The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keyboard or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compared unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.
It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular(微蜂窝,微孔的) level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.
Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 percent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.
The effects on IQ were studied by Dr. Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”
小题1:We can learn from the passage that “infomania” __________.
A.has a positive influence on one’s IQ
B.results in the change of part of the brain
C.lies in the problem of lack of concentration
D.is caused by too much use of modern technology

Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials.
The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012.
Online versions(版本) are now available for many of the most popular college textbooks. An e­textbook can cost half the price of a new print textbook. But students usually lose access to them after the end of the term. And the books cannot be placed on more than one device(设备),so they are not easy to share.
So what do students think of e­textbooks?Administrators at Northwest Missouri State University wanted to find it out. Earlier this year they tested them with 500 students in 20 classes.
The university is unusual. It provides laptop computers for all 7,000 of its full­time students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to e­textbooks.
The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And 56% said they were better able to find information.
But most found that using e­textbooks did not change their study habits. And 60% felt they read more when they were reading on paper. In all,almost half the students said they still liked physical textbooks better.
But the survey found that cost could be a big influence.55% said they would choose e­textbooks if using them meant their textbook rental fee would not increase.
Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State University. He tells us that administrators are disappointed with the e­textbooks now available because the majority are not interactive(交互式的).
He thinks growth will come when more digital books include video,activities,games and other ways to interact with the information. The technology is improving. But for now,most of the books are just words on a screen.
小题1:E­textbooks are not better than paper books in that________.
A.they cost more money
B.they’re difficult to carry
C.they’re not convenient to share
D.they can’t be downloaded from the Internet
小题2:How many surveyed students think paper books make better reading?
A.60%.B.56%.C.55%.D.50%.
小题3:It can be inferred from the text that in the future________.
A.digital books will be more popular
B.the digital books available need improvement
C.free digital books are available online
D.digital books will replace print textbooks

Many drivers say the large digital billboards flashing ads every few seconds along Bay Area freeways are just too bright and too distracting. And they may be right.
A Swedish study published in the journal Traffic Injury Prevention concludes that digital billboards hold the gazes of drivers longer than two seconds. Previous studies have shown that anything that takes a driver’s eyes off the road for that length of time increases the risks of a crash. “This study proves what is common sense when it comes to digital billboards,” says Mary Tracy, president of Scenic America, a national nonprofit group that seeks to limit billboards. “Bright, constantly changing signs on the sides of roads are meant to attract and keep the attention of drivers, and this study confirms that this is exactly what they do.”
The Federal Highway Administration allowed digital signs for the first time in 2007 after concluding they did not pose a significant danger. But a follow-up report is pending (待定的) and could be released this year. California has no law banning the billboards, and is one of 39 states that allows them. “We would need to review more research, so it’s too early to call for a ban,” says Jonathan Adkins, executive director of the Governors Highway Safety Association. “There is a role for digital messaging, such as conveying urgent information and other safety messages.”
There are more than 1,800 digital billboards nationwide, more than double the number five years ago. While no data indicate an increase in accidents due to the Bay Area signs, many drivers are opposed to them.
“Monstrosities” is what Merlin Dorfman of San Jose calls them, while insurance agent David Whitlock says he has found them a major distraction. “They’re much too bright at night,” he says. “When the advertisement switches from a bright color to a darker one, your eyes cannot adjust fast enough, and you end up losing sight of the roadway.”
Officials with sign companies could not be reached for comment, but Bryan Parker, an executive vice president for Clear Channel Outdoor, told USA Today last year that “there’s no doubt in my mind that they are not a driving distraction.”
小题1:Which of the following is TRUE?
A.The brightness of digital billboards is harmful to people’s eyes.
B.The Federal Highway Administration banned digital signs in 2013.
C.There is evidence indicating an increase in accidents duo to digital billboards.
D.Digital billboards are used to convey messages.
小题2:What do we learn from the text?
A.Scenic America is an organization that is in favor of digital billboards.
B.Drivers in the Bay Area are against the digital billboards.
C.California has banned digital billboards.
D.There were about 1,800 digital billboards nationwide five years ago.
小题3:What is Bryan Parker’s attitude towards digital billboards?
A.Supportive.B.Indifferent.
C.Opposed.D.Uncertain.
小题4:What is the main idea of the text?
A.Studies have shown digital billboards pose a danger to drivers.
B.People’s eyes cannot adjust fast enough to the brightness of digital billboards.
C.A study says flashing digital billboards are too distracting.
D.Experts doubt it is necessary to limit digital billboards.
小题5:We are most likely to find the text in the ________ section of a magazine.
A.international cultureB.traffic and safety

While you may be doing everything right, ignoring just one or two steps in the process may keep you from getting a job, especially in this fierce market. Here is a checklist that covers some of the major links in the job-search chain.
THE RESUME --- Make sure it is up-to-date and tailored to the types of jobs you are seeking for. Have someone else look at your resume. If you cannot afford a career coach, give your resume to friends or family members to scrutinize. Have copies of your resume printed so that you are ready to hand them out at interviews.
COVERING LETTERS --- Maybe you’ve set up a few basic styles in advance, but that’s not enough. Each covering letter should be designed to suit the job for which you are applying.
THE WARDROBE(衣橱) --- Check your wardrobe to ensure that you have the appropriate professional dress, including shoes, ready for interview.
NETWORKING --- Don’t isolate yourself from others for days. Network through e-mail messages, phone calls, appointments and meetings keep you in touch with the outside world and prevent you from becoming depressed.
APPLICATION --- A glance at huge online job sites isn’t usually the best way to find a job. You are more likely to succeed through the people you know via networking.
THE FOLLOW—UP --- It is quite common to apply for job and never hear back from the company. Take measures, such as following up with a phone call a week or so after you apply. If you know someone at the company, check whether that person will put in a good word for you.
INTERVIEWS --- If you’ve got plenty of interviews but no return calls or job offers, take a look at your interviewing skills. This is one area where investing in a career coach may pay off. But if you can’t afford one, try to find a job group or service that conducts free mock(模拟) interviews.
SUPPORT SYSTEMS --- Finally, recognize that looking for job is rather difficult. Even at the best of times, a job hunt is often about rejection, and that can be hard to endure. Staying in touch with family, friends, professional networks and fellow job seekers can help you to maintain a positive attitude and a sense of perspective.
小题1:The author’s purpose of writing this text is to _________.
A.suggest graduates should find suitable jobs
B.tell people how to improve their interview skills
C.teach people how to get ready for an interview
D.give people some tips on searching for jobs
小题2:The underlined word “scrutinize” in Paragraph 2 can be replaced by ________.
A.checkB.useC.rewriteD.criticize
小题3:Which of the following methods is wrong according to the text?
A.You should have your resume read by your friends after finishing it.
B.You should create different covering letters for the different jobs you apply for.
C.Searching online is the most effective way to look for a job.
D.You should wear professional clothes and shoes for the interview.
小题4:What should you do if you don’t receive any calls after lots of interviews?
A.Ask a fellow job seeker to help you
B.Carefully review your interviewing skills.
C.Rewrite your resume as soon as possible
D.Go to the managers’ offices to find out why.
小题5: It is implied in the text that__________.
A.people often pay no attention to writing their resume
B.the interview is the most difficult step for interviewees
C.your social network may help you a lot in your job hunt
D.a career coach often offers free mock interviews to interviewees

Amusement parks make most of their money from admission fees paid by guests attending the park. Other sources include parking fees, food and drink sales and souvenirs. Practically all amusement parks operate using one of two admission principles:
Pay-as-you-go In this form, a guest enters the park at little or no charge. The guest must then buy rides one by one, either at the attraction’s entrance or by buying ride tickets. The cost of the attraction is often based on its complexity (复杂性) or popularity. The park may allow guests to buy unlimited admissions to all attractions within the park. A pass is then shown at the attraction entrance to gain admission.
Disneyland opened in 1955 using the pay-as-you-go form. Initially, guests paid the ride admission fees at the attractions. Soon, the problems of dealing with so many coins led to the development of a ticket system that, while now out of use, is still part of the amusement-park vocabulary. In this new form, guests bought ticket books that contained a number of tickets, with “A,” “B” and “C.” Rides and attractions using an “A-ticket” were generally simple, with “B-tickets” and “C-tickets” used for the larger, more popular rides. Later, the “D-ticket” was added, then finally the now-famous “E-ticket,” which was used for the biggest rides, like Space Mountain. Smaller tickets could be traded up for use on larger rides. Disneyland, as well as the Magic Kingdom at Walt Disney World, gave up this practice in 1982.
The advantages include:
guests pay for only what they choose to experience
attraction costs can be changed easily
The disadvantages include:
guests may get tired of spending money almost continuously
guests may not spend as much on food or souvenirs
小题1:What is the passage mainly about?
A.Attractions of amusement parks
B.Admission fees of amusement parks.
C.Admission principles of amusement parks
D.Sources of income of amusement parks.
小题2:According to the pay-as-you-go principle, guests _____.
A.don’t pay at the gate of the park
B.must pay for each ride they take
C.have to pay for all rides in the park
D.needn’t pay after entering the park
小题3:According to the passage, what is the meaning of the underlined word “Initially” in Paragraph 3?
A.Gradually.B.At the beginning.C.At last.D.Commonly.
小题4:What would be introduced following the passage?
A.The other admission principle
B.Amusement parks’ earnings.
C.Some other admission principles
D.Users of the pay-as-you-go principle.

The world is filled with smart, talented, educated and gifted people.We meet them every day A few days ago, my car was not running well.I pulled it in to a garage and the young mechanic had it fixed in just a few minutes.He knew what was wrong by simply listening to the engine.I was amazed.The sad truth is that great talent is not enough.
 I am constantly shocked at how little talented people earn. I heard the other day that less than 5 percent of Americans earn more than $100,000 a year. A business consultant who specializes in1 the medical trade was telling me how many doctors and dentists struggle financially. It was this business consultant who gave me the phrase, “They are one skill away from great wealth.”
There is an old saying that goes, "Job means 'just over broke(破产)’".And unfortunately, I would say that the saying applies to millions of people.Because schools do not think financial intelligence is intelligence, most workers "live within their means".They work and they pay the bills.Instead I recommend to young people to seek work for what they will learn, more than what they will earn.
When I ask the classes I teach, “How many of you can cook a better hamburger than McDonald's?” almost all the students raise their hands. I then ask, “So if most of you can cook a better hamburger, how come McDonald's makes more money than you?” The answer is obvious: McDonald's is excellent at business systems. The world is filled with talented poor people. They focus on perfecting their skills at building a better hamburger rather than the skills of selling and delivering the hamburger.
小题1:The author mentions the mechanic in the first paragraph to show that      
A.he is just one of the talented people
B.he is ready to help others
C.he has a sharp sense of hearing
D.he knows little about car repairing
小题2:The underlined part in the third paragraph can be best replaced by____   
A.spend more than they can afford
B.do in their own way
C.1ive in their own circle
D.1ive within what they earn
小题3:Why do talented people earn so little according to the author?
A.They don’t work hard enough
B.They lack financial intelligence.
C.They don't make full use of their talents
D.They have no specialized skills.
小题4:The main purpose of the author is to tell us____      
A.how young people can find a satisfactory job
B.What schools should teach about finance
C.why so many talented people are poor
D.how McDonald's makes much money

Pretending to be happy can actually make you more miserable — especially if you’re a woman, according to a new study.
The research found that women suffered more than men when pretending to be happy. Psychologist Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can backfire. He said, “Smiling for the sake of smiling can lead to emotional exhaustion, and that’s bad for the organization.”
Dr. Scott said the research showed customer-service workers who “fake smile” throughout the day worsen their mood and then withdraw from work, so their productivity drops. He added, “Bosses may think that getting their staff to smile is good for the organization, but that’s not necessarily the case.” Dr. Scott, assistant professor of management at Michigan State University, analyzed a group of bus drivers during a two- week period.
The study is one of the first of its kind to examine emotional displays over a period of time and compare the different effect that has on men and women. His team examined the effects of surface acting — or fake smiling — compared to what was termed “deep acting”, or cultivating(培养) positive emotions by recalling pleasant memories.
Dr. Scott said, “Women are harmed more by surface acting, meaning their mood worsens even more than the men and they withdraw more from work. However, they are helped more by deep acting, which means their mood improves more.”
Although “deep acting” seems to improve mood in the short-term, Dr. Scott said it’s not a long-term solution to feeling unhappy.
He said, “You’re trying to cultivate positive emotions, but at the end of the day you may not feel like yourself anymore.”
小题1:What does the underlined word “backfire” in Paragraph 2 probably mean?
A.Have the opposite effect.B.Lead to conflict.
C.Drive people mad.D.Help a lot.
小题2:What can we learn from the passage?
A.Surface acting is good for organizations.
B.Men benefit more from deep acting than women.
C.Fake smiling causes more harm to women than men.
D.Recalling good memories is a long-term solution to feeling down.
小题3:The findings of the research might serve as a warning to _______.
A.employeesB.employersC.researchersD.customers.
小题4: What would be the best title for the passage?
A.Solution to feeling unhappy
B.How to cultivate positive emotions
C.How to improve workers’ productivity
D.Fake smiling makes you miserable

Surgical teams accidentally leave clamps, sponges and other tools inside about 1,500 patients nationwide each year.
The mistakes largely result not from surgeon tiredness, but from the stress arising from emergencies or complications(并发症) discovered on the operating table, the researchers reported.
The study found that emergency operations are nine times more likely to lead to such mistakes, and operating–room complications requiring a change in procedure are four times more likely.
It also happens more often to fat patients, simply because there is more room inside them to lose equipment, according to the study.
Two–thirds of the mistakes happened even though the equipment was counted before and after the procedure, in keeping with the standard practice.
Most lost objects were sponges, but also included were metal clamps and electrodes(电极). In two cases, 11–inch retractors (牵引器) metal strips were forgotten inside patients. In another operation, four sponges were left inside someone. When there is significant bleeding and a sponge is placed in a patient, it can sometimes look indistinguishable from the tissue around it.
The lost objects usually lay around the abdomen (腹腔) or hips but sometimes in the chest. They often caused tears or infections. Most patients needed additional surgery to remove the object. In other cases, patients even sensed nothing about the object, and it turned up in later surgery for other problems.
To prevent such mistakes from happening, Loyola University Medical Center is becoming one of the first hospitals in the country to use sponges outfitted with bar codes. The new system was brought to Loyola through the efforts of the hospital’s operating room nurses.
Another effective way is to X–ray patients after surgery to reduce the likelihood of objects being left inside patients.
小题1:In which of the following situations are objects most likely to be left inside a patient?
A.The nurses are counting the equipment and the patient is being X–rayed.
B.The surgeons are doing the last operation of the day, and everyone is exhausted.
C.unexpected happens and some changes must be made in the procedure.
D.A complex operation is going on according to the plan made by many experts.
小题2:Which of the following statements is NOT true?
A.Such mistakes happen more often to fat patients.
B.1,500 patients suffer from the mistake all over the world every year.
C.X–ray examination can help to find the lost objects.
D.The mistake largely results from stress rather than tiredness.
小题3:What can we infer from the passage?
A.Surgical teams aren’t to blame for the mistakes.
B.Some people never know there is something left inside their body.
C.Most mistakes happen because equipment isn’t counted after the procedure.
D.Only some small objects may be left inside the patients.
小题4:What is the best title for the passage?
A.Never Trust AnyoneB.A Mistake in the Operating Room
C.Carelessness and MistakesD.Tips for Patient Safety
