You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t   36   how quickly time has passed.
If you are familiar with this   37  , you’ll know how time flies when you are having fun and  38   when you are bored. Now scientists have   39   a reason why this is the case.
Scans have shown that patterns of activity in the brain   40   according to how we focus on a task. When we are   41  , we concentrate more on how time is passing. And this makes our brains   42   the clock is ticking more slowly.
In an experiment   43   by a French laboratory, 12 volunteers watched an image   44   researchers monitored their brain activity.
The volunteers were told to   45   concentrate on how long an image appeared for, then  46   the color of the image, and thirdly, study both duration and color. The results showed that  47   was more active when the volunteers paid   48   subjects.
It is thought that if the brain is   49   focusing on many aspects of a task, it has to  50  its resources, and pays less attention to the clock.  51 , time passes without us really   52   it, and seems to go quickly. If the brain is not so active, it concentrates its   53   energies on monitoring the passing of time.   54  , time seems to drag.
Next time you feel bored   55  , perhaps you should pay more attention to what the teacher is saying!

The Best of Friends
The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image(印象)of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team.” They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商議) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall.” I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.”Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework ,I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments,” Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
小題1:What is the popular images of teenagers today?
A．They worry about schoolB．They dislike living with their parents
C．They have to be locked in to avoid troublesD．They quarrel a lot with other family members
小題2:  The study shows that teenagers don’t want to ___

小題3: Compared with parents of 30 years age, today’s parents___.
A．go to clubs more often with their childrenB．a(chǎn)re much stricter with their children
C．care less about their children’s lifeD．give their children more freedom
小題4: According to the author, teenage rebellion____.
A．may be a false beliefB．is common nowadays
C．existed only in the 1960sD．resulted from changes in families
小題5:What is the passage mainly about?
A．Negotiation in familyB．Education in family
C．Harmony in familyD．Teenage trouble in family

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part －drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (遠(yuǎn)距離的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (螞蟻) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
小題1:Watchers doubted if any of the vehicles could finish the race because        .
A．they did not have any human guidance
B．the road was not familiar to the drivers
C．the distance was too long for the vehicles
D．the prize money was unattractive to the drivers
小題2:DARPA organized the race in order to         .
A．raise money for producing more robotic vehicles
B．push the development of vehicle industry
C．train more people to drive in the desert
D．improve the vehicles for future wars
小題3:From the passage we know “robotic vehicles” are a kind of machines that         .
A．can do effortlessly whatever tasks living thing can
B．can take part in a race across 142 miles with a time limit
C．can show off their ability to turn themselves upside down
D．can move from place to place without being driven by human beings
小題4:In the race, the greatest distance one robotic vehicle covered was          .
A．a(chǎn)bout eight miles B．six miles
C．a(chǎn)lmost two miles D．a(chǎn)bout one mile
小題5:In the last paragraph, the writer implies that there is a long way to go         .
A．for a robotic vehicle to finish a 142-mile race without any difficulties
B．for a little child who has just learned to walk to reach the cookie on the table
C．for a robotic vehicle to deal with a simple problem that a little child can solve
D．for a little child to understand the importance of wiping apple juice off its face

Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle.
There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(凝結(jié)). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes, and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle(水坑) or pond in a mist(薄霧) above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It continues even if snow or hail(冰雹) fall instead because both eventually melt to form water. The amount of water vapour in the air depends on the temperature. The air is more moist(潮濕) in the tropics(熱帶) than in the cold polar regions.
小題1: What is the main idea of the passage?
A．Water cycle.B．Water vapour.
C．How rain forms. D．Water, vapour, rain.
小題2:How many ways of the water returning to the air are discussed in the text?
A．Two. B．Three.C．Four.D．Five.
小題3:Whether water vapour can be seen or not depends on _______.
A．how much water is evaporatedB．how good your eyes are
C．in which way water is evaporatedD．climate or weather
小題4: From the passage we get to know _______.
A．there is more water vapour in the air in the tropics than in cold polar regions
B．there is more water vapour in the air in cold polar region than in the tropics
C．it gets more rain in the tropics than in cold polar regions because there is less vapour
D．the amount of water vapour in the air depends on how often it rains

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.
On one side stand those who see clothes dryers(干衣機(jī)) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I –can do environmentalism(環(huán)境保護(hù)主義).”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) access the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.
So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be move.
Matt Reck, 37, is the kind of eco-conscious(有生態(tài)意識的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighlzir had telephoned them about him clothesline. The Recks paid no attention to the warming and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.”
小題1:One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ____.
A．clothes dryers are more efficientB．clothesline drying reduces home value
C．clothes dryers are energy-savingD．clothesline drying is not allowed in most U.S. states
小題2:Which of the following best describes Matt Reck?
A．He is a kind-hearted man.B．He is an impolite man.
C．He is and experienced gardener.D．He is a man of social responsibility.
小題3:Who are in favor of clothesline drying?
A．housing businesses.B．Environmentalists.
C．Homeowners Associations.D．Reck’s dissatisfied neighbors.
小題4:What is mainly discussed in the text?
A．Clothesline drying: a way to save energy and money.
B．Clothesline drying: a lost art rediscovered.
C．Opposite opinions on clothesline drying.
D．Different varieties of clotheslines.

For £12 you can equip an entire classroom in Burkina Faso, for £31 you can equip a school football team in Sierra Leone and for £68 you can support the whole education of a Haitian schoolgirl.
The educational presents are the latest way on the trend of charitable（慈善的）giving for Christmas. Plan UK, an international children's charity, has made its gift list focusing on helping the world's poorest countries to improve their education conditions.
"Every year we rack our brains for the perfect present and too often end up with yet another pair of socks or a useless ornament," said Marie Staunton, Plan UK's chief executive.
"This year we are offering people in the UK the chance to give twice. Buying an alternative gift for a loved one could likely save the life of some of the world's poorest children."
Plan UK is working on projects in specific countries, such as Burkina Faso, which is one of the poorest countries in the world and has a primary school enrolment rate（入學(xué)率）of just 36%. A present of £12 will help equip a classroom in Burkina Faso with chairs, desks, books and pencils.
The educational presents are the latest addition to a list of other charitable presents, including vaccinations（接種）and clean water systems.
Football strips for schoolchildren in Sierra Leone are designed to help the children have fun while continuing with the psychological healing process following the country's civil war. The £31 gift will supply the team strip, a football and a whistle to a school in Sierra Leone.
Oxfam offers similar gifts. Its Back to School kits for five pupils is a bestseller in a catalogue（目錄）which includes the £24 Christmas goat, the £30 lavatory and £12 for school dinners for up to 200 children.

It is common to consider learning as something that takes place in school, but much of human learning occurs outside the classroom, even from birth and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human-service workers need to understand how certain experiences change people’s behaviors. Employers, politicians, and advertisers make use of the principles of learning to affect the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain. Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later outputs knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences.
小題1:The author thinks “Learning”in the passage most refers to_________.
A．life-long learningB．family learning
C．learning after graduationD．behavior learning
小題2:The underlined siblings in the second paragraph probably means______.
A．teachersB．classmatesC．doctorsD．brothers or sisters
小題3: Which period of children’ life does they begin to how to behave well according to the passage?
A．After they go int society
B．Before they enter school
C．When they are at school
D．Before they are born
小題4:Which of the following is WRONG according to the passage?
A．As a matter of fact, learning begins with formal school education
B．Teachers need to understand the best ways to educate their students.
C．People need to understand how certain experiences change their behaviors.
D．Employers should study the principles of learning to manage their workers well.
小題5:The author tries to tell us ______in the last paragraph
A．learning is closely related to memory and experience
B．psychologists are interested in the wat the brain stores knowledge
C．psychologists are more interested in a person’s behavior
D．the relationship between learning, brain and behavior

The mobile phone has been a part of our lives since the 1980s. It enables us to stay in contact with our family and friends at all times and in most areas. However, because of the quick acceptance and extensive usage of mobiles in our lives, we have missed out on an important step, namely, the appropriate (恰當(dāng)?shù)?use.
Driving a car  
Do not use your phone while you are driving ! You could concentrate on your conversation and forget to look where you are going, or you could take your eyes off the road to look at the phone’s display or to press in a number. Either way, you could cause a terrible accident.
In a restaurant
There is probably nothing more annoying than a diner receiving or making a call near you when you are in a restaurant. The icy glares you receive should be warning enough that it is not appreciated. Turn you phone off and enough that it is not appreciated. Turn you phone off and use your message service to return calls after you leave.
At the cinema
Do not give way to the desire to call a friend if the film is boring, or if you want to find out what happens. You could become the target of all the angry cinema customers.
At the theatre
There is no more icy glare than that of a theatre goer who has paid a lot of money to see a show and hears your phone playing a tone. It goes without saying that you will be seen as a socially unacceptable person in this situation.
In hospitals
This is probably the most important place to make sure your phone is switched off. Your phone can disturb life-saving electronic equipment in hospitals, so it is necessary that your phone is switched off before you enter.
On planes
Your phone might disturb navigational equipment and cause a horrible accident so you should switch it off before boarding a plane.
小題1:According to the passage, the most annoying thing in a restaurant is that __________.
A．you receive icy glares
B．a(chǎn) nearby diner is answering a phone call
C．you have to use the message service
D．you can not return calls until after you leave
小題2:Which of the following statements is NOT true ?
A．Theatre goers will not give you icy glares when they hear your phone.
B．When switched on in hospitals, mobile phones could endanger patients’ lives.
C．Passengers should switch off the phones before getting on a plane.
D．Pressing in phone numbers when driving could lead to traffic accidents.
小題3:The passage mainly describes __________.
A．different functions of mobile phones
B．the overuse of mobile phones on some occasions
C．some areas where message service is forbidden
D．the proper use of mobile phones in some public places
小題4:What does the underlined word “concentrate on” mean in the article? It means ______.
A．make something strongerB．carry on
C．pay particular attentionD．think something clearly

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (標(biāo)簽). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
1. The article is intended to______.  
A. warn people of the possible risks in adopting RFID technology
B. explain the benefits brought about by RFID technology
C. convince people of the uses of RFID technology
D. predict the applications of RFID technology
2. We know from the passage that with the help of RFID tags, people        .
A. will have no trouble getting data about others
B. will have more energy for conversation
C. will have more time to make friends
D. won’t feel shy at parties any longer
3. Passive RFID tags chiefly consist of        .
A. scanning devices              B. radio waves   C. batteries              D. chips
4. Why are some people worried about RFID technology?
A. Because children will be tracked by strangers.
B. Because market competition will become more fierce.
C. Because their private lives will be greatly affected.
D. Because customers will be forced to buy more products.
5. The last paragraph implies that RFID technology        .
A. will not be used for such matters as buying milk
B. will be widely used, including for buying milk
C. will be limited to communication uses
D. will probably be used for pop music
