Last night's meteor(流星) shower left many people in Emerald Valley dissatisfied. They gathered in the suburbs of the city with heavy telescopes，expecting to watch the brightly burning meteors passing through the sky. However, what they found was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead.

    “My family was so frustrated，” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing，but it turned out to be a huge disappointment.”

    Astronomers—scientists who study stars and planets—have been complaining about this problem for many years. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

    Besides professional and amateur(业余的) star observers, there is yet a population that suffers even more from light pollution. This population consists of birds，bats, frogs, and snakes etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark­Sky Association, “100 million birds a year throughout North America die in crashes with lighted buildings and towers. ”

    Countless animals injuries and deaths result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful to humans, too. They worry that exposure to light while sleeping can increase people's chances of getting cancer.

    Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona has enforced lighting rules in its city in order to help astronomers with their observations. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

    Airports are dull places where bored passengers kill time eating rubbish food they don't want and buying stuff they'll never need. Right?

    Wrong! Many of today's terminals（航站楼）around the world offer great entertainment, dining and shopping. With so much to offer, you're almost attracted to miss your flight.

    ⒈Changi Airport, Singapore

    It's the only one in the world with its own butterfly garden, and each of the three terminals has its own indoor playground and video game area.

    If you have a long wait you could always watch the latest movies at the free cinema, go to sunflower gardens or take a dip in the rooftop swimming pool.

    ⒉Incheon Airport, Seoul, South Korea

    A five-minute free shuttle bus ride will take you to the SKY72 Golf Club, with three courses and a driving range.

    There are seven gardens inside the terminal, an ice rink, a spa and the Museum of Korean Culture. There is even a casino（赌场）.

    ⒊Dubai Airport, UAE

    It has its own health club with a Jacuzzi, gym and swimming pool, or you can wander in the Zen Garden. The weary can take a rest in a sound-proofed pod with a bed for a while.

    ⒋Hong Kong Airport

    Not only does it have its own IMAX cinema, the airport is home to Green Live AIR, a hi-tech space offering both nine and 18-hole golf simulations（模拟）.

    For kids, there's the Dream Come True Education Park, where they take part in role-playing jobs, or the Aviation Discovery Centre, with themed exhibits and graphics, and the Sky Deck runway viewing platform.

    ⒌Munich Airport, Germany

    Go to the outdoor Visitor's Park to check out the historic aircraft, watch the planes from the viewing hill or browse in the souvenir shop. For kids, there's Kinderland, a fun paradise with a big “adventure plane”, films, games, arts and crafts, and a waiting room for their tired parents to relax in.

    And, of course, since we're in Bavaria there's a beer garden!

    Last month, the president of the Maldives, Mohamed Nasheed, held an underwater meeting. The purpose of the ocean floor conference is to highlight the effects of global warming on his island nation.

    The Maldives, located in the Indian Ocean, is the lowest-lying country on Earth. Melting glaciers and polar ice are causing sea levels to rise, putting the Maldives and other low-lying areas at risk of being swallowed by the sea within the next 100 years.

    What can be done? Scientists and leaders from 190 nations will try to figure that out at the United Nations climate change conference next month. The main goal of the meeting is to come up with a new climate agreement for 2012 and beyond. That is when the existing plan, the Kyoto Protocol will expire. The agreement was created in Kyoto, Japan, in 1997. Since then, it has been ratified(正式批准) by 190 nations. The countries promised to limit the amount of greenhouse gases, such as carbon dioxide, which they produced each year.

    The debate over who should cut greenhouse emissions has been going on for years. The US has been hesitant to reduce emissions unless fast-growing nations such as China and India also reduce their use of fossil fuels. In recent months, China has taken steps to be greener. But India has been unwilling to change. It argues that it is unfair for rich nations to ask poorer countries to cut down on emissions.

    While world leaders work on a plan in Copenhagen, there are many things you can do to help the planet. You can save fuel by walking or biking instead of riding in a car. You can start a recycling program in your community. You can plant trees. Trees absorb carbon dioxide from the air and give off oxygen.

    Good news! Job offered.

    I have just arrived in a country where I don't know the language, where I have no family roots and where I find myself all alone. It may sound frightening. But let me tell you a little secret: it is not.

    When you travel abroad by yourself for whatever reason—exchange program, internship, volunteering, or simply as a tourist—a new and fascinating world will open up for you. A world you would have never been able to see if you had just stayed at home.

    People from a different country are not aliens. They are simply people like you who happened to be born in another region. They have pretty much the same wishes and worries as people from your own country.

    I know that you see a lot of news on TV saying terrible things people do all the time. Your family may have spent a great deal of time telling you not to trust strangers. However, when you travel alone you will realize that people are just as good as you. Everyone is just leading their lives, working, studying and having a good time with their friends. Most people will be happy to help you and get to know you.

    Maybe in the past when you would need months to travel from one place to another, traveling could be expensive. Nowadays, the world is just so connected that it is perfectly possible to find cheap flights, accommodation for all budgets and cheap and quality food.

    You will get lost, but it's fine! I can't even count how many times I didn't know where I was going or how to find the right direction. Everything looks great on Google maps, but sometimes your phone will die or your data will end. Just calm down. Go to a store or stop someone in the street and ask! Or simply walk around and be curious.

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees." We have technologies to train social robots to do things not for us, but with us," said Breazeal.
