Justin’s bedroom was so full of flat bicycle tires, bent tennis rackets, deflated（瘪掉的）basketballs, and games with missing pieces that you could barely get in the door. His parents pleaded with him to clean out his room.
“What use is a fish tank with a hole in the bottom?” his father asked. But Justin simply smiled and repeated his motto, “Never throw anything out, you never know when it might come in handy.”
When Justin was away from home, he always carried his blue backpack--a smaller version of his bedroom--a place to store the many objects that he collected. It was so worn and stretched that it hardly resembled a backpack anymore.
Justin had earned a reputation for figuring things out and getting people out of otherwise hopeless situations. Many of his classmates and neighbors sought him out when they needed help with a problem. On the first day of school, his friend Kenny, came looking for Justin.
“Do you think you have something in your bag that could help me remember my locker combination?” he asked. “I lost the piece of paper it was written on. I have a science class in two minutes and if I’m late on the first day it’ll make me look bad for the rest of the year.” Kenny looked really worried.
“Relax,” Justin said, taking his backpack off and unzipping the top. “Remember how you borrowed my notebook in homeroom to write the combination down? Well, I know how we can recover what you wrote.”
He took the notebook and a soft lead pencil out of his bag. The page that Kenny had written on had left faint marks on another page in the notebook. Justin held the pencil on its side and rubbed it lightly over the marks. Slowly but surely the numbers of the locker combination appeared in white, set off by the gray pencil rubbings.
“That’s amazing!” Kenny said. “I owe you one.” And he dashed off to open his locker.
It was just another day in the life of the boy whose motto was “Never throw anything out, you never know when it might come in handy.”Why is Justin’s room such a mess? WWW.K**S*858$$U.COM

A long time ago, before there was any money (coins or paper money), people got the things that they needed by trading or exchanging. Salt was one of the first items used to exchange for other items. Later, some of the common things that were used for exchanging were tea leaves, shells, feathers, animal teeth, tobacco, and blankets. Around 3000 BC, barley, a type of grain, was used for exchanging.
The world’s first metal money was developed by the Sumerians who melted silver into small bars all weighing the same. This was around 1000 BC. About three hundred years later, people started using coins as official money.
Around 640 BC, people in the ancient kingdom of Lydia ( which was in Turkey) created special coins of exact with and purity (纯度). They were made of gold and silver and were stamped with a lion’s head.
Later, other empires such as Greece, Persia, and Rome adopted the concept of coins and started developing their own in many different shapes and different metals.
Around the year 1000, the Chinese started using paper money. The Chinese were the first to use paper money. The Europeans discovered this thanks to Marco Polo who went to China in 1295. the Chinese had different values for the paper notes which were made by the Chinese government.
Around 1661, Sweden became the first European country to make paper money. Until 1850, the Spanish dollar was the coin most widely used throughout the world.

Having reached the highest point of our route according to plan, we discovered something the map had not told us. It was impossible to climb down into the Kingo valley. The river lay deep between mountain sides that were almost vertical（垂直）.We couldn’t find any animal tracks, which usually show the best way across country, and the slopes were covered so thickly with bushes that we could not see the nature of the ground. We had somehow to break through to the river which would give us our direction out of the mountains into the inhabited lowlands.
Our guide cut a narrow path through the bushes with his long knife and we followed in single file. Progress was slow. Then, when we thought we had really reached the river, we found ourselves instead on the edge of a cliff with a straight drop of 1,000 feet to the water below. We climbed back up the slope and began to look for another way down. We climbed slipped, sweated and scratched our hands to pieces and finally arrived at the river. Happily we came downhill along its bank without having to cut our way. However, after a few miles the river entered a steep-sided gap between rocks and suddenly dropped thirty-five feet over a waterfall. There was no path alongside it and no way round it.
Then one of the guides saw a way of overcoming the difficulty. There was a fallen tree lying upside down over the waterfall with its leafy top resting on the opposite bank below the falls. Without hesitation he climbed down the slippery trunk to show us how easy it was. Having got to the fork of the tree, he moved hand over hand along a branch for four or five feet with his legs hanging in space, then he dropped onto the flat bank the other side, throwing his arms in the air like a footballer who has scored goal, and cheerfully waving us on.
74．Having reached the highest point on their route, the travelers expected to be able to .
A．track animals to the river
B．put away the maps they had been using
C．come near to the river from a different direction
D．get down to the river without much difficulty.
75．The travelers wanted to get to the river because .
A．it would lead them to the waterfall
B．it would show them which way to go
C．it was the only possible way out of the mountains
D．it was a quicker way than going over the mountains
76．One reason why the travelers took so long to get to the river was that .
A．it was too hot to move quickly
B．there was no proper path
C．they all tried to go different ways
D．they could not follow the animal tracks
77．To get past the waterfall the guide had to .
A．use a fallen tree as a kind of bridge
B．cross the river above the waterfall
C．slide down a steep river bank
D．swing across the river from a high branch

WASHINGTON -Tofu（豆腐）and Soyaburgers (豆饼) may be coming to American school lunch menus. What will the kids say? “Terrible,” said Greg Dudzinski, 17, of Ripon High School in Wisconsin, as he toured the US capital.
“The regular hamburgers are bad enough, so soyaburgers would be a lot worse, offered Zach Richey, 13, of Scottsboro Junior High in Alabama, another tourist. But the United States government – hoping to reduce the amount of fat that children are eating –has approved the use of soy as a meat substitute in meals for schools and day-care centers.Not all kids dislike the change. Mariel Spano, 17, of sandy Greek High School in New York, also visiting the capital, said she likes soyaburgers：“There is less fat, and they are better for you… They taste the same, and they are just as good.”
The government tried to make soy a meat substitute nearly 20 years ago, but later dropped the idea．At the time, the plan was intended as a cost-cutting move. US Agriculture Department officials say that their purpose now is only to make meals healthier.Schools are likely to increase the amount of soy that is mixed with hamburgers and other foods already on their menus, and they will also be looking for food companies to develop new soy products that children will like. “I can’t see putting tofu on a student’s plate and having a good acceptance. I can see taking a product that is familiar to the students and adding a large amount of soy to it and having it to be acceptable,” said Jill Benza, director of food services for the Mesa, Arizona schools.
36．What is the newspaper report mainly about?
A．The difficulty in using soy products for US schools.
B．Various opinions on soy products for US schools.
C．The plan that is made by the US government for school lunch.
D．Healthy foods for students in US schools.
37．Where did the interviews most probably take place?
A．In food companies. B．In schools.
C．In Washington. D．In some other states.
38．We may learn from the text that _________________________.
A．soyaburgers taste better than hamburgers.
B．hamburgers are healthier than soyaburgers.
C．soyaburgers cost less than hamburgers.
D．hamburgers cost less than soyaburgers.
39． What Jill Benza said shows that ___________________________.
A．students have not yet been used to soy products.
B．it is hardly possible to make soy products popular.
C．he does not like the change in meals for students.
D．schools are unwilling to change the lunch menus.
People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.
However, Dr. Michael A.McDaniel emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein’s brain was “ not particularly large,” McDaniel noted “ There’s some relationship between brain size and intelligence on average, but there’s plenty of room for exceptions,” he said.
Interest in the relationship between brain size and intelligence grew in the 1830s, when German anantomist(解剖学家)Frederick Tidemann wrote that he believed there was “ a natural connection between the size of the brain and the mental energy displayed by the individual man.” Since that statement, scientists have conducted numerous studies to determine if Tidemann’s idea was , in fact, correct. Most studies have investigated the link between head size and intelligence .More recently, however, researchers have published additional studies on intelligence and brain size, measure using MRI scans
.
For his study, McDaniel analyzed more than 20 studies that investigated the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on average, people with larger brain volume tended to be more intelligent. The relationship was stronger in women that men, and
adults than children ,McDaniel noted.
In an interview, McDaniel noted that he’s not sure why the relationship was stronger for adults and women. Previous research has shown that women, on average, tend to have smaller brains that men, but score just as well--- if not higher--- in tests of intelligence he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-brained people who are highly intelligent,” he said” But , on average, the relationship holds.”
73．What does the passage mainly tell us?
A．The success of using MRI scans for studies on man’s intelligence.
B．On average bigger brains mean higher IQ.
C．The importance of our brain volume.
D．Dr. Michael succeeded in his studies on man’s intelligence.
74．By mentioning Albert Einstein, the writer wanted to show ___.
A．what Albert Einstein achieved had nothing to do with his brain size
B．probably the studies on man’s intelligence are not worth believing
C．why hard working is more important than intelligence.
D．the results of thes
e studies are not true for everyone
75．The underlined word “investigated “ could be replaced by ____.
A．worked our B．guessed C．study D．imagined
WHAT can help you make a fortune in the future? Graduating from a top university might not be enough．A new study from the University of Essex in Britain has shown that the more friends you have in school, the more money you’ll earn later．
The idea that popularity could have a serious impact on one’s earning potential shouldn’t come as too much of a surprise．The researchers noted that if you want to get_ahead in life, social skills and networking are easily as powerful as talent and hard work．
“If a person has lots of friends, he or she has the ability to get along with others in all kinds of different situations,” said Xu Yan, 17, from Nantou High School in Shenzhen, who totally agreed with the recent finding．“Also, friends always help each other．They not only create wider social circles for you but lift your mood when you occasionally feel depressed．” She believed that all this helps you “earn a higher salary”．
Maybe that’s why some people think the younger generations are in the age of Friendalholism （交友狂症）．A woman even complained that the networking website Facebook’s 5000-friend limit was too low for her large reserve of social contacts．
But Meghan Daum, who works with The Los Angeles Times in the US, disliked the idea that quantity trumps （胜过） quality in the age of Friendaholism．“Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom I enjoy actually seeing．” said Daum．She admitted that some Internet social networkers just want to get as many of not-really-friends as possible．Although she agreed that social ties grease （润滑） the wheels of life, she also warned, “Finding a real friend is something that really matters．”
63．What CANNOT be learned about friends from the passage?
A．They enlarge social circles for you．
B．They offer encouragement when you are upset．
C．Only talented friends help you to earn success．
D．Friends enable you to overcome difficulties．
64．In the age of Friendalholism, ________．
A．there are networking websites to help people make friends
B．a person with popularity is sure to enter a top university
C．facebook helps social networkers make as many friends as possible
D．there are always more not-really-friends than actual ones
65．The underlined words probably mean ________．
A．expect B．struggle C．graduate D．succeed
66．Meghan Daum holds the attitude towards making friends that ________．
A．actual friends outweigh not-really-friends
B．the more friends one has, the better
C．friends can help make a big fortune
D．social relations can hardly make one’s life better
People living in the UK take quite a few holidays abroad and in this country each year. Choices made about where to go, how to get there and what to do while there can either benefit or harm the environment.
While on holiday
Many of the things you can do to be greener on holiday will be the same things you can do at home—but there are also some extra things too, like avoiding gifts made from endangered plants and animals. Here are some suggestions:

My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half-playful, half-serious way I knew so well, he said, "How would you like to go to Eton?" "You bet," I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. Besides, even at 12 or 13, I understood my father. He disliked any form of showing off. He always knew his proper station in life, which was in the middle of the middle class, our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-hand Rolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100. This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict（冲突） with his fear of drawing attention to himself. It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Graham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging（刺痛） and my hands shaking with the puzzlement of my feelings. There was excitement, at the heart of great sadness. "Oh, he doesn't want to go away," said my mother, "You shouldn't go on like this.” “It's up to him," said my father. "He can make up his own mind." His father sold his Rolls-Royce because ________.
| A．it made him feel uneasy | B．it was too old to work well |
C．it was too expensive to possess | D．it was too cheap |
The writer's father enjoyed being different as long as ________.
| A．it drew attention to him | B．it didn't bring him in arguments |

What was the writer's reaction to the idea of going to Eton?
| A．He was very unhappy. | B．He didn't believe it. |
C．He was delighted. | D．He had mixed feelings. |
We can know from the passage that ________.
| A．Children who can go to Eton are very famous |
B．Children can go to Eton if they will |
C．It is very difficult for a child to get admitted by Eton |
D．Children don't have the right to decide whether they will go to Eton |
Handwriting reveals a great deal about how an individual thinks, since the brain dictate (发号施令) hand movements when a person writes. People who think quickly will write quickly, while people whose thinking is slow will write in the same way. Sometimes we see very elaborate (精致的) handwriting, particularly among public figures, such as actors or politicians, who want to draw attention to themselves. For them, handwriting is like a dress that enables them to stand out from the crowd.
The handwriting of someone who is suited to a routine job will appear well organized, clear, and regular, without any special features drawing attention to it. If the job requires proven accuracy, like that of an accountant(会计), the handwriting, especially the numbers, should be precise. On the other hand, someone in sales or public relations must be self-assured, know how to make a good impression, and be able to befriend people even when meeting them for the first time. The handwriting of such individuals will appear rather large, with elaborate capitals and on oversized signature. It will be quick, fluent, and not necessarily reasonable.
Handwriting analysis can be used to find potential behavioral or personality problems. People who are impulsive, aggressive, or dishonest write differently than those who are socially well adapted. Warning signs include broken and strongly or sporadically (零散的) pressured handwriting; disorderly handwriting in which the words run over the lines on the paper, or extremely sharp handwriting. Generally, handwriting that is extreme in any aspect-too small, too weak or too pressured-is suspect.
Evidence of medical problems also shows up in a person’s handwriting. Individuals in pain often stop in the middle of writing. Pauses will be visible in the handwriting of people who experience difficulty breathing, because they stop writing to take a breath.
Handwriting expresses the mental and physical state of the individual, as well. Depressed people write slowly, with lines sloping (倾斜) down and heavy pressure exerted(施加) on the page. People who are excessively excited will write quickly, and their handwriting will be extremely disorganized and practically unreadable. People who are tired tend to write lines that descend down the page, and their handwriting will appear weak and slow. Healthy and vigorous individual will write energetically, and their handwriting will be quick, rhythmic and fluent.
71. The passage is mainly about _____________.
A. what handwriting indicates
B. handwriting and personalities
C. the relationship between handwriting and the individual
D. handwriting analysis and the problems it shows
72. Suppose you are a famous pop star, your handwriting will be in the style of being_______.

73. If a person writes with a rather large, elaborate capitals and an oversized signature, we can conclude that he is probably a (an) __________.
A. famous person B. salesman C. doctor D. accountant
74. If you see disorderly handwriting, you will think that the person who writes it is ________.
A. depressed B. vigorous C. slow in thinking D. dishonest
75. According to the passage, a person’s handwriting has something to do with(与……有关) all of the following EXCEPT his______.
A. mind B. education C. health D. profession (职业)
Identifying young people with the potential to be great athletes has become a serious, business around the world. Many countries, including Australia, have sophisticated(复杂) programs for identifying and nurturing(培养) talent.
The AIS (Australian Institute of Sport) already runs a program that identifies potential winners starting from the age of 12 based on their physical and physiological(生理的) abilities.
Could genetics improve these programs? The problem is that no one gene test is ever going to do an accurate job of identifying someone with the physical attributes of a sporting champion, says Professor North.
"We can think of the elite athlete as what I'd call a complex phenotype(表现型)," she says. “There are going to be a large number of different genes involved. Any one single test is unlikely to be highly predictive.”
Professor Peter Fricker, director of the AIS, agrees. Although he is intrigued in the possibilities of genetic testing, he says using such tests to identify athletes would be difficult. "The feeling I have is that it won't be that easy," he says. "Talent selection is not just about your genes."
Since 2004, the AIS has been forbidden by government from any involvement in genetic work, including genetic testing. But Professor Fricker thinks that is likely to change in the near future. "There's been a shift in view more recently," he says.
When it does, the AIS will resume its work on the genetics of sports performance, Professor Fricker says. They would be particularly interested in looking for more genes that might help shape elite performance, but also for genes that increase the risk of injury.
Last year, the Human Genetics Society of Australasia issued a position statement on gene testing for sport, after concerns that people could use tests to steer children into particular sports.
“The Human Genetics Society thinks there are not enough data to use these tests for determining what sport kids should do,” said Professor David Thorburn, president of the society.
He stressed that genetic tests should not be performed on children, except in very specific medical circumstances.
57．The aim of the AIS’s program is to .
A．predict how genes are connected with injuries
B．find potential great athletes
C．find out what qualities a professor has through gene tests
D．turn an athlete into a champion by transferring genes
58．By saying “Talent selection is not just about your genes”, Fricker means .
A．effort is more important than genes in most cases
B．you can’t choose an athlete just depending on genes
C．to research one’s genes takes a long time
D．most people don’t believe in genetic tests
59．The underlined word “resume” in Para. 7 can be replaced by .
A．stop B．complete C．reduce D．continue.
60．What’s Professor David Thorburn’s attitude towards genetic tests?
A．Genetic tests have a negative effect on children.
B．Genetic tests, under certain conditions, can be conducted on children.

Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one.
The closest that Herpin came to resting was to sit in a rocking chair(摇椅) and read some news papers. The doctors were puzzled by this strange continuous sleeplessness.

The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(层)just under the surface.The outside dead layers wear off(磨损)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.
The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.Which of the following statements is NOT true?
| A．Our hair and nails are dead like the surface of the skin. |
| B．There is skin all over our body. |
| C．The skin of our bodies will be completely different in three weeks. |
| D．The surface of the skin is made of a living layer. |

| A．the functions of the skin |
