Genes that control factors such as size, color and shape determine the differences in fruit. And now that scientists have discovered how to detect different genes, farmers can hand over a young and tender branch to have its genes checked prior to planting. It works the same way as a detective checking fingerprints. Once farmers know which trees are good and which are bad, they can discard the bad ones. Farmers can even create new varieties according to their individual tastes.In the past three years, tens of thousands of tests were carded out to determine the genetic (基因的) features 0f fruit. Zhang, a Chinese scientist, showed a photo of a DNA-test and pointed to the shining lines on it, saying thatthe lines were genetic signs that tell us what a tree's fruit will be like. For example, the ordinary pear tree bears fruit after four years. But now it only takes a month to test the DNA from a young leaf and a farmer will know everything about its fruit. By mixing different types of trees with suitable genes, farmers can create whatever fruit trees they want.

21.Detecting different genes in plants is like().

A.the examination of human finger-prints

Within a large concrete room, cut out of a mountain on a freezing-cold island just 1,000 k
ilometers from the North Pole, could lie the future of humanity.

The room is a vault (地下库) designed to hold around 2 million seeds, representing all known varieties of the world's crops. It is being built to safeguard the world's food supply against nuclear war, climate change, terrorism, rising sea levels, earthquakes and the collapse of electricity supplies. "If the worst came to the worst, this would allow the world to reconstruct agriculture on this planet," says Cary Fowler, director of the Global Crop Diversity Trust, an independent international organization promoting the project.

The Norwegian (挪威的) government is planning to create the seed bank next year at the request of crop scientists. The $3 million vault will be built deep inside a sandstone mountain on the Norwegian Arctic island of Spitsbergen. The vault will have metre-thick walls of reinforced concrete and will be protected behind two airlocks and high-security doors.

The vault's seed collection will represent the products of some 10, 000 years of plant breeding by the world's farmers. Though most are no longer widely planted, the varieties contain vital genetic properties still regularly used in plant breeding.

To survive, the seeds need freezing temperatures. Operators plan to replace the air inside the vault each winter, when temperatures in Spitsbergen are around -18℃. But even if some disaster meant that the vault was abandoned, the permanently frozen soil would keep the seeds alive. And even accelerated global warming would take many decades to penetrate the mountain vault.

"This will be the world's most secure gene bank," says Fowler. "But. its seeds will only be used when all other samples have gone for some reason."

The project comes at a time when there is growing concern about the safety of existing seed banks around the world. Many have been criticized for their poor security, ageing refrigeration (冷藏) systems and vulnerable electricity supplies.

The scheme won UN approval at a meeting of the Food and Agriculture Organization in Rome in October 2005. A feasibility study said the facility "would essentially be built to last forever".

The Norwegian vault is important in that ______.

A.the seeds in it represent the rarest varieties of world's crops

B.the seeds in it could revive agriculture if the worst thing should happen

C.it is built deep in a mountain on a freezing-cold Arctic island.

D.it is strong enough against all disasters caused by man and nature

Passage Four Dressing fashionably was very important in fourteenth-century Spain. This

Passage Four

Dressing fashionably was very important in fourteenth-century Spain. This was especially true for any man who considered himself an aristocrat or dandy. Before going out, a well-dressed man would put on his finest boots, one of his embroidered caps and his favorite beard, dyed to match the color of his clothing.

Believe it or not, false beards were once as popular as neckties are today. Beards had for years considered a sign of strength and manhood, and the bigger and thicker they were, the better. Those unfortunates who had little facial hair were forced by custom into wearing false beards made of horsehair. Soon, however man in the Spanish fashion world was wearing them too, while many quite substantial real beards were shaved off to make way for the false variety.

By day, the fashionable dandy might wear a yellow or a crimson beard to impress his friends, but in the evening a long black beard was proper for serenading his senorita, Any color or shape of beard could be had.

However, as you can imagine, the growth of this unusual custom created many interesting problems. People with similar beards were mistaken for one another. Creditors could not find debtors, and police often arrested the wrong people, while the real villain escaped wearing their hairy disguises. The price of horsehair skyrocketed. Finally, King Philip IV of Aragon put a stop to all the foolishness by outlawing the wearing of false beards.

46. What is the passage mostly concerned with?

A. The size of beards.

B. The color of beards.

C. Varieties of false beards.

D. The custom of wearing false beards.

阅读材料,回答题。

Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated(自动化的) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks.

On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form. without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system.

When a form. introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are w-trained as operators, programmers, and data preparation staff. After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the frim, resulting from the introduction of computers.

The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.

On the other hand, many workers regard the trend toward wider use of computers inevitable.They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1954, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long ran.

The unfriendly feeling towards computers is developed from 查看材料

A.the possible widespread unemployment caused by their introduction

B.their use as part of automated production systems

C.the least possible number of operators

D.the production system in steelworks

Genetically-modified (GM) foodstuffs are here to stay.That’s not to say that food prod
uced by conventional agriculture will disappear, but simply that food-buying patterns will polarize: there will be a niche market for conventional foodstuffs just as there is for organic food.It may even be that GM food will become the food of preference because consumers come to appreciate the health benefits of reduced pesticide use.

Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.

The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.

The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.

It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.

6. According to the passage, food supplies have been increased by all the following except_____________.

A.pesticides

B.artificial fertilizers

C.improved varieties

D.transportation

7.How many chemicals are still less familiar to the scientists?()

A.20,000.

B.1,000

C.19,000

D.21,000.

8.Why will people prefer GM food in the future?()

A.Because it uses less pesticides.

B.Because it is much cheaper.

C.Because the production is increased.

D.Because it is organic food.

9.Which of the following is NOT true?()

A.By 2050, the world population will grow to ten or eleven billion.

B.In the 21st century, GM food will take the place of conventional food.

C.More and more people will reduce the overall land available for farming.

D.More and more people will consume more food and occupy more space.

10.The author’s attitude towards GM food is _______.

A.negative

B.positive

C.critical

D.uncertain

as a food. Today, cheese is available in an almost numerable variety of

kinds, flavors and consistencies. Cheese is made by many different races of S2.______

people under wide varying conditions all over tide face of the earth. And the S3.______

peoples who eat it like the various flavors and consistencies produced. S4.______

For the better understanding of the art and sciences of cheese-making S5.______

one needs to know what kind of product it is and how the manufacturer pro-

cedures developed over the years. Even though the varieties differ quite

widely in composition, cheese can be characterized as a product made from S6.______

milk in that the protein is coagulated and concentrated. S7.______

For centuries, cheese-making has been a farm and home industry with

the individual producers using surplus milk to make small batches of

cheese. Goat cheese making in the US still follows this general practice. It S8.______

was, and still is to a considerate degree, an art; since the middle of

the 19th century, however, more and more cheese has been made in specially

equipped factories with greater application of science in the manufacturing

procedure. Milk from all species has been used for cheese making. Be- S9.______

cause more attention has been given with increasing the productivity of the

bovine species, a large proportion of commercial cheese is now made from S10.______

cow milk; the milk from the buffalo, zebu, sheep and goats is also used extensively.
