For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan（扫视）the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy（银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization（文明）much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
小题1:According to the passage, how many planets in our galaxy might be inhabitable?| A．5 billion． | B．10 billion. | | C．15 billion. | D．200 billion |
小题2:The first paragraph in this passage is mainly about ________ .| A．how scientists are looking for signs of life on other planets | | B．why scientists are looking for signs of life on other planets | | C．where scientists are looking for signs of life on other planets | | D．when scientists are looking for signs of life on other planets |
小题3:The underlined word “monitor” in the passage means“ ________ ”.| A．find | B．follow | | C．check | D．form |
小题4:Which of these statements is true based on the information in the passage?| A．The earth is one of the oldest planets in our galaxy. | | B．Most scientists believe that there is intelligent life on other planets. | | C．Scientists are trying different ways to find signs of life on other planets. | | D．Scientists don’t believe that there might be life on other planets. |

You are a German living in Berlin. One day you’ re walk¬ing down the street, minding your own business, when sudden¬ly a stranger comes up with a smile on his face. After stopping you, he holds a small electronic device (装置) close to his face and speaks slowly into it, saying, in English," Can you tell me where I can buy some sauerkraut?" What should you do? (a) Run away; (b) Call the police; or (c) Listen closely for the device to say in German," Konnen Sie mir bitte sagen, welches sauerkraut haufen kann?"
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.
1. The device held by the stranger is probably a kind of________.
A. a two-way radio B. language translator
C. easily-carried speaker D. a multi-functioned computer
2. What does the last sentence of the first paragraph mean?
A. Can you tell me where I can buy some sauerkraut?
B. Can I ask for some information from the police?
C. Would you like to try my device?
D. Would you not run away if I ask you where to buy some sauerkraut?
3. When the stranger says," Can you tell... sauerkraut?" he is ________.
A. learning German from his device
B. asking you the way to the sauerkraut shop
C. making fun of you with his device
D. testing his device for fun
4. Which of the following is not mentioned in the text?
A. The price of the hand-held microcomputer.
B. The function of the product Voice.
C. The producer pf the small electronic device.
D. The number of the device sold to the European coun¬tries. |
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.

For nearly a century before there was such a thing as a space program,a view of space was possible.People could see full views of the Moon,explore Mars(探测火星),and study the outer space beauty.All of this was made possible by a small group of artist-astronomers(天文艺术家) who worked to show people how other worlds in space might look.
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 |
小题2:According to the passage,artist-astronomers spent their lives _________.| A．exploring the planets | B．studying paintings | | C．painting the planets | D．producing spaceships |

Animal Conservation
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 |
小题2:Which group of the following animals has already ceased to exist according to the text?| 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. |
小题3:______ can serve as a cure for certain diseases.| 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 |
小题4:Which of the following statements is NOT true?| 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． |
