第I 卷〔选择题〕一、阅读理解ATrist an da Cunha, a 38-square-mile island, is the farthest inhabited island in the world, according to the Guinness Book of Records . It is 1,510 miles southwest of its nearest neighbor, St. Helena, and 1,950 miles west of Africa. Discovered by the Portuguese admiral 〔葡萄牙海军上将〕of the same name in 1506 and settled in 1810, the island belongs to Great Britain and has a population of a few hundred.Coming in a close second-and often wrongly mentioned as the most distant island-is Easter Island which lies 1,260 miles east of its nearest neighbor-Pitcairn Island, and 2,300 miles west of South America. The mountainous 64-square-nile island was settled around the 5th century, supposedly, by people who were lost at sea. They had no connection with the outside world for more than a thousand years, giving them plenty of time to buildmore than 1,000 huge stone figures, called moat , for which the island is most famous.On Easter Sunday, 1722, however, settlers from Holland moved in and gave the island its name. Today, 2,000 people live on the Chilean territory 〔智利领土〕. They share one street, a small airport and a few hours of television per day.1.It can be learned from the text that the island of Tristan da Cunha ________. A. was named after its discoverer B. got its name from Holland settlers C. was named by the British governmentD. got its name from the Guinness Book of Records2.Which of the following is most famous for moat ? A. Easter Island. B. Pitcairn Island. C. St. Helena. D. Tristan da Cunha.3.Which country does Easter Island belong to? A. Britain. B. Chile. C. Holland. D. Portugal.BChildren have their own rules in playing games. They seldom need a referee and rarely trouble to keep scores. They don’t care much about who wins or loses, and it doesn’t seem to wo rry then if the game is not finished. Yet, they like games that They also enjoy games that move in stages, in which each stage, thechoosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in it self.Grown-ups can hardly find children’s games exciting, and they often feel puzzled at why their kids play such simple games again and again. However, it is fond that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.4.What is true about children when they play games? A. They don’t need rules. B. They want to pick a better team. C. They can test their personal abilities. D. They can stop playing any time they like.5.To become a leader in a game the child has to ________. A. play well此卷只装订不密封班级 姓名 准考证号 考场号 座位号B. wait for his turnC. be confident in himselfD. be popular among his playmates6.The writer believes that ________.A. children play games without reasonsB. children’s games can do them a lot of goodC. children should invite grown-ups to play with themD. children should make better rules for their gamesCBeing considered a leader in our society is indeed of high praise. Leadership means power, commands, respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can't be easily swallowed down. They must be carefully cultivated.Different from popular belief, nost good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat then like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity〔慷慨〕that’s never forgotten.Giving credit is more effective than even the most constructive criticism〔批评〕, which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees, “Catch people doing something right!〞 he says. Then tell everyone about it.Take in formed risks. “The best leaders know that taking a risk is not a thought less exercise,〞 says management adviser Marilyn Machlowitz. “Sky divers don’t go up in an airplane without checking the parachutes beforehand.〞Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. but if you want to be a leader, you must learn to fail-and not die a thousand deaths. Pick yourself up and start all over again.Encourage enthusiasm. “When people understand the importance of work, they lend their mental strengths,〞 says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That’s a great force! Is this the best way to create excitement? Be enthusiastic yourself-You will be followed by everyone.7.The underlined word “cultivated〞 (paragraph 1) roughly means ________.A. comparedB. developedC. examinedD. encouraged8.The part “Always give credit〞 tells us that a leader should ________.A. praise everyoneB. give helpful criticismC. regard others as real heroesD. praise people for their good performances9.To be a good leader, you should _________.A. not be afraid of any risksB. think twice before taking risksC. try to avoid any possible failuresD. know what a thoughtless exercise is10.Which of the following can be the best title for the passage?A. How to Be a LeaderB. Not Many Can Be LeadersC. Leadership Is Very ImportantD. Leadership Is of Ski1ls and Techniques二、七选五How to Be a Pleasant PersonEach of us would love to be appreciated for the positive emotions that are exhibited around our surroundings. 11.The following steps will help you to be a pleasant person.Be modest. Understand that we all are humans. You might be rich or poor, black or white, short or tall etc. But above all we are all humans, which means we are all emotional beings. So treat others the way you would like to be treated.12.By offering a seat to an elderly person or throwing the football back to the young child, the inner self-satisfaction you get is priceless. Once you do so, you will feel good about yourself.Don’t reg ret. We all are reasonable beings and it is very human to do unreasonable things at times. However, it does not mean that we should regret what we did in the past. Every experience is a lesson which teaches you what to do and what not to do in future. 13.Forgive and forget. Always living in the past will only make one painful on the inside, which will reflect on the outside. 14.By doing so, your heart becomes light.Be grateful. Thank God and the Universe for yourself, your parents, your friends, your clothes, jobs, food, home etc. And every small thing makes a difference. 15.It will make you appreciate life.A. Be inspired.B. Be helpful.C. Little do we know that it is not a hard task at all.D. So be proud that you have learnt a lesson on your own.E. To have a pleasant emotion around you, it is better to let go.F. If possible, express your gratefulness for something every day.G. Throw flowers at others if you wish flowers to be thrown at you.三、完形填空In our modern world, when something wears out, we throw it away and buy a new one.

第I 卷(选择题)一、阅读理解ATrist an da Cunha, a 38-square-mile island, is the farthest inhabited island in the world, according to the Guinness Book of Records . It is 1,510 miles southwest of its nearest neighbor, St. Helena, and 1,950 miles west of Africa. Discovered by the Portuguese admiral (葡萄牙海军上将)of the same name in 1506 and settled in 1810, the island belongs to Great Britain and has a population of a few hundred.Coming in a close second-and often wrongly mentioned as the most distant island-is Easter Island which lies 1,260 miles east of its nearest neighbor-Pitcairn Island, and 2,300 miles west of South America. The mountainous 64-square-nile island was settled around the 5th century, supposedly, by people who were lost at sea. They had no connection with the outside world for more than a thousand years, giving them plenty of time to buildmore than 1,000 huge stone figures, called moat , for which the island is most famous.On Easter Sunday, 1722, however, settlers from Holland moved in and gave the island its name. Today, 2,000 people live on the Chilean territory (智利领土). They share one street, a small airport and a few hours of television per day.1.It can be learned from the text that the island of Tristan da Cunha ________. A. was named after its discoverer B. got its name from Holland settlers C. was named by the British governmentD. got its name from the Guinness Book of Records2.Which of the following is most famous for moat ? A. Easter Island. B. Pitcairn Island. C. St. Helena. D. Tristan da Cunha.3.Which country does Easter Island belong to? A. Britain. B. Chile. C. Holland. D. Portugal.BChildren have their own rules in playing games. They seldom need a referee and rarely trouble to keep scores. They don’t care much about who wins or loses, and it doesn’t seem to worry then if the game is not finished. Yet, they like games that They also enjoy games that move in stages, in which each stage, thechoosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in it self.Grown-ups can hardly find children’s games exciting, and they often feel puzzled at why their kids play such simple games again and again. However, it is fond that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.4.What is true about children when they play games? A. They don’t need rules. B. They want to pick a better team. C. They can test their personal abilities. D. They can stop playing any time they like.5.To become a leader in a game the child has to ________. A. play well此卷只装订不密封班级 姓名 准考证号 考场号 座位号B. wait for his turnC. be confident in himselfD. be popular among his playmates6.The writer believes that ________.A. children play games without reasonsB. children’s games can do them a lot of goodC. children should invite grown-ups to play with themD. children should make better rules for their gamesCBeing considered a leader in our society is indeed of high praise. Leadership means power, commands, respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can't be easily swallowed down. They must be carefully cultivated.Different from popular belief, nost good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat then like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity(慷慨)that’s never forgotten.Giving credit is more effective than even the most constructive criticism(批评), which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees, “Catch people doing something right!” he says. Then tell everyone about it.Take in formed risks. “The best leaders know that taking a risk is not a thought less exercise,” says management adviser Marilyn Machlowitz. “Sky divers don’t go up in an airplane without checking the parachutes beforehand.”Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. but if you want to be a leader, you must learn to fail-and not die a thousand deaths. Pick yourself up and start all over again.Encourage enthusiasm. “When people understand the importance of work, they lend their mental strengths,” says Lee Duc at. But when they get excited about the work, all their energy gets poured into the job. That’s a great force! Is this the best way to create excitement? Be enthusiastic yourself-You will be followed by everyone.7.The underlined word “cultivated” (paragra ph 1) roughly means ________.A. comparedB. developedC. examinedD. encouraged8.The part “Always give credit” tells us that a leader should ________.A. praise everyoneB. give helpful criticismC. regard others as real heroesD. praise people for their good performances9.To be a good leader, you should _________.A. not be afraid of any risksB. think twice before taking risksC. try to avoid any possible failuresD. know what a thoughtless exercise is10.Which of the following can be the best title for the passage?A. How to Be a LeaderB. Not Many Can Be LeadersC. Leadership Is Very ImportantD. Leadership Is of Ski1ls and Techniques二、七选五How to Be a Pleasant PersonEach of us would love to be appreciated for the positive emotions that are exhibited around our surroundings. 11.The following steps will help you to be a pleasant person.Be modest. Understand that we all are humans. You might be rich or poor, black or white, short or tall etc. But above all we are all humans, which means we are all emotional beings.
