Your Car Is Ready for Take-off
The flying car has been talked about for many years,but now it appears that the idea is about to become a reality.
An international company has built a two-seater plane that, at the touch of a button ,transforms into a car perfectly suitable for driving on public roads. It has been designed so that the wings fold up automatically; and it takes just 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋槳)spinning, it can take off from any airfield.
Flying cars are quicker than traditional ones for travelling from city to city,and they can run on ordinary fuel. Another big advantage is that they are cool ,like something you would see in an action film. At the moment 9 however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.
“The government and the authorities have never thought seriously about a flying car, says Alan Price ,the president of the company that has developed it. “I wanted a car that could fly and drive ,but it is difficult to find an organization prepared to insure the vehicle against accidents.
Nevertheless ? the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority the potential customers are older and some are retired。There have even been orders from some people who have no pilot's license.
The flying car will cost around $ 200.000. “For an airplane , thats a very reasonable price, but for a car, It's quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet. ”
This latest means of transport will not become a mass-market item in the near future,but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.
So the next time you are told to fasten your seat belt, it may be to prepare for take-off.
小題1:We know from the passage that the flying car______
A.has to run on special fuelB.will replace traditional planes
C.is popular with the richD.can shift between two forms
小題2:The flying car is presently forbidden to take off because______.
A.many people think driving it not very safe
B.it’s hard to decide whether it's a car or a plane
C.the government and the authorities don’t accept it
D.there are still some technical problems to be solved
小題3:We can learn from the passage that______.
A.few people will be able to afford a flying car
B.flying cars may share the market in the future
C.traffic jams will disappear because of flying cars
D.driving a flying car doesn’t require a pilot’s license

A long time ago, before human beings lived on the earth, little coral polyps(水螅)settled around tropical (熱帶的)coastlines and constructed corals. Over a long period they created lots of reefs. Yet, pollution, climate change and commercial fisheries are limiting the chance of future generations knowing or seeing many of the reefs and sea creatures that exist. Hence, take action to dive now and you can explore the underwater world.
Commercial underwater diving began in ancient Greece. Diving in general means that the whole body is completely in water. On that account there are lots of exciting and quite adventurous ways to dive, like shark cage diving, scuba diving(戴水肺潛水)and reef diving.
There are great coral reefs all over the world, but usually they are situated in warm, clear water such as the Pacific and the Indian Ocean, where they grow best. This is why there are no coral reefs on the west coast of South Africa. However, South Africa’s east coast offers much brightly coloured sea life.
In South Africa more than 100,000 dives a year are made just in coral reefs, which are one of the natural wonders of the world. To see the whole beauty of the reef the right diving gear(設備) is an essential requirement. This means a perfect fitting diving mask and fins, as well as a snorkel(呼吸管)and a friend. Diving alone is dangerous because there may be strong currents you are not aware of, and it’s a lot more fun to share the experience with someone. However, before you can explore the deeper sea, a certificated and checked scuba, a wetsuit and of course a license will be needed. Whether you choose the snorkel or the scuba to spot the colourful underwater world, try to touch as little as possible, be careful with the corals and don’t strike the fishes, because the complex ecosystem is very sensitive.
小題1:The following factors probably affect coral reefs EXCEPT ________.
A.sea creaturesB.pollutionC.fishingD.climate change
小題2:Which of the following is true according to the passage?
A.Human beings appeared before corals were created.
B.One needs a license to dive into the deeper sea.
C.Diving alone has many advantages.
D.The origin of diving is in modern Greece.
小題3:There are no coral reefs on the west coast of South Africa probably because of a lack of ________.
A.large waters and soft sand
B.warm currents and delicious food
C.friendly creatures and flat seabed
D.clear water and suitable temperature
小題4:The last paragraph mainly tells us ________.
A.diving alone under the sea is rather dangerous
B.some matters we need pay attention to when diving
C.South Africa is a popular place for diving
D.what we should wear when diving

For some reason, it takes constant reminders that we primates(靈長目)need nurturing.
In a recent study of 46 baby chimpanzee(黑猩猩)orphans, Kim Bard of the University of Portsmouth in England and her colleagues demonstrated that primate babies that have tight relationships with mother figures do much better on cognitive(認知)tests than babies who receive only food, shelter, and friendship with peers. But this is not breaking mews. In fact, it’s old news.
In the 1950s, Harry Harlow conducted a series of experiments with baby monkeys that showed, without doubt, that lack of love and comfort makes for a crazy monkey.
Harlow constructed a cage that included a wire monkey “mother” topped with a plastic face. In this wire he fixed Mom with a milk bottle. The cage also held another wire mother covered with terry cloth. The baby monkeys spent all their time with the cloth mother and only went to the wire mother to feed, demonstrating that a soft touch beat something to eat any day.
Harlow’s monkey work was important because, at the time, child care “experts” and everybody’s grandmother had a “no touch, no comfort” policy toward children. They advised parents not to respond to crying babies, felt babies should sleep alone to grow up independent, and for God’s sake put those kids down. But Harlow’s work changed all that. Mothers were soon permitted to have their newborns next to them in the hospital.
The current chimp research based on Harlow’s work shows that mother love not only makes for a psychologically well-adjusted child, but also makes for a smart kid. Bard and her colleagues evaluated the abilities of the chimps when they were 12 months old with standard human tests for children of that age, tests that ask little kids to imitate some action.
The highly raised chimps did better than the ones that were not loved, and what do you know, the well-raised chimps did even better than human kids on this small IQ test.
So we hear it once again. We are primates, social animals which need care and love. We need to be held and talked to and made to feel that at least one person wants to be with us all the time. And if we get that kind of connection, we are sure to be fine, even better than fine.
小題1:The study Kim Bard and his colleagues did ______.
A.included 46 baby and mother monkeys
B.was nothing new to people about the findings
C.showed that many chimpanzees lacked love when they were young
D.showed that many chimpanzees had good relationships with their mothers
小題2:Why was Harlow’s monkey work important?
A.Because the “no touch, no comfort” policy toward children was quite right.
B.Because parents were advised not to respond to babies’ crying.
C.Because Harlow’s work changed people’s former belief in child care.
D.Because mothers were not allowed to have their newborns next to them in the hospital.
小題3:Harlow built two “mothers” for baby monkeys to ______.
A.make them live comfortablyB.let them have more choices
C.give them more loveD.make a comparison
小題4:Which of the following is TURE according to the text?
A.Well-raised chimps always do even better than human kids.
B.A 12-month chimps is far cleverer than a child of that age.
C.The newborns were not allowed to be with their mothers in the past in the hospital.
D.Constantly touching the baby can make it feel safer.

About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need.
One reason for this is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result,many students go to class feeling like sixteen?year?old Danny.He is an active teen— except in the morning.“Getting up in the morning is pretty terrible.I’m just very out of it and tired.Through the first and second period I can hardly stay awake,” he said.
Michael Breus is a psychologist.Teens,he says,need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression(消沉) that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students?The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes.
Eric Peterson is the head of St.George’s School in the northeastern state of Rhode Island.He wanted to see if a thirty?minute delay(推遲)would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way.
小題1:What’s the best title for the passage?
A.Later classes,fewer sleepy teens

D.teenagers’ not studying seriously
小題3:Michael Breus thinks that________.
A.teens should get up early
B.teens need enough sleep to be lively
C.depression is common in teens
D.the first period class should be cut off
小題4:The last paragraph tells us________.
A.Eric Peterson visits the health center every day
B.it’s not easy for Eric Peterson to change start times
C.students in St.George’s School can get up later than before
D.students in St.George’s School aren’t late for school any more

She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday.
      When it comes to long life, Jeanne Calment is the world’s recordholder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span(壽命)? If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond?
      Researchers don’t entirely agree on the answers. “Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135, ”says Jerry Shay at the University of Texas.
      Steve Austad at the University of Texas agrees. “People can live much longer than we think, ”he says. “Experts used to say that humans couldn’t live past 110. When Calment blew past that age, they raised the number to 120. So why can’t we go higher? ”
      The trouble with guessing how old people can live to be is that it’s all just guessing. “Anyone can make up a number, ”says Rich Miller at the University of Michigan. “Usually the scientist who picks the highest number gets his name in Time magazine. ”
      Won’t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller, “adding another 50 percent would get you to 120. ”
      So what can we conclude from this little disagreement among the researchers? That life span is flexible(有彈性的), but there is a limit, says George Martin of the University of Washington. “We can get flies to live 50 percent longer, ”he says. “But a fly’s never going to live 150 years. ”O(jiān)f course, if you became a new species (物種), one that ages at a slower speed, that would be a different story, he adds.
      Does Martin really believe that humans could evolve (進化)their way to longer life? “It’s pretty cool to think about, ”he says with a smile.
小題1: What does the story of Jeanne Calment prove to us?
A.People can live to 122.
B.Old people are creative.
C.Women are sporty at 85.
D.Women live longer than men.
小題2: According to Steve Austad at the University of Texas, ______.
A.the average human life span could be 110
B.scientists cannot find ways to slow aging
C.few people can expect to live to over 150
D.researchers are not sure how long people can live
小題3: Who would agree that a scientist will become famous if he makes the wildest guess at longevity?
A.Jerry Shay. B.Steve Austad
C.Rich Miller D.George Martin
小題4: What can we infer from the last three paragraphs?
A.Most of us could be good at sports even at 120.
B.The average human life span cannot be doubled
C.Scientists believe mice are aging at a slower speed than before.
D.New techniques could be used to change flies into a new species

Eleven top universities are joining the Open University to launch free Internet courses. King’s College London, along with the Universities of Birmingham, Bristol, Cardiff, East Anglia, Exeter, Lancaster, Leeds, Southampton, St Andrews and Warwick, has partnered with FutureLearn, a company set up by the Open University that will offer free and non-credit bearing courses to Internet-users around the world.
The courses are modeled on the US phenomenon “Massive open online courses” ( Moocs ), which have attracted millions of users around the world and are especially popular in emerging economies.
FutureLearn will improve UK institutions for international students, said Prof Martin Bean, voice-chancellor of the Open University. “At the moment, foreign students’ perception of UK Universities is: wonderful history, great tradition, really good teaching, but a bit boring.”
Leeds University says the partnership will benefit students studying on campus. “Students will have access to a rich set of resources from both Leeds and our partners. They can also broaden their education beyond their main subject areas.”
The UK higher education industry stands among the top five export earners for Britain Moocs have grown rapidly in the US over the past year, with two providers leading the field. Coursera offers courses from 33 Universities, including Princeton, Brown, Columbia and Duke, and has reached more than 1.7 million users, EdX, a nonprofit start-up from Harvard and the Massachusetts Institute of Technology courses this autumn.
Simon Nelson, one of the key architects of BBC Online, will head FutureLearn as launch CEO. “It’s really meaningful for these universities to come together –we’ll punch much harder collectively than any other university will individually,” he said.
Partner Institutions will be responsible for their own content while the OU, which has been providing distance-learning courses since 1971, will assist with course delivery and infrastructure. Details of further universities will be revealed next year, as will the courses on offer.
小題1: What does the underlined word “perception” in paragrah3 mean?
A.expectationB.viewC.dreamD.proposal

The forces that make Japan one of the world's most earthquake-prone(有地震傾向的) countries could become part of its long-term energy solution.
Water from deep below the ground at Japan's tens of thousands of hot springs could be used to produce electricity.
Although Japanese high-tech companies are leaders in geothermal(地熱的) technology and export it, its use is limited in the nation.
"Japan should no doubt make use of its resources of geothermal energy," said Yoshiyasu Takefuji, a leading researcher of thermal-electric power production.
The disastrous earthquake and tsunami on March 11, 2011 caused a reaction against atomic power, which previously made up 30 percent of Japan's energy needs, and increased interest in alternative energies, which account for only 8 percent.
Artist Yoko Ono has called on Japan to explore its natural energy, following the example of Iceland which uses renewable energy for more than 80 percent of its needs.
For now, geothermal energy makes up less than 1 percent of the energy needs in Japan, which has for decades relied heavily on fossil fuels and atomic power.
The biggest problem to geothermal energy is the high initial cost of the exploration and constructing the factories.Another problem is that Japan's potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden.
"We can't even dig 10cm inside national parks." said Shigeto Yamada of Fuji Electric, adding that regulations protecting nature would need to be relaxed for geothermal energy to grow.
Researcher Hideaki Matsui said, "Producing electricity using hot springs is a decades-long project.We also have to think about what to do for now as energy supplies will decline in the short term."
The Earth Policy Institute in Washington, US, believed Japan could produce 80,000 megawatts(兆瓦)and meet more than half its electricity needs with geothermal technology.
Japanese giants such as Toshiba are already global leaders in geothermal technology, with a 70 percent market share.In 2010, Fuji Electric built the world's largest geothermal factory in New Zealand.
小題1:What would be the best title for the text?
A.Alternative energies in Japan
B.World's largest geothermal plant
C.Japan takes the lead in geothermal technology
D.Japan thinks of geothermal energy
小題2:What percentage of Japan's energy needs is geothermal energy?
A.About 8%.B.Below 1%.C.Around 30%.D.Over 80%.
小題3:According to Shigeto Yamada, the growth of geothermal power in Japan needs ____.
A.a(chǎn) change of rulesB.financial support
C.local people's helpD.high technology
小題4:Geothermal energy is considered as a long-term program by _____.
A.Yoshiyasu TakefujiB.Hideaki Matsui
C.Shigeto YamadaD.Yoko Ono
小題5:It can be learned from the last two paragraphs that _____.
A.the world's biggest geothermal plant was built by America
B.Japan will not export its geothermal technology
C.the potential of Japan's geothermal energy is great
D.it is hard to find geothermal energy in Japan
