What is the purpose of the World Games? What's the difference between the World Games and the Olympic Games? _50 _the Olympic Games, the World Games have a rather _51_ history.In 1981, the first World Games were held in Santa Clara.Since then, in the year following the Olympics, some of the world's best athletes _52_ in their common search for _53_ at the world Games. There are usually 25 to 35 _54_ at the WorldGames, The events at the World Games are not part of the Olympics or ones were part of the Olympic Games.Many events at the World Games _55_ as Olympic events, like weightlifting and badminton.They got their start as events at the World Games _56_ being moved into the Olympics.Just like the Olympics, the World Games also have _57_ competitions.These competitions get the sport the chance to be seen and the chance to become medal events. The World Games are _58_ tied to the Olympic Games because the International Olympic Committee is the sponsor of the International World Games Association.The International Olympic Committee has decided that the number of Olympic participants is _59_ 10,500.The new policy means that no World Games competitions will be _60_ the Olympics any time soon. This year, the World Games were held in Taiwan.Some events, like softball, _61_ be Olympic sports but were dropped and now are _62_ for the World Games.The World Games look like a perfect supplement and _63_ ground for future Olympic Games.So next time you get a chance to watch the World Games, you may want to pay attention as it could be the future, or maybe even _64_. 50.A.As for B.But for C.Because of D.Compared with 51.A.early B.young C.long D.ancient 52.A.unite B.lie C.result D.participate 53.A.fame B.excellence C.wealth D.knowledge 54.A.games B.sports C.events D.matches 55.A.end up B.start on C.break off D.come up 56.A.after B.since C.before D.unless 57.A.international B.intense C.fair D.exhibition 58.A.loosely B.somewhat C.closely D.partly 59.A.amounted to B.limited to C.added to D.reduced to 60.A.moved into B.engaged in C.held in D.established in 61.A.had to B.seemed to C.happened to D.used to 62.A.good B.available C.helpful D.convenient 63.A.competing B.playing C.training D.camping 64.A.focus B.truth C.hope D.historySection B Directions: Read the following four passages.Each passage is followed by several questions or unfinished statements.For each of them there are four choices marked A, B, C and D.Choose the one that fits best according to the information given in the passage you have just read.(A) The temperature of the sun is over 5000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center.The sun is so much hotter than die earth that matter can exist only as a gas, except at the core.In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core.However, no one really knows, since the center of the sun can never be directly observed. Solar astronomers do know that the sun is divided into five layers or zones.Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core.The first three zones are regarded as the sun's atmosphere. But since the sun has no solid surface, it is hard to tell where the atmosphere ends and the main body of the sun begins. The sun's outermost layer begins about 10000 miles above the visible surface and goes outward for mllions of miles.This is the only part of the sun that can be seen during an eclipse(日食) such as the one in February 1979.At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun's rays. The corona is a brilliant, pearly white, filmy light, about as bright as the full moon.Its beautiful rays are a sensational sight during an eclipse.The corona's rays flash out in a brilliant fan that has wispy spikelike(一束束穗状)rays near the sun's north and south poles.The corona is thickest at the sun's equator. The corona rays are made up of gasesstreaming outward at tremendous speeds sad reaching a temperature of more than 2 million degrees Fahrenheit.The rays of gas thin out as they reach the space around the planets.By the time the sun's corona rays reach the Earth, they are weak and invisible. 65.Matter on the aim can exist only in fee form of gas because of the sun's ___. A.size B..age C.location D.temperature 66.All of the following are parts of the sun's atmosphere EXCEPT the ___. A.corona B.chromosphere C.photosphere D.core 67.According to the passage, as the corona ra5,'s reach -die plaasts, they become ___. A.hotter B.clearer C.thinner D.stronger 68.Which of 'die following do the paragraphs following the passage most likely discuss? A.The remaining layers of the sun. B.The evolution of the sun to its present form. C.The eclipse of February 1979. D.All the above.(B)The Best Rice Cookers ☆☆☆☆Tefal Automatic 2W3 Classic Rice Cooker One of the largest rice cookers on the market, with a 2-litre capacity (容量)(up to 12 servings).It looks "rather utilitarian", but gives "the least sticky results" and its removable power cord means it can be taken outdoors or to the table.It comes with eight recipes and once cooking is completed it automatically switches to "keep-warm mode".Price; $29.99.Call 0800-616413 for stockists.☆☆☆ Keiswood Rice Cooker and Steamer RC310 A "stylish looking machine with a heavy glass lid and a steam tray for steaming fish and vegetables.It cooks up to ten portions of rice (l.8-litre capacity), and produces "good results" although the rice tends to get sticky on the bottom layer.It keeps the rice warm once cooking is completed, but the power cord is not removable.Price:$34.99.Call 01705-392333 for stockists.☆☆☆Zojurushi Rice Cooker / Warmer NDAQ �C N10W This cooker has a one �C litre capacity (five portions of rice) and keepsrice warm for up to 12 hours after cooking.

A.low B.high C.above average D.reasonable C Warning: reading too much Cinderella to your daughter may damage her emotional health in later life. A paper to be developed at the international congress of cognitive psychotherapy(认知心理疗法) in Gothenburg suggests a link between the attitudes of women abused by their parents and early exposure to the wrong sort of fairy tales. It says girls who identified with Cinderella, Rapunzel and Beauty in Beauty and the Beast were more likely to say in destructive relationships as adults. The theory was developed by Susan Darker Smith, a psychotherapist at the University of Derby. She interviewed 67 female abuse survivors and found that 61 put up with severe abuse because they believed they could change their partners with patience, composition and love. The same view was taken by male survivors who had been abused as children. Hardly any of the women in a control group, who had not experienced abuse, thought they could change their partners in this way. The same view was taken by male survivors who had been abused as children. These women and men said they would leave a relationship rather than put up with abuse from a partner. Ms Darker Smith found the abused women were much more likely to identify with Cinderella and other submissive female characters in fairytales, who were later rescued by a stranger prince or hero. Although most girls heard the stories, damage appeared to be done to those who adopted the characters as role models. “They believe if their love is strong enough they can change their parents’ behaviors,” she said.” Overexposure in children to stories that emphasize the transformational qualities of love may make women believe they can change their partners.” For example, they might never have understood the obvious flaw inthe story of Rapunzel, who remained locked in a high tower until rescued by a knight on a white horse, who broke the door down. “The question,” said Ms Darker Smith, “is why she did not break the door down herself.” 72.The passage is especially intended for _________. A.parents with young daughters B.girls who like reading fairy stories C.girls who think they can change their partners D.parents with grown-up daughters 73.Cinderella, Rapunzel and Beauty in Beauty and the Beast are similar in that _________. A.They all married some princes B.They all changed their partners with love C.They were all abused by their partners D.They all put up with abuse 74.Which of the following statements is true of the women in a control group? A.They don’t believe in fairy tales. B.Th ey don’t believe in the transformational qualities of love. C.They have also experienced abuse. D.They survived abuse. 75.What does the underlined word “submissive”in the 3rd paragraph probably mean? A.kind-hearted B.passive C.gentle D.easy-going Section C (5%) Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.76. It's something that most of us find annoying. We're on our way home after a hard day at school and trying to have a quiet chat with a classmate or get in a little reading, when our peace is disturbed by someone screaming into their cell phone: "I'M ON THE BUS !" 77. A survey published last week suggests Americans do not like the impolite use of today's electronic communication gadgets. Besides noisy phone users, sending andreceiving e-mails while in company are also as very poor manners, reports . 78. One of the practices that participants in the survey most objected to was the use of phones, iPods and other devices during religious festivals. Some 90 per cent of those surveyed thought this was insensitive and disrespectful. 79. The website quotes Dr Genevieve Bell, conductor of the survey and director of Intel's User Experience Group as saying: "Theses are issues about common sense." But she believes that the rights and wrongs of the public use of technology are still in the process of formation. 80. The survey does suggest, according to MSNBC, that most Amencans accepted that the technologies are a fact of modern life. They had nothing against the use of laptops and cell phones in bathrooms. And an electronic thank-you note was just as acceptable as a handwritten one. Section D (8%) Directions: Read the passage carefully and answer the questions or complete the statements in the fewest possible words. Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of a lift operator or the uniform of a five-star general. Why are uniforms so popular in the United States? Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears a uniform tends to inspire more trust than one who appears in civilian clothes, Faith in the skill of a garage mechanic is increased by a uniform . What easier way is there for a nurse, a policeman, a barber, or a waiter to lost professional identity than to step out of uniform? Uniforms also have many practical benefits. They save on other clothes, They save on laundry bills. Theyare tax - deductible. They are often more comfortable and more durable than civilian clothes. Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least. Uniforms also give rise to some practical problems. Though they are long - lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes. 81.What surprises us is that . 82.What are people likely to think of a man in uniform? 83.Why are some people against uniforms? 84.The underlined sentence tells us that .第Ⅱ卷(共45分)I. Translation (20%) Directions: Translate the following sentences into English, using the word or phrase given in the brackets. 1.通常来说,锻炼有益健康。

上海南汇中学2010届高三10月月考语文试题及答案

上海南汇中学2010学年度高三第一学期10月考语文试题(满分150分,考试时间150分钟)一、阅读80分(一)阅读下文,完成第1-6题。

(17分)①绝大部分史学著作皆有序,而多数是自序。

中国传统史学的奠基人司马迁的《太史公自序》,跟《史记》交相辉映,传颂千古。

自古以来,那些蜚声史林的史学家们,没有一个在为自己的著作写序时是率尔操觚,信笔涂鸦的;恰恰相反,无不运笔千钧,力争掷地有声。

②序的长短,并不是判断是否属于上乘之作的标尺。

顾炎武的皇皇巨著《日知录》,自序只有1 97个字,但不仅告诉了读者刊刻是书的原因,更透露其内心世界,谓:“若其所欲明学术,正人心,拔乱世以兴太平之事,则有不尽于是刻者,须绝笔之后,藏之名山,以待抚世宰物者之求。

”这是理解顾炎武及(《日知录》的一把钥匙。

有的史学著作的自序,长逾万言,但言之有物,汪洋恣肆,我们读来爱不释手,不觉其长。

如已故史学家顾颉刚先生的《古史辨》序,从4岁时由保姆抱着他在苏州街上认商店招牌上的字写起,数十年间的经历,史学界的风云,随着笔底惊涛,一泻千里。

又如著名史学冢谭其骧先生的《长水集》序,读来不仅使我们对谭先生的活学历程.严遵的学风,留下难忘的印象,而且,作为当代历史地理学的宗师,他的学术生涯,差不多从一含侧面,浓缩了这门学科的发展史。

③有些史学著作的序,是别人写的,且多为名人。

绝大部分史家为他人作序,都是严肃认真的,仔细阅读书稿,郑重下笔。

7 0年前,学术大师梁启超为蒋方震《欧洲文艺复兴时代史》作序,觉得‘‘泛泛为一序,无以益其善美,计不如取吾史中类似之时代相印证焉,庶可以较彼之短长而自淬厉也。

”如此负责,是多么可贵!结果竞“下笔不能自休”,写了近6万字,只好单独出版,这就是传世之作《清代学术概论》的由来。

最近任继愈先生为《中国行业神崇拜》作序,虽属千字文,但要言不烦,指出此书的学术价值及特点所在,无一字溢美,充分体现了求实精神。

④优秀的序文,常常以其强烈的时代气息,或潺潺流水般的文笔,深深打动读者的心。
