledge with its structure and operation. They should also have an understanding of the scientific subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific ideas is easier to obtain if one knows something about the things that excite and discourage the scientist. This book is written for the person whose knowledge with science is not complete; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of tricks; and for the person who views the scientists as some sort of magician. The book can be used to add to a course in any science, to come with any course that attempts to give an understanding of the modern world, or simply to provide a better understanding of science. We hope this book will lead readers to a broader view on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an idea and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. Besides, readers may learn to appreciate the relationship between scientific views and some of the values and philosophiesthat are deep in our culture. We have tried to present in this book a correct and up-to-date picture of the scientific world and the people who populate it. That population has in recent years come to include more and more women. This increasing role of women is not just the only event but, rather, part of the trend obvious in all parts of society, as more women enter traditionally male-controlled fields and make influential contributions. We have also tried to make the book entertaining as well as informative. Our method is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a cruel and unpleasant way to earn a living. 43 According to the passage, `scientific subculture’ means . A. scientific society B. technical groups C. complex situation D. knowledge system 查看更多

 

题目列表(包括答案和解析)

Few people would question the value of taking part in sports for young people.With proper training,supervision,protective equipment and techniques,and an proper emphasis on winning,sports can develop a healthy body and spirit and a life-long interest in being active and fit .Without such measures,childhood sports can lead to injuries and even paralysis or death.

Even in the best conditions,no activity can be risk—free.But most serious hazards are preventable.Cyclists and football players can reduce their risks by wearing helmets;hockey players by wearing masks;basketball and tennis players by wearing eye guards;baseball players by wearing batting helmets.

Besides,risks to individual players can often be found,and thus prevented,through a properly performed medical exam before a child plays.For accidents that may not be preventable,having an emergency plan and first-aid equipment,and someone trained to use the equipment,can be lifesaving.

Still,each year,according to the American College of Sports Medicine,more than 775,000 children under 14 are treated in emergency rooms for sports injuries,nearly half of them preventable.An estimated 300,000 athletes experience exercise—related head illnesses each year,and almost all of them should have been avoided.

Further,from half to three—fourths of sports-related concussions(脑震荡) are never even diagnosed;the injured are often sent back in to play too soon and put at risk of another more serious brain—damaging concussion.To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www.SportsSafety.org.
