更多“Greater knowledge of the unive…”相关的问题
Today a student knows that__________
A．his knowledge is often incorrect
B．he cannot learn more than the students in the 19th century did
C．those who come after him will have greater difficulties in learning
D．his knowledge is very limited compared with the total amount
During the past 200 years the world population has increased 6 times, the annual world output has increased 80 times, and the distance a person can travel has gone up 1,000 times. There has also been much recent progress in art, culture, learning, and science. Such changes have led to a high rate of production and growth of the economy.
Economists fear that within the next 100 to 150 years, the earth's resources will become very scarce. Their fears are partly justified, but we should not be afraid. Industrial civilization adapts to new knowledge. By advancing knowledge, we not only create new forms of resources, but we also find ways to economize their use. Advanced modern knowledge can feed the hungry people of the world and improve their standard of living.
The figures in the second paragraph are used for the following purposes EXCEPT______.
A．prediction.
B．contrast.
C．definition.
D．explanation.
Here is a great argument in favor of foreign travel and learning foreign languages. It is only by traveling in, or living in a country and getting to know its inhabitants and their language that one can find out what a country and its people are really like. And how different the knowledge one gains this way frequently turns out to be from the second-hand information gathered from other sources! How often we find that the foreigners whom we thought to be such different people from ourselves are not very different after all!
Differences between peoples do, of course, exist and, one hopes, will always continue to do so. The world will be a dull place indeed when all the different nationalities behave exactly alike, and some people might say that we are rapidly approaching this state of affairs. With the much greater rapidity and ease of travel, there might seem to be some truth in this at least as far as Europe is concerned. However this may be, at least the greater ease of travel today has revealed to more people than ever before that the Englishman or Frenchman or German is not some different kind of animal from themselves.
Every country criticizes ways of life in other countries because they are______.
A．distorted
B．normal
C．similar to each other
D．different from its own

We can't judge every modern building by the standards of the ancient time, even though we admire the ancient buildings. Technologically, the modern buildings are more advanced. The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.
Some people hate everything that is modern because ______.
A．they are aged
B．they find it hard to accept modern things
C．they take their standards of perfection from the Greek
D．they look at things by the standards of the past
Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they
find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom
have a good word for the new buildings that are being built everywhere in the world. Such people look for
perfection in everything, and they take their standards of perfection from the past. They are usually impatient
with anyone who is brave enough to experiment with new or to express himself or the age in materials original
ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can
only be considered as failures. If the work of art is a painting, the artist’s failure concerns himself alone, but if
it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does
sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.

A major incentive (动力) for college attendance is the belief that it will prepare you for a career. Chances are that the career you want, whether in nursing, counseling, law, or management, requires a college education. Even if the return of your education isn't as great as it used to be, you would probably rather be a relatively poorly paid lawyer than a secretary or a construction worker: you would probably rather be a manager than a managee. In the sense that a degree is increasingly required for even middle-level jobs, your investment in a college education will still pay off.
It can pay off in other ways too. It is a value judgement to say that a college education will make you a better person, but it is a value judgement that the vast majority of college graduates are willing to make survey after survey to demonstrate that people feel very positive about their college education, believing that it has made them better and more tolerant people.
Whether it makes you a better person or not, a college education is likely to have a lasting effect on your knowledge and values. If you finish college, you will sit through 30 to 45 different courses. Even the least dedicated student is bound to learn something from these courses. In addition, students learn informally. Whether you go to college in you hometown or across the country, college will introduce you to a greater diversity of people than you ' re likely to have experienced before. This diversity will challenge your mind and broaden your horizons.
As a result of formal and informal learning, college graduates are more knowledgeable about the world around them, more tolerant and less prejudiced, more active in public and community affairs, and, more open to new ideas.
It is apparent from the passage that people go to college mainly because they believe
A．a college education will provide them with a guarantee of success in life
B．the economy of their country can't absorb an army of untrained youngsters
C．a college education will make them better qualified for a career
D．the investment in a college education can bring a higher economic return than before
So why is this huge increase in population taking place？ It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather different. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.
If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50,000 square meters. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the world's land cannot produce food.
Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital" — its nonrenewable fossil fuels and other mineral deposits that took millions of years to form. but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us.
It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.
According to the article, what contributes to the population increase？
A．Birth explosion.
B．Birth Control.
C．Technological innovations.
D．Death Control.

Questions 51 to 55 are based on the following passage.
Twenty years ago, the Urban Land Institute defined the two types of cities that dominated theUS landscape: smaller cities that operated around standard 9-5 business hours and largemetropolitan areas that ran all 24 hours of the day. Analyzing and comparing cities using thelens of this basic divide gives interesting context to how investment capital flows and housingprices have shifted.
In recent years, many mid-sized cities have begun to adopt a middle-of-the-road approachincorporating the excitement and opportunity of large cities with small cities&39; quiet aftermidnight. These 18-hour cities are beginning to make waves in real estate rankings and attractmore real estate investment. What is underlying this new movement in real estate, andwhy do these cities have so much appeal？
18-hour cities combine the best of 24-hour and 9-5 cities, which contributes to downtownrevitalization. For decades, many downtown cores in small to mid-sized cities were abandonedafter work hours by workers who lived in the suburbs. Movement out of city centers waswidespread, and downtown tenants were predominantly made up of the working poor. Thisgenerated little commerce for downtown businesses in the evenings, which made business andgenerating tax revenue for municipal upkeep difficult. With the rise of a new concept in urbanplanning that aims to make life easier and more convenient, however, increasing popularityfor urban areas that cased the real estate pushes, in major cities like San Francisco or NewYork, has inspired a type of forward thinking urbanity and in smaller cities.
Transforming downtown areas so that they incorporate modern housing and improvedwalkability to local restaurants, retail, and entertainment—especially when combined withimproved infrastructure for cyclists and public transit—makes them appeal to a more affluentdemographic. These adjustments encourage employers in the knowledge and talentindustries to keep their offices downtown. Access to foot traffic and proximity to transit allowthe type of entertainment-oriented businesses such as bars and restaurants to stay openlater, which attracts both younger, creative workers and baby boomers nearing retirementalike. Because of their smaller size, most keep hours that allow people to enjoy themselves, then have some quiet after midnight, as opposed to large major cities like New York, wherethe buzz of activity is ongoing.
These 18-hour cities are rapidly on the rise and offer great opportunities for homeownerinvestment. In many of these cities such as Denver, a diverse and vigorous economyattracted to the urban core has offered stable employment for residents. The right urban mixhas propped up home occupancy, increased property values, and attracted significantinvestment capital.
