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 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.
Which of the following is true according to the first two paragraphs?

A.Arian de Bondt got his idea from his boss.
B.Large, flat, black surfaces need to be built in cities.
C.The Dutch engineer's system has been widely used.
D.Heat can also be collected from asphalt roads.

For what purpose are the diving pipes used?

A.To absorb heat from the sun. B.To store heat for future use.
C.To turn solar energy into heat energy. D.To carry heat down below the surface.

From the last paragraph we can learn that ________.

A.some pipes have to be re-arranged in winter
B.the system can do more than warming up the building
C.the exchangers will pick up heat from the street surface
D.less heat may be collected in winter than in summer

What is most likely to be discussed in the paragraph that follows?

A.What we shall do if the system goes wrong.
B.What we shall do if there are no asphalt roads.
C.How the system cools the building in summer.
D.How the system collects heat in spring and autumn.

Using a computer or smartphone at night can cause us to pile on the pounds,new research has revealed.
The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger.It found that exposure to blue light increases hunger levels for several houus and even increases hunger levels after eating a meal.Blue light exposure has also already been shown to cause decreased sleepiness in the evening,increasing the risk of sleeplessness.
The leading researcher,Ivy Cheung,from Northwestern University in Chicago,said,“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢).These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism.”
The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions,which involved exposure to less than 20 lux(勒克斯,照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep.On the third day they were exposed to three hours of 260 lux,blue-enriched light starting10.5 hours after waking up, and the effects were compared with dim light exposure.
Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure,hunger and metabolism.
What is Paragraph 2 mainly about?

A.How blue light exposure affects hunger.
B.Why blue light exposure influences sleepiness.
C.What is the link between blue light exposure,hunger and sleepiness.

The search for beauty spans centuries and continents. Paintings of Egyptians dating back over 4,000 years show both men and women painting their nails and wearing makeup. In 18th-century France, wealthy noblemen wore large wigs (假发)of long, white hair to make themselves attractive. Today, people continue to devote a lot of time and money to their appearance.
There is at least one good reason for the desire to be attractive:beauty is power. Studies suggest that good-looking people make more money, get called on more often in class, and are regarded as friendlier.
But what exactly is beauty? It's difficult to describe it clearly, and yet we know it when we see it. And our awareness of it may start at a very early age. In one set of studies, six-month-old babies were shown a series of photographs. The faces on the pictures had been rated for attractiveness by a group of college students. In the studies, the babies spent more time looking at the attractive faces than the unattractive ones.
The idea that even babies can judge appearance makes perfect sense to many researchers. In studies by psychologists, men consistently showed a preference for women with larger eyes, fuller lips, and a smaller nose and chin while women prefer men with large shoulders and a narrow waist. According to scientists, the mind unconsciously tells men and women that these traits —the full lips, clear skin , strong shoulders —equal health and genetic well-being.
Not everyone thinks the same way, however. “Our hardwiredness can be changed by all sorts of expectations —mostly cultural,” says C. Loring Brace, an anthropologist at the University of Michigan. What is considered attractive in one culture might not be in another. Look at most Western fashion magazines: the women on the pages are thin, but is this "perfect" body type for women worldwide? Scientists' answer is no; what is considered beautiful is subjective and varies around the world. They found native peoples in southeast Peru preferred shapes regarded overweight in Western cultures.
For better or worse, beauty plays a role in our lives. But it is extremely difficult to describe exactly what makes one person attractive to another. Although there do seem to be certain physical traits considered universally appealing, it is also true that beauty does not always keep to a single, uniform standard. Beauty really is, as the saying goes, in the eye of the beholder.

A.have existed since ancient times

Would you like to be an actor, but aren’t the right age or physical type for the part? Don’t give up: there may be a place for you in the world of voice-acting.
Twenty-year-old Rickey Collins brings Tucker Foley to life in the cartoon Danny Phantom. In addition to many appearances on television and in movies, Rickey is a voice-over actor, someone we hear but don’t see. Rickey has acted since he was 6, both on and off camera. After school, his grandmother-- a manager and acting coach--helped him develop his skills by doing voice exercises and reading aloud.
Voice-over actors do many kinds of acting. They are the voices of cartoon characters on television, in movies and video games, and for communicating toys. In films, they replace the foreign language conversation with English version. They create crowd noises, make commercials, act in radio plays, and record telephone instructions and public announcements. They read books on tape and even record museum tours.
Like other actors, voice-over actors need to understand scripts, interpret characters, and breathe correctly. They have to master voice techniques, such as pacing, volume, and range. Sometimes they use their normal voices; other times they change their voices to create different characters or noises. Rickey receives his Danny Phantom scripts only a few days before he tapes each episode(集). He writes helpful notes on the script to guide himself on speaking his part.
Rickey practices, then tapes at the recording studio. He and the other cast members sit in a soundproof booth, acting out their characters as they read their lines into the microphones. “The cartoon gets created after we record the words, so we have to imagine everything in our mind,” says Rickey. Later, the recorded words, music, and sound effects are combined with the cartoon art to create the cartoon we enjoy on TV. Sound interesting? Maybe you can have a “voice” in acting after all!
The underlined sentence in paragraph 2 means _______.

A.Rickey draws the character
B.Rickey names Tucker Foley
C.Rickey makes the character seem real

Tragedy struck for brothers Rob and Paul Forkan when they lost their parents in the 2004 Asian tsunami. Now, over ten years later, they're using their flip flop business to help other orphans.
The boys had an unusual childhood. They were just 11 and 13 when their parents, Kevin and Sandra, took them out of the UK education system and moved the family to Goa in India. Their parents were of the philosophy that they would receive a healthier and fuller education by traveling the world and helping others. There they did lots of voluntary work and mixed with the local community. It was when the family were on holiday in Sri Lanka that the tsunami hit. Although the children managed to escape, their parents tragically couldn't. But Paul says their upbringing meant they were able to cope with this tough blow. "Our parents gave us this confidence that we could do anything, that nothing was hard to achieve," says Paul.
What the boys did was to start a business selling ethically-sourced sandals. They're called 'Gandys' after the father of India's independence movement, Mahatma Gandhi. "He was in all our schoolbooks as kids; he's on all the money over in India; he's famous for wearing his flip flops," says Paul. The entire project was inspired by their parents’ philosophy, their globetrotting childhoods and what happened to them in Sri Lanka. Their parents had previously worked in the fashion industry before quitting their jobs and focusing on humanitarian projects. Thus, Gandys is a very fitting tribute to their lives. Gandys sells flip-flops and donates 10 percent of the profits from every pair sold to orphans around the globe. In conjunction with Gandys, the Forkans also founded Orphans for Orphans, a charitable organization dedicated to helping orphans. They say they can make a profit and do good at the same time: they give 10% of their profit to charity, and have set up their own foundation through which they've been able to open a children's home in Sri Lanka.
This year alone, Gandys has sold 250,000 pairs of flip flops, which is only expected to increase. In 2013, the business made around 1.2 million pounds ($1.8 million). With more profits, more orphans will receive assistance. Hence, it’s safe to say that the Forkan brothers are making their parents very proud.
The two brothers left the UK for India because _________.

A.the UK education system is not so good as that of India
B.their parents had humanitarian projects in India
C.the voluntary work in Goa attracted them
D.their parents expected them to grow through travelling

We can infer from the passage that _______.

A.the parents had great influence on the two brothers
B.the two brothers were left hopeless after the tsunami
C.their parents died soon after they settled in India
D.the two brothers had a troubled childhood

Why did the brothers name their sandals after Gandhi?

A.Because Gandhi wears and sells flip flops.
B.Because Gandhi always helps orphans.
C.Because Gandhi is influential in India.
D.Because Gandhi fits into their lives in India.

What can best describe the brothers?

A.Unlucky. B.Modest. C.Generous. D.Ambitious.

What’s the best title of the passage?

A.Orphans for Orphans
B.Making Parents Proud
C.Gandys: Making Money and Doing Good
D.Rise Up from Tragedy to Success
