On the night of May, 7,1942, a plane took off from an Air Force base in England to stop German fighters over the English Channel. The pilot of the plane was Captain Thomas Nash. Looking eastward, Nash saw twelve orange lights in a row, moving at an extremely high speed. As an experienced flyer, he had never seen anything like them. Thinking that they might be a new German weapon, he decided to follow them. But when he swung the plane around and headed directly for the lights, they disappeared.
Captain Nash may have been the first to see such orange lights but he wasn’t the last. His experience was repeated several times by pilots during World War Ⅱ in Europe and the Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animals – animals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are invisible from the earth. They feed in part on the air and partly on energy from sunlight. Being almost pure energy themselves, they can give light at night. During the day they become invisible.
Before World WarⅡ, continues the theory, there was little radiated (辐射) energy available on the earth’s surface. Then came the development of rockets, atomic reactor (核反应堆), and hydroelectric (水力发电的) plants. The space creatures are attracted by these sources of energy. At night when no energy is sent from sunlight, they go down into the lower levels to search a meal. They may even come into the scope of human eyesight. This explains the fact that they have been sighted now and then from the earth since 1942.
54．Which of the following best states the main idea of the passage?
A．The secret of nature can be completely explained.
B．Captain Nash may have been the first to see the lights in space.
C．Captain Nash saw twelve orange lights moving at a high speed.
D．According to an interesting theory, the orange lights are space animals.
55．The strange orange lights were first seen         .
A．from the ground                                  B．from a rocket ship
C．during World War I                             D．during World WarⅡ
56．The theory says that during the daytime the space animals        .
A．can’t be seen                                       B．shine brightly in the sky
C．can be seen from the earth                    D．visit the earth’s surface
57．If the space theory is true, the creatures go down to the lower places in order to         .
A．make connection with man                   B．search for man – made energy
C．attract curiosity                                   D．escape detection

阅读下列应用文及相关信息，并按照要求匹配信息。首先，请阅读以下世界古代奇观的简介：

　　A. The Great Wall was begun more than two thousand years ago. It was built to keep out invaders. It extends about six thousand seven hundred kilometers across northern China. Today, the Chinese government is working to repairparts of the wall and protect as much of it as possible. The Great Wall of China is one of the largest building projects ever attempted. It is also the only object built by people that can be seen from space.

B. The Coliseum in Rome, Italy was built almost two thousand years ago. The ancient Roman sports center could hold fifty thousand people who gathered there to watch public events. Experts say it is one of the finest examples of Roman design and engineering.

C. The city of Machu Picchu in Peru includes some of the best stone works ever built. The ancient Inca people built Machu Picchu high in the Andes Mountains, northwest of the city of Cuzco. Machu Picchu is about thirteen square kilometers. Historians say it might have been one of the last places of safety for the Incas who were fleeing invaders from Spain.

D. India is famous for its temples and buildings. The most famous is the Taj Mahal, considered one of the most beautiful buildings ever built. The fifth Mughal emperor, Shah Jahan, ordered it built in Agra in sixteen thirty-one. He built it as a burial place in memory of his wife. The Taj Mahal has tiny colorful stones inlaid in white marble. The structure seems to change color during different times of the day and night.

E. Abu Simbel was built more than three thousand years ago. It is about 280 kilometers south of Aswan on the western bank of the Nile River. It took an army of workmen and artists more than thirty years to cut the huge temple into the face of a rock mountain. In front of the main temple are four huge statues of Ramses the Second. Each statue is about twenty meters high.

F. Stonehenge also belongs on a list of ancient wonders. It is a circle of huge stones in southeastern England. Experts believe work began on Stonehenge about five thousand years ago. We know very little about Stonehenge. We do not even know how these huge stones were moved to the area. Much has been written about Stonehenge, but experts say they still are not sure what it was used for.

Fish Ears Tell Fish Tales

　 Fish have ears. Really. They’re quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths (耳石).

　 As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate (碳酸钙). By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish’s age, just like the growth rings of a tree.

　 Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They’re examining the chemical elements (元素) of each otolith ring.

　 The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring.

　 Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history.

　 In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles.

　 This is important to managers in the fish industry, who know nearly nothing about the whereabouts of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears.

1.What can we learn about fish ears from the text?

　A. They are small soft rings.

　B. They are not seen from the outside.

　C. They are openings only on food fish.

　D. They are not used to receive sound.

2.Why does the writer compare the fish to trees?

　A. Trees gain a growth ring each day.

　B. Trees also have otoliths.

　C. Their growth rings are very small.

　D. They both have growth rings.

3.Why is it important to study the chemistry of otolith rings?

　A. The elements of the otoliths can tell the history of the sea.

　B. Chemical contents of otoliths can tell how fast fish can swim.

　C. We can know more about fish and their living environment.

　D. Scientists can know exactly how old a fish is.

4.How would you understand “fish scientists are now lending their ears”?

　A. They are very interested in Thorrold’s research findings.

　B. They want to know where they can find fish.

　C. They lend their fish for chemical studies.

　D. They wonder if Thorrold can find growth rings from their ears.
