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 pleasant New-year morning, Edward rose, and washed and dressed himself in haste. He wanted to be first to wish a happy New Year. He looked in every room, and shouted the words of welcome. He ran into the street, to repeat them to those he might meet. When he came back, his father gave him two bright, new silver dollars. His face lit up as he took them. He had wished for a long time to buy some pretty books that he had seen at the bookstore. He left the house with a light heart, intending to buy the books. As he ran down the street, he saw a poor German family, the father, mother, and three children shiveringwith cold. "I wish you a happy New Year," said Edward, as he was happily passing on. The man shook his head. "You do not belong to this country," said Edward. The man again shook his head, for he could not understand or speak our language. But he pointed to his mouth, and to the children, as if to say, "These little ones have had nothing to eat for a long time." Edward quickly understood that these poor people were in distress. He took out his dollars, and gave one to the man, and the other to his wife. How their eyes sparkled with gratitude! They said something in their language, which doubtless meant, "We thank you a thousand times, and will remember you forever." When Edward came home, his father asked what books he had bought. He hung his head a moment, but quickly looked up.

13. "I have bought no books," said he, "I gave my money to some poor people, who seemed to be very hungry and wretched. "I think I can wait for my books till next New Year. Oh, if you had seen how glad they were to receive the money!" "My dear boy;" said his father, "here is a whole bundle of books. I give them to you, more as a reward for your goodness of heart than as a New-year gift. "I saw you give the money to the poor German family. It was no small sum for a little boy to give cheerfully. "Be thus ever ready to help the poor, and wretched, and distressed; and every year of your life will be to you a happy New Year."

1.What is the main lesson of this passage?

A/We should always wish everyone we can happy New Year.

B/We should help foreign people.

C/We should not buy books, but instead we should buy food.

D/We should give all we can to those in need.

2.Why does Edward give his silver dollars to the German family?

A/Because his father has instructed him to always help foreign families in need.B/Because he pities them and knows they need the money more than he does.C/Because he didn't actually want the books after all and didn't want his father to find out.D/Because he saw his brother do the same thing last New Years.

3.What does the author mean when he says, "his face lit up"?

A/The light made his face bright. B/The light showed how happy he was. C/He turned on the light. D/He was overjoyed. 4.What causes Edward's father to give Edward a bundle of books? A/He wants to wish Edward a happy New Year. B/He wants to reward Edward's goodness. C/He wants Edward to learn how to read more fluently in German. D/He wants Edward to do better in school. 5.What do you think the German family will do with the money Edward gives them? A/They will give the money to those less fortunate than themselves.

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 ( )

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
