You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    It was December 25, 1914, only 5 months into World War I. German, British, and French soldiers, already sick and tired of the senseless killing, disobeyed their superiors and started socializing with "the enemy" along two-thirds of the Western Front.

    German troops held up Christmas trees with signs, "Merry Christmas". Thousands of troops ran across the battlefields covered with dead bodies. They sang Christmas songs, exchanged photographs of loved ones back home, shared food and even played football. Soldiers hugged men they had been trying to kill a few short hours before. They agreed to warn each other if their officers forced them to fire their weapons, and to aim high.

    Fear ran through the military leaders on both sides. They felt that their power was being challenged: soldiers declaring their brotherhood with each other and refusing to fight. Generals declared this unexpected peacemaking illegal and said that participating soldiers would face a military court. Those found guilty would be imprisoned or even shot. By March 1915 the socializing movement had been destroyed and the killing machine was back in full operation. Over the next three years more than fifteen million people died in the war.

    Not many people have heard the story of the Christmas Truce (休战). On Christmas Day, 1988, a local radio host in Boston played "Christmas in the Trenches", a song about the Christmas Truce several times and was stunned by his listeners' response. Thousands of people called in, praising the song, with many moved to tears by the amazing events it described.

    You can probably guess why the callers were in tears. The Christmas Truce story goes against most of what we have been taught about people. It lets us see the world as it can be and says, "This really happened once." It shows us the potential we have as humans contradicts all of those TV and newspaper stories that tell us how mean and heartless people are. It is like hearing that our deepest wishes really are true: the world really can be different.

    Buster used to be a lovely dog playing and running on a farm all day. His life had a big change after his handler Will's presence because Will found he did extremely well in sniffing tests. Will thought Buster had a special talent and decided to let him become a member of RAF police working dogs. Buster began working with Will in 2007, and the pair was sent to Afghanistan's deadly Helmand province. There, Buster saved countless lives by sniffing out explosive devices (IEDs), as well as weapons. He joined his comrades repeatedly on foot patrols hunting Taliban terrorists and tracking down bombs. He also acted as a useful diplomatic tool, due to his friendly approach to local children. The RAF soon had a long train of children in tow, as Buster drew in his crowd and entertained them.

    After his glittering service with the RAF, Buster retired in 2011,and died in 2015 at the age of 13 at the home of his handler, Will, in Lincolnshire where he had been enjoying retirement with his handler Will, his wife Tracy and their two dogs who will inherit (继承) their father's career.

    Over the course of his career, Buster is thought to have saved more than 1,000 lives. He also helped patrol British bases and searched vehicles at check points, and upon retirement was made the official RAF Police mascot (吉祥物). Buster's brave exploits were even documented in Will's book, which was published in January and soon became a best-selling one.

    Buster completed five tours of duty in Afghanistan, Bosnia and Iraq and earned a row of campaign medals, and it was because of his great efforts in these austere environments full of wars and confrontations that he would be remembered. It was the saving of countless lives by searching out IEDs that saw the honor of official lifetime mascot of the RAF Police bestowed (授予) upon Buster. The RAF police are now planning to commemorate Buster as part of a special event to celebrate RAF Police Working Dogs.

More than 400 athletes across a variety of sports, ages and levels of experience were questioned for the study by sports psychology experts from Staffordshire University and Manchester Metropolitan University. The findings reveal that athletes' belief systems—specifically irrational（非理性）beliefs—are related to poorer self-confidence, and in turn, greater competitive anxiety and depressive symptoms.

"Phrases that reflect self-depreciating（贬低）beliefs such as ‘If I lose, I'm a failure' or ‘If I face setbacks, it shows how stupid I am' are warning signs," said the authors. Paul Mansell, Lecturer in Sport and Exercise Psychology at Staffordshire University, said, "Despite the psychological benefits of physical activity, studies frequently report poor mental health in athletes, which may be exacerbated by adversities, such as injury, de-selection, and performance pressure. We investigated athletes' beliefs, how they view stress, their levels of self-confidence and put all this data together to work out what might predict psychological well-being. We found irrational beliefs to be a core reason for symptoms of poor mental health in athletes."

This is the first known study that has examined irrational beliefs, self-confidence, and the psychological well-being of athletes all together. Irrational beliefs are extreme, rigid, and illogical ideas that people hold. For example, a person might believe that they "must" get what they want, or that just because they have failed, they are a "complete failure".

"We can all work to help athletes develop mindsets that help them deal with the challenges of sport and life. By encouraging rational and logical beliefs about performance, we can help athletes to stay healthy amidst the high demands of competitive sport," said Paul Mansell.

The author s propose Rational Emotive Behavior Therapy（REBT）as an effective tool for protecting self-confidence. REBT helps athletes to challenge these self-depreciating beliefs and develop beliefs that are more helpful and healthy. For example, rather than believe "I am a failure if I fail", this might be countered with "Failing is not ideal, but it does not mean that I am a failure".

Nowadays, the term "superfood" has become the nutritional buzzword. Simply put, these superfoods are those that provide large amount of nutrients through minimal calories. 

The term "superfood" may have taken the modern food scene by storm. {#blank#}1{#/blank#} Although only popular in recent years, the concept of certain foods with special nutritional qualities has been around for a long time. The nickname "superfood" gained widespread popularity in the early 2000s as health enthusiasts and the food industry sought to identify and market foods with special health benefits. Today, it is a trend in diet. 

In an age when we share all kinds of superfoods on social media, ignoring the phenomenon is impossible. {#blank#}2{#/blank#} It's easy to understand. These nutritional superheroes offer a perfect combination of substance and style, tailored for the digital generation. Their lively colours, exotic origins and impressive nutrient profiles make them candidates for the next viral food trend. 

{#blank#}3{#/blank#} They offer a lifestyle that reflects the global shift towards a more healthconscious society. As the world wrestles with an increasing burden of diseases and the fast pace of modern life, people are seeking dietary solutions from superfoods. {#blank#}4{#/blank#} They are rich in vitamins and minerals that can strengthen your immune system, avoid chronic diseases, and improve your overall wellbeing. Another remarkable benefit is their potential to promote heart health, helping you build a strong heart. Don't forget their role in skin regeneration. The antioxidants(抗氧化物) can provide a natural glow, reduce skin ageing and fight against skin conditions. 

{#blank#}5{#/blank#} Superfoods, while nutritionally dense, should be part of a comprehensive diet rather than the only guarantee of our health.
