   The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

   The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat.An FDA official called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually, the agency says, their offspring(后代)are safe to eat as well.But research on cloned sheep is limited.So the FDA proposes that sheep clones not be used for human food.

   The United States this year could become the first country to agree to the sale of foods from cloned animals.First, however, the public will have ninety days to comment on three suggested documents.On December 28th the FDA released a long report, called a draft risk assessment, along with two policy documents.

   The agency says it must receive comments by April second.The FDA seemed ready to act several years ago, but a committee called for more research.

   For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

   Clones are still rare.They cost a lot and are difficult to produce.

   The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring.It says clones are expected to be used mostly as breeding animals to spread good qualities.

   Public opinion studies show most Americans do not like the idea of food from cloned animals.But this research also shows the public knows little about cloning.

   Cloning differs from genetic engineering.A cell taken from a so-called donor animal is grown into an embryo(胚胎) in the laboratory.Next, the embryo is placed into the uterus(子宮) of a female animal.If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

60.What’s the main purpose of the passage?

       A.To tell a interesting story.    B.To give some advice on foods.

       C.To give a report.   D.To compare different opinions.

61.Who believe that foods from cloning are safe to eat?__________

       A.Most Americans          B.An advisory committee    

       C.Critics                    D.The FDA

62.It can be inferred from the last paragraph that_____.

       A.cloning has much in common with genetic

       B.not every cell taken from a donor animal can grow into a genetic copy

       C.the donor animal should be a female one

       D.cloned animals grow faster than normal ones

63.Which of the following is true about foods from cloning?_______________

       A.They come from the sexually reproduced offspring of cloned animals.

       B.The food from first-generation cloned animals is very expensive.

       C.Only FDA has the right to sell the food.

       D.They will be sold mixed with those from naturally bred animals.

I have a rule for travel: Never carry a map. I prefer to ask for directions

Foreign visitors are often puzzled in Japan because most streets there don’t have names. In Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.” In the countryside of the American Midwest, usually there are not many landmarks. There are no mountains, so the land is very flat. In many places there are no towns or buildings within miles. Instead of landmarks,   people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile.”

People in Los Angeles, California, have no idea of distance on the map: they measure distance by means of time, not miles. “ How far away is the post office?”

You ask. “Oh,” they answer, “ It’s about five minutes from here.” You say, “Yes, but how many miles away is it?” They don’t know.

People in Greece sometimes do not even try to give directions because visitors seldom understand the Greek language. Instead of gibing you the direction, a Greek will often say, “ follow me.” Then he’ll lead you through the streets of the city to the post office.

Sometimes a person doesn’t know the answer to your question. What happens in this situation? A New Yorker might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers, “I don’t know.” People in Yucatan think that “ I don’t know” is impolite. They usually give an answer, often a wrong one. A visitor can get very, very lost in Yucatan!

One thing will help you everywhere ---- in Japan, in the United States, in Greece, in Mexico, or in any other place. You might not understand a person’s words, but maybe you can understand his body language. He or she will usually turn and then point in the correct direction. Go in that direction, and you may find the post office!

The passage mainly tells us that ______________.

       A there are not many landmarks in the American Midwest

       B never carry a map for travel

       C there are different ways to give directions in different parts of the world

       D New Yorkers often say, “I have no idea,” but people in Yucatan, Mexico, Never say this

The passage says, “ In Japan, people use landmarks in their directions.” The word “landmark” means _______.

A street names                      

B building names

C hotels, markets and bus stops 

D buildings or places are easily recognized

In which place do people tell distance by means of time?

A Japan                             B American Midwest

C Los Angeles, California.              D Greece

Which of the following is wrong?

  A Travelers can learn about people’s customs by asking questions about directions.

B People in some places give directions in miles, but people in other places give directions by means of time.

C A person’s body language can help you understand directions.

D People in different places always give directions in the same way: They use street names.

Among rich countries, people in the United States work the longest hours. They work much longer than in Europe. This difference is quite surprising because productivity per hour worked is the same in the United States as it is in France, Spain and Germany, and it is growing at a similar speed.

In most countries and at most times in history, as people have become richer they have chosen to work less. In other words they have decided to “spend” a part of their extra income on a fuller personal life. Over the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in the United States. We do not fully know why this is. One reason may be greatly lower taxes in America, which increase the rewards (回報) to work. Another may be more satisfying work, or less satisfying personal lives.

Longer hours do of course increase the GDP (國內生產總值). So the United States has produced more per worker than, say, France. The United Sates also has more of its people at work, while in France many more mothers and older workers have decided to stay at home. The overall result is that American GDP per head is 40% higher than in France, even though productivity per hour worked is the same.

It is not clear which of the two situations is better. As we have seen, work has to be compared with other values like family life, which often get lost in its interest. It is too early to explain the

different trends (趨勢) in happiness over time in different countries. But it is a disappointing idea that in the United States happiness has made no progress since 1975, while it has risen in Europe. Could this have anything to do with trends in the work-life balance (平衡)?

 

56.From the text we know that the author ___________.

       A.believes that longer working hours is better

       B.prefers shorter working hours to longer ones

       C.says nothing certain about which pattern is better

       D.thinks neither of the patterns is good

57.Which of the following countries has more of its people at work?

       A.Spain.                                             B.France.

       C.Germany.                                        D.America.

58.In the last paragraph, the underlined word “which” refers to __________.

       A.family life                                        B.situations

       C.other values                                     D.trends

59.What message can we get from the text?

       A.The GDP of Europe is higher than that of America.

       B.Two possible reasons are given for working longer hours in the US.

       C.People all over the world choose to work less when they are richer.

       D.Americans are happier than Europeans.

60.Which of the following would be the best title for the text?

       A.Americans and Europeans.                B.Staying at Home.

       C.Work and Productivity.                     D.Work and Happiness.

Joe Templer should have known better. After all, he works for a large auto insurance company. It won't hurt to leave the key in the truck this once, he thought, as he filled his gas tank at a self service gas station. But moments later, as he was paying the money, he saw the truck being driven away.

In 1987, 1.6 million motor vehicles were stolen in the United States one every 20 seconds. If _________________, experts predict annual vehicle thefts could exceed two million by the end of the decade.

Vehicle theft is a common phenomenon, which has a direct impact on over four million victims a year. The cost is astonishing.      

Many police officials blame professional thieves for the high volume of the thefts. It is a major money maker for organized crime. Typically, stolen cars are taken to pieces and the parts sold to individuals. But as many as 200,000 cars are smuggled out of the country every year. Most go to Latin America, the Middle East and Europe.

Only about 15 percent car thefts result in an arrest, because few police departments routinely conduct in depth auto investigations. When thieves are arrested, judges will often sentence them to probation(緩刑), not immediately put them in prison because the prisons are overcrowded with violent criminals.

One exception is a Michigan program that assigns 92 police officers to work full time on the state's 65,000 car theft cases a year. Since 1986, when the effort began, the state's auto theft rate has fallen from second in the nation to ninth.

77  Why do you think Joe Templer should be blamed according to the writer? (Please answer within 10 words.)
