听力原文:The private motor vehicle has given us a freedom our ancestors could not dream ab

听力原文: The private motor vehicle has given us a freedom our ancestors could not dream about. We can travel swiftly, and usually safely, over the roads which have been built to accommodate our cars. People can display their wealth by driving a car which may cost as much as another person's home.

(29) Sadly the car has become a disadvantage as well as a boon. The car pollutes the atmosphere, may be involved in serious accidents, and by its very numbers blocks roads. (29) How can we reduce its use? The car is only desirable if we can use it easily, so we might begin by reducing access to parking spaces in the cities and simultaneously increasing the quality and availability of public transport. Cars could be banned from certain parts of the city, thus forcing people to walk or to use public transport. The expense of buying and running a car can be raised. (30) If the motorist is faced with a high purchase price, high road tax, high insurance premiums and substantial fines he or she may reconsider the purchase. A corresponding reduction in the price of public transport would help this financial argument against car ownership.

Neither of these arguments will sway the super rich who can afford the status cars, but it would perhaps encourage them to look at other ways of demon-strafing their wealth. (31) However we do it, reducing the number of cars on the road will reduce the problems of pollution and the congestion which can bring cities to a standstill.

29. What does the speaker focus on?

30.What factor might hinder most people's consideration of purchasing private cars?

31.What would be the result if the number of private cars is reduced?

(4)

A.The sadness of being involved in accidents.

B.Ways to limit the use of private cars.

C.The serious pollution on motor roads.

D.Freedom to travel quickly and safely.

Questions 26 to 30 are based on the following passage. The question of whether war is inev
itable is one which has concerned many of the world’s great writers. Before considering this question, it will useful to introduce some related concepts. Conflict, defined as opposition among social entities directed against one another is distinguished from competition, defined as opposition among social entities independently striving for some thing which is in inadequate supply. Competitors may not be aware of one another, while the parties to a conflict are. Conflict and vice of one another.

Opposition is thus contrasted with cooperation, the process by which social entities function in the service of one another. These definitions are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited resources, but conflict is not. Conflict, nevertheless, is very likely to occur, and is probably an essential and desirable element of human societies.

Many authors have argued for the inevitability of war from the premise that in the struggle for existence among animal species, only the fittest survive. In general, however this struggle in nature’s competition, not conflict. Social animals, such as monkeys and cattle, fight to win or maintain leadership of the group. The struggle for existence occurs not in such fights but in the competition for limited feeding areas and for the occupancy of areas free from meet-eating animals. Those who fail in competition starve to death or become victims to other species. This struggle for existence does not resemble human war, but rather the competition of individuals for jobs, markets, and materials. The essence of the struggle is the competition for the necessities of life that are insufficient to satisfy all.

Among nations there is competition in developing resources trades, skills, and a satisfactory way of life. The successful nations grow and prosper; the unsuccessful decline. While it is true that this competition may induce efforts to expand territory at the expense of others, and thus lead to conflict, it cannot be said that war-like conflict among nations is inevitable, although competition is.

第26题:In the first paragraph, the author gives the definitions of some term in order to ________.

A) argue for the similarities between and human societies

B) smooth out the conflicts in human societies

C) distinguish between two kinds of opposition

D) summarize the that characteristic features of opposition and cooperation

In cities across the United States, old factories, warehouses, schools railroad statio
ns and other buildings are being renovated for new uses.City planners and private investors are finding the good buildings, no matter how old, can be remodeled for new purposes.“If you’d asked someone four or five years ago whether he’d rent an apartment in an abandoned piano factory of clothing warehouse, he’d have thought you were crazy,” says a New York architect.“Today, many people are eager to do it.” The renovating may include a former city hall or courthouse changed into offices; a bank or church changed into a restaurant; or , as in Plains, Georgia, a railroad station used as a center for a presidential campaign.

Only a few decades ago, renovation was unpopular and generally far more expensive than taking down abandoned building and string from the beginning.A change began in the 1960s with a number of well-advertised projects.They included Ghirardelli Square in San Francisco, where an old chocolate factory was restored and made into shops and restaurants, Trolly Square in Salt Lake, where unused warehouses were made into artists’ studios and apartments.

What caused the change? “One reason is nostalgia,” a San Francisco builder suggests.“Maybe old is better than new, many people are saying.Feelings about preserving attractive or historic buildings have changed a great deal.” A second cause is economy.The cost of tearing down an old building and constructing a new one from nothing now has risen to the point where it is often less expensive to fix a solid older structure.Also builders realize that fixing up an existing building often requires no new permits, sewer lines, or water connections.

Even when the costs of restoration are the same as or a bit more than the costs of putting up a new building, fixing the old building may be better.A Boston architect says The advantage comes when you can develop a final project that is more desirable than a new building – one with the right location, more space, more floor area, a special character, materials of a particular quality.” Gradually, architects and builders are developing knowledge about renovation and preservation, bringing imagination and creativity to the job.

16.In the United States, renovating old buildings_____.

A.has had a long history

B.is becoming increasingly popular

C.is still unpopular

D.has just caught the fancy of architects and builders

17.Ghirardelli Square, Trolley Square, and the Soho district are projects that_________.

A.have been given much publicity

B.are little known to the public

C.have been widely discussed among builders and city planners

D.have changed the building business

18.“Nostalgia” in the 3rd paragraph most probably means________.

A.being conservative

B.being keen on saving money

C.being fond of things new

D.being fond of things of the remote past

19.Which of the following statements is true?

A.Every old building can be renovated for new uses

B.Renovating old buildings is always less costly than putting up new ones

C.Renovation does not require imagination and creativity

D.Fixing an old building may have advantages even when it costs a little more
