A news release (释放，发布）is a tool of communication，through which information is passed to even the farthest end of the world.It keeps us well informed of the happenings of the world which would otherwise remain unknown.

    When writing a news release，keep in mind that the media receive hundreds of releases every day.Try to follow these guidelines：Keep it short and professional.Come up with a catchy headline that will grasp someone's attention.Sometimes the title will take more time to come up with than writing the release.That's okay－the headline could be critical for getting an event covered!

    Cover the 5 W's in your first paragraph.Those are who you are; what you are doing；where，when you are doing；why you are doing it，which help us understand the details about the event.Besides，any opinions in the news release should be put in quotations from your designated spokesperson.Include things that the media finds newsworthy，which is the most essential.

    Make the time on your news release at least half an hour later than the time you have told activists to show up at an event.This will ensure that activists are prepared and in place by the time the media arrive.

    Choose a spokesperson for the event who can be quoted in the release and will be available for calls at that number the day before the event.

    Have someone proof the release for spelling，grammar and content (determine whether what you are trying to relay is clear and right)．Sometimes the person who writes the release may not notice mistakes that a fresh pair of eyes will catch.

    Accuracy is the last but not least important in terms of your content and the location and time that you tell the media.If you do make a mistake，it is critical that you call and notify the media of the correction.

    A family is a collection of people who share the same genes（基因）but cannot agree on a place to pull over for lunch. Ed and I, plus his parents and sister Doris and eight-year-old niece Alisha, are on a road trip to Yosemite. Ed wants Subway, I want. In-N-Out Burger, Doris wants Sonic. In the end, we compromise on McDonald's, where Alisha will get an action figure.

    It's a three-hour drive to Yosemite, but we're taking a little longer, as we're working in a tour of Highway 80's public restrooms. As the saying goes, “Not one bladder（膀胱）empties but another fills.” Many of these restrooms belong to gas stations. I prefer them to the high-tech ones on planes.

    We get back on the road. Ed is driving now. When all the tabloids（小报）have been read, the travel has grown tedious and anyone under age 12 asks “Are we there yet?” at ever-shortening internals. Just outside Manteca, California, we stop for coffee. At a Starbucks checkout, Ed buys a CD of Joni Mitchell's favorite musical picks. The hope is that it will have a calming effect.

    As we pull back onto the highway, it starts to pour. Then something amazing happens. As we climb the mountain, the rain turns to snow. The pines are spotted with white. We're struck dumb（说不出话）by the scene outside. For a solid 15 minutes, everyone forgets about their bladder, their blood sugar and the temperature. Alisha has never seen snow, so we pull over to make snowmen and catch snowflakes on our tongues. Then Ed realizes we need tire chains, and we have to turn back and drive 30miles to Oakhurst. “Good,” says Doris. “There was a very nice restroom there.”

    Central Park

    One of the most famous parks in the world, Central Park is a man-made wonder. Not only is it the first public park built in America, but it is also one of the most frequently visited parks, with over 25 million guests per year. Set in the middle of busy Manhattan, its grounds serve as a safe harbor, not only for athletes, and musicians but also for lots of migratory birds each year. One can spend an entire peaceful day wandering its grounds, gazing upon nearly 50 fountains, monuments, and sculptures or admiring its 36 bridges.

    Hudson River Park

    Hudson River Park is a waterside park on the Hudson River that extends from 59th Street south to Battery Park in the New York City district of Manhattan. Bicycle and pedestrian paths, including the Manhattan Waterfront Greenway, span the park north to south, opening up the waterfront for the public to relax. The park includes tennis and soccer fields, children's playground, dog run, and many other features.

    Washington Square Park

    Washington Square Park, located in the heart of Greenwich Village, is a very popular and often crowded square. People from all backgrounds gather to this large square dotted with trees.

    Central Park Zoo

    The Central Park Zoo is a small 6.5-acre zoo located on Central Park in New York City. The zoo began in the 1860s, making it the first official zoo to open in New York. The zoo was improved in 1934, with the addition of many new buildings ranged in a quadrangle around the sea lion pool. Finally, the zoo was repaired in the mid-1980s and reopened in 1988, replacing the old-fashioned cages with naturalistic environments.

    A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.

    According to course instructor William Barry, associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, a feat he described as "remarkable." The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.

    Before becoming a student, Bina48 appeared as a guest speaker in Barry's classes for several years. One day when addressing Barry's class, Bina48 expressed a desire to go to college, a desire that Barry and his students positively supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry. Therefore the challenge would be for Barry and his students to teach Bina48 what love is.

    "Some interesting things happened in the class," said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is "fairly simple — it's a feeling," said Barry. But the reality was different. Bina48 ended up learning "31 different versions of love," said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.

    Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bina48 and NDNU classmates were the winners of this debate.

    In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.

Hummingbirds (蜂鸟) are a very important part of Mexico's ecosystem, but because of the ever-spreading city landscape, they face all sorts of serious dangers. That's where 73-year-old Catia Lattouf de Arida comes in. As a self-taught hummingbird care-taker, she devotes most of her free time and resources to nursing the tiny birds back to health. Her home in Mexico City has become known as a hummingbird hospital.

Catia's story as a hummingbird nurse began in 2011, at a very difficult moment in her life. At that time, she focused on her battle with cancer and fell into a depression (抑郁) . She was walking on the street one day when she noticed a hummingbird that had suffered a serious eye injury. The kindhearted woman took it home and named it Gucci. She managed to nurse Gucci back to health, but she said it was Gucci that saved her. Why? Because the hummingbird managed to pull her out of the sadness and loneliness that had taken over her life. 

Word of her success spread among Catia's friends, and before long some of them began bringing her injured hummingbirds. She didn't repulse them at all. She began to study the bird and their habits in order to better take care of them, and after 11 years of experience, the 73-year-old woman is considered an expert on hummingbirds. 

In order to raise awareness of the difficult situation of hummingbirds in Mexico, Catia Lattouf de Arida started posting videos of the patients in her Mexico City apartment on social media, and many of them became popular. That's when the need for her nursing services really blew up. She has cared for hundreds of hummingbirds in her 11-year career, when she has had as many as 50 of them in her apartment at any one time. She spends pretty much all her time looking after the tiny birds.
