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.

    Under new rules posted by the Civil Aviation (航空) administration of China on Friday, pilots will have to pass a “level four” test of Mandarin Chinese, China's official language. Those who speak with an accent that “often impedes” comprehension will not pass. These rules take effect in January 2016.

    China's 56 ethnic groups speak more than 80 languages and dialects. Even native Mandarin speakers can have trouble communicating with each other depending on the strength of their accents, which can be mutually unintelligible (难理解的).

    One flight trainer illustrated the scope for linguistic confusion, especially when common English aviation terms are used. Asked if there is a problem on board, a Chinese pilot might answer in the negative with the words mei you, or “there isn't.” But someone speaking with a heavy Sichuan accent would pronounce mei you as “May day” — unconsciously parroting the universally recognized distress call (遇难信号).

    Like their international counterparts (对应物), Chinese aviators have developed codes to avoid confusion resulting from homonyms (同音异义字) or near-homonyms. They use the terms yao for one and guai for seven, which are otherwise pronounced yi and qi respectively and easily confused.

    The new rule could affect all pilots, who must renew their license every six years, and adds to a growing list of burdens for the profession.

    Getting less sleep has become a bad habit for most American kids. According to a new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

    How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal. But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

    “More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

    Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.

    Eye Health Care

    When Jenny Benson was eight, her mother took her to soccer practice for the first time.

    "She's never played soccer before," Mrs. Benson told the coach." I'm not sure how she'll do."

    Jenny ran onto the field and joined the other players. Over the next hour, Mrs. Benson and the coach watched as Jenny out­ran many of the more experienced players.

    "I knew then that soccer would be Jenny's sport." Mrs. Benson recalls. And she was right.

    It may have helped that Jenny had spent much of her time trying to keep up with her three brothers." I wanted to be just like them," Jenny says." My family has inspired me for my entire life."

    Jenny has retired from the United States women's national soccer team. She started out on her professional career in the Philadelphia Charge, a team in the Women's United Soccer Association (WUSA)．Later on, she joined FC Energy Voronezh, and then New Jersey Wildcats.

    When the WUSA was being formed, league officials watched many college soccer games, looking for players good enough to join the league. They were very interested in Jenny, who played for the University of Nebraska.

    "Throughout that college season, I knew I was being watched," Jenny says, "I knew I couldn't be perfect, so I just tried to be very consistent and have fun."

    As a professional, Jenny relied on her focused but fun­loving attitude. "In a game, I try never to put too much pressure on myself. The more I concentrate on having fun, the better I play." She says. "I have good and bad days, just like everyone else, but I know the sun will always come up after a bad day. So all I have to do is to adjust myself, either to the change of my inner feelings or to the change of circumstances. That helps me get through anything."

Becoming Bears (Kindergarten-2 grade)

    By becoming baby bears, children learn from their "parent" to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation(冬眠). After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves. (1.5-2 hours)

Whose Clues? (3-5 grade)

    Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognize their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learned, kids will choose one species and tell how they survive in their living places. (3-4 hours)

Winged Wonders (3-5 grade)

    Birds add color and sound to our world and play an important ecological (生态的) role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands-on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3-4 hours)

Exploring Your Watershed (6-8 grade)

    We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see first-hand some of the challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem.

● Each program is taught for a class with at least 10 students.
