How to Be Confident

    We are all human and have weaknesses. Even if your physical appearance or social skills aren't what you wish they were, that doesn't have to stop you from being confident. {#blank#}1{#/blank#}

    *Make a list of special talents you have, or things you do that are good—morally（道德上） or otherwise. It doesn't have to be a specific skill；it can be an approach or an attitude that you hold through life. {#blank#}2{#/blank#} Are you very patient with people? Do you always see the humorous side of things? Are you always there for your friends?

    {#blank#}3{#/blank#} When you feel strongly about something, speak loudly and clearly and make eye contact with people. People will judge you all the time, and usually they'll misjudge you anyway, so why bother trying to live up to their opinions at all?

    *Take care of yourself. Eat a healthy diet and get enough exercise. Don't abuse your body, don't overload it, and don't deny it any of the things it needs. At the same time, don't obsess(沉迷). {#blank#}4{#/blank#} Those things are only band-aids(权宜之计） and make-up. Confidence comes from within. In order to be confident, you must value yourself and understand that your well-being is important.

    *Improve your posture. {#blank#}5{#/blank#} Don't drop your shoulders. Make sure that your back is straight, your shoulders are square, and your chest sticks out slightly (but stay loose, otherwise you'll appear stubborn （固执的）and nervous). Good posture also helps with deep breathing, which helps with feeling calm and relaxed.

    For years, scientist and others concerned about climate change have been talking about the need for carbon capture and storage(CCS).

    That is the term for removing carbon dioxide from, say, a coal-burning power plant's smokestack and pumping it deep underground to keep it out of the atmosphere, where it would otherwise contribute to global warming.

    However, currently, only one power plant in Canada captures and stores carbon on a commercial scale (and it has been having problems). Among the concerns about storage is that carbon dioxide in gaseous or liquid form that is pumped underground might escape back to the atmosphere. So storage sites would have to be monitored, potentially for decades or centuries.

    But scientists at Lamont-Doherty Earth Observatory at Columbia University and other institutions have come up with a different way to store CO₂ reacts with the rock to form a mineral call calcite(方解石). By turning the gas into stone, scientists can lock it away permanently. Volcanic rocks called basalts(玄武岩) are excellent for his process, because they are rich in calcium, magnesium and iron, which react with CO₂.

    The project called CarbFix started in Iceland, 2012, when the scientists pumped about 250 tons of carbon dioxide, mixed with water, about 1,500 feet down into porous basalt. Early sings were encouraging: The scientists found that about 95 percent of the carbon dioxide was changed into calcite. And even more importantly, they wrote, the change happened relatively quickly—in less than two years.

    “It's beyond all our expectations,” said Edda Aradottir, who manages the project. Rapid change of the CO₂ means that a project would probably have to be monitored for a far shorter time than a more conventional storage site.

    There are still concerns about whether the technology will prove useful in the fight against global warming. For one thing, it would have to be scaled up enormously. For another, a lot of water is needed—25 tons of it for every ton of CO₂—along with the right kind of rock.

    But the researchers say that there is enough porous basaltic rock in Iceland, including in the ocean floors and along the margins of continents. And sitting a storage project in or near the ocean could potentially solve the water problem at the same time, as the researchers say seawater would work just fine.

    Whenever we talk about holidays, my mother teases my sister and me about how we “make out like robbers.” She is referring to the fact that we are half Jewish and half Indian, so we receive gifts on both the festivals of lights: Hanukkah and Diwali. Though my mother teases us, I do not mind getting two sets of gifts!

    Hanukkah is celebrated on the 25^th day of the Jewish month, which is usually sometime in December. On Hanukkah, like most Jewish families, we light a menorah and say a prayer each night. We also say a special prayer on the first night. After that, it is a tradition for my sister and me to do 'hot and cold' for our hidden Hanukkah gifts. When we walk towards the gift, our parents say 'hot' and when we walk further away, they say 'cold'. We each receive one present every night of Hanukkah. Another part I like about this holiday is seeing family members who we do not see often. My aunt usually stays for a few days, and we sometimes visit other relatives.

    Diwali is celebrated on the 13^th day of the dark fortnight of the month of Ashwin (October/November). To celebrate Diwali, my family does a pooja, or prayers, in honor of the goddess Lakshmi. Since she is the goddess of wealth and prosperity, the pooja includes washing silver coins in milk and water. In India, people decorate their houses with lamps, similar to the way you might light up your house for Christmas. My family just places a few candles outside. We also set off firecrackers, which is my favorite part. We often do this activity with friends to add to the excitement.

    Both holidays have different histories and stories. We celebrate them in different ways, yet they both have the same meaning. They both translate into Festival of Lights, and they both mean family and presents for me!

    Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

    Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't expect it to show up in too many driveways. It's expected to cost $279,000.And it won't help if you're stuck in traffic. The car needs a runway.

    Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.

    Mann said Terrafugia was helped by the Federal Aviation Administration's decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

    Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper-a little bird called a honey guide.

    The honey guide does not actually like honey, but it does like the wax in the beehives(蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax(蜂蜡), always falls to the ground, and this is when the honey guide takes its share.

    Scientists do not know why the honey guide likes eating the wax, but it is very distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

    Reality TV show has been charged with making the nation silly, but a study suggests part of the show could be good for children.

    Massey University PhD student Jacinta Hawkins looked at the influence of TV programs on kids' health knowledge, attitudes and behavior. She said programs which showed overweight people on TV is making children say "I don't want to grow up like that'."

    The research was part of Ms Hawkins' paper on how schools improve health. She spoke to 92 children, ages from 7 to 13, from six Auckland primary schools to find out how they received information on nutrition and physical activity. Some said they learnt from TV news programs, but most of them mentioned reality shows such as Fat Chance, Honey We're Killing the Kids and Downsize Me.

    "Earlier studies had looked at the effect junk-food advertising had on children," Ms Hawkins said, "but messages within TV programs had not been explored. Children from the six schools largely recognized program content, rather than advertising, as a source of food and physical activity messages. They are learning habits of eating and exercise from TV programs. "

    The children also recognized that their parents had a role to play in shaping health behavior. Talking about Honey We're Killing the Kids, which shows how people will look if they continue with good habits, children said they developed attitudes from their family's habits. MMs Hawkins said children remembered what they had seen and thought it was the parents' duty to lead by example.
