"Oh, you must have been a spoiled(宠坏的) kid. You must be really bossy. I wonder what you're going to be like to deal with?" That's often the response Angela Hult gets when people find out she's an only child, she told ABC News, Despite such negative(消极的) remarks, Hult has decided to have only one child herself. And she's not alone.
According to the US' Office for National Statistics, women approaching the end of their childbearing years had an average of l.9 children in 2004, compared with 3.1 for their counterparts in 1976. The percentage of one-child families in Britain had risen from 18 percent in 1972 to 26 percent in 2007.
But even though only children are becoming increasingly common, the traditional view that they're selfish, spoilt and lack social skills holds strong. Even parents of only children, like Hult, are made to feel guilty about having only one child. Worried that they're being selfish and endangering their child's future, they flock to online discussion forums seeking advice. Soon, however, they ask themselves: is this social prejudice really reasonable?
"There have been hundreds and hundreds of research studies that show that only children are no different from their peers(同龄人) ," Susan Newman, a social psychologist at Rutgers University in the US, told ABC News.
This raises another question: why are only children still viewed with such suspicion?
"There is a belief that's been around probably since humans first existed that to have just one child is somehow dangerous, both for you and for the continuation of your race," Toni Falbo, a professor of educational psychology, told the Guardian." In the past a lot of children died, You'd have had to be crazy to only have one. "
Times, of course, have changed and infant mortality(婴儿死亡率) has largely reduced. So what do only children themselves say?
Kayley Kravitz, a blogger for The Huffington Post, grew up as an only child and highly recommends the experience. "Being an only child taught me the most valuable skill of all: the ability to be alone," she said.
【小题1】Which of the following could be the best title for the text?

A.Are only children lonely?
B.Are only children common?
C.Are only children dangerous?
D.Are only children different?
【小题2】What does Susan Newman mean?
A.Only children are as good as their peers.
B.Only children are more selfish and spoiled.
C.Parents feel guilty about having only one child.
D.Parents will endanger their only child's future.
【小题3】What is the common belief since human existed?
A.The infant death rate always stays high.
B.People are crazy to have only one child.
C.It's easy for only children to earn their living.
D.It's hard to continue the family line with only one child.
【小题4】An only child like Kayley _______.
A.must be difficult to persuade
B.can possibly learn to be alone
C.should value special skills
D.need ignore bad experience
【小题5】What's the author's attitude towards having only one child?
A.Neutral. B.Negative. C.Positive. D.Doubtful.

“ Dining out”, or “ eating out ”,is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before.
However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good ,simple food. As British people don’t dine out every night of the week ,eating in a restaurant is often seen as a special occasion. When going for the first date, or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre.
As in all cultures, there are many rules of etiquette (礼节)surrounding food and eating, and nowhere is this more pronounced than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating.
There’re many such “unspoken” rules — they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain ---the “worst” manners were in Scotland and the northeast, and the “best” in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair.
Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food, from the very cheap to the very expensive — French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry (咖喱菜)rather than any other dish!
As well as dining in a restaurant ,when people are too tired to cook after work they often get a “takeaway”. This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese — and all you have to do is to open the door, pay and eat!
【小题1】 What can be concluded from the first two paragraphs?

A. The British spend more eating out than cooking at home.
B. The British pay great attention to eating in a restaurant.
C. The British often dine out when celebrating festivals.
D. People tend to eat in a restaurant after watching a movie.
【小题2】 The underlined word “pronounced" in Paragraph 3 probably means “_____
A. politeB.expensiveC.strangeD.obvious
【小题3】According to the passage, which of the following statements is true?
A. There exist great differences of rules in different restaurants.
B. People from Wales and southeast Britain are the most polite.
C. Your order in a takeout restaurant can be sent to your home.
D. Traditional British food is seldom served in British restaurants.
【小题4】 What does the passage mainly talk about?
A.Restaurant culture in Britain.
B.Table manners in Britain.
C.Different restaurants in Britain.
D.Traditional and foreign foods in Britain.

For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs. Coupled with the aging of the baby-boom (生育高峰) generation, a longer life span(寿命) means that the nation’s elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change brings many problems for government and society, of course. But it also creates career opportunities in medicine and health professions,  and in law and business as well. “In addition to the doctors, we’re going to need more sociologists, biologists, urban planners and specialized lawyers,” says Professor Edward Schneider of the University of Southern California’s (USC) School of Gerontology (老年学).www.zxxk.com
Lawyers can specialize in “elder law” which covers everything from trusts(信托) and estates to nursing-home abuse and age discrimination. Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees(退休者) in human history. “Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,” one professor says.
Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was “really bored with bacteria.” So she took a class in gerontology and discovered that she liked it. She says, “I did volunteer work in retirement homes and it was very satisfying.”
【小题1】.“…Old is suddenly in” (Line 1, Para. 1) most probably means “_____”.

A.America has suddenly become a nation of old people
B.more elderly professors are found on American campuses
C.gerontology has suddenly become popular
D.American colleges have realized the need of getting older students
【小题2】Why can businessmen make money in the emerging elder market?
A.The elderly possess an enormous purchasing power
B.They can employ more gerontologists
C.Retirees are more generous in spending money
D.There are more elderly people working than before
【小题3】Who can make big money in the new century according to the passage?
A.Retirees who are business-minded
B.The volunteer workers in retirement homes
C.Professionals with a good knowledge of gerontology
D.College graduates with an MBA or law degree
【小题4】.It can be seen from the passage that the expansion of America’s elderly population ______.
A.will provide good job opportunities in many areas
B.will cause a heavy burden on society
C.may lead to nursing home abuse and age discrimination
D.will create new fields of study in universities

If Confucius(孔子)were still alive today and could celebrate his September 28 birthday with a big cake, there would be many candles. He’d need a fan or a strong wind to help him put them out.
While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It’s nothing personal. Most Americans don’t even remember the birthdays of their own national heroes.
But this doesn’t mean that Americans don’t care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.
In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and philosophy(哲学). Some social scientists suggest that Westerners should take advantages of the ancient Chinese wisdom to make up for the drawbacks of Westerners philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States.  Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers. 
So the old thinker’s ideas are still alive and well.
Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.
As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.
【小题1】The opening paragraph is mainly intended to ________

A.provide some key facts about Confucius
B.attract the readers’ interest in the subject
C.show great respect for the ancient thinker
D.prove the popularity of modern birthday celebrations
【小题2】 We can learn from Paragraph 4 that American students______
A.have a great interest in studying Chinese
B.take an active part in Chinese competitions
C.try to get high scores in Chinese exams
D.fight for a chance to learn Chinese
【小题3】What is the best title for the passage?
A.Forgotten Wisdom in America
B.Huge Fans of the Chinese Language
C.Chinese Culture for Westerners
D.Old Thinker with a Big Future
【小题4】The passage is likely to appear in ___________.
A.a biography(自传)B.a history paperC.a newspaperD.a philosophy textbook

A new study suggests that the round­the­clock availability that cell phones have brought to people's lives may take a toll on family life. The study,which followed more than 1,300 adults over 2 years, found that those who consistently used a mobile phone throughout the study period were more likely to report negative “spillover” between work and home life—and,in turn,less satisfaction with their family life.
Spillover essentially(本质上)means that the line between work and home begins to become unclear. Work life may invade home life when a parent is taking job­related calls at home,for instance—or family issues may start to take up work time. For example,a child may call mum at work,telling her “microwave exploded”,explained Noelle Chesley,an assistant professor of sociology at the University of Wisconsin­Milwaukee and the author of the study. The problem with cell phones seems to be that they are allowing for even more spillover between work and home.
This may be especially true for working women,the study found. Among men,consistent use of mobile phones seemed to allow more work issues to creep (潜入)into family time. But for women,the spillover tended to go in both directions. Being “connected” meant that work cut into home time,and family issues came into work life.
Cell phones seem to be opening more lines for stressful exchanges among family members. But there may be ways to control the spillover,according to Chesley. Employers, she said,could look at their policies on contacting employees after hours to make sure their expectations are “reasonable”.For their part,employees could decide that cell phones go off during family time, Chesley said.
【小题1】What does the underlined phrase “take a toll on” probably mean in Paragraph 1?

A.explaining. B.founding.C.extendingD.damaging.
【小题2】According to Chesley,what is the best solution to the problem caused by cell phones?
A.Separate work hours from family time.
B.Refuse to use cell phones.
C.Ignore coming calls during family time.
D.Encourage women to stay at home.
【小题3】We can learn from the passage that ________.
A.cell phones affect men as much as women
B.cell phones seem to be convenient to families
C.cell phones make the line between work and home unclear
D.we can do nothing to solve the problem
【小题4】What is the main idea of the passage?
A. How to control the negative spillover caused by cell phones.
B.How work life invades home life.
C.Consistent use of cell phones makes people feel less satisfied with their work.
D. Cell phones cause negative "spillover" between work life and home life.

Aggressive pedestrians are in fact as dangerous as careless drivers. They cause traffic accidents, injury and death. These dangerous walkers can be seen in any big city all over the world. About 69% of last year’s pedestrian deaths in the US occurred in urban areas. They cross streets ignoring “DON’T WALK” signals, suddenly appear without warning from behind parked vehicles, walk slowly at crossroads with cell phones attached to heads, blocking traffic.
These pedestrians and drivers share a common disregard for the rules of the road, both for selfish reasons. The drivers believe in the power of their machines. If their machines can go faster, they believe they have the right to go faster. If their machines are bigger, they believe they have the right to push smaller vehicles aside. Aggressive pedestrians, on the other hand, believe in the primacy(首位) of the individual, the idea that they are first in any environment, under any circumstances, even when they are on foot in a roaring tide of steel and rubber.
Last year, an estimated 5,220 pedestrians died in traffic accidents. Some 69,000 pedestrians were injured. On average, that worked out to one pedestrian killed in a traffic crash every 101 minutes, and one injured every eight minutes.
The good news is that the accident rate is dropping. For example, the number of pedestrians killed last year was 24 percent less than the number killed in traffic accidents a decade earlier. The bad news is that the basic causes of pedestrian deaths remain pretty much the same----disregard for traffic signals, inattention and crossing roads under the influence of alcohol and drugs. Alcohol, in fact, was involved in 46 percent of the traffic accidents that resulted in pedestrian deaths. Of those, 31 percent of the pedestrians were found to be drunk.
The bottom line is that the pedestrians must do more to protect their lives as well as the lives of other road users. They can start by obeying traffic signals, using marked cross-walks and calling a cab when they’ve had too much to drink.
【小题1】The passage is mainly about _____.

A.what the traffic rules of the road about pedestrians were
B.why so many Americans were killed on roads last year
C.how aggressive pedestrians cause traffic accidents
D.who are to blame for pedestrian deaths, drunk drivers or the aggressive pedestrians
【小题2】What is the pedestrians’ selfish reason for traffic jams?
A.They believe individuals are always first.
B.They know all drivers are skilled and with great care.
C.They think traffic rules have nothing to do with them.
D.They guess all vehicles will slow down at crossroads.
【小题3】What was NOT the basic cause of pedestrian deaths in the US a decade ago?
A.Disregard for traffic signals
B.Paying no attention to surroundings.
C.Overspeeding driving.
D.Crossing roads drunk.
【小题4】What word can best describe the author’s attitude to the traffic accidents caused by pedestrians?
A.Excited.B.Cold.C.Unconnected. D.Concerned

It is often said that you cannot “teach an old dog new tricks”, but three New Zealand dogs have decided to prove otherwise by learning a skill --- driving a car!
What's even more impressive is that the three who have become skilled in just eight weeks are not special dogs that belong to some rich owners, but abandoned ones at New Zealand's SPCA.
To get their training started, 10-month old Porter, 18-month-old Monty and one-year-old Ginny were selected from a pool of seven potential candidates and moved to Animal Q, a talent agency that teaches animals tricks for movies and television shows.
The driving classes began with teaching the dogs some basic driving techniques like turning the steering wheels(方向盘)and applying the brakes. After that the dogs practiced everything they had learnt behind the wheels of a motorized(装上发动机的)car. Then finally, it was time for the big test--- driving a real car!
Human cars are not really built for four-legged animals, so the car they drove was adjusted so that the dogs could sit comfortably and easily reach the steering wheel with their paws.
Though they all seemed to do very well, the real test came on Monday night when Monty, the best driver of the three, showed his great driving skill on live television.
Why would the SPCA go through so much trouble to highlight the skills of homeless dogs?  The reason is to show that adopting a dog from a shelter does not mean owners are getting a pet that is worse than one purchased from a keeper. The CEO of the SPCA is hoping that this unusual event will be enough to convince the residents of New Zealand to consider them, when searching for a pet.
We surely hope so, meanwhile we are almost certain that these three pioneers have at least landed their names in the Guinness World Records, creating a category that probably does not even exist today!
【小题1】Who do the three dogs belong to?

A.Some rich owners. B.Animal Q. C.A shelter. D.A zoo.
【小题2】The car the dogs drove was adjusted ______.
A.because is was too big for the dogs to drive
B.because it had no steering wheels and brakes
C.to ensure the dogs could sit comfortably and drive easily
D.to motorize the car and turn it to be a real one
【小题3】Which is the right order of the following events?
a. Teaching the dogs some basic driving techniques.
b. Selecting three dogs and moving them to Animal Q.
c. The dogs practiced everything they had learnt in a motorized car.
d. Choosing the best driver to show his great driving skill on live television.
e. Driving a real car.
A.a-b-c- d-e B.b-a-c-e-d C. b- d- a-c-e D.a- e- c-b-d
【小题4】Why does the SPCA decide to teach the three dogs to learn to drive a car?
A.To prove old dogs can learn new tricks.
B.To teach them performing tricks for movies and television shows.
C.To provide amusing performances for homeless children
D.To encourage people to adopt the abandoned dogs.
【小题5】What can we learn from the passage?
A.A new Guinness category for driving dogs will probably be created.
B.Abandoned dogs are much cleverer than house-kept ones.
C.All the dogs at New Zealand’s SPCA will soon be adopted.
D.New Zealand has the most homeless dogs among all countries

Ceaseless technology. A punishing workweek. That to –do list that keeps multiplying. It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing (小睡)? One sleep expert, W. Christopher Winter raised the question.
Sleeping binge
Getting eight hours of shut-eye each night is generally recommended, but many people don’t. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them “ catch up” on lost sleep. They’re likely right, “ Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work,” says Dr. Winter, a member of the American Academy of Sleep Medicine.
Sleep banking
Recent data suggests that banking sleep in advance of a long night can actually offset (补偿) upcoming sleep deprivation(丧失). If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead.
Routine (惯例的)naps
A scheduled nap is healthier than catching up on or banking sleep. “ Because sleep extension can make you feel groggy (昏昏沉沉), I always recommend a short nap [if a person feels they need it ], at the same time, every day,” says Dr. Winter. He adds that 25 minutes is ideal. “ When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep,” he says. That refreshing, scheduled break is better than an occasional weekend lie-in. “ The body likes routine,” he says, “ When it’s prepared, it works more efficiently.”
【小题1】From Monday to Friday, many people _________.

A.accumulate a sleep debtB.have no time to sleep
C.work hard to achieve their goalsD.have to stay up all nights
【小题2】Research shows that in the short term________.
A.a nap have no effect on work
B.a nap have effect on work
C.recovery sleep does work
D.recovery sleep doesn’t work
【小题3】If a soccer fan wants to stay up all night to watch two World Cup semi-finals, it may help if ________.
A.he keeps taking a nap for a week
B.he sleeps for 8 hours a day for days
C.he keeps sleeping for 2 days
D.he banks sleep in advance
【小题4】What is better than banking sleep, according to Dr. Winter?
A.Sleeping bingeB.Recovery sleep
C.Scheduled napsD.Sleep extension
【小题5】What would be the best title for the passage?
A.Sleep MattersB.Disadvantage of Sleeping Binge
C.Advantage of Routine NapsD.How to Sleep Well
