Actually, ecotourism can mean travel to far-off places of great natural beauty, but not always in a(n) ___52___ way. It’s a big business, and the attraction of money can cause people to think about ___53___ first. While ecotourism offers benefits to people and ecosystems, it leaves ecosystems open to negative effects,too.Costa Rica, once a Spanish colony, and independent since 1821, has an ecotourism industry worth over one billion dollars yearly, and thousands of jobs have been ___54___.

Choose the one that fits best according to the information given in the passage you have just read.(A)When I was young, it wasn’t the parental love that filled my thoughts in the spring. It was baseball.I loved everything about the game — the crack of a bat, the excitement of chasing a ground ball across short green grass, even watching the games on our old black-and-white TV. Yet looking back now, nothing was quite as important to me as the annual ritual (老规矩) of playing catch with my dad.Dad was never much of a baseball fan, but as green leaves began to shoot on bare branches and warmth returned to the air, he would grab his old mitt (棒球手套) and head out to the yard with me just the same. There was something beneficial about playing catch with him, the hum of the ball as it sailed through the air, and the friendly pop as it hit the leather netting. We may have been 50 feet apart, but the flight of that ball connected us, forming as strong a relationship as any father-son talk ever could have.I was never the star of my Little League team, yet Dad never cared about that. Every year, he would be out there, waiting to field any false throw I sent his way.As I grew older, I realized that our game was a reflection of our relationship — that even if a problem didn’t involve a glove and a ball, Dad would always be there to handle anything I threw in his direction. His devotion to our springtime ritual showed his devotion to me — not only to my love of baseballl but also to my life.I’ve often heard it said that “the devil is in the details.” Now I realize that in my relationship with my father, love was in the details.66. When the author was young, he didn’t care much about ______.A. the sound of hitting a ballB. the company of his fatherC. the joy of running after a ballD. the games broadcast on TV67. The author’s father practiced catching baseball with him on warm spring days, ______.A. having a father-son conversation with himB. killing time while doing some physical exerciseC. making him an excellent baseball playerD. giving him a guiding hand in his life68. We can learn from the passage that ______.A. a yearly celebration was held to start their spring baseball catching ritualB. the author and his father used to have a loose relationship with each otherC. the author fully realized his father’s love for him when he was youngD. the author’s father always stood by him whenever he was in trouble69. What is the passage mainly about?A. The same hobby shared between the author and his father.B. The way the author and his father used to spend spring days.C. The author’s sweet memory of his father’s love for him.D. The analysis made by the author about father-son relationship.70. Where does the passage most probably come from?A. An Apple Store leaflet.B. Apple Website.C. A textbook of app designing.D. A science magazine.71. Which of the following best summarizes the feature of Powerful apps for iPad mini?A. An amazingly clear display.B.

Order an iPad mini with Retina display online then collect it at your favorite retail store.73. Who would be the potential readers of the passage?A. Apple product fans.B. App software developers.C. Apple product sellers.D. Information technology engineers.(C)The term culture now is more used to describe everything from the fine arts to the outlook of a business group or a sports team. In its original sense, however, culture includes all identifying aspects of a racial group, nation, or empire: its physical environment, history, and traditions, its social rules and economic structure, and its religious beliefs and arts.The central beliefs and customs of a group are handed down from one generation to another. It is for this reason that most people regard culture as learned rather than innate. People acquire a culture because they are not born with one. The process by which a person develops a taste for regional foods, accented speech, or an outlook on the world over time, therefore, is known as enculturation (文化适应).Cultures are often identified by their symbols —images that are familiar and coated with meaning. Totem poles (图腾柱) carved with animals and creative figures suggest aspects of the Native American peoples of the Pacific Northwest but more literally represent specific tribes (部落). In Asia and India, the color of yellow is connected with temples while in ancient China it was a color only the emperor’s family was allowed to wear. Thus, different cultures may respond to a symbol quite differently. For example, to some a flag may represent pride, historical accomplishments, or ideals; to others, however, it can mean danger or oppression.To individuals unfamiliar with cultures outside their own, the beliefs, behaviors, and artistic expression of other groups can seem strange and even threatening. A society that ranks all other cultures against its own standards is considered to be ethnocentric(from the Greek ethnos, meaning “people,” and kentros, meaning “center”). A strongly ethnocentric society assumes also that what is different from its own culture is likely to be inferior and, possibly, wrong or evil.All people are ethnocentric to some degree, and some aspects of ethnocentrism, such as national pride, contribute to a well-functioning society. An appreciation for one’s own culture, however, does not prevent acceptance and respect for another culture. History documents the long-term vigour and success of multicultural groups in which people from numerous and various cultural backgrounds live and work together. Extreme ethnocentrism, in contrast, can lead to racism — the belief that it is race and racial origin that account for variations in human characteror ability and that one’s own race is superior to all others.74. What does the word “innate” in Paragraph 2 most probably mean?A. Instinctive.B. Developed.C. Believable.D. Cultivated.75. Which of the following is true according to the passage?A. Different interpretations of a symbol help to distinguish one culture from another.B. An ethnocentric country opens welcoming arms to cultures different from its own.C. Culture consists of some positive features of a racial group, nation or empire.D. People from various cultural backgrounds often reach an agreement on some image.76. What can be inferred from the passage?A. All aspects of ethnocentrism can produce negative effects on a society.B. Racism is unlikely to bring about serious conflicts among different cultures.C. Respect and acceptance of different cultures are a proper cultural attitude.D. Countries with a strong sense of national pride play a superior role in the world.77. Which might be the best title of the passage?A. Culture, the origin of racial superiorityB. Culture, a faithful mirror of historyC. Culture, the vigour of world developmentD. Culture, a distinctive identity of a nationSection CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Some of the most popular programmes on British television, all with their regular millions of loyal viewers, are ‘soaps’ such as Coronation Street, Eastenders and Emmerdale. (A ‘soap’ is an informal word for a ‘soap opera’, which is a television story, in daily or weekly episodes (连续剧集), about the daily lives of the characters in it.)In every soap there is comedy and tragedy, and storylines of all kinds. In every soap there is the inevitable gossip, and there is the essential character who brings misfortune on himself — or herself, the spiteful woman who hates the success of her sister in marrying a man with money and whose childish behavior splits the family.To some degree, of course, the regular episodes provide many people with an adult kind of comic, rather like Dickens’ serialized novels did. At times, the actions and characters in them seem quite realistic; at other times, they go to the other extreme and show actions that look as if they are straight from the pen of the best fiction writers. But perhaps the fall into clearly fictional comedy or tragedy is necessary to remind regular viewers that their daily amount of ‘soap’ is no more and no less than a shot of fiction, and that the characters are not real.Certainly life is never dull in a soap. If one of the adolescents buys a motorbike and a young child lives round the corner, you can bet the two will meet in an accident. If two people fall in love and get married, you can be sure that a friend will cast an insult on the character of one of them, enough to break up the marriage. After all, this is not life; this is a soap! Reality makes way forfiction. The viewers who think that they are watching even a reflection of reality only bring disappointment to themselves. But there are still viewers who follow the comings and goings of the characters on screen with unreasoning faith, believing that the events are real when characters are injured or ill, or even die, and send cards or flowers with best wishes, congratulations or sympathies.What many of us find difficult to understand is just why soaps have become so popular?(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)78. Coronation Street, Eastenders and Emmerdale are popular British soaps which ______.79. What are the two necessary elements of a soap opera?80. The regular viewers need to be reminded that the soap operas are ______.81. What do some TV viewers do when they are mad about the soaps?第II卷(共47分)I.
