While only about 200 astronauts have had the excitement of looking down at Earth and commanding systems on the International Space Station, actually thousands of everyday middleschool students have experienced by Middle School Students, or EarthKAM, a camera system.
EarthKAM is an educational activity and outreach(擴展)investigation that also results in remote Earth sensing and observation. Using the Internet, the students control a special digital camera fixed aboard the space station, enabling them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest from the unique advantage point of space.
While EarthKAM offers a powerful way for students to investigate Earth from the unique perspective of space, it is also inspiring the next generation of flight controllers for space programs—involving university students to control and operate the camera system and related activities from the ground.
In the interview, Brion Au, one of the investigation developers at NASA's Johnson Space Centre, said，“EarthKAM is a payload(有效載荷)by students, for students. They are in charge. This system provides a viewpoint that the astronauts have...it's just aweinspiring！”So far, students have captured more than 40,000 photos of the Earth from the space station as it orbited the Earth once every 90 minutes, traveling at 17,500 miles an hour. The team at EarthKAM posts these photographs online for the public and participating classrooms around the world to view.
Au explains that this education investigation is inspiring students to explore the world by examining Earth, while promoting social studies, art, geography, science, technology, and math, among other important lessons involving research and teamwork. EarthKAM was started by Dr. Sally Ride, originally flying on the shuttles. The camera is located in the window Observational Research Facility, also known as the WORF, one of many the station's research facilities.

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透鏡）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (發(fā)電機) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.
So keep dreaming and inventing. One day you might get it right.
【小題1】What can we learn about Adaptable glasses?
| A．They are very expensive. | B．The inventor is a student. |
| C．The glasses are fragile. | D．They don’t look very nice. |
| A．Adaptable glasses. | B．The wind-up radio. |
| C．The Dyson cleaner. | D．The Zapata fly-board. |
| A．helping people use cleaners more easily |
| B．making Dyson a rich businessman |
| C．keeping the house cleaner than before |
| D．taking the place of human cleaners |

We are fortunate to be living in a time when all people have the ability to access any knowledge they desire. This digital society that we live in affords us opportunities that our ancestor only dreamed of having. We should not take this privilege for granted.
In the not so distant past of the 1950s, people who wanted to research an idea, a product, or anything else, had to go to a library where they could look up information in books. Not all people had the same access to the books, and the information they contained. In America, if your skin was black, you could not use the same library that a person with white skin used. If a black skinned person was allowed access to a library, it most likely was stocked with outdated books that white skinned people had discarded.
In the digital society we live in today, the color of your skin does not determine the access you have to information. Technology has brought to us the powerful tools like the Internet where we can find information on almost every subject.
Access to the Internet has allowed us to research the things we are planning to purchase. We are capable of comparing prices on things like insurance, appliances, entertainment, clothing, and all other things. We also now have the ability to purchase items online without ever leaving our homes. We have been freed from the restrictions of store hours, and regional sales. A person in America can purchase a product from a person in Germany, without leaving home.
Because of the digital society we live in our children can learn about anything they are interested in. When they ask you what the dinosaurs ate, you can look it up, and tell them the answer. Because of this people will be smarter in the future, and technology will only improve.
【小題1】By “We should not take this privilege for granted”, the writer means that ______.
| A．we have special right to do anything |
| B．it is wrong to make use of the privilege |
| C．knowledge is important in the digital society |
| D．we should seize the chances the modern society offers |
| A．the Internet brings us a lot of convenience |
| B．people in modern society are mostly wealthy |
| C．we would like to stay at home every day |
| D．we can find anything we like in the world |
| A．people will be much clever than ever |
| B．what the dinosaurs ate seems strange to us |
| C．finding out what the dinosaurs looked like is easy |
| D．we can learn knowledge with the help of technology |
| A．critical | B．positive | C．neutral | D．negative |

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example. What will be the next?

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (尋求刺激) or imperative (沖動) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
【小題1】The research led by Sanbonmatsu indicates that people who multitask __________.
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．a(chǎn)re more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
| A．a(chǎn)ssessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．a(chǎn)nalyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
| A．limited power in calculation |
| B．interests in doing things differently |
| C．inability to concentrate on one task |
| D．impulsive desire to try new things |
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
“Humans constantly attribute(歸屬) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,” said Dr Kaminski.
“These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
【小題1】According to the passage, which of the following is TRUE?
| A．The researchers made the test on dogs in eighty-four countries. |
| B．Dogs always obey and don’t steal forbidden food. |
| C．Dogs may adapt their behavior in response to the changed circumstances. |
| D．The research is carried out to find out how dogs are influenced by light. |
| A．Dogs---Our Loyal Companions Understand Us Most. |
| B．Dogs Are Our Best Friends. |
| C．Dogs Can Understand Us In a Way, Researchers Say. |
| D．Dogs Have Certain Qualities and Emotions of Human Beings, Researchers Say. |
| A．Textbooks. | B．Advertisements. | C．Instructions. | D．Magazines. |
| A．a(chǎn)n argumentative writing | B．a(chǎn) feature story |
| C．a(chǎn) dog show review | D．a(chǎn) research result |

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
【小題1】What can we learn about Dr. Marcy from the passage?
| A．He is fond of watching Jupiter. |
| B．He is from a scientist family. |
| C．He dislikes working with Paul Butler. |
| D．He is interested in finding life in outer space. |
| A．The planet is not as protective as Jupiter. |
| B．The planet is close to star 55Cancri. |
| C．The planet proves to be a gas planet. |
| D．The planet is as large as Jupiter. |
| A．1995 | B．1985 | C．2002 | D．1981 |
| A．he has found the system similar to the solar system. |
| B．he has discovered an Earth-like planet there. |
| C．he has discovered a rocky planet there. |
| D．he has found signs of life in the system |
| A．they felt discouraged | B．they carried on with it |
| C．they failed in their attempt | D．they made some progress |

High-tech machines have made life easier for millions around the world. However, some people still prefer low-tech ways of doing things. Here’s an example of why this is happening. You can microwave a frozen hamburger in 60 seconds. However, it won’t taste as good as one you cook on the stove. And if you’re in that much of a hurry, you probably won’t take time to toast the bun. High-tech cooking saves time, but it doesn’t make for better-tasting meals.
Most people get their news from high-tech sources like television or the Internet. This has many advantages. For example, electronic news is more up to date than newspapers or magazines. It’s also more exciting to see live and videotaped news events than photographs. However, newspapers and magazines have some important advantages. They give more background and details. They also let you read the parts that are important to you and skip the rest.
Other high-tech timesavers have similar disadvantages. For examples, most people use the phone or e-mail to stay in touch with friends and family members who live in other places. But when you use the Internet or the phone, you don’t always think carefully about what you are saying, and sometimes you forget the important things you want to communicate. Similarly, when you word-process a homework assignment instead of handwriting it, you can check your spelling electronically and put in fancy headings. However, some students are so busy with the computer that they don’t pay enough attention to the actual words they are writing.
【小題1】Which of the following statements is TRUE according to the passage?
| A．The writer likes high-tech cooking. |
| B．Low-tech cooking produces better-tasting meals. |
| C．High-tech news programs always keep you reading what is important to you. |
| D．Handwritten homework is better than word-processed homework. |
| A．Better late than never. | B．Easy come, easy go. |
| C．Every coin has two sides. | D．Learn to walk before you run. |
| A．High-tech vs. low-tech |
| B．Advantages vs. disadvantages. |
| C．Newspapers and magazines vs. television and the Internet. |
| D．Word-processing vs. handwriting. |

Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri（MU） researchers are developing a nuclear energy source that is smaller, lighter and more efficient．
“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”
His new idea is not only in the battery’s size, but also in its semiconductor（半導(dǎo)體）．Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor．
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶體結(jié)構(gòu)） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”
Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery’s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair
【小題1】The text is most probably a ________．
| A．science news report | B．book review |
| C．newspaper ad | D．science fiction |
| A．get rid of the radioactive waste |
| B．test the power of nuclear batteries |
| C．decrease the size of nuclear batteries |
| D．reduce the damage to lattice structure |
| A．uses a solid semiconductor | B．will soon replace the present ones |
| C．could be extremely thin | D．has passed the final test |
| A．to show chemical batteries are widely applied |
| B．to introduce nuclear batteries can be safely used |
| C．to describe a nuclear-powered system |
| D．to introduce various energy sources |
