The Great Wall of China is considered to be the only man－made project seen from the moon. Although it was once thought to have been built entirely during the Qin Dynasty( 朝代) between 221 and 208 BC, it is now believed to have been started earlier.The 15－foot－high, 25－foot－wide, 1,500－mile－long structure was undoubtedly built to keep out invading enemies. To the common people of the empire, who had been forced to build the wall, it was not worth it, however. The wall, and other public works completed by the Qin Dynasty, had caused great losses on the wealth and human life of the country.

When you watch television, you hear and see an advertisement. If you turn the pages of a newspaper or magazine, again you find an advertisement. If you walk down the street, you see one advertising board after another. All day, every day, people who want to sell you something compete to catch your attention.In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned. The government does not give them money. So where does the money come from? From advertisements. Without advertisements, there would notHave you ever asked yourself what advertising is? Through the years, people have given different answers to the question. For some time it was felt that advertising was a means of “keeping your name before the public.” And some people thought that advertising was “truth well told.” Now more and more people describe it in this way: Advertising is the paid, nonpersonal (非针对某个人的), and usually persuasive (有说服力的) description of goods, services and ideas by identified sponsors (明确的出资者)through various media.First, advertising is usually paid for. Various sponsors pay for the advert sements we see, read, and hear over the various media. Second, advertising is nonpersonal. It is not face to face communication. Although you may feel that a message in a certain advertisement is aimed directly at you, in reality, it is directed at large groups of people. Third, advertising is usually persuasive. Directly or indirectly it tells people to do something. All advertisements try to make people believe that the product, idea, or service advertised can do good to them. Fourth, the sponsor of the advertisement must be identified. From the advertisement, we can see if the sponsor is a company, or an organization, or an individual. Fifth, advertising reaches us through traditional (传统的)and nontraditional mass media. Included in the traditional media arenewspapers, magazines, radio, television, and films. Nontraditional media include the mail, matchbox covers, and billboards (广告牌62.

Computers hackers (黑客) have broken down security（安全）systems, raising questions about the safety of cardholder information. Several months ago, 25,000 customers of CD Universe, an on－line music retailer (零售商) , were not lucky. Their names, addresses and credit－card numbers were posted on a Web site after the retailer refused to pay US $157,828 to getCredit－card firms are now fighting against on－line fraud. Mastercard is working on plans for Web－only credit card, with a lower credit limit. The card could be used only for shopping on－line.

E－mail the site your credit－Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only have to share your children's curiosity(好奇). Firstly, listen to their questions.I once visited a classroom of seven－year－olds to talk about science asa job. The children asked me “textbook questions” about schooling, salary（薪水） and whether I liked my job. When I finished answering, we sat facing one another in silence. Fina lly I said, “Now that we're finished with your lists, do you have questions of your own aboutAfter a long pause, a boy raised his hand, “Have you ever seen a grasshopper (蚱蜢) eat? When I try eating leaves like that, I get astomachache. Why?”Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and creative answers.Thirdly, watch your language. Once you have a child involved in a science discussion, don't jump in with “That's right” or “Very good”. These words work well when it comes to encouraging good behavior(行为). But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, “That's interesting” or “I'd never thought of it that way before”, or coming up with moreNever push a child to “Think”. It doesn't make sense, children are always thinking, without your telling them to. What's more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target (目标Lastly, show; don't tell. Real－life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发), set a pot of water to boil and let them watch the water level drop.71.
