Imagine you went to a restaurant with a date, had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, "Hey Joe, how are you? Mary is over there in the seat you sat in last time. Would you like to join her for dinner again?" Then you find out that your burger has been cooked and your drink is on the table. Forget the fact that you are with another date and are on a diet that doesn't include burgers. Sound a little odd? To some, it is the same with the Internet. The Nets ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you--some of which you may not want them to have.

    Are you aware that almost every time you access a website you get a "cookie"? Unfortunately, it's not the Mrs.

    Reid's type. A cookie on the Internet is a computer code sent by the site to your computer--usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about your interaction, including where you visit, how long you stay there. How frequently you return to certain pages, and even your electronic address. Fill out a survey to collect free information or samples, and marketers know even more about you--like your name, address, and any other information you provide. While this may sound scary enough, cookies aren't even the latest in technology. A new system called I-librarian Alexa--named for the legendary third century.

    B. C. library in Alexandria, Egypt--does even more. While cookies track what you are doing at one site, Alexa collects data on all your Web activity, such as which sites you visit next, how long you stay there, whether you click on ads, etc. All this information is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don't even know that you are giving it.

    Is any economist so dull as to criticize Christmas? At first glance, the holiday season in western economies seems a treat for those concerned with such vagaries(奇思遐想)as GDP growth. After all, everyone is spending; in America, retailers make 25% of their yearly sales and 60% of their profits between Thanksgiving and Christmas. Even so, economists find something to worry about in the nature of the purchases being made.

    Much of the holiday spending is on gifts for others. At the simplest level, giving gifts involves the giver thinking of something that the recipient would like--he tries to guess her preferences, as economists say--and then buying the gift and delivering it. Yet this guessing of preferences is not easy; indeed, it is often done badly. Every year, ties go unworn and books unread. And even if a gift is enjoyed, it may not be what the recipient would have bought if they had spent the money themselves.

    Interested in this mismatch between wants and gifts, in 1993 Joel Waldfogel, then an economist at Yale University, sought to estimate the difference in dollar terms. In a study, he asked students two questions at the end of a holiday season: first, estimate the total amount paid(by the givers) for all the holiday gifts you received; second, apart from the sentimental value of the items, if you did not have them, how much would you be willing to pay to get them? His results were gloomy: on average, a gift was valued by the recipient well below the price paid by the giver.

    In addition, recipients may not know their own preferences very well. Some of the best gifts, after all, are unexpected items that you would never have thought of buying, but which turn out to be especially well picked. And preferences can change. So by giving a jazz CD, for example, the giver may be encouraging the recipient to enjoy something that was ignored before. This, a desire to build skills, is possibly the hope held by many parents who ignore their children's desires for video games and buy them books instead.

    Finally, there are items that a recipient would like to receive but not purchase. If someone else buys them, however, they can be enjoyed guilt-free. This might explain the volume of chocolate that changes over the holidays. Thus, the lesson for gift-givers is that you should try hard to guess the preference of each person on your list and then choose a gift that will have high sentimental value.

    Here's a list of books I'm looking forward to this fall season. Not all of them will rise to the level of the advertisement, but it's an abundant crop.

    "Home After Dark" by David Small (Liveright, Sept.11)

    In 2009, Small published a celebrated graphic memoir (回忆录) called "Stitches". Now the Caldecott Medal winner is back with a graphic novel about a motherless 13-year-old boy brought up in an unhappy home in California. This is a tale told in few words and many striking images. On Sept. 11 at 3p.m. . Small will be at Amazonbooks at Union Market. More information at www.amazon.com/graph-tale.

    "Waiting for Eden" by Elliot Ackerman (Knopf, Sept. 25)

    This brief novel is related by a dead soldier who is watching over a horribly burned partner in a Texas hospital. That sounds embarrassingly emotional, but Ackerman, who served in a Navy in Iraq and Afghanistan, is one of the best soldier-writers of his generation. More information at www.amazon.com/military-essay.

    "All You Can Ever Know" by Nicole Chung (Catapult, Oct. 2)

    Chung, the editor of the literary magazine Catapult, was adopted as a baby by a white family in Oregon. In this memoir, she writes about her childhood, her Asian American identity and her search for the Korean parents who gave her up. More information at www.amazon.com/politics-prose.

    "Unsheltered" by Barbara Kingsolver (Harper, Oct. 16)

    Alternating between past and present, this novel tells the story of a woman investigating a late-19th-century science teacher who was caught up in the controversy over Darwinism. Like her other novels, this one promises to explore social and scientific problems. Visit www. amazon.com/tech-science for more information.

    Young mums shopping in the Copley Mall in downtown Boston-month found themselves being questioned about their use of soap by students from Harvard Business School usually known as HBS. The students were not doing odd jobs to earn beer money. They were preparing to help a firm in Brazil launch an antibacterial cleanser.

    The 900 students arriving in Boston this summer for their two-year course were told that they would be subjects. The new practical addition to HBS's curriculum is known as "FIELD" that stands for Field Immersion Experiences for Leadership Development. Fieldwork — ie, going out and talking to people — is a big change for HBS.

    Not all the staff and students were overjoyed to be experimented on. But the man responsible, Nitin Nohria, head of HBS, says that "If it works, the FIELD method could become an equal partner to the case method."

    What happens in the second year of the new course is still being worked out. But the first year has three elements. First, team-building exercises. Students take turns to lead a group engaged in a project. They learn to cooperate and to give and take feedback. Second, students will be sent to work for a week with one of more than 140 firms in 11 countries. In the third part of the course, students will be given eight weeks, and seed money of ＄3,000 each, to launch a small company. The most successful, as voted by their fellow students, will get more funding. The experiment does not come cheap, adding 5-10% to the course's cost, which HBS will bear while it figures out what works.

The reasons why people write poems are different and poets use many different forms {#blank#}1{#/blank#} (express) themselves. 

Some of the first poems a young child learns in English are nursery rhymes, {#blank#}2{#/blank#} language has a strong rhythm. The poems are easy {#blank#}3{#/blank#} （learn） and they always make small children {#blank#}4{#/blank#} （delight）. 

One of the {#blank#}5{#/blank#} （simple） kinds of poem is the"list poem"，which has a flexible line length and repeated {#blank#}6{#/blank#}（phrase）which give both a pattern and a rhythm to the poem. 

Another simple form of poem is the cinquain, which {#blank#}7{#/blank#}(make)up of five lines. This kind of poem can convey a strong picture in just a few {#blank#}8{#/blank#}（word）. 

The Japanese haiku consists of 17 syllables and is very popular {#blank#}9{#/blank#}English writers because it is easy to write. 

English speakers like Tang poems from China {#blank#}10{#/blank#}particular and a lot of them have been translated into English.

Finger painting is an art that most people have experienced in childhood. But there are still people who know little about this art form. Finger painting is a simple activity that involves dipping fingers in paints and then using fingers to create objects and shapes on a piece of paper. All you need is a table at elbow height, a few sheets of plain paper, and a few bottles of watercolor. 

When engaging kids in this activity, one should use non-toxic (无毒的) paints only. If not available in the market readily, non-toxic paints can be made at home easily. Preferably, the paints should also be eatable. Finger paints come in bright colors and can be purchased relatively inexpensively. Adults can save money by making their own finger paints using a mixture of cornstarch, food coloring and water.

It is a common fallacy that finger painting is for children alone, rather it's an activity that can be enjoyed by adults in equal measure. Adults can use rubber gloves while painting to avoid dirty marks of paints on their hands. When a group of people are gathered for an exercise of finger painting, it can be a great way of creating a bond between the group. Art and painting parties are a popular concept in the West. Organizations can also use finger painting as a team-building activity by making participants paint together on a large canvas (画布).

There's no limit to the expression of feelings in finger painting. All one needs to do is go all out and put all their feelings on a piece of paper by dipping their fingers in paints. While painting, one may unconsciously choose colors that reflect their emotions. For example, you may choose the color red to express your anger or green to express hope. At times you may be confused, and the painting will help you describe your confused state of mind. Once you get your emotions on paper, you are likely to feel relieved.

So what are you waiting for? Plan a finger-painting session soon, and experience the joy.
