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.

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.

Professor Reason recently persuaded 35 people to keep a diary of all their absentminded actions for two weeks. When he came to analyse their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups.
One of the women, for instance, on leaving her house for work one morning threw her pet dog her earrings and tried to fix a dog biscuit on her ear. “The explanation for this is that the brain is like a computer,”explains the professor.“People programme themselves to do certain activities regularly. It was the woman's custom every morning to throw her dog two biscuits and then put on her ear rings. But somehow the action got reversed(颠倒) in the programme.” About one in twenty of the incidents the volunteers reported were these “programme assembly failures”.
Twenty percent of all errors were “test failures”— primarily due to not verifying the progress of what the body was doing. A man about to get his car out
of the garage passed through the back yard where his garden jacket and boots were kept, put them on—much to his surprise. A woman victim reported:“I got into the bath with my socks on.”
The commonest problem was information “storage failures”. People forgot the
names of people whose faces they knew,went into a room and forgot why they were
there, mislaid something, or smoked a cigarette without realizing it.
The research so far suggests that while the “central processor” of the brain is liberated from secondtosecond control of a wellpractised routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be “captured” by another frequently and recently used programme, resulting in embarrassing errors.
1.The purpose of Professor Reason's research is _______.
A.to show the difference between men and women in their reasoning
B.to classify and explain some errors in human actions
C.to find the causes which lead to computer failures
D.to compare computer functions with brain workings
2.Which of the following might be grouped under “programme assembly failures”?
A.A woman went into a shop and forgot what to buy.
B.A man returning home after work left his key in the lock.
C.A lady fell as she was concentrating on each step her feet were taking.
D.An old man, with his shoes on, was trying to put on his socks.
3.The word “verifying” in paragraph 3 can be replaced by _______ .
A.improvingB.changingC.checkingD.stopping
4.According to the passage, the information “storage failures” refer to _______ .
A.the destruction of information collecting system
B.the elimination of one's total memory
C.the temporary loss of part of one's memory
D.the separation of one's action from consciousness
As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.
Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the longhours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of l
iving and downshifting is one of them.
Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs(郊区), leaving their two children with a nanny(保姆). Most evenings Daniel wouldn't get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by.
Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm here,” says Daniel, “and we took almost a year to make the decision to downshift. It's taken some getting used to, but it's been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier.”
Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about ittoo much or you might not do it at all.”

About one million years ago,the Ice Age began.The Ice Age was a long period of time in which four great glaciers(冰川) pushed southward to cover almost all the upper half of North America,and then melted away.Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada.The winters were long,and the cool summers were too short to melt much of the ice and snow.The evergrowing sheet built up to a thickness of two miles at its center.
As all glaciers do,these great glaciers slid(滑动). They pushed down giant trees in their paths and scraped(刮削)the earth bare(光秃秃)of soil.Many animals moved farther south to escape.Others stayed and were destroyed.
When winters of little snow came,the summer suns into the edges to the ice sheets.As the glaciers melted,rocks,soil and other things that had mixed with the ice and snow were left.New hills,lakes and rivers were formed.
The last of the great glaciers began its melting about 11 000 years ago.Itsmelting formed the Great Lakes.These lakes are today little changed from their early sizes the glaciers.This is the Mississippi Missouri Ohio system.These rivers were miles wide at first.Through the years they settle into their present channels.

The Channel Islands are a group of Britishowned islands lying in the English Channel(海峡) , 10 to 30 miles off the French coast , and 70 to 90 miles from the English coast. There are ten islands with a total land area of 75 square miles and a total population of 123,000. The three largest islands, Jersey, Guernsey, and Alderney, have long been known for the fine breeds(品种) of cattle that are raised on them and named after them.
In earliest known history the islands were considered part of Normandy, whic
h was part of France, but the ruler of Normandy became king of England in 1066, and from then on the islands were looked upon as British land. English control was unbroken until World War Ⅱ,when the Germans held the islands for five years.

Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for—its stadium(运动场)and theatres, its shops and restaurants. The tourists do not, however, see Pompeii's people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2 000 years.
Once, Pompeii was a busy city of 22 000 people. It lay at the foot of Mount Vesuvius, a grasscovered volcano(火山). Mount Vesuvius had not erupted(喷发)for centuries, so the people of Pompeii felt safe. But they were not.
In August of AD 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly,carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains, houses and shops. There was a stadium with 20 000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue colour in the bottom, so we know that the people of Pompeii liked wine. They liked bread too, metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread—a type of bread that is still sold in Italy today.
Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eyemakeup.
Ginseppe has died, but his work continues. One fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.
1.Why do large numbers of people come to Pompeii each year?
A.To visit the volcano.
B.To shop and eat there.
C.To watch sports and plays.
D.To see how Pompeiians lived.
2.Why had so many Pompeiians remained by volcanic Mount Vesuvius?
A.The city nearby offered all kinds of fun.
B.The area produced the finest wine in Italy.
C.Few people expected the volcano to erupt again.
D.The mountain was beautiful and covered with grass.
3.Why did the city uncovered look almost the same as it had looked in AD 79?
A.Because Ginseppe and his men dug it slowly and carefully.
B.Because the city was buried alive and remained untouched.
C.Because scientists successfully rebuilt the city with everyday objects.
D.Because nobody had lived in the city ever since the volcano erupted.
4.What do we know about the Pompeiians who lived 2 000 years ago?
A.They lived more or less the same as Italians now do.
B.They liked women wearing all kinds of makeup.
C.They enjoyed a lazy life with drinking and eating.
