Sharon Keating was worried about her kids when she got a divorce. Her daughter says, "I wa

s feeling... like down and sad and even though I did't really show it."

Judith Wallerstein says problems from divorce can last many years. They can show up when the kids are adults. And the kids have their own trouble. Wallerstein studied 93 children over a generation. The results can be found in her book.

She says that children of divorce are more likely to have problems with drugs. They are far more likely to seek therapy. About 40 percent of them avoid marriage themselves. When they do marry, fail at nearly twice the usual rate. It is hard for them to trust. They are afraid of failing.

Critics say Wallerstein had too few children in her study. They think that Wallerstein stresses too much from a small study. Other things may be the cause of the kid's problems. The study does not compare kids from divorced families with kids from "healthy" families.

Wallerstein's families divorced a generation ago. Times have changed. People feel different a bout divorce. Today programs like Kid's Turn try to reduce some of the effects of divorce with family advice. Talking about their feelings helps the kids get through it. Since they know more about the problems, maybe the kids will be able to handle it.

Which word can best describe the kids from divorced families according to Paragraph 1？

A．Offensive.

B．Relieved

C．Depressed

D．Prejudiced

Sylvester and I are watching television advertisements because we need information for

a class research project. We have to discuss realism and fantasy (幻想) in television advertising, and so we are looking for examples of distortions (歪曲) and falsehoods in television commercials. The question we are asking is, "Is the commercial true to life, or does it offer an unreal picture of the product？ "

Sylvester is keeping track of the distortions, and he already has quite a long list. He says that all housewives seem to live in lovely homes, dress beautifully, and love their household chores. They smile and boast about floor waxes and proudly display their dirty laundry, dusty tabletops, and filthy ovens. In addition, he has never seen men doing housework. Sylvester thinks that this view of family life is filled with distortions.I am keeping track of the people who appear in the advertisements. I have found handsome men courting the All-American Girl, and they are always recommending brand X toothpaste or brand Y cologne. I see teenagers and children surrounded by their friends, having wonderful times at parties and at school, and they are usually enjoying large harmonious family gatherings. I think that these advertisements are also filled with fantasy.Sylvester and I have concluded that much of American life is pictured unrealistically in commercials. Teenagers do not always have fun at parties, and very few people love doing chores. People do have problems, but few of these are ever shown in commercials. Instead, we watch Cinderella (灰姑娘) discover a miracle floor wax, finish the kitchen chores, and waltz off to the ball. Our heads are filled with these fantasies, and they also suggest that, for any problem, brand Z will provide the instant cure. Sylvester and I will have very few facts and a lot of fantasy to write about in our research reports.

1.Judging from the context, Sylvester and the author are most probably ____.

A、classmates

B、teacher and student

C、father and son

D、research workers

2.Sylvester has found that in advertisements housewives ____.

A、are sad and tired

B、enjoy doing their housework

C、have their husbands help them

D、never touch dirty things

3.The author thinks that life of teenagers shown in commercials is ____.

A、interesting

B、wonderful

C、unrealistic

D、true to life

4.Sylvester and the author have come to the conclusion that commercials ____.

A、truly reflect American life

B、lack in fantasy

C、seldom give expression to people's real problems

D、give great fun to children

5.The most suitable title for the passage would be ____.

A、A Class Research Project

B、American Life As Shown by TV

C、Beautiful Commercials

D、Distortions in TV Advertisements

第7题

Over the past few decades, there has been a considerable increase in the use of mathematic

al analysis, both for solving everyday problems and for theoretical developments of many disciplines. For example, economics, biology, geography and medicine have all seen a considerable increase in the use of quantitative techniques. Twenty years ago applied mathematics meant the application of mathematics to problems in mechanics and little else—now, applied mathematics, or as many people prefer to call it, applicable mathematics, could refer to the use of mathematics in many varied areas. The one unifying theme that these applications have is that of mathematical modeling, by which we mean the construction of a mathematical model to describe the situation under study. This process of changing a real life problem into a mathematical one is not at all easy, we hasten to add, although one of the overall aims of this book is to improve your ability as a mathematical modeler.

There have been many books written during the past decade on the topic of mathematical modeling; all these books have been devoted to explaining and developing mathematical models, but very little space has been given to how to construct mathematical models, that is, how to take a real problem and convert it into a mathematical one. Although we appreciate that we might not yet have the best methods for teaching how to tackle real problems, we do at least regard this mastery of model formulation as a crucial step, and much of this book is devoted to attempting to make you more proficient in this process.

Our basic concept is that applied mathematicians become better modelers through more and more experience of tackling real problems. So in order to get the most out of this book, we stress that you must make a positive effort to tackle the many problems posed before looking at the solutions we have given. To help you to gain confidence in the art of modeling we have divided the book into four distinct sections.

In the first section we describe three different examples of how mathematical analysis has been used to solve practical problems. These are all true accounts of how mathematical analysis has helped to provide solutions. We are not expecting you to do much at this stage, except to read through the case studies carefully, paying particular attention to the way in which the problems have been tackled—the process of translating the problem into a mathematical one.

The second section consists of a series of real problems, together with possible solutions and related problems. Each problem has a clear statement, and we very much encourage you to try to solve these problems in the first place without looking at the solutions we have given. The problems require for solution different levels of mathematics, and you might find you have not yet covered some of the mathematical topics required. In general we have tried to order them, so that the level of mathematics required in the solutions increase as you move through the problems. Remember that we are only giving our solutions and, particularly if you don't look at our solution, you might well have a completely different approach which might provide a better solution.

Here, in the third section, we try to give you some advice as to how to approach the tackling of real problem solving, and we give some general concepts involved in mathematical modeling. It must, though, again be stressed that we are all convinced that experience is the all-important ingredient needed for confidence in model formulation. If you have just read Sections I and 11 without making at least attempts at your own solutions to some of the problems set, you will not have gained any real experience in tackling real problems, and this section will not really be of much help. On the other hand, if you have taken the problem solving seriously in Section Ⅱ, you might find the general advice give

A．solving problems in real life with mathematics

B．the application of mathematics in problems related to mechanics

C．its ability to describe various situations

D．the construction of mathematical modeling

Mark went to the neighborhood meeting after work. The area's city councilwoman （女议员) wa

Mark went to the neighborhood meeting after work. The area's city councilwoman (女议员) was leading a discussion about how the quality of life was decreasing. The neighborhood faced many problems. People were supposed to suggest solutions to the councilwoman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here."

On his way back, Mark saw a woman carrying a grocery hag and baby. She was trying to unlock her car, but she didn't have a free hand. As Mark got closer, her other child, a little boy, suddenly darted into the street. The woman tried to reach for him, but as she moved, her bag shifted and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You've got great timing (适时) !"

"Just being neighborly (友好的) ," Mark said. As he rode home, he glanced at the walls of the bus passed by. On one of them was "Small acts of kindness add up." Mark smiled and thought, "Maybe that's a good place to start."

In the first paragraph, Mark thought that______.

A．nobody was so able as to solve these problems

B．many people were too selfish to think about others

C．he was not in the position to solve such problems

D．he already had more than enough work to do

Sleep is a funny thing. We're taught that we should get seven or eight hours a night, but

a lot of us get by just fine on less, and some of us actually sleep too much. A study out of the University of Buffalo last month reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke—probably as a result of an underlying disorder that keeps them from snoozing soundly.

Doctors have their own special sleep problems. Residents are famously sleep deprived. When I was training to become a doctor, it was not unusual to work 40 hours in a row without rest. Most of us took it in stride, confident we could still deliver the highest quality of medical care.

Maybe we shouldn't have been so sure of ourselves. An article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person's motor performance is comparable to that of someone who is legally intoxicated. Curiously, surgeons who believe that operating under the influence is grounds for dismissal often don't think twice about operating without enough sleep.

"I could tell you horror stories", says Jaya Agrawal, president of the American Medical Student Association, which runs a website where residents can post anonymous anecdotes. Some are terrifying. "I was operating after being up for over 36 hours", one writes. "I literally fell asleep standing up and nearly face planted into the wound".

"Practically every surgical resident I know has fallen asleep at the wheel driving home from work", writes another. "I know of three who have hit parked cars. Another hit a convenience store on the roadside".

"Your own patients have become the enemy", writes a third", because they are the one thing that stands between you and a few hours of sleep".

Agrawal's organization is supporting the Patient and Physician Safety and Protection Act of 2001, introduced last November by Representative John Conyers Jr. of Michigan. Its key provisions, modeled on New York State's regulations, include an 80-hour workweek and a 24 hour work-shift limit.

Most doctors, however, resist such interference. Dr. Charles Binkley, a senior surgery resident at the University of Michigan, agrees that something needs to be done but believes" doctors should be bound by their conscience, not by the government".

The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worried about the people treating you, you should feel free to ask how many hours of sleep they have had. Doctors, for their part, have to give up their pose of infallibility and get the rest they need.

Which of the following is NOT true according to the text？

A．In a recent scientific research, the scientists points out that someone who sleeps beyond the limit will probably not be in good health.

B．In the United States, the doctors usually do not take their sleep problems seriously.

C．Most doctors agree that the problems should be solved only by way of some compulsory means.

D．The U.S. government has already restricted the doctors' working hours.

第10题

We assumed ethics needed the seal of certainty, else it was non-rational. And certainty wa

s to be produced by a deductive model: the correct actions were derivable from classical first principles or a hierarchically ranked pantheon of principles. This model, though, is bankrupt.

I suggest we think of ethics as analogous to language usage. There are no univocal rules of grammar and style. which uniquely determine the best sentence for a particular situation. Nor is language usage universalizable. Although a sentence or phrase is warranted in one case, it does not mean it is automatically appropriate in like circumstances. Nonetheless, language usage is not subjective.

This should not surprise us in the least. All intellectual pursuits are relativistic in just these senses. Political science, psychology, chemistry, and physics are not certain, but they are not subjective either. As I see it, ethnical inquiry proceeds like this: we are taught moral principles by parents, teachers, and society at large. As we grow older we become exposed to competing views. These may lead us to reevaluate presently held beliefs. Or we may find ourselves inexplicably making certain valuations, possibly because of inherited altruistic tendencies. We may "learn the hard way" that some actions generate unacceptable consequences. Or we may reflect upon our own and others' "theories" or patterns of behavior. and decide they are inconsistent. The resulting views are "tested"; we act as we think we should and evaluate the consequences of those actions on ourselves and on others. We thereby correct our mistakes in light of the test of time.

Of course people make different moral judgments; of course we cannot resolve these differences by using some algorithm which is itself beyond judgment. We have no vantage point outside human experience where we can judge right and wrong, good and bad. But then we don't have a vantage point from where we can be philosophical relativists either.

We are left within the real world, trying to cope with ourselves, with each other, with the world, and with our own fallibility. We do not have all the moral answers, nor do we have an algorithm to discern those answers, neither do we possess an algorithm for determining correct language usage but that does not make us throw up our hands in despair because we can no longer communicate.

If we understand ethics in this way, we can see, I think, the real value of ethical theory. Some people talk as if ethical theories give us moral prescriptions. They think we should apply ethical principles as we would a poultice: after diagnosing the ailment, we apply the appropriate dressing. But that is a mistake. No theory provides a set of abstract solutions to apply straightforwardly. Ethical theories are important not because they solve all moral dilemmas but because they help us notice salient features of moral problems and help us understand those problems in context.

Ethical principles are generally thought to be ______.

A．explicitly clear

B．implicitly vague

C．certain but non-rational

D．relative but not subjective
