The first flights of the new airlines that will take tourists into space are ready to take off in 2012, and getting a seat on one is not all that different from booking a trip someplace on Earth. You can sign up on the website of, say, Virgin Galactic,the most wellknown of the new space tourism companies, or go to an approved travel agency and put down a large deposit. Soon you will be able to buy travel insurance,just as you can for any other vacation.
Until now,space tourism has been limited to the ultrawealthy. Just seven people have paid tens of millions of dollars each for a trip to the International Space Station aboard a Russian rocket.
But that could change this year, when Virgin Galactic intends to start offering flights just beyond the space barrier on a rocket ship it has built, featuring five minutes of weightlessness during a twoandahalfhour tour. At $ 200,000 a seat, this will open the final frontier to far more people.
At least two other specialty airlines have jumped in as well, taking reservations and deposits for future space flights.Allianz, the big insurer, will introduce an insurance product in 2012, lending space tourism the trappings of the regular travel industry.
“Just to be able to sell space travel as a regular part of your business, really, just how cool is that?” said Lynda Turley Garrett, president of Alpine Travel of Saratoga, Calif.,who is one of 58 accredited space agents for Virgin Galactic in the United States.
In five years,Ms.Garrett has sold three seats. But she expects that to change once passengers start going up and coming down to tell their friends. “By 2017,it'll be just like scheduling a flight to L.A.,” Ms.Garrett predicted.

Most people know that awkward feeling when you walk into an elevator with other people and try not to make eye contact(接觸). But a new research suggests it may be down to a subconscious power struggle being played out as you make your way up and down.
A study found that people decide where they stand based on a micro social status,established within seconds of entering the lift.
Rebekah Rousi.a(chǎn) Ph. D.student in cognitive(認(rèn)知)science,conducted an ethnographic(人種論)
Study of elevator behaviour in two of the tallest office buildings in Adelaide,Australia.As part of her research,she took a total of 30 lift rides in the two buildings,and discovered .There was an established order to where people tended to stand
In a blog she writes that more senior men seemed to direct themselves towards the back of the elevator She said:“In front of them were younger men,and in front of them were women of aII ages.”She also notice there
was a difference in where people directed their gaze(注視)half way through the ride.“Men watched the monitors,looked in the side mirrors(in one building)to see themseIves.And in the door mirrors(of the other building)to also watch others Women would watch the monitors and avoid eye contact with other users(unless in conversation)and the mirrors,”she writes.
She concluded it could be that people who are shyer stand toward the front,where they can’t see other passengers,whereas confident people stand in the back,where they have a view of everyone else.
【小題1】The passage is mainly about
A. elevator riding manners
B communication in the elevator
C. elevator riders’ standing positions
D. micro social status in the elevator
【小題2】The underlined word“it”in the first paragraph probably refers to“ ”
A.a(chǎn)n elevator | B.the new research | C.eye contact | D.social status |

Scientists who discovered a new way of generating electricity from water say they may have come across an alternative source of clean energy to rival wind and solar power.
The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter(濾水器)that contained thousands of narrow channels lined up side by side. “When we took a syringe(注射器)of water and squeezed it through the filter, we got enough power to light a light bulb,” said Larry Kostiuk of the University of Alberta in Canada. “The harder you push the syringe, the more electric current you get.”
The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions(陽離子)fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. “The last time someone came up with a way of generating electricity was Michael Faraday in 1839,” he said. “So this is the first new way of generating electricity in 160 years, which is why we are so excited about it.”
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. “You’d need to be sure it wouldn’t leak, and you’d need to make sure it wouldn’t freeze,” he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. “It could compete with wind and solar power,” he added.
【小題1】What does the passage mainly want to tell us about?
A.A kind of solar power discovered by scientists. |
B.A kind of new energy source found in tap water. |
C.The breakthrough to generate electricity 160 yeas ago. |
D.A kind of new battery invented without poisonous substances. |
A.rejects | B.identifies | C.a(chǎn)ttracts | D.rebels |
A.They were the first to find a new way to produce electricity. |
B.They could make an electric current to light a light bulb. |
C.Their discovery could be used to invent water batteries. |
D.Their discovery was made 160 years earlier than Faraday’s. |
A.They must be used to power mobile phones and calculators. |
B.They have some possible disadvantages like water leaking. |
C.They would be needed greatly at city water filtration sites. |
D.They would be better than wind and solar power. |

(2013·高考安徽卷,B)Using too much water or throwingrubbish into our rivers are clear ways that humans can put our water supply in danger,but we also affect our water supply in less obvious ways.You may wonder how paving(鋪砌) a road can lead to less useable fresh water.A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave,the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺).Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall,but in any case,good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference,too.In the United States,a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live,but there’s a lot we can do to lower the number.
You can take steps to save water in your home.To start with,use the same glass for your drinking water all day.Wash it only once a day.Run your dishwasher (洗碗機(jī))only when it is full.Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?
A.Using river water. |
B.Throwing batteries away. |
C.Paving parking lots. |
D.Throwing rubbish into lakes. |
A.All water shortages are due to human behavior. |
B.It takes a lot of effort to meet our water needs. |
C.There is much we can do to reduce family size. |
D.The average family in America makes proper use of water. |
A.show us how to fix leaks at home |
B.tell us how to run a dishwasher |
C.prove what drinking glass is best for us |
D.suggest what we do to save water at home |
A.Why paving roads reduces our water |
B.how much we depend on water to live |
C.why droughts occur more in dry climates |

BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips(微芯片) and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically(國內(nèi)的) developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.
【小題1】What’s the best title for this passage?
A.The Arrival of Chinese Supercomputers |
B.Homemade CPUs with a Long Way to Go |
C.The Supercomputers of Three Organizations in China |
D.Homemade CPUs on the Way for Local Supercomputers |
A.Dawning 6000 | B.Loongson microchips |

The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
【小題1】From the first two paragraphs we learn that________.
A.much of the world's water is available for use |
B.people in high rainfall countries feel lucky |
C.water can be easily carried through pipes across the world |
D.the costs of water redistribution should be considered |
A.The water stores in Texas have been reduced by 75%. |
B.Most industries in the world suffer from water shortages. |
C.The underground water in Saudi Arabia might run out in 50 years. |
D.Good management of water use resulted from the project in the Central Valley. |
A.Steps to improving water use management. |
B.Ways to reduce the costs of building dams. |
C.Measures to deal with worldwide water shortages. |

Monkeys prefer heavy metal to classical music, according to researchers at the University of Wisconsin whose findings are published this week in Biology Letters.
Scientists played a selection of music to a group of South American cotton-top monkeys but the only sound that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the beautiful sound of Master of Puppets by Metallica was played the monkeys calmed down.
"Monkeys interpret rising and falling sounds differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica," said Professor Charles Snowdon, from the University of Wisconsin-Madison.
Rather than making them excited or aggressive, the heavy metal tracks had a comforting effect. Dr Snowdon, who teamed up with National Symphony Orchestra musican David Teie, also played the monkeys music composed specifically for them. Although they enjoyed Metallica, they were much more interested in these pieces.
A melody(樂曲) based on the short calls of scared monkeys led to anxiety levels rapidly growing, researchers found, while one based on long calls the creatures make when they are happy had a calming effect.
Frans B.M. de Waal, a professor of psychology at Emory University who studies animals, said the findings appear to say more about how monkeys respond to the sounds they make than they do about music or the evolution of music.
Dr Snowdon no longer has a monkey colony to use in his research, but he said his co-author David Teie is exploring the concept of music for cats.
"If we understand how we can affect their emotional states through using musical sound and aspects of our speech, maybe those of us living with companion animals can have a better relationship with them, too," Snowdon said.
【小題1】The research mentioned in the passage is mainly about ______.
A.the change of music over time | B.a(chǎn)nimals’ response to music |
C.special music for animals | D.the origin of music |
A.looked anxious | B.became restless |
C.felt at ease | D.made long calls |
A.of Led Zeppelin | B.of Miles Davis |
C.of Metallica | D.specially composed for them |
A.build better ties between animals and humans |

A funny thing happened on the way to the communications revolution: we stopped talking to one another.
I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were walking and talking on a beautiful sunny day and... I became invisible, absent from the conversation. The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction(互動). With email and instant messaging over the internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.
As almost every contact we can imagine between human beings gets automated(自動化), the alienation index(疏遠(yuǎn)指數(shù)) goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.
I am not against modern technology. I own a cell phone, an ATM card, a voice mail system, and an email account. Giving them up isn't wise... they're a great help to us. It's some of their possible consequences that make me feel uneasy.
More and more. I find myself hiding behind email to do a job meant for conversation. Or being relieved that voice mail picked up because I didn't really have time to talk. The industry devoted to helping me keep in touch is making me lonelier ...or at least facilitating my antisocial instincts.
So I've put myself on technology restriction: no instant messaging with people who live near me, no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.
【小題1】Which of the following would be the best title of the passage?
A.The Advance of Communications Technology |
B.The Consequences of modern Technology |
C.The Story of Communications Revolution |
D.The Automation of Modern Communications |
A.the people sitting beside you have to go away to receive a phone call |
B.you can hardly get in touch with the people sitting beside you |
C.modern technology makes it hard for people to have a face-to-face talk |
D.people can now go to work without going to the office |
A.satisfying | B.encouraging | C.disappointing | D.embarrassing |
A.modern technology is bridging the people |
B.modern technology is separating the people |
C.modern technology is developing too fast |
