At 2 p.m. on December 5, 1945, five Navy aircraft took off in perfect flying weather from a naval air installation in southeastern Florida, on a routine training mission over the Atlantic Ocean. Less than two hours later, the flight commander radioed that he was “completely lost”. Then there was silence. A rescue plane was sent to search for the missing aircraft, and it, too, disappeared. Despite one of history’s most extensive search efforts, involving more than 300 planes and dozens of ships, the Navy found nothing, not even an oil stain floating on the water.
This is just one of the many frightening stories told of “the Bermuda Triangle”, a mysterious area of the Atlantic Ocean roughly stretching southwest from Bermuda to the Florida coast and down to Puerto Rico. During the past 30 years, the triangle has claimed the lives of some 1,000 sailors and pilots.
Stranger yet are the numerous “ghost” ships that have been found floating crewless within the triangle. On one strange occasion in 1881, the cargo ship Ellen Austin discovered a small sailing ship, sails waving uselessly in the wind. The boat was full of wood with no one on deck. The captain of the Ellen Austin installed a new crew to sail it, but two days later, during a rough storm, the two ships temporarily lost sight of each other. When the captain again boarded the boat, he found his crew had disappeared. After a second crew was assigned, the ship was again lost in a fog bank. This time, no trace of the boat — or the crew — was ever found.
Charles Berlitz, a man with an interest in Atlantis, the legendary lost island, puts forward his theory that a giant solar crystal, which once was the power generator for Atlantis, lies on the ocean floor. From time to time, according to his theory, passing ships and planes set off the crystal, which confuses their instruments and engulfs them into the ocean.
Officially, the U.S. Navy does not recognize the triangle as a danger zone and is convinced that “the majority of disappearances in the triangle can be due to the unique features of the area’s environment.” These include the swift Gulf Stream current and the unexplored valleys under water of the Atlantic. Also, the triangle is one of only two places on earth where a compass needle points to true north rather than magnetic north, causing problems in navigation.
However, other scientists argue that beings from outer space have established a highly advanced civilization in the unexplored depths of the Atlantic inside the triangle. There, they believe, most of the missing vessels – and their crews – may still be on display for study by these higher intelligences.

Penguins live together,but each pair has a little piece of ground of their own.When a penguin wants to walk through its neighbor’s ground,it must ask permission.If it does not do that,it will have to fight.Most of the time,penguins live on the water.They eat shell fish and look after their children carefully.
All penguins are good parents—the male penguins are perhaps the best parents in the world. They walk in the sea in the middle of the dark Antarctic water.

The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem(生態(tài)系統(tǒng)). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas(熱帶草原). In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.
小題1:What is the passage mainly about?
A.Disappearance of African elephants.
B.Forests and savannas as habitats for African elephants.
C.The effect of African elephants’ search for food.
D.The eating habit of African elephants.
小題2:What does the underlined phrase “setting the terms” most probably mean?
A.Fixing the time.B.Worsening the state.
C.Improving the quality.D.Deciding the conditions.
小題3:According to the passage, which of the following statements is TRUE?
A.The African elephant is the largest animal on the earth.
B.African elephants have 300 pounds of plants every day, including small trees and underbushes.
C.The African elephant is in a way the builder of the environment like other land animals.
D.If the African elephant disappears, the whole ecosystem won’t be affected.
小題4:The passage is developed mainly by            .
A.showing the effect and then explaining the causes
B.pointing out similarities and differences
C.describing the changes in space order

In a few years,you might be able to speak Chinese,Korean,Japanese,F(xiàn)rench,and English-and all at the same time. This sounds incredible,but Alex Waibel,a computer science professor at US's Car-negie Mellon University (CMU) and Germany's University of Karlsruhe,announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.
One application,called Lecture Translation,can easily translate a speech from one language into an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme.
Another machine can send translations of a speech to different listeners depending on what languagethey speak. “It is like having a simultaneous translator right next to you but without disturbing the person next to you,”Waibel said
Prefer to read? So- called Translation Glasses transcribe(轉(zhuǎn)錄) the translations on a tiny liquid-crystal display(LCD) screen.
Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech.The electrodes could be replaced with wireless chips implanted in a person's face,according to research-ers.
During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he mouthed-without speaking aloud- a few words in Mandarin(普通話) to the audience. A few seconds later,the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”
This particular instrument,when fully developed,might allow anyone to speak in any number of lan-guages or,as Waibel put it,“to switch your mouth to a foreign language”. “The idea behind the universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are becoming more common in the world,”Waibel said.
With spontaneous(自發(fā)的) translators,foreign drivers in Germany  could listen to traffic warnings on the radio; tourists in China could read all the signs and talk with local people;leaders of different coun-tries could have secret talks without any interpreters there.
小題1:What can't be learned from the text?
A.The spontaneous translators will help us a lot.
B.There is no Muscle Translator in the world now.
C.Muscle Translators can translate what you think into speech if you just move your mouth.
D.A lecture translation can translate what you said into other languages easily.
小題2:What does the underlined word mean?
A.happening at at the same time.B.happening by itself.
C.similar in size.D.Similar in quality.
小題3:What's the final destination of inventing the language translators?
A.To make cultural exchanges between different countries easier.
B.To help students learn foreign languages more easily.
C.To make people live in foreign countries more comfortably.
D.To help people learn more foreign languages in the future.
小題4:What can be inferred from the seventh paragraph?
A.The translator is so good that it can translate any language into the very language you need.
B.The translator is becoming more and more common in the world as a bridge.
C.With the help of the translator,you only need to open your mouth when you want to say something without saying the exact words at all.
D.The translator needs to be improved before being put into market.
小題5:Where can we probably find this passage?
A.A newspaper.B.A magazine on science.
C.A fairy tale.D.A scientific fantasy book.

More than one in eight U. S. adults finds it hard to stay away from the Internet for several days at a time and about one in eleven tries to hide his or her online habit, according to a study showed on Tuesday.
The study by researchers from the Stanford University School of Medicine in California found one in eight adults admitted they needed to spend less time online, saying this showed "problematic Interact use" is present in a sizable portion (部分)of the population.
The study involved a nationwide telephone survey of 2,581 respondents in the spring and summer of 2004 with researchers then examining the data and preparing the report which appears in the October issue of CNS Spectrums.
The survey found that 68.9 percent of respondents were regular Internet users and 13.7 percent of the users found it hard to stay offline for several days at a time.
It found 12.4 percent often stayed online longer than intended, more than 12 percent said they saw a need to cut back on their Internet use, and 8.7 percent tried to conceal (隱瞞) "non-essential "Internet use from family, friends and employers.
A smaller number, 8.2 percent, said they use the Internet to escape problems or a bad mood, while 5.9 percent felt their relationships suffered because of too much Internet use.
One report published earlier this year said that 5 percent to 10 percent of the population likely will experience Internet addiction (上癮).
It said signs include a disregard for health or appearance, lack of sleep and reducing physical activities and social communications with others, as well as dry eyes and juries of hands and fingers.
小題1:From Paragraph 2, it tells us _______.
A.how to use the interact is a terrible problem to adults
B.how surfing the net has caused a bad result to people

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out.” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine –one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father's warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the center of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen:
“ENTER NAMES
VOYAGER 1: …
VOYAGER 2: …”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED(自動回收程序已啟動).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow (光芒), until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION(目的地): MARS. RETRIEVE DATE: 2025.”
小題1:Why did Mark touch the computer against his father’s warning?
A.He wanted to take a voyage.
B.He wanted to practice his skill

The National Gallery of Art in Washington, D.C., is one of the world’s greatest art museums. Millions of people have entered its doors to see paintings by the world’s fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery’s 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem.
In past times, the owners of paintings did not protect them from damaging changes in humidity(濕度)and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over.
Light is another enemy of paintings. Ultraviolet rays(紫外線)in light cause paintings to fade(褪色). Long ago, paintings often hung in dark churches and palaces. A coat of varnish(清漆)was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age.
To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new precautions, many of the world’s greatest paintings are being well protected for future generations to enjoy.
小題1:The text mainly tells us about_________________________.
A.the guard force in the National Gallery
B.protecting great paintings from nature
C.priceless paintings of past times
D.the air-conditioning and heating systems in the National Gallery
小題2:Which of the following is NOT an enemy of paintings?
A.Varnish.B.Temperature.C.Light.D.Humidity.
小題3:The underlined word “precautions” in Paragraph 4 is closest in meaning to ____________.  
A.decorationsB.problemsC.suggestionsD.a(chǎn)pplications
小題4:From the text we can infer that________________________.
A.great artists painted in dark churches and palaces
B.you can touch these paintings while you are in the National Gallery
C.the care of the world’s greatest paintings is both a big responsibility and a great challenge
D.the guard force in the Gallery has not done a good job

What picture do you have of the future? Will life in the future be better, worse of the same as now? What do you hope about the future?
Futurologists predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have disappeared by 2050. Instead, people will choose a programme from a menu and a computer will send the programme directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programmes, newspapers and books will come to us by computer.
In what concerns the environment, water will have become one of our most serious problems. In many places, agriculture is changing and they are growing fruit and vegetables to export. This uses a lot of water. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don’t act now.
In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the car and there won’t be any accidents. Today, many cars have computers that tell the drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. On the other hand, space planes will take people half way around the world in two hours. Nowadays, the United States Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angels to Tokyo in just two hours.
In the field of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots — they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.
In particular, medicine technology will have conquered many diseases. Today, there are electronic devices that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people see again and hear again and scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. Scientists will be able to do these things — but should they?
小題1:. What may happen in the field of entertainment in the future?
A.The programme made by yourself may be sent to TV.
B.A computer may choose TV programmes for you.
C.You may choose the channels from the menu in a computer.
D.What to broadcast on TV is decided by yourself.
小題2:. After reading Paragraph 3, we can know _______.
A.we should take measures to save water from now on
B.fruits will be more and more expensive
C.people will be short of supplies of vegetables
D.planting will need much less water in the future
小題3:. ________ is the main factor that makes driving much safe in the future
A.Good traffic conditionB.A good knowledge of driving skill
C.The role played by computerD.The use of new fuel in cars
小題4:. The following statements are wrong EXCEPT ________ according to the text.
A.The future world will be controlled by robots.
B.People won’t be blind or deaf in the future.
C.Fewer and fewer workers are needed in the future in factories.
D.Scientists have the right to clone people of different kinds.
