Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.
This book is written for the intelligent student or lay person whose acquaintance with science is superficial; 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 gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.
We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.
We have also tried to make the book entertaining as well as informative. Our approach 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 grim and dreary way to earn a living.

Science is a dominant theme in our culture. Since it touches almost every aspect of our life, educated people need at least some idea of its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to obtain if one knows something about the things that excite and frustrate the scientist.
This book is written for the intelligent student or lay (外行) person whose knowledge of science is superficial; 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 small devices; and for the person who views the scientists as some sort of magician.

We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do.

This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all parts of society as more women enter traditionally male-dominated fields and make significant contributions.
In discussing these changes and contribution, however, we are faced with a language that is somewhat sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To balance this built-in bias (倾向), we have adopted the policy of using plural nouns and pronouns whenever possible and , when absolutely necessary, alternating him and her.

With rapid advances in medical science, cloning is slowly but surely looking like it could be in our near future. However, is it really an option that should be considered as a way to extend human life?
Reproductive cloning may help human families gain children, but there's also a benefit for the animal world. It brings hope to people eager for children but unable to have their own or adopt. It can also bring about the recreation of species that have long since died, allowing scientists to fully study the species as a living creature instead of simply looking at images or bones.
Many believe that cloning can be used to replace failing organs. This will reduce the waiting list for organ donations and allow more people to be saved. Not only that, but because the organ is, in fact, your own organ, there would be less chance of rejection.
Cloning could prove helpful in genetic research. Using cloning technologies, genetic researchers would have a better understanding of the composition of genes and the effects of genetic constituents (成分) on human characters. There's also the possibility of changing genetic constituents in cloned humans, and cloning could help fight genetic diseases.
While the cloning of body organs can help extend human life, it could also cause a lot of malpractice (玩忽职守). Along with the ability to clone desired characters, there could be the possibility of people deliberately reproducing undesired characters. This could lead to a rise in malpractices within society.
Cloning involves a process of creating identical genes. As such, there would be a lack of diversity in humankind. Scientists believe this lack of diversity will lower the human race's ability to adapt.
Whatever your view on cloning may be, studies show that the clone would in fact not be completely identical to the original just as twins are not completely identical. Though they might look alike, twins have different personalities and enjoy different things. The same could be said of clones. Even if technology were created in which your memories and thoughts could be transmitted (传送) to the clone, your clone would still be a different person.
1.What good might reproductive cloning bring?
A. It may help improve human well-being.
B. It could contribute to the rising birthrate.
C. It could help animals survive deadly diseases.
D. It may enable scientists to better study extinct species.
2.According to the text, cloning can also be used for ________________________________________________.
A. organ transplant
B. solving the aging problem
C. infectious disease treatment
D. constructing a gene database
3.What's one problem cloning may cause?
A. Great diversity.
B. Individual security risk.
C. Increased improper conduct.
D. Serious personality disorder.
4.Why are twins mentioned in the last paragraph?
A. To stress twins' similarities.
B. To show twins are quite common.
C. To carry out deeper research on twins.
D. To better illustrate what a clone will be like.
高三英语阅读理解中等难度题查看答案及解析
Uncertainty spreads through our lives so thoroughly that it dominates our language. Our everyday speech is made up in large part of words like probably, many, soon, great, little. What do these words mean?Such verbal expression is not necessarily to be criticized. Indeed, it has a value just because it allows us to express judgments when a precise quantitative statement is out of the question.
We have been trying to pin down by experiments what people mean by these expressions in specific contexts, and how the meanings change with age. For instance, a subject is told “There are many trees in the park” and is asked to say what number the word many mean to him. Or a child is invited to take “some” sweets from a bowl and we then count how many he has taken. We compare the number he takes when he is alone with the number when one or more other children are present and are to take some sweets after him, or with the number he takes when told to give “some” sweets to another child.
First, we find that the number depends, of course, on the items involved. To most people some friends means about five, while some trees means about twenty. However, unrelated areas sometimes show parallel values. For instance, the language of probability seems to mean about the same thing in predictions about the weather and about politics: the expression “is certain to” (rain, or be elected) signifies to the average person about a 70 percent chance; “is likely to”, about a 60 percent chance; “probably will” about 55 percent.
Secondly, the size of the population of items influences the value assigned to an expression. Thus, if we tell a subject to take “a few” or “ a lot of” glass balls from a box, he will take more if the box contains a large number of glass balls than if it has a small number. But not proportionately more: if we increase the number of glass balls eight times, the subject takes only half as large a percentage of the total.
Thirdly, there is a marked change with age. Among children between six and fourteen years old, the older the child, the fewer glass balls he will take. But the difference between a lot and a few widens with age. This age effect is so consistent that it might be used as a test of intelligence.
1. What’s the right attitude towards the words like probably, many, soon?
A. They are inaccurate and we should avoid them.
B. They are necessary since we cannot be always precise.
C. They should be criticized because there are too many of them.
D. Their value is not yet clear since we don’t know their meaning.
2. Why do we do experiments with the words “many” and “some”?
A. To prove people are insensitive to these words.
B. To prove the words dominate our everyday speech.
C. To find out how the meanings vary with age and contexts.
D. To find out whether the words can mean a precise quantity.
3. Which of the expressions means a larger chance in weather broadcast?
A. Possible B. Probable C. Be likely to D. Be certain to
4. Which of the following will least definitely influence the number of items a kid takes out of a box when he is invited to take “some”?
A. Whether the quantity of items is large or small.
B. Whether the items are candies or toys.
C. Whether the kid is a toddler or a youngster.
D. Whether the kid is alone or accompanied by other children.
5. What will tell us about the intelligence of a child?
A. The consistency of picking up a certain glass ball.
B. How many glass balls he will take when he’s asked to.
C. The difference between a lot and a few when he takes glass balls.
D. Whether there are marked changes in his first pick and second one.

In our comparisonsoaked (攀比成风的) culture, it's hard to avoid slipping into “Why can't I?” mode. When one of my colleagues who I think is not better than me published a new book, I couldn't help complaining how unachievable it seemed to me and what bad luck I had. Negative feelings like this made life dark for us. 1. Here's what I learned:
Don't compare your insides to someone else's outsides.
The first time I heard this excellent advice, I was suffering from terrible envy. My professor's warning shocked me that “You have no idea what it took for them to get there. Don't just owe it to pure luck. 2.”
She was absolutely right, yet it's much easier to envy what they've got than to ask the serious questions: What are they modeling for me? What have they done to get where they are today? 3.
Transform comparison into celebration.
Admiration and envy are responses pointing us toward what we value most. 4. If you notice yourself admiring people who take creative risks, bring your full attention to the part of you that wants to be braver.
_5.
Next time you catch yourself admiring or envying someone's success, take a moment to consider: What qualities in them inspire me? Where do I presently display these qualities? Remember the light we see in others can help us see our own!
A.Use the success of others as a mirror.
B.Learn to appreciate others' shining points.
C.How to get rid of the harmful effects of comparison needs exploring.
D.However, there is no doubt that good luck can't be ignored.
E.Instead, you should find out what's really going on behind the scenes.
F.And once we become aware of what we value, we are much better positioned to create a richly satisfying life.
G.When we reflect on these questions, we shift immediately out of comparison mode and turn inwards.

One of the most widely accepted, commonly repeated assumptions (假设) in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have got fat that hangs over my belt when I sit. Why isn’t all the exercise getting rid of it?
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly.
And yet obesity (肥胖) figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated.
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or from magazines like this one.
1. From the passage we learn that ____.
A. some Americans join a health club but never go there
B. the number of overweight people has doubled since 1993
C. more than 45 million Americans now go to the gym regularly
D. Americans waste too much money each year on sports
2. According to the passage, exercise ____.
A. has long been believed to be good for older adults
B. is not properly advertised as an effective way to lose weight
C. was first recognized as an effective way to lose weight in the 1960s
D. is less effective in preventing heart disease than what doctors believe
3. According to the writer, people might gain weight because ____.

B. they eat the same food when they do not exercise
C. they exercise less than required by doctors
D. they eat more after they exercise

The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can make one hungry. That causes us to eat more, which in turn can negate (使无效) the weight-loss benefits we just gained. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.
