Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt (柏油) roads?
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 ran 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.

There was great excitement on the planet of Venus (金星). Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week's satellite landing,” Prof. Zog said, “that there is no life on Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won't this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金).” Profession. Zog replied.
【小题1】According to the passage, the Venusian scientists succeeded in getting important information about ________.
A.the feasibility of landing a satellite on Earth |

In Egyptian myth, Apophis was the ancient spirit of evil and destruction, a demon (恶魔) that was determined to throw the world into darkness forever. A fitting name, astronomers reasoned, for a threat now rushing towards Earth from outer space. Scientists are monitoring the progress of a 390-metere wide asteroid (小行星) discovered last year, which is potentially on a collision (碰撞)course with the planet.
NASA has estimated that Apophis has an outside chance of hitting the Earth in 2036. If it did hit us, thousands of square kilometers would be directly affected by the explosion but the whole of the Earth would see the effects of the dust sent into the atmosphere. At a recent meeting of experts in Near-Earth objects (NEOs) in London, scientists said it could take decades to design, test and build the required technology to deflect the asteroid.
The Apophis asteroid is placed at four out of ten on the Torino scale—a measure of the threat caused by an NEO where 10 is a certain collision which could cause a global disaster. This is the most possible danger of any asteroid in recorded history and it has a 1 in 37 chance of hitting the Earth.
Alan Fitzsimmons, an astronomer from Queen’s University Belfast, said, “When it does pass close to us on April 13, 2029, the Earth will deflect it and change its orbit. There is a small possibility that if it passes through a particular point in space, the so-called keyhole, the Earth’s gravity will change things so that when it comes back around again in 2036, it will collide with us.” The chance of Apophis passing through the keyhole, a 600-meter patch of space, is 1 in 5,500, based on current information.
There is no shortage of ideas on how to deflect asteroids. The Advanced Concepts Team at the European Space Agency has led the effort in designing a range of satellites and rockets to nudge asteroids that are on a collision course for Earth into a different orbit.
【小题1】The best title for this passage would be ___________.
A.Apophis Asteroid, a Possible Destroyer of Earth |
B.Apophis, a Good Name for Dangerous Asteroid |
C.Our Planet Will Be Ruined in 2036 |
D.Scientists Study Apophis Asteroid |

Pigs are always considered dirty animals because they roll in mud.But in fact they prefer being quite clean.They cover themselves with mud to help stay cool.During cooler weather, they prefer to stay clean.So do elephants, who also cover themselves in dust or mud to keep cool.When they find a place with clean water they will take a bath,using their long noses to give themselves—or each other—a nice shower
Some animals use dust to get clean.Chinchillas (南美洲栗鼠) have very fine fur. They don’t like to take water baths because water is not warm enough for them.So, instead, they roll around in fine dust.The dust helps to keep their fur and skin dry.This protects them from disease
Usually, a small bird is a light meal for a crocodile.But when a crocodile wants its teeth cleaned.it lies on the ground with its mouth open.The crocodile bird goes in and picks out any parasites(寄生虫)between the crocodile’s teeth or under its tongue.The crocodile gets its mouth cleaned,and the crocodile bird gets dinner.
You wouldn’t think fish would need baths.But some undersea parasites live under the fish’s skin.“Cleaner” fish,like the wrasse(隆头鱼),help take them away.The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business.The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out parasites and bits of food.
【小题1】The passage is mainly about how animals __________.
A.stay clean | B.help each other | C.get their food | D.take baths |
A.They can help each other take baths. |
B.They are dirtier during cooler weather. |
C.They prefer taking baths to rolling in mud. |
D.They like to stay cool and clean. |
A.dust can dry their fur and skin | B.They are not good at swimming |

There are some things humans can go without. We can lose a kidney (肾)or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.
One such fish is the stout longtom(尖嘴魚 ). The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical(热带) fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. Its teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin(胰岛素) that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.
【小题1】What does the underlined phrase “get by” mean?
A.Live. | B.Fight. | C.Hunt. | D.Recover. |
A.catches smaller fish in the water |
B.can jump so high to escape its enemies |
C.digests the smaller fish in its body |
D.uses acid to break down the protein |
A.Acid | B.Trypsin. | C.The stomach. | D.Protein in its body. |
A.the longtom often waste energy |
B.the longtom can make acid easily |
C.the longtom’s high-protein food helps its unique way of consuming food. |
D.meat-eating fish have higher levels of trypsin in their bodies than plant-eating fish |

“iPhone 5”, the tallest thing to happen to iPhone since iPhone
We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (显示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快门). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!
【小题1】How is the screen of “iPhone 5” different from the previous ones?

Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city.However, there’s something different about riding a London subway.It may not look different, but the historical value of one of England’s most popular forms of transportation is enough to make riding the subway a must when visiting London.With a little under 100 different stations, the subway can take you almost anywhere you need to go.
Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other.In fact, eye contact is avoided at all times.That’s not rudeness―people are just too busy to bother looking.
Busy doing what, you ask? Well, they’re certainly not using the time for a moment of quiet thinking.Nor are they reading a book.New technology has replaced quiet habits.Today the only acceptable form of book on the London underground is an e-book.
Apple must earn a fortune from London commuters(使用月票上下班者).Since the launch of the iPhone in 2007, over 40,000―yes, that’s 40,000 “apps” have been designed.
Commuters love them because they are the perfect time-fillers.One “app”, called iShoot, is a game that features tanks.Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination.iSteam clouds the iPhone screen when you breathe into the microphone.You can then write in the “steam” on your phone screen.
For those without an iPhone, another Apple product, the iPod, may be the distraction(消遣)of choice.It’s not just teenagers who “plug in” to their music-iPods are a popular way to pass the time for all ages.
And if games, e-books and music aren’t enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work.With all these distractions, it’s amazing that people still remember to get off the train.
【小题1】People in London do not make eye contact on the subway because ______.
A.they are going to work and have no time to communicate with each other |
B.they love reading books and do not want to be disturbed |
C.they feel sleepy because of getting up early |
D.they are busy playing games, reading e-books, listening to music or watching films |
A.computers | B.programs downloaded for the iPhone |
C.computer companies | D.fortune from London commuters |
A.iShoot | B.Tube Exits | C.iSteam | D.iPod |
A.London commuters are unfriendly to strangers |
B.Apple has earned a lot of money from selling 40,000 apps |
C.technology is changing how London commuters spend their traveling time |
D.riding a London subway is a must when visiting London |

People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions — and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly(均匀的) across a face as Westerners do, Easterners fix their attention on the eyes.
"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect (忽略) the mouth."
According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.
The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of. expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than did Westerners. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less."
In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don't clean it up, we may all be in mortal (致命的)danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(抛弃) things that no longer served any useful purpose in space.
It is estimated (估计)that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.
【小题1】What was the first piece of man-made space trash?
A.A camera. | B.A tool kit. |
C.A fuel tank. | D.A broken satellite. |
A.It no longer served any useful purpose. |
B.It was millions of miles away from the Earth. |
C.It did not cause any problems. |
D.It was regarded as similar to comets and stars. |
A.It is huge, heavy machines. |
B.It never changes position. |
C.It floats slowly around the Earth. |
D.It may cause problems for space shuttles. |
