It can bum trees, houses, animals or people. Sometimes big fires can burn forests. Nobody knows for sure how people began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope (绳子) and brought fire down. Today people know how to make a fire with matches (火柴) . Children sometimes like to play with them. But matches can be very dangerous. One match can bum a piece of paper and then it might bum a house. A small fire can become a big fire very fast. Fire kills many people every year. So you must be careful with matches.

Since the early 1930s, Swiss banks had prided themselves on their system of banking secrecy and numbered accounts. Over the years, they had successfully withstood every challenge to this system by their own government who, in turn, had been frequently urged by foreign governments to reveal information about the financial affairs of certain account holders. The result of this policy of secrecy was that a kind of mystique had grown up around Swiss banking. There was a widely-held belief that Switzerland was irresistible to wealthy foreigners, mainly because of its numbered accounts and bankers’’ reluctance to ask awkward questions of depositors. Contributing to the mystique was the view, carefully propagated by the banks themselves, that if this secrecy was ever given up, foreigners would fall over themselves in the rush to withdraw money, and the Swiss banking system would virtually collapse overnight. To many, therefore, it came like a bolt out of the blue, when, in 1977, the Swiss banks announced they had signed a pact with the Swiss National Bank (the Central Bank). The aim of the agreement was to prevent the improper use of the country’’s bank secrecy laws, and its effect was to curb severely the system of secrecy. The rules which the banks had agreed to observe made the opening of numbered accounts subject to much closer scrutiny than before. The banks would be required, if necessary, to identify the origin of foreign funds going into numbered and other accounts. The idea was to stop such accounts being used for dubious purposes. Also, they agreed not to accept funds resulting from tax evasion or from crime. The pact represented essentially a tightening up of banking rules. Although the banks agreed to end relations with clients whose identities were unclear or who were performing improper acts, they were still not obliged to inform on a client to anyone, including the Swiss government. To some extent, therefore, the principle of secrecy had been maintained. In the last paragraph, the writer thinks that______.
Unlike most sports, which evolved over time from street games, basketball was designed by one man to suit a particular purpose. The man was Dr. James Naismith, and his purpose was to invent a vigorous game that could be played indoors in the winter. In 1892, Naismith was an instructor at a training school, which trained physical education instructors for the YMCAs. That year the school was trying (1)______up with a physical activity that the men could enjoy (2)______ the football and base ball seasons. None of the standard indoor activities (3)______their interest for long. Naismith was asked to solve the problem by the school. He first tried to (4)______some of the popular outdoor sports, but they were all too rough. The men were getting bruised from tackling each other and (5)______hit with equipment. So, Naismith decided to invent a game that would incorporate the most common elements of outdoor team sports without having the real physical contact. Most popular sports used a ball. So he chose a soccer ball because it was soft and large enough that it (6)______no equipment, such as a bat or a racket to hit it. Next he decided (7)______ an elevated goal, so that scoring would depend on skill and accuracy rather than on (8)______ only. His goals were two peach baskets, (9)______to ten-foot-high balconies at each end of the gym. The basic (10)______of the game was to throw the ball into the basket. Naismith wrote rules for the game, (11)______of which, though with some small changes , are still (12)______effect. Basketball was an immediate success. The students (13)______it to their friends, and the new sport quickly (14)______on. Today, basketball is one of the most popular games (15)______the world.
I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren’’t for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream Cities can be frightening places. The majority of the population live in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of flats. Children become aggressive and nervous—cooped up at home all day, with nowhere to play; their mothers feel isolated from the rest of the world. Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don’’t even say hello to each other. Country life, on the other hand, differs from this kind of isolated existence in that a sense of community generally binds the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. But country life has disadvantages too. While it is true that you may be among friends in a village, it is also true that you are cut off from the exciting and important events that take place in cities. There’’s little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-dweller who leaves for the country is often oppressed by a sense of unbearable stillness and quiet. What, then, is the answer The country has the advantage of peace and quiet, but suffers from the disadvantage of being cut off; the city breeds a feeling of isolation, and constant noise batters the senses. But one of its main advantages is that you are at the centre of things, and that life doesn’’t come to an end at half-past nine at night. Some people have found (or rather bought) a compromise between the two: they have expressed their preference for the "quiet life" by leaving the suburbs and moving to villages within commuting distance of large cities. They generally have about as much sensitivity as the plastic flowers they leave behind—they are polluted with strange ideas a-bout change and improvement which they force on to the unwilling original inhabitants of the villages. What then of my dreams of leaning on a cottage gate and murmuring "morning" to the locals as they pass by. I’’m keen on the idea, but you see there’’s my cat, Toby. I’’m not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm No, he would rather have the electric imitation-coal fire any evening. We get the impression from the first paragraph that the author_______.
