4.There are so many different plastic cards that adults have to carry around-library cards,savings cards for different banks,credit cards,just to name a few…So why not have one to replace them all?
Scott Barnhill,an 1l-year-old fifth-grade student in the US,has come up with an idea for a"Security One Card".
Sound smart?The US Patent(專利) Office thought so,and it approved a patent for his idea in April.
Here's an example of how Barnhill's idea would work.
Let's say you have the three cards mentioned above.Instead of carrying them all,you could have just one by having additional magnetic strips(磁條) added to it.
The magnetic strips can be added to any plastic card,even a blank one.
Companies could add their information to one of the strips.For example,you could ask a library to add a strip to your bankcard.
Barnhill has a lot of hobbies,including designing websites.He got the idea at the age of 9when he saw his father using a keycard to enter their hotel room.He thought,"The hotels are wasting money with the key cards."So,instead of using a hotel-issued key card,guests could use their credit cards--if the hotel added a special magnetic strip.At check-out,the strip would simply be removed.
Now that he has his patent,his next step is a letter-writing campaign to get support from major credit card companies.
"I'm going to be writing letters to credit card companies to ask if they can co-operate.I hope they'll give me money every time someone puts a strip on the back of another card,or every time the idea is used,"Barnhill said."I'll write the letters and see what they say.If they say no,I'll ask someone else,another credit card company."
He is hoping to make money from his patent and has decided it would be better to collect royalties(專利使用費)rather than sell his patent if the idea   take off.
"The ATM person who invented that sold it totally,and if he'd chosen royalties he'd get like 2cents for every transaction (交易) and he'd be a billionaire now,"Scott said.

68.The immediate cause of Scott's invention was thatC.
A.he found that adults have to carry around so many plastic cards
B.he realized it's big waste to make so many plastic cards instead of only one
C.he found even a hotel issued its own cards--keycards
D.he realized it would be a good chance to make big money
69.The advantage of"Security One Card"is that itC.
A.could remove the burden of taking all kinds of plastics cards
B.would he very safe
C.could save your money
D.could have a lot of magnetic strips on it
70.The underlined phrase"takes off"in the last but one paragraph probably meansB.
A.makes money         B.wins a lot of support
C.is worth a lot      D.is practical
71.From the story,we can see Scott isC.
A.more magic than smart             B.clever but lazy
C.creative,determined and wise     D.far-sighted.

19.Welcome to the world of multitasking-a place where the measure of a person is how many jobs they can perform at the same time.In fact,if experts are to be believed,multitasking is a disastrous idea.
One of the opponents of multitasking is Dr.Clifford Nass,a professor at Stanford University."People who multitask frequently are less able to pay attention; they're worse at managing their memory."he said.In his opinion,the loss that we get with multitasking is harmless in some situations,for example,part of doing business in the digital world:but you can't do serious work like writing,thinking or solving an important problem this way.You do worse even as you think you're doing better.All the time the research points to a simple fact:the brain cannot cope.When you stop midway through composing a report to check an email,you force your brain to stop and regroup.It is like pressing the pause button during a movie,meaning the film takes longer to watch.
And as for Dr.Nass,the problems extend beyond the brain.Young people who frequently multitask are not as socially and emotionally healthy as those who don't.They just feel more emotionally satisfied and the feeling is so good and they are bound to desire it again.Todd Oppenheimer,a writer said"We've become a very short-term society and don't reward people for taking a lot of time on something."He fears we may end up losing the next generation of great thinkers."It's really unfortunate because the long-term challenges of our world-environmental issues,financial issues-require people to think wisely about the long-term consequences of what they do.And it's no coincidence that the kind of people who do think long-term don't multitask."

29.According to Dr.Nass,multitaskingD.
A.makes the performance emotionally affected only
B.contributes to memorizing various things
C.may result in losing the next generation of great thinkers
D.can be performed using digital tools
30.From the passage,we can tellB.
A.the loss that we get with multitasking is harmless
B.we mistakenly believe that we're doing better by switching between tasks
C.doing multitasking does harm to us in every area
D.for every task you add to your multitasking,you can finish your goal quicker
31.Which of the following is a multitasking addict?C
A.You turn your cellphone to silence when you're out to dine with friends.
B.You watch from start to finish without distraction when playing a DVD.
C.You have your office desk covered with paperwork from various unfinished projects.
D.You feel that when you try to do too much at once,the result always suffers.
32.The author mainly wants to tell usA.
A.the less you switch,the better you do
B.it is more efficient to do things all in a mixed way
C.it takes longer for us to become a great thinker
D.we shouldn't be lazy if we want to accomplish many tasks.

9.For centuries,the body's blood has been linked closely with the emotions.People who show no human emotions or feelings,are said to be cold-blooded killer.For example,the police are searching for a cold-blooded killer.He seems to kill for no reason,and no emotion,as if taking someone's life as nothing.
Cold can affect other parts of the body.The expression"get cold feet"has nothing to do with cold or your feet.The expression means being afraid to do something you have decided to do.For example,you agree to be president of an organization.But then you learn that all the other officers have resigned (辭職),and all the work of the organization will be your responsibility.You are likely to get cold feet about being president when you understand the situation.
The expression"give someone the cold shoulder"probably comes from the physical act of turning your back toward someone,instead of speaking to him face to face.You may give a cold shoulder to a friend who has not kept a promise he made to you.Or,to someone who has lied about you to others.
A cold fish is not a fish.It is a person.But it is a person who is unfriendly,unemotional and shows no love or warmth.A cold fish does not offer much of himself to anyone.Someone who is a cold fish could be cold-hearted.Now a cold-hearted person is someone who has no sympathy(同情).Several popular songs in recent years were about cold-hearted men or cold-hearted women who,without feelings,broke the hearts of their lovers.
Out in the cold means not getting something that everybody else got.A person might say that everybody but him got a pay raise---he was left out in the cold.And it is not a pleasant place to be.

67.There areA expressions related to cold that are mentioned in the passage.
A.6   B.4    C.3     D.7
68.When you refuse to speak to a man and treat him in a distant way,you may express by"C".
A.I think he is a cold fish
B.I think he is a cold-blooded man
C.I give him the cold shoulder
D.I'm likely to get cold feet
69.We can use the expression"C"to describe a man who hurts his lover without mercy.
A.cold-blooded    B.cold shoulder   C.cold-hearted    D.cold feet
70.The topic of this passage is aboutB.
A.the relationship between cold and our body
B.some expressions connected with cold
C.some expressions about friendship
D.how cold weather comes into being.

16.As any homemaker who has tried to keep order at the dinner table knows,there is far more to a family meal than food.Sociologist Michael Lewis has been studying 50families to find out just how much more.
Lewis and his co-workers carried out their study by videotaping (錄像) the families while they ate ordinary meals in their own homes.They found that parents with small families talk actively with each other and their children.But as the number of children gets larger,conversation gives way to the parents'efforts to control the loud noise they make.That can have an important effect on the children."In general the more question-asking the parents do,the higher the children's IQ scores,"Lewis says."And the more children there are,the less question-asking there is."
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings (兄弟姐妹).Lewis found that in families with three or four children,dinner conversation is likely to center on the oldest child,who has the most to talk about,and the youngest,who needs the most attention."Middle children are invisible,"says Lewis."When you see someone get up from the table and walk around during dinner,chances are it's the middle child."There is,however,one thing that stops all conversation and prevents anyone from having attention:"When the TV is on,"Lewis says,"dinner is a non-event."
67.The writer's purpose in writing the text is toA.
A.report on the findings of a study
B.give information about family problems
C.teach parents ways to keep order at the dinner table
D.show the relationship between parents and children
68.Parents with large families ask fewer questions at dinner becauseB.
A.they are busy serving food to their children
B.they are busy keeping order at the dinner table
C.they have to pay more attention to younger children
D.they are tired out having prepared food for the whole family
69.By saying"Middle children are invisible"in paragraph 3,Lewis means that middle childrenA.
A.get the least attention from the family
B.have to help their parents to serve dinner
C.a(chǎn)re often kept away from the dinner table
D.find it hard to keep up with other children
70.Which of the following statements would the writer agree to?D
A.It is important to have the right food for children.
B.It is a good idea to have the TV on during dinner.
C.Elder children should help the younger ones at dinner.
D.Parents should talk to each of their children frequently.

13.You have two eyes and they are set close together on the front of your face.Have you wondered why?The reasons are simple and important to the way you see the rest of your world.
 Your eyes are like two small cameras.A camera catches an image of an object and records it on film.Similarly,when you look at something,each eye takes in what it sees and sends this image to the back of the eyeball.Because your eyes are set close together,they view the world from about the same height but from slightly different angles.Working as a team,the eyes send the images to your brain,which puts them together into a single,centered image.
 Seeing in stereo means seeing with two eyes working together,which is called stereoscopic sight.This allows you to view the world in three dimensions,or 3-D.Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it.If images are coming from only one eye,however,only two of these dimensions----height and width----can be perceived.A world seen with one eye is thus two-dimensional,as in a photograph.
Now consider why your two eyes are on the front of your face.Think of other animals with the same arrangement.They are all animals that hunt,like lions and wolves.Their eyes face directly in front of them.This provides a field of sight about 180 degrees wide,which is called binocular(雙眼的) sight.On the other hand,animals that are hunted have eyes on the sides of the head,which provides nearly360-degree field of sight.In order to stay alive,they need to see things coming from the sides and from behind.However,without stereoscopic sight,they have difficulty determining how far a danger is.
 With sight both stereoscopic and binocular,humans share with animal hunters the ability to see from side to side and to accurately determine the distance.If you think it would be great to have another type of sight,perhaps with hundreds of tiny eyes like many insects do,think again!Each tiny insect eye sees only a tiny part.Besides,what if you needed glasses?Be glad for the eyesight that you have.
67.According to the passage,the similarity of an eye and a camera is that they bothB.
A.can imagine objects              
B.can record images
C.provide centered images          
D.work at the same height
68.Stereoscopic sight is a result of havingA.
A.two eyes close to each other that work together
B.hundreds of eyes,all seeing tiny parts of an image
C.a(chǎn) three-hundred-sixty-degree field of sight
D.one eye on either side of the head,each seeing a different image
69.What is the meaning of the underlined word"perceived"in Para3 most similar to?B
A.known         B.seen         C.taken            D.understood
70.We can infer from the last paragraph thatD.
A.our eyes work like cameras
B.a(chǎn)nimal hunters are glad for the sight they have
C.the three dimensions are depth,height and width
D.human beings are fortunate to have such eyesight.

14.Every electronic gadget (小玩意) needs good memory.A music player stores songs,albums and playlists.A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game.Mobile phones store names,numbers and hundreds of texts.
Now,scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information,but it's a start.In the future,a cell-based gadget might travel through the body and record measurements.The benefit to human health could be big:the right tool,for example,might record the earliest signs of disease.
Doctors,scientists and other curious people want to know what is happening inside the body,even at levels that can't be seen by the naked eye.So far,there is no device small enough to travel through the bloodstream.
If normal machines won't do the trick,perhaps biology will.Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools.In the case of the new memory device,bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA.Found in nearly every cell,DNA carries all of the information that keeps a living thing alive.
In the new experiment,the researchers turned DNA from bacteria(細菌) into a switch.They"flip (翻轉(zhuǎn))"a small section of DNA.Then,using the same procedure (過程),the scientists flip the section again-returning it into its normal structure.
Using these DNA switches,"We can write and erase DNA in a living cell,"bioengineer,Jerome Bonnet,explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical.Right now,it takes one hour to complete a flip.That is far too long to be useful.Plus,a flipped section has a very small little memory-less than what a computer uses to remember a single letter.
"This was an important proof that it was doable,"Bonnet told Science News."Now we want to build a more complex system,something that other people can use."
67.What is the aim of listing the electronic things in the first paragraph?D
A.To make the passage more fashionable.
B.To show how electronic things have memory.
C.To discuss things in detail.
D.To make the subject of the text more understandable.
68.What is possible future benefit of the cell-based gadget for people?A   A.To detect disease at the earliest point.
B.To help improve the memory.
C.To help people build a body.
D.To replace many electronic gadgets.
69.What is the object being researched?B
A.The cells of bacteria.
B.The DNA of bacteria.
C.A section of bacteria.
D.The nucleus of bacteria.
70.What do we know about a flipped section of DNA?A
A.It has a very small memory.
B.It can function as a computer.
C.It has one letter in it.
D.It takes a day to complete it.
