By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward- looking city dealers in fresh meat, fresh fish, and butter. After the Civil War(1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the

icebox, a precursor of the modern refrigerator, had been invented. Making an efficient ice box was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, forwhich the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

1. The phrase "forward-looking" in line 3 is closest in meaning to ........................ .

A. progressive B. popular C. thrifty D. well-established

2. The author mentions fish in line 5 because.............................

A. many fish dealers also sold ice

B. fish was shipped in refrigerated freight cars

C. fish dealers were among the early commercial users of ice

D. fish was not part of the ordinary person's diet before the invention of the icebox

3. The word "it" in line 5 refers to ..................................... .

A. fresh meat B. the Civil War C. ice D. a refrigerator

4. The word "rudimentary" in line 10 is closest in meaning to ........................ .

A. growing B. undeveloped C. necessary D. uninteresting

5. According to the information in the second paragraph, an ideal icebox would ................

A. completely prevent ice from melting B. stop air from circulating

C. allow ice to melt slowly D. use blankets to conserve ice

6. The author describes Thomas Moore as having been "on the right track" to indicate that............................

A. the road to the market passed close to Moore's farm

B. Moore was an honest merchant

C. Moore was a prosperous farmer

D. Moore's design was fairly successful

7. According to the passage, Moore's icebox allowed him to ......................... .

A. charge more for his butter B. travel to market at night

C. manufacture butter more quickly D. produce ice all year round

English has become a world language because of its establishment as a mother tongue outside England,in all the continents of the world. This exporting of English began in the seventeenth century,with the first settlements in the United States,assisted by massive immigration in the nineteenth and twentieth centuries,that has given the English language its present standing in the world.

My lawyer, Mr. Turner, is the only man I know who has seen a ghost. He is a quiet even-tempered man whose life is spent in dealing with facts. He is the last person in the world to give way to fantasy. He has a wife and two children of whom he is proud, takes a modest holiday abroad every year and spends his Sundays gardening. He is knowledgeable about art and architecture, though he doesn’t pretend to be an expert by any means. It is, therefore, all the more surprising that he should be so insistent about the ghost. It happened, so he says, like this: He was travelling from London to the north of England by train. It was a misty November evening and the train was half empty. In fact, for the first part of the journey Mr. Turner had the carriage to himself and sat dozing over a newspaper. However, at the first stop a passenger jumped in, slamming the door behind him. He seemed out of his breath as if he had been running. He was a striking looking young man with dark, bushy hair and bright intelligent eyes. He was dressed rather oddly in a long waistcoat with silver buttons, tight trousers and embroidered waistcoat. Mr. Turner didn’t pay much attention to this because people wear all sorts of extravagant clothes these days and he had long grown accustomed to them. Presently, the two men got into conversation, as people do on long journeys. Mr. Turner was interested to discover that the young man was very knowledgeable about art – in particular portraits. His name, he said, was Joseph Hart, and he was on his way to visit an exhibition. It seemed that he worked in a famous London Art Gallery – a picture restorer, perhaps, thought Mr. Turner, he seemed to know a great deal about varnishes and paints, and even more about the subjects of certain portraits. When Mr. Turner asked his opinion of the portrait of a famous judge by an artist he admired, his companion laughed and said: “He’s only a reproduction – a good one I agree but you can’t talk to a reproduction”. He spoke as though the person in the portrait were still living. After a while the carriage got hot and steamy and Mr. Turner dropped off. He woke up just as the train was drawing up at a junction with a grinding of brakes. His companion had disappeared. A few days later, having returned to London, Mr. Turner found himself near the Art Gallery. Moved by some impulse, he went in and inquired for Joseph Hart. The attendant directed him to a room devoted to early nineteenth century portraits of well-known men. There was no one in the room and Mr. Turner looked around him. Without knowing quite how he had got there, he found himself standing in front of a full-length portrait of a young dark man in tight trousers and an embroidered waistcoat. The eyes smiled at him with a hint of amusement. The name-plate at the foot of the picture read: Joseph Hart, Gentleman, 1800-1835.
66. What kind of person was Mr. Turner?
A. Imaginative B. Fantastic C. Sensible D. Insensitive
67. Although he was a lawyer, Mr. Turner_________.
A. pretended to know a lot about art. B. knew something about art C. pretended to take interest in art. D. intended to learn more about art.
68. When the passenger entered Mr. Turner’s department, ________.
A. he was panting B. he was running C. the train was just training D. the carriage was half-empty.
69. The passenger’s clothes didn’t seem strange to Mr. Turner because ________.
A. he was used to wearing strange clothes. B. he liked people who wore strange clothes
C. everyone he knew wore strange clothes. D. he had seen a lot of people in strange clothes

A. The judge wasn’t alive. B. The judge was still alive. C. The picture was a copy. D. He hadn’t seen it.

I. Read the passage and choose the best answer from A, B, C or D. LIFE OF A MAN Thomas is now in his sixties, and is one of the many homeless people who live on the streets he buys a newspaper most days. Today, with his fellow tramps, he reads about yesterday’ s student demonstration. Like many of the tramps that live under the bridge in New York, Thomas was not always so poor. A long time ago he was in the Navy, and like many who have been to sea for a long time, he has stayed slim and fit. Despite the strict organization on board ship, he loved the life, and had the opportunity to see many countries. He visited Poland and Russia; in South Africa he realized what he valued in each country was the people he met. He was always astonished and delighted by the ways in which the people he met differed from one country to another. Some day, he hopes, everyone will see the world as he does. After many happy years in Navy, he had to retire. The good things in life always come to an end. His mother and father had long since died and he’d lost touch with his other relatives. He came to New York and became an industrial designer. He was happy, although it wasn’t the same as the sea. He never wanted to get married and have children. And then there was the period of darkness. He smiles sadly. He shrugs his shoulders and looks at his hands. There are tears in the corners of his eyes. This is something that he cannot bring himself to talk about. “It all went wrong”, he whispers. He was silent for a minute; then recovered. He began to talk more loudly. “Look at me now it makes me angry. And what about the President? He’s been in power for years, and look what he’s done for us. Nothing! I’m still out on the streets and live the life of a tramp.” 39. It would appear that Thomas _________ A. has organized a protest recently. B. takes an interest in important events. C. has no contact with other homeless people. D. is not as poor as he used to be. 40. When Thomas was in the Navy, he _________ A. only visited three countries. B. enjoyed the strict life on board ship. C. was very well paid for the job he did. D. liked meeting people from different countries. 41. Thomas changed his job because he _________ A. was too old to stay in the Navy. B. wanted to start a family. C. wanted to be near his relatives in New York. D. did not enjoy the work any more. 42. Thomas lost his job and became a tramp because _________ A. he did not have any family. B. he was tired of doing normal job. C. of reasons he does not want to discuss D. of the death of his parents. 43. The text states that Thomas thinks the President _________ A. should not allow home people to stay on the streets. B.should increase pensions for oldpeople. C. has not had enough time to change things. D.should have done more to help people like him

One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. He was standing at the edge of one of tanks where several of these highly intelligent, friendly creatures were kept. Elvar had just swum up alongside him and had turned on his back. He wanted Sagan to scratch his stomach again, as the astronomer had done twice before. But this time Elvar was too deep in the water for Sagan to reach him. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water into the air and made a sound just like the words "More!"

The astonished astronomer went to the director of the institute and told him about the incident.

"Oh, yes. That´s one of the words he knows," the director said, showing no surprise at all.

Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a "language", in the real sense of the word? Scientist don´t agree on this.

1/ The dolphin leapt into the air because

A. Sagan was too near the water

B. it was part of the game they were playing.

C. he wanted Sagan to scratch him again

D. Sagan wanted to communicate with him

2/ "Dolphins" brains are particularly well developed to

A. help them to travle fast in water

B. arrange sounds in different structures

C. respond to different kinds of sound

D. communicate with humans through sound

Read the text on the tight about the invention of semaphore. Five sentences have been removed. Choose from sentences A-F the one which fits each gap (l-4).There is one extra sentence which you do not need. There is an example at the beginning (0).

A Using ropes, these could be moved to form 49 different shapes that could be recognized easily.

B The main problem was that it could not be used during the night or on foggy days.

C These messages could be sent very quickly.

D The new republic faced enemies on all sides in the form of the forces of Britain, Austria, Holland, Prussia and Spain.

E In August 1794, it carried its first message, the news of Napoleon's victory at Le Quenoy.

F A system was built between London and the south coast, and other countries followed.

War has been called 'the mother of invention', and this was certainly true in the French Revolutionary wars in 1792. 1 | D | What the Revolutionary Government urgently needed was a reliable system of communication.

Claude Chappe, who was a priest and an engineer, had developed a telegraph system, but had not been able to test it fully. However, his brother Ignace was a member of the government, and arranged for Claude's system to be tested. It turned out to be a great success and started a new form of high-speed communication.

The two brothers had a series of towers built 5 to 10 km apart. At the top of each tower was a tall wooden mast, and they attached one horizontal and two vertical wooden beams to this mast. Claude called this system 'semaphore', which comes from the Greek meaning 'bearing a sign'. 2 ( )

Operators in each tower watched neighbouring towers through a telescope and then passed the message on to the next one in the line. The first line stretched from Paris to Lille, a distance of 2.40 km. 3 ( ). At an average speed of three signals a minute, it was carried in 20 minutes, more than 90 times faster than messengers on horseback.

Once the value of Chappe's system was understood, it soon became the standard method of communication in Europe. 4 ( ). By the time the electric telegraph was developed, France had more than 550 semaphore towers stretching 4,800km.

Unfortunately, Chappe's system had some disadvantages. 5 ( ) The towers were also expensive to maintain and the cost of staff was high. In the end, Chappe was depressed by these criticisms of his inventions and by claims from other engineers that they had invented semaphore, and he committed suicide in 1805.

Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a "language", in the real sense of the word? Scientist don´t agree on this.

1/ The dolphin leapt into the air because

A. Sagan was too near the water

B. it was part of the game they were playing.

C. he wanted Sagan to scratch him again

D. Sagan wanted to communicate with him

2/ "Dolphins" brains are particularly well developed to

A. help them to travle fast in water

B. arrange sounds in different structures

C. respond to different kinds of sound

D. communicate with humans through sound

At sixteen Henry Vincent was separated from his family as a result of the war. He wandered aimlessly from one country to another 1 before finally settling down in Australia, 2 where he trained AS an electronics engineer. He established HIS own business but it called for so much work that marriage was out of the 3 question.
His retirement suddenly made him realise how lonely he was and he decided to 5 take up a hobby. Whit his interest in electronics, amateur radio seemed a natural choice. He installed his own equipment and obtained a license and his call sign, which is the set of letters and numbers used to identify oneself when making radio contact 6 with other radio amateurs all around the world.
Soon Henry had a lot of contacts in far-off places. One in particular was a man in California with 7 whom he had much in common. One night the man in California made to mention the village in Europe he had come from. Suddenly, Henry realised that this man was in fact his younger brother, Peter. At first, the two brothers were at a 8 loss for words but then little by little they filled 9 in the details of their past lives and not long afterwards Henry Vincent flew to California to 10 be reunited with his brother.
