高中英语学习材料***鼎尚图文理制作***东北育才学校高中部2014-2015学年度高一年级下学期第五次独立练习英语科试卷答题时间:50分钟满分:100分阅读理解第一节(共10小题;每小题2.5分, 满分25分)阅读下列短文,从每篇短文后各题所给的A、B、C、D四个选项中选出最佳选项,并在答题卡上将该项涂黑。

AOne of my neighbors used to have a beautiful tree in her front yard. Her dad had planted it for her when it was nothing more than a twig and several years later it started to shoot towards the sky with amazing speed. Soon it blessed her with cooling shade in the summer and glorious, golden leaves in the fall.When the two-day snowstorm struck our town, heavy snow fell on the tree’s branches that were still full of leaves. The weight split that lovely tree down the middle. It was so sad seeing half of it laying on the ground after the storm. When I talked to my neighbor later, she said that the damage had been too much and that the entire tree would have to be cut down. Thankfully she had saved a few saplings(树苗) from it that she hoped to replant in the future.Still, it was a shock to drive by her house the other day and see nothing but a stump in her front yard. I missed that tree. I missed its beauty, its leaves shinning in the afternoon sun. I missed seeing its limbs reach towards the heavens. I thought that the stump would be a sad reminder of its loss for a long time to come. My wonderful neighbor, though, had another plan. When I drove by her home today I saw a tiny bird feeder sitting on that stump and a colorful songbird having its dinner. It was such an affirmation of life. It was such a joy to see. I could feel my heart smile.Life by its very nature is a mixed bag. It hands us both beauty and tragedy, love and loss, pleasure and pain. What we do with it, however, is up to us. We can let it split us in two, or we can use even its hardest times to make our souls stronger and our hearts more loving. We can spend it complaining or we can use it to help others.1. We know from the first paragraph that _____.A. the tree grew very slowly.B. the tree showed its beauty and benefits.C. the author’s neighbor was good at planting trees.D. the tree was so strong that it could bear any weight.2. The author’s neighbor left a stump in her front yard to use it as_____.A. a good reminder.B. a seat after dinner.C. a place to feed birds.D. a beautiful sculpture.3. What does the author mainly want to show in the passage?A. Life has beauty and tragedy.B. Life consists of pain and suffering.C. Life should be pleasant rather than painful.D. Life is determined by our attitude towards it.BWhen most of us look at our hands, we might notice that we need to clean, or stop biting our fingernails, and that’s about it. But if you ask a doctor, he can see a whole lot more. Everything from poor diet and stress to serious kidney (肾) problems can be revealed by a glance at your fingernails.There are about 30 different nail signs that can be associated with medical issues, though may indicate more than one problem, according to Dr.Amy Derick, a clinical instructor of dermatology at Northwestern University.Here are five of the things a doctor can tell about your health based on your fingernails.1. People who aren’t eating well and lack vitamin or dietary may have thinner than normal nails, which are more likely to break.2.Horizontal (水平的) lines are associated with serious physical stress. They frequently occur in people who have gone through chemotherapy(化疗).They can also occur after some illnesses, injuries, or with severe malnourishment(营养不良).Interestingly, there may be an altitude connection too. They’ve also been found in people who dove 1,000 feet and others who participated in an Everest exploration.3. Vertical (垂直的)lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they’re commo nly associated with aging.4. When people lack iron, their nails can turn spoon-like. Instead of curving down and covering the finger normally, they ’ll start to rise up on the sides and front, like the part of a spoon that holds liquid.5. Kidney and live r problems can create “half-and-half nails”, where one part of the nail is white and the other part dark or pink, according to Derick.Doctors note that because disease diagnosis is complex and some symptoms can be associated with different diseases, you should always see a medical professional if you are concerned about something you notice.4. What is the main idea of the passage?A. Doctors can tell us something about our health by looking at our nails.B. We should see a doctor if we find nails in bad condition.C. A famous doctor in the USA conducted an interesting research.D. If we don’t want to get ill, we need to clean and stop biting our fingernails.5. If we don’t eat well or regularly, our fin gernails may ________.A. become harder than normal nails.B. become thinner than normal nails.C. become “half-and-half” nails.D. have horizontal and vertical lines.6. Who will have horizontal lines on the nails ?A. A cancer patient who has received normal treatment.B. Hungry African children suffering from severe malnourishment.C. An explorer who had reached Zhangjiajie in Hunan Province.D. A patient with serious illness, like kidney and liver problems.7. Which of the following best describes the nails that show people lack iron?A. The nails are thinner and more likely to break.B. The nails will curve down and cover the fingers.C. The nails will start to rise up on the sides and front.D. The nails will change their colours on the surface.CAs life expectancy increases nowadays, the average person lives well beyond the age of retirement. As a result, the elderly make up an ever-increasing percentage of society, which makes it more important than ever for a real effort to be made in improving the lives of senior citizens.One way to deal with the situation would be to ensure that the elderly have enough money on which to live. Obviously, when a person stops working, they still require a source of income to cover their basic needs such as food, accommodation and heating. A clear solution to the problem is for the government to make sure that the state pension is adequate for these needs.Steps should also be taken to overcome the health problems the elderly face. The government should also provide access to the best health care available, which may necessitate paying for residential homes where the elderly can have round-the-clock nursing, or, at the very least, providing medication free of charge to all people over a certain age.The lives of old people could be improved if attempts were made to address the problem of social isolation. If we organised trips for the elderly to community centres, visits from social workers their problem of loneliness can be reduced a lot which marks the lives of so many old people living alone and far from their families.One final suggestion, which would help enormously, is to change the attitude of the community towards its older members, who are all too often seen as a burden on society and dismissed as having little to do with modern life. We need to be taught from an early age to respect the views of old people, and appreciate their broader experience of life. This would help society as a whole, and encourage appreciation of the role that old people can still play today.8. What can be inferred from Paragraph 3?A. All the elderly can enjoy free medication.B. The nurses can take good care of the elderly.C. The elderly are in face of health problems.D. The health care available to the elderly is good.9. The underlined word “address” in Paragraph 4 probably means_________.A. find outB. deal withC. put downD. pick up10. According to the last suggestion, the old people_________.A. should be respected by all of usB. have to gather more life experienceC. may be regarded as our heavy burdenD. must change their attitude to the community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。

长郡中学高一语文暑假自主学习作业本(二十一)(含参考答案)

高中暑假自主学习作业本·高一年级语文语文作业二十一【考查内容】本节考查内容有:词语的用法、标点的用法、修辞手法、语序、图文转换、文言文(非史传类议论性散文)阅读、古代诗歌鉴赏、《六国论》的默写。

【知识梳理】文言文断句技巧做文言文断句题时,我们要本着“句不离段、段不离文”的基本原则,要对文章内容进行整体理解,顾及前后文,弄清写了什么内容,想表达什么意思。

在此基础之上再来推敲怎样断句。

一、找名代,定句读阅读中,要随时标出文段中的重要的名词,特别是专有名词,如人名、地名、事名、物名、官名、族名、国名、器物名、动物名、植物名、朝代名、官职名等。

这些名(代)词常在句中作主语或宾语,在它们的前后往往要进行断句。

第一人称:吾、我、予、余、朕、孤、寡人、臣、仆、妾等。

第二人称:尔、汝(女)、卿、若、乃、子、君、公、阁下、陛下、足下等。

第三人称:彼、之、其。

代谈话或为文所及的第三者,不仅代人,还可以代事代物。

近指代词:是、此、斯、兹等。

远指代词:彼、夫、其等。

疑问代词:人——谁、孰、何等。

事——奚、胡、曷(何)、安、焉等。

二、找虚词,定句读文言文,多用虚词来表达语气或感情。

一些议论性语段,借助虚词就会使断句变得更容易。

1.句首词(1)发语词:夫、盖、唯、惟、且、且夫……(2)敬谦副词:窃、请、敬……(3)时间词:向之、顷之、未几、已而、斯须、既而……(4)疑问词:何、安、岂、岂非、其……(5)复句关联词:虽、虽然、纵、纵使、向使、假使、苟、故、是故、则、然则、或、况、而况、且、若夫、至于、至若、于是……以上词语常用于一句话的开头。

在它们的前面一般要断开。

2.句末词也、矣、焉、耳等经常用于陈述句末尾;乎、为、与(欤)、邪(耶)等经常用于疑问句末尾;哉、夫等经常用于感叹句末尾。

其后面一般要断开。

【注意】复音虚词:有所、无所、有以、无以、以为、何所、孰若、至于、足以、何以、然则。

需保持完整,不能点断。

三、找对话标志,定句读文言文中对话、引文常常用“曰”“云”“问”“言”“道”(注意省略)等动词来判断人物的对话,进行断句。

材料一央视纪录片《我在故宫修文物》的热播,让文物修复师这个有点冷门的职业成为大家顶礼膜拜的对象。

儒雅睿智的钟表修复师王津喜提“故宫男神”称号,吸引越来越多的网友想去故宫拜师学艺。

8月30日,国家级非遗项目古钟表修复技艺第三代传承人王津在成都参加活动,分享故宫修钟表的那些事儿。

当他展出了一小段宫廷钟表修复完成之后的视频,清脆悦耳的报时声音,潺潺流水的仿真造型,让全场观众情不自禁地鼓掌,向大国工匠致敬。

1977年,王津来到故宫博物院文保科技部从事文物钟表修复与保护工作,与此同时,故宫第一代钟表复师徐文磷的儿子、第二代钟表修复师徐芳洲正式退休。

站在徐芳洲先生的工作台前,探索着使用对方留下的工具,王津静下心来,对抗时间在钟表上留下的痕迹,成为一个“修复时间”的“魔法师”。

择一事,“钟”一生。

王津在多个演讲中这样概括自己的职业生涯。

工艺繁复的钟表,钟爱一生的职业,同时,用坚持、匠心和技艺与时光抗衡。

用43年的岁月,坚持做一件事——修复钟表,传承技艺,王津的工作是与时间为友,静下心后,慢慢就不觉得枯燥了。

“透过文物,你可以看见前人的匠心精神,也可以窥见一个时代的兴衰更迭。

”从事钟表修复工作39年之后,2017年,因为纪录片《我在故宫修文物》的热播,儒雅睿智的王津突然变成“网红”,出门不仅经常会被人认出,还收到了录制综艺节目的邀约。

不过,王津对自己的“走红”非常淡然:“谢谢大家的喜爱,故宫的文物比我更加吸引人,吸引大家的是我手里的钟表,那是几代人修复的成果。

”43年来,王津修复的各类文物钟表多达300多件,其中修复过最为复杂的数十件馆藏钟表一级文物。

在王津看来,钟表修复比较枯燥,要想修好一件馆藏古钟,耗时少则两个月,多则一年,只有真正喜爱这项事业的人,才可能耐得住寂寞。

高中英语学习材料(灿若寒星*制作整理)东北育才学校高中部2014-2015学年度高一下学年独立练习英语科试卷答题时间:50分钟满分:100分第二部分:阅读理解第一节(共10小题;每小题2.5分, 满分25分)阅读下列短文,从每篇短文后各题所给的A、B、C、D四个选项中选出最佳选项,并在答题卡上将该项涂黑Passage OnePresident Coolidge’s statement, “The business of America is business,” still points to an important truth today-that business institutions have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions posses this great prestige?One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected.Competition protects the freedom of the individual by ensuring that there is no monopoly (垄断) of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Actually, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many businesses compete for the customers’ dollar, they cannot afford to treat them like inferiors or slaves.A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, that democracy in preserving freedom.Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic (贵族的) idea of inherited privilege.1. The statement “The business of America is business” probably means “________”.A) The business institutions in America are concerned with commerceB) Business problems are of great importance to the American governmentC) Business is of primary concern to AmericansD) America is a great power in world business2. Americans believe that they can realize their personal values only ________.A) when given equality of opportunityB) through doing businessC) by protecting their individual freedomD) by way of competition3. Who can benefit from business competition?A) Honest businessmen.B) Both businessmen and their customers.C) People with ideals of equality and freedom.D) Both business institutions and government.4. Government is believed to differ strikingly from business in that government ischaracterized by ________.A) its absolute control of powerB) its function in preserving personal freedomC) its role in protecting basic American valuesD) its democratic way of exercising leadership5. It can be inferred from the passage that the author believes ________.A) Americans are more ambitious than people in other countriesB) in many countries success often depends on one’s social statusC) American businesses are more democratic than those in other countriesD) businesses in other countries are not as competitive as those in AmericaPassage ThreeThe appeal of advertising to buying motives can have both negative and positive effects consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.Sometimes advertising is intentionally misleading. A few years ago a brand of bread was offer to dieters (节食者) with the message that there were fewer calories (热量单位,大卡) inevery slice. It turned out that the bread was not dietetic (适合于节食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.6. Advertising can persuade the consumer to buy worthless products by ________.A) stressing their high qualityB) convincing him of their low priceC) maintaining a balance between quality and priceD) appealing to his buying motives7. The reason why the bread advertisement is misleading is that ________.A) thin slices of bread could contain more caloriesB) the loaf was cut into regular slicesC) the bread was not genuine breadD) the total number of calories in the loaf remained the same8. The passage tells us that ________.A) sometimes advertisements really sell what the consumer needsB) advertisements occasionally force consumers into buying things they don’t needC) the buying motives of consumers are controlled by advertisementsD) fire insurance is seldom a worthwhile investment9. It can be inferred from the passage that a smart consumer should ________.A) think carefully about the benefits described in the advertisementsB) guard against the deceiving nature of advertisementsC) be familiar with various advertising strategiesD) avoid buying products that have strong emotional appeal10. The passage is mainly about ________.A) how to make a wise buying decisionB) ways to protect the interests of the consumerC) the positive and negative aspects of advertisingD) the function of advertisements in promoting sales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。

AHistorians usually just study great things that happened in the past time, but Drew Faust has made history! On February 11, 2007, Faust was named president of Harvard University. She is the first woman to hold the position in the school’s 371-year history.“I am a historian,” she said. “I’ve spent a lot of time thinking about the past, and abou t how it shapes the future. No university in the country, perhaps the world, has as remarkable a past as Harvard’s.”“And our common enterprise (事业) is to make Harvard’s future even more remarkable than its past. That will mean recognizing and building on what we already do well. It will also mean recognizing what we don't do as well as we should, and not being satisfied until we find ways to do better.”It is her great desire for improvement and willingness to try out new ideas that have given Drew s uccess in a world controlled by men. “This is a man’s world, my girl, and the sooner you learn that, the better off you’ll be.” Drew Faust recalls her mother telling her this when she was young, but she didn’t accept it.Faust grew up in a well-off fam ily in Virginia’s Shenandoah Valley in the 1950s. Even then, she was a trailblazer (先驱). A conversation with her family’s black handyman (零工) and driver inspired her to write a letter, on school notebook paper, to President Dwight Eisenhower.She asked that he should help bring US citizens together in the south, a much divided part of the country at the time.“Drew Faust is a historian with her eyes on the future,” said Susan Graham, a professor of Harvard. Many of the university’s school s said that they believe Harvard will have a brighter future under the leadership of Drew Faust.1. Why does the writer say Drew Faust has made history?A. Because she is a president.B. Because she is a historian.C. Because Harvard has a remarkable past.D. Because she is the first woman to be president of Harvard University.2. What do we know about historians?A. They are usually women.B. They are usually presidents of universities.C. They are usually born in well-off families.D. They usually study great things that happened in the past.3. What did her mother mean by saying “This is a man’s world, my girl...”?A. To tell her to do things as a girl should do.B. To ask her to be well-off.C. To encourage her to do man’s work.D. To expect her to be a historian.BIn America, Virginia Beach has all the elements of a classic seaside resort(度假胜地): brilliant beaches, a lively boardwalk, plenty of restaurants and nightspots, and amusement rides sure to appeal to kids. Many believe Virginia Beach is at its best in the off-season, when the town is less crowded but the weather is still mild.Meanwhile, some safety tips should be followed, to enjoy the happiness and excitement the beach offers.The number one safety tip concerns ocean safety: pay attention to Flag conditions posted on the lifeguard stands. Lifeguard post a red flag to warn when the ocean water is dangerous. Take them seriously! Tourists from land-locked regions are particularly easily attracted by the magic of the waves. However , a calm ocean can become risky without warning. Make sure you swim near a lifeguard. Swimming without lifeguard protection is almost five times as great as drowning at a beach with lifeguards.Never swim alone. Many drownings involved single swimmers. When you swim with someone else, if one of you has a problem, the other may be able to get help, including signaling for assistance from others.Don’t fight the current. The facts show that some 80% of rescues by lifeguards at ocean beaches are caused by currents. These currents are formed by surf and gravity, because once surf pushes water up the slope of a beach, gravity pulls it back. This can create concentrated rivers of water moving offshore. If you are caught in a rip (撕裂的)current, don’t fight it by trying to swim directly to shore. Instead, swim parallel to shore until you feel the current relax ,then swim to shore. Most rip current are narrow and a short swim parallel to shore will help bring you to safety.4.When coming to Virginia Beach, children cannot enjoy the happiness of______.A. walking on the road made of woodB. joining the nightspotsC. Riding a horse or a pumper carD. Skiing in the sea5. Many people believe the best time to visit Virginia Beach may be____.A. After autumn school term beginningB. In the summer vocationC. During the Christmas holidayD. In the cold winter6. From the passage we can know ____.A. one in five persons swimming in the sea is drownedB. if one with lifeguard were drowning, five persons without lifeguard would beC. some 80% people drowning by the currents are rescued by lifeguardsD. some 20% drowning by the currents are rescued by lifeguards7. The passage mainly tell us ____.A. Virginia Beach has all the elements of a classic seaside resortB. the happiness and excitement the beach offersC. some safety tips when swimming in the seaD. the dangers for tourists from land-locked regions to swim in the seaCThe creative projects of World Food Program (WFP) focused on preventing hunger from taking hold in the future and breaking the cycle of hunger. Here are some of the ways in which we work to prevent hunger in the future:School MealsAs well as directly addressing hunger, School Meals projects encourage families to keep their children in school and help them build better futures. If children aren’t hungry they will concentrate on their lessons. With a solid education growing children have a better chance of finding their own way out of hunger. These projects benefit girls especially. For more information: /schools meals.Food for Assets(有用的人)WFP’s Food for Assets projects provide the hungry with food to lay the foundation for a better tomorrow. When poor farmers no longer have to worry about the next meal ,they have the time and energy to build irrigation(灌溉)systems that can increase production. Similarly, Food for Training projects allow the poor to devote time to learning skills that will sustain(维持)them economically in the future. For more information: /food-assets.HIV/AIDSWFP uses its food rations(配给) to reduce the blow of HIV and AIDS. The agency distributes(分发)its rations to people living with HIV and AIDS, so they can keep providing for their families for longer and have time to transfer vital knowledge and skills to the growing number of AIDS children--the next generation of food providers in developing countries. For more information: /hiv-aids.Purchase for ProgressWFP buys large amounts of food in developing countries. It has this purchasing power and uses it to help poor farmers contact reliable markets where they can get competitive prices for their produce. With secure markets, farmers will be encouraged to produce more and innovate(创新).The knock-on effect is producing more food for everyone. For more information: www.wfp.ofp/purchase-progress.8.The text is written with the purpose of ____.A. seeking solutions to some hot issuesB. introducing some of WFP’s projectsC. raising money for the people in needD. calling readers’ attention to the poor9.AIDS children can benefit from food rations in that___.A. they no longer go hungryB. they can take care of their parentsC. they don’t have to worry about foodD. they can learn more skills from their parents10.By buying large amounts of food in developing countries, WFP aims to ____.A. help farmers to increase their incomeB. encourage farmers to produce more foodC. introduce new ways of farming to farmersD. motive farmers to plant different kind of crops.信息匹配(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的最佳选项。
