2.But University of Pittsburgh graduate Micah Toll,23,and a few friends recently launched an invention that they hope will, increase the city's pedal power:An electric bike called a Pulse PEVO.AM super-strong battery powers the bicycle.Able to hit nearly 20 miles per hour without pedaling,it zips up the city' s most daunting(令人却步的)hills.Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.
3.If it sounds like Toll has a knack(窍门)for fixing problems,that's because he does.In high school,he designed a new type of construction beam.It weighs no more than a feather pillow but can be used to build sturdy(坚固的)homes for refugees fleeing war or natural disaster.For his work , Toll was invited to attend the Intel International Science and Engineering Fair(ISEF)-twice,in 2006 and 2007.The annual competition for young researchers is a program of Society for Science&the Public(that's the parent organization of Science News for Kids).Toll says that when it comes to science,he keeps it simple:"You see a problem and say,‘How could I solve that?’",
4.He's not the only one to take that approach.Many young researchers get their start by trying to solve a problem or fulfill a need in their own communities.When students dedicate themselves to finding a solution that may benefit their community , " a passion is ignited,(点燃),"says Wendy Hawkins , executive director of the Intel Foundation,which sponsors Intel ISEF."Finding that passion and fostering it can be the key to many students'future success."she says.

    1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.
    Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep .Most crashes result from human and not mechanical faults.
    Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.
    And improvements to seat belts , pedal(脚踏)controls and tyres are making driving smoot- her and safer. The colour of a car has been found to be linked with safety,as have,less surpris- ingly,size and shape.
    But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations(创新).Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.
    Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.
    Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone's personal chauffeur(司机),but their latest efforts suggest that won't be soon.

    Satellite tracking and remote communication systems can be used to______.
    A: reduce oil consumption
    B: remove the obstacles on the road
    C: call for help when one's car crashes
    D: help drivers get out of a traffic jam

    答案:C
    解析:
    本题的答案在第一段第二句话“much research now is focused on safety and new fu-els",所以正确答案是D,改善汽车的安全和发展新型燃料。


    第二段最后一句话明确指出“most crashes result from human and not mechanical faults",选项B中human mistakes即human faults.


    选项B和C的内容在文中第三段提到“Radar can spot obstacles in fog , while other technology ‘ sees through ’ big vehicles blocking your view”,选项D在第四段中第一句话 提到“...improvements to seat belts,pedal controls and tyres are making driving smoother and safer.”只有选项A未被提及。


    本题的答案可以直接从第五段倒数第一句话中找到“Satellite tracking and remote communications can also came into play if you crash , automatically calling for help.”这里 come into play是开始起作用的意思。


    文章最后一句话指出机器人司机可以使交通运行更通畅,也许有一天机器人会成为每个人的私人司机,但是最近的研究表明这个愿望不会很快实现,这正是选项A所 表达的意思“It will take some time before robotic drivers are available.”其他三个选项的内容文章根本就没有提及。

    Passage Three
    Americans are well known for the strange diets they always seem to be following.It seems that Americans like to diet almost as much as they like to eat.New types of diet plans are always coming out.Usually,though,they don't stay popular for long.
    There are many diets on the market.It is often difficult to know which ones really work.It's also hard to believe how fast a dieter is supposed to shed pounds.A lot has been written about dieting.And some interesting facts about diets and foods have been discovered.
    For example,did you know that the more celery you eat,the more weight you will lose?Celery has“negative”calories.The body burns up more calories digesting a piece of celery than there are in the celery stick itself.
    Dieters?shun?potatoes because they think they are fattening.But they aren't.A potato has about the same number of calories as an apple.To gain a single pound,you would have to eat eleven pounds of potatoes!
    Some dieters even worry about getting fat from licking postage stamps.But they have nothing to worry about.The glue on an average stamp has only about one-tenth of a calorie.Maybe a diet of post-age stamps would be popular?

    This passage is all about______

    A.vegetables
    B.fads
    C.Americans
    D.dieting

    The Industrial Age and Employment

    The industrial age has been the only period of human history in which most people's
    work has taken the form of jobs.The industrial age may now be coming to an end,and
    some of the changes in work patterns which it brought about may have to be reversed.This
    seems a daunting(大胆的)thought. But, in fact, it could offer the prospect of a better
    future for work.Universal employment,as its history shows,has not meant economic freedom.
    Employment became widespread when the enclosures of the 17th and 18th centuries
    made many people dependent on paid work by depriving(剥夺)them of the use of the
    land,and thus of the means to provide a living for themselves.Then the factory system
    destroyed the cottage industries and removed work from people's homes.Later,as
    transport improved, first by rail and then by road, people commuted(乘车往返)longer
    distances to their places of employment until,eventually,many people's work lost all
    connection with their home lives and the places in which they lived.
    Meanwhile,employment put women at a disadvantage.In pre-industrial times,men
    and women had shared the productive work of the household and village community.Now it
    became customary(惯例的)for the husband to go out to paid employment, leaving the
    unpaid work of the home and family to his wife.Tax and benefit regulations still assume this
    norm today,and restrict more flexible sharing of work roles between the sexes.
    It was not only women whose work status suffered.As employment became the

    Motoring Technology
    1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.
    Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don't miss important road signs or fall asleep .Most crashes result from human and not mechanical faults.
    Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology"sees through"big vehicles blocking your view.
    And improvements to seat belts , pedal(脚踏)controls and tyres are making driving smoot- her and safer. The colour of a car has been found to be linked with safety,as have,less surpris- ingly,size and shape.
    But whatever is in the fuel tank,you don't want a thief in the driving seat and there have been many innovations(创新).Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.
    Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.
    Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone's personal chauffeur(司机),but their latest efforts suggest that won't be soon.

    According to the second paragraph,most road accidents happen due to______.
    A:.heavy traffic
    B: human mistakes
    C: engine failure
    D: bad weather

    答案:B
    解析:
    本题的答案在第一段第二句话“much research now is focused on safety and new fu-els",所以正确答案是D,改善汽车的安全和发展新型燃料。


    第二段最后一句话明确指出“most crashes result from human and not mechanical faults",选项B中human mistakes即human faults.


    选项B和C的内容在文中第三段提到“Radar can spot obstacles in fog , while other technology ‘ sees through ’ big vehicles blocking your view”,选项D在第四段中第一句话 提到“...improvements to seat belts,pedal controls and tyres are making driving smoother and safer.”只有选项A未被提及。


    本题的答案可以直接从第五段倒数第一句话中找到“Satellite tracking and remote communications can also came into play if you crash , automatically calling for help.”这里 come into play是开始起作用的意思。


    文章最后一句话指出机器人司机可以使交通运行更通畅,也许有一天机器人会成为每个人的私人司机,但是最近的研究表明这个愿望不会很快实现,这正是选项A所 表达的意思“It will take some time before robotic drivers are available.”其他三个选项的内容文章根本就没有提及。

    A Pulse PEVO is powered with______.
    A:a nearly 40-degree angle
    B:get on bikes

    答案:E
    解析:
    第一段表明,匹兹堡多山,而且街道的坡度很陡,因此许多人不骑自行车出行。由此可知,第一段主要讲的是人们在匹兹堡不骑自行车的原因。
    第二段主要表明,Toll发明的超能电池能够为自行车提供更强的动力,可鼓励匹兹堡的人骑自行车出行。由此可知,本段主要讲的是一项能够增强自行车动力的发明。
    第三段的主题句是第一句,紧接着列举Toll在高中设计新型建筑横梁的例子,主要表明 Toll有解决问题的窍门和热情。
    第四段表明,只要能使他们的集体受益,年轻的研究者们对解决问题非常有激情。由第三句中的passion一词也可知C项正确。
    根据第二段第二句可知,为Pulse PEVO提供动力的是一种超强电池。
    由第二段最后一句可知,Toll希望Pulse PEVO能鼓励匹兹堡和其他地方的人骑自行车。encourage是persuade的同义转换。
    由第三段第二、三句可知,Toll设计的建筑横梁与羽毛枕头差不多重。
    由第四段第三句“…that may benefit their community…”可知,本题应该选择F项。

    The Industrial Age and Employment

    The industrial age has been the only period of human history in which most people's
    work has taken the form of jobs.The industrial age may now be coming to an end,and
    some of the changes in work patterns which it brought about may have to be reversed.This
    seems a daunting(大胆的)thought. But, in fact, it could offer the prospect of a better
    future for work.Universal employment,as its history shows,has not meant economic freedom.
    Employment became widespread when the enclosures of the 17th and 18th centuries
    made many people dependent on paid work by depriving(剥夺)them of the use of the
    land,and thus of the means to provide a living for themselves.Then the factory system
    destroyed the cottage industries and removed work from people's homes.Later,as
    transport improved, first by rail and then by road, people commuted(乘车往返)longer
    distances to their places of employment until,eventually,many people's work lost all
    connection with their home lives and the places in which they lived.
    Meanwhile,employment put women at a disadvantage.In pre-industrial times,men
    and women had shared the productive work of the household and village community.Now it
    became customary(惯例的)for the husband to go out to paid employment, leaving the
    unpaid work of the home and family to his wife.Tax and benefit regulations still assume this
    norm today,and restrict more flexible sharing of work roles between the sexes.
    It was not only women whose work status suffered.As employment became the
    dominant form of work,young people and old people were excluded-a problem now,as
    more teenagers become frustrated at school and more retired people want to live active lives.
    All this may now have to change.The time has certainly come to switch some efforts
    and resources away from the utopian(乌托邦的)goal of creating jobs for all, to the urgent
    practical task of helping many people to manage without full-time jobs.
