Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer.He finally persuaded his boss to follow it up.The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes.Most of them run from one side of the street to the other, just under the asphalt road.Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes.At a depth of 100 meters lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built.The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe.The aquifer is thus used as a heat store.
In winter, the working system is changed slightly.Water is pumped through the heat exchangers to pick up the heat stored during summer.This water goes into the building and is used to warm the place up.After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

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, it means that he or she has the ability to get along with others in all kinds of different situations,” said Xu Yanchun, 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,” said Xu. 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 5,000-friend limit was too low for her large reserve of social contacts.
But what does a friend mean? Should friends be regarded as a form of currency?
“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. It seems, however, that this is no longer the definition of ‘friend’,” said Meghan Daum, who works with the Los Angeles Times in the US.
小题1:The new study from the University of Essex in Britain shows that _______.
A.if you have more friends you will not live happily |
B.the more friends you have in school, the more money you’ll earn in your late life |
C.the less friends you have, the poor lives you will live |
D.friends can make more money for you |
A.you have the ability to earn more money |
B.you will not feel lonely |
C.you are quite content with your life |
D.you have the ability to get along with others in various situations |
A.The passage mainly tells us something about the friendship. |
B.Friendship plays a more important part in our daily life than anything else. |
C.Friends are currency. |
D.Friends give you success. |
A.if you have more friends, you can make a fortune in the future |
B.graduating from college means that you can make a fortune in the future |
C.friends mean a form of currency |
D.friends can make you wider social circle and make you feel better when you feel depressed |
Spirit landed on Mars on January 4, 2004. Three weeks later, Opportunity arrived. Soon after, the rovers went to the opposite side of Mars. Spirit’s original mission was only designed to last for three months, but Spirit has worked for more than five years doing additional missions. Both rovers have made important discoveries about ancient Mars. They have taken thousands of images and found evidence in the rocks of a water, warmer past in Mars’ history.
Spirit is solar-powered. It got stuck in a sand trap in April 2009, trapped deep into the soil and with its wheels turning around and around but not able to move forwards or backwards. Spirit had to agree that there is nothing that can be done to change the situation—it’s never going to move again. However, even if it is a not moving station, it can still study the planet’s atmosphere and deep interior.
NASA has been concentrating on trying to position its solar panels to get as much energy from the sun as possible, or to get the rover leaning in a manner that will allow the most amount of sunlight falling on its solar panels, in order to keep it alive during the coming winter months. Engineers have planned to rock the vehicle back and forth to acquire a more favorable position. However, no matter how many efforts have been made, Spirit still could not get out of the soft soil and could not lean itself toward the sun as the Martian winter approached. Without enough energy reaching its solar panels and with so little energy in its batteries, it went into hibernation, just like a polar bear, and has not communicated with Earth since March 22, 2010.
Whatever the future holds for Spirit, its mission has been an outstanding success. When it landed on the Red Planet in January 2004, no one was really sure how long it would continue working in the cold and dusty environment. As a matter of fact, three months was its original goal.
After so many fruitless efforts, NASA scientists are losing hope of ever reconnecting with Spirit, but they will give it one more try. Ground controllers are contacting Spirit over a range of frequencies and at different times during the day in case its internal clock stopped working and it lost track of time. They also are commanding the rover to turn on its backup radio transmitter in case the main one is dead.
If this final effort to connect isn’t successful, NASA will shift the focus to its twin robot, Opportunity, which is in a different part of Mars. Opportunity is still on the move and continues to travel freely to this day. It has traveled 16.6 miles so far, and is currently rolling towards another crater it has yet to explore.
NASA has spent more than $900 million on the project but shows no sign of giving up on these determined and hard-working robots. The rovers are, though, experiencing gradual wear and tear, the expected damage to something caused by using it repeatedly over a period of time. Even before Spirit got trapped, one of its wheels had failed. And NASA says it’s just a matter of time before both robots break down completely.

Saying thanks not only brightens someone else’s world, but it also brightens yours. If you’re feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need.
Of course, there are times when you can’t express gratitude immediately. In that case don’t let embarrassment sink you into silence—speak up the first time you have the chance.
Once a young minister, Mark Brian, was sent to a remote parish of Kwakiutl Indians in British Columbia. He had been told that the Indians did not have a word for thank you. But Brian soon found that these people had exceptional generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks.
I wonder if we had no words in our vocabulary for thank you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive and more caring?
Thankfulness sets in motion a chain of reaction that transforms people all around us—including ourselves, for no one ever misunderstands the melody of a grateful heart.
小题1:In the first paragraph the writer mainly encourages us .
A.to express our sincere thanks timely to those around us |
B.never to overlook our close friends in daily life |
C.to wait for a proper occasion to show our gratitude |
D.to increase the world’s happiness by saying thanks |
A.is good for both us and people who help us |
B.benefits the people who do something for us |
C.wastes our and our friends’ time at the same time |
D.does harm to both us and people who help us |
A.seeing a doctor to find the right medicine we need |
B.expressing our gratitude in an easy way |
C.speaking up the moment we have the chance |
D.showing others actively we are willing to help them |
A.the Indians didn’t have any words for appreciation |
B.the Indians were particularly generous to others |
C.some people may express their gratitude through different approaches |
D.Mark Brain set the Indians an example to show saying thanks is very important |
Experts have realized the need to keep parents informed of the newer methods used in schools. Many headmasters have conducted workshops explaining such matters as the reading readiness, program writing and mathematics to parents.
Moreover, the classroom teacher, with the permission of the supervisors(管理者), can also play an important part in giving more knowledge to reporting pupils progress, teachers can help parents a lot in educating their children and parents can give much help to teachers.
Suppose that a father has been drilling Junior arithmetic lessons night after night. In a friendly talk between the teacher and the father, the teacher can help the parent to make Junior interested in it. He might be persuaded to let Junior join in discussing the family budget, buying the food, using a ruler or measuring cup at home, setting the clock, calculating the distance of a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to say that he will soon realize that his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.
Too often, however, teachers’ talks with parents are devoted to small accounts of children’s misdemeanors(不良行为). They talk about the laziness and poor work habits of the children.
What is needed is a more creative way in which the teacher, as an adviser, plants ideas in parents’ minds to make sure that the child spends the many hours out of the classroom learning something useful.
In this way the school and the home join forces in educating children.
小题1:The main idea of the passage is that ____.
A.home training is more important than school training |
B.parents should help their children to do their homework |
C.there’re many ways in which the mathematics program can be carried out at home |
D.teachers can and should help parents to use better ways to teach their children |
A.is satisfied with the relationship between school and home |
B.feels that parent-teacher talks can be made much more constructive |
C.believes that schools can’t teach pupils well |
D.calls on parents to teach their children mathematics at home |
A.Classes for parents. | B.New type of report card. |
C.Parent-teacher talk. | D.Dinner or party. |
A.interesting activities can improve one’s achievement |
B.too many children are lazy and have poor work habits |
C.teachers should often make home visits to parents |
D.headmasters do more than teachers in this area |
A.father’s helping his son with his study |
B.written reports to the parents from the teachers |
C.talking about children’s shortcomings |
D.having the parents help their children with their lessons |
If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get stranger answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www. intellicast. com.
Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I., Artificial Intelligence, he must overcome two problems.
The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process(处理) information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.
小题1:From the text we can infer that www. Intellicast. com is a website .
A.which is specially designed to help Smarter Child |
B.where we people can find Smarter Child |
C.where weather forecasts are made |
D.which is about artificial intelligence |
A.tell us how to spell a difficult word |
B.tell us how the American government is run |
C.provide us with a famous poem by Shakespeare |
D.learn how to tell right behaviors from wrong ones. |
A. Smart Child has his own memory bank big enough for all kinds of information.
B. A. I. Artificial Intelligence is probably the name of a film about a boy-computer.
C. Smart Child can recognize different files and find information needed on his own.
D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.
小题4:Which of the following is the best title for the passage?
A.A New Web Child | B.Smarter Child |
C.The Future of Internet | D.Intelligence Development |
