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.

    Dolphin or not a dolphin? That is the question! You see, there are several types of dolphins. Some are saltwater dolphins while others are river dolphins.

    "What are the 32 types of dolphins?" When people are asking the question, they are actually referring to the saltwater dolphins in oceans and seas. The river dolphins living in fresh water are not included in these species. But what would be the answer in this case if we ask. "Dolphin or not a dolphin?" The answer would obviously be yes. River dolphins still belong to the dolphin family.

    Among the 32 types of dolphins do not actually wear the word "dolphin" in their names, such as the tucuxi, while others actually have the word "whale" as part of their names even if they are not whales but in fact, belong to the dolphin family, for example, the melon-headed whale and the killer whale. So what would be the answer to the question "Dolphin or not a dolphin?" in these cases? It would be yes. All these species do belong to the dolphin family.

    Another question that people ask is. "Are the sea animals that perform at aquariums(水族馆)all dolphins?" So ,it always seems to come back to the question, "Dolphin or not a dolphin?" Well the answer is no in this case. The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile, like most dolphins, are in fact a species of the whale family.

    Now that you read these facts about dolphins, you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case, it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin. That is the question ！

    If Confucius(孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

    While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

    But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually include Chinese art, history and philosophy(哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks of Western philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

    So the old thinker's ideas are still alive and well.

    Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

    As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    Play time is in short supply for young children these days and the lifelong consequences for developing children can be more serious than many people realize.

    An article in the most recent issue of the American Journal of Play details not only how much children's play time has declined, but how this lack of play affects emotional development, leading to the rise of anxiety, depression, and problems of attention and self control. “Since about 1955, children's free play has been continually declining, at least partly because adults have applied ever-increasing control over children's activities.” says the author Peter Gray, Ph. D, Professor of Psychology at Boston College.

    We can describe the unstructured freely-chosen play as a testing ground for life. It provides critical life experiences without which young children cannot develop into confident and competent adults. So kids need more of it, not less. Because play is how young children learn important social and emotional skills such as sharing, cooperating, communicating, and empathizing. It helps them develop fit bodies, strong minds, and brave hearts, so they can take on new challenges and risky situations.

    Gray's article is meant to serve as a wake-up call regarding the effects of lost play. We must know that lack of childhood free play time is a huge loss that must be paid attention to for the sake of our children and society. But parents who keep a lookout over and disturb their children's play are a big part of the problem. It is hard to find groups of children outdoors at all, and, if you do find them, they are likely to be wearing school uniforms and following the directions of coaches while their parents dutifully watch and cheer.

    Actually, when children are in charge of their own play, it provides a foundation for their future mental health as older children and adults. Play gives children a chance to find and develop a connection to their own self-identified and self-guided interest. It is through play that children first learn to make decisions, solve problems, improve self-control, and follow rules. Play helps children make friends and learn to get along with each other as equals. Most importantly, play is a source of happiness.

When parents realize the major role that free play can take in the development of emotionally healthy children and adults, they may wish to reassess the priorities ruling their children's lives. The needs for childcare, academic and athletic success and children's safety is important. But perhaps parents can begin to identify small changes——such as openings in the schedule, backing off from quite so many supervised (有监督的) activities, and possibly slightly less keeping watch on the playground that would start the slow returning to the direction of free, imaginative-directed play.

    It's 11 p.m., and I'm still sitting here writing this article for the school magazine! I've had two weeks to write it, and my teacher, Julia, wants it tomorrow. She's always complaining (抱怨) that I leave things till the last minute. Maybe she's right.

    A month ago I made a decision to be more efficient (有效率的) this year. Well, I've clearly failed. I've also been trying to get fitter for four weeks now. I've started going to the health club. I've even been going to bed earlier. But I'm not feeling any fitter, just a little unhappier. I miss my bad habits. Why is leading a better life so hard?

    I've just read an article on a website, and I've discovered that it isn't my fault (过错)! In fact, it isn't anyone's fault. It's our brain's. It's programmed to make it difficult to break bad habits. There's nothing we can do. Scientists have done experiments that show we use one part of our brain when we think about ourselves and another when we think about other people. However, when we think about ourselves in the future, we use the same part of the brain that we usually use to think about other people. In other words, the brain sees the “future you” as a different person than your “present you.” That's why we don't always find it easy to make good decisions for ourselves in the future.

    But that's not all. Scientists have also discovered that it takes around ten weeks to form a good habit. That's the amount (数量) of time the brain needs to accept new behavioral patterns (形式). The good news is that once you make it to ten weeks, everything becomes a lot easier. The bad news is that ten weeks is a really long time, so it's easy to give up what you want to do before then.

    So even when we want to change our ways and become better people, our brains won't let us. Or is this just an excuse? Look — I've finished my article on time! Anything is possible!

Socially, few things are more annoying than someone repeatedly checking their phone in the middle of your conversation with them. Soon enough, you're having unhappy thoughts, thinking of their way like, I'm boring you; you're more concerned with whoever's on that phone than me; you don't care about me. None of that is necessarily true, but this is: "If someone is engaged in a great conversation, they wouldn't care about their phones," says Leslie, a psychologist and researcher at NYU.

Do you sometimes wonder: What should I have said to a rude person like this? What if we have to talk to such maddening persons? Experts have advice about how to deal with this.

Whether you say something or not, remember that the cell-addict's annoying habits aren't about you. "It's rude, for sure, but sometimes we mistake the behavior for more than what it is," says Leslie. "It's possible that they are facing something tough and merely experiencing nervousness or anxiety," he adds. It's also possible that their partner is stuck with a flat tyre (轮胎) or their kid is sick in hospital. The point is that you don't know.

So before you become angry at the cell-addict's open rudeness, focus instead on building a better conversation than whatever's going down on Instagram. You might never be able to achieve this, given the power of today's social media, so if you're close enough to a person, Leslie advises you to directly ask them: "What's on that thing that's so interesting?" Chances are that they will apologise at once and quickly put the phone away. But if the answer is something real, talk about it. Better yet, you can avoid the situation in advance by saying something like, "I'm really interested in catching up properly, so how about we leave our phones in the car?" If they indeed have that flat tyre or sick kid, at least you won't have to assume that it's because your stories are boring.
