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.

Dear John,

    My name is Amber and I want to share my story with you because what you've shared about life and positive energy has changed my life. This past year has been one of the hardest for me. I felt I was stuck in a position that had nothing to do with what I wanted to do with my life. In January, after two years of being together, my boyfriend left me.

    I read your blog every morning as I drink my coffee at work, but it wasn't until this March that I told myself "no more negativity" as you taught readers in your blog.

    Since then I've got into new habits at work to keep my energy positive. When people walk in the front door, I'm the first face they see, so I smile big when I say "good morning" to them, especially on Mondays. Instead of waiting for someone to ask me for help, I offer it with an open mind. The CEO noticed my change and offered me the executive assistant position that I wanted.

    One of the biggest things I've taken to heart from your blog is changing my opinions on my job. Yes, it was not an important position, but when I was passionate （热情的） about it, I could make my life fulfilling.

    All in all, I have to thank you somehow for having the passion to help others because it truly is inspiring to me. So thank you so much, John. My life has changed because your words pointed me in the right direction, Take care!

                                                 Sincerely ,

                                                     Amber

    Climate change has had a number of effects on cities around the world, including rising see levels. And, this has become an especially big problem for coastal cities. City officials must now prepare for higher tides on their coasts. The American city of Miami is one example. Located in South Florida, Miami is home to nearly 3 million people and billions of dollars in land and buildings.

    Miami is one of the cities in America most at risk for rising sea levels. The waterfront is central to Miami's culture and economy. But as the seas rise with climate change .the water will not stay put. Large parts of South Florida are in danger of being under water in the coming years. Across Biscayne Bay, the City of Miami Beach is making improvements - raising streets, adding water pumps and more.

    It is costing the city a lot of money. Local communities will spend 500 million dollars for the improvements. Thankfully, the residents, the folks that are paying the bill for this work, realize that the cost of doing nothing is much greater. A possibility officials are discussing with residents is for city to buy homes in some places where flooding has been a problem. The city would then turn that land into parks of grassland that could hold the water.

    Over time, the city may need to take bigger risks. Miami's future depends largely on how much, and how fast, the oceans rise.

    Caroline Lewis leads the climate activism group, the CLEO Institute. She says cities cannot avoid the need to move inland. But, she says，a well-planned withdrawal (撤退) could include measures to keep people safely in place for as long as possible. And, she says, the world could learn from such a model. In these two Florida cities built on wetlands, there remains a lot of hopefulness.

Yawning（哈欠）sends out certain messages—either “Oh, this movie is boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is so overheated?

    A new study, led by a research team of Princeton University, has indicated（表明）that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.

    The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

    When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.

    The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

    However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

    According to Gallup, this is the first report to show that yawning frequencies(频率) change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.

    Having friends may well keep you healthier and help you deal with stress better. Some studies show that people with close friends have a greater ability to fight disease than people who are alone.

    Place friendship in the first place. Find the time to be with friends even if it means letting the lawn(草坪) go unmowed (未割的) or the dishes unwashed for a while. When you can't get together, use the phone to keep in touch.

    Open up to close friends. Keeping a deep friendship requires a level of “heartfelt” intimacy (亲密).Don't be afraid to express your inner fears and disappointments. Listen to your friends when they have problems， but offer advice only when it's wanted. Help raise friends' self-esteem(自尊) when they are sad about a job loss, or other such events.

    Have different friends for different activities, such as going to the movies， singing in a choir， and joining in a bowling league.

    Don't wait for a friend to ask for helps. When a friend has the flu， offer to go to the store or drive his or her children to their afterschool activities.

    Never take a friendship for granted. Like a good marriage， friendship needs care and patience. Become a joiner. Find a group that matches your interests.

    Talk to strangers. Conversations started in museums, laundry rooms， or bookstores can lead to firm friendship.

    Enroll in an adult education course. A classroom is an ideal place to meet others with similar interests.

    There are a growing number of pet owners who feed their pets on raw foods, which means "uncooked" meat and bones. William Burk, a pet food specialist from the Food and Drug Administration(FDA), believes that feeding raw meat to pets is against its goal of protecting the public from health dangers, and that raw meat and bones do not have all the required nutrition that a pet needs every day.

    Recognizing how popular these foods are, the FDA has provided guidelines for producers of pet foods which contain uncooked meat for dogs, cats and other pets. The guidelines give rules to protect pet owners and pets from dangers about food safety and lack of nutrition.

    Pet owners who feed raw meat and bones to their pets should deal with these products very carefully to protect themselves against possible dangers, says Burk. Just as when you are preparing foods for human beings, use hot water and soap to wash your hands, containers, and surfaces that come into contact with the food. Don't put your hands near your mouth until you have washed them, and don't allow your pet to touch your face right after it has eaten raw meat.

    "If pet owners choose to feed bones to their pets, they should watch their pets carefully when they are eating bones," Burk says, "If a pet eats a big piece of bone that won't pass through its digestive system(消化系统), it is likely to kill the pet."
