You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit（轨道） far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.

    The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet.

    “Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion. 

    The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.

    The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the interior of a comet.

    The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.

    English is an excellent language to learn, whether it's for business, travel or personal reasons. Here are some important ways to improve your spoken English.

    When you have time to speak, just try your best to practice. Don't wait until you “feel more comfortable” speaking in English, so start speaking English today. You'll be surprised at how quickly your language skills improve. Find a native English speaker who is willing to spend some time speaking English with you—you may be able to offer them a language exchange, where they spend 30 minutes speaking English with you and you spend 30 minutes speaking your native language with them.

    Even if you have a good knowledge of the grammar and vocabulary, native English speakers may find it's very difficult to understand if you don't work on your pronunciation. Correct , clear pronunciation is necessary if you really want to improve your English. Listen closely to how native English speakers pronounce certain words and sounds and do your best to copy them.

    The wider your vocabulary and the more English phrases you learn, the easier speaking English will become. Once you have learned a new word or phrase, you should make an effort to use it in a sentence—this is the best way to keep it in mind. You should also start a notebook of phrases that English speakers use all the time.

    Another great way to add some more English conversation into your weekly practice is to sign up for a class of discussion group. Attending an English class is a great way to pay attention to some of the more formal aspects of speaking English. A class will teach you the correct way of speaking. Attending a discussion group is a more informal and relaxed way of learning English, where the emphasis(重点) is more on communication and relationship building than on speaking “correct” English.

    The clock always seems to be ticking rather too fast in the doctor's office and the queue of patients outside the door seems to be pressing rather too hard. Some say it's high time for the model of short, sharp one-to-one appointments to give way to shared medical appointments (SMAs).

    SMAs are doctor-patient visits in which a group of patients receive patient education and counseling (咨询),physical examination and medical support in a group setting. Typically SMAs are designed to have one or more doctors attend to a group of patients who share a common illness or medical condition. In contrast to one-to-one visits, SMAs provide a longer appointment time-frame as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.

    However, doctors who have pioneered the shared appointment approach report that there are significant challenges involved. Dr. Sumego, director of shared medical appointments, Cleveland Clinic, identifies culture change as the most significant challenge. Physicians and nurses are trained in a model of personal service and privacy; the SMA approach is a fundamental challenge to those fixed ideas. They need shared goals and a way of testing the innovation against agreed standards. Dr. Sumego says, "The physicians may be worried about the possible chaos and efficiencies that are marketed. They also have to make the patients understand what their appointment is, and what the expectation is."

    "So, if an organization was looking to start shared medical appointments, I would advise them to start the buy-in from a few champion physicians, develop the work-flow and develop some experience. Provide some support behind what that best practice should look like. Create some standards so that, as the concept spreads, you can employ that experience to start the next shared medical appointments and the next."

    One of the best-loved American writers was William Sydney Porter, or O. Henry. From 1893 he lived with his family in a house in Austin, Texas, which is now a museum. Visitors to Austin can see the house. It was saved from destruction (破坏) and turned into a museum in1934. The museum is a good way to learn about the interesting life of the American writer.

    William Porter rented this house in Austin and lived there with his wife Athol and daughter Margaret for about two years. Many objects in the museum belonged to the Porters. Others did not. An important piece in the room is the original photograph over here. It was taken there in the house about 1895. The piano there goes back to the 1860s. His wife took lessons on it when she first moved to Austin.

    Porter did not start his career as a successful writer. He worked at a farm, land office and bank. He also loved words and writing. The museumm has a special proof of Porter's love of language—his dictionary. It is said that he had read every word in that dictionary.

    Later William Porter was forced to leave Austin because he was charged with financial wrongdoing at the bank and lost his job. Because he was afraid of a trail (审判), he left the country secretly. But he returned because his wife was dying. After her death, he faced the trial and became a criminal. He served three and a half years in a prison in Ohio.

    William Porter would keep his time in prison a secret. But there was one good thing about it. It provided him with time to write. By the time he was freed, he had published 14 stories and became well known as O. Henry.

    Porter later moved to New York City and found great success there. He published over 180 stories in the last eight years of his life.

Being a good parent requires providing a child with the gifts of love, attention, energy, and resources unstintingly over a long period of time. It involves developing a small body, but it also involves growing a child's soul.

Parents are an enormously powerful force in the lives of children. Whether Johnny can read, whether Johnny knows right from wrong, whether Johnny is a happy, well-adjusted kid, or sad and self-destructive, has a whole lot to do with the kind of parenting Johnny has received. If Johnny's mom and dad have been able to come through with lasting, loving attention, the chances are that Johnny is on track to become a productive, compassionate (富有同情心的) person. If they have not, Johnny is in trouble.

Thirty years ago Chicago professor James S. Coleman showed that parental involvement mattered far more in determining school success than any quality of the formal education system. Across a wide range of subject areas, in literature, science and reading, Coleman estimated that the parent was twice as powerful as the school in determining achievement at age fourteen. Psychologist Lawrence Steinberg, who recently completed a six-year study of 20,000 teenagers in nine different communities, confirms the importance of parents. Steinberg shows that one out of three parents is "seriously disengaged" from his or her adolescent's education, and this is the primary reason why so many American students perform below their potential and below students in other rich countries.

A weight of evidence now demonstrates obvious links between absentee parents and a wide range of behavioral and emotional problems in children. A 1997 study of 90,000 teenagers — the Add Health Project undertaken (承担) by the Carolina Population Center and the Teenage Health Program at the University of Minnesota found that youngsters are less likely to get depressed, use drugs or become involved in crime when they spent significant time with their parents. This study found that the mere physical presence of a parent in the home after school, at dinner and at bedtime significantly reduces the incidence of risky behavior among teenagers.
