But it has taken this charitable lemonade stand several years to come into use for the charity. Suzanne Miller, one kid’s mom, has taken part in charity races for the hospital for years. Her kids came up with the ____16____ of setting up a lemonade stand in the neighborhood. So they started to raise money for the charity. As Miller shared in public, “For the first year, we raised 220 dollars, and we thought that was amazing. Each year, it got ____17____ and bigger.” But it’s not just the profits (利润) that have gone up over the years, so have the volunteers. This year, Miller’s neighbor Leslie Rotarian’s three kids joined the charity program in ____18____ the lemonade stand. Miller posted online, “The lemonade stand for St. Jude that our neighbors hosted this weekend raised 3,515 dollars and offered it to my long-run goal. I CANNOT find words to ____19____ how I feel.” Leslie Rotarian added, “As a parent, it really makes you filled with joy.

D 【解析】 【导语】本文主要讲述了一群孩子通过设立柠檬水摊为圣裘德儿童研究医院募捐的故事,展现了小小的善举如何逐渐发展成大规模的慈善活动。 【13题详解】 句意: 但有时甚至是最小的行动也可能成为一件相当大的善举。 smallest最小的;prettiest最漂亮的;happiest最快乐的;worst最糟糕的。根据 “ It doesn’t have to be a great act, just something as simple as a lemonade stand.”(像柠檬水摊这样简单的事情)可知,强调行动的 “微小”。故选A。 【14题详解】 句意: 一开始,一群住在诺尔斯的孩子聚在一起参加一个筹款活动,为圣裘德儿童研究医院筹集资金。 nurses护士;doctors医生;parents父母;kids孩子。根据后文提到“kids got busy selling lemonade”(孩子们忙于卖柠檬水)可知,主语是孩子。故选D。 【15题详解】 句意: 他们总共为这项公益事业筹集了3500多美元。 pay支付;ask询问;collect收集,募捐;lend借出。根据“help raise money”(帮助筹款)可知,是募捐到超过3500美元。故选C。 【16题详解】 句意: 她的孩子们提出了在社区设立柠檬水摊的想法。 answer答案;research研究;idea想法;report报告。根据“came up with”(提出)可知,此处指提出了某种想法,通常搭配 “idea”。故选C。 【17题详解】 句意: 每年,募捐金额变得越来越高。 longer更长;higher更高;heavier更重;thicker更厚。根据“raised 220 dollars…got bigger”(从220美元增长)可知,金额 “变高”。故选B。 【18题详解】 句意: 莱今年,米勒的邻居莱斯利扶轮社员的三个孩子也加入了经营柠檬水摊位的慈善计划。 running经营(现在分词);building建造;cleaning清洁;moving移动。根据全文围绕“lemonade stand”的运营可知,此处需用”running”。故选A。 【19题详解】 句意: 我无法用语言描述我的感受。 check检查;describe描述;remind提醒;refuse拒绝。根据“CANNOT find words...  how I feel”可知,应是找不到词语描述自己的感受。故选B。 【20题详解】 句意: 但它确实帮助他们意识到他们在做什么,以及这些钱如何真正帮助拯救儿童。 consider考虑;change改变;finish完成;realize意识到。根据“...what they were doing and how that money could really help save children.”可知,这里是在强调柠檬摊筹款帮助了孩子们意识到这些。故选D。 三、阅读理解(每题2分,共26分) A 仔细阅读下列信息,把观光城市与游客的意愿进行匹配,并将A、B、C、D填在相应的位置上。其中一个选项为多余选项。 City Tours A Muscat is the capital city of Oman.

They were going to the theater with their friend Laurie. Amy also wanted to come with them. “I can’t take you, dear, because you aren’t invited,” began Meg, but Jo cut in impatiently, “You can’t go, Amy. Laurie invited only Meg and me.” Amy cried, “You’ll be sorry for this, Jo March.” While Jo and Meg were at the theater, Amy burned up Jo’s book of writings. Jo’s loving work of several years was gone in the fire. That night, Mother asked Jo to forgive (原谅) her sister, but Jo refused. The next day, Jo went to the river with Laurie to skate on the ice. Amy followed them. Jo saw her coming and turned her back. But Laurie did not see Amy. He warned Jo to stay away from the middle of the river. The ice there was thin. Jo heard him, but Amy did not know that. “Crack!” The sound turned Jo round. She happened to see Amy throw up her hands and go down with a scaring cry. The ice broke. Jo tried to call Laurie, but her voice was gone. She tried to rush forward, but her feet seemed to have no strength in them. Laurie’s voice cried out, “Bring a rail (横杆), Jo. Quick! Quick!” She never knew how she did it, but for the next few minutes she blindly followed what Laurie said. Together they got Amy out. It seemed that Amy was more scared than hurt. When Mother had put Amy to bed, Jo whispered, “Are you sure she is safe?” “Quite safe, dear. She is not hurt, and won’t even catch cold,” replied her mother cheerfully. “I was so scared when Amy fell into the water. I think my heart was beating even faster than hers at that time. If Laurie wasn’t there, everything would be too late. It was so stupid of me to be angry with my own sister! I am so sorry, Mom!” “Anger can make us do very bad things to people we love. We must learn to control our anger,” said Mrs March. Jo agreed. She looked at Amy in her bed and gave her a big kiss. (Adapted from Little Women) 24. What did Laurie invite Jo and Meg to do? A.

B 【解析】 【导语】本文改编自《小妇人》,讲述周六下午乔和梅格因劳里邀请去剧院,拒绝艾米同行,艾米生气烧掉乔的作品。当晚妈妈让乔原谅艾米,乔拒绝。次日乔和劳里滑冰时,艾米跟随,因冰薄落水,乔和劳里救起她。经此,乔认识到对妹妹发怒愚蠢,妈妈也教导要控制愤怒,乔最终原谅艾米。 【24题详解】 细节理解题。根据“One Saturday afternoon, Amy found her sisters Meg and Jo getting well-dressed. They were going to the theater with their friend Laurie.”可知,劳里邀请她们去剧院。故选C。 【25题详解】 细节理解题。根据“That night, Mother asked Jo to forgive (原谅) her sister, but Jo refused.”可知,结合艾米烧掉乔作品的事,可知乔因作品被烧,对艾米生气,所以周六晚上是生气的。故选A。 【26题详解】 细节理解题。根据“Laurie’s voice cried out, ‘Bring a rail (横杆).

One of the skills which many animals have is homing instinct (本能). These animals such as pigeons (鸽子), bees, salmons, frogs and cats are able to find their way home, sometimes making journeys of hundreds of kilometers back home. In our daily life, humans can make use of an animal’s homing instinct. Pigeons, for examples, have been used to carry messages or letters to the battles in times of war. Nowadays some people join in the Pigeon Association (协会) with the pigeons they have trained because they look on pigeon racing as a hobby and they even bet money on which pigeon would win in the race organized by the association. There are many interesting stories of the homing instinct at work. In the USA, a cat traveled 1,360 kilometers back to its old home after the owners moved, taking nearly a year over the journey. When we lose our kitten (小猫), we usually find her again near the house where she was born. We have a pond in the garden where the frogs come back every year. I even heard a dog which was injured by a car managed to take itself to the vet! There are other wonderful stories about the homing instinct. But how do these animals find their way home? They don’t have satellite navigation (导航) with them, they can’t read maps and, as far as we know, they can’t ask each other for directions. It seems that some animals, such as salmons, use their sense of smell to take them back to the place where they were born. Other animals such as birds and bees may use the sun, the stars and the moon to help them find their way. There is a theory (理论) that some animals have magnetic (磁的) cells in their brain which help them to find their way. As far as cats are concerned, nobody really knows how their homing instinct works and I am sure cats are never going to give away their secrets. 27. Which of the following is TRUE according to the passage? A. We have known how animals’ homing instinct works. B. Many people used to make money by flying pigeons. C. Most of the animals can go back home from far places. D. The writer tells some stories to show the animals’ ability. 28. What can we infer (推断) from the passage? A. We still need to make some secrets of nature clear. B. We must stop doing harm to the animals at once. C. We have already known everything well in nature. D. We should learn from nature and make inventions. 29. What’s the best title for the passage? A. Animals and Their Living Habits B. A Special Ability of Some Animals C. A Good Way to Protect Animals D. All Kinds of Animals in Nature 【答案】27. D 28. A 29. B 【解析】 【导语】本文主要介绍了动物的归巢本能,通过具体事例说明某些动物具有长途返家的特殊能力,并探讨了可能的导航机制,同时指出人类对这一现象仍存在未解之谜。 【27题详解】 细节理解题。 根据第2段“There are many interesting stories of the homing instinct at work…I even heard a dog which was injured by a car managed to take itself to the vet!”可知,作者通过多个故事展示动物的归巢能力。故选D。 【28题详解】 推理判断题。 根据第3段“As far as cats are concerned, nobody really knows how their homing instinct works”可推断,自然界仍有许多未解之谜(如猫的导航机制)。故选A。 【29题详解】 最佳标题题。 全文围绕动物归巢本能展开,列举鸽子、猫等案例并探讨原理,B项“A Special Ability of Some Animals”最能概括这一主题。故选B。 D The last Eurasian lynxes (猞猁) in the British Isles lived a life of danger as they moved quickly away from the campfire and vicious (凶险的) dogs, and hid in holes. Because of disappearing woodlands, being short of animals for food, and hunting, lynxes started to disappear from these Islands about 1,500 years ago. But experts hope to bring the Eurasian lynxes back to Scotland one day. Wildlife conservationists (保护者) in Switzerland, Germany, France, and other countries have taken Eurasian lynxes from elsewhere in their areas and introduced them again to protected forests, allowing their populations to grow. Now they are hoping to do the same thing in Scotland. Returning the lynxes would do more than just improve the numbers of this once-endangered animal. A win for the lynxes is a win for the forest and the planet. When the Eurasian lynxes disappeared, so did the Scottish landscape. Without these lynxes and other animals hunting them, deer population increased (增加) a lot. Those animals lived on the leaves of trees and bushes for food, and soon large areas of the Scottish forest disappeared since it couldn’t grow fast enough to keep up with the deer’s wish for food. Birds and rodents that depended on shelter (庇护所) in the lower level of forest plants became food for foxes, which lynxes also hunt. Experts trying to restore (恢复) the forests have to put up fences to keep deer from eating leaves of young trees. But with lynxes hanging out in the woods, experts think these lynxes would keep deer from harming the young trees, helping the forests make a comeback. And that would have even bigger influences. The Earth is losing woodlands as people cut down trees to make room for farming, and to sell the wood for products like furniture and toilet paper. Only in a year alone, the Earth lost as many trees as would cover an area larger than Michigan. So restoring forests in places like Scotland can help provide more space for wildlife and even fight climate change. That’s because trees take in carbon dioxide (二氧化碳), which takes in the sun’s heat and warms our planet. 30. We can know from the passage that the experts are trying to ________. A. buy more lynxes from abroad to keep their populations growing B. ask people to take part in the education program of saving lynxes C. put up more fences to stop deer from eating leaves on the trees D. know about lynxes’ habits to get them used to new environment 31. According to the passage, the experts tell us that ________. A. lynxes play a role in protecting the forests and the planet B. it’s helpful to cut down trees to make room for farming C. putting up more fences can help protect lynxes from dogs D. planting trees has nothing to do with the climate change 32. What’s Paragraph 3 mainly about? A. How we keep the population of wildlife successfully. B. What the disappearance of Eurasian lynxes has led to. C. Why we provide more space for wildlife in the forests. D. When we will bring Eurasian lynxes back to Scotland. 33. What’s the writer’s main purpose in writing this passage? A. To talk about the food chain of wildlife in the forests. B. To introduce the living habits of the lynxes in Scotland. C. To ask us to take part in the program of raising lynxes. D. To show us a way to protect the forests and the planet. 【答案】30. C 31. A 32. B 33. D 【解析】 【导语】本文是一篇说明文,主要讲述了专家希望通过重新引入欧亚猞猁来恢复苏格兰的森林生态平衡,并阐述了猞猁对森林和地球环境的积极影响。 【30题详解】 细节理解题。根据“Experts trying to restore (恢复) the forests have to put up fences to keep deer from eating leaves of young trees.”可知,试图恢复森林的专家不得不竖起栅栏,防止鹿吃幼树的叶子。故选C。 【31题详解】 细节理解题。根据“A win for the lynxes is a win for the forest and the planet.”及全文内容可知,猞猁对保护森林和地球环境有重要作用。故选A。 【32题详解】 主旨大意题。通读本段可知,第三段主要描述猞猁消失后鹿群泛滥导致森林破坏,以及依赖森林的鸟类和啮齿动物减少的连锁反应,B项符合。故选B。 【33题详解】 主旨大意题。通读全文可知,文章主要讲述了专家希望通过重新引入欧亚猞猁来恢复苏格兰的森林生态平衡,并阐述了猞猁对森林和地球环境的积极影响,所以文章主旨是向我们展示一种保护森林和地球的方法。故选D。 第二部分 本部分共5题,共20分。根据题目要求,完成相应任务。 四、阅读表达(第34~36题每题2分,第37题4分,共10分) 阅读短文,根据短文内容回答问题。 Tommy White has been rowing across the Pacific Ocean in a boat since he left California two months ago. He has been heading for Australia with only birds, fish and sharks alone. Crossing the Pacific Ocean is only part of it. Tommy has decided to go all the way around the world using his own energy. He would row bike, walk, and climb to explore the world without any help from motors (马达) at all. His plan included climbing the tallest peaks on six of the continents (大陆) around the world along the way. For the first part of his journey, he bicycled 5,546 miles from Seattle, Washington to Mount Mckingley in Alaska and back, walked 67 miles to base camp, and climbed up 20,320 feet to Mckingley’s top. Now in the second part of his dangerous journey, he is rowing to Australia. Why would he try to go around the world this way? He explains that he wants to encourage teenagers to dream their dreams and achieve their own goals. He wants to show them that there might be hard parts along the way, and sometimes they might not even get to that final goal. But they can experience great adventures and learn a lot along the way. Tommy has already faced and fought over lots of difficulties. For example, he wants to go south toward the Solomon Islands, but the strong wind and high waves in the sea have kept pushing him westward. If the weather doesn’t change, he will cheerfully change his plan, and aim to land at Papua New Guinea. One way or another, he’s sure he’ll get to his next goal: Australia. When his journey around the world takes him across land he enjoys meeting people along the way—especially children. He has already visited many schools and shared his story with the students and teachers there. Tommy encourages all teenagers to set their eyes on a goal and not to give up. He says, “With different goals, we will make great progress, and we will be farther along than when we started, even though we don’t get to some goals. That’s called real life!” 34. What has Tommy decided to use instead of motors? ____________________________________________ 35. How far did Tommy walk to the base camp? ____________________________________________ 36. Why does Tommy think about changing his plan? ____________________________________________ 37. If you want to make great progress, which is more important, setting small goals or making a big dream? Why? (Give at least two reasons.) ____________________________________________ 【答案】34. He has decided to use his own energy./ His own energy. 35. He walked 67 miles to the base camp./ 67 miles. 36. Because the strong wind and high waves have made his boat away from the route he expected./ Because his boat was a little away from the route he planned./ Because the strong wind and high waves in the sea have pushed him westward from his route./ Because of the strong wind and high waves in the sea. 37.

They were going to the theater with their friend Laurie. Amy also wanted to come with them. “I can’t take you dear, because you aren’t invited,” began Meg, but Jo cut in impatiently, “You can’t go, Amy. Laurie invited only Meg and me.” Amy cried, “You’ll be sorry for this, Jo March.” While Jo and Meg were at the theater, Amy burned up Jo’s book of writings. Jo’s loving work of several years was gone in the fire. That night, Mother asked Jo to forgive (原谅) her sister, but Jo refused. The next day, Jo went to the river with Laurie to skate on the ice. Amy followed them. Jo saw her coming and turned her back. But Laurie did not see Amy. He warned Jo to stay away from the middle of the river. The ice there was thin. Jo heard him, but Amy did not know that. “Crack!” The sound turned Jo round. She happened to see Amy throw up her hands and go down with a scaring cry. The ice broke. Jo tried to call Laurie, but her voice was gone. She tried to rush forward, but her feet seemed to have no strength in them. Laurie’s voice cried out, “Bring a rail (横杆), Jo. Quick! Quick!” She never knew how she did it, but for the next few minutes she blindly followed what Laurie said. Together they got Amy out. It seemed that Amy was more scared than hurt. When Mother had put Amy to bed, Jo whispered, “Are you sure she is safe?” “Quite safe, dear. She is not hurt, and won’t even catch cold,” replied her mother cheerfully. “I was so scared when Amy fell into the water. I think my heart was beating even faster than hers at that time. If Laurie wasn’t there, everything would be too late. It was so stupid of me to be angry with my own sister! I am so sorry, Mom!” “Anger can make us do very bad things to people we love. We must learn to control our anger,” said Mrs March. Jo agreed. She looked at Amy in her bed and gave her a big kiss. (Adapted from Little Women) 24. What did Laurie invite Jo and Meg to do? A. Read in the library. B. Skate on the ice. C. Go to the theater. D. Join a book show. 25. How did Jo feel on Saturday night? A. Angry. B. Relaxed. C. Tired. D. Hungry. 26 What can we know from the passage? A. Amy fell into the water near the bank of the river. B. Jo used a rail to pull Amy out with Laurie’s help. C. Laurie was too scared to do anything at that time. D. Amy said sorry to Jo after she burnt her writings. C We all know that animals are better at some things than our humans, and we can usually explain why. One of the skills which many animals have is homing instinct (本能). These animals such as pigeons (鸽子), bees, salmons, frogs and cats are able to find their way home, sometimes making journeys of hundreds of kilometers back home. In our daily life, humans can make use of an animal’s homing instinct. Pigeons, for examples, have been used to carry messages or letters to the battles in times of war. Nowadays some people join in the Pigeon Association (协会) with the pigeons they have trained because they look on pigeon racing as a hobby and they even bet money on which pigeon would win in the race organized by the association. There are many interesting stories of the homing instinct at work. In the USA, a cat traveled 1,360 kilometers back to its old home after the owners moved, taking nearly a year over the journey. When we lose our kitten (小猫), we usually find her again near the house where she was born. We have a pond in the garden where the frogs come back every year. I even heard a dog which was injured by a car managed to take itself to the vet! There are other wonderful stories about the homing instinct. But how do these animals find their way home? They don’t have satellite navigation (导航) with them, they can’t read maps and, as far as we know, they can’t ask each other for directions. It seems that some animals, such as salmons, use their sense of smell to take them back to the place where they were born. Other animals such as birds and bees may use the sun, the stars and the moon to help them find their way. There is a theory (理论) that some animals have magnetic (磁的) cells in their brain which help them to find their way. As far as cats are concerned, nobody really knows how their homing instinct works and I am sure cats are never going to give away their secrets. 27. Which of the following is TRUE according to the passage? A. We have known how animals’ homing instinct works. B. Many people used to make money by flying pigeons. C. Most of the animals can go back home from far places. D. The writer tells some stories to show the animals’ ability. 28. What can we infer (推断) from the passage? A. We still need to make some secrets of nature clear. B. We must stop doing harm to the animals at once. C. We have already known everything well in nature. D. We should learn from nature and make inventions. 29. What’s the best title for the passage? A. Animals and Their Living Habits B. A Special Ability of Some Animals C. A Good Way to Protect Animals D. All Kinds of Animals in Nature D The last Eurasian lynxes (猞猁) in the British Isles lived a life of danger as they moved quickly away from the campfire and vicious (凶险的) dogs, and hid in holes. Because of disappearing woodlands, being short of animals for food, and hunting, lynxes started to disappear from these Islands about 1,500 years ago. But experts hope to bring the Eurasian lynxes back to Scotland one day. Wildlife conservationists (保护者) in Switzerland, Germany, France, and other countries have taken Eurasian lynxes from elsewhere in their areas and introduced them again to protected forests, allowing their populations to grow. Now they are hoping to do the same thing in Scotland. Returning the lynxes would do more than just improve the numbers of this once-endangered animal. A win for the lynxes is a win for the forest and the planet. When the Eurasian lynxes disappeared, so did the Scottish landscape. Without these lynxes and other animals hunting them, deer population increased (增加) a lot. Those animals lived on the leaves of trees and bushes for food, and soon large areas of the Scottish forest disappeared since it couldn’t grow fast enough to keep up with the deer’s wish for food. Birds and rodents that depended on shelter (庇护所) in the lower level of forest plants became food for foxes, which lynxes also hunt. Experts trying to restore (恢复) the forests have to put up fences to keep deer from eating leaves of young trees. But with lynxes hanging out in the woods, experts think these lynxes would keep deer from harming the young trees, helping the forests make a comeback. And that would have even bigger influences. The Earth is losing woodlands as people cut down trees to make room for farming, and to sell the wood for products like furniture and toilet paper. Only in a year alone, the Earth lost as many trees as would cover an area larger than Michigan. So restoring forests in places like Scotland can help provide more space for wildlife and even fight climate change. That’s because trees take in carbon dioxide (二氧化碳), which takes in the sun’s heat and warms our planet. 30. We can know from the passage that the experts are trying to ________. A buy more lynxes from abroad to keep their populations growing B. ask people to take part in the education program of saving lynxes C. put up more fences to stop deer from eating leaves on the trees D. know about lynxes’ habits to get them used to new environment 31. According to the passage, the experts tell us that ________. A. lynxes play a role in protecting the forests and the planet B. it’s helpful to cut down trees to make room for farming C. putting up more fences can help protect lynxes from dogs D. planting trees has nothing to do with the climate change 32. What’s Paragraph 3 mainly about? A. How we keep the population of wildlife successfully. B. What the disappearance of Eurasian lynxes has led to. C. Why we provide more space for wildlife in the forests. D. When we will bring Eurasian lynxes back to Scotland. 33. What’s the writer’s main purpose in writing this passage? A. To talk about the food chain of wildlife in the forests. B. To introduce the living habits of the lynxes in Scotland. C. To ask us to take part in the program of raising lynxes. D. To show us a way to protect the forests and the planet. 第二部分 本部分共5题,共20分。根据题目要求,完成相应任务。 四、阅读表达(第34~36题每题2分,第37题4分,共10分) 阅读短文,根据短文内容回答问题。 Tommy White has been rowing across the Pacific Ocean in a boat since he left California two months ago. He has been heading for Australia with only birds, fish and sharks alone. Crossing the Pacific Ocean is only part of it. Tommy has decided to go all the way around the world using his own energy. He would row, bike, walk, and climb to explore the world without any help from motors (马达) at all. His plan included climbing the tallest peaks on six of the continents (大陆) around the world along the way. For the first part of his journey, he bicycled 5,546 miles from Seattle, Washington to Mount Mckingley in Alaska and back, walked 67 miles to base camp, and climbed up 20,320 feet to Mckingley’s top. Now in the second part of his dangerous journey, he is rowing to Australia. Why would he try to go around the world this way? He explains that he wants to encourage teenagers to dream their dreams and achieve their own goals. He wants to show them that there might be hard parts along the way and sometimes they might not even get to that final goal. But they can experience great adventures and learn a lot along the way. Tommy has already faced and fought over lots of difficulties. For example, he wants to go south toward the Solomon Islands, but the strong wind and high waves in the sea have kept pushing him westward. If the weather doesn’t change, he will cheerfully change his plan, and aim to land at Papua New Guinea. One way or another, he’s sure he’ll get to his next goal: Australia. When his journey around the world takes him across land, he enjoys meeting people along the way—especially children. He has already visited many schools and shared his story with the students and teachers there. Tommy encourages all teenagers to set their eyes on a goal and not to give up. He says, “With different goals, we will make great progress, and we will be farther along than when we started, even though we don’t get to some goals. That’s called real life!” 34. What has Tommy decided to use instead of motors? ____________________________________________ 35. How far did Tommy walk to the base camp? ____________________________________________ 36. Why does Tommy think about changing his plan? ____________________________________________ 37. If you want to make great progress, which is more important, setting small goals or making a big dream? Why? (Give at least two reasons.) ____________________________________________ 五、文段表达(10分) 从下面两个题目中任选一题,根据所给中文和英文提示,完成一篇不少于50词的英语文段写作。文中已给出内容不计入总词数。所给提示词语仅供选用。请不要写出你的真实校名和姓名。 题目① 38. 假如你是李华,你的英国笔友Mark对你日常生活中的个人收藏很感兴趣。请你给他回复电子邮件,向他介绍你收集的情况,并谈谈你对这些物品的打算。 提示词语:keep, so far, regard, share 提示问题: ①How have you collected these things? ②What are you going to do with them?
