    A dense wave of smog began in the Chinese city of Harbin and the surrounding Heilongjiang, Jilin, and Liaoning Provinces on 20 October 2013. Unseasonably warm temperatures with very little wind across northeastern China coincided with the smoke from local farmers’ burning straws and the start-up of Harbin’s coal-powered central heating system.
    Record densities of fine particulates(微粒)were measured in the city. In Harbin, the levels of PM2.5 (particulate matter) rise to 1,000 micrograms per cubic meter, worse than Beijing’s historic highs. Visibility was reduced to below 50m in parts of Harbin, and below 500m in most of the neighbouring Jilin Province. On Fa Yuen Street in Harbin, visibility of less than 5m was reported. The smog reduced after October 23, 2013 and completely broke up on October 28, 2013 by the first local snow and icy rain due to a cold front moving in from Russia.
    Harbin lies in the north of China where winter temperatures can drop to -40℃, demanding a six-month heating season. Daily particulate levels of more than 40 times the World Health Organization recommended maximum level were reported in parts of Harbin. The smog remained till 23 October, when almost all monitoring stations in Heilongjiang, Jilin,and Liaoning Provincesreported readings above 200μg/m³forPM2.5. PM2.5 is the amount of particulate matter less than 2.5 micrometers in diameter in the air, with the WHO recommending a maximum 24-hour mean (平均值) of 25 micrograms per cubic meter (μg/m³). On the morning of 25 October, PM2.5 measurements in Harbin had fallen to an average of 123μg/m³.
    All highways in the surrounding Heilongjiang Province were closed. In Harbin, all primary and middle schools were closed for three days and authorities stopped flights at the airports. Hospitals reported a 23 percent increase in admissions for breathing problems. However, this smog will have no influence on Harbin Ice Festival events later in December 2013.
    Air pollution in Chinese cities is of increasing concern to China’s leadership. Particulates in the air can affect human health and also have influences on climate and rainfall. Pollution from the burning of coal has reduced life expectancy by 5.5 years in the north of China, as a result of heart and lung diseases.
    小题1:One cause of the heavy smog in the northeastern Chinese cities may be _____.
    A．the lasting cold weather
    B．farmers’ burning of forests
    C．too much strong wind
    D．the start-up of heating system
    小题2:One serious influence of the heavy smog was that_____.
    A．Harbin Ice Festival would be cancelled
    B．highways in Heilongjiang were free of charge
    C．all flights at the airport were cancelled
    D．doctors in hospitals were kept from working
    小题3:The harmful smog was most serious on ______.
    A．October 20B．October 23C．October 25D．October 28
    小题4:What measure might be practical to reduce the happening of heavy smog?
    A．Forbidding people to own their private cars.
    B．Advocating people having one meal a day.
    C．Using natural gas to cook instead of coal.
    D．Encouraging family’s coal-fired heating.

    小题1:D
    小题2:C
    小题3:B
    小题4:C

    Many women write to me perplexed(困惑的) about why they can't form close friendships.They try new approaches，put themselves in all the right places，see therapists，and read relevant self­help books.They consider themselves interesting，loyal，kind，and friend­worthy people.But for reasons unknown to them，they have a tough time forming intimate relationships.Many admit to not having even one close friend.
    A recent study published in the Journal of Personality and Social Psychology offers some clues as to how both nature(personality) and nurture (experience) impact our friendships.Researchers at the University of Virginia and University of Toronto，Mississauga studied more than 7,000 American adults between the ages of 20 and 75 over a period of ten years，looking at the number of times these adults moved during childhood.Their study，like prior ones，showed a link between residential mobility and adult well­being：The more  times participants moved as children，the poorer the quality of their adult social relationships.
    But digging deeper，the researchers found that personality—specifically being introverted (内向的) or extroverted (外向的)—could either intensify or buffer (缓冲) the effect of moving to a new town or neighborhood during childhood.The negative impact of more moves during childhood was far greater for introverts compared to extroverts.
    “Moving a lot makes it difficult for people to maintain long­term close relationships，” stated Dr.Shigehiro Oishi，the first author of the study，in a press release from the American Psychological Association，“This might not be a serious problem for outgoing people who can make friends quickly and easily.Less outgoing people have a harder time making new friends.”
    Families often have to relocate—across town，across the country，or across the globe.Yet，in many cases，their kids and young adolescents haven't yet built up a bank of friendships.So the conventional wisdom is to try to minimize moves for the sake of your child，whenever possible，and to move at the end of the academic year.
    小题1:The passage is written mainly to ________.
    A．offer advice to women on how to form intimate relationships
    B．explain how nature and nurture impact our friendships
    C．explain how moves during childhood affect children
    D．tell us how to help children make friends
    小题2:Which of the following is true according to the second paragraph?
    A．People who moved less during childhood have better social relationships.
    B．The more people moved during childhood，the more friends they have.
    C．The more people moved during childhood，the better they adjust to society.
    D．There is no link between residential mobility and adult well­being.
    小题3:In order for children to maintain long­term close relationships，parents ________.
    A．should not relocate their homes
    B．should relocate their homes within the town
    C．had better move at the end of the school year
    D．had better move when their children couldn't build up a bank of friendships
    小题4:We learn from the fourth paragraph that moves during childhood ________.
    A．have a bigger impact on an introverted person compared to extroverts
    B．have no impact on an outgoing person
    C．are a big problem for both introverts and extroverts
    D．help children better adapt to a new environment
    小题5:We can infer from the passage that ________.
    A．our friendships are mainly affected by our nurture
    B．we can move when children have made a lot of friends
    C．the impact of moves will disappear when one reaches adulthood
    D．there is some way to minimize the impact of moves during childhood on children

    Donna is 19 years old and loves animals, which is why I’m always happy to leave my dog with her when I go on holiday. Donna also helps to train hunting dogs, but recently, her boyfriend told me, she returned home from a farm in tears after being told to hit some dogs.
    “She wasn’t being asked to hit them because they didn’t behave well,” he said. “She was told to punch these puppies with a closed fist simply to let them know who is the boss,” Donna refused. Good for Donna. In my view, you hit an animal for only two reasons: as a way to teach it an important lesson to protect it from danger, such as not into the road; or because you like hurting animals.
    Last summer, I attended a horse race. I don’t know much about horses, but I was alarmed when I saw a horse with a huge ulcer (溃疡) on its legs. “Surely this horse won’t race?” I asked. I was very surprised that nobody in the crowd seemed concerned.
    The horse began the race, but later it fell heavily. It had broken its leg. The next thing I saw was its dead body in a bag, being driven past. No one seemed to care, except those who had bet on it. I know people care for horse racing, but do they really care for horses? I doubt it.
    Oh, but it’s a tradition, I hear you say. Wouldn’t the world be a boring place if we didn’t occasionally hit, shoot and chase animals? Traditions are made by man and can be unmade. It was once acceptable to kill servants when their master died, to visit the mental hospitals to laugh at the patients or to watch public execution (执行死刑).
    Nor should it be forgotten that in our progress to a more civilized world, animals have played an important role: they have fed us, carried us, worked for us, rescued us, died for us and sometimes just saved us from loneliness. Surely by now they deserve our kindness. At the very least, they deserve our respect.
    小题1:Donna was asked to hit the young dogs because ________.
    A．they misbehaved
    B．their owner disliked them
    C．people on the farm enjoy hurting them
    D．it was a way to train them to obey people
    小题2:What does the underlined word in paragraph 2 probably mean?
    A．strikeB．strokeC．scoldD．pump
    小题3:What is the author’s purpose in telling the readers the story about the horse?
    A．To explain the traditional horse race to readers.
    B．To prove that the weak horse can’t win in the race.
    C．To show that animals are treated unfairly by humans.
    D．To say that people care more for horses than horse racing.
    小题4:Which of the following is NOT true?
    A．People no longer watch killing criminals in public.
    B．The author cannot accept anyone who hits the animals.
    C．It was a traditional practice to kill servants for their dead master.
    D．The author thinks it is possible to change the traditions made by man.
    小题5:What’s the best title of the passage?
    A．No One Cares for Animals Nowadays.
    B．Let’s Protect the Endangered Animals.
    C．Show Animals the Respect They Deserve.
    D．The Stories Between Animals and People.

    A quarter of US adults say they read no books at all in the past year, according to an Associated Press-Ipsos survey. The typical person said that he / she read four books in the last year and, excluding those who had not read any books at all, the usual number of books read was seven.
    Of those who did read, women and pensioners (领养老金者) were the most eager readers, and religious works and popular fiction were the top choices. The number of books read was nine books for women and five for men. The number also showed that those with college degrees read the most, and people aged 50 and over read more than those who are younger.
    People from the West and Midwest are more likely to have read at least one book in the past year. Southerners who do read tend to read more books — mostly religious books and romance novels — than people from other regions.
    Those who said they never attend religious services read nearly twice as many books as those who attend frequently, but the Bible and religious works were read by two thirds of the people in the survey, more than all the other categories. Popular fiction, histories, biographies and mysteries took up about half, while one in five read romance novels. Politics, poetry and classical literature were named by fewer than 5% of readers. More women than men read every major category of books except for history and biography books. Men tend to prefer non-fiction.
    Book sales in the US have been flat in recent years and are expected to stay that way, which, experts think, results from competition from the Internet and other media, and the unsteady economy.

    A．the number of Americans who read books last year dropped
    B．the book sales in the US have been dropping in recent years

    Someday a stranger will read your email without your permission or scan the website you have visited. Or perhaps someone will casually glance through your credit card purchases or cell bills to find out your shopping preferences or calling habits.
    In fact, it is likely that some of these things have already happened to you. Who would watch you without permission? It might be a girlfriend, a marketing company, a boss or a criminal. Whoever it is, they will see you in a way you never intended to be seen-----the 21st century is the equal of being caught naked.
    Psychologists tell us boundaries are healthy and that it is important to reveal yourself to friends, families and lovers at appropriate time and places. But now few boundaries remain. The information you leave everywhere makes it easy for strangers to reconstruct who you are, where you are and what you like. Believe it or not, we live in a world where you simply can’t keep a secret. The key question is: does that matter?
    When you ask Americans about privacy, most say they are concerned about losing it.
    But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that can track automobile movements. And few refuse to offer personal information like Social Security numbers to get supermarket loyalty cards.
    But privacy (隐私) does matter—at least sometimes. It is like health: when you have it, you don’t notice it. Only when it is gone do you wish you had done more to protect it.
    小题1:What does the underlined sentence in Para 2 mean?
    A．People’s personal information is easily accessed without their knowing it.
    B．In the 21st century people try every means to look into others’ secrets.
    C．People tend to be more frank with each other in the information age.
    D．Criminals are easily caught on the spot with advanced technology.
    小题2:Which of the statements will the psychologists probably agree with?
    A．Friends should open their hearts to each other.
    B．Friends should always be faithful to each other.
    C．There should be a distance even between friends.
    D．The closer they are, the deeper their friendship is.
    小题3:In the last paragraph but one, the EZ-Pass system and Social Security numbers are used as evidence to show_________.
    A．Americans talk a lot but do little about privacy protection
    B．Americans use various loyalty cards for business.
    C．Americans rely more and more on electronic devices.
    D．Americans change behaviors that might disclose their identity.
    小题4:Which of the following may serve as the best title of the passage?
    A．Privacy and HealthB．Privacy Is Getting Lost.
    C．Boundary and FriendshipD．Cherish What You Have

    When 19­year­old Sophia Giorgi said she was thinking of volunteering to help the Make­A­Wish Foundation(基金会), nobody understood what she was talking about. But Sophia knew just how important Make­A­Wish could be because this special organization had helped to make a dream come true for one of her best friends. We were interested in finding out more, so we went along to meet Sophia and listen to what she had to say.
    Sophia told us that Make­A­Wish is a worldwide organization that started in the United States in 1980. “It's a charity(慈善机构) that helps children who have got very serious illnesses. Make­A­Wish helps children feel happy even though they are sick, by making their wishes and dreams come true，” Sophia explained.

    Sophia also told us the Foundation tries to give children and their families a special, happy time. A Make­A­Wish volunteer visits the families and asks the children what they would wish for if they could have anything in the world. Sophia said the volunteers were important because they were the ones who helped to make the wishes come true. They do this either by providing things that are necessary, or by raising money or helping out in whatever way they can.
    小题1:Sophia found out about Make­A­Wish because her best friend had ________.

    Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person’s shoes．“Shoes convey useful information about their wearers，’’the authors wrote in the new study published in the Journal of Research in Personality．
    Lead researcher Omri Gillath said the judgments were based on the style，cost，color and condition of someone’s shoes．In the study，63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants．Volunteers in the study were photographed in their most commonly worn shoes，and then filled out a personality questionnaire．
    Some of the results were expected：People with higher incomes most commonly wore expensive shoes，and flashier shoes were typically worn by outgoing people．However，some of the more specific results are strange enough．For example，“practical and functional’’ shoes were generally worn by more “pleasant" people，while ankle boots were more linked with ‘‘aggressive’’ personalities．The strangest of all may be that those who wore‘ ‘uncomfortable looking” shoes tend to have “calm” personalities．And if you have several pairs of new shoes or take extreme care of them，you may suffer from “attachment anxiety"，spending lots of time worrying about what other people think of your appearance．There was even a political calculation in the mix with more liberal(主张变革的)types wearing “shabbier and less expensive” shoes．
    The researchers noted that some people will choose shoe styles to mask their actual personalities，but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities．
    小题1:What does this text mainly tell us?
    A．Shoes Call hide people’s real personalities．
    B．Shoes convey false information about the wearer．
    C．People’s personalities call be judged by their shoes．
