Kids at the Interlake School Division were the first Canadian students to take part in a program to send experiments to the International Space Station.(ISS).
Jordan Schott and three other sixth grade students came up with the idea to test royal jelly(蜂王漿) in space . Their experiment came very close to be tested on the space station. “We were seeing if we could send it to space, and if it would lose its nutritional value” faster and or slower, ”said Schott. Schott is one of the 18 students in the Space Knights Club at Woodlands Elementary School, part of the Interlake School Division. Over 450 students from the Division took part in the program.
“I thought we were just students and we couldn’t do much in the way of that. It’s a way to communicate with people up there ,” said Braeden Clark, a seventh grade student who is also in the club.
The astronauts shared what they learned with their school with a full day of activities all about science and space.
Teacher Maria Nickel is the organizer of the club. She said the day was great for students to learn what they could do. “Space is one of those great things that get kids excited, but it also gives them the chance to do so much. They can be an astronaut; they can be an engineer, ”She said.
The day was held in honour of Chris Hadfield, a Canadian astronaut now in the Internal Space Station. “It gives kids someone more to look up to. Here’s a real hero to look up to who’s doing it all, doing it through education,” said Nickel.
Jordan Schott thinks it’s really cool. “To me it seems so cool how people can go up to space, and science is something I’ve always liked,” She said. Schott says she wants to follow in the footsteps of Hadfield and be an astronaut when she gets older.
One of the winning experiments in the competition was produced by students from Argyle, Manitoba. It will travel to the space station in the fall of 2013.

Europe’s deadly outbreak of a rare form of E. coli bacteria (大腸桿菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(腸) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
【小題1】What is the main topic of the text?
| A．Bacteria. | B．A high-tech scanner. | C．A camera | D．Food safety. |
| A．broke out all over the world | B．comes from soil or animal waste |
| C．is extremely harmful to health | D．does not cause illness |
| A．can help to sort out different fruits |
| B．make the produce appeal to shoppers |
| C．can only capture images of the whole apple |
| D．can identify the presence of contaminants |
| A．The scanner needs to be improved. |
| B．The scanner will be available in the next several years. |
| C．Moon Kim is unwilling to develop the scanner. |
| D．The scanner is connected to a sorting machine. |

400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(蘚類植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(莖). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔蘚類植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(瀕絕生物保護區(qū)), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（論文集）of the National Academy of Sciences.
【小題1】Dr La Farge’s research is of great importance to ________.
| A．knowing what the plants during the Little Ice Age were like |
| B．understanding how ecosystems recover from glaciers. |
| C．regrowing many species that have been destroyed before. |
| D．figuring out the effects of melting ice caps on moss. |
| A．surprised me | B．greatly frightened me |
| C．put my doubt out of my mind | D．was exactly what I had in my mind |
| A．lives better in small groups |
| B．is very active in hot weather |
| C．is strong enough to survive coldness |
| D．is chosen from Canadian refugia |
| A．Bryophyte ecology is greatly affected by climate change. |
| B．400-year-old moss’s survival is a mystery to solve. |
| C．Moss in ancient times was discovered in Canada. |
| D．400-year-old plants were brought back to life. |

Monkeys , face to face
DISCOVER magazine once reported on a curious event in the woods : a group of monkeys applied mud (泥) to their faces in order to keep away insects , but when they were done they seemed to have lost their ability to recognize each other ---two monkeys that were supposed to be friends even started fighting.
“Faces are really important to how monkeys and apes (猿)can tell one another apart,” explained Michael Alfaro, a biologist at University of California, Los Angeles (UCLA), to the New York -based International Science Times . This is quite different from many other animals , which depend heavily on smells.
Since faces play such a crucial part in the social lives of monkeys , could this explain why certain monkey species have such colorful faces while others have simpler, plainer ones ?
To test this theory , a group of researchers from UCLA studied 139 monkey species , mainly from Asia and Africa, and analyzed hundreds of headshot (頭像）photos of those monkeys from their databases.
It was found that species that live in larger groups have faces with more complex color patterns than those that live in smaller groups. According to Live Science, researchers believe that this is nature’s way of making it easier for monkeys to recognize each other since those living in larger groups have to distinguish between a greater number of faces.
This is actually not that hard to understand . Just imagine if there were 10 people standing in front of you, all wearing white clothes. It would be much more difficult to tell them apart than if they wore clothes with colorful patterns. However, if there were only two people that you had to identify, a lack of color wouldn’t be much of a problem.
Apart from the need to recognize group members , researchers found that geography and environment also affect monkeys’ facial colors. Species that live closer to the equator in thick, humid (潮濕的）forests were found to have darker faces than those who live in dry areas further away from the equator. This is because darker faces help camouflage (偽裝）the monkeys in the woods so that they go unnoticed by predators (捕食者）.
【小題1】We can learn from the article that monkeys mainly recognize each other by their __.
| A．Smells | B．Facial appearances | C．body shapes | D．Voices |
| A．Larger monkeys have more complex face color patterns. |
| B．Monkeys with colorful face patterns usually take higher social positions within groups. |
| C．Monkeys living in smaller groups usually have simpler, plainer face patterns. |
| D．Colorful face patterns keep monkeys safe from predators. |
| A．The social lives of monkeys. |
| B．How monkeys tell each other apart. |
| C．A comparison between the face patterns of monkeys and those of human beings. |
| D．The different factors that determine monkeys’ face patterns. |

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.
All children soon learn what “Don't touch!”means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!
Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show.
If you want to see better, reach out and touch. Then you will really see!
【小題1】By touching things, .
| A．you will have a strange feeling |

In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate (引起，導(dǎo)致) the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances hundreds--- even thousands--- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is converted to energy in the form of strong winds. As the heat increases, the young hurricane begins to swirl in a counter-clockwise (逆時針方向) motion.
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea, the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
【小題1】When is an ordinary tropical storm called a hurricane?
| A．When it begins in the Atlantic and Caribbean seas. |
| B．When it hits he coastline. |
| C．When it is more than 75 mils wide. |
| D．When its winds reach 75 miles per hour. |
| A．The destructive effects of water. |
| B．The heat they release. |
| C．That they last about nine days on the average. |
| D．Their strong winds. |
| A．the low-pressure area in the center of the storm |
| B．the force of waves of water. |
| C．the trade winds |
| D．the increasing heat |
| A．heavy rainfall |
| B．dangerous waves |

Astronomers have captured(捕獲) the first direct image of a planet being born.
Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
Planets can change orbits(軌道) after forming, so it’s difficult to answer such questions by studying older planets.
“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮強過) them. Kraus and Ireland used two techniques to overcome this problem.[來源:學(xué)+科+網(wǎng)]
One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
【小題1】The research on younger planets helps scientists _____________.
| A．study why planets change orbits after forming |
| B．understand how planets move around their stars |
| C．a(chǎn)nswer questions about the age of stars and planets |
| D．know the relationship between planets and their stars |
| A．Their stars are brighter than them.. | B．They are very far from the earth. |
| C．They are generally too small. | D．They rarely form. |
| A．have been working in the same university |
| B．observed the planet on a volcano in Hawaii |
| C．used two new methods in the observation |
| D．cut holes in the mirrors when observing |
| A．Youngest planet seen as it’s forming. |
| B．Planet 450 light years away discovered. |
| C．World’s first direct image of a planet taken. |

LG Electronics, the world’s fourth largest cell phone producer, has added another feature to the mobile phone-reading books for the visually impaired(弱視的). The company started marketing the model, the LF1300 on Sep.18. No other people but the blind and visually-impaired with a certificate(證書) can buy the talking phone at sales shops of LG Electronics.
“The LF1300 is the world’s first mobile phone that is capable of reading books for the print-disabled, who otherwise could not enjoy them. This is not about making money but about continuing to put froth efforts to reduce the digital difference for the disabled,” LG Vice President said.
Its users can download about 300 audio (聲音的) books from the Internet site of LG Sangam Library to their phones for free in two ways. One is to access the digital library’s Website on a computer designed for the blind to get the audio books and transfer them to cell phones. The other is to download the digital books directly with cell phones through the wireless net work by touching a hot key on the LF1300 phone. www.zxxk.com
On top of its unique feature of reading books, the LF1300 is no worse than the popular top-line phones in both outlooks and functionalities(功能性). The phone is armed with an MP3 player and a Bluetooth headset, enabling users to listen to the music or talk without a cord. The user interface（界面) of the LF1300 is also designed for the blind, enabling phone users to control it through a voice guidance system.
However, because the phone’s internal memory of 17MB is small even for a single audio book file, which takes up 80MB on average, a high-volume external memory is a must for the talking book services.
【小題1】 are allowed to buy the talking phone.
| A．Disabled people with a certificate |
