After reading the following passages, you will find several questions or unfinished statements, numbered 31 through 50. For eachquestion or statement there are 4 choices marked A, B, C and D. You should decideon the best choicePassage OneOne phase of the business cycle is the expansion phase. This phase is a two-fold one, including recovery and prosperity. During the recovery period there is ever-growing expansion of existing facilities, and new facilities for production are created. More businesses are created and older ones expanded. Improvements of various kinds are made. There is an ever increasing optimism about the future of economic growth. Much capital is invested in machinery and “heavy” industry. More labor is employed. More raw materials are required. As one part of the economy develops, other parts are affected. For example, a great expansion in automobiles results in an expansion of the steel, glass, and rubber industries. Roads are required; thus the cement and machinery industries are stimulated. Demand for labor and materials results in greater prosperity for workers and suppliers of raw materials, including farmers. This increase purchasing power and the volume of goods bought and sold. Thus prosperity is diffused among the various segments of the population. This prosperity period may continue to rise without an apparent end. However, a time comes when this phase reaches a peak and stops spiraling upwards. This is the end of the expansion phase.31. We may assume that in the next paragraph the writer will discuss__________.A. cyclical industriesB. union demandsC. the higher cost of livingD. the recession period32. The title below that best expresses the idea of this passage is __________.A. The Business CycleB. The Recovery stageC. An Expanding SocietyD. The Period of Good Time33. Prosperity in one industry __________.A. reflects itself in many other industriesB. will spiral upwardsC. will affect the steel industryD. will end abruptly34. which of the following industries will probably be a good indicator（指示物）of a period ofexpansion?A. Toys.B. Machine toolsC. Food stuffsD. Farming.35. During the period of prosperity, people regard the future_________.A. cautiouslyB. in a confident mannerC. indifferentlyD. opportunely Passage TwoAt one time, people used to travel to foreign countries because they thought they would be different from home---the buildings, the food, the national dress. Nowadays, however, one large city is very like another. They all have their Hilton or Sheraton Hotels which look like Hilton or Sheraton Hotels everywhere. They all have their McDonald’s, their KFCs, their Pizza Huts. Officebuildings look the same everywhere, and most city centers are full of office buildings. And, of course, people are driving the same brands of Japanese or European cars, usually wearing the same kinds of clothes and watching----except for a few programs----the same American movies and TV shows. Airports are the same everywhere and the world’s airlines are all flying the same aircraft, Boeings or Airbuses.What, therefore, is the purpose of foreign travel for people who are not on business? What do tourists hope to experience in a foreign country that they cannot experience at home? Why travel to foreign countries at all? The answer could be that people are very interested in the past. It is a nation’s history that as often as is its main attraction. Most of today’s tourist s travel overseas to find out what foreign countries and cultures used to be like, not what they are like today. The word “cultural tourism” is now part of the language of tourism, and it is the museums and works of art in many countries that are their main attraction.If they are lucky---and have had sensible, strong governments---many countries will usually have at least a few beautiful places for tourists to visit.Finally there is perhaps a nation’s greatest attraction: its people. A nation is not just its historical buildings, its works of art or beautiful places; it is also the people who live in it. This is why a country such as Thailand attracts millions of people every year. They come mainly because of the friendliness of the Thai people. It is why the Pacific islands are also so popular. There may not be much to see or do on Fiji, but there are lots of friendly, smiling people to make visitors feel welcome.36. The writer thinks that large cities in foreign countries__________.A. do not offer a warm welcome to foreignersB. share the same airlinesC. are very similar to each otherD. do not have god hotels37. The writer believe that many tourists who travel overseas are interested in a foreigncountry’s__________.A. airlinesB. hotelsC. programsD. history38. “Cultural tourism” means_____________.A. tourists being interested in a nation’s past and ideasB. studying the history of a feign countryC. visiting lots of museumsD. traveling overseas39. Some rather quiet places are popular because_______________.A. their people are so friendlyB. they sell their works of artC. they are expensiveD. they have sensible governments40. This passage mainly tells us _____________.A. the culture of ThailandB. how to plan an overseas tripC. dangerous experiencesD. why people travel to foreign countriesPassage ThreeLong, long ago, there was a poor man. He had an orange tree in his garden. One year the oranges on the tree were finer than any year else. One day he found one of his oranges much bigger than others. It was as big as a basket. Nobody had ever seen such a big orange. The poor man took the orange to the king. The king was very happy, and gave the man a lot of money for it. When a rich man heard of this, he said to himself, “why has the king give so much money for only one orange? I will take my gold cup to the king. He will certainly give me more money.” The next day when the king got the gold cup, he said to the rich man, “what a beautiful cup! I will show you something wonderful.

As we turned to go out of the door, Mum nodded politely to the nurse and said, "Thank you."Outside, Mum told me: "Dagmar is fine. No fever." "You saw her, Mum?" "Of course. I told her about the hospital rules, and she will not expect us until tomorrow. Dad will stop worrying as well. It's a fine hospital. But such floors! A mop is no good. You need a brush."46.
