1.Passage One

Global warming may or may not be the great environmental crisis of the 21 st century, but regardless of whether it is or isn ’t–w e won ’t do much about it. We will argue over

it and may even, as a nation, make some fairly solemn-sounding commitments to avoid

it. But the more dramatic and meaningful these commitments seem, the less likely they

are to be observed.

Al Gore calls global warming an “inconvenient truth, ” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don ’t know enough to relieve global warming, and –without major technological breakthroughs —we can ’t do much about it.

From 2003 to 2050, the world ’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total

energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. but

that ’s too low, because societies that grow richer use more energy. We need economic

growth unless we condemn the world ’s poor to their present poverty and freeze everyone else‘s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.

No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they ’r e “doing something. ”Consider the Kyoto Protocol (京都议定书 ). It allowed countries that joined to punish those that didn ’t. But it hasn ’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn ’t adopt tough enough policies to hit their 2008-2012 targets.

The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking dependence on fossil fuels or dealing with it.

The trouble with the global warming debate is that it has become a moral problem when

it ’s really an engineering one. The inconvenient truth is that if we don ’t solve the engineering problem, we ’re helpless.

57. What is said about global warming in the first paragraph?

A) It may not prove an environmental B) It is an issue requiring world wide crisis at all. commitments.

Passage Two

Someday a stranger will read your e-mail without your permission or scan the Websites you ’ve visited. Or perhaps someone will casually glance through your credit

card purchase or cell phone bills to find out your shopping preferences or calling habits.

In fact, it ’s likely some of these things have already happened to you. Who would

watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never

intended to be seen —the 21 st century equivalent of being caught naked.

Psychologists tell us boundaries are healthy, that it ’s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The

digital bread crumbs ( 碎屑 ) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple

Google search can reveal what you think. Like it or not, increasingly we live in a world

where you simple cannot keep a secret.

The key question is: Does that matter?

When opinion polls ask Americans about privacy, most say they are concerned about

losing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me. ”

But people say one thing and do another. Only a tiny fraction of Americans change

any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off

coupon (优惠券).

But privacy does matter –at least sometimes. It ’s like health: When you have it, you

don ’t notice it. Only when it ’s gone do you wish you ’d done more to protect it.

62. What does the author mean by saying “the 21 st century equivalent of being caught naked ”(Lines 3-4, Para.2)?

A) People ’s personal information is easily accessed without their knowledge.

B) In the 21 st century people try every means to look into others ’ secrets.

C) People tend to be more frank with each other in the information age.

D) Criminals are easily caught on the spot with advanced technology.

63. What would psychologists advise on the relationships between friends?

A) Friends should open their hearts to C) There should be a distance even each other. between friends.

B) Friends should always be faithful to D) There should be fewer disputes each other. between friends.

64. Why does the author say “we live in a world where you simple cannot keep a secret ”(Line 5, Para.3)?

A) Modern society has finally evolved into an open society.

B) People leave traces around when using modern technology.

C) There are always people who are curious about others ’ affairs.

D) Many search engines profit by revealing people ’s identities.

65. What do most Americans do with regard to privacy protection?

A) They change behaviors that might disclose their identity.

B) They use various loyalty cards for business transactions.

C) They rely more and more on electronic D) They talk a lot but hardly do anything devices. about it.

66. According to the passage, privacy is like health in that ________.

A) people will make every effort to keep it

B) its importance is rarely understood

There are many reasons for

D) people don ’t cherish it until they lose it

Passage1 Reading leadership literature, you’d sometimes think that everyone has the potential to be an effective leader. 读领导文学，你有时会认为每个人都有可能成为一个有效的领导者。 I don’t believe that to be true. In fact, I see way fewer truly effective leaders than I see people stuck in positions of leadership who arc sadly incompetent and seriously misguided about their own abilities. 我不相信这是真的。事实上，我认为真正有效的领导者的方式比我看到的人都陷在领导的职位上，遗憾的是他们自己的能力不称职，严重误导了他们。 Part of the reason this happens is a lack of honest self-assessment by those who aspire to（追求）leadership in the first place. 对产生这种现象的原因一部分是由那些渴望缺乏诚实的自我评估（追求）放在首位的领导 We've all met the type of individual who simply must take charge. Whether it's a decision-making session, a basketball game, or a family outing, they can't help grabbing the lead dog position and clinging on to it for dear life. They believe they're natural born leaders. 我们都遇到了个人的类型，他们必须负责。无论是决策会议，篮球比赛，还是家庭外出，他们都不能不抓住领导的狗的地位，并紧紧抓住它，因为亲爱的生命。他们相信他们是天生的领袖。 Truth is, they're nothing of the sort. True leaders don't assume that it's their divine（神圣的）right to take charge every time two or more people get together. Quite the opposite. A great leader will assess each situation on its merits, and will only take charge when their position, the situation, and/or the needs of the moment demand it. 事实是，他们没有什么样的。真正的领导者不认为这是他们的神圣（神圣的）负责每次两个或两个以上的人在一起吧。恰恰相反。一个伟大的领导者会对每一个情况进行评估，并在他们的位置、情况和/或需要的情况下，只会负责。 Many business executives confuse leadership with action. They believe that constant motion somehow generates leadership as a byproduct. Faced with any situation that can’t be solved by the sheer force of activity, they generate a dust cloud of impatience.

Unlike most, though, she decided to do something about it. Part declaration part record, her book Born to Rise writes down her journey toward creating and running her own system of progressive charter schools in Harlem in New York City. What is your educational philosophy? B) We want our students to receive the same high-quality education as students who are privileged to attend the best private schools in the country. Personally, I believe a progressive education is superior as long as it's delivered by really smart, talented teachers who know how to execute well. It's a sophisticated approach that really only works well in the hands of a really sophisticated educator. We're dealing with a little bit of a challenge because students enter this school from the regular public system. And when they enter in fifth grade, they're not yet well-trained in the basics reading, writing, and math--which means that we have to catch them up on basic math skills, on the 'basics of writing. And many of them come in at a kindergarten, first, second-grade level in reading. So we have to accelerate their mastery of the basics, but we reject the idea that if you do that you can't teach that at a high level. We push ourselves constantly to think about how we can make sure that our students will catch up while we teach at the highest possible

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body. Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it. 1.People are finding less and less time for relaxing themselves because_____. a.they do not know how to enjoy themselves b.they do not believe that relaxation is important for health c.they are travelling fast all the time d.they are becoming busier with their work 2.According to the writer ,the most important character for a good manager is his ________. a.not fearing stress b.knowing the art of relaxation c.high sense of responsibility d.having control over performance 3.Which of the follwing statements is ture? a.We can find some ways to avoid stress b.Stress is always harmful to people

大学英语四级阅读理解（1）We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming(把......按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning. In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyse and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher. Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently. An advanced pupil can do advanced work: it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every

洛基英语，中国在线英语教育领导品牌 综合题，请根据题目给出的内容，来回答下面给出的试题。We might marvel at the progress made in every field of study, but the methods of testing a person's knowledge and ability remain as primitive as ever they were. It really is extraordinary that after all these years, educationists have still failed to device anything more efficient and reliable than examinations. For all the pious claim that examinations text what you know, it is common knowledge that they more often do the exact opposite. They may be a good means of testing memory, or the knack of working rapidly under extreme pressure, but they can tell you nothing about a person's true ability and aptitude. As anxiety-makers, examinations are second to none. That is because so much depends on them. They are the mark of success of failure in our society. Your whole future may be decided in one fateful day. It doesn't matter that you weren't feeling very well, or that your mother died. Little things like that don't count: the exam goes on. No one can give of his best when he is in mortal terror, or after a sleepless night, yet this is precisely what the examination system expects him to do. The moment a child begins school, he enters a world of vicious competition where success and failure are clearly defined and measured. Can we wonder at the increasing number of 'drop-outs': young people who are written off as utter failures before they have even embarked on a career? Can we be surprised at the suicide rate among students? A good education should, among other things, train you to think for yourself. The examination system does anything but that. What has to be learnt is rigidly laid down by a syllabus, so the student is encouraged to memorize. Examinations do not motivate a student to read widely, but to restrict his reading; they do not enable him to seek more and more knowledge, but induce cramming. They lower the standards of teaching, for they deprive the teacher of all freedoms. Teachers themselves are often judged by examination results and instead of teaching their subjects, they are reduced to training their students in exam techniques which they despise. The most successful candidates are not always the best educated; they are the best trained in the technique of working under duress. The results on which so much depends are often nothing more than a subjective assessment by some anonymous examiner. Examiners are only human. They get tired and hungry; they make mistakes. Yet they have to mark stacks of hastily scrawled scripts in a limited amount of time. They work under the same sort of pressure as the candidates. And their word carries weight. After a judge's decision you have the right of appeal, but not after an examiner's. There must surely be many simpler and more effective ways of assessing a person's true abilities. Is it cynical to suggest that examinations are merely a profitable business for the institutions that run them? This is what it boils down to in the last analysis. The best comment on the system is this illiterate message recently scrawled on a wall: 'I were a teenage drop-out and now I are a teenage millionaire.' 请根据上面给出的内容，来回答下面的单项选择题（下列每小题备选答案中，只

3 大学英语四级阅读理解试题及答案（四） 十六 Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way. First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air. One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly. 1.Pruning should be done to ______. a.make the tree grow taller
