20.Imagine you're at a party full of strangers.You're nervous.Who are these people?How do you start a conversation?Fortunately,you've got a thing that sends out energy at tiny chips in everyone's name tag.The chips send back names,jobs,hobbies,and the time available for meeting-whatever.Making new friends becomes simple.
This hasn't quite happened in real life.But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product,under your pet's skin,even under your own skin.Passive RFID tags have no energy source-batteries because they do not need it.The energy comes from the reader,a scanning device,that sends out energy (for example,radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object,and the data can be updated.Already,RFID technology is used for recognizing each car or truck on the road and it might appear in your passport.Doctors can put a tiny chip under the skin that will help locate and obtain a patient's medical records.At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10or 12years ago,you would have heard about the coming age of computing.One example always seemed to surface:Your refrigerator would know when you needed to buy more milk.The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.
RFID tags are a small part of this phenomenon."The world is going to be a loosely coupled set of individual small devices,connected wirelessly,"predicts Dr.J.Reich.Human right supporters are nervous about the possibilities of such technology.It goes too far tracking school kids through RFID tags,they say.We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it.And how many beers.Accompanied by how many biscuits.
When Marconi invented radio,he thought it would be used for ship-to-shore communication,not for pop music.Who knows how RFID and related technologies will be used in the future.Here's a wild guess:Not for buying milk.

74.The article is intended toD.
A.warn people of the possible risks in adopting RFID technology
B.explain the benefits brought about by RFID technology
C.convince people of the uses of RFID technology
D.predict the applications of RFID technology
75.We know from the passage that with the help of RFID tags,peopleA.
A.will have no trouble getting data about others
B.will have more energy for conversation
C.will have more time to make friends
D.won't feel shy at parties any longer
76.Why are some people worried about RFID technology?C.
A.Because children will be tracked by strangers.
B.Because market competition will become more fierce.
C.Because their private lives will be greatly affected.
D.Because customers will be forced to buy more products.
77.The last paragraph implies that RFID technologyB.
A.will not be used for such matters as buying milk
B.will be widely used,including for buying milk
C.will be limited to communication uses
D.will probably be used for pop music.

分析 本文主要講述的是一項(xiàng)新技術(shù)RFID的應(yīng)用及它的前景,不僅可以交友還可以付賬.不過隨之也會產(chǎn)生安全的問題.

解答 74.D 主旨大意題.通讀全文得知,本文主要講述的是一項(xiàng)新技術(shù)RFID的應(yīng)用及預(yù)測它的前景應(yīng)用.故選D.
75.A 細(xì)節(jié)理解題.根據(jù)第一段"Fortunately,you've got a thing that sends out…and the time available formeeting-whatever",人們第一次見面便可以從芯片上獲取對方的基本信息.可推知選A.
76.C 細(xì)節(jié)理解題.根據(jù)第六段"Human right supporters are nervous…It goes too far tracking…Accompanied by how many biscuits"這種技術(shù)也會使人們隱私泄露,甚至有的公司知道人們的飲食情況,可知選C.
77.B 推理推斷題.根據(jù)最后一段提到的Marconi在發(fā)明收音機(jī)時只想應(yīng)用在輪船與陸地沿岸的交流溝通,沒想到應(yīng)用在流行音樂上,因而誰知道RFID及相關(guān)技術(shù)在未來將怎樣使用,可能會用在買牛奶的問題上.故選B.

點(diǎn)評 在對科技說明文進(jìn)行閱讀理解是,考生可以尤其注意中心句,中心段(首尾)、轉(zhuǎn)折句和問題中出現(xiàn)的詞,尤其是一些很有特點(diǎn)的詞如專有名詞.在文段中快速找到相應(yīng)詞語所在位置,問題的答案往往就在附近.

11.Defenders of the French language are angered by plans to introduce courses taught in English at public universities,arguing that France must protect itself against the risk of losing its culture identity.
The French Parliament recently started to debate the issue as part of a bill on a broader reform of higher education,but all attention has focused on an article that would lift a 19-year ban on English as a teaching language at public universities.
The French government backs the change,which it says would help French graduates compete in a global economy as the country struggles to regain competitiveness.More French students fearing poor job prospects at home,where youth unemployment is nearly 25percent,are studying and working abroad.One of their main destinations is London,which now has the sixth largest French population in the world.
However,opponents of the bill,including professors,lawmakers and the French language supervision body Academic France,say the global community of French-speaking peoples must be defended and that the change would be a betrayal(背叛) of other French-speaking nations."If France gives other French-speaking countries the wrong signal by leading an attack against the language,that would be a very,very regrettable thing indeed,"said Claude Hagege,a language scientist.
France has long defended its culture at home and abroad.In 1994,the so-called"Toubon Law"made the use of French compulsory in all TV broadcasts,meaning all foreign-language programs are dubbed(配音),while radio stations must play at least 40percent of French music for most of the day.
Business leaders criticize France's low ranking for English proficiency(熟練度)-it placed 23rd in a 2012global ranking published by education company Education First-even though the use of English has grown notably in academic circles.
Higher Education Minister Genevieve Fioraso said offering English would increase the appeal of French universities at a time when they are falling further behind in international rankings.In a 2011-2012survey by Britain's Times newspaper,the highest-ranked French university is in the 59th position.Private business schools where English is taught rank higher.
(Note:Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

78.What does"the change"in Paragraph 3refer to?Allowing using English as a teaching language at public universities.
79.Some people are against the change because they think it wouldbe a betrayal of other French-speaking nations/make France lose its cultural identity.
80.According to"Toubon Law",what is a must for TV stations in France?Using French in all TV broadcasts/The use of French in all TV broadcasts.
81.Genevieve Fioraso thinks the release of the bill may help French universitiesattract more students/be more appealing/rank higher in international rankings.

8.Common phrases like"no pains,no gains"give the impression that we ought to be suffering while we study.It's almost as though the only way to know if we're putting in enough work is the sense of hardship we bear.
When we haven't taken the time to come up with another idea,all we know how to do is shut ourselves in a room with a book.It's no surprise that we find revision boring and difficult.Just as children learn from playing,we can learn from doing,or at least from study techniques that interest us,rather than make us switch off.
Shutting yourself away can make you learn to hate studying.This leads to a situation where instead of being able to concentrate on your work,you are troubled by how unfair it is that you must study.
When you hate your work it's very difficult to make yourself star,or approach it with any kind of structure or enthusiasm.This can be part of a vicious cycle(惡性循環(huán)) that traps you into ineffective revision,your poor progress fuelling further annoyance.
Just being around other people really helps fight against feelings of loneliness and,thankfully,it's perfectly possible to work in the company of other people.We just need to learn how to deal with distractions(使人分心的事物).
It's not necessary to avoid all company,just idle(懶散的) company.Studying in the same room as someone who is ironing or working out is perfectly possible.People who are bored and looking to be distracted,however,are terrible to work around.They constantly try to keep others in conversation.
It's also a good idea to avoid the company of people involved in activities that you would rather be doing than studying.Working while sitting next to someone playing video games is much more likely to end with a new high score than a productive few hours of revision.
If being around others means working in a noisy environment,a pair of headphones and some background music can block out even noisy children.They also act as a psychological barrier,so that people think twice before interrupting you.
When you're studying for a big exam,it seems like your whole life is taken up with study.Friends and family can lessen feelings of isolation(孤立).And connecting with other people makes us happy,so it's important not to give that up and to make sure that we take the time to socialize.
51.The author might believe that the phrase"no pains,no gains"D.
A.best describes how to study well        
B.makes people treat study as a habit
C.encourages people to learn step by step     
D.is not a good inspirational phrase for study
52.Which saying about study might the author prefer?C
A.There is no royal road to learning.
B.It's better to work behind closed door.
C.A positive motivation leads to good study results.
D.He who is ashamed of asking is ashamed of learning.
53.Which might lead to an effective study based on this text?C
A.A correct goal.B.A good teacher.
C.A favorable interest.D.A hard task.
54.The underlined sentence in Paragraph 7 implies thatB.
A.playing video games is helpful for an effective study
B.one shouldn't let a video player to be his/her company
C.one should study from certain activities that he/she is interested in
D.the more time one spends in playing games,the higher marks he/she will get
55.If you are studying in a noisy environment,you'd betterA.
A.give indication of not wanting to be interrupted
B.give up others'company at one
C.think twice before taking any action

15.On the high-speed train Avignon to Paris,my husband and I landed in the only remaining seats on the train in the middle of a car,directly opposite a Frenchwoman of middle years.It was an extremely uncomfortable arrangement to be looking straight into the eyes of a stranger.My husband and I pulled out books.The woman produced a large makeup case and made up her face.Except for a lunch break,she continued this activity for the entire three-hour trip.Every once in a while she surveyed the car with a bright-eyed glance,but never once did she catch my eye.My husband and I could have been a blanket wall.
     I was amused,but some people would have felt uncomfortable,even repulsed(厭惡的).there is something about making up in public that calls up strong emotional reactions.Partly it's a question of hygiene.And it's a matter of degree.Making up----a private act----has a way of neglecting the presence of others.I was once seated at a party with a model-actress who immediately waved a silly brush and began dusting her face at the table,demonstrating that while she was next to me,she was not with me.
     In fact,I am generally prohibited from making up in public,except when I am in the company of cosmetics moment.In a gathering more professional than social,I would do so.
     Kathy Peiss,a history professor at the University of Massachusetts in Amherst says that nose-powdering in the office was an occasion for outrage in 1920's and 30's.Deploring(強(qiáng)烈反對) the practice as a waste of company time,trade journals advises managers to discourage it among workers.Peiss theorizes that it was female's making up in what has been an all-male field that disturb some gentlemen.
      Peiss tells me that after the 30's,pulling out a make-up case was no longer an issue.It became an accepted practice.I asked if she feels free to apply lipstick at a professional lunch herself.Sounding mildly shocked,she says she would save that for the privacy of her car afterward.Why?Because it would be"a gesture of inappropriate feminity(女性化)."One guess is that most professional women feel this way.There is evidence of the popularity of the new lipsticks that remain in place all day without retouching.

61.According to the author,"My husband and I could have been a blanket wall."(Line 6,Para.1)most probably means"A".
A.We were of no existence in the French woman's eyes.
B.We looked at the French woman expressionlessly.
C.We were treated with an expressionless face.
D.We used books as a wall to avoid the woman's eyes.
62.In the author's opinion,sheD.
A.feels comfortable when making up in public.
B.makes up before any professional gatherings.
C.only makes up on social occasions.
D.a(chǎn)llows public making up on certain occasions.
63.According to Peiss,nose powdering in an office was criticized mainly for the reason thatB.
A.normal office work was disturbed.
B.make dominance was emphasized there.
C.it discouraged women's interest in career.
D.it distracted make workers'focus on work.
64.Why do most professional women give up using lipsticks in public?D
A.Because they are worried about being looked down upon.
B.Because it implies women's disadvantages in academic fields.
C.Because they are ashamed to be seen making up in front of males.
D.Because it emphasizes their female features in wrong situations.
65.It can be inferred that in a highly open society,the differences between men and womenC.
A.have attracted little attention.
B.hinder the social development.
C.still call for great concern.
D.a(chǎn)re attractive topics in talk shows.

9.No one knows why people dream,but some dreams might be connected to the mental processes that help us learn.In a recent study,scientists found a connection between nap-time (午睡時間) dreams and better memory in people who were learning a new skill.
So perhaps one way to learn something new is to practice,practise,practise---and then sleep on it.
"I was surprised by this finding,"Robert Stickgold,a Harvard University scientist who led the study.
In the study,100 college students each spent an hour on a computer,trying to get through a virtual maze (虛擬迷宮).The maze was difficult,and the study participants had to start in a different place each time they tried---making it even more difficult.
Then,for the first 90 minutes of a five-hour break,half of the participants were required to stay awake while half were told to sleep.Participants who stayed awake were asked to describe their thoughts.Participants who slept were asked to describe any dream they had.
Stickgold and his colleagues wanted to know about NREM,or non-REM sleep.REM stands for"rapid eye movement",which is what happens during REM sleep.This period of sleep often brings strange dreams to a sleeper,although dreams can happen in both kinds of sleep.Stickgold wanted to know what people were dreaming about when their eyes weren't moving,during NREM sleep.Other studies have found a connection between NREM bring activity and learning ability.
Four of the 50 people who slept said their dreams were about the maze.Later,when these four people tried the computer maze again,they were able to complete it faster.
Stickgold believes the dream itself doesn;t help a person learn---it's the other way around.He suspects that such dreams are caused by the brain processes associated with learning.
All the maze-dreamers had done the task poorly the first time,which makes Stickgold wonder if the NREM dreams show up when a person finds a new task particularly difficult.People who had other dreams,or people didn't sleep,didn't show the same improvement.
 
36.In the first stage of the study,the participants were asked toB
A.design a maze on computer
B.find their way out of a maze
C.decide where to begin a maze
D.remember a location in a maze
37.What happened to the participants during the break?D
A.Half of them were woken up when they started to dream.
B.Half of them were asked to dram about the maze.
C.All of them were asked to describe their thoughts.
D.Half of them were asked to sleep for 90 minutes.
38.What can we learn from the passage?D
A.Everyone will dream about a new skill after learning it.
B.Stickgold was the first to study dreams and learning.
C.During NREM sleep,people usually don't dream.
D.Unusual dreams often occur during REM sleep.
39.In the first stage of the study,the participants were asked toB
A.design a maze on computer
B.find their way out of a maze
C.decide where to begin a maze
D.remember a location in a maze
40.Which of the following statement best summarizes the study's conclusion?A
A.Dreams have a role in learning.
B.Dreams have no basis in reality.
C.Dreams are important for health.
D.Dreams are the best way to study.
