背景导读：
A
In 1974, in a village in Nepal, high in the Himalayan Mountains, something strange attacked a young girl called Lhakpa Dolma. When the police saw the footprints of the attacker, they were frightened. The footprints were huge!
“What kind of beast is this ” the people asked.
Lhakpa lived in the village, and every day she went up the mountain with her yaks(a kind of cow) so that they could eat the grass. Lhakpa knew exactly where to find the sweet, green grass for her yaks on this special mountain, which was called Mount Everest and is famous because it is the highest mountain in the world.
“Aren’t you frightened to walk in the mountains alone, Lhakpa ” asked her friends. “What about the yeti ”
But Lhakpa was not frightened. “The mountains of the Himalayas are huge!” she laughed. “I only go to one small place, not far from the village. And no one here has veer seen a yeti----it’s only a story.” So Lhakpa never really thought about the old yeti tales while she was working.
One day in 1974, Lhakpa took her yaks up the mountain as usual, but she could see that the yaks were not happy. “Perhaps they can smell a bear or a snow leopard near us,” she thought, and looked around.
Lhakpa couldn’t see anything, but she moved away. She took the yaks to another place, near a small stream. The water here came from the mountain snow and Lhakpa drank a little----it always tasted good! Then she sat down and watched her yaks eating.
Suddenly, Lhakpa heard a noise behind her---it was the noise of an animal, but it was very strange. She looked round very quickly---Lhakpa couldn’t believe her eyes! A huge creature was coming towards her on two legs. Lhakpa’ s eyes got bigger and bigger—it was a yeti!
The yeti took Lhakpa up in its long, hairy arms! She was terrified. She shouted and kicked, but it was no good ----- the yeti was too strong. “Help me!” she shouted. But the mountains were quiet, and nobody heard her.
But the huge beast was not really interested in Lhakpa --- perhaps she was too small. It put her down in the cold mountain stream, then it turned round and looked at the yaks, which were big and strong---- but the yeti was bigger. Lhakpa watched the yeti--- she was too terrified to move at first. With its strong arms, it quickly killed three of the yaks.
Then Lhakpa got out of the stream and ran home. She was frightened and cold. She told her parents about eh yeti killing the yaks. Her family were amazed at the story. They soon went to the police after they learned about it. But when the police and the people from the village arrived at the stream, they saw the huge footprints of a strange creature ---- but they didn’t see the yeti.

The very success of communication satellite system has raised wide spread concern about their future. Some countries are already using satellites for domestic(国内的) communications in place of conventional (传统的) telephone lines on land. Although this technique is extremely useful for linking widely scattered villagers in remote or mountainous regions, in heavily built-up areas where extensive telephone and telegraph systems already exist, domestic satellites (or “domsats”) are seen by the landline net work as an unfair competition. Despite such opposition, domsats are gaining support from many businesses and public interest groups in the United States, and seem likely to be more widely utilized in the future.
7. The passage mentions which of the following as a major advantage of domsats
A. They are inexpensive to operate
B. They easily connect distant points
C. They can be directed by remote control.
D. They can be built to be very light.

Many people will remember the flight of the space shuttle(航天飞机) Challenge, in June, 1983. The achievement of Sally Ride, America’s first woman astronaut(航天员) to fly into space, made this flight especially memorable. Students from two Camden, New Jersey, high schools, however, are probably to remember Norma rather than Sally whenever they think about the flight.
Norma didn’t travel alone. She brought about 100 companies along with her. Norma was an ant, a queen ant who, with her subject, made up the first ant colony(群体) to travel into space. The ants were part of a scene experiment designed by students to test the effects of weightlessness on insects(昆虫).
The equipment designed by the students for their colony functioned perfectly through the long space trip. The young scientists and their teachers were very sad to find that their insect astronauts had all died at some point before the container was returned to the school and opened. The problem did not occur in space, but on the ground after Challenger had landed. The container remained in the desert for nearly a week before the ant colony was removed. The hot, dry desert air dried out the colony’s container and the ants died from lack of moisture(水分).
The project was termed a success because it did provide useful information. Students will continue their efforts to pinpoint exactly what went wrong. They don’t want to be discouraged either by the demise of the ants or by the $ 10,000 shuttle fare the will have to pay to send the next colony of ants into space.
16. The story is mainly about________.
A. Sally Ride’s first ride B. space equipment for insects

A. death B. moisture C. space D. leader

C. no one fed them in space D. they dried out in the desert
20. On the next space trip, ants________.
A. will be sent without people B. should not be left in the desert
C. will have to pay double fare D. will die completely
