Dear young musicians,

    Thank you for agreeing to take part in our Music Day. The whole idea of the day is for music students around the area to meet other players and receive expert teaching from our guests, six professional players. In the evening,you will perform the pieces you have worked on during the day at a concert which your friends and family can attend

    After you have registered（注册) at the reception,go to the main hall. First,there will be a short performance by our professional musicians who are joining us for the day. After this you will go into your classes to practice on your own instruments for the evening concert. There will also be a chance to experiment with a different institiment from the one you normally play,and see if you enjoy playing something more unusual — we have several instruments to choose from!

    The first part of the day will finish at 5 pm,when parents can collect students. For those remaining in the hall until the evening concert at 7 pm,there will be DVDs for you to watch,although you should also bring something to do while you are waiting. A change ot clothes is required for the evening — black trousers or a skirt and white top — so unless you are going home at 5 pm,you will need to have this with you at the start of the day.

    If for whatever reason you cannot attend the evening concert, you must tell us as soon as possible, as we need to know numbers in order to prepare the stage. We look forward to seeing you at the Young People's Music Day.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel stressed to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a "normal" part of society. This mindset helps them to learn a new language without feeling like they're doing something unusual or "too hard".

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    Imagine you went to a restaurant with a date, had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, "Hey Joe, how are you? Mary is over there in the seat you sat in last time. Would you like to join her for dinner again?" Then you find out that your burger has been cooked and your drink is on the table. Forget the fact that you are with another date and are on a diet that doesn't include burgers. Sound a little odd? To some, it is the same with the Internet. The Nets ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you--some of which you may not want them to have.

    Are you aware that almost every time you access a website you get a "cookie"? Unfortunately, it's not the Mrs.

    Reid's type. A cookie on the Internet is a computer code sent by the site to your computer--usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about your interaction, including where you visit, how long you stay there. How frequently you return to certain pages, and even your electronic address. Fill out a survey to collect free information or samples, and marketers know even more about you--like your name, address, and any other information you provide. While this may sound scary enough, cookies aren't even the latest in technology. A new system called I-librarian Alexa--named for the legendary third century.

    B. C. library in Alexandria, Egypt--does even more. While cookies track what you are doing at one site, Alexa collects data on all your Web activity, such as which sites you visit next, how long you stay there, whether you click on ads, etc. All this information is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don't even know that you are giving it.

    Our mother earth is going through a very tough situation and we, the entire human race, are destroying our environment consciously or unconsciously without even realizing its results. Now we have to act very smartly and plan something to sustain(保持) what we still have, getting all necessary support from nature to lead healthy lives.

    Gardening is always an excellent and environmentally friendly idea. If you can go for sustainable(可持续的) gardening, then it will be even more useful for all. Gardening is a favorite hobby for many. It is time to channelize your hobby towards a more meaningful motivation.

    When we do gardening we need to use different ingredients to grow plants. Some of the mare natural resources like water, soil, sunshine, and many things like this. Using these resources smartly is a part of sustainable gardening. Some simple techniques include: use less water and organic things to grow plants; try to store rainwater so that you can use them for gardening; try using less energy to drive devices; avoid using plastics in any form while gardening; reuse the leaves from your garden to fertilize them. These are the basic sustainable measures. To do so we need to have proper knowledge about gardening and its requirements so that we can use proper resources without wasting any of them.

    In today's busy life we don't get much time to spend on our environment. Gardening gives us a chance to do so. We can also have some pesticide-free and fresh food if we grow them in our garden. This is the right time to do some good to protect our own environment and gardening is one of the easiest ways. Do you want to start gardening, but you're not sure how?

    Last summer, bird-watchers confirmed the discovery of a new species of bird in Cambodia was not an event of particular biological significance, but it was striking for one reason in part. This species of bird was discovered not in an unspoiled rain forest but within the limits Cambodia's capital, Phnom Penh – a city the size of Philadelphia.

What the researchers found was surprising in cities. The medium-sized city in the state about 110 species of birds, over 95 percent of which would have been growing there urbanization. Ecologically speaking, cities are different, concrete buildings. Rather, each unique bio-profile – a kind of ecological fingerprint – that is against the idea of an environment dead zone.

    Of course, it's also true that in the world of birds and plants, as in human society, there is such a thing as worldwide—the city-inhabitants who feel equally at home in San Francisco, Milan and Beijing. Four birds occur in more than 80 percent of the cities studied, and 11 plants occurred in more than 90 percent of the cities. On the plant side, those are seemingly spread by European settlement. In the air, it's the usual suspects: the rock pigeon and many other birds. “They have become completely adapted to urban life,”Katti says. “That's not much of surprise. But they don't actually dominate as much as we think they do.” Those species—occurring in the cities across the globe—represent only a small part of a city's natural varieties.

    Not all cities are equal protectors of native animals and plants, though. One of the biggest predictors for a city's biodiversity is its urban design. Territory as varied as backyards and street trees can lay important roles in greening a city. In fact, the amount of green space is a stronger predictor of the density of biodiversity than a city's size. A metropolis with a sizable network of parks can contain more species per square mile than a much smaller city.

    In a world where architecture, food, language, fashion and commerce are increasingly globalized, a city's native animals and plants can be a kind of identity. There may be neighborhoods in London and Paris that resemble Singapore or Hong Kong. Cities are becoming similar, but their natural environments stand completely apart.

    While elephants born without tusks (长牙)are not unheard of，they normally form just 2 to 6 percent of the population. However, that is not the case at Mozambique's Gorongosa National Park, where an astonishing 33 percent of female elephants born after the country's civil war ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behavior expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivory.

    Poole says before the country's 15-year-long civil war, the 100,000-acre park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivory to help finance weapons (武器)and meat to feed the soldiers. Of the less than 200 survivors, over 50 percent of adult females had no tusks. Therefore, it is not surprising that the park's tuskless elephant population has grown greatly.

    This is not the first time researchers have observed a great change in the population of elephants. At Zambia's South Luangwa National Park and Lupande Game Management Area， areas which were heavily hunted in the 1970s and 1980s, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivory.

    The recent ban on ivory in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females, to change the trend.
