我有一个梦想（节选）马丁·路德·金一百年前，一位伟大的美国人签署了《解放黑奴宣言》，今天我们就是在他的雕像前集会。

这一庄严宣言犹如灯塔的光芒，给千百万在那摧残生命的不义之火中受煎熬的黑奴带来了希望。

它之到来犹如欢乐的黎明，结束了束缚黑人的漫漫长夜。

然而一百年后的今天，我们必须正视黑人还没有得到自由这一悲惨的事实。

一百年后的今天，在种族隔离的镣铐和种族歧视的枷锁下，黑人的生活备受压榨；一百年后的今天，黑人仍生活在物质充裕的海洋中一个穷困的孤岛上；一百年后的今天，黑人仍然蜷缩在美国社会的角落里，并且，意识到自己是故土家园中的流亡者。

今天我们在这里集会，就是要把这种骇人听闻的情况公之于众。

就某种意义而言，今天我们是为了要求兑现诺言而汇集到我们国家的首都来的。

我们共和国的缔造者草拟宪法和独立宣言时，曾以气壮山河的词句向每一个美国人许下了诺言，他们承诺给予所有的人以不可剥夺的生存、自由和追求幸福的权利。

就有色公民而论，美国显然没有实践她的诺言。

美国没有履行这项神圣的义务，只是给黑人开了一张空头支票，支票上盖上“资金不足”的戳子后便退了回来。

但是我们不相信正义的银行已经破产，我们不相信，在这个国家巨大的机会之库里已没有足够的储备。

因此今天我们要求将支票兑现——这张支票将给予我们宝贵的自由和正义的保障。

我们来到这个圣地也是为了提醒美国，现在是非常急迫的时刻。

现在决非侈谈冷静下来或服用渐进主义的镇静剂的时候。

现在是实现民主的诺言的时候。

现在是从种族隔离的荒凉阴暗的深谷攀登种族平等的光明大道的时候，现在是把我们的国家从种族不平等的流沙中拯救出来，置于兄弟情谊的磐石上的时候，现在是向上帝所有的儿女开放机会之门的时候。

如果美国忽视时间的迫切性和低估黑人的决心，那么，这对美国来说，将是致命伤。

ARosie Dutton, a teacher from Relax Kids in Tamworth, UK, used two apples to show her students the often unseen but harmful effects of school bullying(校园欺凌). She posted the lesson on Facebook, where it's been shared more than 160,000 times.Rosie Dutton explained that during one of her classes she presented the children withtwo red apples. What the kids didn't know was that before the lesson, she had repeatedly dropped one of the apples on the floor. And yet, on the outside at least, both apples looked perfect.“I picked up the apple I'd dropped on the floor and started to tell the children how I disliked this apple,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either, so they should call it names too.”Some of the children looked at her as if she were “crazy”, but the students passed the apple around the circle, calling it names.Continuing the exercise, the teacher then passed the second apple around the circle. This apple, however, was show ered with words like: “Your skin is beautiful,” and “ what a beautiful colour you have.”Dutton then showed the students both apples once again, stressing that “there was no change, and both apples still looked the same.”Finally, Dutton cut both apples open. The apple that the class treated kindly looked fresh inside. But the other apple—the one they'd treated poorly —was bruised（瘀伤的) beneath its skin.“I think there was a light bulb moment for the children immediately,” Dutton said. “When people are bulli ed, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling. If we hadn't have cut that apple open, we would never have known how much pain we had caused it.”Dutton explained how important it is to teach children to stand up for one another, and to stop any form of bullying.“Let's create a generation of kind caring children,” the teacher wrote. “The tongue has no bones, but is strong enough to break a heart. So be careful with your words.”21.What had the teacher done to the first apple before the lesson?A.She had introduced it to the kids.B.She had coloured it brightly.C.She had made it look perfect.D.She had damaged it purposely.22.What does the underlined part “calling it names” (Para. 3) mean?A.Shouting at it.B.Making fun of it.C.Cheering for it.D.Saying rude things.23.What did the teacher tell the kids to do with the second apple?A.Drop it.B.Praise it.C.Ignore it.D.Respect it.24.What's the purpose of the teacher's using two apples in class?A.To draw the kids' attention.B.To explain her personal preferences.C.To help the kids understand the results of bullying.D.To make a comparison between them.BI can’t think of a better way of appreciating a new culture than by taking part in one of its festivals. You’ll find that some festivals are celebrated by an entire country, while others may be known only to a single city or region, but either way festivals play an important role in a certain culture. Just enjoy them!★ Tomatina — Bunol, SpainEvery last Wednesday in August, the town of Bunol is filled with tons of tomatoes in the world’s biggest food flight. Many people wear goggles during this hour of great fun, as the town becomes a red river.★ Boryeong Mud Festival — Boryeong, South KoreaFor two weeks in July, millions gather in Boryeong to experience the grey pools and slides. What began as a way to help sell the region’s mineral-rich mud has turned into a festive party with music and fireworks. The mud is usually only available in cosmetic products (化妆品), but here you can cake yourself in grey as you want. ★ Holi — IndiaHoli, the Festival of Colors, is a Hindu celebration full of joy and one of India’smost important holidays. During the day of the last full moon of the lunar month, usually late February or early March, the air is full of brightly colored powder (粉末). The festival is celebrated differently throughout the country, with bonfires and music, but the cheerful spirit is common among Hindu people around the world. ★ International Pillow Fight Day — WorldwideTens of thousands of people took part in the 4th annual International Pillow Fight Day on April 2,2013. From London to Vancouver to many other cities, the festival is held in more than 100 countries. So just bring a soft pillow in early April, and watch feathers fly.25.According to the author, ________.A. there should be festivals celebrated by the whole worldB. festivals give people the best chances to experience a cultureC. it’s usually hard for people to accept a diff erent cultureD. festivals in a certain culture often change with time26.We learn from the passage that ________.A. the town of Bunol in Spain is on a riverB. cosmetic products sell well on Boryeong Mud FestivalC. International Pillow Fight Day has a short historyD. Holi is the greatest festival for Indian people27.The passage is most likely to be found in ________.A. a personal diaryB. a technical reportC. a geography bookD. a travel magazineCFinding the Real YouPsychometric testing — personality testing — has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality typewhich stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “Pe ople who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprun g up. “It’s possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”So can we change our personality? “Your basic personality is fixed by the time you’re 21,” says Gill,“but it can be affected by motivation and intelligence. If you didn’t have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it’s why we’re seeing this trend for downshifting —too many people trying to fit in to a type that they aren’t really suited for.”Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you’ll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.28.The Myers-Briggs Type Indicator is based on the belief that __________.A. personality is largely decided from birthB. certain personality traits are commonC. some personality types are better than othersD. personality traits are various from time to time29.According to Dr. Gill, what is the problem with personality tests?A. The results could be opposite to what employers want.B. People can easily lie about their true abilities.C. Employers often find the results unclear.D. They may have a negative effect on takers.30.In Dr. Gill’s view, how easy is it to change your personality?A. It’s possible in your adult life.B. It’s easy if you have great motivation.C. It’s unlikely because it requires much energy.D. It’s difficult before the age of 21.31.What final conclusion does the author reach about the value of personality tests?A. They are of doubtful value to employers.B. They are not really worth doing.C. They can strengthen the idea we have of our abilities.D. They may encourage greater realism.DWelcome to your future life!You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.You walk into the kitchen. You pick up the milk, but a voice sa ys, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.It's time to go to work. In 2035, cars drive the mselves. Just tell your “smart car” where to go. On the way. You can call a friend using your jacket sleeve. Such “smart technology” is all around you.So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.”The Internet is one example. What will be the next?32.We can learn from the text that in the future ___________.A.people will never get oldB.everyone will look the sameC.red will be the most popular colorD.clothes will be able to change their pattern33.What can be inferred from Paragraph 4?k will be harmful to health.B.More drinks will be available for sale.C.Food in the grocery store will carry electronic information.k in the grocery store will stay fresh much longer.34.Which of the following is mentioned in the text?A.Cars will be able to drive automatically.B.Fridges will know what people need.C.Nothing can replace the Internet.D.Jacked sleeves can be used as a guide.35What is the text mainly about?A.Food and clothing in 2035.B.Future technology in everyday life.C.Medical treatments of the future.D.The reason for the success of new technology.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

育才学校学年度第二学期期末考试高一(一般班)语文一、现代文阅读（一）论述类文本阅读阅读下边的文字，达成以下小题。

陶诗的自然美陶诗的美在于真，也就是自然。

这同他的思想、生活和为人是完好一致的。

他作诗不存祈誉之心，生活中有了感想就诉诸笔墨，既无矫情，也不矫饰，全部照实说来，真率而又自然。

《五柳先生传》说：“尝著文章自娱，颇示己志，忘却得失。

”这表示了他的创作态度。

正如宋人黄彻所说：“渊明所以不可以及者，盖没心于非誉、巧拙之间也。

”陶渊明爱的是自然，求的是自然，自然就是他最高的美学理想。

朱熹说：“渊明诗所认为高，正在不待安排，胸中自然流出。

”这些话正道出了陶诗的风格特点。

陶渊明的诗和生活完好打成一片，他仿佛无心写诗，不过从生活中意会到一点道理，产生了一种感情，包含在心灵深处，一旦遇到外力的引发（如一片景色，一节古书，一件时势），便采纳了诗的形式，像泉水相同流溢出来。

陶诗纯以自然本色取胜，它的美是朴实美。

我们在陶诗里很难找到奇异的意象、夸张的手法和华美的词采。

如“种豆南山下”, “今日天气佳”,“秋菊有佳色”，全都理解如话，仿佛绘画中的白描，还有一种令人心旷神怡的神韵。

但是，假如不过是朴实平庸，不会产生激烈的艺术成效，陶诗的利处是朴实中见豪华，平庸中有瑰奇。

正如苏轼所说，“外枯而中膏，似澹而实美。

”陶诗所描绘的常常是最平时的事物，那些在他人看来平平庸淡的东西，一经诗人笔触，就给人以新鲜的感觉。

如《归园田居》(其五)“山涧清且浅，能够濯我足。

漉我新熟酒，只鸡招近局。

日入室中暗，荆薪代明烛。

”可是是极平时的一条山涧，一只鸡，一束照明用的荆薪，在陶渊明笔下，便有了盎然的生趣。

乡村生活的朴实，邻居的和蔼，以及乡下民俗的淳朴，全都表此刻纸上，给人以美的享受。

但是陶诗的语言不是未经磨炼和雕凿的，不过不露印迹，自然得很。

比如《杂诗》十二首频频写光阴的流逝，同一个意思用不一样的语句表达，都磨炼得十分精髓。

“掷”人而去的日月，不肯“待”人的光阴，“催”人老的四时，都被给予了生命。

育才学校2017—2018学年第二学期期末考试高一（实验班）物理试卷一、选择题（每题4分，共48分）1. 在力学理论建立的过程中，有许多伟大的科学家做出了贡献。

关于科学家和他们的贡献，下列说法中不正确的是( )A. 伽利略首先将实验事实和逻辑推理(包括数学推演)和谐地结合起来B. 笛卡儿对牛顿第一定律的建立做出了贡献C. 开普勒通过研究行星观测记录，发现了行星运动三大定律D. 牛顿总结出了万有引力定律并用实验测出了引力常量【答案】D【解析】试题分析：A、伽利略首先将实验事实和逻辑推理（包括数学推演）和谐地结合起来，标志着物理学的真正开始，故A正确；B、笛卡尔等人又在伽利略研究的基础上进行了更深入的研究，他认为：如果运动物体，不受任何力的作用，不仅速度大小不变，而且运动方向也不会变，将沿原来的方向匀速运动下去，因此笛卡尔对牛顿第一定律的建立做出了贡献，故B正确；C、开普勒提出行星运动三大定律，故C正确；D、万有引力常量是由卡文迪许测出的故D错误．本题选错误的，故选D．2. 关于物体的受力和运动，下列说法中正确的是( )A. 物体在不垂直于速度方向的合力作用下，速度大小可能一直不变B. 物体做曲线运动时，某点的加速度方向就是通过这一点的曲线的切线方向C. 物体受到变化的合力作用时，它的速度大小一定改变D. 做曲线运动的物体，一定受到与速度不在同一直线上的合外力作用【答案】D【解析】A、如果合力与速度方向不垂直，必然有沿速度方向的分力，速度大小一定改变，故A错误；B、物体做曲线运动时，某点的速度方向就是通过这一点的曲线的切线方向，而不是加速度方向，故B错误；C、物体受到变化的合力作用时，它的速度大小可以不改变，比如匀速圆周运动，故C错误；D、物体做曲线运动的条件是一定受到与速度不在同一直线上的外力作用，故D正确。

故选：D。

3. 狗拉雪橇沿位于平面内的圆弧形道路匀速行驶，以下给出的四个关于雪橇受到的牵引力F 及摩擦力F f的示意图(图中O为圆心)中正确的是( )A. B. C. D.【答案】C【解析】物体做曲线运动时，其线速度方向沿曲线上某点的切线方向，该题中，雪橇沿圆周运动到某点时，速度沿该点圆周的切线方向，所受的摩擦力F f方向一定与其线速度方向相反；由于雪橇做匀速圆周运动，所以它所受牵引力F和摩擦力F f的合力一定指向圆心，由此推知只有图C满足条件．故选C.4. 如图所示，在足够长的斜面上的A点，以水平速度v0抛出一个小球，不计空气阻力，它落到斜面上所用的时间为t1；若将此球改用2v0抛出，落到斜面上所用时间为t2，则t1与t2之比为( )A. 1∶1B. 1∶2C. 1∶3D. 1∶4【答案】B的时间与平抛运动的初速度有关，初速度变为原来的2倍，则运行时间变为原来的2倍．所以时间比为1：2．故B正确，ACD错误．故选B。

ARosie Dutton, a teacher from Relax Kids in Tamworth, UK, used two apples to show her students the often unseen but harmful effects of school bullying(校园欺凌). She posted the lesson on Facebook, where it's been shared more than 160,000 times.Rosie Dutton explained that during one of her classes she presented the children withtwo red apples. What the kids didn't know was that before the lesson, she had repeatedly dropped one of the apples on the floor. And yet, on the outside at least, both apples looked perfect.“I picked up the apple I'd dropped on the floor and started to tell the children how I disliked this apple,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either, so they should call it names too.”Some of the children looked at her as if she were “crazy”, but the students passed the apple around the circle, calling it names.Continuing the exercise, the teacher then passed the second apple around the circle. This apple, however, was show ered with words like: “Your skin is beautiful,” and “ what a beautiful colour you have.”Dutton then showed the students both apples once again, stressing that “there was no change, and both apples still looked the same.”Finally, Dutton cut both apples open. The apple that the class treated kindly looked fresh inside. But the other apple—the one they'd treated poorly —was bruised（瘀伤的) beneath its skin.“I think there was a light bulb moment for the children immediately,” Dutton said. “When people are bulli ed, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling. If we hadn't have cut that apple open, we would never have known how much pain we had caused it.”Dutton explained how important it is to teach children to stand up for one another, and to stop any form of bullying.“Let's create a generation of kind caring children,” the teacher wrote. “The tongue has no bones, but is strong enough to break a heart. So be careful with your words.”21.What had the teacher done to the first apple before the lesson?A.She had introduced it to the kids.B.She had coloured it brightly.C.She had made it look perfect.D.She had damaged it purposely.22.What does the underlined part “calling it names” (Para. 3) mean?A.Shouting at it.B.Making fun of it.C.Cheering for it.D.Saying rude things.23.What did the teacher tell the kids to do with the second apple?A.Drop it.B.Praise it.C.Ignore it.D.Respect it.24.What's the purpose of the teacher's using two apples in class?A.To draw the kids' attention.B.To explain her personal preferences.C.To help the kids understand the results of bullying.D.To make a comparison between them.BI can’t think of a better way of appreciating a new culture than by taking part in one of its festivals. You’ll find that some festivals are celebrated by an entire country, while others may be known only to a single city or region, but either way festivals play an important role in a certain culture. Just enjoy them!★ Tomatina — Bunol, SpainEvery last Wednesday in August, the town of Bunol is filled with tons of tomatoes in the world’s biggest food flight. Many people wear goggles during this hour of great fun, as the town becomes a red river.★ Boryeong Mud Festival — Boryeong, South KoreaFor two weeks in July, millions gather in Boryeong to experience the grey pools and slides. What began as a way to help sell the region’s mineral-rich mud has turned into a festive party with music and fireworks. The mud is usually only available in cosmetic products (化妆品), but here you can cake yourself in grey as you want. ★ Holi — IndiaHoli, the Festival of Colors, is a Hindu celebration full of joy and one of India’smost important holidays. During the day of the last full moon of the lunar month, usually late February or early March, the air is full of brightly colored powder (粉末). The festival is celebrated differently throughout the country, with bonfires and music, but the cheerful spirit is common among Hindu people around the world. ★ International Pillow Fight Day — WorldwideTens of thousands of people took part in the 4th annual International Pillow Fight Day on April 2,2013. From London to Vancouver to many other cities, the festival is held in more than 100 countries. So just bring a soft pillow in early April, and watch feathers fly.25.According to the author, ________.A. there should be festivals celebrated by the whole worldB. festivals give people the best chances to experience a cultureC. it’s usually hard for people to accept a different cultureD. festivals in a certain culture often change with time26.We learn from the passage that ________.A. the town of Bunol in Spain is on a riverB. cosmetic products sell well on Boryeong Mud FestivalC. International Pillow Fight Day has a short historyD. Holi is the greatest festival for Indian people27.The passage is most likely to be found in ________.A. a personal diaryB. a technical reportC. a geography bookD. a travel magazineCFinding the Real YouPsychometric testing — personality testing — has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality typewhich stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “People who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprung up. “It’s possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”So can we change our personality? “Your basic personality is fixed by the time you’re 21,” says Gill, “but it can be affected by motivation and intelligence. If you didn’t have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it’s why we’re seeing this trend for downshifting —too many people trying to fit in to a type that they aren’t really suited for.”Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you’ll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.28.The Myers-Briggs Type Indicator is based on the belief that __________.A. personality is largely decided from birthB. certain personality traits are commonC. some personality types are better than othersD. personality traits are various from time to time29.According to Dr. Gill, what is the problem with personality tests?A. The results could be opposite to what employers want.B. People can easily lie about their true abilities.C. Employers often find the results unclear.D. They may have a negative effect on takers.30.In Dr. Gill’s view, how easy is it to change your personality?A. It’s possible in your adult life.B. It’s easy if you have great motivation.C. It’s unlikely because it requires much energy.D. It’s difficult before the age of 21.31.What final conclusion does the author reach about the value of personality tests?A. They are of doubtful value to employers.B. They are not really worth doing.C. They can strengthen the idea we have of our abilities.D. They may encourage greater realism.DWelcome to your future life!You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way. You can call a friend using your jacket sleeve. Such “smart technology” is all around you.So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.”The Internet is one example. What will be the next?32.We can learn from the text that in the future ___________.A.people will never get oldB.everyone will look the sameC.red will be the most popular colorD.clothes will be able to change their pattern33.What can be inferred from Paragraph 4?k will be harmful to health.B.More drinks will be available for sale.C.Food in the grocery store will carry electronic information.k in the grocery store will stay fresh much longer.34.Which of the following is mentioned in the text?A.Cars will be able to drive automatically.B.Fridges will know what people need.C.Nothing can replace the Internet.D.Jacked sleeves can be used as a guide.35What is the text mainly about?A.Food and clothing in 2035.B.Future technology in everyday life.C.Medical treatments of the future.D.The reason for the success of new technology.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
