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.

“iPhone 5”, the tallest thing to happen to iPhone since iPhone
We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (显示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快门). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!

I’ve always known my kids use digital communications gear (装置) a lot.But my cellphone bill last month really grabbed my attention.My son had come up to nearly 2,000 incoming text messages，and had sent nearly as many.Of course，he was out of school for the summer and communicating more with friends from a distance.Nevertheless，he found time to hold down a summer job and complete a college course in between all that typing with his thumb.
I was even more surprised to learn that my son is normal.“Teenagers with cellphones each send and receive 2,272 text messages a month on average，” Nielsen Mobile says.
Some experts regret that all that keyboard jabber is making our kids stupid，unable to read nonverbal cues such as facial expressions，gestures，posture and other silent signals of mood and attitude.Unlike phones，text messaging doesn’t even allow transmission of tone of voice or pauses，says Mark Bauerlein，author of a book called The Dumbest Generation：How the Digital Age Stupefies Young Americans and Jeopardizes Our Future.
Beyond that，though，I’m not sure I see as much harm as critics of this trend.I’ve posted before on how I initially tried to control my kids’ texting.But over time，I have seen my son suffer no apparent ill effects，and he gains a big benefit，of easy，continuing contact with others.
I don’t think texting make kids stupid.It may make them annoying，when they try to text and talk to you at the same time.And it may make them distracted，when buzzing text messages interrupt efforts to noodle out a math problem or finish reading for school.
But I don’t see texting harming teens’ability to communicate.My son is as accustomed to nonverbal cues as any older members of our family.I have found him more engaged and easier to communicate with from a great distance，because he is constantly available via text message and responds with faithfulness and speed.
【小题1】What does the underlined word “distracted” in the fifth paragraph mean?
| A．Confused. | B．Absentminded. |
| C．Comfortable. | D．Badtempered. |
| A．For Teens，Texting Instead of Talking |
| B．For Parents，Caring Much for Their Kids |
| C．Advantages and Disadvantages of Texting |
| D．The Effect of Communication |
| A．objective | B．opposed |
| C．supportive | D．doubtful |
| A．It is normal for a teen to send or receive 60 text messages a day. |
| B．Texting is a very popular way of communication among teens. |
| C．When texting，teens never mind talking with others. |
| D．The writer limited his son to send or receive text messages at first. |

Scientists discovered 163 new species in Southeast Asia’s Greater Mekong region last year，but all are at risk of extinction due to climate change，the WWF said in a report released Friday.
The newly discovered creatures include a birdeating frog with fangs (毒牙)，a bird that would rather walk than fly and a gecko (壁虎) whose alien appearance inspired the report’s title of “Close Encounters”，the conservation group said.
The report was released ahead of major UN talks on climate change in Bangkok next week，which are being held before a makeorbreak summit in Copenhagen this December.
“Some species will be able to adapt to climate change，and many will not，potentially resulting in massive extinction，” Stuart Chapman，director of the WWF Greater Mekong program，said in the report.“Rare and endangered species like those newly discovered are especially vulnerable (易受伤害的) because climate change will further shrink their already restricted habitats，” he said.
“The new discoveries in 2010 include 100 plants,28 fish,18 reptiles,14 amphibians,2 mammals and a bird，”the WWF report said.The area spans Cambodia，Laos，Myanmar，Thailand，Vietnam and China’s Yunnan Province.
“Among the new species is the birdeating fanged frog，which remains hidden in a protected area of Thailand despite the fact that scientists are studying there for 40 years，” the report said.
The tigerstriped pit viper was discovered accidentally on an island off the coast of Vietnam when a scientist was looking for a lizard and his son pointed out that his hand was on a rock right next to the snake’s fangs.“We caught the snake and the gecko and they both proved to be new species，” researcher Lee Grismer of La Sierra University in California was quoted as saying in the report.The leopard gecko，found on another Vietnamese island，has the coloring of a leopard and bizarre orange，catlike eyes and thin legs.
The Greater Mekong region has proved a rich area for scientists.The WWF said in December 2010 that it had found 1,068 new species there between 1997 and 2009.
【小题1】What is special about the newly discovered bird?
| A．It usually walks. |
| B．It likes walking and flying. |

| A．most of the newly discovered species can adapt to climate change |
| B．climate change can cause massive extinction of the newly discovered species |
| C．the newly discovered species are not so vulnerable to climate change |
| D．many species have already died out because of climate change |
| A．frightened | B．disappointed |
| C．excited | D．puzzled |
| A．The Greater Mekong region is a rich area for scientists. |
| B．Many rare species remain to be discovered in the Mekong region. |
| C．Scientists have discovered many new species in the Mekong region. |

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.
【小题1】What was the first piece of man-made space trash?
| A．A camera. | B．A tool kit. |
| C．A fuel tank. | D．A broken satellite. |
| A．It no longer served any useful purpose. |
| B．It was millions of miles away from the Earth. |
| C．It did not cause any problems. |
| D．It was regarded as similar to comets and stars. |
| A．It is huge, heavy machines. |
| B．It never changes position. |
| C．It floats slowly around the Earth. |
| D．It may cause problems for space shuttles. |

Many people believe that teaching children music makes them smarter, better able to learn new things. But the organizers of a new study say there's no scientific evidence that early musical training affects the intelligence of young people.
An estimated 80 percent of American adults think music lessons improve children's abilily to learn or their performance in school. They say that the satisfaction for learning to play a new song helps a child express creativity.
Researchers at Harvard University, however, have found that there's one thing musical training does not do. They say it does not make children more intelligent. Samuel Mehr is a graduate student at Harvard's School of Education. He said it is wrong to think that learning to play a musical instrument improves a child's intellectual development. He says the evidence comes from studies that measured the mental ability of two groups of 4-year-olds and their parents. One group attended music class, the other went to a class that places importance on the visual arts—arts that can be seen.
"The evidence there is 'no'. We found no evidence for any advantage on any of these tests for the kids participating in these music clases," said Mehr.Samuel Mehr says researchers have carried out many studies in an effort to learn whether musical training can make children smarter. He says the results have been mixed. He says only one study seems to show a small percentage increase in IQ, intellectual scores among students after one year of music lessons. He does not believe that IQ is a good measure of child's intelligence. He says researchers in his study compared how well children in the musical training group did on mental processing tasks or projects, then the results were compared to those of children who did not take lessons. There was no evidence that the musical training group did much better on the mental tasks than the other group.
The researchers comfirmed the results with a larger group of children and their parents.Mr Mehr says music lessons may not offer children a fast easy way to gain entry to the best schools later of their life. But he says the training is still important for cultural reasons. In his words, "We teach music because music is important for us."
【小题1】According to the new study, musical training______.
| A．makes children smarter |
| B．helps a child express creativity |
| C．does not make children more intelligent |
| D．improve children's ability to learn in school |
| A．the children who attended music class are smarter than those who attended arts class |
| B．IQ is a good measure of a child's intelligence |
| C．we needn't to teach children music |
| D．music training is still important for cultural reasons |
| A．conducted more than one research |
| B．interviewed many American adults |

Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil (零), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的).
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft.
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply (遵守) with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious , but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence (气流).
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.
【小题1】What is the overall reason for these air safety tips?
| A．What to do in the event of a crash. |
| B．How to avoid turbulence. |
| C．How to improve safety while you are flying. |
| D．How to avoid injury. |
| A．smaller planes | B．passengers | C．larger aircraft | D．safety records |
| A．anything the flight staff tell you to do |
| B．general safety advice |
| C．walking around the plane |
| D．pouring hot drinks |
| A．Larger planes have more safety checks and are safe in an accident. |
| B．Take-offs are safer on non-stop flights than landings. |
| C．Every aircraft is different, so the safety procedures may be different. |
| D．Seat belts should be worn to protect against turbulence. |
| A．The Safest Way to Travel | B．Air Safety Tips |
| C．Non-stop Routes | D．How to Fly a Plane |

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebra-fish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra-fish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebra-fish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra-fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
【小题1】The passage mainly tells us that ________.
| A．people can not change their skin color without any pain |
| B．the new discovery could lead to research into ways to change skin color safely |
| C．pop king Michael Jackson often changed his skin color as he liked |
| D．scientists have found out that people’s skin color is determined by the gene |
| A．nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment |
| B．Europeans and Africans have the same gene |
| C．the new discovery could help to find medical treatments for skin cancer |
| D．there are two kinds of genes |
| A．find the different genes of humans’ |
| B．prove the humans’ skin color is determined by the pigment gene |
| C．find out the reason why the Africans’ skin color is dark |
| D．find out the ways of changing people’s skin color |
| A．they are born light-skinned people |
| B．light-skinned Europeans have mutation in the gene for melanin production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
| A．neutral | B．negative | C．positive | D．unconcerned |

Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39yearold businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her sevenyearold daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”
The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.
The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.
【小题1】Which conclusion can we draw from the first paragraph?
| A．Hu Li is living in Beijing. |
| B．Hu Li traveled to Tianjin for business. |
| C．The haze is harmful to people. |
| D．The pollution is the worst in Beijing's history. |
| A．the way they traveled |
| B．the opinion about national air |
| C．the way they lived their life |
| D．the life style of internet |
| A．can lead to choke |
| B．can cause heart cancer |
| C．will damage children's development |
| D．will damage people's organ |
| A．Hu Li's attitudes to Beijing's haze |
| B．The damages of Beijing's haze |
| C．WHO suggests improving Beijing's air |
| D．What caused air pollution in Beijing |
