Imagine living in a city made of glass. No, this isn’t a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs.
The reef you’d be looking at is made up of glass sponges(海绵). But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old.
When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms.
Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane(甲烷) gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges.
“It’s a new ecosystem we know nothing about,” said Dr. Johnson.
The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a “kindergarten” by scientists.
Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home.
The Washington coast isn’t the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were stunned to see it.

Below is a selection from a popular science book.
If blood is red, why are veins (静脉) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy (眩晕的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals （哺乳动物）have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
【小题1】What is the color of blood in a vein near the surface of the skin?
| A．Blue | B．Light yellow |
| C．Red | D．Dark reddish purple |
| A．Because their spine is in active use. |
| B．Because they are more easily affected by gravity. |
| C．Because they keep growing backwards. |
| D．Because their spine becomes more bent. |
| A．In the long run, our brain probably works harder than our heart |
| B．When our brain senses the spinning, we will feel dizzy. |
| C．The brains of the other mammals are as complex as those of humans. |
| D．Our feelings and emotions come from the most developed area in our brain. |

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino （厄尔尼诺）. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韦）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication（出版物）Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
【小题1】El Nino is known as ___.
| A．the changing of the weather in southern Africa |
| B．the warming of waters in the Pacific Ocean |
| C．the weather which brings drought（旱灾）to Africa |
| D．the weather phenomenon（现象）that brings heavy rains to Africa |
| A．they can provide a kind of early warning to the place that will suffer from drought |
| B．they can tell why Zimbabwe has little or no rain |
| C．they can do some research work in this field. |
| D．they can put all this information into their computers. |
| A．Scientists come to understand how El Nino appears. |
| B．Three scientists from the USA work on this subject. |
| C．Southern Africa suffered a serious drought and many people died from hunger. |
| D．El Nino has something to do with Zimbabwe’s poor crops. |
| A．The computer is used in this research work. |
| B．Scientists know when an El Nino appears by means of the computer program. |
| C．The scientists published their results of the research work. |
| D．Nature is the name of the article written recently by the scientists. |
| A．Appearance of El Nino is Predictable（可预测的） |
| B．Drought in Zimbabwe |
| C．Early Warning System |
| D．Weather in Africa |

It’s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write ... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John’s house, and he is a telecommuter — he works at home, communicating with the workplace through the Internet.
Like John, millions of people — and their employers — are finding that telecommuting is a great way to work. Telecommuters can follow their own timetables. They work in the comfort of homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems.
Jobs that are suited to telecommuting include writing, design work, computer programming and accounting. If a job is related to working with information, a telecommuter can probably do it.
【小题1】From the passage we can learn that John does his job .
| A．by telephon | B．through the Internet |
| C．in his office | D．away from home |
| A．work for several employers | B．enjoy a lot of traveling |
| C．get along well with other workers | D．work on your own schedule |
| A．their employers can save money |
| B．their employers will give them a higher pay |
| C．they can get more work experience |
| D．they will have a longer paid holiday |

The State Council declared Wednesday it would restart China's nuclear power program, ending the hiatus（中断）in nuclear construction since Japan's Fukushima nuclear disaster last year.
China has been the most courageous country in building nuclear power, with the largest number of plants currently under construction. Nuclear power is facing a tough time in developed countries. The Japanese public is demanding the closure of all the country's nuclear power plants. China is at the forefront of nuclear power development. But it has been forced into this position.
Rapid economic development coupled with improvements in people's life both demand more electricity. It is impossible to exploit fossil resources forever as the supply of coal, oil and natural gas is limited. China has no choice but to develop nuclear power.
China must be the safest user of nuclear power. It should become a leading country in developing nuclear power technologies and increasing the world's knowledge of nuclear power.
It needs to do at least two things. First, it needs to promote safety in nuclear power plants, based on the technologies of the West. The former Soviet Union, the US and Japan all had severe nuclear accidents, proving there are risks. China should try to remove these risks.
Second, China should establish effective communication mechanisms（机制）between the government, power plants and the public. It's wrong to think the government can control every aspect of nuclear power plant construction.
The opposition to nuclear power program in developed countries has prevented them from building new plants, but they already have many. These governments are reluctant to close these plants despite strong opposition, because they cannot find better substitutes.
Nuclear power only occupies 1.8 percent of China's current electricity grid（输电网）, much lower than the proportion in many developed countries. China's nuclear power plan should introduce the advantages of the technologies of other countries and also be creative in providing security. Its space technology is not the most advanced, but its launch safety measures have proven to be among the best.
China's high-profile high-speed railway development has drawn a lot of controversy, as will the active attitude towards developing nuclear power. But China cannot just copy what the developed countries have done. The development of nuclear power must be unique to China and it must be a ground-breaking success. But now, the real test lies ahead.
【小题1】In the third paragraph the writer focuses on ______.
| A．the reason why China is to develop nuclear power |
| B．the difficulty China has in developing nuclear power |
| C．the measures China will take to develop nuclear power |
| D．the benefits China will have by developing nuclear power |
| A．Supportive. | B．Opposed. | C．Indifferent. | D．Objective. |
| A．copy exactly what the developed countries have done |
| B．depend entirely on domestic scientists and technologies |
| C．avoid people’s involvement in nuclear power plant construction |
| D．do everything in its power to guarantee safety in nuclear power plants |
| A．It will be unique but can hardly pass too many tests. |
| B．It will be full of controversy but carried out firmly. |
| C．It will be on a smooth way to a ground-breaking success. |
| D．It will receive much opposition from developed countries. |

As most university students are packing their bags，boarding trains or flying home for the Spring Festival，some will stay behind to spend the holiday on campus．
Zhou Yunyun，22，a senior finance major at Jilin University，has decided that instead of traveling to Hainan province，he will kill the time by playing computer games with his online friends．
“I'm used to chatting and playing with them every day．It’s just fun to make friends this way，”he said．“When I returned home in past years，my relatives always asked me a lot of questions about my plans after graduation．They had high expectations of me，which made me feel stressed，” said Zhou．
The campus，usually lively，will probably turn into a death town，with most restaurants，shops and student centers closed during the break．But there are also a few advantages，according to Jia Debao，2 1，a junior majoring in administration at China Agricultural University．“I might feel a bit lonely，but at least I can stay away from my parents’ complaining and enjoy the peaceful and quiet stay，” he said．“More importantly，I can enjoy the high speed of the Internet，I can always find empty seats in classrooms，and I don’t have to wait to use the bathroorm” But education experts recommend students who stay on campus to come up with more interactive plans．That’s because communication on the Internet can’t replace real life interpersonal relationships．
Society has promoted a kind of“couch potato" or close-in culture among some young people, according to Shi Tongyu, a researcher at the Chinese Academy of Social Sciences. He warned that this kind of lifestyle can damage students’ mental and physical development.
“When you constantly stare at a computer screen and type on your keyboard，you gradually lose the ability to socialize and survive normally，"said Shi．“A human’s most important task is to survive，which cannot be completed by staying at home all the time． Instead，it must be achieved through real life experience and communication．”

Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks ---- we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.
【小题1】Ray Birdwhistell believes that physical appearance ____.
| A．has little to do with culture |
| B．has much to do with culture |
| C．is ever changing |
| D．is different from place to place |
| A．before birth |
| B．as soon as one’s teeth are newly set |
| C．sometime after new teeth are set |
| D．around 15 years old |
| A．how much he or she laughs |
| B．how he or she raises his or her eyebrows |

It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not.
In Kenya, researchers have found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.
In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.
Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing.
The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.
【小题1】According to the passage, which of the following statements is true?
| A．Maasai people are a threat to elephants. |
| B．Kamba people raise elephants for farming. |
| C．Both Kamba and Maasai people are elephant hunters. |
| D．Both Kamba and Maasai people traditionally wear red clothing. |
| A．They attacked a man with the smell of new clothing. |
| B．They needed time to relax when smelling something unfamiliar. |
| C．They became anxious when they smelled Kamba-scented clothing. |
| D．They were frightened and ran away when they smelled their enemies. |
| A．Elephants attack people who wear red clothing. |
| B．Elephants use sight and smell to detect danger. |
| C．Scientists are now able to control elephants’ emotions. |
| D．Some Kenyan tribes understand elephants’ emotions very well. |
| A．Elephants learn from their experiences. |
| B．Elephants have sharper sense of smell than sight. |
| C．Elephants are more intelligent than other animals. |
| D．Elephants tend to attack rather than escape when in danger. |

The way we get about has a deep influence on the way we live－affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演员) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.
