(2013·高考廣東卷，D)While Jennifer was at home taking an online exam for her business law class，a monitor(監(jiān)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.
【小題1】Why was Jennifer watched in an online exam?

A．To correct her typing mistakes.
B．To find her secrets in the room.
C．To prevent her from slowing down.
D．To keep her from dishonest behaviors.

Although Paris is often considered the city of romance, close to a million adults who call it home are single. Many single people say that France’s capital is one of the most difficult places to meet people. The complaints(抱怨) of this lonely group have inspired a new phenomenon known as “supermarket dating.” At Galerie Lafayette Gourmet, singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes, brown hair, and is 1.8 meters tall, or whatever may be on their romantic shopping list.
At this Paris location, single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door, they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles(過道) .
With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat.
Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish(美化) one’s appearance or to lie about one’s age over the Internet. The supermarket, on the other hand, is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another’s grocery basket can say a thing or two about that person’s character or intentions. Buying pet food can be a man’s way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These days it’s possible to find much more than food at a grocery store.
【小題1】What do many single people in Pairs complain about?

A．The difficulty in meeting people.
B．The idea of supermarket dating.
C．The items on their grocery list.
D．The inconvenience in shopping.
【小題2】Which of the following can be inferred but is not clearly stated in the second paragraph?
A．The dating supermarket is located in Paris.
B．The dating supermarket is open only on Thursday evenings.
C．People looking for love must get a basket of a particular colour
D．The dating supermarket has very good business.
【小題3】According to the writer, a possible way to win a woman’s heart is to _______.
A．pick up a purple basket
B．Buy low-fat food
C．embellish your appearance
D．buy pet food
【小題4】Why do the people prefer the supermarket dating to Internet dating?
A．The supermarket dating is more convenient.
B．The supermarket dating is more casual.
C．The supermarket dating can be trusted more.
D．The supermarket dating is less expensive.

Men are spending more and more time in the kitchen encouraged by celebrity (名人) chefs like Gordon Ramsay and Jamie Oliver, according to a report from Oxford University.
The effect of the celebrity role models, who have given cooking a more manly picture, has combined with a more general drive towards sexual equality and men now spend more than twice the amount of time preparing meals than they did in 1961.
According to the research by Prof. Jonatahn Gershuny, who runs the Centre for Time Research at Oxford, men now spend more than half an hour a day cooking, up from just 12 minutes a day in 1961.
Prof. Gershuny said, “The man in the kitchen is part of a much wider social trend. There has been 40 years of sexual equality, but there is another 40 years probably to come.”
Women, who a generation ago spent nearly two hours a day cooking, now spend just one hour and seven minutes—a great fall, but they still spend far more time in the kitchen than men.
Some experts have named these men in aprons as “Gastrosexuals (men using cooking skills to impress friends)”, who have been inspired to pick up a kitchen knife by the success of Ramsay, Oliver as well as other male celebrity chefs such as Hugh Fearnley-Whittingstall, Marco Pierre White and Keith Floyd.
“I was married in 1974. When my father came to visit me a few weeks later, I was wearing an apron when I opened the door. He laughed,” said Prof. Gershuny. “That would never happen now.”
Two-thirds of adults say that they come together to share at least three times a week, even if it is not necessarily around a kitchen or dining room table. Prof. Gershuny pointed out that the family meal was now rarely eaten by all of its members around a table—with many “family meals” in fact taken on the sofa in the sitting room, and shared by family members. “The family meal has changed a lot, and few of us eat—as I did when I was a child—at least two meals a day together as a family. But it has survived in a different format.” 
【小題1】What is one reason behind the trend that men spend more time cooking than before?

A．The improvement of cooks’ status.
B．The influence of popular female chefs.
C．The change of female’s view on cooking.
D．The development of sexual equality campaign.
【小題2】What does the author think about the time men and women spend on cooking?
A．Men spend more time cooking than women nowadays.
B．Women spend much less time on cooking than before.
C．It will take 40 years before men spend more time at the stove than women.
D．There is a sharp decline in the time men spend on cooking compared with 1961.
【小題3】How did Prof. Gershuny see the family meal according to the passage?
A．It has become a thing of the past.
B．It is very different from what it used to be.
C．It shouldn’t be advocated in modern times.
D．It is beneficial to the stability of the family.
【小題4】Which is the best title for the passage?
A．The Changes of Family Meals
B．Equality between Men and Women
C．Cooking into a New Trend for Men
D．Cooking—a Thing of the Past for Women

Parents are creating an “I want it now” generation by indulging children's every demand at Christmas，say experts.Youngsters are becoming increasingly selfish，claim the education analysts.
Consumer­savvy children are forcing their families into racking up huge debts and risk becoming spoilt and dissatisfied in the future.
Behavioural consultant Chris Calland said，“Parents are desperate to make Christmas into a magical fairy tale for their kids.There's nothing wrong with that as such.The problem arises when it means always giving in to all our children's demands—even if they are beyond our price range or not age­appropriate.”
Ms.Calland，who runs “Santa Says No” style sessions with colleague Nicky Hutchinson，added, “Many of us go into so much debt providing the gifts our children want that we spend the rest of the year paying off the bills.Yet so often the parcels we've carefully wrapped，once opened，are just pushed away because the very thing our little boy or girl was once so desperate for, they have now lost interest in.”
Ms. Calland and Ms.Hutchinson have drawn up a list of guidelines to help parents manage their offspring's Christmas lists this year.They say that adults can actually improve their relationships with their children by resisting “pester (糾纏) power”．
Ms.Calland said，“All too often we say yes because we want an easier life when the fact is that we're only building up problems for the future.We are helping create a generation of youngsters who are blind to the needs of others and the necessity of hard work.”
“Children learn fast—if we sometimes change our mind，they quickly realise it might be worth lying on the floor and screaming for it.Make sure you and your partner are working together on this.Be consistent.And try not to get caught up in competition with other families or friends.”
【小題1】How is the “I want it now” generation created?

A．Parents can't afford the gifts for their children.
B．Parents become heavily in debt.
C．Parents are trying to make Christmas into a magical fairy tale.
D．Parents give children whatever they want at Christmas.
【小題2】What is the main problem with the “I want it now” generation?
A．They are quite self­centered.
B．They like to live in fairy tales.
C．They waste a lot of money on gifts.
D．They can't keep their interest in gifts.
【小題3】What is probably the aim of “Santa Says No” style sessions?
A．To advise on how to wrap gifts properly.
B．To keep children's interest in the gifts.
C．To tell parents how to say no to children's demands.
D．To advise parents on what gifts to buy for children.
【小題4】According to the passage，we can infer that Ms.Calland intends to ________.
A．a(chǎn)nalyze children's behavior

A father in Wuhan, nicknamed "Eagle Dad" for his controversial parenting style, has dismissed critics' claims that he pushes his 4-year-old son too hard.
Police officer Wang Shaoyan came under the spotlight this month after his child took part in an 18-kilometer race in the Hubei provincial capital.
Some parents attacked his methods of extreme physical training, while others reacted strongly to his admission that he regularly exposes the youngster to cold showers. "I just want my son to reach his full potential," Wang said, adding that 4-year-old son not only runs 3 km every day he also takes cold showers from time to time to strengthen his body's resistance and willpower.
"He has never taken any sick leave from kindergarten," he said proudly. However, some parents find his methods too extreme.
"I'm not sure a 4-year-old is prepared for such intense training," said Zhang Ruxia  a woman who gave birth to two boys in October in Tianjin. "You can have good intentions to train your child at an early age but you also have to consider whether he can take it." Wang responded by saying children are too young to make decisions, and it is up to parents to lead them on the right path.
"I read many materials before and the whole process is step-by-step without pushing or imposing on my son," Wang said. The father said he was not acting rashly but following a scientific way of education. He said the doubts about his methods reflect the declining standards of modern education.
"Many people in Japan give their children cold showers too ,and no one is fussing about it，" he said. The traditional way of education applied by most of his peers might not necessarily help bring the best out of a child he said.
Wang said in addition to the physical training, he has also laid out a detailed and particular program to strengthen the intelligence of the child. "I have hired some university students to expand his knowledge in natural sciences, while playing the video for English-language teaching as well," he said.
【小題1】For what reason was Wang made known to the public?

A．He employed some college students to teach his son.
B．He made his kid take a long distance race.
C．He exposed his 4-year-old to cold showers.
D．He forced his youngster to run 3 km every day.
【小題2】Which statement is supported by the parents who hold the opposite opinion?
A．Extreme physical training can explore children's full potentials.
B．Taking cold showers regularly is beneficial for children's development.
C．It's up to parents to lead children on the right path.
D．The way to educate children should agree with their age.
【小題3】What does the phrase "fussing about” probably mean in the 8th paragraph?
A．Minding about. B．Paying attention to.
C．Laughing at. D．Talking about.
【小題4】In Eagle Dad’s opinion, his extreme parenting was questioned because____.
A．he didn’t take it step by step in a scientific way
B．the highly tense work-out was misunderstood
C．modern education is not challenging enough
D．some parents were jealous of his success

Suppose you don't need your car today.And suppose，as it happens that a stranger in your area does need a car.Would you be willing to rent yours out?
Several car­sharing start­ups，including Getaround，RelayRides and JustSharelt，are eager to connect car owners with renters this way.The companies have different rules，but participating owners receive，generally speaking，about two­thirds of the rental earnings.RelayRides says an owner of a mid­size，late­model sedan who rents out a car for 10 hours a week could expect to clear about $ 3,000 a year.
Peer­to­peer car­sharing remains in the trial stage；it can be found in San Francisco and a few other places.It has a long way to go before it becomes the auto equivalent of Airbnb，the  surprise success story for peer­to­peer sharing of space in apartments and houses.
Shelby Clark，founder of RelayRides，says potential investors in his company have been concerned that owners will be afraid to hand their car over to strangers.To address that，he points to Airbnb，saying，“Letting people sleep in your living room is much more of a disturbance into your personal space than letting someone use your car.”
All of these companies offer their own insurance coverage for their renters，which are supposed to put owners' minds at ease.But only two states—California and Oregon—have passed  laws to clarify that an owner will not suffer any consequences should a car­sharing renter have an accident.
“In all the other states，legal ambiguity remains，” Shelby Clark says.“If a renter should be involved in a serious accident in those states，the victim can be expected to go after every party possible，including the car's owner.”
Also to remove the worries of car owners，the driving records of renters are checked for recent serious violations..
【小題1】What does the underlined word “sedan” in Paragraph 2 probably refer to?

A．A kind of car.
B．An owner of a car.
C．A renting company.
D．A car­sharing renter.
【小題2】Which of the following is true of Aribnb?
A．It cares little about personal privacy.
B．It deals with house­sharing successfully.
C．It is a very popular car­sharing company.
D．Its ideas are being tried out in some states.
【小題3】If a car­sharing renter should have an accident in California，the car's owner ________.
A．has to take legal responsibility
B．will not suffer the consequence
C．is not covered by health insurance
D．must pay the insurance for the renter
【小題4】According to the text，more car­owners will participate in the service，if ________.
A．legal ambiguity is clarified in all the states
B．renters are warned not to violate traffic rules
C．more money is given to participating owners
D．people are aware of the importance of sharing
【小題5】It can be learned from the text that car­sharing ________.
A．makes no profit
B．remains in popularity
C．is against the state law
D．is a new business model

Until the 1980s, the American homeless population is mainly made up of older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the U. S. Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient(變化無常的) and frequently frightened student population creates additional problems — both legal and educational — for already overburdened urban school administrators and teachers.
Estimates of the number of homeless Americans range from 350,000 to three million. Likewise, estimates of the number of homeless school children vary radically. A U.S. Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis. But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly.
One part of the homeless population that is particularly difficult to count consists of the “throwaway” youths who have been cast of their homes. The Elementary School Center in New York City estimates that there are 1.5 million of them, many of whom are not treated as children because they do not stay in family shelters and tend to live by themselves on the streets.
Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions（規(guī)定） of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.
【小題1】It is implied in the first paragraph that ____.

A．the writer himself is homeless, even in his eighties
B．many older homeless residents are going on strike in 25 cities
C．there is a serious shortage of academic facilities
D．homeless children are denied the opportunity of receiving free education
【小題2】The National Coalition for the homeless believes that the number of homeless children is _____.
A．350,000B．1,500,000C．440,000D．110,000
【小題3】One part of the homeless population is difficult to estimate. The reason might well be ____.
A．the homeless children are too young to be treated as children
B．the homeless population is growing rapidly
C．the homeless children usually stay outside school
D．some homeless children are deserted by their families
【小題4】The McKinney Act is mentioned in this passage in order to show that ___.
A．the educational problems of homeless children are being recognized
B．the estimates on homeless children are hard to determine
C．the address of grade-school children should be located
D．a(chǎn)ll homeless people should have free education

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict(迷),” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled(皺的).” Today David wears casual clothes — khaki pants and a sports shirt — to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the changes from formal to casual office wear have been slow. In the early 1990s, many companies allowed their workers to wear casual clothes on Friday(but only on Friday). This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for workers has really become an everyday thing,” said business adviser Maisly Jones.?
Why have so many companies started allowing their workers to wear casual clothes? One reason is that it's easier for a company to attract new workers if it has a casual dress code. “A lot of young people don't want to dress up for work,” says the owner of a software company, “so it's hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study made by Levi Strauss and Company, 85 percent of employers said that casual dress has a side effect on work. Supporters of casual office wear also say that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,”one person said. “For the same amount of money, you can buy a lot more casual clothes.”
【小題1】David Smith refers to himself as having been “a clothes addict” because ______________.

A．he often wore khaki pants and a sports shirt 
B．he couldn't stand a clean appearance 
C．he wanted his clothes to look tidy and clean all the time 
D．he didn’t want to spend much money on clothes 
【小題2】David Smith wears casual clothes now, because ______________.
A．they make him feel at ease when working 
B．he cannot afford to buy expensive clothes 
C．he looks handsome in casual clothes 
D．he no longer works for any company 
【小題3】According to this passage, which of the following is TRUE?
A．Company workers started to dress down about twenty years ago. 
B．Dress-down has become an everyday phenomenon since the early 1990s. 
C．“Dress-down Friday” was first given as a favor from employers. 
D．Many workers want to wear casual clothes to impress people. 
【小題4】 In this passage, the following advantages of casual office wear are mentioned EXCEPT  ______________.
A．saving worker’s money B．making workers more attractive 
C．improving worker’s feeling D．making workers happier
