The old man walked with a cane (拐杖) slowly into the restaurant. His poor jacket, patched (打补丁的) trousers, and worn-out shoes made him stand out from the usual Saturday morning breakfast crowd. Unforgettable were his pale blue eyes that sparkled (闪光) like diamonds, large rosy cheeks, and thin lips that held a steady smile. He walked toward a table by the window. A young waitress watched him and ran over to him, saying, “Here, Sir. Let me give you a hand with that chair.” Without a word, he smiled and nodded a thank you. She pulled the chair away from the table. Supporting him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she pushed the table up close to him, and leaned his cane against the table where he could reach it. In a soft, clear voice he said, “Thank you, Miss.” “You're welcome, Sir.” She replied. “My name is Mary. I'll be back in a moment. If you need anything, just wave at me.”

    After he had finished a hearty meal of pancakes, bacon, and hot lemon tea, Mary brought him the change, helping him up from his chair and out from behind the table. She handed him his cane, and walked with him to the front door. Holding the door open for him, she said, “Come back and see us, Sir!” He nodded a thank you and said softly with a smile, “You are very kind!”

    When Mary went to clean his table, she was shocked. Under his plate she found a business card and a note written on the napkin, under which was a $ 100 bill. The note on the napkin read, “Dear Mary, I respect you very much, and you respect yourself, too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you.”

    The man she had served was the owner of the restaurant. This was the first time that she, or any of his employees, had seen him in person.

    After I mastered my first (协奏曲) at age 14, my parents decided to get me a nice violin. I tried out dozens of instruments before I found my match: a German violin. It was beautiful, but what I liked best about it was its voice. Confident and strong, it was everything I longed to be.

    I'm not sure how much that violin cost, but my parents made me promise never to let it out of my sight. They didn't understand that dragging a large violin case ran counter to my daily middle school task of being invisible (看不见的). I was a strange, absent-minded kid. When I spoke up in class, my comments brought confused silence from teachers and wild laughter from students. Like a deer in a wolf pack, I tried to be quiet and still.

    In contrast, my new violin was almost shockingly loud. Together, we could drown out the rest of my middle school orchestra(管弦乐队) — which was encouraged, since the other kids made sounds like cats' crying. For one glorious hour every day, I was showered with attention. Everyone wanted to hear what I had to say.

    Between classes, I bent under the combined weight of my violin case and a backpack filled with books. My posture suffered, but my confidence grew. With my violin by my side, I found my voice. More and more, I contributed to class discussions and even made a couple of friends.

    Today, I'm just an amateur violinist with a regular day job. As I sit in my community orchestra, sometimes I feel jealous(嫉妒的) my fellow musicians' instruments with their elegant voices. I may not be the best violinist around, but at least I'm still the loudest.

    Three-quarters of a million tourists flock to the primitive, white beaches every year—but this booming industry has come at a price. When foreigners left the government struggling to cope with a stream of rubbish, their answer was to turn one of these islands into a dumping ground. Clouds of sharp, poisonous smoke rising from open fires, piles of rubbish made up of plastic bottles, crisp packets and consumer junk. It's a far cry from the white sands, crystal-clear waters and gently swaying palm trees that we associate with the Maldives（马尔代夫）, the beautiful paradise island holiday destination set in the Indian Ocean.

    Of its 200 inhabited islands, which are spread across an area of 35,000 square miles, 99 are dedicated resorts. Three-quarters of a million tourists visit every year—more than double the domestic population. Of these, over 100,000 travel from the UK. The capital, Malé, is four times more densely populated than London. Given these facts, it's hardly surprising that the Maldives on which has a waste disposal problem.

    What you are seeing here is a view of the Maldives on which no honeymooners will ever fix eyes. Four miles west of Malé is the country's dumping ground, Thilafushi—or Rubbish Island as it has simply become known.

    The country dumps upwards of 330 tons of rubbish on the island every day, a figure attributed largely to the tourist industry on which the chain of islands relies. Each visitor generates 3.5 kg of waste per day.

    Now, the government of the Maldives has banned the dumping of waste on the island, which is too late, due largely to an increase in the number of waste boats “fly-tipping”（非法倾倒）directly into the sea, fed up with waiting seven hours or more to offload their cargo.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do.Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats.And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so­called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves.But this is believed to be one of the first studies highlighting the role of food in this relationship.Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product.The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such.They feel more trusting of those who consume as they do.It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”

    Harley Street psychologist Dr.Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust.But this was the first report that food had the same effect.She said, “This is really interesting.It makes sense as people feel they have common ground and can trust the other person.That means negotiations are more likely to be successful.”

    They're in restaurants, hotels and homes all over the world. The saltwater aquarium, with its colour fish, bring a piece of the wild into your living room.

    But do you really know where those saltwater fish come from? A full 97 percent, yes, almost all kinds of saltwater fish can't be bred in captivity (人工养殖). They must instead be taken from the ocean. And how is that done?

    Most of the time, with sodium cyanide, it is a harmful chemical compound that many fish collectors in the Philippines, Sri Lanka, and Indonesia use to catch fish. They mix it with water and use it on the fish. Stunned, the fish can then be easily caught.

    What does cyanide do to the fish? There is a scientific study on cyanide's effects. When there is cyanide in water, fish lose their balance and have difficulty breathing. Some fish simply die then and there. Many, many more die on the way to captivity.

    Although cyanide fishing in the Philippines, Sir Lanka, and Indonesia is not allowed, it still happens too often. According to the World wildlife Fund, up to 90 percent of the saltwater fish that enter the US each year are caught this way. The Center for Biological Diversity is calling on the US government to avoid these imports.

    “Compared to many environmental problems now facing the world's oceans, this is one that can easily be solved,” said Nicholas Whipps of the Center. “Because the US is such a powerful market player in this industry, the responsibility to stop this practice falls largely on the United State' shoulders.”

    In the Philippines, private planes bring in cyanide to the fisherman and then take away the live fish. Live fish give the fisherman a better life than dead ones, so more and more fishermen have turned from supplying the fish-for-food trade to the fish-for-aquariums trade.

    The Center for Biological Diversity hopes the government will use the law to turn away cyanide-caught fish and persuade people to buy those only raised in captivity.
