A

When Lew Alcindor was 13, and obviously still growing, a group of schools began offering him scholarships . The Alcindors decided to send their only child to Power Memorial Academy, a small school on Manha ttan’s West Side.

At Power, Alcindor came under the control of Coach Jack Donohue, a strict young man who already gained his fame as one of the best coaches in the city. Donohue brought Alcindor along slowly. As a first-year student, the boy was not able to do much but wave his long skinny arms and shoot a basket now and then. But by the second year, when he was 15 years old and nearly 7 feet tall, Alcindor was quick and skillful enough to make the high school All-American team and to lead Power to an undefeated season.

From then on he simply got better. Some rival coaches used to take their teams quickly away from the floor before Power warmed up so that their players would not see him any sooner than they had to. Wearing size 16D shoes and sucking a lollipop (棒棒糖), Alcindor would loosen up by starting his leaping lay-ups (跨越式上篮). Then he would casually shoot the ball with either hand, to the delight of the fans.

When reporters and photographers began to follow Alcindor closely, Donohue protected his boy firmly. He simply ordered Lew to talk to no member of the press, and this suited Lew fine. He was not comfortable talking to grown-ups, perhaps because he towered over them. Discouraged photographers began following him in secret as though he were an easily-frightened giraffe. Once after ducking into a subway to escape, Alcindor told a friend that it was all becoming like policemen and robbers. “People want you not for yourself,” Donohue warned him, “but because you’re a basketball player. Don’t forget that. ”

21. Many schools offered Alcindor scholarships because_________.

A. he was young

B. he was hardworking

C. he was tall for his age

D. he was skillful at playing basketball

22. Why did some rival coaches take their teams away from the floor before Power warmed up?

A. Their teams refused to play Power.

B. Their teams feared to see Alcindor.

C. Their teams would lose courage.

D. Their teams would lose interest.

23. What does the last paragraph mainly discuss?

A. How Donohue protected Alcindor from the press

B. How Alcindor disliked meeting reporters

C. Why the press followed Alcindor closely

D. Why the public wanted Alcindor badly

B

Supermarkets are trying out new computers that make shopping carts (购物车)more intelligent. They will help shoppers find cups or toilet soap, and keep a record of the bill.The touch-screen devices are on show at the Food Marketing Institute’s exhibition here this week. "These devices are able to create value and get you around the store quicker," said Michael Alexandor, manager of Springboard Retail Networks Inc., which makes a smart cart computer

called the Concierge.

Canadian stores will test the Concierge in July. A similar device, IBM’s "shopping buddy," has recently been test-marketed at Stop & Shop stores in Massachusetts. Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.

“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexandor. People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.

The devices also keep a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay. The new computerized shopping assistants don’t come. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device. 24. Which of the following is the correct order of shopping with the computerized shopping carts?

a. Start the system.

b. Make a shopping list.

c. Find the things you want.

d. Go to a self-checkout stand.

A. abdc

B. bacd

C. acbd

D. bcad

25. We can learn from the last paragraph that_________.

A. intelligent shopping carts cost a large sum of money

B. the Concierge is cheaper than the Buddy devices

C. shop assistants with computer knowledge are well paid

D. average stores prefer the Concierge to the Buddy devices

26. What might be the most suitable title for the text?

A. New age for supermarkets

B. Concierge and Shopping Buddy

C. New computers make shopping carts smarter

D. Touch-screen devices make shopping enjoyable

C

Treasure hunts(寻宝) have excited people's imagination for hundreds of years both in real life and in books such as Robert Louis Stevenson's Treasure Island. Kit Williams, a modern writer, had the idea of combining the real excitement of a treasure hunt with clues found in a book when he wrote a children's story, Masquerade(化装舞会), in 1979. The book was about a hare, and a month before it came out Williams buried a gold hare in a park in Bedfordshire. The book contained a large number of clues to help readers find the hare, but Williams put in a lot

of red herrings(鲱鱼), or false clues, to mislead them.

Ken Roberts, the man who found the hare, had been looking for it for nearly two years. Although he had been searching in the wrong area most of the time, he found it by logic, not by luck. His success came from the fact that he had gained an important clue at the start. He had realized that the words, "One of Six to Eight" under the first picture in the book connected the hare in some way to Katherine of Aragon, the first of Henry VIII's six wives. Even here, however, Williams had succeeded in misleading him. Ken knew that Katherine of Aragon had died at Kimbolton in Cambridgeshire in 1536 and thought that Williams had buried the hare there. He had been digging there for over a year before a new idea occurred to him. He found out that Kit Williams had spent his childhood near Ampthill, in Bedfordshire, and thought that he must have buried the hare in a place he knew well, but he still could not see the connection with Katherine of Aragon, until one day he came across two stone crosses in Ampthill Park and learnt that they had been built in her honor in 1773.

Even then his search had not come to an end. It was only after he had spent several nights digging around the cross that he decided to write to Kit Williams to find out if he was wasting his time there. Williams encouraged him to continue, and on February 24th, 1982, he found the treasure. It was worth £3000 in the beginning, but the excitement it had caused since its burial made it much more valuable.

27. The underlined word “them”( paragraph 1) refers to ______.

A. red herrings

B. treasure hunts

C. Henry VIII's six wives

D. readers of masquerade

28. The stone crosses in Ampthill were built ______.

A. to tell about what happened in 1773

B. to show respect for Henry VIII's first wife

C. to serve as a road sign in Ampthill Park

D. to inform people where the gold hare was

29. Which of the following describes Roberts logic in searching for the hare?

a. Henry VIII's six wives

b. Katherine's burial place at Kimbolton

c. Williams childhood in Ampthill

d. Katherine of Aragon

e. stone crosses in Ampthill Park

A. a-b-c-e-d

B. d-b-c-e-a

C. a-d-b-c-e

D. b-a-e-c-d

30. What is the subject discussed in the text?

A. An exciting historical event.

B. A modern treasure hunt.

C. The attraction of Masqurrade.

D. The importance of logical thinking.

contributions we had 49 . One of my coworkers, Maggie, made the rounds with me every day from one department to another to pick up the canned goods and other 50 . Maggie was over sixty but pushed our food trolley around with the 51 of a woman half her age.

As we were making our rounds one day,I asked her where she got all the energy and enthusiasm. “Annie,”she said, “with the unemployment rate touching 10 percent, I can’t think of a better way to be 52 for keeping our jobs when so many have 53 theirs. Sure money is 54 . But when isn’t it? People need food.” As I listened to Maggie, the milkman’s words 55 in my ears, “Kids need milk.”

How an unbelievable scene! A modern young couple were eating fruit in public and had thrown a plenty of waste on the ground. When an old cleaner comes to clean up, the man was very angry. He pointed at the cleaner, said in a loud voice," How impolite! They haven't finished eating!" " How could people behave such badly?" I thought. Obvious, in their eyes, they could do all they liked and ignore others’ feelings. In my opinion, we should pay attention our behavior, obey public rules and respect other people’s works.

作文:

Dear Jim,

How is everything going? I am glad to receive your e-mail, in which you asked me about my career plan for the future. Now I am writing to share it with you in details.

I made up my mind to be a journalist when I visited the Xinhua News Agency, the top one in China, last year. I chose it as my career based on the following two reasons. First, it is a job that can get me exposed to new things every day and thus keep me energetic and passionate all the time since I really hate to follow the same routine every day. Second, working as a journalist can help realize my childhood dream of being a

hero by fighting against evil and spreading justice.

To achieve this goal, I plan to apply for the Communication University of China, whose major, Journalism, has been ranked the first for many years in a row across the whole country. After getting my Bachelor Degree of Journalism, I will continue my study in a world-famous university to broaden my horizons to better fit my future post.

That is all about my career plan. What do you think of it? I am looking forward to hearing yours if you have got one.

Yours,

Li Hua

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
