Children walk away from Kestrel feeling at home in nature and at home in themselves. Each day begins with a morning circle where thanksgiving, songs and games bring us further into our bodies. The days are filled with nature-based games that expand our awareness, storytelling from skilled instructors and visiting elders, songs inspired by nature’s beauty, exploring the forest and looking for mysteries, sculpting clay, and wandering the caves. At the end of the day,with leaf and flower crowns on our heads, our faces painted and smiles on our faces, we’ll return! Kestrel is where your child will: Play and explore the beautiful outdoors. Experience and practice a variety of wilderness skills and native technology. Practice awareness, quiet mind, animal farms, curiosity, exploration, telling the story of the day and gratitude. Face personal and group challenges tailored to build awareness, self-confidence and group unity. Our Kestrel instructors are expert in guiding children to safety and helping them freely move in the direction of their own curiosity. 21. When can children join in Spring Discovery? A.

They will also tell you that you can make educated guesses on what a person might be thinking or feeling. Perhaps there really is nothing mysteriousabout the power to read minds. Perhaps it is simply human sense based on observation and educated guesses after all, but that’s really a useful ability to learn. Learn body language. How a person moves and holds their hands, and even what their eyes are doing are actually telling about what is going on inside their head. For example, pupils (瞳孔) tend to grow larger when you are interested in or excited about something. If you are talking to someone and making eye contact, finding their pupils are large and round, chances are that they are not feigning interest in the conversation. Someone biting their nails is probably nervous. Someone who folds their arms across their chest when they are not cold is probably trying to put a barrier between you and themselves. Learn to mentally put yourself in another’ s place. Scientists have recently discovered thatyour brain has neurons (神经元) that become active when you watch someone do something the same as we did the action ourselves. So when you are able to open yourself to understanding how other people are feeling, you can figure out reasons and predict future actions, reactions, even thoughts. Sometimes you can use Extra Sensory Perception (ESP) (超感觉力) to read someone’s m ind. This does not mean you will literally be able to read their mind like a book. Instead, you will receive impressions or feelings, which are difficult to explain. To improve your ESP abilities, take up meditation (冥想). Because meditation helps enable you to purposely put your brain in a state of relaxed awareness, where you will be more successful in reading people and receiving impressions. Practice and combine all of these steps. You will soon find yourself able to readpeople’s minds. 24. What is the passage mainly about? A. The ways of reading people’s minds. B. The steps of learning body language. C. The necessity of learning to read people’s minds. D. The relationship between mind and body language. 25. What does the underline word \A. Pretending. C. Finding. D. Declaring. 26. Why can you read someone’s mind when you mentally put yourself in his/her place? A. You suddenly have the ability to understand his or her feeling. B. Your imagination ability and your past experience are combined. C. Some neurons m your brain improve your observation ability. D. Your past similar experiences make some neurons in your brain active. 27. How does meditation help with mind reading? A. By making educated guesses on minds. B. By learning to make eye contact. C. By changing ESPabilities for the better. D. By strengthening impressions received. 24. 答案：A 主旨大意题根据原文最后一段Practice and combine all of these steps.

Kids are missing out on an essential life - relaxed down time,”says Dr. Charleotte Reznick.“Parents work, and kids do scheduled activities -- there’s little family time without pressure,”says Reznick.“One parent is taking the son to a soccer game, and the other parent is taking the daughter to her swim meet. Then there’s art class, baseball practice, extra tutoring, and more! By the time the family meet up for dinner, everyone is exhausted.”All the rushing makes for a short temper. “When parents are reduced to shouting at their children to get to them to listen, they lower their own self-esteem as well as losing the respect of their children,” says Dr. Carl Pickhardt. “While parents think it shows they’re serious about what they’re saying, they are really just showing helpless desperation at not getting their way.”These days what kids are learning at school and from the outside is a lot greater than it used to be even just a generation ago.“The problem is that stress-relieving activities -- reading, taking walks or hot baths, watching the sunset and other activities are not even part of most kids’ experience any more,”says Reznick.“There are so many more social-interaction opportunities in our computer age, but not all of them promote meaningful connections, which is another potential outlet for stress,”she says.One way to relieve stress is a simple technique called “the balloon breath”. It’s a great way for everyone to become calm so that they can respond thoughtfully rather than just react.Here’s how to do it. Imagine a deflated（未充气的）balloon in your stomach -- about two to three inches below your navel（肚脐）. Slowly breathe in to a count of 1...2...3... and feel the lower belly expand, and flatten as you slowly breathe out to a count of 1...2...3...28.What can we infer from the second paragraph?A.Kids can hardly enjoy family time due to heavy burdens.B.Saturday is the only leisurely day of the week for kids.C.The life of kids is becoming rich due to extra classes.D.Parents have no time on weekends to care for their kids.29.What does Dr. Carl Pickhardt think of parents when they yell?A.They have no self-confidence.B.They take what they say seriously.C.They are always behaving like children.D.They are less respected and seem desperate.30.What is the function of “the balloon breath”according to the seventh paragraph?A.To make one cool down.B. To test one’s patience.C. To raise one’s awareness.D. To fill a balloon with air.31.What is the purpose of the author writing this passage?A.To tell educators to be patient.B.To advise parents not to make life too stressful for kids.C.To encourage kids to pursue creativity.D.To show that kid need patience and love from their parents.DOpera is an art form that celebrates the human voice. No other art form creates excitement and moves the heart in the way that opera does, especially when performed by a great singer. Opera is an important part of the Western classical music tradition. It uses music, words and actions to bring a dramatic story to life. Opera started in Italy at the end of the 16th century and later became popular throughout Europe. Over the years, it has responded to various musicals. In recent decades, much wider audiences have been introduced to opera through modern recording technology. Some singers have become celebrities thanks to performing on radio, on TV, and in the cinema.However, in recent years, opera has been facing serious challenges. One current challenge to opera is economic. The shortage of money raises the broader question of how much should be paid to support opera singers and other artists. Society seems to accept the large salaries paid to businessmanagers and the multi-million-dollar contracts given to sports athletes. But what about opera singers? Somehow, people have the idea that artists can be creative only if they suffer in poverty, but this is unrealistic. If artists, including opera singers, lack the support they need, valuable talent is wasted.Not only the shortage of money, but also the way money is managed in the opera world has led to hardships. Principal singers are generally paid performance fees once they complete a show. They typically receive nothing during the many weeks of rehearsal（排练）before a show starts.Another problem faced by opera is how to meet the demands of audiences who are influenced by popular entertainment. Pop singers are often judged as much on the basis of how they look as how they sound. These demands may be unrealistic ans possibly harmful. Opera singers simply cannot make a sound big enough to fill a large theater or concert hall without a microphone if their body weight is too low. Emphasizing physical appearance over singing ability may cause audiences to miss out on the human voice at its best.There are no easy solution to opera’s problem and there are many different opinions about the value of opera. However, every year many young people register for music courses with hopes and dreams of developing their talent in this special art form. The fact that opera has survived many obstacles and continues to attract the rising generation shows that it remains a respected art form full of value.32.Which of the statements is TRUE according to the passage?A.Opera singers’ life stories are dramatic.B.Opera will soon appear on TV and in films.C.Opera fans thank celebrities for performing.D.Opera develops by adapting to new conditions.33.What can we know from Paragraph 2 and 3?A.Opera singers are financially insecure.B.Opera singers waste their valuable talent.C.Opera singers get paid before the show.D.Opera singers perform better if they are poor.34.What does the author try to say in Paragraph 4?A.Popular culture has had a positive influence on opera.B.Audiences know best how opera should be performed.C.Microphones should be used to make opera more enjoyable.D.Opera singers’ voices should be valued more than their looks.35.What would be the best title for this passage?A.The Economic Challenge to OperaB.Opera Faced with the DifficultiesC.Opera as Part of Popular CultureD.The Historical Context of Opera第二节（共5小题，每小题3分，满分15分）Developing good study habits isn’t easy. ___36___.

Kids are missing out on an essential life - relaxed down time, " says Dr. Charlotte Reznick."Parents work, and kids do scheduled activities - there' s little family time without pressure," says Reznick. "One parent is taking the son to a soccer game, and the other parent is taking the daughter to her swim meet. Then there's art class, baseball practice, extra tutoring, and more! By the time the family meet up for dinner, everyone is exhausted."All the rushing makes for a short temper. "When parents are reduced to shouting at their children to get them to listen, they lower their own self-esteem as well as losing the respect of their children," says Dr. Carl Pickhardt "While parents think it shows they' re serious about what they're saying, they are really just showing helpless desperation at not getting their way. "These days what kids are learning at school and from the outside is a lot greater than it used to be even just a generation ago."The problem is that stress-relieving activities - reading, taking walks or hot baths, watching the sunset and other activities are not even part of most kids' experience any more, " says Reznick."There are so many more social-interaction opportunities in our computer age, but not all of them promote meaningful connections, which is another potential outlet for stress, " she says.One way to relieve stress is a simple technique called "the balloon breath".

第Ⅰ卷阅读题一、现代文阅读(35分)（一）论述类文本阅读（9分，每小题3分）阅读下面的文字，完成1-3题o与西方文化相比，以人为本的人文精神是中国文化最根本的精神，也是一个最重要的特征。

在很多人的观念里，现在的人本主义是西方的舶来品，而根本不知道它原来是中国文化的土特产。

在中国文化中，西周以来就奠定了以人为本的文化精神和文化品格，而西方在公元以后奠定的是以神为本的文化，直至欧洲启蒙运动时期才高举起人本主义的旗帜，启发人不要做神的奴隶，要做人自己。

它的思想来源之一是古希腊罗马文化，而更重要的来源是16世纪以后传教士们从中国传回去的中国以人为本的人文文化。

中国文化以人为本的人文精神重点就在于人不是听外在的力量、命运主宰的，不是神的奴隶，而是要靠自身德行的提升。

以人为本的人文精神的核心就是决定人的命运的根本因素是人自己的德行，是以“德”为本，而不是靠外在的“天命”。

中国文化非常强调修身。

《大学》的第一句话是：“大学之道，在明明德，在亲民，在止于至善。

”第一个“明”是发扬光大，第二个“明”是形容这个德是光明正大的。

每个人都有明德，我们要把它发扬出来。

《大学》还有“八条目”：格物、致知、诚意、正心、修身、齐家、治国、平天下。

这中间修身是关键，所以说“自天子以至于庶人，壹是皆以修身为本”。

修身就是自我德行的完善和提升，不仅仅是在口头上、认识上，更重要的是要在行动上、实践上提升自己。

为了不断提升自我的德行，就必须防止物欲的引诱和腐蚀，人不能成为物的奴隶。

先秦末期的思想家荀子在书里记载了一句谚语：“君子役物，小人役于物。

The days are filled with nature-based games that expand our awareness, storytelling from skilled instructors and visiting elders, songs inspired by nature’s beauty, exploring the forest and looking for mysteries, sculpting clay, and wandering the caves. At the end of the day, with leaf and flower crowns on our heads, our faces painted and smiles on our faces, we’ll return!Kestrel is where your child will:Play and explore the beautiful outdoors.Experience and practice a variety of wilderness skills and native technology.Practice awareness, quiet mind, animal farms, curiosity, exploration, telling the story of the day and gratitude.Face personal and group challenges tailored to build awareness, self-confidence and group unity.Our Kestrel instructors are expert in guiding children to safety and helping them freely move in the direction of their own curiosity.21. When can children join in Spring Discovery?A. During the night.B. Only on the three Sunday-s,C. In the season of spring.D. From 10:00 am to 3:15 pm every day22. What can we know from the passage?A. Spring Discovery will be held every other year.B. The instructors are all experienced adult experts.C. Kestrel might be experienced in holding the camp.D. The entire family is welcome to the Kestrel Sundays23. What will the children do in the camp according to the passage?A. Visit the group leaders.B. Learn how to cooperate.C. Plant trees in the forest.D. Help elders to tell stories.BSome scientists will say it is impossible to read minds. They will also tell you that you can make educated guesses on what a person might be thinking or feeling. Perhaps there really is nothing mysterious about the power to read minds. Perhaps it is simply human sense based on observation and educated guesses after all, but that's really a useful ability to learn.Learn body language. How a person moves and holds their hands, and even what their eyes are doing are actually telling about what is going on inside their head. For example, pupils (瞳孔) tend to grow larger when you are interested in or excited about something. If you are talking to someone and making eye contact, finding their pupils are large and round, chances are that they are not feigning interest in the conversation. Someone biting their nails is probably nervous. Someone who folds their arms across their chest when they are not cold is probably trying to put a barrier between you and themselves.Learn to mentally put yourself in another' s place. Scientists have recently discovered that your brain has neurons (神经元) that become active when you watch someone do something the same as we did the action ourselves. So when you are able to open yourself to understanding how other people are feeling, you can figure out reasons and predict future actions,reactions, even thoughts.Sometimes you can use Extra Sensory Perception (ESP) (超感觉力) to read someone's mind. This does not mean you will literally be able to read their mind like a book. Instead, you will receive impressions or feelings, which are difficult to explain.To improve your ESP abilities, take up meditation (冥想). Because meditation helps enable you to purposely put your brain in a state of relaxed awareness, where you will be more successful in reading people and receiving impressions.Practice and combine all of these steps. You will soon find yourself able to read people's minds.24. What is the passage mainly about?A. The ways of reading people's minds.B. The steps of learning body language.C. The necessity of learning to read people’s minds.D. The relationship between mind and body language.25. What does the underline word "feigning" mean?A. Expressing.B. Pretending.C. Finding.D. Declaring.26. Why can you read someone's mind when you mentally put yourself in his/her place?A. You suddenly have the ability to understand his or her feeling.B. Your imagination ability and your past experience are combined.C. Some neurons m your brain improve your observation ability.D. Your past similar experiences make some neurons in your brain active.27. How does meditation help with mind reading?A. By making educated guesses on minds.B. By learning to make eye contact.C. By changing ESP abilities for the better.D. By strengthening impressions received.C"Stop all the rushing and screaming: too much excitement is bad for families. Kids are missing out on an essential life -relaxed down time, " says Dr. Charlotte Reznick."Parents work, and kids do scheduled activities - there' s little family time without pressure," says Reznick. "One parent is taking the son to a soccer game, and the other parent is taking the daughter to her swim meet. Then there's art class, baseball practice, extra tutoring, and more! By the time the family meet up for dinner, everyone is exhausted."All the rushing makes for a short temper. "When parents are reduced to shouting at their children to get them to listen, they lower their own self-esteem as well as losing the respect of their children," says Dr. Carl Pickhardt "While parents think it shows they' re serious about what they're saying, they are really just showing helpless desperation at not getting their way. "These days what kids are learning at school and from the outside is a lot greater than it used to be even just a generation ago."The problem is that stress-relieving activities - reading, taking walks or hot baths, watching the sunset and other activities are not even part of most kids' experience any more, " says Reznick."There are so many more social-interaction opportunities in our computer age, but not all of them promote meaningful connections, which is another potential outlet for stress, " she says.One way to relieve stress is a simple technique called "the balloon breath". It's a great way for everyone to become calm so that they can respond thoughtfully rather than just react.Here's how to do it. Imagine a deflated (来充气的) balloon in your stomach - about two to three inches below your navel (肚脐). Slowly breathe in to a count of l. . . 2. . . 3. . . and feel the lower belly expand, and flatten as you slowly breathe out to a count of l. ..2. . .3. . .28.

What is the function of “the balloon breath" according to the seventh paragraph?A. To make one cool down.B. To test one’s patience.C. To raise one’s awareness.D. To fill a balloon with air.31. What is the purpose of the author writing this passage?A. To tell educators to be patient.B. To advise parents not to make life too stressful for kids.C. To encourage kids to pursue creativity.D. To show that kids need patience and love from their parents.DOpera is an art form that celebrates the human voice. No other art form creates excitement and moves the heart in the way that opera does, especially when performed by a great singer. Opera is an important part of the Western classical music tradition. It uses music, words, andactions to bring a dramatic story to life. Opera started in Italy at the end of the 16th century and later became popular throughout Europe. Over the years, it has responded to various musicals, In recent decades, much wider audiences have been introduced to opera through modern recording technology. Some singers have become celebrities thanks to performing on radio, on TV, and in the cinema.However, in recent years, opera has been facing serious challenges. One current challenge to opera is economic. The shortage of money raises the broader question of how much should be paid to support opera singers and other artists. Society seems to accept the large salaries paid to business managers and the multi-million-dollar contracts given to sports athletes. But what about opera singers? Somehow, people have the idea that artists can be creative only if they suffer in poverty, but this is unrealistic. If artists, including opera singers, lack the support they need, valuable talent is wasted.Not only the shortage of money, but also the way money is managed in the opera world has led to hardships. Principal singers are generally paid performance fees once they complete a show. They typically receive nothing during the many weeks of rehearsal (排练) before a show starts.Another problem faced by opera is how to meet the demands of audiences who are influenced by popular entertainment. Pop singers are often judged as much on the basis of how they look as how they sound. These demands may be unrealistic and possibly harmful. Opera singers simply cannot make a sound big enough to fill a large theater or concert hall without a microphone if their body weight is too low. Emphasizing physical appearance over singing ability may cause audiences to miss out on the human voice at its best.There are no easy solutions to opera's problems and there are many different opinions about the value of opera. However, every year many young people register for music courses with hopes and dreams of developing their talents in this special art form. The fact that opera has survived many obstacles and continues to attract the rising generation shows that it remains a respected art form full of value.32. Which of the statements is TRUE according to the passage?A. Opera singers' life stories are dramatic.B. Opera will soon appear on TV and in filmsC. Opera fans thank celebrities for performingD. Opera develops by adapting to new conditions.33. What can we know from Paragraphs 2 and 3?A. Opera singers are financially insecure.B. Opera singers waste their valuable talent.C. Opera singers get paid before the show.D. Opera singers perform better if they are poor.34. What does the author try to say in Paragraph 4?A. Popular culture has had a positive influence on operaB, Audiences know best how opera should be performedC. Microphones should be used to make opera more enjoyableD. Opera singers' voices should be valued more than their looks.35. What would be the best title for this passage?A. The Economic Challenge to OperaB. Opera Faced with the DifficultiesC. Opera as Part of Popular CultureD. The Historical Context of Opera第三部分语言知识运用第一节完形填空Life in the Slow LaneI always seemed to be rushing through my life.

Not only were there sights that I had been missing, but I began to hear entire 58 all around me: birds singing , wind blowing and leaves rustling.59 one gives close attention to anything, even a blade of grass, it becomes a mysterious, beautiful and indescribably magnificent 60 in itself.41.

One day three mouses said proudly to each other that they each could drink more wine, so they decided to have a drinking contest. At last they both felt dizzy. One suggested, "Will anybody go to the wine cellar to fetch another bottle of wine?" The first stood up and down then fell to the ground. The other two laughed and said, "He was drinking and couldn't walk." The second stood up. He just made several steps and couldn't help thrown up. The third laughed hardly and then it was their turn. He stood up and made one step, two steps... Nothing is wrong. He went straight to the wine cellar but took a bottle of wine.

春秋战国上下五百余载，是中国历史上最充满活力的黄金时代，是“礼崩乐坏，瓦釜雷鸣；高岸为谷，深谷为陵”的剧烈变化时代。

依今人之说，那是个大毁灭、大创造、大沉沦、大崛起，从而在社会整体上大转型的时代，这使得那个时代的人无论是政治家、思想家，还是军事家、教育家，是侠，是士，其生命状态无一不是饱满昂扬奋进向上的，充溢着一种不可遏止的进取精神和非凡的创造力。

那是个讲究谋略的阳谋时代，所以智慧丛生色彩斑斓；那是个本色人生的时代，所以仕学争鸣侠隐飘逸，摇唇鼓舌皆成风流；那是个实力竞争的时代，所以强国富民为本，虚伪的文过饰非的理论无法泛滥；那是个深刻思索、创造思想、成就学问、铸造精神的时代，是中华文化的原生代，所以出现了学术思想百家争鸣的灿烂辉煌的景象。

在我们耳熟能详的中国伟人中，有一半多的伟人属于那个伟大的时代，政治、经济、哲学、文学艺术、科学、神秘文化……几乎所有基本领域，都在那个时代开山立宗并创造了我们民族精神的最高经典，不仅成为我们中华民族文化的源头，而且当之无愧地进入了人类文化的殿堂。

春秋战国时代是我国历史上政治变革最为活跃的时代，五霸迭兴，三家分晋，田氏代齐，七雄兴衰，此起彼伏。

在那个波澜壮阔的时代里，教育从戎与祀的礼制中挣脱出来，孔子私学，稷下学宫，最终实现“以法为教”“以吏为师”的学吏教育制度；文学形成了中国古典文学史上第一个黄金时代。

文艺作品林林总总，诗歌、辞赋、小说、散文皆为后世之滥觞，这时期有《楚辞》的铺陈抒情、浪漫想象；有《论语》《孟子》的雍容和顺、灵活善譬；有《庄子》的想象丰富、奇气袭人；有《韩非子》的锋利峭刻、研箴析理。
