The word advertising refers to any kind of public announcement that brings products and services to the attention of people. Throughout history, advertising has been an effective way to promote(促进)the trading and selling of goods. In the Middle Ages, merchants employed "town criers" to read public messages aloud to promote their goods. When printing was invented in the fifteenth century, pages of advertisements(ads)could be printed easily and were either hung in public places or put in books.

    By the end of the seventeenth century, when newspapers were beginning to be read by more people, printed materials became an important way to promote products and services. The London Gazette was the first newspaper to set aside a place just for advertising. This was so successful that by the end of the century several companies started businesses for the purpose of making newspaper ads for merchants.

    Advertising spread quickly throughout the eighteenth century. Ad writers were starting to pay more attention to the design of the ad text. Everything, from clothes to drinks, was promoted with clever methods such as repetition of the firm's name or product, words organized in eyecatching patterns, the use of pretty pictures and expressions easy to remember.

    Near the end of the nineteenth century, companies that were devoted to the production of ads came to be known as "advertising agencies(广告商)．"The agencies developed new ways to get people to think of themselves as members of a group. Throughout the twentieth century, advertising agencies promoted consumerism(消费主义)as a way of life, spreading the belief that people could be happy only if they bought the "right" products.

    On a cool morning, Wilson Kasaine heads out along a dirt path in southern Kenya. His calmness makes it easy to forget that he's tracking one of the most dangerous animals in the world. Kasaine is tracking lions—especially one lion called Marti, who is the real-life Lion King of Selenkay Conservancy.

    Tracking lions on foot may sound like a death wish, but Kasaine has been doing it for most of his life. Born into a traditional Maasai family he quickly grew to understand the beauty and danger of wildlife. Living with big wild animals forces him to develop a good sense of where they have been and where they may be going. During his 12-kilometer walks to and from school, he learned how to tell the paw prints (爪印)of a lion from those of other animals.

    Growing up, Kasaine knew that improving his tracking abilities would help him avoid surprise meetings with dangerous animals. For many Maasai, tracking is mainly a matter of self-protection. But Kasaine is tracking lions to meet them and to protect them. He leads a small group of wide-eyed tourists over the red sandy path, searching for the lion that has left upon it his prints.

Each year, thousands of tourists crowd Kenya's national parks to try to have a look at the"big five”; elephants, rhinoceros, leopards, buffaloes and lions. The international draw of these animals matters a lot because the nation's economy is tied to the protection of its wildlife. If Kenya's wildlife disappears, so does its second-largest source of income.

    Wildlife protection efforts in Kenya meant marking off land exclusively(专门地)for animals. But it also meant that the people who had originally lived in the area were forced to leave their land and into smaller surrounding areas. They are also finding it increasingly hard to keep a traditional Maasai lifestyle. But people are glad that it really makes a difference to wildlife protection.

    A young and successful manager was traveling down a neighborhood street, going a bit too fast in his new Jaguar.

    As his car passed a park, one child appeared, and a brick smashed into the Jaguar's side door. He stopped the car very suddenly and drove the Jag back to the spot from where the brick had been thrown. He jumped out of the car, grabbed some kid and pushed him up against a parked car, shouting, "What was that all about and who are you? Just what on earth are you doing? That's a new car and that brick you threw is going to cost a lot of money. Why did you do it?"

    "Please, sir, please, I'm sorry. I didn't know what else to do!" begged the youngster. "It's my brother," he said. "He fell out of his wheelchair and I can't lift him up."

    Sobbing, the boy asked the executive, "Would you please help me get him back into his wheelchair? He's hurt and he's too heavy for me."

    Moved beyond words, the driver tried to swallow the rapidly swelling lump(隆起的肿块)in his throat．He lifted the young mail back into the wheelchair and took out his handkerchief and wiped the scrapes(擦痕)and cuts, checking to see if everything was going to be okay.

    "Thank you, sir. And God bless you, "the grateful child said to him. The man then watched the little boy push his brother to the sidewalk toward their home.

    It was a long walk back to his Jaguar... a long, slow walk. He never did repair the side door. He kept the dent(凹痕) to remind him not to go through life so fast that someone has to throw a brick at you to get your attention.

    Life whispers in your soul and speaks to your heart. Sometimes, when you don't have the time to listen... Life throws a brick at your head.

    It's your choice: Listen to the whispers of your soul or wait for the brick!

    More and more comments sections are being shut down online.

    Autumn Phillips had had enough. On Aug. 19, the executive editor of the Quad- City Times in Iowa, and Illinois, US visited her website, qctimes.com, and saw a story about a man who had been shot to death. When she got to the readers' comments sections at the end, she was shocked by what she saw. Below the story was a growing number of comments—a racist remark about democratic votes, a negative comment about police …So Phillips decided to do something she had been thinking about for a long time: she shut down the comments sections.

    Phillips was not alone in making such a move. Last week, NPR announced k too was closing its online comments sections. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In early days of digital journalism, comments were seen as a key part of this new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolution. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    "Since we made the announcement, I've received an outpouring of responses from our readers," she says. "I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and wasn't worth it."

    Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter?

    More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language.

    You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer.

    Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and the State University of Campinas are both highly ranked internationally. Your money will go a long way there, too.

    Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.
