Water covers 70% of the Earth, but only 3% of it is clean and suitable for human consumption. Even if you live in an area with enough rainfall, using water requires energy to process, pump, heat, re-pump, and reprocess it.{#blank#}1{#/blank#}

    Save water from your taps.

    Turn the tap off while you are brushing your teeth, shaving, washing your hands, doing dishes, and so on.{#blank#}2{#/blank#} Get wet, and then turn off the water while you soap up. Turn it back on for long enough to wash away the soap.

    Take a timer, clock, or stopwatch into the bathroom with you and challenge yourself to cut down your showering time. You could even play music while in the shower and challenge yourself to cut down the number of songs it takes you.{#blank#}4{#/blank#}

    Use wastewater from the bath, washing machines or dish washing on the garden.

    If possible, connect a pipe to the outlet on your machine to send the water outside onto your garden. When hand-washing dishes, rinse (冲洗) the dishes into a container, and empty the container into your garden.

    {#blank#}5{#/blank#} Either pour it directly into the bowl, or use it to refill the toilet tank when you flush.

A. If you're not sure whether wastewater is suitable for plants, you can use it to flush (冲) your toilet.

B. Not all toilets will be able to flush effectively with a reduced amount of water.

C. Turn the tap off when you shower, too.

D. Replace your clothes washing machine with a high-efficiency washer.

E. Shave outside the shower, or turn off the shower while you shave.

F. Take shorter showers.

G. Fortunately, there are ways to save water for everyone.

    They may be teenagers, but 17-year-old Brittany Bull and 16-year-old Sesam Mngqengqiswa have grand ambitions(雄心) — to launch Africa's first private satellite (卫星) into space. They are part of a team of high school girls from Cape Town, South Africa, who have designed and built equipment for a satellite that will orbit over the earth's poles scanning Africa's surface.

    Once in space, the satellite will collect information on agriculture, and food security within the continent. Using the data/we can try to determine and predict (预测) the problems Africa will be facing in the future”, explains Bull, a student at Pelican Park High School.“Where our food is growing, where we can plant more trees and vegetation and also how we can monitor remote areas,” she says. “We have a lot of forest fires and floods but we don't always get out there in time.'' Information received twice a day will go towards disaster prevention.

    It's part of a project by South Africa's Meta Economic Development Organization (MEDO) working with Morehead State University in the US.

The girls (14 in total) are being trained by satellite engineers from Cape Peninsula University of Technology, in an effort to encourage more African women into STEM (science, technology, engineering, mathematics).

    Scheduled to launch in May 2017, if successful, it will make MEDO the first private company in Africa to build a satellite and send it into orbit.

    Mngqengqiswa comes from a single parent household. Her mother is a domestic worker. By becoming a space engineer or astronaut, the teenager hopes to make her mother proud. “Discovering space and seeing the Earth's atmosphere, it's not something many black Africans have been able to do, or get the opportunity to look at I want to see and experience these things for myself,” says Mngqengqiswa.

    Her team mate Bull agrees, “I want to show to fellow girls that we don't need to sit around or limit ourselves. Any career is possible-even aerospace.”

    Recent summer temperatures in parts of Australia were high enough to melt asphalt. As global warming speeds up the heat and climatic events increase, many plants may be unable to cope. But at least one species of eucalyptus tree can resist extreme heat by continuing to “sweat” when other essential processes stop, a new study finds.

    As plants change sunlight into food, or photosynthesize (光合作用), they absorb carbon dioxide through pores on their leaves. These pores also release water via transpiration(蒸腾), which circulates nutrients through the plant and helps cool it by evaporation(蒸发). But exceptionally high temperatures are known to greatly reduce photosynthesis—and most existing plant models suggest this should also decrease transpiration, leaving trees in danger of fatally overheating. Because it is difficult for scientists to control and vary trees' conditions in their natural environment, little is known about how individual species handle this situation.

    Ecologist John Drake of the S.U.N.Y. College of Environmental Science and Forestry and his colleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large, climate-controlled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia. Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees Celsius higher. The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell, then induced a four-day “extreme” heat wave: They raised the maximum temperatures in half of the pods（three with surrounding temperatures and three of the warmer ones）— to 44 degrees ℃.

    Photosynthesis ground to a near halt in the trees facing the artificial heat wave. But to the researchers' surprise, these trees continued to transpire at close-to-normal levels, effectively cooling themselves and their surroundings. The trees grown in warmer conditions coped just as well as the others, and photosynthesis rates bounced back to normal after the heat wave passed, Drake and his colleagues reported online in Global Change Biology.

    The researchers think the Parramatta red gums were able to effectively sweat — even without photosynthesis — because they are particularly good at tapping into water deep in the soil. But if a heat wave and a severe drought (干旱) were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.

    Other scientists call the finding encouraging. “It's definitely good news,” says Trevor Keenan, an ecologist at Lawrence Berkeley National Laboratory, who was not part of the study. “It would be very interesting to know how this translates to other species,” he adds. Drake hopes to conduct similar experiments with trees common in North America.

    Through your childhood and, let's be honest, most of your adult life, you may have wondered—how do you get to Sesame Street? After 50 years, the answer has finally been revealed.

    New York City's Official Sesame Street

    In the past, there was guessing about the true location of the street, like Harlem or Alphabet City since both neighborhoods resembled Sesame Street in appearance and population makeup. Recently, in honor of the children's television show's 50th anniversary, New York City Mayor Bill de Blasio declared that West 63rd Street between Central Park West and Broadway will now officially be known as Sesame Street, close to the Sesame Workshop office.

    A Year-long Celebration for the 50^th Anniversary

    Since 1969, the children's television show Sesame Street has been a pioneering force in media and education, dealing with issues like racism, loss, poverty and living with a disability. With a mission to help kids everywhere grow smarter, stronger, and kinder, Sesame Street has brought the life-changing benefits of early learning to children across the globe for 50 years. Today, we reach kids in 150 countries and 70 languages and we're celebrating our landmark anniversary with fans and families all year long!

    Events and Activities Throughout 2019

    Fans and families around the world can join their favorite furry friends in celebrating Sesame Street's past, present, and future, with:

    A 50th television season which focuses on the power of possibilities, empowering kids to take safe risks and learn from their mistakes.

    A nationwide road trip where Sesame Street characters and friends host community events in ten cities around the country.

    A research report that will explore an important issue facing kids and families today.

    Celebrity and fan-fueled social media campaigns showcasing favorite Sesame Street memories.

    New corporations across fashion, lifestyle, and themed entertainment for fans of all ages.

    A November star-studded prime-time special, whose contents include new takes on classic scenes and visits from Sesame Street icons.

    Breakfast is not only the most important meal of the day, but also the most neglected. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.

    Breakfast simply means "break the fast". Your body spends at least 6 to 12 hours each night in a fasting state. In the morning your body needs energy for the day's work ahead.

    A good breakfast should provide up to 1/3 of your total calories needs for the day. On average(平均)we eat 400 less calories for breakfast than for dinner. If breakfast doesn't attract you in the morning, try eating a lighter for the breakfast in the morning.

    If you aren't hungry in the morning, start with something small like juice or toast or have a nutritious mid-morning snack alter when you are hungry.

    So, you say you're on a diet. Some people fear eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you eat more. That's because your body is working all day long, in fact, you are probably not.

    Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state it will not be able to burn those extra calories very quickly. If you feed your body healthy snacks and meals through the day, you are less likely to become hungry and fill yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as bread, rice, noodles and cereals(谷物).
