C
A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
“Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
64.   What can we infer from the first paragraph?
A.    FDA has waited for a long time to get this final report.
B.    Products from cloned animals have been put into the market before.
C.    People are having the products from cloned animals safely.
D.    There have been once opposite opinions against cloned products.
65.   What does the underlined word “wary” mean?
A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud.
66.   It will be a few years before foods from clones come into the market, partly because _____.
A.    people have little knowledge of the cloned animals
B.    supporters can’t give powerful evidence to support that
C.    the few cloned animals will first be used to create superior animals
D.    they are a new generation for the customers and are too valuable for the customers
67.   What can we conclude from the passage?
A.    FDA officials encourage people to eat more food from clones.
B.    FDA officials think the food from clones will sell better than ordinary food.
C.    People only worry about the health problems when it comes to foods from the clones.
D.    All the foods will not have detailed labels on them.

Mars Was Not Always Bitterly Cold

Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today.  The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.

The Caltech scientists say carbonate(碳酸盐) minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite(陨石) that had its beginnings near the Martian surface.

Today, the average temperature on Mars is sixty-three degrees below zero Celsius.

The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information.

Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth.

The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home."

1. The underlined word “establish” in Paragraph 1 probably means “___________”.

A.to set up

B.to make people accept a belief

C.to discover or prove

D.to start having a relationship with others

2.How did the scientists reach the finding?

A.By studying Allan Hills meteorite.

B.By using spacecraft orbiting Mars.

C.By studying minerals gathered on Mars

D.By studying a meteorite on the Martian surface.

3.According to the fourth paragraph, what have spacecraft orbiting Mars done?

A.Measuring the temperature of Mars.

B.Taking photos of the surface of Mars.

C.Confirming that there is water flowing on Mars.

D.Finding where human beings will probably land on Mars.

4.How did Allan Hills meteorite get its name?

A.From its original place on Mars.

B.From where it was found on the earth.

C.From the name of the scientist who found it.

D.From the name of the aircraft that discovered it

5. Where can we most probably read this passage?

A.In a biography of scientists.

B.In a geography magazine.

C.In an environment report.

D.In a science report.

Everyone knows that the Frenchmen are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?

At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs in the UK found that 70% felt that their efforts were not appreciated by the British public. Britain is hostile to success, they said. It has a culture of jealousy. As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood.” Jealousy is sometimes known as the “green – eyed monster” and the UK is its home.

Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money. Some were given a little, others a great deal. Those given a little were given the chance to destroy the large amount of money given to others – but at the cost of losing their own. Two thirds of the people tested agreed to do this.

This seems to prove that the entrepreneurs were right to complain. But there is also conflicting evidence. The Organization for Economic Cooperation and Development recently reported that the UK is now the world’s fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.

“It is not really success that the British dislike,” says Carey Cooper, a professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems proud or unfair or which separates them from their roots.”

Perhaps it is the entrepreneurs who are the problem. They set out to do things in their way. They work long hours. By their own efforts they become millionaires. But instead of being happy they complain that nobody loves them. It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.

1.Most entrepreneurs surveyed believe that        .

A.the British people hate success

B.the British people are hardworking

C.love of success is Britain’s national character

D.they are considered as “green – eyed monsters”

2.What does the result of the Warwich University’s test show.

A.Two thirds of the people tested didn’t love money.

B.Most people would rather fail than see others succeed.

C.An imaginary amount of money does not attract people.

D.Most people are willing to enjoy success with others.

3.The writer of the passage seems to suggest that         .

A.jealousy is Britain’s national character

B.British entrepreneurs are not fairly treated

C.the scientists at Warwich University did a successful test

D.the entrepreneurs in the UK do not behave properly

4.The best title for this article can be            .

A.Be More Modest and We Will Love You More

B.Proud Entrepreneurs

C.The Frenchmen are Romantic While The British are Hostile

D.Only Pains but No Gains
