The first thing the lion thinks about is, “I must be able to catch the s__________ antelope, or I will die of hunger.” So, almost at the same time, the an telope and the lion get up and start running toward the rising sun.This is life: full of chances and challenge (挑战). Whether you are an antelope or a lion, you must go a_________ when the sun rises. For students, it is just the same.

In competitions, there are always w_________ and losers. As I grew up, I got to know competition well. In one’s life, there must be competitions, so people can improve.Each time I saw children playing games and heard their laughter, I wished I were that age again.

One day, I was taking part in an English-speaking competition. When I went to the stage, I saw other students looking at me kindly. I s__________ knew what competition was.

Then one day, after a misunderstanding (误解), Joyce stopped talking to Jessica. For more than three months, Joyce refused to talk to Jessica or answer her notes. “During that time, I found out what a important friend she was,” Jessica says, “I couldn’t even give all my attention to my study, I just thought about how to heal (修复) our friendship. ”The next term, Jessica tried again. This time, Joyce was also happy to work it out. It took some time and hard work,but the friendship was healed.Most of us have suffered the pain of broken friendship. But the good news is that most friendships can be healed. Oxford professor Michael Argyle recently finished a 15-year study that found out what makes people happy. What did he find? The key to happiness is having one close relationship and a network of friends. Other studies show that our social connections make us healthier. Keeping healthy friendship is worth the hard work!If there’s broken friendship you’d like to heal, try the following advice:·Try to see things from your friend’s point of view.·Talk about the problem openly and kindly.At first, Jessica didn’t understand why Joyce stopped talking to her. Then Joyce finally explained that Jessica’s trick make her upset. “I finally found out she was angry because I made fun of her in front of the boys in our class.” Jessica explained. Jessica meant nothing by her trick and thought it shou ldn’t make Joyce upset. But when she realized that it was embarrassing(令人难堪的) to Joyce, she stopped. Then their friendship could heal.It’s not strange for friendships to change. Problems come when one friend tries to keep on while the other friend lets go. If your friend isn’t ready to work things out, accept it and move on.93.

Before that, most kids were taught what they needed to learn at home.When you learn reading, math, and other subjects taught in school from your parents or private teachers who come to your house, it's called homeschooling. A kid may be the only one, or he or she may be taught with brothers, sisters, or kids from the neighborhood.Parents choose to home school their children for many different reasons. Sometimes a kid is sick and can't go to regular school. But more often, kids are homeschooled because their parents feel they can give their child a better education than the local school can.You might wonder if kids have to go to school. It's true that kids must be educated, but the law allows the kids to be schooled at home. In fact, more than 1.3 million students do it in the USA alone. These kids can learn just as much as they do in regular schools, but their parents are in charge of their education.Homeschool parents must make sure that their kids get the instruction and the experiences they need. The parents also may have to write a report every year to explain to the government who's teaching the kid and which subjects are being taught at home.(24. 1635 25. math 26. sick 27. local 28. 1.3 29. law 30. report )Part 2II. 31.

I have too much schoolwork to do." When his father heard this. he said, "I promise to give you anything you want if you can finish one year's work." Tom thought for a moment and agreed.On the first Saturday, the boy got up early and worked hard until evening, just like any other farmer. Time passed quickly. Tom's crops grew well. On the last day of the year, the father called his son to him, "I'm happy to see that you have worked very hard this year," said the father. "Now, tell me what you want.”The boy smiled and showed his father a big piece of bread. He made it from the wheat he worked so hard to grow. "I've already got the best thing. No pain, no gain.

Listen to the passage and complete the following sentences 4These days, most people in Britain and the US do not dress formally. But sometimes it is important to wear the right things.Many British people don't think about clothes very much. They just like to be comfortable. When they go out to enjoy themselves, they can wear almost anything. At theatres, cinemas, and concerts you can put on what you like from beautiful suits and dresses to jeans and sweaters. Anything goes, as long as you look clean and tidy.But in Britain, as Well as in the US, men in offices usually wear suits and ties, and women wear dresses or skirts(not trousers). Doctors, lawyers, and business people wear formal clothes. And in some hotels and restaurants men have to wear ties and women wear tidy dresses.In many ways, Americans are less formal than British people, but they are careful with their clothes. At home, or on holidays, most Americans wear informal or sports clothes. But when they go out in the evening, they like to look nice. In hotels and restaurants, men have to wear jackets and ties, and women wear pretty clothes.It is difficult to say exactly what people wear in Britain and the US, because everyone is different. If you are not sure what to wear, watch what other people do and then dress the same.

With thick stonewalls and high towers, castles were noisy places with an unpleasant smell. Horses, cows, chickens and sheep walked free. Soldiers practiced sword fights every day. And children of all ages played around them. Castles did not have central heating; the only heat came from the fireplace. Even in summer the castle was cool. People living in the castle had to use blankets to keep warm while at work.Life during the Middle Ages began at sunrise. Servants lit the fire, swept the floor and cooked the morning meal. After dinner, everyone continued his or her work. the owners of the castle sometimes took his guests hunting or shooting. His wife spent much of the day watching the servants work, as well as cooks working in the kitchen. Supper was simple and eaten late, just before bedtime.You may find some old magic books in a castle as Harry Potter once did.

Then she put his stick beside the table."Thank you, miss," he said, kindly."You' re welcome, sir," she said.After he had finished his breakfast, the waitress brought him the change from his bill. He left it on the table. She helped him up and walked with him to the front door.When she went to clean his table, she found a business card under his plate and a note on a napkin.

It was really different from my school in China. Girls wore grey skirts and white shirts, boys wore grey trousers, and everyone wore the school tie. Some of Sam's lessons Were a bit strange for me. We were reading Shakespeare in the English lesson, and there were various old-fashioned words like "thou" and "thee" to mean "you". In history lessons, we studied 20th Century China. It was strange hearing English people trying to say all our Chinese names! Classes were also a lot more relaxing and active than in China. Male teachers were called "sir" and female teachers "miss" out of respect, but everyone shouted out and waved their hands in lessons. It was more like a debate than a class. A bell rang at the end of each lesson and everyone jumped up to go to the next class. At break we bought "potato crisps" and "cakes" in the dining room. Lunch was later than in China-at one o' clock. We had big plates of pies wi.th peas and carrots. For dessert there was hot sweet rice, called rice pudding, with jam in it. It was good that I'd had a huge lunch because at Sam's school, Monday afternoons are taken up with sports.Part 1I. A. 1. D 2. E 3. B 4. G 5. A 6. CB. 7. A 8. C 9. B 10. A 11. D 12. B 13. D 14. C 15.

（16分）???????????????????????????????? ?卖桔者言?张五常①作为一个研究价格理论的人，我对实证工作好之成癖。

要了解玉石市场的运作，我曾在广东卖玉。

在美国研究原油价格时，我曾到油田及炼油厂调查了好几个月。

理论若经不起实证的考验，是很难站得住的。

一个有实据在手的后起之秀，有时只要用三招两式，就可把一个纯理论的高手杀得片甲不留。

②香港年宵市场在年宵（除夕）的那一晚，需求的变动极快极大。

变动的方向大致上大家都预先知道。

1000块钱一枝的桃花可在几个钟头之间变得一文不值。

若不是买卖双方在期待上有了错误，上好的桃花哪会有弃于街头的明显浪费？同样一枝花，有人用200元买也有人用50元买，如何理解？年宵货品不断变动的价格是怎样决定的？买卖双方期待上的错误是怎样产生的？这些问题既困难又重要。

③要在这些问题上多一点了解，我决定在年宵的那一晚亲自卖桔。

这算是我第二次的经验。

第一次是一年前的年宵。

那次连天大雨，年宵当晚更是倾盆而下。

摆了数天的桔子十之八九都因雨水过多而掉了下来。

我知道大势已去，无心恋战，数十元一盆成本的四季桔，以5元清盘了事，蚀了数千元。

④今年卷土重来，也是意不在酒。

入货200多盆，每盆成本40元。

送了一小部分给亲友，余下大约二百盆就在年宵晚上8时起，在一个行人众多的空地盘出售。

我和三个朋友一起出售的是四季桔，邻近地盘少有卖桔的人，所以到凌晨三时半便将桔子全部卖出。

全部卖出并不一定有钱赚，赚钱与否是要看每盆桔子平均售价的高低。

在我们一定要全部卖出的局限下，入货的多少，价格转变的快慢，价格高低的分布，讨价还价的手法，都有很大的决定性。

我们200盆的平均售价大约是每盆55元（最高80元，最低20元）。

我们所赚得的就是那些送给亲友的桔子。

而我自己从卖桔所领悟到的经济含义，却是大有所值！⑤9时左右，客似云来。

He decided to choose the players who were the most aggressive and played the hardest.Brooks was pleased with his final choices. However, he knew his team would be the underdog if they faced the powerful team of professionals from the Soviet Union(USSR). During the week before the Olympics began, the U.S. team played the Soviets in an exhibition game and last badly, 10-3. In spite of the defeat, Brooks thought that if his team played up to their potential, they might be able to win a medal.After the 1980 Winter Olympic Games began in Lake Placid, New Y ork, the United States was behind Sweden 2-1 in their first game. With a last-second shot, Bill Baker tied(与……打成平局) the game for the U.S. team.In the second round, the United States defeated Czechoslovakia 7-3.

Then, in the last second of the first period, the Americans tied the score. With 10 minutes left in the game, the Americans took the lead and held on for a slim 4-3 victory. Many sports fans consider this victory to be one of the greatest upsets in the history of sports.

To introduce Nanyang Environment & Water Research Institute.(C)The coast of the State of Maine is one of the most irregular in the world. A straight line running from the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you followed the coastline between these points, you would travel more than ten times as far. This irregularity is the result of what is called a drowned coastline. The term comes from the glacial（冰川的）activity of the Ice Age. At that time, the whole area that is now Maine was part of a mountain range that towered above the sea. As the glacier descended, however, it applied enormous force on those mountains, and they sank into the sea.As the mountains sank, ocean water charged over the lowest parts of the remaining land. And the highest parts of the former mountain range, nearest the shore, remained as islands. Marine fossils found here are 225 feet above sea level indicating the level of the shoreline prior to the glacier.The 2,500-mile-long rocky and jagged coastline of Maine keeps watch over nearly 2,000 islands. Many of these islands are tiny and uninhabited, but many are home to blooming communities. Mt. Desert Island is one of the largest, most beautiful of the Maine coast islands left behind by the glacier. Measuring 16 miles by 12 miles, Mt. Desert was very nearly formed as two distinct islands. It is split almost in half by Somes Sound, a very deep and very narrow stretch of water seven miles long.For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, has afforded summer homes for the wealthy. Recently, though, Bar Harbor has become a new arts community as well. But the best part of the island is the unspoiled forest land known as Acadia National Park. Since the island sits on the border between two different geographical zones, the park supports the plants and animals of both zones. It also lies in a major bird migration lane and is a resting spot for many birds.The establishment of Acadia National park in 1916 means that this natural monument will be preserved and that it will be available to all people, not just the wealthy. V isitors to Acadia mayreceive nature instruction from the park naturalists as well as enjoy camping, hiking, cycling, and boating. Or they may choose to spend time at the museum learning about the Stone Age inhabitants of the island.72．The large number of small islands along the coast of Maine is the result of __________.A. the drowning of the Maine coastlineB. glac ier‘s forcing mountains into the seaC. the irregularity of the Maine coastlineD. ocean water‘s flooding the mountain range73．From the passage, we learn that __________.A. the coastline of Maine is ten times longer after the Ice AgeB. there are more than 2500 islands along the Maine coastlineC. Mt. Desert Island has been broken apart by a 7-mile-long water stretchD. an arts community gave way to the summer homes on Mt. Desert Island74．What CANNOT be inferred about the Acadia Nation Park?A. It welcomes all the people, rich or poor.B. It has much appeal for bird-watching lovers.C. It offers visitors both entertainment and education.D. It is a border between the two geographical zones.75．Which of the following might be the best title of the passage?A. The past and the present of MaineB. The formation of Maine coastlineC. Efforts for preserving national parksD. Tourist attractions on Mt. Desert IslandSection CDirections: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.It‘s been said that ―everybody lies sometimes.‖ And it‘s true. Everyone does lie from time to time. Men lie; women lie. Husbands lie, friends lie, wives lie, and believe it or not, your mother might lie.A recent study showed that 91% of all people lie on a regular basis, and people tell at least 13 major lies a week.77.The first thing one has to understand about lying is that there are at least five different types of liars: the model of absolute integrity, the real straight-shooter, the pragmatic fibber, a real Pinocchio andthe compulsive liar, according to sociologist – anthropologist Dr. Gina Graham Scott.78.

Newby , the professor of sociology at Central Michigan University, believes that men are more likely to tell lies than women . ―Men are more concerned about how they present themselves in public, the impression they make on people and things like that,‖ he says. ―Men are always trying to impress people in the work and want to make sure that their presentation of self is one that makes them look good.‖ Women, on the other hand, Dr. Newby believes , are more private people and their relationship tends to be more interpersonal, as opposed to having to put on a public face. Wom en are more vulnerable and they are not as likely to try to pull the wool over someone‘s eyes like men.79. Dr Ronn Elmore, Los Angeles-based relationship counselor, does not believe that lying is based on gender. ―But I believe when women lie it tends to be verbal, plain old-fashioned lies with words. But when men lie, it is often nonverbal, as in doing what he says he would not do or not doing what he promised he would do. Either way , it‘s a lie, male version or female version. It is the opposite of i ntegrity.‖80. V esta Callender, psychotherapist in New Y ork City, also agrees that one‘s gender does not play a role in lying, but men and women do lie differently. ―Women concern more while lying. They plan better,‖ Callender notes. ―They create a hist ory around the lie, and they try to project into the future what might happen if the lie is detected. With a woman, a lie has a beginning, a middle and an end. It‘s a real entanglement.‖ Callender believes that men ―tend to lie for the moment or to get out of a situation. Men think less about how the lie can be detected.‖Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.All of us communicate with one another non-verbally, as well as with words. We gesture with eyebrows or a hand, meet someone else‘s eyes and look away, shift positions in a chair. These actions we assume are random and incidental. But researchers have discovered in recent years that there is a system to them almost as consistent and comprehensive as language.Every culture has its own body language, and children absorb its difference along with spokenlanguage. A Frenchman talks and moves in French. The way an Englishman crosses his legs is nothing like the way a male American does it. In talking, with a future-tense verb, Americans often gesture with a forward movement.There are regional idioms too. An expert can sometimes pick out a native of Wisconsin just by the way he uses his eyebrows during conversation. Y our sex, moral background, social class and personal style all influence your body language.Usually, the wordless communication acts to qualify the words. What the non-verbal elements express very often, and very efficiently, is the emotional side of the message. When a person feels liked or disliked, often it‘s a case of ―not what he said but the way he said it.‖ Psychologist Albert Mehrabian has come up with this formula: total impact of a message = 7% verbal + 38% gestural + 55% facial.Experts in kinesics – the study of communication through body movement – are not prepared to spell out a vocabulary or gestures. When an American rubs his nose, it may mean he is disagreeing with someone or rejecting something. But there are other possible interpretations, too. Another example: When a student in conversation with a professor holds the older man‘s eyes a little longer than is usual, it can be a sign of respect and affection; it can be a challenge to the professor‘s authority; or it can be something else entirely. The experts look for patterns in the context, not for an isolated meaningful gesture.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)81．What idea does the author aim to convey in paragraph 2?82．Besides moral background, __________ are the other three factors affecting people‘s body language.83．F rom Albert‘s formula, we learn that the body language __________.84．What can you conclude from the examples given in paragraph 5?第II卷I.

Here are three examples from the minds of China's young inventors.Foot Controlled MouseThis new kind of mouse is controlled by the feet instead of the hands, to help disabled people when surfing the Internet.The new invention is called a "surf mouse", and looks like a pair of blueslippers. When users press the slippers with their forefeet, they are clickingthe left mouse button; when people press with their heels, they are clicking the right mouse; when they roll their feet over the slippers, they can surf Web pages.Dirty Water FilterThe "pump of life", a filter, can make dirty water drinkable. The pump is over 30 centimeters long. It has an in-pipe at the top and out-pipe at the end. There are two main parts: the drive zone to pump water and the material zone to eliminate harmful things. Rain fish tank water and coalmine water can all be cleaned in the material zone. The invention could be used for many kinds of disaster relief. The inventor of the filter told us that water was delivered by helicopters to Wenchuan in 2008. If the water-purifying equipment had been sent instead, people could have had more water faster after the earthquake.Transformer VehicleThe multi-functional vehicle is named Tranfus. By changing thebreadth (宽度) of tires and the structure of a car, it can become a motorbikeor a luggage carrier. The name Tranfus is a short form of “transforming forus".Traffic jams can make a driver go crazy. The Tranfus can change into a luggage carrier,and users could walk with it. When started, the roof transforms, turning into a motorbike. But its inventor doesn't think Tranfus will be on the market soon as some auto companies like it, but none are willing to invest.（）74.

Read the passage and fill in the blanks with prop er words （在短文的空格内填入适当的词，使其内容通顺，每空格限填一词，首字母已给）：（共14分） Accordingto experts, the word Hutong originated from Mongolian languagemeaning "Well (井) . In ancient times, people-tended to gather and live aroundwells. So the original meaning of Hutong should be a place where people gather andlive. But Hutong first a 86 in Beijing during the Y uan Dynasty .The old city was completely destroyed during the war. So they had to rebuild it.First, they had to find a center, and then built a r 87 square city. At that time, there was a clear definition for "A venue, Street and Hutong". A 37-meter-wide road was called an avenue, an 18-meter-wide one was called a street, and a 9-meter-wide lane was called a Hutong.Most of today's Hutongs were formed during the Ming and Qing Dynasties. Nobody knows e 88 how many Hutongs there are in nowadays Beijing. But if we connected all the Hutongs together, their total l 89 would even be longer than the famous Great Wall, which is about 4,000 miles.Today you can find v 90 Hutongs with different shapes, sizes or directions. The shortest one is only 40 centimeters wide. And some Hutongs have more than 20 turns.As we walk t 91 the Hutongs, you may find most of them look almost the same wi th gray-colored-walls and bricks. Actually inside those walls are the courtyard houses, where people live. In Chinese we call them “Siheyuan". "Si" literally means four; "he" means to surround and "yuan" refers to the courtyard. So a rectangular wall enclosing four houses, one built on each side facing intothe center, is called a Siheyuan. When they were first built, usually one Siheyuan was o 92 by only one family. And nowadays, with the growth of the population, most Siheyuans are shared by 4 to 10 families.86. ________________ 87.________________ 88.________________ 89.________________90. ________________ 91.________________ 92.________________D. Answer the questions（根据短文内容回答下列问题）:（共12分）Boys do best with "as few girls as possible" in English lessons at primary and secondary school, Steven, a research student at Bristol University, told the RoyalEconomic Society's conference. But when it comes to math and science, both boys andgirls at primary schools achieve up to tenth of a grade more when there is a highproportion (比例) of girls in the class, Steven found.Steven studied boys' and girls' test results at the ages of 7, 11, 14 and 16 in 16,000 schools in England between 2002 and 2004 for his Ph.D. He analyzed the test scores to see whether the proportion of girls in a year group make a difference to the results of both genders (性别) in math, science and English.Boys often get to a tenth of a grade worse when they study English with high numbers of girls as opposed to few or no girls, Steven found. The more girls there are in an English class, the worse boys perform. This is particularly the case in primary schools, he discovered.Steven's results show boys should be taught English in single-sex classes. Girls, who outperform boys in English at every stage at school, are unaffected by the number of boys in their English classes. He said, "The results say that boys would benefit at all ages from being taught English with as small a proportion of girls as possible. In math and science, lie results tend to show that both boys and girls benefit from having more girls in the c lassroom. A mix of the genders in both science and math is the best."Steven said boys may do worse in English when there is a high proportion of girls in their class because they realized that the girls are better than them. It could also be that teachers use teaching styles more appropriate to girls when there are more girls than boys in the class. Both genders perform better in math and science at primary school when there are more girls in the class because boys tend to break the class rules.93. Will boys do better in English if there are few girls in their class?94. Which age groups did Steven study boys' and girls' test results?95. What did Steven suggest teaching English to boys at school?96. What is the best classroom teaching style in math and science?97. Why do boys do worse in English when there are more girls in class?98. Do you agree that girls can always do better in study? Why or Why not?IX. Writing (作文): (共20分)99.
