8.No rows of desks in this classroom,and no teacher lecturing at the front.In fact,that's something Barrie teacher Liz Collett rarely does.Instead,she's on the move,talking to students about their work,from the small group sitting on the floor playing games to others nearby figuring out a math problem.
   The children in this class do not take a spelling test all year-in fact,the school avoids all pencil-and-paper tests-nor do they get assigned homework.Instead,their teacher gives them immediate feedback(反饋) on their work throughout the day.
   Welcome to the school of the 21st century,a place where teachers and students cooperate all the time.Such advanced classrooms are trying things,which some might consider as coddling kids-letting students give a voice-recorded essay instead of a written one or even allowing teens to design their own courses.
   Though some people blame schools for dumbing things down (降低教育標(biāo)準(zhǔn)),others will say such changes are actually based on the newest research on how to attract today's youth and increase not only their interests,but also their achievements.Many of today's school are not holding kid's interests.And if they're not interested,they're not learning-and isn't that the point?
"Students today say they want their education to be useful and valuable,and don't want it to be simply repeating the facts.That's the kind of learning that be happening for many kids,"says Penny Milton,a researcher."What we could argue is that to become good learners,they need to become thinkers."
   Jan Olson,anther researcher,says schools have been operating the same way since the Industrial Revolution.But the digital age is bringing an education revolution.While using technology is a part of it,what's important for students is being able to use information and understand it,not just remembering it.
   Today's learner needs fewer traditional tests and more"effective"feedback,ongoing discussion with a teacher,which studies have found is the number one factor in improving achievement.

27.Jan Olson thinks it important for students toC.
A.repeat the facts without really thinking

16.Many children first learn the value of money by receiving an allowance (pocket money).The purpose is to let children learn from experiences at an age when financial mistakes are not very costly.
The amount of money that parents give to their children to spend as they wish differs from family to family.Timing is another consideration.Some children get a weekly allowance.Others get a monthly allowance.
     In any case,parents should make clear what,if anything,the child is expected to pay for with the money.At first,young children may spend all of their allowance soon after they receive it.If they do this,they will learn the hard way that spending must be done within a budget (預(yù)算).Parents are usually advised not to offer more money until the next allowance.The object is to show young people that a budget demands a choice between spending and saving.Older children may be responsible enough to save money for larger costs,like clothing or electronics.
   Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home.These jobs are a normal part of family life.Paying children to do extra work around the house,however,can be useful.It can even provide an understanding of how a business works.
     Allowances give children a chance to experience the three things they can do with money.They can share it in the form of gifts or giving to a good cause.They can spend it by buying things they want.Or they can save it.
     Saving helps children understand that costly goals require sacrifice.You have to cut costs and plan for the future.Requiring children to save part of their allowances can also open the door to future saving and investing.Many banks offer services to help children and teenagers learn about personal finance.A saving account is an excellent way to learn about the power of compound interest.
     Compounding works by paying interest.So,for example,one dollar invested at two percent interest for two years will earn two cents in the first year.The second year,the money will earn two percent of one dollar and two cents,and so on.That may not seem like a lot,but over time it adds up.
32.Parents give their children allowances in order toC.
A.show off their wealth of family    
B.let them make more money
C.learn the value of money         
D.help children manage family finance
33.What is the second paragraph mainly about?D
A.The time to give allowances
B.The way to spend alloweances.
C.the amount of allowances given to children.
D.Considerations taken to give allowances.
34.Why are parents adivsed to offer yougn children allowances stricktly as planned?A
A.To help children learn to make a budget.
B.To have children save money for larger costs.
C.To let children make fewer mistakes.
D.To give them more allowances next time.
35.What does the author intend to tel lthe readers?C

13.Many adults enjoy a cup of coffee to have extra energy on a sleepy morning,and astronauts are  no exception.But having a drink in space isn't as easy as it is on the earth.You have to come up  with a whole new way to drink,and that's what scientists are trying to do.
"The coffee would be very hard to control in a normal cup,"said physics professor Mark Weislogel."You'd have to shake the cup toward your face and hope that some of the hot liquid floats toward your mouth.When it comes to guessing what liquids will do in new systems,we are often in the dark."
     Weislogel believes that creating a big zero-gravity cup would help improve the lives of  astronauts in space,so he and other researchers per formed a series of experiments with liquids on the International Space Station (ISS) to see how they move upwards on surfaces in zero gravity.
     In one of the tests,they placed two surfaces very close together to create a very narrow tunnel.They  wanted to see if liquid would easily flow up the tunnel.In another test,the researchers tried to figure out the best angle to place the narrow tunnel at so that the liquids would travel along the corners.
      The end result is a cup that doesn't look like a normal coffee cup at all.One side of the cup has a very sharp angle and,in zero gravity,the liquid naturally"flows"up that angled side of the cup,right up to the drinker's lips.
      The zero-gravity coffee cup is currently being tested on the ISS by astronaut Don Pettit,who worked with the researchers and helped them invent it."As you sip  (啜飲),more liquid keeps coming,and you can enjoy your coffee in a weightless environment-clear down to the last drop,"said Pettit,who thinks that future humans on Mars will be using this kind of cup to drink during celebrations!
61.We can learn from Paragraph l thatA.
A.a(chǎn)stronauts have difficulty drinking Coffee in space
B.coffee drinks in the morning can make astronauts sleepy
C.a(chǎn)stronauts drink coffee in the same way as on the earth
D.scientists have made coffee in zero gravity successfully
62.The underlined sentence in Para.2 may mean"C"
A.rooms in the Space Station lack light
B.scientists can't see anything in the dark
C.scientists know little about it
D.coffee can be drunk in the dark
63.What do we know about Weislogel's cup?D
A.It looks like a very narrow tunnel.
B.Each of its sides has a sharp angle.
C.It is the same as the normal cup we are using.
D.The liquid in it will flow to the drinkers itself.
64.According to Pettit,we can learn the coffee cup isA.
A.practical                              B.weightless
C.shapeless                              D.a(chǎn)wkward
65.What is the main idea of the passage?B
A.When humans will drink coffee on Mars.
B.How humans will drink coffee in zero gravity.
C.How experiments lead to unexpected patents.
D.When a normal cup can be used in space.

20.A patient on the brink of death has received the world's first self-contained artificial heart-a battery-powered device about the size of a softball that runs without the need for wires,tubes sticking out of the chest.It is powered by a small battery pack worn outside the body that transmits current through the skin.
Two surgeons from the University of Louisville implanted(植入)the titanium(鈦)and plastic pump during a seven-hour operation at Jewish Hospital Monday.The hospital said the patient was"awake and responsive''Tuesday and resting comfortably.It refused to eve personal details.
The patient had been expected to die within a month without the operation,and doctors said they expected the artificial heart to extend the person's life by only a month.But the device is considered a major step toward improving the patient's quality of life.
The new pump,called AbioCor,is also a technological leap from the mechanical hearts used in the l980s,which were attached by wires and tubes to large machinery outside the body.The most famous of those,the Jarvic-7,used air as a pumping device and was attached to an apparatus(器械)about the size of a washing machine.
"I think it's potentially a major step forward in the artificial heart development,''said Dr.David Faxon,president of the American heart Association.However,he said the dream of an implantable,permanent artificial heart is not yet a reality:"This is obviously an experimental device whose long-term success has to be demonstrated."Only about half of the 4,200Americans on a waiting list for donor hearts received  themlast year,and most of the rest died.
Some doctors,including Robert Higgins,chairman of cardiology(心臟病學(xué))at the Medical College of Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts."A donor heart in a good transplant can last l5to 30years.''he said."It's going be hard to replace that with a machine.''

56.The self-contained artificial heartC.
A.is made of titanium and pump
B.brought the patient to the brink of death
C.gets power from a battery pack without wires
D.was invented by two surgeons from University of Louisville
57.From the text we can knowB.
A.the patient recovered completely
B.the patient got better after the operation
C.the patient refused to obtain a donor heart
D.the patient died a month later after the heart implantation
58.What can we learn about the Jarvic-7?B
A.It is a technological leap today.
B.It could be used most widely in the l980s.
C.It is as advanced as AbioCor.
D.It must be attached to a washing machine.
59.Dr.David Faxon thinks the self-contained heartD.
A.has achieved a long-term success
B.will replace donor hearts
C.is an implantable and permanent artificial heart
D.is still in the experimental stage
60.What does the underlined word"them''in Paragraph 5refer to?A
A.donor hearts           B.a(chǎn)rtificial hearts
C.experimental devices   D.heart operations.

17.People are being lured (引誘) onto Facebook with the promise of a fun,free service without realizing they're paying for it by giving up large amounts of personal information.Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don't realize this is happening.Even if they know what the company is up to,they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.
The biggest problem,however,is that the company keeps changing the rules.Early on,you keep everything private.That was the great thing about facebook-you could create your own little private network.Last year,the company changed its privacy rules so that many things-your city,your photo,your friends'names-were set,by default (默認(rèn)) to be shared with everyone on the Internet.
According to Facebook's vice-president Elliot Schrage,the company is simply making changes to improve its service,and if people don't share information,they have a"less satisfying experience".
Some critics think this is more about Facebook looking to make more money.Its original business model,which involved selling ads and putting them at the side of the page,totally failed.Who wants to look at ads when they're online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington.In April,Senator Charles Schumer called on Facebook to change its privacy policy.He also urged the Federal Trade Commission to set guidelines for social-networking sites."I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,"Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy is only the beginning,which is why I'm considering deactivating(撤銷) my account.Facebook is a handy site,but I'm upset by the idea that my information is in the hands of people I don't know.That's too high a price to pay.

31.What do we learn about Facebook from the first paragraph?C
A.It is a website that sends messages to targeted users.
B.It makes money by putting on advertisements.
C.It profits by selling its users'personal data.
D.It provides loads of information to its users.
32.What does the author say about most Facebook users?B
A.They are reluctant to give up their personal information.
B.They don't know their personal data enriches Facebook.
C.They don't identify themselves when using the website.
D.They care very little about their personal information.
33.Why does Facebook make changes to its rules according to Elliot Schrage?A
A.To provide better service to its users.
B.To follow the Federal guidelines.
C.To improve its users'connectivity.
D.To expand its scope of business.
34.What does Senator Charles Schumer advocate?C
A.Setting guidelines for advertising on websites.
B.Banning the sharing of users'personal information.
C.Formulating regulations for social-networking sites.
D.Removing ads from all social-networking sites.
35.Why does the author plan to cancel his Facebook account?C
A.He is dissatisfied with its current service.
B.He finds many of its users untrustworthy.
C.He doesn't want his personal data abused.
D.He is upset by its frequent rule changes.
