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
