Friendship Day is celebrated every year on the first Sunday in the month of August. People give their loved ones or friends friendship bracelets (手镯) and other gifts to celebrate their friendship. The culture of friendship bracelets is as old as even thousands of years.

    After the World War II, the paracord (伞绳) bracelets became very popular. These were also known as survival bracelets. One of the main reasons is that it was often used for a rescue purpose. Paracord, used in the parachute, does not wear away easily and is strong and durable. Because of its light weight, people could carry it along easily. If required, it could be made a very long rope and be used as a rescue rope. Hunters used it to find their way that they could return without getting lost.

    Today there are all kinds of paracord bracelets, made of coloured strings. Girls like thinner and colourful bracelets. Many choose to make the bracelets by themselves for their dear friends. This not only appeals more to the feelings of people but also makes them know how much their friends mean to them. People keep the bracelets given by their friends long. Many people choose coloured strings keeping the depth of their friendship in mind. White, yellow, orange and red show the different levels of friendship. Pure friendship is shown in white; the red colour means love. An orange friendship bracelet is given to show strong friendship and yellow as simple friendship. Today, not only do the young people show these friendship bracelets, but even the old do.

    Does friendship have an age? Yes. Friendship is like the wine, and the older you get, the older and stronger your friendship is.

Dear Derrick ,

    Although under great pressure, we all get on well with each other in this large office. You are one of the people who keep the social temperature at such a comfortable setting. I don't know anyone in the office who is better liked than you .

    You can perhaps help with this. The collection of contributions towards gifts for employees' personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two weeding gifts, one funeral remembrance, four birthday gifts, and three graduation gifts .

    It's not only the collected-from who are growing uncomfortable(and poor), but the collected-for feel uneasy receiving gifts from people who don't know them outside the office, who wouldn't even recognize their graduating children, their marrying daughters and sons, or their dead relatives.

    This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today's office setting .

    Thank you for understanding .

    Wetlands are ecosystems found in low, flat areas. Often they border ponds, rivers, lakes, and oceans. Wetlands include marshes, swamps, and bogs.

    No trees grow in a marsh, but there are lots of grassy plants. Ducks, turtles, and many different bugs (虫子) live there, too. Florida has the world's biggest freshwater marsh. The Everglades covers 4,000 square miles. The Everglades is not entirely fresh water, however. Near the sea the fresh water and salt water mix. Some plants and animals can live only in this brackish water.

    Saltwater marshes lie along the East Coast and the Gulf of Mexico. During high tide these marshes are under water. During low tide these marshes can be seen. The water rushes out, carrying bits of plants, dead animals, and minerals necessary for sea animals. Many plants and animals depend upon this ever-changing environment.

    Swamps are forested wetlands. Like marshes, they are often found near rivers or lakes and have mineral soil that drain very slowly. Unlike marshes, they have trees and bushes. Swamps have trees that grow with their roots underwater. But the trees will die if their roots stay underwater too long. Animals such as water snakes and frogs live in swamps.

    Bogs have damp, soft soil. So many dead plants have piled up that there is no longer any standing water. This rotting plant matter turns into peat (泥炭). In Ireland and Scotland peat is dried and burned to heat homes. Bog soil is useful for growing wild rice. Lots of insects live there.

    Most people do not find wetlands beautiful. But wetlands are important. Marshes and swamps store water, thus reducing the flooding a heavy rain can cause. About one-third of all of America's endangered plants and animals live in wetlands. Now laws protect some wetlands. More than a dozen wetlands in the US are refuges (保护区) and wildlife preserves.

    When Cherry Watson travelled on a recent flight from New York to Washington and noticed an 'awful tension' in the cabin, she first thought it was caused by typical bad-tempered passengers. But as the flight neared its end, it became obvious that something was very wrong.

    A teenage boy with Down Syndrome (唐氏综合症) who was traveling with his family had become upset and would not return to his seat, regardless of the cabin crew's warnings over the loudspeaker that it was almost time to land. The pilot was forced to circle above the airport, delaying the landing and angering people on the already tense flight.

    'If it was a cartoon,' remembered Watson, 'there would have been smoke coming out of people's ears.'

    The boy's elderly parents and adult brothers and sisters tried to persuade him to get off the floor and back into his seat, but in vain. Watson, who used to be a teacher, stood up and quickly headed to the back of the plane.

    She found the boy in the passage between rows of seats, lying on his belly, and lay down on her stomach to face him. She began chatting calmly with him, asking his name, his favorite book, and his favorite characters. He told her he felt sick and she tried to comfort him.

    Minutes later, he allowed her to hold his hand, and then together they got properly back into airplane seats. Watson asked for sick bags, and held them as the boy threw up several times, including on her. As she helped him clean up, she repeatedly told him everything would be okay and that they'd get through it together.

    After the plane was finally able to land, no one was impatient to step off the flight as one might expect. Instead, calmed passengers—obviously following Watson's amazing example—allowed the boy and his family to depart first, smiling at them as they passed. His parents tearfully thanked Watson for what she had done, and a doctor sitting nearby also let her know he had even taken notes on her expert way of handling the situation.

    Do you believe in the power of music? If you're like most kids these days, you probably have an electronic device loaded with hundreds or even thousands of your favorite songs. At any moment in time, you can fill your headphones with the sounds of a particular song that suits your mood at that exact time.

    Are you getting ready for a big soccer match or do you need to get excited? Maybe some hip hop with a strong beat will do the trick! Besides, you might be ready to study for a big exam the next day. To calm your nerves and help you concentrate, a little bit of Mozart might make memorization more manageable.

    But is there any scientific evidence of these effects that music seems to have? You bet there is! Scientists have long recognized the power of music. Over the years, many studies have been conducted to examine in greater depth the nature and extent of the effects music has on people.

    For example, scientists at the University of Missouri have found that listening to music can have a positive effect on your mood. Their research gives scientific credibility(可信性) to the behavior that many people have already experienced on their own: listening to upbeat music can brighten your day and boost your mood.

    Other studies have shown that upbeat music isn't the only type of music that can be helpful, however. When people are sad or have suffered a personal loss, sad music can be helpful because people identify with the tone and lyrias(歌词) of the music. Likewise, people under a lot of stress or experiencing upsetting situations can benefit from listening to angry music. Although angry music might not help you if you're in a normal mood, its tone can benefit you when you are dealing with stressful and upsetting situations.

    Across Europe, where visitors can outnumber residents in the summer months, the complaints have started. Last week, in Barcelona, an open-top bus was spray-painted across its windscreen with the words “Tourism Kills Neighbourhoods”. The message is clear: such cities are under pressure. In tourists and residents' battle for shared spaces, local authorities are uncomfortably in the middle. The tourism is one of the largest employers in the world, with one new job created for every 30 new visitors to a destination—but at what cost to locals' quality of life?

    More people are travelling than ever before, and lower barriers to entry and falling costs mean they are doing so for shorter periods. The rise of “city breaks”—48-hour bursts of foreign cultures—has increased tourist numbers. “Too many people do the same thing at the exact same time,” says Xavier Font, a professor at the University of Surrey, “For locals, the city no longer belongs to them.”

    Compounding the problem is Airbnb, which has made tourists more casual in their approach to international travel, but added to residents' headaches. Those permanent citizens who share their apartment blocks with Airbnb hosts have lost their patience, “No longer do we have to share the streets with tourists, we have to share our own buildings!” To ease the congestion around the main attractions, many cities are taking immediate action. Venice is proposing a new concept of “detourism”: sustainable travel tips and alternative routes for exploring a different Venice. A greater variety of guidance for future visitors—ideas for what to do in off-peak seasons, for example, —can guide them from overcrowded landmarks. Repeat visitors have a better sense of the culture and it is much easier to integrate their behaviour with residents of the cities.

    “But the locals should learn to take tourists as a part of urban life. Tourists do not have to be considered passive players, but rather as visitors with rights and duties,” says Font, “Everyone has a part to play in promoting that change.”
