Article: I was dirty smelly hungry and some somewhere beneath all that, suntanned .It was the end of an Inter-Rail holiday.My body couldn't take any more punishment. My mind couldn't deal with any more foreign timetables, currencies or languages. " _ ," I said, as I stepped onto home ground.I said exactly the same thing the following year.And the next, all I had to do was buy one train ticket and, because I was under twenty--five years old,I could spend a whole month going anywhere I wanted in Europe. Ordinary beds are never the same once you've learnt to sleep, in the passage of a train, the rhythm rocking you into a deep sleep. Carrying all your possessions on your back in a tucksack makes you have a vefy basic approach to travel,and encourages incredible wastefulness that can lead to burning socks that have become too anti-social ,and getting rid of books when finished.On the other hand, _ is entirely in the spirit of Inter--Rail,for common sense and reasoning can be thrown out of the window along with the paperback book and the socks.All it takes to achieve this carefree attitude is one of those tickets in your hand. Any system that enables young people to travef through countries at a rate of more than one a day must be pretty social on that first trip,my friehds mad I were at first unaware of the possibilities of this type of train ticket,thinking it was just an inexpensive way of getting to and from our chosen camp-site in southern France.But the idea of non-stop travel proved too attractive,for there was always just one more country over the border,always that little bit further to go.And what did the extra miles cost us? Nothing. We were not completely uninterested in culture.But this was a first holiday without parents,as it was for most other Inter-Railers,and in organizing our own timetable we left out everything except the most available sights.This was the chance to escape the guided tour,an opportunity to do something different.I took great pride in the fact that.in many places,all I could be bothered to see was the view from the station.We were just there to get by,and to have good time doing so.In this we were not different from most of the other Inter-Raiders with whom we shared passage floors,food and water,money and music. The excitement of travel comes from the sudden reality of somewhere that was previously just a name.It is as if the city in which you arrive never actually existed until the train pulls in at the station and you are able to see it with your own tired eyes for the first time.

Article: Graham and his friends preferred to shoot up in their arms, necks and legs. A dealer once said Graham was the type who would never be able to turn back and that he expected him to die from the drug. Wendy feared the same, but didn't know how to save her son. " Once, after he'd disappeared for more than a month, I found him at a friend's house with a bunch of other users," she said, "I got down on my hands and knees, begging him to come home. He did, but the next morning he was gone. I don't know what made him do it, but I drove 20 miles to the nearest train station. Graham was headed for Seattle, his pockets full of drugs. If I hadn't gotten there in time, I would never have seen him alive again." The turning point came in 2007, after Graham was arrested yet again for possession. Wendy got a call from the Montana Drugs Project, which works with local law enforcement to keep track of youth-related crimes so it can help families in trouble. Following a counselor's advice, Wendy hired two men to come to her home in the middle of the night, tie Graham and take him to a treatment program in Thompson Falls, Montana. "I was high when they came and really angry with my mom," he said, "But if she hadn't done that, drugs would have killed me." After six months of treatment, Graham, now 19, came back to Kalispell, where he's grown close to Wendy once again. "I still have the desires every day and attend support meetings every night," he said, "But life is worth living again. My mom thinks that's a miracle. I guess she is right."

Article: When you turn on the radio, you hear an advertisement. 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. As a result, advertisements are almost everywhere. 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 not be these private businesses. Have 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, non-personal, and usually persuasive description of goods, services and ideas by identified sponsors through various media. First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is non-personal. 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 and nontraditional mass media. Included in the traditional media are newspapers, magazines, radio, television, and films. Nontraditional media include the mail, matchbox covers, and billboards.
