    When it comes to finding their way back home, mice are definitely in the first place. In fact, they find their way around in much the same way we do!

    Recently scientists at Oxford University found that wood mice have a rare ability. They actually create a type of “road sign” to tell themselves which way to go. Until now, most people did not think animals could do this.

    Wood mice live in large open fields. One part of the field looks much like the next. Scientists wondered how wood mice kept from getting lost without landmarks. How did they remember where they hid their food? By studying a group of these mice, researchers learned that these clever mice pile seeds, leaves and other materials at places they want to remember.

    What is truly remarkable is that these markers are visual. Wood mice have large eyes. They rely on their vision to fine their way. House mice, by contrast, follow their own smell to get back to their nests. However, leaving a small trail in an open field could be very dangerous. Enemies might use it to track down the little mice. Wood mice do not have to worry about this. Other animals do not know what their markers mean.

    Researchers wanted to learn more about this unusual behavior. To do so, they needed to study the mice more closely. They decided to place a group of mice inside a box and film their activity. They also put some small plastic discs and a small amount of food in the box. Soon the mice began moving the discs. They used them to hide food. They also shifted them from place to place as they moved farther and farther away from their nesting area.

    Researchers believe this new information may change how people think about these little creatures, and one of the first steps in realizing that mice are not as silly as we probably originally thought. One thing seems certain that these remarkable road signs will be a focus of scientific research for some time to come.

    Facebook means never having to say goodbye. The social media web site has earned a reputation for reconnecting old friends. Last week, a guy whom I hadn't seen since my bachelor party five years ago sent me a friend request. I accepted and waited for him to send me a greeting of some kind. He had sought me out, after all.

    I learned from his profile that he was in a relationship and had a son. However, I'm pretty sure we won’t ever write wall-to-wall, let alone e-mail each other. But he'll remain a friend of online until one of us makes a point of removing the other from his official list.

    My pool of friends consists of family members, college buddies, co-workers from past and present, and friends of friends. There are 35 in all. If I spent some time uploading old e-mail addresses, I'm confident that I could increase my friend count actually.

    A person could make a mission out of reconnecting with childhood friends, former classmates, distant cousins, and those one would like to get to know better. And some people can even handle hundreds of on-screen relationships, keeping up with the daily happenings of their small army of companions. After all, there are worse fates than having too many friends.

    Thanks to e-mail, the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with e-mail, people will lose touch if one or both parties stop writing back. That's normal. People move from school to school, job to job, city to city. You never have to feel guilty for breaking away.

    Every day, the masterminds of Web 2. 0 find new ways of making human communication easier. However, convenience can be a crutch. Some things shouldn't be simplified. When it comes to friendship, there can be no shortcuts.

    According to Paragraph l, the web site is famous because _______.

        A. it has an interesting name of “Facebook”

        B. it helps people get in touch with old friends

        C. it can send people a greeting of some kind

        D. it reminds people of events in the past

    From the second paragraph we can learn that the writer _______.

        A. would write to the friend quite often

        B. asked the friend to e-mail him

        C. did get some information about the friend

        D. would keep in touch with the friend forever

    Which of the following statements is NOT true?

        A. There are 35 people in the author's list of friends right now.

        B. The author communicates with all the 35 friends by e-mails.

        C. The list of 35 friends doesn't include the old e-mail addresses.

        D. It is not difficult for the author to increase his friend count.

    What does the author think of the convenience of communicating on line?

        A. The technology could not keep true friendship forever.

        B. The social web site of Facebook means nothing at all.

        C. There will be no ways of making real friends on line.

      D. People will not lose friends with the help of the Facebook.

    Gallows humor(黑色幽默) may seem like a mistake, or at least in poor taste. But psychologists say that gallows humor can be an important way to relieve stress.“Humor makes you feel in control and it can give you that feeling that everything is okay even when it’s not,”says James M.Jones, a psychology professor at the University of Delaware.

    Psychologists say that just because you’re laughing doesn’t mean you’re wasting time. Occasional tease among colleagues, particularly if it is associated with the job, can inspire creativity, departmental cohesiveness(凝聚力) and performance.

    “There are a lot of stresses out there,”says Ed Dunkelblau, a psychologist in Chicago.“Gallows humor is a way of making difficult things a little less difficult.”

    This is as long as the humor is used for the right purpose. The main point of it should be inspiring people—not laughing at them. “Anything that would lift morale(士气) in terms of the company would be good humor,”says Thierry Guedj, a professor.

    You want to give your employees and co-workers a sense of belonging, so don’t make observations that are aggressive. Most obviously, Dr. Guedj says, don’t make comments about people’s physical appearance or faith. If you have any doubt about its appropriateness, don’t go through with it.

    Or you can take aim at the person that you know won’t be offended(冒犯): yourself. “If there’s going to be a joke or story, it should be you,”Mr Dunkelblau says.

    “People with the ability to laugh at themselves can give other people permission to laugh at themselves, too,”Mr Jones says.“And if you can laugh at yourself, you feel better about yourself.”

    1.According to the passage, gallows humor has the following functions EXCEPT   .

    A．leading to a big mistake

    B．reducing pressure

    C．making people more creative

    D．improving performance

    2.What is Ed Dunkelblau’s attitude towards gallows humor?

    A．Negative.

    B．Positive.

    C．Neutral.(中立的)

    D．Uncertain.

    3.When people use gallows humor, they should      .

    A．observe who is aggressive

    B．show a sense of belonging

    C．doubt about the result of humor

    D．try to avoid involving private things

    4.What can we infer from the passage?

    A．People tend to laugh at others rather than themselves.

    B．Laughing at yourself can make others free from stress.

    C．People can’t avoid offending others with gallows humor.

    D．People who laugh at themselves are easy to gain others’ permission.

     Most people feel lonely sometimes，but it usually only lasts between a few minutes and a few hours，This kind of loneliness is not serious．In fact，it is quite normal．For some people，though，loneliness can last for years．Now researchers say loneliness comes in three different types．

    Eat your vegetables. Wash your hands. Always say “please" and“thank you". We are full of advice for our children, but when it comes to money, we often have little to say. As a result, our children may grow up with clean hands and good manners, but without any idea how to manage their money.

    Here are some basics that will help guide them their entire lives：

    Show them the future. If your 13-year-old girl were to save＄1,000，invest（投资）it at 8%and add＄100 every month，by the time she's 65，she would have＄980,983！

    Be careful of credit（信用）．Credit cards can help you buy necessary things and build a credit history，but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card，you can easily end up paying two or three times what you would have paid if you used cash.

    Teach patience. Suppose your child wants a new bicycle that costs $150. Rather than paying the cash，give him some regular pocket money and explain that by putting aside，say ＄15 each week，he will be able to buy it for himself in only ten weeks.

    Provide incentive. Tell your children the importance of saving.“For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot,”says Cathy Pareto, expert in money planning.

    Explain your values. Values and money are deeply intertwined, says Eilleen Gallo, co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don’t want to buy it.“You might say,‘I'd rather save that money for your education,”，advises Gallo. Every time you spend or don't spend money，you have a chance to share your values.

    64. The underlined word“incentive" in paragraph 6 means _____.

    A. honor          B. praise         C. excitement      D. encouragement

    65. What leads the writer to write this article?

    A. Parents want to know how to educate their children.

    B. He wants to share his good ideas about money matters.

    C. He thinks money management the most important for children.

    D. Parents care little about their children's management of money.

    66. The writer gives some basics to help __________ in a proper way.

    A. parents teach their children how to deal with money 

    B. children follow their parents' instructions

    C. children manage their money                   

    D. parents save their money
