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.

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.
【小题1】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．Heat can also be collected from asphalt roads. |
| D．The Dutch engineer's system has been widely 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. |
| A．the system can do more than warming up the building |
| B．some pipes have to be re-arranged in winter |
| C．the exchangers will pick up heat from the street surface |
| D．less heat may be collected in winter than in summer |
| 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. |

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.

Life in space will certainly take some getting used to！But the space station has been designed to keep the astronauts as comfortable as possible—the modules(舱) are roomy，bright，and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday，crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals，and 8.5 hours sleeping.Here are some other fun facts about life aboard the station：
Food
Come mealtime，astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions，astronauts could eat only freezedried food that didn’t require any preparation.But the space station is equipped with water，microwave ovens，and refrigerators，allowing the folks on board to eat more “normal” types of food，including fruit，vegetables，and ice cream!
Sleep
Each crew member has a private room.With no gravity，they’ll need to tie themselves to their beds，or they will float away！That might sound like a strange way to sleep，but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it，but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up，sit down or walk in space，so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this，astronauts on the station will exercise on bikes，rowing machines，and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U．S.shuttle or Russian rockets.But once they’re safe inside the space station，crew members can wear regular clothing.Of course，a specially designed，pressurized space suit is required for space walks.It has to withstand(经受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble！Astronauts will use a freshwater hose(软管) to take showers，shampoo，and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space？With a special “air toilet” that uses flowing air instead of water to dispose of waste.
【小题1】The facts about life in space are all mentioned EXCEPT ________.
| A．clothing | B．entertainment |
| C．sleep | D．exercise |
| A．The temperature is quite different in different places in space. |
| B．Astronauts must wear special space suits all the time in space. |
| C．Astronauts can wear regular clothing for space walks now. |
| D．Astronauts wear pressurized space suits just to keep warm. |
| A．It can make astronauts feel relaxed in space. |
| B．It can help astronauts spend their spare time happily. |
| C．Astronauts’ lives are more important in space than on earth. |
| D．It can prevent astronauts from causing muscle and bone loss. |
| A．Astronauts could eat apples in space in the past. |
| B．Astronauts eat only fruit，vegetables and ice cream now. |

Across the United States, universities and colleges have been looking to become more sustainable (可持续发展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.
At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.
All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building would. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”
【小题1】We can learn from the text that the EcoDorm in the US .
| A．offers students the chances to have a natural living at college |
| B．was firstly built by two college students |
| C．was designed for saving building materials |
| D．is only applicable in few schools |
| A．where the EcoDorm was built |
| B．when the EcoDorm got its name |
| C．what the EcoDorm is made of |
| D．how the concept of EcoDorm started |
| A．It helps students to enjoy life at college. |
| B．It saves a lot of money and energy for the college. |
| C．It makes students study harder. |
| D．It brings new energy to the college. |
| A．A long-term development calls for students’ efforts. |
| B．Students’ ideas should be encouraged at college. |
| C．Green living is a new trend at American colleges. |
| D．Students can learn to protect the environment through practice. |

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
【小题1】European researchers are conducting hibernation experiments to ________.
| A．ensure astronauts to get a complete sleep |
| B．find the secret of some creatures |
| C．make preparations for the journey to Jupiter’s moon Callisto |
| D．know if man can sleep for years |
| A．Science fiction is people’s imagination. |
| B．Science fiction is imaginative, but it can be realized. |
| C．Things seem impossible may come true. |
| D．Things described in science fiction are sure to become true. |
| A．putting living cells into a sleep-like state is full of failure |
| B．Biggiogera is confident with the experiment |
| C．human’s hibernation needs no energy |
| D．medical research is the key to space flight hibernation system |
| A．Six humans to fly to Callisto |
| B．Human hibernation improves health |
| C．Space travel attracts people |

It's going to be a chaotic(混乱的)day. How do I know? It’s Monday. OK, joking. But, I do predict that today will be filled with the normal last-minute tasks, fire drills, and unforeseen events. So, how do you keep yourself from being swept away in the stream of chaos? How do you remain calm while others are rushing and panicking? There's a problem… Panic! When things don't go as planned, how do you react? Are you the calm one who works to fix things? Or the one running around like Chicken Little screaming that the sky falling? Getting upset or alarmed can seem like natural reactions to a problem.
Here are a few tips to kelp you remain calm in the face of the storm:
? Don't Panic You are better able to find a solution if you aren't panicking. If you can keep your head when others are losing theirs, you will be able to make a dear decision in the chaos.
? There Aren't Many True Emergenaes My time as a Naval Officer taught me about true emergencies. In the military, when there is a problem, people can get hurt or die. This is not usually the case when the office copier or email server goes down. Keep things in perspective. There are very few true emergencies in life.
? Avoid the "Fight or Flight" When you are stressed, your body will want to go into "fight or flight." Your body was designed to keep you safe from danger, but its natural reflexes aren't always the best solution against a project gone away. Keep your emotions in check and ensure that your physical reflexes don’t make bad decisions for you.
? Head Into The Problem While everyone else is running away, true leaders walk into a problem. Sticking your head in the sand only makes things worse. Instead of trying to ignore the situition, get to the heart of the issue as soon as possible. Only then can you address it
How Will You React? When you find yourself ready to lose it, take a step back. Ask, "In this truly an emergcncy?" Keep your head when others are losing theirs. And you'll find that you are that much closer to a solution.
【小题1】The author writes the first paragraph in order to______.
| A．describe a chaotic day | B．advocate a way of life | C．introduce a topic | D．make a joke |
| A．low your head | B．keep your head | C．shake your head | D．stick your head |

October 15th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donors（捐赠者） will give 150,000 bars of soap to schools in Ethiopia.
Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children’s Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub（揉搓） it into all areas, including under the fingernails（指甲）. Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.
The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect（感染）themselves by touching their eyes, noses or mouths. Then they can infect others.
【小题1】What’s the best title for this passage?
| A．Say no to washing hands in the wrong way. |
| B．Find out why washing hands carefully is so important. |
| C．Hand washing: so important----it gets a day of its own. |
| D．Want to live a longer life?-wash your hands. |
| A．to dry your hands | B．to wash away the soap |
| C．to rub your hands carefully | D．to clean your fingers |
| A．how to wash your hands correctly |
| B．why washing hand with soap is so important |
| C．the dangers of washing hands without soap |
| D．when we should especially wash our hands with soap |
| A．Medical care | B．Public service | C．Health report | D．Advertisement |

Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.It also helps keep the soil from getting dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds，from growing.
Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.
It is easy to find organic mulch materials.Cutup leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.
The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil. As a result，mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.
