The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The de¬vice is said to be the world’s first portable(便携的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-op¬erated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to trans¬late spoken English into Italian, German, French and Span¬ish. The product comes with separate cartridges(盒式存储器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Eu¬rope soon after the US introduction, with cartridges that trans¬late Italian, German, French and Spanish into English.
The Voice uses a microchip(微型集成电路片) to trans¬late languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language.

In the last 500 years, nothing about people — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可树)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu¬rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo¬ple starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.
1. according to the passage, which of the following has changed the most in the last 500 years?
A. Food. B. Clothing. C. Ideology. D. Language.
2. The word "some" in the last sentence of the first paragraph refers to________.
A. some cocoa trees B. some chocolate drinks.
C. some shops D. some South American Indians
3. Thousands of Irish people starved during the " Potato Famine" because________
A. they were so dependent on potatoes that they refused to eat anything else
B. they were forced to leave their homeland and move to America
C. the weather conditions in Ireland were not suitable for growing potatoes
D. the potato harvest was bad
4. according to the passage, which of the following statements is NOT true?
A. One third of the world’s population drinks coffee.
B. Coffee is native to Colombia.
C. Coffee can keep one awake.
D. Coffee drinks were first made by Arabs.
Lucien Rudaux,a French artist,was the first to use his artistic ability and his knowledge of astronomy in art.His paintings show a mixture of skilled observations,brilliant imagination and careful attention.As a result,many of his works have come surprisingly close to actual conditions on distant planets.His painting of Mars included moonlike craters(火山口) that were first photographed by the astronauts in 1965.His 1930 painting of a dust storm looks remarkably like a photograph of a storm taken by the astronauts in 1976.
The artist-astronomers,including Rudaux,made people interested in outer space by painting what turned out to be exact portraits of the planets.
小题1:The passage tells us _________.
| A．the surprising exactness of space artists | B．the popular success of Lucien Rudaux |
| C．the imaginations of great artists | D．the likeness between the Moon and Mars |
| A．exploring the planets | B．studying paintings |

Many animal and plant species have become extinct（灭绝的）and many more are in critical danger. Finding ways to protect the earth"s wildlife and conserve（保护）the natural world they inhabit（居住）is now more important than ever.
Dodo
The Dodo is a classic example of how human caused damage to the earth"s biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island"s trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.
Rhinos
The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves（保护区）. Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers（偷猎者）.
The Giant Panda
The future of the World Wildlife Fund"s symbol is far from certain. As few as 1000 remain in the wild． The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, The panda"s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose（造成）one of the most serious threats to the animals continued existence.
Whales
The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world"s oceans have been declared whale sanctuaries（保护区）, 7 out of 13 whale species remain endangered． Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions（碰撞）with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
Tigers
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.
小题1:It implies that _______.
| A．The Dodo lacked the ability to protect itself from other animals |
| B．Sailors to the Island of Mauritius lived mainly on the Dodo |
| C．The Dodo used to be a strong animal that liked fighting. |
| D．The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius |
| A．The Dodo, Rhino and Giant Panda． |
| B．The Rhino, Whale and South China Tiger. |
| C．The Rhino, Panda, Whale and Tiger. |
| D．The Dodo and the Bali, Javan, and Caspian tigers. |
| A．The whale’s rich oil |
| B．The panda"s black and white patched coat |
| C．The Rhino horn and tigers’ bones and organs |
| D．The Dodo’s delicious meat |
| A．The number of South China tigers has reached crisis point. |
| B．Many animals are threatened with extinction as a result of human activity. |
| C．People hunt for the endangered animals for high profit. |
| D．The Whale is the representing mark for the World Wildlife Fund． |
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like a science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to the small, non-hibernating mammals (哺乳动物) like rats.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "It’s like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia．Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system. There is a challenge of designing a suitable protective shelter (栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.
小题1:According to the article, the hibernation research ______.
| A．is just an idea | B．is always a science fiction |
| C．has already finished successfully | D．has made some progress |
| A．less sleep | B．more food | C．less energy | D．more movement |
Exploration Mission to Jupiter’s moon Callisto.
| A．will be | B．has been planned for |
| C．is certain to be | D．may be |
| A．Hibernation Study For Space Travel | B．Welcome To Our Space Travel |
| C．To Hibernate, To Live Longer | D．Welcome To The Milky Way |
A NASA satellite called QuikSCAT has discovered highways of wind over the Earth"s oceans. Scientists believe these invisible roads may explain why many nonflowering plants, such as mosses (苔) and lichens (地衣), grow where they do.
The satellite is able to send microwaves (微波) from space to the surface of the ocean. The pattern of signals that come back shows which way the winds are blowing.
Using this data, the scientists studied a group of islands in the southern hemisphere (半球), near Antarctica．Winds tend to blow anticlockwise (逆时针) in this region, but there are lots of local differences.
When the researchers compared these local patterns to botanical (植物学) data, they found that the wind had an important effect on where species of mosses, lichens, and other nonflowering plants grow.
For example, Bouvet Island and Heard Island, share 30 per cent of their moss species, 29 per cent of liverworts (叶苔), and 32 per cent of lichens — even though they are 4,430 kilometers apart. In contrast, Gough Island and Bouvet Island, separated by just 1,860 kilometers of sea, share only 16 per cent of mosses and 17 per cent of liverworts. They have no lichens in common.
Ferns (蕨类植物) and flowering plants don"t travel as well in the wind, so they don"t show the same kinds of distribution (分布) patterns.
小题1:This story is about _____.
| A．the discovery of wind highways | B．how wind travels |
| C．how wind affects different plants | D．one function of the wind |
| A．signal | B．pattern | C．information | D．research |
| A．Bouvet Island, Heard Island and Gough Island are all in the southern hemisphere. |
| B．Winds in the researched area blow anti-clockwise. |
| C．The scientists shouldn"t base this research on how winds affect where ferns grow. |
| D．Without the discovery of QuikSCAT, the research wouldn"t have made sense. |
