Man has always wanted to fly.Some of the greatest men in history have thought about the problem.One of these, for example, was the great Italian artist, Leonardo da Vince.In 1 sixteenth century he made designs for machines 2 could fly.But they were never built.
Throughout history, other less famous men 3 (want)to fly.An example was a man in England 800 years ago.He made a pair of wings from chicken feathers.Then he fixed them to his body and jumped into the air from a tall building.He did not fly very far.He fell to the ground and broke every bone in 4 body.
The first real step took place in France in 1783.Two brothers, the Mongol fliers, made a very large “hot air balloon”.They knew that hot air rises.Why not 5 a balloon with it? The balloon 6 (make)of cloth and paper.In September of that year, the King and Queen of France came to see the balloon.They watched it 7 the very first air passengers into the sky.The passengers were a sheep and a chicken.We do not know 8 they felt about the trip.But we do know that the trip lasted eight minutes and that the animals landed 9 .Two months later, two men did the same thing.They rose above Paris in balloon of the same kind.Their trip 10 twenty-five minutes and they traveled about 8 kilometers.

On any weekend throughout the year one can spend hours browsing through neighborhood flea markets(跳蚤市场). These are very popular for those who are in search of bargains and who have a keen eye for picking through what others have discarded. They hunt and search for something they can reuse. Americans love secondhand merchandise (商品) which can be bought cheaply and restored to its original use. In many cases the condition and the quality are still good, though the style might be outdated.
For some people searching through flea markets is a hobby which reaps rewards. They look for possible antiques among the items for sale or for old furniture which can. be restored with, a little care and used again. Many wise collectors often find rare items worth much more than their bargained price. Since prices are usually not fixed, if one is persistent a bargain can easily be struck. The owner may be selling a rare collectable and may not even be aware of its value. One of the great pleasures of shopping at such markets is the chance to bargain with the shop owner and settle for a price which one can afford and is willing to pay.
Perhaps even more enjoyable than flea markets are the weekend outdoor garage sales which have now become very much a part of American culture. These are held usually in the spring and fall when the weather is still good. Usually a homeowner, having decided that he would like to clear his residence of accumulated items which are no longer useful to him, advertises in a local paper that he is holding a garage sale. More than likely the goods on display are in good condition and great buys can be found if one has the time and patience to search carefully. The home owner places items for sale on display along the driveway leading to his garage or on his front lawn and waits for people to look at what he has to sell. Old magazines, books, paintings, bicycles, ice-skates, items of clothing and electrical appliances of every sort appear on a regular basis. If the owner is in a position where he must sell his home or plans to move soon, then he may be forced to practically give things away at a price far below their true worth.
What's the attitude many Americans have for flea markets?
A) They don't like them because it's a waste of time.
B) They suspect the goods sold there.
C) They don't trust the sellers of the goods.
D) They like them very much especially for good bargains.
What do Americans like to do with secondhand goods?
A) Resell them at a higher price.
B) Restore them and make them look new.
C) They use them as furniture in their homes.
D) They use them for a while and then discard them.
When people shop at a flea market, how can they settle on a price?
A) They can question their value.
B) They can compare with the other sellers.
C) They can bargain on a price acceptable to both.
D) They can expect a fifty percent discount.
Which of the following is TRUE about the garage sales?
A) Only in spring and fall can people enjoy them.
B) The goods orb display are all totally useless.
C) All the goods are selling far below their true worth.
D) One may buy a TV on a regular basis.

An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.
We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.
Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.
His team has completed a prototype (样机) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.
Einstein’s idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.
“If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you’re at sea level and that’s because the pressure is much lower up there,” said McCulloch.At one side is the evaporator (蒸发器), a bottle that contains liquid butane. “If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so,” says McCulloch. “That’s what makes it cold.”
The gas fridges based on Einstein’s design were replaced by Freon-compressor fridges partly because Einstein’s design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻两番) the efficiency.
However, McCulloch’s fridge is still in its early stages. “It’s very much a prototype,” he said. “Give us another month and we'll have it working.”
72.According to the passage, an early invention by Albert Einstein _______.
A.has been rediscovered because it costs much less and works more efficiently
B.is being redesigned because it could be used in places without electricity
C.has just been found to be energy-saving and environmentally friendly
D.will be fully made use of and become the fridge of the future
73.Which of the following is TRUE according to the text?
A.Freon was used in fridges long before the 1950s.
B.Freon is what makes current fridges big polluters.
C.McCulloch thinks he could improve Einstein's design by using other types of vapors.
D.The fridge Malcolm McCulloch and his team designed will be put into production soon.
74.We can learn from the text that the prototype completed _______.
A.changed the air pressure around it
B.was tested on the top of Mount Everest
C.increased the liquid boiling temperature
D.used only pressurized gases to keep things cold
75.McCulloch’s words in Paragraph 6 _____.
A.serve as an explanation for the principle behind Einstein’s fridge
B.give you the reason why Einstein’s fridge was not efficient
C.tell you how to take advantage of low air pressure
D.show you how Einstein’s fridge works

The native people of Australia are called Aborigines. Most of them live in the deserts of Australia, where they neither plant crops nor keep any animals. All the year round they move here and there through the deserts in search of food and water. They must depend on their own skills to track down (搜寻) wild animals for food in order to stay alive. It has been said that an Aborigine has the “eyes of an eagle (鹰)”.
The following story shows how surprising the Aborigines’ skill at tracking is.
Once a gold robbery in a small Australian town left the police quite puzzled (困惑的). They had to call on an old Aborigine tracker for help. The tracker found a set of footprints in the dusty street, and said he thought they were the tracks of the thief. Before the tracker could follow the prints very far, a rainstorm broke and washed the tracks away. Some time after that, the Aborigine was in another town, and his sharp eyes picked out the same footprints he had seen days before. The police could hardly believe his story, but they went with him as he followed the tracks through the dirty streets and past the outskirts (市郊) of the town. After about half an hour’s walk, the tracker stopped near a wooden house and simply pointed. Sure enough, the wanted man was hiding inside.
1. What kind of life do you think the Australian Aborigines live?
A. A lazy life. B. A hard life.
C. An easy life. D. A boring life.
2. The old Aborigine lost the first tracks he had found because ______.
A. there was a sudden rainstorm
B. the streets were covered with heavy dust
C. they were mixed with many other people’s footprint
D. he had been too tired to find them after a long walk
3. What can we know about the old Aborigine from the passage?
A. He was a friend of the police’s.
B . He knew the thief before.
C. His tracking skills helped the police find the thief.
D. He made his living by tracking for the police.
4. Which of the following is the best title for this passage?
