Baekeland and Hartmann report that the " short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 0r so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to regard their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
In general, these "short sleepers" appeared ambitious, active, energetic and cheerful. They stuck to their opinions, and were very sure about their job choices..They often held several jobs at once, or worked full-or part-time while going to school. And many of them had a strong urge to appear "normal" or " acceptable" to their friends and colleagues.
When asked to remember their dreams, the " short sleepers" did poorly. More than this, they seemed to prefer not remembering. Similarly, their usual way of dealing with psychological problems was not to admit that the problem existed, and then to keep busy in the hope that the trouble would go away.
The sleep patterns of the " short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic (躁狂者).
The "long sleepers" were quite different indeed. Baekeland and Hanmann report that these young men have been lengthy sleepers since childhood. They seemed to enjoy their sleep, protected it, and were quite concemed when sometimes they didn't have their desired 9 hours of nightly bed rest. They tended to remember their dreams much better than the " short sleepers". Many of the "long sleepers" were shy, anxious, quiet, nervous, passive, mildly depressed, and unsure of themselves ( particularly in social situations) . Several openly stated that sleep was an escape from their daily problems.
【小题1】From the passage, we can leam that .
| A．"short sleepers" need less sleep by nature |
| B．"long sleepers" sleep a longer period of time during the day |
| C．many "long sleepers" preserve their sleeping habit formed during their childhood |

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(藓类植物) 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(茎). 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(苔藓类植物) 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(濒绝生物保护区), 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（论文集）of the National Academy of Sciences.
【小题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. |

Astronomers have captured(捕获) 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(轨道) 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(光亮强过) them. Kraus and Ireland used two techniques to overcome this problem.[来源:学+科+网]
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.
【小题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．answer 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. |
| D．New technique helps discover young planets. |

Do you know mulch? 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 corn 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 good environment for earthworms and other helpful living things in the soil.
It is easy to find organic mulch materials. Cut-up leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from news- papers 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.
【小题1】The author tells us the following EXCEPT ______.
| A．what mulch is and its advantages |
| B．the best time to add mulch |
| C．the bad effects of mulch |
| D．what can be mulch on the soil surface |

| A．improve the condition of soil |
| B．improve the ability of the soil to hold water |
| C．provide a good environment for earthworms |
| D．improve the growth of roots and increase the movement of water through the soil |
| A．the best time to add mulch is in spring and summer |
| B．the best time to add mulch is after the coldest weather arrives |

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part—drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area, Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) consol. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,”if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the ear-size vehicles for a company called Sci-Autonics, “Even ants (蚂蚁) can do all these tasks effortlessly. It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately. Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
【小题1】DARPA organized the race in order to ______.
| A．raise money for producing more robotic vehicles |
| B．push the development of vehicle industry |
| C．train more people to drive in the desert |
| D．improve the vehicles for future wars |
| A．can do effortlessly whatever tasks living things can |
| B．can take part in a race across 142 miles with a time limit |
| C．can show off their ability to turn themselves upside down |
| D．can move from place to p1ace without being driven by human beings |
| A．about eight miles | B．six miles | C．almost two miles | D．about one mile |
| A．for a robotic vehicle to finish a 142-mile race without any difficulties |
| B．for a little child who has just learned to walk to reach the cookie on the table |
| C．for a robotic vehicle to deal with a simple problem that a little child can solve |

Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
【小题1】The study done by Rob Swihart and Jake Goheen is to ________ .
| A．find out the living conditions for squirrels |
| B．do something to get rid of squirrels |
| C．learn squirrels’ influence on black walnut trees |
| D．save the forests in the American state of Indiana |
| A．the way they gather the walnut |
| B．the place they store the walnuts |
| C．the time they have winter sleep |
| D．the place they have winter sleep |
| A．nuts above the ground will not develop into plants |
| B．red squirrels eat more nuts than gray squirrels |
| C．gray squirrels and red squirrels will have severe fights |
| D．seeds can be traps for other animals in the forest |
| A．Gray squirrels do more harm to the forest than red squirrels. |
| B．Red squirrels and gray squirrels have helped the spread of walnut trees. |
| C．The cleaning of forest land benefits red squirrels directly. |
| D．The black walnut is equally attractive to both gray and red squirrels. |

LG Electronics, the world’s fourth largest cell phone producer, has added another feature to the mobile phone-reading books for the visually impaired(弱视的). The company started marketing the model, the LF1300 on Sep.18. No other people but the blind and visually-impaired with a certificate(证书) 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 (声音的) 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.
【小题1】 are allowed to buy the talking phone.
| A．Disabled people with a certificate |

When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.
Underwater archaeology-the study of ships, aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment .Besides the Swedish ship wreck(残骸），underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world's knowledge of history, but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines(挖掘机）often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.
【小题1】What purpose does Paragraph 1 serve in the passage?
| A．To provide background information of the topic |
| B．To attract readers' attention to the topic |
| C．To use an example to support the topic |
| D．To offer basic knowledge of the topic |
| A．exploit water bodies | B．search for underwater life |
| C．study underwater artifacts | D．examine underwater environment |
| A．sea hunters have better diving equipment |
| B．their knowledge of world history is limited |
| C．dredging machines cause damage to the ports |
| D．sold artifacts can hardly be regained for research |
| A．To introduce a young branch of learning. |
| B．To discuss the scientists’ problems. |
| C．To explain people’s way of life in the past. |
| D．To describe the sunken ships. |
