A new American weather satellite could save more lives by better predicting extreme weather conditions. It will be in orbit(轨道）some 36,000 kilometers above Earth's surface. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.

    NOAA officials are calling the new satellite GOES-R. That is short for a much longer name—the Geostationary Operational Environmental Satellite-R Series. NOAA said GOES-R could improve the nation's ability to observe weather conditions and make weather predictions. It said the satellite's operation would lead to more exact and timely weather forecasts watches and warnings.

    The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year."

    "The next generation of weather satellites is finally here." said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most complicated Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more detail than any other NOAA satellite currently in operation. She believes this will make the United States an even stronger, more “Weather-Ready" nation.

    A NOAA statement said the greater detail will help improve the agency's study of ocean storms, as well as “the prediction and warnings of severe weather. "In addition, GOES-R will be able to provide improved rainfall estimates (预计), which will lead to more timely and detailed flood warning. The statement also said that GOES-R will give better estimates of wind strength, as well as better measurement of fog, ice or lightning strikes.

    Craig Fugate serves as administrator of the Federal Emergency Management Agency. He says that the GOES-R satellite will improve the ability of people and organizations across America to prepare for, and react to, weather-related disasters.

    "How are you?" is a nice question. It's a friendly way that people in the United States greet each other. But "How are you?" is also a very unusual question. It's a question that often doesn't need an answer. The person who asks "How are you?" hopes to hear the answer "Fine", even if the person's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine" isn't really an answer. They are simply other ways of saying "Hello" or "Hi".

    Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?" the other person might think, "No, I disagree. I think you're wrong…" But it isn't very polite to disagree so strongly, so the other person might say "I'm not sure." It's a nicer way to say that you don't agree with someone.

    People also don't say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says "I have to go now." Often, the person who wants to hang up gives an excuse: "Someone's at the door." "Something is burning on the stove." The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

    Whether they are greeting each other, talking about an idea, or finishing a talk, people don't say exactly what they are thinking. It's an important way that people try to be nice to each other, and it's part of the game of language.

    I love charity(慈善) shops and so do lots of other people in Britain because you find quite a few of them on every high street. The charity shop is a British institution, selling everything from clothes to electric goods, all at very good prices. You can get things you won't find in the shops anymore. The thing I like best about them is that your money is going to a good cause and not into the pockets of profit-driven companies, and you are not damaging the planet, but finding a new home for unwanted goods.

    The first charity shop was opened in 1947 by Oxfam. The famous charity's appeal to aid postwar Greece had been so successful it had been flooded with donations(捐赠物). They decided to set up a shop to sell some of these donations to raise money for that appeal. Now there are over 7,000 charity shops in the UK. My favourite charity shop in my hometown is the Red Cross shop, where I always find children's books, all 10 or 20 pence each.

    Most of the people working in the charity shops are volunteers, although there is often a manager who gets paid. Over 90% of the goods in the charity shops are donated by the public. Every morning you see bags of unwanted items outside the front of shops, although they don't encourage this, rather ask people to bring things in when the shop is open.

    The shops have very low running costs: all profits go to charity work. Charity shops raise more than ￡110 million a year, funding(资助) medical research, overseas aid, supporting sick and poor children, homeless and disabled people, and much more. What better place to spend your money? You get something special for a very good price and a good moral sense. You provide funds to a good cause and tread lightly on the environment.

    Have you ever had your hand held during a dental procedure you feel uneasy about? What about a dental office that mimics（模仿） the spirit of Disneyland? If you're looking for a dental office that provides the best care and the best environment, you're looking for Dr. Licking's office in Sunnyvale.

    Office manager Judy, who has worked with Dr. Licking for 38 years, speaks highly of his kindness. She believes that the office is “the Disneyland of dentistry”. Everyone from children to their grandparents loves the environment and care they receive from this welcoming office.

    Dr. Licking is known as the best dental care provider for anyone who fears facing appointments with the dental office. The staff goes out of their way to make patients feel comfortable and at ease. Dr. Licking and Judy set the standard with their saying, “when someone comes to your home, you stand up and welcome them, like an old family friend.”

    Dr. Licking's office has all. They recently relocated to put the new equipment into their practice. The office is equipped with an intra-oral video camera, and as a patient you can get pictures of your teeth as you're walking out the door.

    Setting himself apart from other dentists, Dr. Licking continues his education beyond what is required. For this reason, he is one of few dentists in the country who offers ozone treatment. Ozone can naturally stop decay (蛀蚀) in its tracks. For more information on this new technology, visit their website at www.drjohnlicking.com.

    Dr. Licking's office is Diamond Certified, an honor given only to companies with the higher quality after extensive and continual research. Dr. Licking's office extends an invitation to you to meet their gentle staff and offers you a free office visit, including x-rays and an exam.

    The office holds extended hours ranging from 7 a. m. to 8 p, m., Monday through Thursday. Don't worry if you have an emergency. Dr. Licking's office responds to all emergencies and urgent calls.

    A unique experience awaits you at the Centre for Alternative Technology on the edge of the beautiful Snowdonia National Park.

    Over thirty years ago a group of people decided to try out alternative technologies. They chose a remote empty place, where rock used to be dug from the ground, as their base. Here experiments offering solutions to the world's energy problems were carried out, and nowadays many of these ideas have become common practice. You can experience all these for yourself in just one day with us, and then take away what you have learned and put it into practice at home. Be assured it will help you save on your household energy costs!

    Your visit to us begins with a ride up a steep 60-metre hillside on a railway which is worked by using the weight of water. At the top of the mountain you will enjoy beautiful views to the distant coastline. Then interactive displays show the power of wind, water and sun, while showing you what can be done in an ordinary household to reduce your influence on the planet.

    There was no soil when the project was started, so we created our organic gardens using our own home-made soil. You can enjoy woodland walks or even notice spring flowers growing on the roofs of environmentally-friendly buildings.

    In 2006 we opened our new eco-adventure playground for children, and we also run workshops where they can make models and become inventors of the future by putting wind, water or solar power into their own designs.

    The Centre for Alternative Technology is open all year round and has good rail, road and cycle links. In fact we offer a 50% reduction on the admission price if you arrive by bicycle. There is wheelchair access for disabled visitors—telephone us in advance if you would like assistance.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
