This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕櫚) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障礙)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻類(lèi)）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
小題1:．Why does Virgin Airlines try to replace normal fuel with biofuel?
A．To cut down the flight cost of the company.
B．To remove some hurdles for the biofuel to work.
C．To reduce CO2 emissions from airplanes.
D．To test plane engines on biofuel.
小題2:．Which is NOT true for a full biofuel switch of airplanes?
A Biofuel cannot run for long flights.                  
B．Biofuel cannot work at high altitudes.
C．Man has not enough land to grow extra crops for biofuel. 
D．It’s not easy for sewage treatment plants to manufacture biofuel.
小題3:．One of the hurdles to be overcome for a full biofuel switch is to          .
A．a(chǎn)lter the engine for airplanes
B．make biofuel burn consistently
C．open more land to grow more crops
D．develop sewage treatment plants
小題4:．We can infer from the last paragraph that          .
A．there is a long way to go for a complete switch to alternative fuel
B．it won’t be long before alternative fuel comes into use
C．a(chǎn)irlines, oil companies and airplane manufacturers are reliable
D．a(chǎn)lternative fuel has a bright future

For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall．Soon, that will change．Electronic commerce （trade） is growing fast and will soon bring people more choices．There will, however, be a cost: protecting the consumer from being cheated will be harder．Many governments therefore want to apply street regulations to the electronic world．But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation．
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything for the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty．But governments cannot enforce national laws on businesses whose only presence is on the screen．Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund for a clothes purchase．
One answer is for government to cooperate more: to recognize each other’s  rules．But that requires years of work and volumes of detailed rules．And plenty of countries have rules too fanciful for sober countries to accept．There is, however, another choice．Let the electronic businesses do the regulation themselves．They do, after all, have a self-interest in doing so．
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset．Governments, too, may compete to be trusted．For instance, customers ordering medicines on-line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead．
Customers will still need to use their judgment．But precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort．And the new technology will also make it easier for them to complain when a company lets them down．In this way, at least, the advent of cyberspace may argue for fewer consumer protection laws, not more．
小題1:According to the author, what will be the best policy for electronic commerce?
A．Self-regulation by the business．B．Strict consumer protection laws．
C．Close international cooperation．D．Government protection．
小題2:In case an electronic shopper bought faulty goods from a foreign country, what could he do?
A．Refuse to pay for the purchase．B．Go to the seller and ask for a refund．
C．Appeal to consumer protection law．D．Complain about it on the Internet．
小題3:In the author’s view, businesses would place a high emphasis on honest dealing because in the electronic world _________________________________．
A．international cooperation would be much more frequent
B．consumers could easily seek government protection
C．a(chǎn) good reputation is a great advantage in competition
D．it would be easy for consumers to complain
小題4:We can infer from the passage that in licensing new drugs the FDA in the United States is ____________________．
A．very quickB．very cautiousC．very slowD．rather careless
小題5:If a customer buys something that does not meet his expectation, what is the advantage of dealing through electronic commerce over the present normal one?
A．It will be easier for him to return the goods he is not satisfied with．
B．It will be easier for him to attain the refund from the seller．
C．It will be easier for him to get his complaints heard by other consumers．
D．It will be easier for him to complain about this to the government．

Little Mark is only 6, but he has an IQ of 200, a genius among geniuses. But his intelligence comes at a cost. His parents must keep him intellectually simulated（啟發(fā)）while making sure he is like any other little boy.
Mark has been attracted by the way how the world works since he was a baby. When he was 3, Mark was reading fluently, mostly self-taught. His parents haven't been able to keep him away from books since.
"I tried many times to stop him reading. We worry about his crazy fond of reading because he constantly wants to read every-thing whatever it is.”
A psychologist at the Centre for gifted children tested Mark and gave him an IQ of 200. The average child of Mark's age has an IQ of 100. At 200, Mark is a genius-even compared with other child geniuses.
"With children like Mark you can tell that's a bright child as soon as they walk in. They just have this sort of intensity, and maybe they're not so good at communicating with people," the psychologist said. "He will never fit perfectly into a class where he's with children of his age.”But Mark's mother worries about the "socially isolated" labels. "Nobody wants their child to grow up with that image. I want him to communicate with others freely, but not to be frustrated academically, so it's really hard to find a balance," she says.
Helen Dudeney from the Talented and Gifted Children Association says Mark is one in a million with such a high IQ. She points out that geniuses are still rare and difficult for the public education system to handle. "The lack of coping comes because teachers aren't trained in teaching gifted children," says Dudeney.
Helen believes it's also extremely important for them to be recognized and supported in their talents. Mark's parents are trying to figure out how best to help Mark. At the moment, there are few options. Mark finds first year work boring and simple, but he must learn to complete the work. His mother says, "We just want to be happy. Just to have a happy childhood and want to go to school every day.”
小題1:By saying "But his intelligence comes at a cost. ",the author means that        
A．Mark must pay for his intelligence at a high price
B．Mark's intelligence brings him negative effects at the same time
C．Mark's intelligence results from his parents
D．Mark's parents make Mark clever at all costs
小題2:Which of the following is NOT true according to the passage?      
A．Mark's parents are very satisfied with his love for reading.
B．Mark began to teach himself reading at the age of 3.
C．Many child geniuses are not good at communicating with others.
D．It is hard for parents to bring up a genius.
小題3:If there are 6. 6 billion people in the world, the number of geniuses with an IQ of 200 will be
________．
A．a(chǎn)bout 4,400B．a(chǎn)bout 5,500C．a(chǎn)bout 6,600D．a(chǎn)bout 7,700
小題4:What would be the best title for the passage?        
A．A genius' craziness for books
B．The life of the genius' parents
C．The burden of being gifted
D．The characteristics of Mark

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(無(wú)意識(shí)的,不自覺(jué)的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
小題1:What’s the purpose of the description of how bad you may feel when you’re woken up in the morning?
A．To explain why humans yawn.
B．To explain how humans start yawning.
C．To lead into the topic of yawning.
D．To complain about being woken up by the clock.
小題2:Which is not among the possible reasons for yawning mentioned in the passage?
A．A way to show that you feel hot.
B．A way to get rid of carbon dioxide.
C．A way to cool off your brain.
D．A way to communicate.
小題3:In which situation are you likely to yawn?
A．When you feel frustrated.
B．The weather is hot.
C．Someone else yawns near you.
D．When you breathe in a lot of carbon dioxide.
小題4:What can we learn from the passage?
A．The real reason why humans and most animals yawn.
B．Hiccups are an involuntary human action similar to yawns.
C．The more an action can be studied, the easier it is to research.
D．Finding out why humans yawn should be easier than sending people into space.

No satisfactory way exists to explain how to form a good idea. You think about a problem until you're tired, forget it, maybe sleep on it, and then flash! When you aren't thinking about it, suddenly the answer arrives as a gift from the gods.
Of course, all ideas don't occur like that but so many do, particularly the most important ones. They burst into the mind, glowing with the heat of creation. How they do it is a mystery but they must come from somewhere. Let's assume they come from the "unconscious." This is reasonable, for psychologists use this term to describe mental processes which are unknown to the individual. Creative thought depends on what was unknown becoming known.
All of us have experienced this sudden arrival of a new idea, but it is easiest to examine it in the great creative personalities, many of whom experienced it in an intensified form and have written it down in their life stories and letters. One can draw examples from genius in any field, from religion, philosophy, and literature to art and music, even in mathematics, science, and technical invention, although these are often thought to depend only on logic and experiment. All truly creative activities depend in some degree on these signals from the unconscious, and the more highly insightful the person is, the sharper and more dramatic the signals become.
A type of creative experience is illustrated by the dreams which came to Descartes at the age of twenty-three and determined his life path. Descartes had unsuccessfully searched for certainty, first in the world of books, and then in the world of men. Then in a dream on November 10, 1619, he made the significant discovery that he could only find certainty in his own thoughts, cogito ergo sum ("I think; therefore, I exist"). This dream filled him with intense religious enthusiasm.
Descartes' experience is representative of countless others in every field of culture. The unconscious is certainly the source of instinctive activity. But in creative thought the unconscious is responsible for the production of new organized forms from relatively disorganized elements.
小題1:Good ideas come from ________according to the writer.
A．the unconsciousB．creative activitiesC．dreamsD．logic and experiments
小題2:The underlined word “these” (paragraph 3) probably refers to __________.
A．philosophy, music, mathematics and science
B．religion, philosophy, literature, art and music
C．mathematics, science, and technical invention
D．both B and C
小題3:What point can we see in the example of Descartes ?
A．Dreams are the sources of instinctive activities.
B．Dreams sometimes contribute to important discoveries.
C．Geniuses have creative thoughts in their dreams.
D．Important discoveries are always made in dreams.
小題4: The best title for this passage may be __________.
A．The Unknown Becoming KnownB．The Role of Dreams
C．The Unconscious and Creative ActivitiesD．Birth of Bright Ideas

Have you heard of the saying, “If anything is worth doing, it is worth doing well”? The proverb is a piece of advice to make effects towards perfection in whichever job one does. It could be a small task like folding up your clothes, or a major one like organizing a business meeting in your later life.
Perfection just needs paying attention to details. If it is your job to dust the furniture at home, dust it so that not a single spot of dirt shows from any direction. If your task is to make the beds, make them so that not a single crease（皺紋）shows on the bed-covers.
There are only two ways to do a job: either sloppily, or well. If you choose the latter, you need to realize that any job that qualifies as (取得…的資格)“your” work deserves your best. Perfection is an attitude that can be developed with just a little effect. It is a habit that is helpful to a person in later life. Let us prove with an example: you may be asked to turn in an essay on, for example, wildlife, for a school project. Instead of writing carelessly a few facts that you already know, you could make the project more effective by looking up a reference books, encyclopedias（百科全書(shū)）or websites for additional information. You could then go over the finished essay for slips（疏漏）and errors, and provide pictures where necessary. If you make it a habit to put in extra effort in your school homework, will it not help you to handle more difficult projects at the college or university level?
As Michelangelo, the famous 16th century sculptor and painter, once put it: Trifles（瑣事）go to make perfection, and perfection is no trifle.
小題1:According to the passage, to achieve perfection is _______.
A．to realize the quality of the work
B．to pay attention to details of one’s work
C．to do as many jobs as possible
D．to form the habit of doing things ahead of time
小題2:The underlined word “sloppily” in paragraph 3 may mean _______
A．badlyB．patientlyC．carefullyD．slowly
小題3:What can be inferred from the third paragraph?
A．It is necessary to provide pictures for your essay.
B．Websites are the sources of information you want.
C．Perfection is a habit that promises a good future.
D．You should make much effort to develop perfection.
小題4:The purpose of writing this passage is to _______.
A．introduce the famous painter Michelangelo
B．a(chǎn)dvise us to do the things that are worth doing
C．explain to us the meaning of the perfection
D．expect us to give our best to our work

People should be warned against using mobile phones outdoors in stormy weather because they may“be struck by lightning”，according to doctors．
Three experts have described how a teenage girl was struck by lightning while using her phone in a large London park．The girl，aged 15，recovered，but a year later was still wheelchair-bound and found to be suffering complex physical and emotional problems.
The girl also had a perforate eardrum(打孔耳膜)on the side where she had been holding the mobile phone．She was having general recovery in Northwick Park Hospital，Middlesex．
Swinda Esprit，a senior house officer, said that while the brain and muscle damage was similar to that of many lightning victims—who can experience heart attacks on being struck—the ear problems were not．
She said that the damages were particularly relevant for people who might be involved in less serious lightning incidents，who might otherwise recover, but would never get their full hearing back if struck while on the phone．
“We were shocked by the damage，which is why we wanted to draw attention to it，”Dr Esprit said．“A year on and she still was suffering these difficult hearing．”
They added that three other cases had been reported in newspapers in China，South Korea，and Malaysia．In the Malaysian case，a sales executive was killed by lightning while talking on his phone during a thunderstorm near Kuala Lumpur．
“All these events resulted in death，”the doctors wrote．“This rare phenomenon is a public health issue，and education is necessary to stress the risk．”
The Australian Lightning Protection Standard recommends that metallic objects，including cordless or mobile phones，should not be carried outdoors during thunderstorms．However, “the United States National Weather Service says on its website that both are safe to use “because there is no direct path between you and the lightening”．
Paul Taylor, of “the Met Office'’，said the ear injuries were a consequence of mobile phones being metal，and not related to radio waves．
Mr. Taylor said that mobile phones should be treated as another piece of metal，similar to carrying coins or wearing rings，and people need to be warned against the possible danger．
小題1:What do we know about the teenage girl?
A．She was struck by lightning at schoo1．
B．She completely recovered from being struck．
C．She still suffered from mental problems．
D．She had to press her ear all day．
小題2:It can be inferred that damage done by lightening while using mobile phones      .
A．is more serious than that when one is not using a mobile phone
B．can be healed quickly except for heart attacks
C．is less serious because the victims can usually recover
D．is mainly in the brain and muscle of the victims
小題3:Why did doctors stress the risk about using phones outside in lightening?
A．Because more people are faced with it．
B．Because some deaths have been caused．
C．Because lightning is harmful for the brain．
D．Because a teenage girl got killed．
小題4:We can infer from the last three paragraphs that        .
A．both cordless and mobile phones are safe to use outside in lightning
B．there is no direct connection between lightning and ear injuries at all
C．opinions differ as to whether it is safe to use mobiles phones in lightning
D．ear injuries are the result of carrying coins or wearing rings in lightning
小題5:The purpose in writing this passage is       .
A．to draw attention to the risk of using mobile phones in lightening
B．to focus on various damages done to lightning victims
C．to tell us the news that a teenage girl was struck by lightning
D．to stress the danger of making phone calls in lightning
