Can you sell this for one chip of gold?”  Looking at the dirty ring,the young man became_41_, “One chip of gold? I’m not sure if it could be _42_at that price.”

The young man went to the market quickly. He _43_the ring to the vegetable ,meat and fish traders,and the others. But nobody was willing to _44_a chip of gold. He went back and reported, “Nobody was _45_enough to offer more than one chip of silver.” With a smile Zun-Nun said, “Now go to the gold shop in this street and show this to the _46_ trader. Don’t give your _47_,just see how much he will pay for it.”

The young man went to the shop _48_and returned with a(n)_49_expression on his face. He reported, “The trader offered one thousand  chips of gold for this ring,and the  50  of it was one thousand times higher than what the traders in the market offered.” Zun-Nun just smiled and _51_softly, “That was the answer to your question, my friend.

American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface.

Plastics are used today in everything from airplane wings to hundreds of object found in the home. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace.

The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure（构造）of plastic itself.

Plastic is made of monomers（单体）. These monomers link together to form polymers（聚合物）. Polymers give plastic its ability to be shaped and its strength. The research team found a way to make plastic that contains very small balloons filled with monomer liquid（液体）. When the new plastic cracks（裂开）, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy – five percent of the strength of undamaged plastic.

The new self – repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.

72．Which of the following can be the best title for the article?

A．Ever-Lasting Material Invented.

B．The Chemical Structure of Plastic.

73．We know from the passage that the repair is done as        .

A．the cracked plastic parts are changed

B．the plastic is made

C．the liquid is put into the plastic cracks

D．the plastic cracks

74．The scientist are planning to use the new material in space vehicles, bridges and people because         .

A．the plastic parts in them are required to last longer

B．the plastic parts in them are easily broken or damaged

C．the new material cannot be used elsewhere

D．they want to experiment in these places first

75．What can we know about the new material mentioned in the passage?

A．It is a kind of liquid that is commonly used.

B．It is more difficult to make than common plastics.

C．Its surface does not crack so easily as other ones.

D．It makes it difficult or impossible to replace plastic objects.

President Coolidge’s statement, “The business of America is business,” still points to a very important truth today — that business organizations have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions still possess this great prestige?

One reason is that Americans view business as being more firmly based on the idea of competition than other organizations in society. Since competition is seen as the main source of progress and development by most Americans, competitive business organizations are respected. Competition is not only good in itself; it is the means by which other basic American values, such as individual freedom, equality of opportunity, and hard work are protected.

Competition protects the individual freedom by making sure that there is no monopoly (垄断) of power. Compared with one and all-powerful government, many businesses compete against each other for benefit. If one business tries to take unfair advantage of its customers, it will lose to the competing business which treats its customers more fairly. Since there are many businesses competing for the customers’ dollars, they cannot afford to treat them unfairly and the customers would lose nothing.

A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it gives more support for freedom than government, even though government leaders are elected by the people while business leaders are not. Many Americans believe that competition is as important, or even more important, as democracy in protecting freedom.

Competition in business is also believed to strengthen the idea of equal opportunities. Competition is seen as an open and fair race where success goes to any person regardless of his or her social class background. Competitive success is commonly seen as the American choice of the higher social position which is not based on one’s family background. Business is therefore viewed as an expression of the idea of equal opportunities.

1.Which of the following is discussed as the main topic in the passage?

A. Competition in America’s business.        B. Freedom in America’s business.

C. Americans’ different values.                   D. Business against government.

2. Americans believe that they can realize their personal values ______.

A. when given equal opportunities

B. through doing business

C. by protecting their individual freedom

D. by means of competition

3.Who can benefit from business competition?

A. Businessmen who compete.

B. Customers of those businesses.

C. People with the idea of equality and freedom.

D. Both business organizations and government.

4.It could be inferred from the passage that the author believes ______.

A. business in other countries are not as competitive as those in the USA

B. business problems are very important to the American government

C. the competition in business plays a very important role in America

D. American business is the most powerful one in the whole world
