第Ⅰ卷 阅读题(共70分) 甲 必考题 一、现代文阅读(9分,每小题3分) 阅读下面的文字,完成1~3题 对马西亚航空公司370航班的搜索工作引起了公众对有关如何追踪飞机的诸多疑问,追踪飞机方位的一个重要手段就是借助雷达。

悉尼大学布鲁克博士表示,雷达的探测能力受到很多因素限制,例如距离、天气以及飞机的具体情况。

布鲁克称雷达是由发射机和接收器构成,发射机天线朝着一个特定的方向发射无线电信号,接收器负责探测信号行进途中遇到的物体反射的“回声”。

这种信号借助天线以短电磁能脉冲的形式发送,被称之为“脉冲”。

布鲁克说:“基于天线的朝向,雷达能够确定一个目标的方向。

”与目标之间的距离根据发射脉冲和接收回波之间的时间确定。

因为雷达信号一直以光速移动,因此能够准确测算出距离。

空中交通管制雷达的射束以每隔2秒或者3秒扫描一圈,回波显示在圆形显示屏上,被称之为“平面位置指示器”。

空中交通管制员或者电脑能够追踪到回波或者说根据屏幕上的光点确定飞机的飞行方向。

这种雷达被称之为“初级雷达”。

布鲁克指出:“初级雷达很少单独使用,因为空中的飞机实在是太多了。

现在,我们还会使用次级雷达。

次级雷达的编码脉冲序列发送给飞机,飞机上的异频雷达收发机产生一个编码回应信号,信号中含有与飞机有关的大量信息。

这些信息用于进行敌我识别。

” 空中交通管制员主要使用次级雷达追踪商业飞机的方位,只有在没有安装异频雷达收发机,收发机关闭或者破损情况下才会使用真正的雷达。

如果飞机上的异频雷达收发机被人切断,便很难判断空中交通控制中心的初级雷达屏幕上的光点究竟哪一个才是目标飞机。

布鲁克说:“这可能就是为什么370航班的异频雷达收发机在管制责任从一个空中交通管制中心移交给另一个中心时关闭。

This past year has been one of the hardest for me. I felt I was stuck in a position that had nothing to do with what I wanted to do with my life. In January, after two years of being together, my boyfriend left me.I read your blog every morning as I drink my coffee at work, but it wasn't until this March that I told myself "no more negativity" as you taught readers in your blog.Since then I've got into new habits at work to keep my energy positive. When people walk in the front door, I'm the first face they see, so I smile big when I say "good morning" to them, especially on Mondays. Instead of waiting for someone to ask me for help, I offer it with an open mind. The CEO noticed my change and offered me the executive assistant position that I wanted.One of the biggest things I've taken to heart from your blog is changing my opinions on my job. Yes, it was not an important position, but when I was passionate (热情的)about it, I could make my life fulfilling.All in all, I have to thank you somehow for having the passion to help others because it truly is inspiring to me.

If you plan to visit St. Louis Zoo, you can go there ______.A. at 8:30 am in summerB. at 5:30 pm in autumnC. on ChristmasD. on New YearCFrom Japan to Indonesia, a certain kind of pop culture is very hot. But it doesn’t come from Hollywood —it’s Hallyu (韩流), the wave of Korean pop culture that has washed over Asia. It has influenced everything from music to television. And thanks to the Internet and social media, it’s now spreading worldwide.South Korea produces all types of entertainment, the most popular being music, soap operas and films. What makes Hallyu so hot in Asia? One reason is that its products are of high quality and much cheaper than western products. Another reason is that eastern cultures are similar to each other, although there are language differences.Korean pop music, or “K-pop”, ranks the first everywhere. Fans love the songs and the attractive stars. Companies like SM Entertainment, JYP Entertainment and YG Entertainment help many K-pop stars, such as Super Junior, Big Bang and Rain, to succeed. They are not only popular in Asia but also enjoy popularity in the West. In 2011, Big Bang’s mini-album Tonightreached the top 10 on U.S. Tunes Top Pop Albums. When SM Entertainment took their 2010 world tour to Los Angeles, only 30 percent of the 15,000 fans were Korean. Half of the audience wasn’t even Asian!One important reason for the success of Hallyu is simply the Internet.A little more than 10 years ago, Korean soap operas, movies and music reached the outside world quite slowly. They began in Korea, and then gradually spread outward, appearing in its neighboring countries where local TV and radio companies would play them. Now they are played around the world online at the same time.YouTube is another major way to get Korean entertainment to fans everywhere. It is an inexpensive and validway for artists to introduce their work to a larger audience. In 2010 the YouTube channels for the top three Korean entertainment groups together had nearly 800 million views from 225 different countries.8.Hallyu is very hot in Asia partly because________.A. the quality of South Korea’s products is highB. the culture is the most fashionable in the worldC. languages in Asia are similar to each otherD. South Korea’s products are the cheapest in Asia9.The author shows the popularity of K-pop in the West_______.A. in order of spaceB. by listing reasonsC. by giving examplesD. in order of time10.What does the underlined word “valid” (in Para. 5) mean?A. slowB. necessaryC. uselessD. successful11.What would be the best title for the passage?A. K-pop Ranks the First EverywhereB. YouTube Helps Korean Cultures SpreadC. Hallyu Makes Waves across the WorldD. Korean Soap Operas Are Growing in PopularityDThe biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference (电磁干扰). The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.RTC.A, an organization which advises the aviation (航空)industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights.Currently, rules on using these devices are left up to individual airlines. And although some airlines prevent passengers from using such equipment during take-off and landing, most are unwilling to carry out a total ban, given that many passengers want to work during flight.The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.12. What is said about the over 100 aircraft incidents in the past 16 years?A. They may have been caused by the damage to-the radio systems.B. They were proved to have been caused by the passengers portable computers.C. They were suspected to have resulted from electromagnetic interference.D. They may have taken place during take-off and landing.13.Why is it difficult to predict the possible effects of electromagnetic fields on an airplane 's computers?A. Because it is extremely dangerous to conduct such research on an airplane.B. Because research scientists have not been able to produce the same effects in labs.C. Because it remains a mystery what wavelengths are liable to be interfered with.D. Because experts lack adequate equipment to do such research.14. Few airlines want to perform a total ban on their passengers using electronic devices because_______A.they don't believe there is such a danger as radio interferenceB. the harmful effect of electromagnetic interference is yet to be provedC. most passengers refused to take a plane ,which bans the use of radio and cassette playersD. they have other effective safety measures to fall back on15. The passage is mainly about_________.A. a possible cause of aircraft incidentsB. a new rule for all airlinesC. effective safety measures for air flightD. the disadvantages of electronic devices第二节任务型阅读(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。

河南省南阳市方城县第一高级中学(五校)高二12月联考语文试卷 Word版无答案.pdf

2015年秋期五校第二次联考 高二语文试题 第I卷 阅读题 一、现代文阅读(9分,每小题3分) 阅读下面的文字,完成1—3题。

魏晋风度的文化内涵 魏晋时期是地道的乱世,因此文人的普遍心理即是思治,这就促使魏晋名士开始探索宇宙自然与人生本体的关系,并开始追求新的思辨哲理。

在这种背景下,“文的觉醒”与“人的觉醒”时代到来,思想开放与自由论辩的风气成为当时文人名士的生活常态,而“魏晋风度”正是在这种氛围中应运而生的。

“魏晋风度”所代表的这种文化,有何晏、王弼首发其端,他们酷爱庄老,而起清谈之风;发展至“竹林七贤”时代,这一群体成为魏晋风度的典型代表。

“竹林七贤”即阮籍、嵇康、山涛、刘伶、阮成、向秀和王戎等七人,他们都是当时的文人名士,他们大都崇尚老庄之学,对社会现实有着无比清醒的认识。

然而,由于身处乱世,虽有济世报国之才,却没有值得辅佐的明主,只好用形骸放浪、不拘小节的行为来掩饰内心的痛苦,用不合事宜的言行来表达对朝政的不满。

魏晋名士用自己的言行、诗文等外化行为使自己的人生艺术化,具体表现为不同常人的放旷、真率与智慧。

这种艺术的人生是自然的,是个人的真实处境与心境的流露。

正是由于残酷的政治迫害和生命的命悬一线,使得魏晋士人的人生充满了无尽的忧虑恐惧和深重的哀伤。

这构成了魏晋风度深刻沉重的一面。

玄学是这个时期文人的思想灵魂与源泉。

他们用老庄的哲学思想解释儒家经典。

在空谈中探讨自然与人本体的关系,探求更本质的人生意义,将关注点从无能为力的政治转向了自身存在价值的讨论。

《周易》《老子》和《庄子》被奉为玄学经典。

玄学给两汉以来保守腐朽的儒学注入了新鲜的血液,给中国的哲学文化领域带来了一种不同以往的自由、理性、思辨的哲学思维,同时是魏晋名士们自我肯定的强烈自信与率性自由的外化表现。

魏晋名士以率性率真的人性来品味玄趣,由此生发出一种由外知内、以形显神的美学观念,这使他们开始转向对自然山水的热爱与探究,以空灵之心审视山水自然的大道之美。

河南省方城县第一高级中学2015届高三12月月考英语试题及答案

方城县第一高级中学2015届高三12月月考英语试题第一节阅读理解(共20小题;每小题2分,满分40分)阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项,并在答题卡上将该项涂黑。

AAs we know, many teen celebrities(名人) feel and think that having a slimmer figure can do great good to them. But, does size really matter? Are teenage fans trying hard to become like their celebrity idols(偶像)? Do celebrities really have the power to influence people, especially teenagers?For the longest time, many parents blame teen idols for influencing the way their kids act. Have you noticed how teens idolize the celebrities these days? Even, their personal affairs are being followed by kids these days. Take for example the case of Lindsay Lohan of Mary Kate Ashley. They are definitely famous teen stars. But, since they are trying to project an image to satisfy a lot of people in show business, their health and body suffer. Many kids are aware of this problem. But they are easily influenced by these celebrities to exercise and eat less.It is a fact that the media, and especially famous teen celebrities, can influence people powerfully. But teenagers are easily influenced because teenage years are the period when our personality and identity developments take place. Teens watching TV shows and reading magazines are easily pulled into the dieting and harmful eating habits because the media have some ways to pull these acts. They use thin models and celebrities to endorse(做广告宣传) products or to star in an up-and –coming shows or movies. With fierce competition, celebrities are forced to eat less and do extreme exercise routines to get the roles or offers that come their way.Living in today’s time and generation is a bit disturbing to a lot of parents. Media, especially as well as the celebrities, have a very powerful influence to drive teenagers to good or bad. It’s good that we can control ourselves to avoid bad things from happening. If not, parents should really be aware and guide their teens to determine what’s in ad what’s out.21. From the passage we can find Lindsay Lohan .A. lives an unhealthy lifestyleB. lives a rich and happy lifeC. doesn’t get any exerciseD. sets a good example for teenagers22 According to the writer, why are teenagers easily influenced by some TV shows?A. They are tired of school.B. Their celebrity idols appear in many TV shows.C. They’re in their development period.D.

Parents’ responsibilities.B. Advice on self-control.C. Bad influences of celebrities.D. Media’s bad influences.BThroughout history, gold has been a sign of purity, beauty and power. Calling something golden means it has great quality and value. For example, the golden rule is possibly the world's most widespread moral rule. It says people should treat others the way they themselves would like to be treated. Every major religion has its own version of this idea.The golden ratio is found in art, architecture and nature. It describes a rectangle with a length about one and one-half times its width. Objects using this ratio in their design seem to please the eye more than others.Philosophers(哲学家)have their own golden idea. The golden mean says moderation in all things is the best way to live one's life. It is an idea linked to the Ancient Greek philosopher Aristotle. Similar thoughts exist in Buddhism and Confucianism.(哲学思想)Ancient Greek myths told of a time long ago when people lived in peace and happiness. Poets called it the Golden Age. A golden age now describes a historical period of great artistic, scientific or economic progress. It can even recall a time of success and popularity for an industry. For example, the nineteen thirties and forties were called the Golden Age of Radio.You may have heard the proverb silence is golden. This means silence is of great value. It is sometimes better to say nothing than to speak.You might say your child was good as gold when he behaved well at school. British writer CharlesDickens used this expression in eighteen forty-three. He was describing the child Tiny Tim in the book "A Christmas Carol."In nineteen thirty-seven, American playwright Clifford Odets wrote a play called "The Golden Boy." This expression describes a young man who has many good qualities and a bright future.You might tell someone you are golden when that person does something very well.Gold digger is another description. But this does not say something nice about a person. A gold digger is someone who seeks to marry a rich person because he or she is only interested in that person's money.Maybe you like old songs from the nineteen fifties or sixties that are still well known and popular today. These are called golden oldies. In the nineteen eighties and nineties, an American television comedy series told about four older women living in Miami, Florida. The Golden Girls often dealt with social issues in a funny way.Today, most older people look forward to reaching their golden years. This is when hard-working people can retire to a life of ease and fulfillment.25 .According to the “golden ratio”, which of the following objects in the most pleasant to see?26 .The article mainly tells us ___A .the value of gold B. the expressions with “gold”C .the history of gold industry D. the purity, beauty and power of gold27 .Which of the following statements is made out of place?A. The beauty of tolerance and kindness comes from the Confucianism philosophical thought ,such as Golden Mean.B. At the beginning of the twenty first century computer reached its Golden Age.C. She only dates guys with money. She’s a Gold Digger.D. My grandfather is 65 and is looking forward to reaching his Golden Ages28 .What we can infer from the passage is that ___A. all the expressions in the article are positive descriptionB. the “golden mean” is an idea linked to the Ancient Greek philowpher AristotleC. the “golden oldies” refers to the popular soon in the 1950s or 60s which are not well-know todayD. in their golden yearw, older people can still work hard before their retireCAfter moving to the United States, immigrant groups trying to fit in tend to choose high-calorie, fatty foods in an attempt to appear more American, a new study finds. That's one reason why immigrants approach U.S. levels of obesity within 15 years of moving to America.The researchers also did an experiment that measured whether or not the threat of appearing un-American influenced respondents' food choices.After being questioned about their ability to speak English,75 percent of Asian-Americans identified a typical American food as their favorite. Only 25 percent of Asian-Americans who had not been asked if they spoke English did the same.When their American identity was called into question during a follow-up study, Asian-American participants also tended to choose typical American dishes, such as hamburgers and grilled cheese sandwiches, over more Asian fare. In that experiment, 55 Asian-Americans were asked to choose a meal from a local Asian or American restaurant. Some participants were told that only Americans could participate in the study. Those who chose the more typical American fare ended up consuming an extra 182 calories, including 12 grams of fat and seven grams of saturated fat(饱和脂肪)."People who feel like they need to prove they belong in a culture will change their habits in an attempt to fit in," said Sapna Cheryan, an author of the study and assistant professor of psychology at the University of Washington. "If immigrants and their children choose unhealthy American foods over healthier traditional foods across their lives, this process of fitting in could lead to poorer health," Cheryan added.Social pressures, the study concluded, are at the heart of the problem. "In American society today, being American is associated with being white. Americans who don't fit this image even if they were born here and speak English feel that pressure to prove that they're American," said Cheryan.29 According to the survey, _____.A. Asia-Americans care less about their health.B. 25 percent of Americans like junk food.C. choosing food is related to Asian-American’s situationD. immigrants are forced to eat junk food.30 The underlined word “fare” in Paragraph 3 most probably means “_____”A. food offered as a mealB. a person taking a taxiC. money spent on foodD. an arranged thing to do31 According to Sauna Cheryan, ________.A. what immigrants have done is ridiculousB. American traditional foods are healthierC. immigrants risk their health in order to fit inD. American culture affects immigrants deeply32 Which of the following should take the blame for the bad eating habit?A. The situation of employmentB. The traditional cultureC. The American governmentD. The pressures from societyDStaying silent can be just as powerful as the words you mean to say, like when the act of hugging will be more comforting than saying, “Sorry for your loss.”Another time when silence is golden is when you are unsure of what to say. If you are confused about your own feelings concerning a matter, it’s best to stay quiet until you are more certain because more harm can be done by revealing false or exaggerated feelingsChoose silence instead of blurting out ‘in-the-moment’ feelings that are hurtful and not really how you feel in the grand scheme of things. When you feel the urge to say an unkind thing, take a few breaths and think of the possible consequences of your words.Silence can be your best friend during negotiations. Say your piece, then close your mouth, and let the other person come to their own conclusions. Your silence shows that one, you are confident in what you just said, and two, you respect the other person enough to hear what they have to say.Sometimes silence is the best and most timely solution because the other person is not in a position to hear what you have to say. For example, when a friend needs for you to listen to her problems, but she is unable to accept your advice at that moment.Practice being silent at work when you don’t have anything meaningful to contribute. Unless you can elevate the conversation by pointing out something interesting, missing, or beneficial, it’s best to just observe and learn.Finally, silence is golden when you don’t want to engage in a fool’s argument. As some squabbles will never be resolved, one must agree to disagree.However, there will be times in your life where you will need the power of your voice, the voice within you that wants and needs to be respected and appreciated.33 .The passage mainly tells us about ___A. when to stay silentB. why to stay silentC. how to stay silentD. whether or not to stay silent34 .What is the best to do during negotiation?A. Grasp every chance to say more than the otherB. Close your mouth and just listen to the otherC. Say what you could and draw a conclusionD .Speak out your own points and let the other speak out theirs35 What does the underl ined word “elevate” most probably mean?A.startB. concludeC. interrupt D .cancel七选五根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

河南省方城一高高二12月月考语文试题Word版含答案试卷说明:一、现代文阅读(9分,每题3分)阅读下面的文字,完成1—3题。

人类正面临生物入侵威胁生物入侵是指某种生物从本来的分布区域扩散到一个新的地区,在新的区域里,其后代可以繁殖、扩散并维持下去。

如何防止和抵御生物入侵已经成为各国科学家们密切关注的重大研究课题。

关于生物入侵的历史可追溯到很久以前,但对生物入侵的研究历史并不很长。

1958年爱尔通出版了《动植物入侵的生态学》一书,才奠定了入侵生物学的基础框架,并预见到生物入侵的数量和危害程度会大量增加。

全球入侵物种计划(GISP)是1997年建立的。

它是应80个国家和联合国代表的共同要求而成立,专门应对生物入侵的国际组织。

事实上,近十年来有关有害生物入侵和扩散危害的报告引起了众多国家的高度重视。

据美国普渡大学研究人员的调查,在美国印第安那州低收入的公寓楼内,约50%的公寓有德国小蠊危害。

我国也同样如此,20世纪中期被称为“洋蟑螂”的德国小蠊入侵我国,如今已成为城市主要害虫。

前两年加拿大“一枝黄花”在上海蔓延后影响多种本土植物物种的保存。

本年,上海又首次发现原产美洲,卵有剧毒且又凶猛的雀鳝淡水鱼,幸好专家表示雀鳝淡水鱼不适合在上海地区的水温和水质等自然条件下保存繁衍。

生物入侵所带来的经济损失惊心动魄。

据1999年美国前总统克林顿在签发总统令时提到,按照一些专家的估计,生物入侵每年对美国造成的损失高达1230亿美元。

而我国,据2002年报告,仅11种主要入侵生物每年所造成的损失即高达574亿元,生物入侵所造成的总体损失可能达到数千亿元人民币。

我国生物学家徐汝梅认为:20世纪50年代,人们意识到化学污染对环境的巨大影响及其对人类健康的巨大威胁。

而从90年代后,人们开始关注人类所面对的另一巨大威胁——生物入侵。

可以说,随着全球经济一体化进程的加速及交通运输业的飞速发展,货物及人员在全球各地区间快速、大量流动,自然会给作为载体的外来生物提供广阔的迁移空间和异地入侵的环境。

第Ⅰ卷阅读题(共70分)甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题对马西亚航空公司370航班的搜索工作引起了公众对有关如何追踪飞机的诸多疑问,追踪飞机方位的一个重要手段就是借助雷达。

悉尼大学布鲁克博士表示,雷达的探测能力受到很多因素限制,例如距离、天气以及飞机的具体情况。

布鲁克称雷达是由发射机和接收器构成,发射机天线朝着一个特定的方向发射无线电信号,接收器负责探测信号行进途中遇到的物体反射的“回声”。

这种信号借助天线以短电磁能脉冲的形式发送,被称之为“脉冲”。

布鲁克说:“基于天线的朝向,雷达能够确定一个目标的方向。

”与目标之间的距离根据发射脉冲和接收回波之间的时间确定。

因为雷达信号一直以光速移动,因此能够准确测算出距离。

空中交通管制雷达的射束以每隔2秒或者3秒扫描一圈,回波显示在圆形显示屏上,被称之为“平面位置指示器”。

空中交通管制员或者电脑能够追踪到回波或者说根据屏幕上的光点确定飞机的飞行方向。

这种雷达被称之为“初级雷达”。

布鲁克指出:“初级雷达很少单独使用,因为空中的飞机实在是太多了。

现在,我们还会使用次级雷达。

次级雷达的编码脉冲序列发送给飞机,飞机上的异频雷达收发机产生一个编码回应信号,信号中含有与飞机有关的大量信息。

这些信息用于进行敌我识别。

”空中交通管制员主要使用次级雷达追踪商业飞机的方位,只有在没有安装异频雷达收发机,收发机关闭或者破损情况下才会使用真正的雷达。

如果飞机上的异频雷达收发机被人切断,便很难判断空中交通控制中心的初级雷达屏幕上的光点究竟哪一个才是目标飞机。

布鲁克说:“这可能就是为什么370航班的异频雷达收发机在管制责任从一个空中交通管制中心移交给另一个中心时关闭。

AEducation is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life. In some modern countries it has for some time been fashionable to think that by free education for all-whether rich or poor, clever or stupid-one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees refuse to do what they think to be "low" work, and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment tounderstand that the work of a completely uneducated farmer is far more important than that of a profess-or, we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns.In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one's work. Only sucha type of education can be considered valuable to society.1. From the passage we can conclude that______.A. education can settle all of the world's problemsB. free education for all probably leads to a perfect worldC. free education won't help to solve social problemsD. all the social problems can't be solved by education2. The writer wants to prove that _____.A. our society needs all kinds of jobsB. our society needs free education for allC. a farmer is more important than a professorD. people with university degrees refuse to do what they think to be "low" work3. According to the passage _____.A. work with hands is dirty and shamefulB. work with hands is low workC. work with hands is the most importantD. we can't regard work with hands as low work4. The purpose of education is _____.A. to choose a system of educationB. to prepare children mainly for their future workC. to let everyone receive education fit for himD. to build a perfect world5. The passage tells us about _____.A. system of educationB. means of educationC. value of educationD. type of educationBDo you sometimes argue about what seems to you to be a simple fact? Do youargue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit?If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant’s trunk said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear as he touched the animal’s tusk. The fourth, who took hold of the elephant’s tail insisted that it was like a rope. The fifth man said it looked like a tree as he put his arms around one of the elephant’s legs. The sixth, who was tall and got hold of theelephant’s ears, sai d it was like a huge fan.Each man’s idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water in the third. Now put your left hand in the ice water. Put your right hand in the hot water. After thirty seconds, put both hands in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it’s hot.6. What makes people think about simple facts differently?A. The fact that simple facts differ from one another.B. The fact that people have different experience in the same simple fact.C. The fact that people often disagree with one another.D. The fact that it’s hard to make up one’s mind about simple facts.7. The writer’s advice is that ________.A. we should never think about simple factsB. we should never judge something with a one-sided viewC. we should not agree about simple factsD. we must learn from the six blind men8. What’s the main idea of this passage?A. People often judge something according to their own experience.B. People often agree about simple facts.C. It’s hard for a person to make up his mind about a simple fact.D. Don’t care too much about simple facts.CHOLIDAY FUN AT THE POWERHOUSE500 HAR RIS STREET ULTIMO •TELEPHONE (02)9270111Join in the holiday fun at the Powerhouse this month linked to our new exhibition, Evolution & Revolution Chinese dress 1700s to now.

Researchers have found that people missing their goals perform much better in the long run. That is because they gain more knowledge from their failures than their successes and the lessons are more likely to stay longer in their minds.“We found that the knowledge gained from success was often fleeting while knowledge from failure stuck around for years,” said professor Desai, who led the study. “But companies often ignore failure. Managers may fire people or turn o ver the whole workforce while they should treat the failure as a learning opportunity.”Prof Desai compared the flights of the space shuttle Atlantis and the Challenger. During the Atlantis flight last year, a piece of insulation (绝缘体) broke off and damaged the left solid rocket booster (助推火箭) but didn’t influence the program. There was little investigation. The Challenger was launched next and another piece of insulation broke off. This time the shuttle and its seven–person crew were destroyed. The disaster led to a major investigation resulting in 29 changes to prevent future disasters.The difference in response in the two cases came down to this Atlantis was considered a success and the Challenger a failure.“Despite crowded skies, airlines are extremely reliable,” he said. “The number of failures is extremely small. And past researches have shown that older airlines, those with more experience in failure, have a lower number of accidents.”Prof Desai doesn’t recommend finding out failure in order to lear n. Instead, he advises organizations to analyze small failures to collect useful information rather than wait for major failures.13. Why did experts pay little attention to the problem of Atlantis?A. Because it worked perfectly.B. Because the right booster was still OK.C. Because nothing serious happened then.D. Because fewer people died in the flight.14. Fewer accidents happen to older airlines in that ________.A. their planes couldn’t fly high in the skyB. they gained much from experience in failureC. their planes were often checked by the expertsD. they were unpopular among passengers15. The passage is written mainly to ________.A. show failure is a better teacher than successB. explain why Challenger failedC. introduce something about Prof DesaiD. tell managers how to achieve success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。

While other kids ate candy for breakfast, I had to have cereal, eggs and toast. Others had cokes and candy for lunch, while we had to eat a sandwich. As you can guess, my supper was different from the other kids'. But at least I was not alone in my suffering. My sister and two brothers had the same mean mother as I did.My mother insisted on knowing where we were at all times. She had to know who our friends were and what we were doing. We had to wear clean clothes every day. Other kids always wore their clothes for days. We reached the height of disgrace because she made our clothes herself, just to save money.The worst is yet to come. We had to be in bed by 9:00 each night and up at 7:45 the next morning. So while my friends slept, my mother actually had the courage to break Child Labor Law. She made us work. I believed she lay awake all night thinking up mean things to do to us. Through the years, our friends' report cards had beautiful colors on them, black for passing, red for failing. My mother, however, would merely be content with black marks. None of us was allowed the measure of being a dropout.She forced us to grow up into educated and honest adults. Using this as a background, I'm now trying to bring up my three children. I'm filled with pride when my children think I am mean because now I thank God every day for giving me the meanest mother in the world.36.From the passage we can learn that the writer's mother was ______.A.not generous at all B.very strict with her childrenC.very mean with money matters D.very cruel to her children37.Which of the following things did the writer hate to do most?A.Eating differently from other kids. B.Wearing clean clothes made by mother.C.Going to bed early and getting up early. D.Letting mother know where they were.38.It can be inferred from the passage that ______.A.the writer worked hard and got good grades in studiesB.mother was punished for breaking the Labor LawC.all the other kids studied better than the writerD.the writer's family lived a miserable life39.The passage was written in a way of ______ tone.A.hateful B.ridiculous C.critical D.HumorousBBursting into the classroom from recess(学生的课间休息), 15 children take their seats and face the woman they know as Ms. Yang.“What day is it today?” she asks, in Mandarin (普通话) Chinese.“Confucius’ birthday!” the fifth graders shout in Mandarin.“Why do we celebrate Confucius’ birthday?”“Because he’s the greatest teacher in the history of China!”exclaims a brown-haired girl. She too is speaking Mandarin.English is rarely hear d in Lisa Yang’s class at the Chinese American International School (CAIS), despite the fact that few students are native speakers of Mandarin. The United States is actively trying to increase the group of students in “critical languages” such as Mandarin. The students at CAIS are way ahead in such a trend. Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.Mandarin Chinese is suddenly hot in American schools. As China becomes the world’s leading economy sometimes this century, schools in the U.S. are scrambling to add Mandarin to their roster of foreign languages or expand Chinese programs already in place.“It really is almost unprecedented(无前例的). People are looking at China as a force to be reckoned with…And to ensure that the U.S. has the ability to conduct trade, and to work with the Chinese, certainly having an understanding of Chinese language and culture is an advantage,” said Marty Abbott of the American Council on the Teaching of Foreign Languages (ACTFL) (美国外语教学协会).To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U.S.Robert Liu remembers his first two years in an American classroom. It was not an easy adjustment. “In China, students respect their teachers,” he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U.S.40. Which of the following is not true according to the passage.A.Understanding Chinese language and culture is helpful to work with the Chinese.B. chinese-language programs have met trouble during the development.C. Many other American schools do the same as the CAIS founded 25 years ago.D. A lack of trained Mandarin Chinese teachers is a problem for the programs.41. What kind of problem is the most difficult to adjust in teaching Chinese in America?A.To adapt themselves to American lifestyles.B.To communicate with the American students.C.To get along well with the American students.D.To be fit for the cultural differences in teaching styles.42. The meaning of the underlined word “scrambling” is similar to .A.climbingB.rushingC.changingD.beating43. It can be learned from the passage that _____. .A.the studen ts in Lisa Yang’s class usually speak ChineseB.there are few American students in Lisa Yang’s classC.we celebrate Confucius’ birthday because he’s the greatest teacher in the history of ChinaD.in America the students don’t respect their teachersCIn 2006, young businessman Blake Mycoskie went to Argentina on vacation. He went back to America with a business plan that would help thousands of children. While on vacation, Mycoskie saw children who couldn’t afford even one pair of shoes. Their feet suffered cuts, and he wanted to help. He noticed the shoes that Argentinean farmers wore. Inspired by those simple shoes with rope bottoms, he had an idea. Mycoskie wanted to give these children the shoes they needed. He gave his new plan a name --- TOMS. For every pair of shoes he sold, he would give a new pair to a needy child. One for one.It was a slap(耳光) in the face to traditional business practices. How could he make a profit by giving so much away? However, he started selling shoes out of his apartment. When he had sold 10,000 pairs of shoes, he returned to Argentina with 10,000 pairs to give away.Although often taken for granted, shoes play an important role. Children without shoes easily injure their feet. They can catch a disease through soil that could make them sick or slow down their growth. Some children can’t attend school without shoes becausethey are part of the uniform.TOMS, together with other charity organizations, continues to find communities that will get benefit. Since that f irst “shoe drop” in Argentina, TOMS has contributed new shoes to communities in Asia, Africa, and Central and South America.Mycoskie’s special principle is all about giving. This has attracted a lot of media attention, saving money on marketing. When pe ople hear about TOMS’ purpose, they buy the shoes and then share the story with a slogan of “shoes for a better tomorrow”.44. When he was on vacation, Blake Mycoskie ________.A. created a new kind of shoes with rope bottomsB. wanted to donate money to people in needC. found children suffering from a lack of shoesD. gave 10,000 pairs of shoes to Argentineans45. What are the reactions of other businessmen to TOMS?A. They envied Mycoskie for being able to sell so many shoes.B. They wondered how Mycoskie could manage it.C. They asked Mycoskie to stop doing this immediately.D. They felt sorry for Mycoskie’s having to give away so much.46. All the following facts show that shoes are important EXCEPT that ________.A. they cure diseases caught from soilB. they are part of the school uniformC. they prevent children’s feet from being injuredD. children may not grow normally without them47. How can Mycoskie give away so much but still earn money?A. He has a very persuasive slogan.B. He has special principle of giving.C. He has friends working in the media.D. He gets help from the media and customersDOver the years I've been teaching my grandchildren about a simple but powerful concept—the ant philosophy. I think everybody should study ants.They have an amazing four-part philosophy, and here is the first part: Ants never quit. If they're headed somewhere and you try to stop them, they'll look for another way. They'll climb over, or around. They keep looking for another way to get where they're supposed to go. What a great philosophy.Second, ants think summer all winter. That's an important perspective. You can't be so childish as to think summer will last forever. So ants are gathering their winter food in the middle of summer.The third part of the ant philosophy is that ants think winter all summer. That is so significant. During the winter ants remind themselves, “This won't last long;we'll soon be out of here.” And on the fi rst warm day, the ants are out. If it turns cold again, they'll dive back down, but then they come out on the first warm day. They can't wait to get out.And here's the last part of the ant philosophy. How much will an ant gather during the summer to prepare for the winter? All he possibly can. What an incredible philosophy, the “all-you-possibly-can” philosophy.Wow, what a great lecture to attend—the ant seminar!48.Which of the four parts of the ant philosophy means “look ahead”?A.The last part B.The third part. C.The second part D.The first part.49.The fourth paragraph is mainly talked about______.A.Stay positive B.Spare no effort C.Never give up D.Do all you can50.Which of the following might be the best title for the text?A.The Ant Life B.The Ant Philosophy C. The Ant Teamwork D.The Ant University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。

2015年秋期五校第二次联考高二语文试题第I卷阅读题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1—3题。

魏晋风度的文化内涵魏晋时期是地道的乱世,因此文人的普遍心理即是思治,这就促使魏晋名士开始探索宇宙自然与人生本体的关系,并开始追求新的思辨哲理。

在这种背景下,“文的觉醒”与“人的觉醒”时代到来,思想开放与自由论辩的风气成为当时文人名士的生活常态,而“魏晋风度”正是在这种氛围中应运而生的。

“魏晋风度”所代表的这种文化,有何晏、王弼首发其端,他们酷爱庄老,而起清谈之风;发展至“竹林七贤”时代,这一群体成为魏晋风度的典型代表。

“竹林七贤”即阮籍、嵇康、山涛、刘伶、阮成、向秀和王戎等七人,他们都是当时的文人名士,他们大都崇尚老庄之学,对社会现实有着无比清醒的认识。

然而,由于身处乱世,虽有济世报国之才,却没有值得辅佐的明主,只好用形骸放浪、不拘小节的行为来掩饰内心的痛苦,用不合事宜的言行来表达对朝政的不满。

魏晋名士用自己的言行、诗文等外化行为使自己的人生艺术化,具体表现为不同常人的放旷、真率与智慧。

这种艺术的人生是自然的,是个人的真实处境与心境的流露。

正是由于残酷的政治迫害和生命的命悬一线,使得魏晋士人的人生充满了无尽的忧虑恐惧和深重的哀伤。

这构成了魏晋风度深刻沉重的一面。

玄学是这个时期文人的思想灵魂与源泉。

他们用老庄的哲学思想解释儒家经典。

在空谈中探讨自然与人本体的关系,探求更本质的人生意义,将关注点从无能为力的政治转向了自身存在价值的讨论。

《周易》《老子》和《庄子》被奉为玄学经典。

玄学给两汉以来保守腐朽的儒学注入了新鲜的血液,给中国的哲学文化领域带来了一种不同以往的自由、理性、思辨的哲学思维,同时是魏晋名士们自我肯定的强烈自信与率性自由的外化表现。

魏晋名士以率性率真的人性来品味玄趣,由此生发出一种由外知内、以形显神的美学观念,这使他们开始转向对自然山水的热爱与探究,以空灵之心审视山水自然的大道之美。

正是这种超越形的束缚的情怀,使自然山水被赋予了人性化的灵性与无穷的玄趣。

另一方面,他们把在政治理想上的绝望转向文学艺术,寻求精神上的解脱。

在“神韵”这一独特的审美追求指导下,魏晋时期的文学、绘画、书法等艺术门类都不同程度地呈现出一片空前繁荣的景象。

魏晋风度是魏晋名士人生态度、处世方式和人格精神的具体展现,反映了魏晋时期文人士大夫阶层的价值取向,它不仅在那时具有广泛的时代意义,对后世中国传统文人的文化哲学和思想,也产生了深远的影响。

魏晋士人通过自身在乱世中真实而坚定的实践,以前所未有的气魄和感染力,融入了中国文人的灵魂深处。

一方面,魏晋风度造就了中国文人清高的气质与清醒的思辨;另一方面,它为后世处于低谷困境的文人知识分子提供了精神的慰藉与平静,并得以发展为自省与放旷的生活理念,用以追求人本质的回归、精神的解放和个性价值的真正体现。

1.下面对“魏晋风度”文化内涵的表述,不正确的一项是()A.魏晋名士用言行、诗文将自己的人生艺术化,具体表现为放旷、真率与智慧。

B.融入了中国文人的灵魂深处,造就了文人自古至今清高的气质和清醒的思辨。

C.超越形的束缚,品味玄趣,生发了一种由外知内、以形显神的美学观念。

D.以自由、理性、思辨的哲学思维,表现出自我肯定的强烈自信与率性自由。

2.以下不是“魏晋风度”形成的原因的一项是()A.魏晋乱世,文人思治,他们开始探索宇宙自然与人生本体的关系。

B.魏晋文人清醒认识现实,怀才不遇,统治者对其进行残酷的迫害。

C.魏晋时期的文人酷爱老庄,以玄学作为自己的思想灵魂和源泉。

D.魏晋名士放浪形骸,追求个性,寄情山水,醉心文学艺术。

3.下面的说法符合原文意思的一项是()A.玄学是魏晋名士的精神支柱,他们以此来关照自我,探寻苦难社会中人生的价值和意义。

B.魏晋士人厌倦了社会的动荡,对黑暗政治不满,只好转而研究老庄之学,借此麻痹自己。

C.“人的觉醒”促进了当时思想解放和自由论辩风气的形成,这是魏晋风度的突出表现。

D.魏晋风度以自省与放旷的生活理念使后世落魄的文人知识分子获得了精神的真正解放。

寒夜星光徐树建韩晓龙日日夜夜盼望着能回家过年,说起来已有好几年没回家跟妈妈团聚了,因为这几年都是在狱中度过的,今年刚刑满释放。

可是,他不敢回家,因为妈妈托人捎过话来:“要想我原谅你,除非年三十晚上满天星光。

”要知道寒夜的天幕上,向来只有几颗闪着冷光的星星,哪有满天星光,妈妈这是在明确表明态度:拒绝儿子回家。

而妈妈之所以如此绝情,是因为韩晓龙伤透了她的心。

几年前韩晓龙开的小餐馆因为使用过期变质肉类,让一桌食客食物中毒进了医院,其中一名老人还感染了并发症送了命,韩晓龙也因此坐了大牢。

韩晓龙不怨妈妈心狠,爸爸早逝家境极度贫寒,要是没有乡亲们的帮助,他们娘儿俩的日子不可想象,所以,妈妈经常教育儿子要心存感恩回报社会,千万不能忘本。

可是,自个儿让妈妈失望了。

有家不能回,韩晓龙只好在县城内租一小间房子住了下来,靠什么生活呢?幸亏妈妈曾经教过他扎孔明灯的手艺,于是韩晓龙晚上扎灯,白天在热闹的地方卖灯。

当他扎好第一个灯时,忍不住想起小时候跟妈妈一起扎灯的情景,那时候虽然贫穷,但母子情浓,虽苦也甜,这么一想,热泪一下子夺眶而出。

年根的生意还算不错,韩晓龙忙得不可开交,有位大商户甚至一下子订了100只孔明灯。

韩晓龙快乐极了,没日没夜地赶做,终于按时完工交货。

除夕这天,过年的气氛越发浓厚,空气内处处弥漫着好闻的味道,韩晓龙心里却越发凄凉,想了半天无事可干,出租屋内恰好还有几只孔明灯,索性顶着寒风拎了灯上街,准备卖了后再买瓶酒,一醉方休。

刚站了一会儿,身后就有人大声叫道:“给我一只灯!”生意开张了,韩晓龙心内一喜,但抬头一看,却掉头就走,甚至还小跑起来,因为那人他认识,是他初中同学大山,还是住对门的邻居。

他没脸见到他们。

大山气冲冲地提高嗓门吼道:“韩晓龙,你个孬种,你难道一辈子不见人?”韩晓龙只好停住脚步,大山走过来,恨恨地又说:“我恨不得抽你两下,你小子混啊!走,跟我回去,明天就过年了,家家户户团圆,你就不想跟你妈团圆?”韩晓龙低头小声说:“大山,我怎么不想啊,可你也不是不晓得我妈撂过的话,她说除非年三十晚上满天星光才肯原谅我,你说我怎么回去?”大山叹口气,说:“我们住对门,你们家里的情况我爸妈是最了解的,所以叫我来找你回去。
