As the saying goes, “Without music, life would be a mistake.” Music is very important in our lives and here are four of the greatest musicians in history.

    Ludwig van Beethoven(1770-1827)

    Born in Bonn, Germany, Beethoven never held an official position in Vienna. He supported himself by giving concerts, teaching piano, and the sale of his compositions(作曲). The last 30 years of Beethoven's life were filled with a lot of hard times, the first of which was his deafness. Beethoven's music greatly influenced the next generation of musicians.

    Johann Sebastian Bach(1685-1750)

    Bach, “the father of modern music”, was born in Eisenach, Germany. His parents died when he was nine years old, and in 1695 he went to live with his brother Johann Christoph, who was an organist(风琴手) in Ohrdruf. He stayed there until 1700. Seven years later, he moved back to Weimar, where he served as court(宫廷) organist for nine years. His music greatly influenced classical music.

    Frederic Chopin (1810-1849)

    Chopin was born in Zelazowa Wola, Poland. He showed a talent for the piano at a very young age. Chopin began composing when he was still a child, but some of his early works have been lost. He gave his first public concert in 1818. Chopin was considered as the leading musician of his time.

    Franz Schubert(1797-1828)

    Schubert was born and died in Vienna. Unlike most of his predecessors(前辈),Schubert was not a great performer. He never had much money but he was very productive. He wrote his first masterpiece when he was only sixteen. However, he died young, before his talents had even been known.

    Of all nature's disasters, forest fires are often considered the most frightening. Moving at lightning speed, huge walls of flames can burn acres of land in just a few minutes. And although technology, including the use of fire-retardant chemicals, has greatly helped the fight against forest fires, they still do great damage.

    According to the National Interagency Fire Center, the fire season last year was the worst on record in terms of the number of fires and acres burned. There were 96. 385 fires and 9.873429 acres affected by fire in a year that was 125% more destructive(毁灭性的) than the10-year average. These fires cost the federal government $1.5 billion to fight, and this figure does not include the money spent by local and state governments as part of the effort.

    Fires in the southern states represented half of the national total last year with Texas, Oklahoma and Arkansas being home to a usually high amount of activity. Wildfire has also taken place in Western states such as California, Colorado and Alaska throughout the past 10 years.

    It is said that two-thirds of forest fires are started accidentally by people. Almost one quarter are purposely set, while lighting causes 10%.

    Forest fires can have advantageous effects. Charcoal(木炭) enriches soil and some plant species(种类) grow well after fire. The cones of the jack pine tree, for example, will not spread their seeds unless there is heat. Douglas fir trees grow best in open sunlight areas after fire.

    A gaming company in New Zealand is luring employees from around the world by offering unlimited paid annual leave, a share in the company's profits and no set work hours.

    Dean Hall became famous in international gaming circles for being the lead designer on popular video game DayZ. After searching the world for a location for his new gaming studio, Rocketwerkz, New Zealander Hall settled on the small university town of Dunedin on the south island's east coast, where land is cheap and creative start-ups have become an important pan of the city's identity.

    Rocketwerkz's flexible work culture is now drawing talent from around the globe, with Hall receiving 300 messages of inquiry since a local newspaper wrote about his studio last week.

    Last year, when the company was still in its infancy(婴儿期), baby cats would also make a regular appearance in the office as a form of fighting stress, and Friday afternoons are generally reserved for sports and games to end the week on a playful note.

"The first time I heard about the idea of unlimited paid leave in places like Silicon Valley it was about the problems it caused. A culture had appeared where employees took no leave," said Hall.

"So to address that, our staff are issued the standard New Zealand annual leave of four weeks, but they can also take unlimited leave in addition to that."

    Emily Lampitt, from Britain, is a 3D junior artist who has been with the company for a year and a half. She says the flexible work culture was a huge factor in her decision to move to New Zealand.

"The flexibility here has made me feel much more relaxed" she says. I "That internal stress I used to feel in a traditional work environment has gone, so when I am at work now it is because I want to be, because I am passionate(有激情的), not because I am afraid of my boss or watching the clock."

    Cassie Warren and Jesse Jones will always have a great story to tell their kids about the kindness of strangers and how one stranger in particular made their wedding planning that much sweeter.

    A few weeks ago, as Warren was addressing wedding invitations for her upcoming wedding, she mistakenly used an old address for her aunt and uncle in nearby Eugene, Oregon. But when a stranger received the misaddressed mail, she didn't just throw it in the garbage like many people would have done. Instead, she returned the invitation, along with a sweet note and $20 as a wedding present.

The sender also wrote "Live long and prosper." on the comer of the card—words from "Star Trek", probably because the young couple's wedding invitation shows Jesse holding a light knife from "Star Wars" and Cassie holding a wand (魔杖) in a nod to the "Harry Potter" books.

    The generous stranger also included $20, probably as a little gift for the wedding. The young couple put the money to good use by going out to dinner with a friend who wouldn't be able to attend the wedding.

    Warren said that she was at first confused by the returned wedding invitation. "But after I saw the note, I was just surprised and blessed that she/he would do that for a stranger," Warren said. "Jesse was confused at first, too-he wondered why someone had sent us money, then I read the message to him, and he was shocked and grateful."

    Warren and Jones still don't know the name of the kind stranger, but Warren sent a thank-you note to the same address to let the sender know how much her/his generosity was appreciated. The young couple plan to marry in June and thanks to the kindness of a stranger, their marriage is already off to a sweet start.

    A killer whale(虎鲸) that can copy words such as “hello” and “bye-bye” is thought to be the first of its kind to copy human speech.

    The female killer whale learned to “speak” some human words by copying a trainer at a park in France. The animal's ability includes speaking the name “Amy” and “one, two, three”.

    Whales and dolphins are among the few animals except humans that can learn to produce a sound just by hearing it. “It is not often seen,” said Dr Josep Call, a co-researcher on the study. “Humans are good at it…Interestingly, the animals that can do best are marine mammals(海洋哺乳动物).” The researchers start to find out whether killer whales could learn new words by copying others. They studied a female named Wikie at Marineland Aquarium in Antibes, France. She was taught to speak human words.

    Dr Jose Abramson, a co-researcher on the study, said basic “conversations” with Wikie may one day be possible. He said,” It has been done before with a famous grey parrot and dolphins using American sign language(手势语).” However, he said they have to be careful about introducing human ideas on animals, as there is more to learn by trying to understand the natural way each kind communicates in its own environment. Wikie made sounds in water, which may be quite different.

    Dr Alex Thornton, senior speaker at the University of Exeter, said they still don't fully understand why some animals learn to copy. Some animals copy sounds to attract possible partners, while others copy sounds to become a member of a group. “Some whales, for example, learn their calls from one another to mark them out as members of their social group,” said Dr Thornton, who doesn't join in the research.

    Last year, I lived in Chile for half a year. I lived with a Chilean family and had the responsibilities of any Chilean teenager. I had good days and bad days I didn't understand.

    Chuquicamata, my host community, is a mining camp. When I arrived there, I was scared. It was so different from what I was used to. There were lots of dogs on the streets, and there was no downtown, few smoothly paved streets, and little to do for entertainment. Rain was not seen very often, earthquakes and windstorms were frequent.

    I had studied Spanish for two and a half years and was always one of the best students in my class. But in my first week in Chile I was only able to communicate and needed one person to whom I could explain my shock. I couldn't speak the thoughts in my head and there were so many.

    Most exchange students experience this like me. Culture shock presents itself in everything from increased aggression towards the people to lack of appetite (食欲). I was required to overcome all difficulties.

    As time passed, everything changed. I began to forget the words in English and to dream in Spanish and love Chilean food. I got used to not depending on expensive things for fun. Fun in Chuquicamata was being with people. And I took math, physics, chemistry, biology, Spanish, art, and philosophy.

    But the sacrifices were nothing compared to the gain. I learned how to accept and to succeed in another culture. I now have a deeper understanding of both myself and others.
