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．

分析 這是一篇科普文．研究人員發(fā)現(xiàn)，同時(shí)做很多事情的人做事不專一，不僅會(huì)導(dǎo)致事倍功半，而且還會(huì)影響人們的社交與情感健康．

解答 29-32 DBCA
29 D 細(xì)節(jié)理解題．根據(jù)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．比如在數(shù)字化的世界里做生意（doing business in the digital world）是無害的，因此選D．文章說同時(shí)做很多事會(huì)影響我們?cè)谌穗H交往和情感方面的健康（A錯(cuò)），會(huì)使我們記性更差（B錯(cuò)），一位叫Todd的作家說這樣可能會(huì)使我們失去未來一代偉大的思想家（C錯(cuò)）．
30 B 推理判斷題．根據(jù)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．歡迎來到同時(shí)做很多事的世界，在這里，對(duì)一個(gè)人的衡量標(biāo)準(zhǔn)是他能同時(shí)開展多少項(xiàng)工作，這個(gè)想法實(shí)際上害人不淺，因此B項(xiàng)正確；從第二段可知A、C錯(cuò)，因?yàn)閙ultitasking有時(shí)是無害的，有時(shí)則會(huì)妨礙我們；第二段最后一句通過打比方的方式告訴我們，這樣會(huì)使事情做得更慢（D錯(cuò)）．
31 C 推理判斷題．從本題四個(gè)選項(xiàng)的陳述看，A、B、D都是專心在做一件事，C項(xiàng)說辦公桌上放著各種沒有完工的項(xiàng)目的文書工作，這里的various unfinished projects屬于multitasking．故選C．
32 A 主旨大意題．全文通過斯坦福大學(xué)一位教授的話告訴我們，同時(shí)做很多事不僅不能提高工作效率，反而對(duì)我們的健康不利，因此A項(xiàng)"角色轉(zhuǎn)換越少，做的就越好"是本文的主題．故選A．

點(diǎn)評(píng) 本文是政治經(jīng)濟(jì)類閱讀理解．做這類題材閱讀理解時(shí)要求考生對(duì)文章通讀一遍，做題時(shí)結(jié)合原文和題目有針對(duì)性的找出相關(guān)語句進(jìn)行仔細(xì)分析，結(jié)合選項(xiàng)選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測(cè)，一定要做到有理有據(jù)．

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(fèi)）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．

8．From now on，never spend your precious time thinking of reasons for your failures and shortcomings．Instead，realize that the seeds of success were planted within you when you were born．Only you have the power to make those seeds grow．
The seeds，and the power to grow them，are contained in the best machine ever created：the human mind．Success is a choice and not a chance．You were born a winner．You can be a success if only you make the right choice．
You cannot be successful without first developing your self-esteem（自尊）．Your level of self-esteem is always based on the degree of control that you are able to have over yourself，and thus over your life．People with low self-esteem are people who do not believe that they have any power，or responsibility for their lives．They are leaves tossed（搖擺） by the winds of chance blown about with any sudden change in the weather．
You can control your life only to the degree that you believe that you are responsible for everything that happens in your life．Failures think that everything happens by accident and chance．Successful people realize that they are responsible．
Everything happens as a result of something．If we can identify the cause，we can control the effect．We are responsible for what we choose to think and believe．One generally rises to the level that one expects．We are responsible for setting our expectations．Our success is dependent upon our level of confidence．
In short，in all areas of your life，whether they are financial，physical，emotional，or spiritual，you are responsible．Once you recognize this，accept it，and firmly believe it，you are on the road to success．
68．People with low self-esteem are compared to leaves because theyD．
A．a(chǎn)re easily affected by windy weather             
B．a(chǎn)re ready to change their minds
C．don't have the power to face their fate            
D．can't control themselves
69．Losers would think thatA．
A．their failure is only because of bad luck           
B．they don't make efforts to succeed
C．working hard will lead to success             
D．success is the result of hard work
70．It can be inferred from paragraph 5 thatB．
A．success is a chance
B．We are what we make us
C．thoughts and beliefs are the result of creative mind
D．developing confidence is the only way to future success
71．The last paragraph serves asC．
A．the proof of the author's points                    
B．a(chǎn)n introduction to another topic  
C．the conclusion of the argument                     
D．a(chǎn) comparison between two views．

9．What parents owe their children？
I take the firm position that parents do not owe their children a college education．If they can afford it，they can certainly send them to the best universities．But they must not feel guilty if they can't If the children really want to go，they'll find away．There are plenty of loans and scholarships for the bright and eager ones who can't afford to pay．
When children grow up and want to get married  their parents do not owe them a down payment on a  house．They do not have the duty to baby-sit their grandchildren If they want to do it must be considered  a favor not an obligation．
Do parents owe their children anything？Yes，they owe them a great deal．
One of their obligation is to give their children a personal worth．A child who is constantly made to feel stupid and unworthy．constantly compared with brighter brothers，sisters，or cousins will become so unsure，so he/she is afraid of failing that he/she won't try at all．Of course they should be properly corrected  when they do wrong，but it's often better to let children learn their mistakes by themselves in time．All our parents should do is to trust them  respect them，tolerate them and give them chances to try and fail．They must learn to stand failure．When criticisms are really needed，they should be balanced with a smile and a
Kiss．That is the way children learn．
Parents owe their children a set of solid values to build their lives．This means teaching them to respect the rights and opinions of others； it means being respectful to elders，to teachers，and to the law The best way to teach such values is by deeds．A child who sees no laughter and no love at home will have difficulty in laughing and loving．
No child asks to be born．If you bring  a life into the world，you owe the child something．

50．According to the author，C．
A．parents must support their children even after they married
B．parents should give their children a down payment on a house
C．parents needn't feel guilty if they are unable to send their children to universities
D．if parents can't afford the tuition，they should take loans to send their children to go to colleges
51．The author mainly talks about in this passageA．
A．the duties of the parents
B．why parents owe their children something
C．the best way for parents to teach their children
D．the reason why children feel stupid and unworthy
52．According to the author，what should parents do when children make mistakes？C
A．Criticize and correct them immediately．
B．Compare them with brighter brothers or sisters．
C．Let'children learn their mistakes by themselves in time．
D．Tolerate them and tell their children not to mistakes again．
