　　For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
　　Indoor air pollution can cause a person to feel tired, to suffer eye-pain, headache and other problems. Some pollutants（污染物） can cause breathing disorders, diseases of blood and even cancer, Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. It is that when builders began making houses and offices they did not waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also began using manmade building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building— green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.
　　小题1:Generally speaking, indoor air pollution may be more harmful than the air outside because ________.

A．the man - made building materials let out dangerous gases inside houses

B．there may be more harmful gases outside houses

C．the flow of air indoors is limited

D．indoor air pollution can make a person seriously ill

　　小题2:The most effective way to clean the air is to use different kinds of plants because________.

A．they may let out more oxygen which people need

B．they can absorb different kinds of the harmful indoor chemicals

C．they can take in all kinds of indoor pollutants

D．they can make your house prettier and more healthy

　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.

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. 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

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
