Turns out we aren’t good at walking and talking at the same time, according to a study of pedestrians （行人） on their cell phones．
Nearly one-third of pedestrians （29．8% ） were distracted （分散注意力） by their mobile  devices while crossing the street, say researchers of a study published online in the journal Injury Prevention．
Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident．
During the summer of 2012, scientists in Seattle, Wash． , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years．
They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so．Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person．
Overall, researchers found the most common distraction among pedestrians was listening to music （11．2%）, followed by text messaging （7．3%）, and using a handheld phone（6．2%）． But the most absorbing distraction was texting． Compared to pedestrians who were not distracted, those who were texting took 1．87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk． While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street．
Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians． And that danger may only climb, as the number of wireless devices has already exceeded the population of the United States． Last year, roughly 1,152 people wound up in the emergency room to treat injuries caused by using a cell phone or electronic device, the Consumer Product Safety Commission told the Associated Press in July． Those numbers may be underestimated, however, because patients may not always admit that they were using their phones along with other activities such as walking or driving when they were hurt．
小題1:The scientists did their study at the 20 crossroads in order to _____．
A．a(chǎn)ttract more attentionB．see more injuries
C．record more samplesD．find more pedestrians
小題2:According to the research, while crossing the street the most dangerous activity for apedestrian is _____．

This is an open letter to the three people who stole my handbag from the department store where I am employed as a shop assistant.
When you took my bag, I don’t know what you thought you were going to get. With my wages, there's not much left on a Tuesday. I hope the ￡5 was useful to you. If you really need a couple of pounds, I suppose you could always cash one of the two checks left in my check book. Of course, I phoned the bank right away and the check-cashing card is no longer valid, so it won’t be of much use to you.
Actually I don’t care about the money too much. We single parents who work to support our families understand only too well what it means to be short of cash. However, I don’t suppose it went very far among the three of you. Sorry about that!
I wish you had left the bag behind and just taken the wallet and check book. There were all kinds of papers and notes that I really need. I really think that was very inconsiderate of you. I mean, how would you like something like that to happen to you?
Well, perhaps the bag will turn up. It wasn’t even an expensive one, just a plain, old brown leather shoulder bag. You probably threw it in the nearest rubbish bin or threw it into the bushes. We've looked around, of course, but no one saw which way you went after you left the shop.
I'm not really angry with you. I know how the pressures of modern life can affect us, but I am sad at the loss of my personal things. I feel helpless. The police were very icy, and they just shrugged their shoulders. “It happens all the time,” they told me. Some small comfort, I suppose. But I’ve lost just a little more faith in human nature. And as my young son said when I told him what had happened, “Why? Mummy, why us?” I couldn't answer that question. I wonder if you can.
小題1: In writing Paragraph 2, the writer wants to           .
A．describe the contents of the bag in detail
B．tell the thieves hardly any money was available
C．state the fact that she was careless with the money
D．give some suggestions to the three thieves
小題2:Which of the following is the most valuable to the writer?
A．The cash in her bag.
B．The handbag itself.
C．The papers and notes in the bag.
D．The check book in the bag.
小題3:What can we conclude about the police?
A．They are unable to find the thieves.
B．They show sympathy to the woman.
C．They have doubts about human nature.
D．They think the case quite common.
小題4: Why does the author write the letter?
A．To give the thieves a serious warning.
B．To express her affection for her valuable bag.
C．To call people’s attention to their belongings.
D．To complain about the fall of morality.

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants居民of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the well-being (health and happiness) of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals航空集散站, first-class roads and other support facilities needed by tourist attractions. For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many support facilities設(shè)施as well, including roads to get to the hotel, electricity, sewers下水道to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.
小題1: Which of the following has most probably been discussed in the paragraph that goes before the passage?
A．It is extremely important to develop tourism.
B．Building roads and hotels is essential.
C．Support facilities are highly necessary.
D．Planning is of great importance to tourism.
小題2:Too much tourism can cause all these problems EXCEPT
A．a(chǎn) bad impact on other industries
B．a(chǎn) change of tourists’ customs
C．over crowded of places of interest
D．pressure on traffic
小題3:Not enough tourism can lead to
A．a(chǎn)n increase of unemployment
B．a(chǎn) decrease in tourist attractions
C．the higher cost of support facilities
D．a(chǎn) rise in price and a fall in pay
小題4:It is good for local people to be well aware that tourism will
A．use up large amount of water
B．weaken their economy
C．help establish their traditions
D．help improve their life

“Image is everything.” An entire industry has been built upon the assumption that image is everything, but when it comes down to it, an appealing image is not enough. If there is no substance（事實(shí)）behind the image, the product, service or person will fail eventually.
First of all, one should consider how important image is in the selling of products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. Public concept of that product or service is certainly managed by the images created by the advertising agencies．But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back. For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness. But the recent scandal (丑聞) showed that behind that image, it cheated in business practices. Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit. Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm.
Similarly, personal advisers can build up a public image for politicians and movie stars. Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons. But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close.
To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation. What lies behind that image is every bit as important as the image itself —— the person or product must deliver on that image or there is little chance for long-term success.
小題1:The downfall of the Arthour Andersen accounting firm is due to ___________.
A．its dishonesty in businessB．its previous images
C．its bad managementD．its poor service
小題2:Why did some famous people fall from grace?
A．Their images were not well built up.
B．They failed to live up to their images.
C．They felt much pressure from the public.
D．They paid little attention to fame and fortune.
小題3:The structure of the passage is ___________.
A: Argument   P: Point   C: Conclusion

小題4:The author tries to argue that ___________.
A．image creates everything
B．image is the key to success.
C．truth is unlikely ever to be equaled
D．truth and image are equally important

You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (禮儀) is sort of odd (奇怪的),” Gray told the BBC. “They [elevators] are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (對(duì)角線(xiàn)地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the  Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.
小題1:The main purpose of the article is to _____.
A．remind us to enjoy ourselves in the elevator
B．tell us some unwritten rules of elevator etiquette
C．share an interesting but awkward elevator ride
D．a(chǎn)nalyze what makes people feel awkward in an elevator
小題2:According to Gray, when people enter an elevator, they usually _____.
A．turn around and greet one another
B．look around or examine their phone
C．make eye contact with those in the elevator
D．try to keep a distance from other people
小題3:Which of the following describes how people usually stand when there are at least two people in an elevator?

小題4:The underlined phrase “size up” in Paragraph 7 is closest in meaning to _____.
A．judgeB．ignoreC．put up withD．make the best of
小題5:According to the article, people feel awkward in lifts because of _____.
A．someone’s odd behaviors
B．the lack of space
C．their unfamiliarity with one another
D．their eye contact with one another

“When I grow up, I want to be...”
Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.
However, it seems career options aren’t only based on personal taste. In a survey carried out by Teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the UK in May 2011 by job website monster. Co.uk, in which medicine was the top choice among UK teenagers aged between 13 and 17.
Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high-profile professions is often seen as a sign of upward social mobility.
It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the UK tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”.
However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens’ survey discovered, a variety of unconventional jobs---coffee shop owner, gourmet(美食家)，waiter at a fast food restaurant---are among teenagers’ career choices. They can be equally interesting and rewarding jobs.
With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.
小題1:What is the passage mainly about?
A．Careers in teenagers’ mind.
B．Choosing a good job is very important.
C．Teenagers in the UK like doctors.
D．The choice of career needs challenge.
小題2:What is the top career choice among UK teenagers aged between 13 and 17 according to the article?
A．MedicineB．LawC．BankD．Education
小題3:According to the article, all of the following are the benefits of being a doctor except_______.
A．respect from othersB．the oldest profession
C．high payD．upward social mobility.
小題4:What do youngsters think is increasingly becoming one of the most important indicators of a successful career?
A．PrestigeB．FulfillmentC．HappinessD．Wealth
小題5:What can we learn from the last paragraph?
A．According to your particular talents and skills, you can choose your favorite career.
B．Specific education and training can help get a good job.
C．Whatever career you choose, you should balance optimism and confidence with being realistic about your particular talents and skills.
D．Responsibility is the most important when you choose a good job.

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年癡呆癥）.
“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.
“Every ache and pain,” Smith suggested, “could be understood as the beginning of the end.” “That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”
Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.
小題1:Which of the following is true about James Watson？
A．He doesn’t want to know his chance of getting a disease.
B．He is strongly in favor of the present genetic tests.
C．He believes genetic mapping can help cure any disease.
D．He is more likely to suffer from Alzheimer’s disease.
小題2:The first paragraph is meant to__________.
A．a(chǎn)sk some questionsB．satisfy readers’ curiosity
C．introduce the topicD．describe an academic fact
小題3:According to Paragraphs 3 and 4, if a person is at a higher genetic risk, it is__________.
A．necessary to remove his anxietyB．impossible to hide his disease
C．better to inform him immediatelyD．a(chǎn)dvisable not to let him know
小題4:The underlined part “freak out” in Paragraph 5 is closest in meaning to“_________”.
A．leave offB．break downC．drop outD．turn away
小題5:The study led by Dr. Green indicates that people__________.
A．can accept some bad newsB．tend to find out the truth
