Advertisements come into our lives in a variety of forms. Newspapers carry advertisements. Billboards carry advertisements. More conspicuously, TV advertisements are incessantly influencing people’s life from various aspects.
Advertisements have many advantages. Firstly, advertising is informative, which provides us with a quick access to the product needed. Secondly, many advertisements, especially TV advertisemnts are so beautifully made that they themselves can bring us great enjoyment. Maybe that’s why the daughter in the picture is so attracted by them.
However, advertising involves some defects. Firstly, the cost of adverting will definitely be passed on to the customers, which makes the products be sold at much higher prices. Thirdly, Secondly, The advertisers often mispresent the truth by exaggerating the benefits of the merchandise they want to sell. Thirdly, advertisements often interrupt audiences’ appreciation of their favorite programs, which may lead to diasspointment and frustration, the expression written on the face of the father in the picuture,
As far as I am concerned, I tend to be in favor of the positive effects. Undoubtedly, nothing is more important than convenience for people living in a so quick-paced society. I believe that the negative effects can be minimized through sustainable economic growth and education.

Vinton Cerf, known as the father of the Internet, said on Wednesday that the Web was outgrowing the planet Earth and the time had come to take the information superhighway to outer space.
“The Internet is growing quickly, and we still have a lot of work to do to cover the planet.” Cerf told the first day of the annual conference of Internet Society in Geneva where more than 1500 cyberspace fans have gathered to seek answers to questions about the tangled web of the Internet.
Cerf believed that it would soon be possible to send real-time science data on the Internet from a space mission orbiting another planet such as Mars. “There is now an effort under way to design and build an interplanetary Internet. The space research community is coming closer and closer and merging. We think that we will see interplanetary Internet networks that look very much like the ones we use today. We will need interplanetary gateways and there will be protocols to transmit data between these gateways, ” Cerf said.
Francois Fluckiger, a scientist attending the conference from the European Particle Physics Laboratory near Geneva, was not entirely convinced, saying: “We need dreams like this. But I don’t know any Martian whom I’d like to communicate with through the Internet.”
Cerf has been working with NASA’s Pasadena Jet Propulsion Laboratory—the people behind the recent Mars expedition—to design what he calls an “interplanetary Internet protocol.” He believes that astronauts will want to use the Internet, although special problems remain with interference and delay.
“This is quite real. The effort is becoming extraordinarily concrete over the next few months because the next Mars mission is in planning stages now,” Cerf told the conference.
“If we use domain names like Earth or Mars…jet propulsion laboratory people would be coming together with people from the Internet community.” He added.
“The idea is to take the interplanetary Internet design and make it a part of the infrastructure of the Mars mission.”
He later told a news conference that designing this system now would prepare mankind for future technological advances.
“The whole idea is to create an architecture so the design works anywhere. I don’t know where we’re going to have to put it but my guess is that we’ll be going out there some time,” Cerf said.
“If you think 100 years from now, it is entirely possible that what will be purely research 50 years from now will become commercial 100 years from now. The Internet was the same—it started as pure research but now it is commercialized.”

The popularization of computer has made it possible to read books on computer. With it, there is much discussion about whether e-books will replace traditional print-on-paper books.
Some people say they like only e-books, which are quicker and more convenient to get and use. To get a needed book, one has to spend much time or money in searching for or buying it in bookstores, but one can just type in the title, author or other related information of the book to find it in minutes on internet. Sometimes one can even read the full content of a digitized book free of charge or instantly discuss about a book in an online forum. Moreover, a lot of information of books can be stored in a small compact disc, which is easy to take.
Other people, however, think printed books are still necessary. In the first place, too much time in front of the computer can cause eyestrain or increase radiation risks. Second, a printed book can be read at your convenience. One can read in bed before sleep or during a boring journey, without fussing with a computer.
In sum, since e-books and printed books have their respective advantages and can complement each other, I would like to combine the two ways to meet different needs. For quick reference, a digitized book will probably be useful. To appreciate a poem or a novel, I prefer the traditional way of reading on printed books.

There have been rumors. There’s been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Fox’s hit TV show Ally McBeal, is so thin. And we in the media are falling all over ourselves trying to figure out whether Flockhart has an eating disorder, especially now that she has denied it. Well, I’m not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldn’t need so many slender celebrities in the first place.
But the fact remains that 2 million Americans—most of them women and girls—do suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at greater risk of developing brittle bones, life-threatening infections, kidney damage and heart problems. Fortunately, doctors have learned a lot over the past decade about what causes eating disorders and how to treat them.
The numbers are shocking. Approximately 1 in 150 teenage girls in the U. S. falls victim to anorexia nervosa, broadly defined as the refusal to eat enough to maintain even a minimal body weight. Not so clear is how many more suffer from bulimia, in which they binge on food, eating perhaps two or three days’ worth of meals in 30 minutes, then remove the excess by taking medicine to move the bowels or inducing vomiting. Nor does age necessarily protect you. Anorexia has been diagnosed in girls as young as eight. Most deaths from the condition occur in women over 45.
Doctors used to think eating disorders were purely psychological. Now they realize there’s some problematic biology as well. In a study published in the Archives of General Psychiatry recently, researchers found abnormal levels of serotonin, a neurotransmitter in the brain, in women who had been free of bulimia for at least a year. That may help explain why drugs have allowed a lot of people to stop swallowing in large doses of food. Unfortunately, the pills don’t work as well for denial of food. Nor do they offer a simple one-stop cure. Health-care workers must re-educate their patients in how to eat and think about food.
How can you tell if someone you love has an eating disorder? “Bulimics will often leave evidence around as if they want to get caught.” Says Tamara Pryor, director of an eating-disorders clinic at the University of Kansas in Wichita. Anorexics, by contrast, are more likely to go through long periods of denial.

U. S.-led occupation authorities have begun a secret campaign to recruit and train agents with the once-dreaded Iraqi intelligence service to help identify resistance to American forces here after months of increasingly sophisticated attacks and bombings, according to U.S.. and Iraqi officials.
The extraordinary move to recruit agents of former president’s security services demonstrates a growing recognition among U.S. officials that American military forces—already stretched thin—cannot alone prevent attacks like the devastating truck bombing of the U.N. headquarters recently, the officials said.
Authorities have stepped up the recruitment over the past two weeks, one senior U.S. official said, despite sometimes firm objections by members of the U.S.-appointed Iraqi Governing Council, who complain that they have too little control over the pool of recruits. While U.S. officials acknowledge the sensitivity of cooperating with a force that embodied the ruthlessness of the overthrown president’s rule, they assert that an urgent need for better and more precise intelligence has forced unusual compromises.
“The only way you can combat terrorism is through intelligence,” the senior official said. “It’s the only way you’re going to stop these people from doing what they’re doing.” He added: “Without Iraqi input, that’s not going to work.”
Officials are reluctant to disclose how many former agents have been recruited since the effort began. But Iraqi officials say they number anywhere from dozens to a few hundred, and U.S. officials acknowledge that the recruitment is extensive.
“We’re reaching out very widely,” said one official with the U.S.-led administration, who like most spoke on condition of anonymity because of sensitivity over questions of intelligence and sources.
Added a Western diplomat: “There is an obvious evolution in American thinking. First the police are reconstituted, then the army. It is logical that intelligence officials from the regime would also be recruited.”
Officials say the first line of intelligence-gathering remains the Iraqi police, who number 6,500 in Baghdad and 33,000 nationwide. But that force is hampered in intelligence work by a lack of credibility with a belief-broken public, and its numbers remain far below what U.S. officials say they need to bring order to an unruly capital. Across Iraq, walk-in informers have provided tips on weapons hidings and locations of suspected guerrillas, but many Iraqis dismiss those reports as occasional and sometimes motivated by a desire for personal gain.
The emphasis in recruitment appears to be on the intelligence service known as the Mukhabarat, one of four branches in the former security service, although it is not the only target for the U.S. effort. The Mukhabarat, whose name itself inspired fear in ordinary Iraqis, was the foreign intelligence service, the most sophisticated of the four.

One of the most important social developments that helped to make possible a shift in thinking about the role of public education was the effect of the baby boom of the 1950’s and 1960’s on the schools. In the 1920’s, but especially in the Depression conditions of the 1930’s, the United States experienced a declining birth rate — every thousand women aged fifteen to forty-four gave birth to about 118 live children in 1920, 89.2 in 1930, 75.8 in 1936, and 80 in 1940. With the growing prosperity brought on by the Second World War and the economic boom that followed it young people married and established households earlier and began to raise larger families than had their predecessors during the Depression. Birth rates rose to 102 per thousand in 1946,106.2 in 1950, and 118 in 1955. Although economics was probably the most important determinant, it is not the only explanation for the baby boom. The increased value placed on the idea of the family also helps to explain this rise in birth rates. The baby boomers began streaming into the first grade by the mid 1940’s and became a flood by 1950. The public school system suddenly found itself overtaxed. While the number of schoolchildren rose because of wartime and postwar conditions, these same conditions made the schools even less prepared to cope with the food. The wartime economy meant that few new schools were built between 1940 and 1945. Moreover, during the war and in the boom times that followed, large numbers of teachers left their profession for better-paying jobs elsewhere in the economy.
Therefore in the 1950’s and 1960’s, the baby boom hit an antiquated and inadequate school system. Consequently, the “ custodial rhetoric” of the 1930’s and early 1940’s no longer made sense that is, keeping youths aged sixteen and older out of the labor market by keeping them in school could no longer be a high priority for an institution unable to find space and staff to teach younger children aged five to sixteen. With the baby boom, the focus of educators and of laymen interested in education inevitably turned toward the lower grades and back to basic academic skills and discipline. The system no longer had much interest in offering nontraditional, new, and extra services to older youths.

Over the last decade, demand for the most common cosmetic surgery procedures, like breast enlargements and nose jobs, has increased by more than 400 percent. According to Dr. Dai Davies, of the Plastic Surgery Partnership in Hammersmith, the majority of cosmetic surgery patients are not chasing physical perfection. Rather, they are driven to fantastic lengths to improve their appearance by a desire to look normal. “What we all crave is to look normal, and normal is what is prescribed by the advertising media and other external pressures. They give us a perception of what is physically acceptable and we feel we must look like that.”
In America, the debate is no longer about whether surgery is normal; rather, it centres on what age people should be before going under the knife. New York surgeon Dr. Gerard Imber recommends “maintenance” work for people in their thirties. “The idea of waiting until one needs a heroic transformation is silly,” he says. “By then, you’ve wasted 20 great years of your life and allowed things to get out of hand.” Dr. Imber draws the line at operating on people who are under 18, however. “It seems that someone we don’t consider old enough to order a drink shouldn’t be considering plastic surgery.”
In the UK cosmetic surgery has long been seen as the exclusive domain of the very rich and famous. But the proportionate cost of treatment has fallen substantially, bringing all but the most advanced laser technology within the reach of most people. Dr. Davies, who claims to “cater for the average person”, agrees. He says:“I treat a few of the rich and famous and an awful lot of secretaries. Of course, ￡3,000 for an operation is a lot of money. But it is also an investment for life which costs about half the price of a good family holiday.”
Dr. Davies suspects that the increasing sophistication of the fat injecting and removal techniques that allow patients to be treated with a local anaesthetic in an afternoon has also helped promote the popularity of cosmetic surgery. Yet, as one woman who recently paid ￡2,500 for liposuction to remove fat from her thighs admitted, the slope to becoming a cosmetic surgery Veteran is a deceptively gentle one. “I had my legs done because they’d been bugging me for years. But going into the clinic was so low key and effective it whetted my appetite. Now I don’t think there’s any operation that I would rule out having if I could afford it.”

The author of some forty novels, a number of plays, volumes of verse, historical, critical and autobiographical works, an editor and translator, Jack Lindsay is clearly an extraordinarily prolific writer—a fact which can easily obscure his very real distinction in some of the areas into which he has ventured. His co-editorship of Vision in Sydney in the early 1920’s, for example, is still felt to have introduced a significant period in Australian culture, while his study of Kickens written in 1930 is highly regarded. But of all his work it is probably the novel to which he has made his most significant contribution.
Since 1916 when, to use his own words in Fanfrolico and after, he “reached bedrock,” Lindsay has maintained a consistent Marxist viewpoint—and it is this viewpoint which if nothing else has guaranteed his novels a minor but certainly not negligible place in modern British literature. Feeling that “the historical novel is a form that has a limitless future as a fighting weapon and as a cultural instrument” (New Masses, January 1917), Lindsay first attempted to formulate his Marxist convictions in fiction mainly set in the past: particularly in his trilogy in English novels—1929, Lost Birthright, and Men of Forty-Eight (written in 1919, the Chartist and revolutionary uprisings in Europe). Basically these works set out, with most success in the first volume, to vivify the historical traditions behind English Socialism and attempted to demonstrate that it stood, in Lindsay’s words, for the “true completion of the national destiny.”
Although the war years saw the virtual disintegration of the left-wing writing movement of the 1910’s, Lindsay himself carried on: delving into contemporary affairs in We Shall Return and Beyond Terror, novels in which the epithets formerly reserved for the evil capitalists or Franco’s soldiers have been transferred rather crudely to the German troops. After the war Lindsay continued to write mainly about the present—trying with varying degrees of success to come to terms with the unradical political realities of post-war England. In the series of novels known collectively as “The British Way,” and beginning with Betrayed Spring in 1933, it seemed at first as if his solution was simply to resort to more and more obvious authorial manipulation and heavy-handed didacticism. Fortunately, however, from Revolt of the Sons, this process was reversed, as Lindsay began to show an increasing tendency to ignore party solutions, to fail indeed to give anything but the most elementary political consciousness to his characters, so that in his latest (and what appears to be his last) contemporary novel, Choice of Times, his hero, Colin, ends on a note of desperation: “Everything must be different, I can’t live this way any longer. But how can I change it, how?” To his credit as an artist, Lindsay doesn’t give him any explicit answer.

Between 5,000 million and 4,000 million years ago the Earth was formed. By 3,000 million years ago life had arisen and we have fossils of microscopic bacteria like creatures to prove it. Some time between these two dates—independent molecular evidence suggests about 4,000 million years ago—that mysterious event, the origin of life, must have occurred.. Nobody knows what happened, but theorists agree that the key was the spontaneous arising of self replicating entities, i.e. something equivalent to “genes” in the general sense.
The atmosphere of the early Earth probably contained gases still abundant today on other planets in the solar system. Chemists have experimentally reconstructed these ancientconditions in the laboratory. If plausible gases are mixed in a flask with water, and energy is added by an electric discharge (simulated lightning), organic substances are spontaneously synthesized. These include the building blocks of RNA and DNA. It seems probable that something like this happened on the early Earth. Consequently, the sea would have become a “soup” of prebiological organic compounds. It is not enough, of course, that organic molecules appeared in the primeval soup. The crucial step, as noted above, was the origin of selfreplicating molecules, molecules capable of copying themselves.
Today the most famous selfreplicating molecule is DNA (deoxyribonucleic acid), but it is widely thought that DNA itself could not have been present at the origin of life because its replication is too dependent on support from specialized machinery, which could not have been available before evolution itself began. DNA has been described as a “hightech” molecule which probably arose some time after the origin of life itself. Perhaps the related molecule RNA, which still plays various vital roles in living cells, was the original selfreplicating molecule. Or perhaps the primordial replicator was a different kind of molecule altogether. Once selfreplicating molecules had been formed by chance, something like Darwinian natural selection could have begun: variation would have come into the population because of random errors in copying. Variants that were particularly good at replication would automatically have come to predominate in the primeval soup. Varieties that did not replicate, or that did so inaccurately, would have become relatively less numerous. This led to everincreasing efficiency among replicating molecules.
As the competition between replicating molecules warmed up, success must have gone to the ones that happened to hit upon special tricks or devices for their own selfpreservation and their own rapid replication. The rest of evolution may be regarded as a continuation of the natural selection of replicator molecules, now called genes, by virtue of their capacity to build for themselves efficient devices (cells and multicellular bodies) for their own preservation and reproduction. Three thousand million years is a long time, and it seems to have been long enough to have produced such astonishingly complex contrivances as the vertebrate body and the insect body.
Fossils were not laid down on more than a small scale until the Cambrian era, nearly 600 million years ago. The first vertebrates may date back 530 million years, according to fossil evidence—primitive, jawless fishes with fins, gills, and fishlike muscle patterns—found in China in 1999. Vertebrates appear abundantly in fossil beds between 300 and 400 million years ago. Among vertebrates, the land was first colonized by lobefinned and lungbearing fish about 250 million years ago, then by amphibians and, in more thoroughgoing fashion, by various kinds of animals that we loosely lump together as “reptiles”. Mammals and, later, birds, arose from two different branches of reptiles. The rapid divergence of mammals into the rich variety of types that we see today, from opossums to elephants, from anteaters to monkeys, seems to have been unleashed into the vacuum left by the catastrophic extinction of the dinosaurs, 65 million years ago.

You slip the key into the ignition and crank the engine to life. But before you put the car into gear, you tap a key on the keyboard mounted by the steering wheel, and your newest email flashes up on the windscreen.
This seductive satyr is what you get when you cross a car and a computer. Dubbed the “network vehicle”, or net-mobile, it may soon come to a driveway near you (probably the one belonging to your rich neighbour). In a net-mobile, a motorist could tap into a regional road system but also to map out a route around rush-hour traffic snags. Drivers and passengers will be able to send and receive e-mail, track the latest sports scores or stock quotes, surf the Web, and even play video games. Or so, at least, say a number of computer-industry firms such as Microsoft, Sun, IBM and Netscape.
The modern car is already an electronic showcase on wheels. On-board microcomputers improve fuel economy and reduce emissions. They operate anti-lock brake systems, and on some cars even regulate the firmness of the shock absorbers. But much of the technology needed to add extra is available now. A prototype network vehicle, produced by a consortium of Netscape, Sun, IBM and Delco (an automotive electronics firm based in Michigan), was introduced at the recent annual computerindustry show in Las Vegas.
It not only offered such desktop-computer-like services as e-mail, but allowed a driver to use them without looking away from the road. It was operated by voice commands and projected its data on to the windscreen, using the same sort of head-up display system found in modern fighter jets. Members of the consortium think a real-world network vehicle could be in production in as little as four years.
Car-makers have already begun rolling out some of the features found on these prototype netmobiles. If the driver of a General Motors car equipped with its On-Star system locks his key in the car, for example, an emergency centre can transmit a digital signal to unlock the doors. On-star also calls automatically for help if an accident triggers the airbags. Toyota and General Motors are among a growing list of firms offering such in-car navigation systems. And in Europe, BMW and Mercedes-Benz recently introduced navigation hardware that can not only plot out a route, but alert a driver to traffic jams.
