    (2013·高考广东卷，D)While Jennifer was at home taking an online exam for her business law class，a monitor(监控器)a few hundred miles away was watching her every move.
    Using a web camera equipped in Jennifer’s Los Angeles apartment，the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room.Her Internet access was locked－remotely－to prevent Internet searches，and her typing style was analyzed to make sure she was who she said she was：Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
    In the battle against cheating，this is the cutting_edge and a key to encourage honesty in the booming field of online education.The technology gives trust to the entire system，to the institution and to online education in general.Only with solid measures against cheating，experts say，can Internet universities show that their exams and diplomas are valid—that students haven’t just searched the Internet to get the right answers.
    Although online classes have existed for more than a decade，the concern over cheating has become sharper in the last year with the growth of“open online courses.”Private colleges，public universities and corporations are jumping into the online education field.spending millions of dollars to attract potential students，while also taking steps to help guarantee honesty at a distance.
    Aside from the web cameras，a number of other high­tech methods are becoming increasingly popular.Among them are programs that check students’ identities using personal information，such as the telephone numbers they once used.
    Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones.As in many university classes，term papers are scanned against some large Internet data banks for cheating.

    All Ric O Barry wants is to stop the dolphin­killing, so he is headed to this seaside Japanese town, Taiji.The American activist, who is the star of a new award­winning documentary that portrays the dolphin­killing here, got an unwelcome reception when he showed up here this week for the start of the annual hunt.
    His movie, The Cove(海豚湾), directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan.
    Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins— which have supersensitive sonar(声纳系统)—and sends them fleeing into a cove.
    There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150,000. They kill the others, spearing(刺) the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50,000 yen, and is sold at supermarkets across Japan.
    Greenpeace and other groups have tried to stop the hunt for years.Activists hope The Cove will bring the issue to more people internationally—and eventually in Japan.
    Already，the Australian town of Broome dropped its 28­year sister­city relationship with Taiji last month，partly because of the movie.
    “Some regions have a tradition of eating dolphin meat，” said fisheries official Toshinori Uoya. “Dolphin­killing may be negative for our international image, but it is not something orders can stop.”
    The town government in Taiji—which has made whales and dolphins its trademark—refused to comment about The Cove, or the growing international criticism against dolphin­killing.
    Many in Taiji take the dolphin hunt for granted as part of everyday life. They are defensive about The Cove，seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.
    小题1:Ric O Barry made The Cove because he wanted to ________.
    A．stop the dolphin­killing
    B．win an international award
    C．support Greenpeace's efforts
    D．make Taiji well­known in the world
    小题2:Viewers can learn from The Cove ________.
    A．the advanced techniques to catch dolphins
    B．the cruel and bloody dolphin­killing
    C．the beautiful Japanese seaside town Taiji
    D．the sale of dolphin meat around the world
    小题3:What is the response to The Cove on the Japanese side?
    A．Taiji broke up with its western sister­city Broome.
    B．Japanese officials decided to ban dolphin­killing.
    C．The town government in Taiji kept silent on criticism.
    D．Most Japanese people were against eating dolphin meat.
    小题4:What does the underlined word “defensive” probably mean?
    A．Feeling guilty for killing dolphins.
    B．Protecting themselves against criticism.
    C．Attacking those against dolphin­killing.
    D．Making the determination to change.
    小题5:What can we infer from the passage?
    A．Many people in Japan have seen The Cove in the cinema.
    B．The Cove has not influenced Japan's international image.
    C．Taiji's dolphin­killing industry has been seriously damaged.
    D．The Cove has brought international attention to dolphin­killing.

    When several people look at the same person, it is not unusual for each of them to see different things; when you are alone observing one behavior or a person at two different times, you may see different things. The followings are but some of the factors that lead to these varying perceptions(感知,认识):
    (1)    Each person’s perceptions of others are formed by his or her own cultural conditioning, education, and personal experiences.
    (2) Sometimes perceptions differ because of what we choose to observe and how we deal with what’ve observed. It is not necessarily true that person perception is based on observations of a particular person. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same standard to measure their parents, their friends, and strangers.
    (3) Sometimes we see only what we want to see or don’t see what may be obvious to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory information is particularly obvious, but it can be done. We can ignore the stimulus——“He’s basically a good boy so what I saw was not shoplifting(入店行窃).” We can reduce the importance of the contradictory information ——“All kids get into mischief(顽皮). Taking a book from a bookstore isn’t such a big deal.” We can change the meaning of the contradictory information--- “It wasn’t shoplifting because he was going to pay for it later.”…
    小题1:The first factor given by the author that affects our perception is _____.
    A．our hearing and visual abilities
    B．cultural background and personal experiences
    C．the experience one learns from others
    D．critical measures taken by other people
    小题2:While observing a particular person,________.
    A．one is likely to take all aspects into consideration
    B．one pays more attention to his/her advantages
    C．children often differ from grown-ups in perception
    D．one tends to choose certain aspects to look at
    小题3:Observation of the same person by two people at the same time may differ because _____.
    A．they follow different standards
    B．either of them may be slow to catch information
    C．the time for observation is not long enough
    D．each of them uses different language to express his/her impressions
    小题4: The underlined word “stimulus” in Paragraph 4 refers to _____.
    A．something attractive
    B．selective perception
    C．contradictory information
    D．shoplifting
    小题5:The worst thing in selective perception is that ______.
    A．the information received runs against your desire
    B．facts can be twisted or totally ignored
    C．importance of the contradictory information can be overrated (估计过高)
    D．misbehaved children may not be punished

    Where Are We Going, Dad? has become one of China's most popular television shows, since its debut (首次登场) in October, averaging more than 600 million viewers each week. Sponsorship rights (冠名权) for the show's second season were sold for 312 million yuan (about $ 50 million), more than ten times higher than the rights to the first season.
    What accounts for its popularity? The show features a new generation of Chinese fathers, who, as part of the country’s new middle class, have faced more problems with modern child-raising techniques such as taking an active role with their children.
    Part of the appeal of the show is the chance to throw a glance at the lives of Chinese celebrities (名流) and their children. Audiences are interested in watching the failed attempts of celebrity dads making dinner, doing hair, and disciplining (管教) children -- tasks often left to mothers in a society still influenced by the saying that “men rule outside and women are inside.” “In traditional Chinese culture, fathers are strict and mothers are kind. But on the show, we see fathers who are much gentler on their kids and more involved in their upbringing, ” said Li Minyi, an associate professor. “This show raises an important question for modern Chinese society -- what is the role of fathers in today’s China?”
    After each episode (集) goes to air, the Chinese internet explodes with comments on each celebrity's parenting style.
    Actor Guo Tao tries to communicate with his son, Shitou, but is seen as a more traditional Chinese father, and has been criticised online for being too harsh. Zhang Liang, a supermodel, is an audience favorite for treating his son, Tiantian, more like a friend. The show’s most famous celebrity, Lin Zhiying, a film star, was originally praised as patient with his son Kimi. But as the season progresses, fans begin to criticise him for raising a spoiled, undisciplined boy. Director Wang Yuelun is at a complete loss when it comes to care of his daughter’s hair.
    Even the People's Daily is pleased with the success of the show.
    小题1:Sponsorship rights for the show’s first season were sold for about______.
    A．312 million yuanB．50 million yuan
    C．31 million yuanD．600 million yuan
    小题2:According to the passage, the show______.
    A．gives audiences the chance to raise the star's children themselves
    B．invites some famous film stars to take part in it
    C．lets people think about the role of fathers in modern families
    D．raises people's concern about women's role in the society
    小题3:The underlined word “harsh" in the fifth paragraph most probably means “______”.
    A．carelessB．strictC．clumsyD．kind
    小题4:According to the writer, ______is the most successful father.
    A．Guo TaoB．Zhang Liang C．Lin ZhiyingD．Wang Yuelun

    It’s really true what people say about English politeness: it’s everywhere. When squeezing  past someone in a narrow passage, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles, and here are some more polite ways of interacting  with people in UK.
    People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.
    Another thing I observed during my stay was that English people rarely criticize others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter are a bit tightfisted.
    小题1:What is the author’s attitude towards English politeness?
    A．He thinks it is unnecessary.B．He thinks little of it.
    C．He appreciates it very much.D．He thinks it goes too far.
    小题2:What can be inferred from the passage?
    A．German men never treat a woman to dinner.
    B．The author think it’s unnecessary to say “thank you” to the bus driver.
    C．In Germany, employers often say “thank you” to employees for their job.
    D．Germans think it is unnecessary to thank workers because payment is enough.
    小题3:We can learn from the last paragraph that Scottish men ______.
    A．like to fight with each other
    B．treat women in a polite way
    C．are as generous as English men
    D．are unwilling to spend money for women
    小题4:The author develops the text through the method of ______.
    A．making comparisonsB．telling storiesC．giving reasonsD．giving examples

    I have nothing to say about whether or not “A Day Without Immigrants(移民)” had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others.
    Regardless of how you feel about the event, one conclusion is obvious. Using the theme of “A Day Without” as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public consciousness about other issues that affect daily life in America. Here are my top three examples:
    “A Day Without Speeding.” How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge.
    “A Day Without Losing Your Temper.” A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but bursting into anger usually has nothing to do with the approach to the heart of the matter.
    “A Day Without Having All The Answers.” I would like to get a break from hearing anyone speak the phrase, “Here’s what you’re doing wrong.” Right now the US is packed with citizens who believe they can point out the cause of every single problem in existence and then solve it in a moment. I believe they need to be quiet sometimes and use their ears instead of their voices.
    I wonder how would average Americans react to such a national pause? Would it be a day of reaction against anger, or joyful celebrations?
    小题1:The first paragraph suggests ________.
    A．the writer is against “A Day Without Immigrants”
    B．immigrants are not equally treated by the US government
    C．the immigrants issue is so complex that the author has to refer to others
    D．some move to America without the permission of the US government
    小题2:The author uses his “top three examples” to________.
    A．criticize the undocumented illegal immigrants in America
    B．show public consciousness of some subjects could be raised
    C．encourage common people to create more similar activities
    D．indicate some bothering issues affecting people’s daily life
    小题3:According to the author, losing one’s temper is ________.
    A．unpleasant B．pointlessC．relaxingD．personal
    小题4:The writer suggests “a day without having all the answers”, because ________.
    A．he thinks the Americans are too proud
    B．he wants to have a chance to speak his mind
    C．he expects others to keep quiet and calm
    D．he hopes to get a break from the problems

    A survey reveals that employees in China say they are not engaged in their jobs. Judging by the survey data, many Chinese workplaces are black holes of misery and despair.
    Only 6% of Chinese employees said they are "engaged" in their jobs, according to a global Gallup survey released this month. China's numbers equal the numbers out of war-weary（厌战的） Iraq.
    Workers across all income levels and industries were surveyed by Gallup in China, defined by Gallup to mean they were "psychologically committed to their jobs and likely to be making positive contributions to their organizations".
    Out of 94 countries polled, only six countries scored lower rates of job engagement than China, including Tunisia, Israel and Syria. Unsurprisingly, 0% of Syrians admitted to being engaged at work.
    In a related survey, China ranked near the bottom in a poll measuring job satisfaction among 22 Asian countries. Only 49% of Chinese respondents said they were happy in their jobs.
    Part of the problem, I suspect, is that very few in China have the luxury to pursue a career that truly interests them.
    Even university graduates often feel they have no choice but to choose the positions with the government or state-run enterprises, since those jobs are thought to be stable.
    That makes those who are happy at work in China a rare find indeed.
    小题1:What can we infer from Paragraph 4?
    A．The people in Israel are not engaged in their jobs.
    B．People in Syria are more engaged at work than the Chinese.
    C．Most Chinese people are happy in work.
    D．China ranked the top in the job engagement.
    小题2:What is the meaning of the underlined word “luxury” in Paragraph 6?
    A．happinessB．dreamC．willingD．courage
    小题3:According to the author, why most Chinese dislike their jobs?
    A．Because they don’t take the jobs they really like
    B．Because many Chinese workplaces are full of misery and despair.
    C．Because they have no choice but to choose the stable jobs.
    D．Because they are not psychologically committed to their jobs.
    小题4:Which of the following jobs are the university graduates nowadays more likely to choose?
    A．LawyersB．Civil Servants (公务员)
    C．self-made menD．Doctors

    The traditional distinction between products that satisfy needs and those that satisfy wants is no longer adequate to describe classes of products. In today’s prosperous societies, the distinction has become unclear because so many wants have been turned into needs. A writer, for instance, can work with paper and pencils. These are legal needs for the task. But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want.
    In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main classes are convenience goods and shopping goods. Two lesser types are specialty goods and unsought(主动提供的) goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France (wine, for example) should be a specialty goods in the United States.
    People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae(圣代) on a hot day. Or they may be purchased as emergency items.
    Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores before making a decision. Buying an automobile is often done this way.
    Shopping goods fall into two classes; those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially different include clothing, furniture, and dishes. Quality, style and fashion will either take precedence(优先) over price, or they will not matter at all.
    小题1:It can be learned from the first paragraph that ______. 
    A．a writer needs a word processor
    B．needs and wants can’t be separated clearly
    C．the way to distinguish the products is unimportant
    D．a computer is a need rather than a want
    小题2:The example of wine is used to illustrate that ______.
    A．goods are classified differently in different countries
    B．the types of the product lie on the people rather than its nature
    C．Frenchmen often drink but Americans sometimes do
    D．one product may belong to many types
    小题3:Staples are items that ______.  
    A．are convenient to purchase
    B．are purchased without enough thinking
    C．people “want but don’t need”
    D．people are in constant need of
    小题4:Shopping goods that are considered as basically the same are those that ______.   
    A．consumers don’t care where to buy them
    B．consumers spend much time searching for
    C．satisfy similar needs of the consumer
    D．can be found in nearly every shop
