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．

分析 文章的主題圍繞當(dāng)下很受歡迎的社交網(wǎng)站Facebook，揭露其將用戶資料出售給廣告商．而大多數(shù)用戶并未意識(shí)到這一點(diǎn)，因?yàn)樗麄儾]有意識(shí)到個(gè)人資料的重要性．作者的態(tài)度和立場(chǎng)非常鮮明，并表示考慮注銷自己的賬戶．

解答 31．答案 C 細(xì)節(jié)理解題．根據(jù)第一段Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages．臉譜網(wǎng)站在顧客不知情的情況下，通過(guò)把顧客的信息賣給廣告商來(lái)掙錢，故選C．
32．答案 B  細(xì)節(jié)理解題．根據(jù)第二段Most Facebook users don't realize this is happening．大多數(shù)臉譜網(wǎng)站的顧客并不知道或者不懂網(wǎng)站怎樣通過(guò)賣自己的信息來(lái)掙錢故選B
33．答案 A 細(xì)節(jié)理解題，根據(jù)第四段中"the company is simply making changes to improve its service，"可知，Elliot Schrage說(shuō)臉譜網(wǎng)站只是為了提高它的服務(wù)質(zhì)量．故選A
34．答案 C  細(xì)節(jié)理解題．根據(jù)倒數(shù)第二段中"He also urged the Federal Trade Commission to set guidelines for social-networking sites．"可知，Senator Charles Schumer主張給社交網(wǎng)站設(shè)置一些規(guī)章制度，故選C
35．答案 C 細(xì)節(jié)理解題．根據(jù)最后一段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．可知作者要取消自己在臉譜網(wǎng)站上的注冊(cè)是因?yàn)樗辉赴炎约旱男畔⒔唤o不讓人信任的人手里，認(rèn)為這樣代價(jià)太高，對(duì)個(gè)人信息泄漏這件事情不滿．故選C．

點(diǎn)評(píng) 1、要想做好科普英語(yǔ)閱讀理解題，同學(xué)們就要注意平時(shí)多讀科普知識(shí)類文章，學(xué)習(xí)科普知識(shí)，積累常見的科普詞匯，從根本上提高科普英語(yǔ)的閱讀能力．
2、要熟悉科普類文章的結(jié)構(gòu)特點(diǎn)．科普類文章一般由標(biāo)題（Head line），導(dǎo)語(yǔ)（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來(lái)看，這類閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語(yǔ)一般位于整篇文章的首段．背景交待一個(gè)事實(shí)的起因．主體則對(duì)導(dǎo)語(yǔ)概括的事實(shí)進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時(shí)，同學(xué)們要把這部分作為重點(diǎn)．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語(yǔ)相呼應(yīng)，命題者常在此要設(shè)計(jì)一道推理判斷題．　　
3、在進(jìn)行推理判斷時(shí)，同學(xué)們一定要以閱讀材料所提供的科學(xué)事實(shí)為依據(jù)，同時(shí)所得出的結(jié)論還應(yīng)符合基本的科普常識(shí)．

7．John was part of my childhood growing up in the 1970s and a link to sunny，fun-filled days spent on the beach at Bangor in the Northern Ireland where we went for our summer holidays．To many，he was a mystery．Every afternoon John would wander to the end of the pier（碼頭） where he fed the seagulls（海鷗）and delighted in the sound of their excited cries as they flew around his head．
Often I asked my family questions regarding John．Eventually I gave up as no one could tell me anything about him．As I grew up，my visit to the beach became less frequent，and my memories of John buried in a child's imagination．
Last year memories came flooding back as I walked along the coastline，where I noticed a lady feeding the seagulls on the pier，and I decided to introduce myself．Then I came to know that the lady was John's daughter，and after John left this world she carried out the ritual （慣例），which had held such importance for her father．
In some strange way I felt we shared a bond，each needing to remember．In return，Lucy told me of John's life，his days in the British Navy（海軍）during World War I and how he almost lost hope when his ship was attacked by a German U-boat in the North Sea and he found himself in a lifeboat with five others．
Close to death，he thought he heard the sound of wings．He put up his hands，only to catch a seagull that had landed on the side of the boat．The seagull saved the lives of the six men as it was used to catch fish，which kept them alive until they reached land．This period of John's life was one he never talked about．But the ritual he first performed as a young man remained a part of him until he died．
Now I visit Lucy as often as I can，just to chat or very often walk along the beach to the pier end．We enjoy the comfortable silence，each lost in special memories．
66．Seeing John feeding the seagulls，the author might feelC．
A．proud    B．worried      C．curious     D．guilty
67．Why did the author introduce herself to the lady？D
A．She wanted to make more friends．
B．She was also fond of feeding seagulls．
C．She was told the lady was John's daughter．
D．She was attracted by what the lady was doing．
68．John survived（從…中幸存下來(lái)） the attack because ofA．
A．a(chǎn) seagull  
B．a(chǎn) German U-boat
C．his daughter  
D．the British Navy
69．We can infer from the text that JohnB．
A．once served in both world wars
B．was a man with a grateful（感恩的）heart
C．spent all his life in Bangor
D．joined the navy in the 1970s
70．What does the author mainly tell us in the text？C
A．She expressed her thanks to a seagull that saved her life．
B．She told us the story of how she made friends with a lady．
C．She shared with us her memories of a man who fed seagulls．
D．She talked about her childhood spent on the beach at Bangor．

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．
25．The first two paragraphs are used toB．
A．blame Liz for not being responsible for her work
B．describe what schools are like in the 21st century
C．give an example of a successful school lesson
D．question whether it is right not to assign homework
26．The underlined sentence in Paragraph 3 means"some people may think it as a way ofA"
A．spoiling children                   
B．making children become lazy
C．leading children to make mistakes   
D．caring about children
27．Jan Olson thinks it important for students toC．
A．repeat the facts without really thinking
B．learn something related to technology
C．make full use of information
D．use technology to improve their grades
28．Which is the most effective way to help students achieve more？D
A．Assigning more homework             
B．Offering immediate answers．
C．Giving more pencil-and-paper tests
D．Holding more discussions with them．

5．Emotional Intelligence （EQ or EI） is a set of abilities or petencies that enable us to understand and manage ourselves and our emotions effectively．EQ also helps us understand and effectively relate to others．Stress tolerance，leadership，munication，social responsibility，problem solving and creativity all require high EQ．
Here are some of the major emotional intelligence competences that make up a fully integrated personality as well as a sample of a state of the art assessment that measures EQ．
Emotional Expression-The ability to express your feelings and instincts（本能）．Emotional expression is a necessary part of your day．
EmotionalA wareness of Others-The ability to hear，sense or intuit what other people may be feeling from their words，body language（not verbal） or other direct or indirect clues．
Flexibility-The ability to bounce back，be flexible，and retain curiosity and hope in the face of adversity，change or challenge．
Optimism-B eing positive and optimistic．
EQ is recognized to be one of the most important predictors of personal，business and professional success．In a world of unprecedented change and challenge it is our ability to increase our EQ that will help us build the leadership，transparent munication and collaboration to lead better lives，do better business and contribute to a better world．
IQ may get you the client，but your EQ skills will help you keep the client and build a growing practice．Why？B ecause，while human beings like to make their decisions m an intelligent way to purchase a product or a service，the bottom line remains that we buy services and products from those we trust and like．It is our ability to trust and like another person that makes us feel comfortable with the relationship and inspires the desire to have or to purchase something from them．
It is the human ability to put instincts，emotions and thoughts into the correct position in relation to each other that gives us the competence to increase our emotional intelligence．A nd it is the human ability to use the changes and challenges we face to develop self awareness and emotional management that helps us communicate better．
With appropriate education and training，Emotional Intelligence can be developed throughout our lives．Like most human competences，Emotional Intelligence is best increased in the learning and the doing，and that is why EQ focused coaching is so powerful

12．A dog's tail can tell you a lot more than you might think．Is it wagging（搖）to the left or is it wagging to the right？
"The direction of tail wagging does in fact matter，"said Giorgio Vallortigara，a professor at the University of Trento in Italy．Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog．
What's the difference between a left wag and a   right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds-German Shepherds，Beagles，Boxers，Border Collies and some mutts．They find that if a dog wags its tail to the left，it's feeling anxious or nervous．The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog．But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable．
"The tail is a very important signal，"said Thomas Reimchen，a biologist at the University of Victoria in British Columbia，Canada．"There is a lot of visual information that dogs use when communicating with each other．"
How did the scientists figure all this information out？They had the dogs in their study watch videotapes of other dogs．When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool．But when the dog on the tape wagged its tail to the left，the other dogs got anxious．
The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously．They suspect that it might be something the dog does without even thinking about it-kind of like when you get goose bumps if something scares or startles you．They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging．As Reimchen said，"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before．"
 
64．Professor Vallortigara'study focused on the relationship betweenB．
A．a(chǎn) dog's state of mind and its owner's feeling
B．a(chǎn) dog's state of mind and the direction of its tail wagging
C．a(chǎn) dog's sense of direction and its state of mind
D．a(chǎn) dog's intention of tail wagging and its feeling      
65．According to the study，dogs which wag their tails to the left may feelD．
A．calm        B．happy         C．a(chǎn)ngry         D．a(chǎn)nxious
66．It is implied in Thomas Reimchen's words in Paragraph 4 thatC．
A．dogs'tails play an important role in their growth
B．dogs show their feelings only by wagging their tails
C．dogs get to know others by watching tail wagging 
D．dogs can understand each other by repeating tail wagging
67．How does the passage mainly develop？A
A．By asking and analyzing questions       
B．By making comparisons．
C．By following the order of time．
D．By providing examples．

2．I remember my mother as a strong woman．She came to America when she was 12-old enough to remember her language，she achieved scores and grades high enough to be admitted to Duke University．With a degree in computer science，she finally became the manager of a company in New York．My mother could give fluent speeches，say"wolves"correctly．
It was my mother who always stressed the importance of language．From the time I was born，I was read to．I would fall asleep to the sounds of my parents'voices，whether it was my dad's softly accented，or my mother's clear English．The flow of language was unbroken，and whether in Chinese or English，the stream of communication flowed through our house．
One October morning in sixth grade，after my mother had left to catch the train to the city，I left the house for the bus stop．I was surprised when I saw our car，the door hanging open．As I drew closer，I saw my mother lying on the ground．
In the hospital，it was hard to believe that the lady who lay before me was my mom．My mother could not remember my name．As the leaves changed colors，it became clear that the stroke had created a wall between my mother's mind and mouth：her mind was not any less clear，but the words she spoke were not what she meant．
The battle my mother faced taught me the importance of language．Without it，identity does not exist； relationships cannot be formed； stories cannot be told； directions cannot be given，and knowing anything about anyone is impossible．Without language，communication cannot take place．Without language，one cannot express the beauty of a sunset or the kindness of a stranger．The world would pass us by in silence．

41．From where might the author's mom come to AmericaA？
A．China
B．England
C．Russia
D．Canada
42．From the second paragraph，we can knowD．
A．the author was taught to read since she was born
B．the author's father spoke English poorly
C．the author couldn't fall asleep without being read to
D．the author's parents taught her language by talking a lot
43．According to the last two paragraphs，the author's mom was unable toB．
A．think clearly
B．express herself well
C．speak
D．open her mouth
44．The underlined word"stroke"in the 4th paragraph most probably refers toC．
A．a(chǎn)n accident
B．a(chǎn) hit
C．a(chǎn)n illness        
D．a(chǎn) robbery
45．This passage is mainly aboutB．
A．a(chǎn) strong mother
B．the importance of language
C．a(chǎn) family disaster
D．the significance of teaching language．
