A

The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety. That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.

Parbati Barua's father was a hunter of tigers and an elephant tamer驯养人. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.

Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old fife. "Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase," she says.

But Parbati doesn't catch elephants just for fun. "My work," she says, "is to rescue man from the elephants, and to keep the elephants safe from man." And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to

guide the animals back to the jungle before they can kill.

The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. "Eventually they grow to love their tamers and never forget them. They are also more loyal than humans," she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!

56. For Parbati, catching elephants is mainly to .

A. get long lasting excitement

B. keep both man and elephants safe

C. send them back to the jungle

D. make the angry elephants tame

57. Before Parbati studied in a boarding school, .

A. she spent her time hunting with her father

B. she learned how to sing love songs

C. she had already been called an elephant princess

D. she was taught how to hunt tigers

58. Indian elephants are getting increasingly angry and they revenge because __________.

A. they are caught and sent for heavy work

B. illegal hunters capture them and kill them

C. they are attacked and their land gets limited

D. dogs often bark at them and chase them

59. The passage starts with an elephant story in order to explain that in India _________.

A. people easily fall victim to elephants' attacks

B. the man-elephant relationship is getting worse

C. elephant tamers are in short supply

D. dogs are as powerful as elephants

B

Why play games? Be cause they are fun, and a 1ot more besides. Following the rules…planning your next move...acting as a team member…these are all “game” ideas that you will come across throughout your life.

Think about some off the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .

Many children’s games have a practical side Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones. Which sharpens the hand-eye coordination(协调)needed in hunting.

Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.

Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.

Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.

60. Through playing hide-and-seek, children are expected to learn to ________.

A. be a team leader

61. The underlined part in Paragraph 2 most probably means that games can________.

D. change people’s views of sporting events

62. According to the passage, why is winning Olympic medals so encouraging?

A. It inspires people’s deep love for the country.

B. It proves the exceptional skills of the winners.

C. It helps the country out of natural disasters.

D. It earns the winners fame and fortune.

63. Iribarne’s goal of forming the foundation is to _______.

C.People are advised to play games for fun. D.Sports increase a country’s competitiveness.

C

When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come

from, so it seems cruel not to give some money to beggars.

Certainly, most of th e world’s great religions order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer practiced by all the people. Quite a few people will not give to beggars. Let us look at their arguments.

Firstly, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil (恶行). Secondly, there is the worry that the money you give will be spent on beer, wine or drugs. Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is not the reason for losing one’s sense of pride and self-dependence.

Related to this is the opinion that the problem should be dealt with by the government rather than by ordinary people. Some people think beggars should go to the local government department and receive help.

It is hard to come to any final conclusion; there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver.

65. What is mainly discussed in the passage?

A. Moral deeds of most people.

B. Religious activities in the society.

C. Moral goodness of the giver.

D. Arguments on giving to beggars.

66. What can we infer from the sentence “But has the world changed?” in the second paragraph?

A. People no longer know who suffers misfortune in the village.

B. There some people not willing to do what was morally right before.

C. We don’t meet with those who need others’ help any more.

D. Now it is the government that has the duty to help the beggars.

67. Which of the following is NOT mentioned in the passage?

A. Some people dress up to pretend to be beggars.

B. Some beggars want money for their schooling.

C. Some beggars use the money to buy drugs.

D. Some beggars have no excuse for begging.

68. In the last paragraph, the writer thinks it hard to reach any final conclusion, because .

A. the cases can be so different

B. there are so many beggars

C. there is so much money wasted

D. there are so many different arguments

D

“Image is everything.”An entire industry has been built upon the assumption(设想) that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance(事实) behind the image, the product, service or person will fail eventually.

First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies. But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back. For example, the Arthur Andersen accounting firm(会计事务所)had spent decades building up an image of trustworthiness(可

信赖). But the recent scandal (丑闻) showed that behind that image, it cheated in business practices. Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit. Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm. Similarly, personal advisers can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.

To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling”of a person. But image is only half of the equation(等式方程式). What lies behind that image is every bit as important as the image itself ——the person or product must deliver on(履行)that image or there is little chance for long-term success.

69. The downfall of the Arthour Andersen accounting firm is due to ________.

A. its dishonesty in business

B. its previous images

C. its bad management

D. its poor service

70. Why did some famous people fall from grace?

A. Their images were not well built up

B. They failed to live up to their images.

C. They felt much pressure from the public

D. They paid little attention to fame and fortune.

71. The structure of the passage is ________.

A: Argument P: Point C: Conclusion

72. The author tries to argue that _________.

A. image creates everything

B. image is the key to success

C. truth is unlikely ever to be equalled

D. truth and image are equally important

E

How words came into being is unknown. All we assume(推测)is that some early men invented certain sounds, in one way or another, to express thoughts and feelings, actions and things, so that they could talk with each other. Later they agreed upon certain signs, called letters, which could be put together to show those sounds, and which could be written down. Those sounds, whether spoken or written in letters, are called words.

The power of words, then, lies in their associations - the things they bring up to our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words bring back to us the happy and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.

Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings. This clever use of words is what we call literary style(文体). Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and which by their position and association can move men to tears, We should therefore learn to choose our words carefully and use them correctly, or they will make

our speech silly and common.

73. We learn from the text that language might have begun with

A. expressions

B. actions

C. signs

D. sounds

74.What is mainly discussed in Paragraph 2?

A. The learning of new words.

B. The importance of old words

C. The relation of human experience with words.

D. The gradual change and development of words.

75. In the last paragraph, what does the author suggest that we should do?

A. Use words skillfully.

B. Make musical speeches

C. Learn poems by heart.

D. Associate with listeners.

The United States is facing a growing concern: rising obesity(肥胖) rates. A new report says adult obesity rates rose last year in 23 of the 50 states. And, the percentage of obese(过胖的)children was at or above 30% in 30 states. Mississippi had the highest rate of adult obesity in the new study.

32.5% of the state’s adults were obese. Mississippi also had the highest rate of obese and overweight children. 44.4% of all children between the ages of ten and seventeen years were obese or overweight.

The study used a system of measurement called the Body Mass Index(B-M-I) to define words like obese and overweight. To find your B-M-I, divide your weight in kilograms by height in meters squared. A normal B-M-I is between 18.5 and 24.9. The B-M-I of someone overweight is between 25 and 29.5. And, an obese person has a B-M-I above 30.

The new report says widespread obesity is increasing the rates of long-lasting diseases, such as heart disease. Obesity is also responsible for an increasing part of health care costs in the United States. Health care costs have grown while many Americans are getting fatter. A lack of physical exercise, watching TV too much and eating junk food contribute to the rising obesity rate. The report says the current economic recession(经济衰退) could worsen obesity rates by increasing food prices. This would make healthy foods cost more. The report blames the recession for rising rates of depression, anxiety and stress, which are closely linked to obesity in many cases.

The report offers some ideas for dealing with obesity within government health care reforms. They include making sure that every adult and child has a right to preventive medical services. Also, people should do more physical exercise, drive less and eat less junk food to fight obesity. Widespread obesity in the US

The rapid increase of private cars in recent years has caused some social problems. Some big cities are considering whether to control the number of cars. Different people have different ideas about it.

Some people think it necessary to do so. For one thing, the roads are so crowded that traffic jams can be seen everywhere. For another, there're not enough parking areas available for cars. Besides, by controlling ears, we can reduce air pollution around us. They suggest cities improve public

transportation and people be encouraged to ride bicycles.

However, some people think it unreasonable. They hold the opinion that the increase of private cars will promote the car industry, which contributes greatly to the development of the country's economy. Moreover, cars bring convenience to people and save them a lot of time. They suggest cities improve the management of traffic and raise the cost of using cars.

In my opinion, we should take measures to solve the problem. Laws should be passed to regulate the traffic. And cities should build more subways so that people can have a better choice for travel.

2013届高三语文模拟试卷及参考答案安徽省六安一中2013届高三年级第一次月考 语文

六安一中2013届高三年级第一次月考 语文试卷 时间:150分钟分值:150分 第I卷阅读题(共66分) 一、论述类文本阅读(9分) 阅读下面的文字,完成1~3题。 舜文化 ①《尚书》云:?德自舜明。?《史记》载:?天下明德皆自虞帝(虞舜)始。?舜帝是?德?的化身,简言之,舜文化就是舜帝身体力行所创造的道德文化,它是一种原生性的道德本体文化。因此,舜帝是中国道德文化的鼻祖。 ②舜所处的时代,是中国社会发展的转折时期。在这个时期,东夷集团与华夏集团的融合已经完成,亦即炎、黄民族的融合已经完成,在部落联盟的体制沿袭了数千年后,国家已经初步形成;作为个体的人,也已经进入了由部落联盟——诸侯国组合起来的?古国?大社会。因此,在社会生产之中,需要有一种不同于以往的关系和双方都能接受和遵守的准则,才能维护诸侯国之间和人与人之间的团结与和谐。作为诸侯国联盟首领的舜,正是适应了这一社会发展的需要,身体力行地创造、想方设法地推行了这些准则,并使整个社会都遵守这个?道德?规范,成为人类由文明产生阶段进入文明发展阶段的重要标志。 ③文化的发展具有历史的继承性。我们说孔子是儒文化的创始人,然而,孔子的功绩在于集文化之大成;儒家文化实际上只是孔子对舜文化的继承和弘扬;纵使是儒文化的核心内容之?仁?,也只是孔子在总结商周文化基础之上的画龙点睛。儒学三重道德——人伦道德、社会道德、宇宙道德的源头来自于舜帝的道德文化。楚简中的《唐虞之道》写道:?爱亲忘贤,仁而未义也;尊贤遗亲,义而未仁也……爱亲尊贤,虞舜其人也。?由此可以证实,儒家三重道德的基本构架就是发轫于舜帝所创建的道德文化。 ④各民族的文化都以本民族的特有形式发展起来,形成本民族的传统。舜文化产生在炎、黄民族融合之后,所以,它代表的是炎黄子孙的共同利益,这也是舜文化得以继承和不断弘扬的原因。舜帝虽然居?三皇五帝?之末,但是,舜帝开创了?德治?文明的崭新时代,具有里程碑的作用和历史意义。 ⑤以农耕文化为内涵的炎帝文化,以政体文化为内涵的黄帝文化,以道德文化为内涵的舜帝文化,这是中华文化的三块里程碑。农耕文化、政体文化、道德文化是中华远古文化的源头。又特别以舜文化为博大精深,它涵盖了社会、自然两大学科,其内容包括了政治、经济、军事、教育、文艺、民族关系等各个领域。舜文化是以儒家文化为核心的中华民族传统道德文化的源头。唐代著名思想家韩愈在他的《原道》一文中梳理儒家的传授关系时说,是?舜以是传之禹,禹以是传之汤。汤以是传之文武周公,文武周公以是传之孔子,孔子传之孟轲?。孔孟传之于后人。 ⑥中华传统文化之根脉是舜文化。舜文化是儒家道德价值之根脉。从这个意义上说,没有

宁夏银川一中2015届高三上学期第一次月考 高三 2013-09-08 19:17 宁夏银川一中2015届高三上学期第一次月考 语文试题 第I卷阅读题 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l~3题。 夏商周三朝,被中国传统史学家称为“三代时期”。商人性格活泼,注重感官享受,殷墟妇好墓挖掘出的210件礼器中,仅酒器就有方彝、尊、献、壶,爵等15种175件,占全部礼器74%,酒器在墓葬中的批量摆置反映了商人重酒的风气。 《诗?商颂?烈祖》中强调祭祖时美酒的重要性“既载清酤,赉我思成”。张光直在《商代的巫与巫术》中提出:“酒是一方面供祖先神祇享用,一方面也可能是供巫师饮用以达到通神的精神状态。”可见早期的祭祀离不开酒,而祭祀时候的饮酒也有特别的规定,一般先由巫师或祭司饮酒,传达神灵的旨意。 上世纪80年代出土的平民墓葬中,有随葬品的均为爵、觚等酒器。商代酒器最简单的组合是一爵一觚。现代考古学家认为,这种酒器之所以命名为“爵”,是由于它的造型像一只雀鸟,前面有流,好像雀啄,后面有尾,腹下还有细长的足,而古代爵与雀同音通用。宾主酒酣耳热之时,乐舞表演将把宴会的气氛推向高潮。根据《商颂》中的描述,重要的祭礼都以舞队的“万舞”开始,伴随着鼓、管、钟、磬等乐器的伴奏,最后在盛大的宴飨中结束。被总称为“万舞”的舞蹈包括舞者手持马辔的武舞,以及脚踩双杆,类似高跷的林舞。 与商代不同,周代的酒成为了王室弘扬“礼制”与仪典的载体,饮酒聚宴往往只是繁琐而庄重的祭祀典礼结束后的附属程序。对于饮宴具体制度,《礼记》记载了很多严格要求,比如参与祭祀宴会者的身份不同,其使用的酒器也有所差异:“宗庙之祭,贵者献以爵,贱者献以散;尊者举觯,卑者举角。”祭祀之时,酒之种类不同,摆放位置也有严格繁琐的规定,比如明确要求祭典时,淡薄的酒放置于内室,甜酒在门边,浅红色的清酒在堂上,清酒在堂下。周平王东迁洛邑后,周王室对诸侯国的控制能力一落千丈,随之的春秋战国时
