On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, “You're nervous and that's okay. Everyone is afraid of high school. ”I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends.

    On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be？ I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it！The schoolmates seemed to regard me as a fool, and they were probably right.

    Despite my fears, after the first week I finally had my schedule figured out.

    With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad.  It was actually much better than middle school and much more challenging.

    Since then, I've been elected vice president of my class, which wasn't much of a victory since only three people ran for the four positions.

    It is normal to be scared about a new school. Take a deep breath and relax. High school is something that any student can overcome. Make sure you participate in some out-of-class activities because you'll find it easier to make friends. Try to do your best, even if it isn't straight A's.

    Most important of all, be who you are , whether you're a “fool”, an athlete, or a lower grader. Don't try to pretend to be someone you're not. Now you know the true secrets of high school.

    The advice offered from any other 82-year-olds might have made young people yawn and roll their eyes. But when former South African president Nelson Mandela advised two dozen local youth leaders in Los Angeles to take education seriously, his audience was listening.

    The famed old man said to the young people that if they expected to improve the lives of others in the future, they must work at improving their own lives now. "Education is one of the most important weapons you have,” Mandela advised. “It will place you in a far better position to serve yourself and your community.”

“The point is, he was young once and rebellious(叛逆的)once and he kept his dream alive, just as you each have dreams,” explained South Africa's ambassador to the United States, Sheila Sisulu, as she introduced Mandela to the young crowd.

    Asked for specific advice about changing society by 21-year-old Ahmed Younis, Mandela suggested that somehow helping arouse more American interest in foreign affairs might be a start.

There is an impression that Americans, in general, have not followed international developments properly, Mandela said. “I'm not making that statement myself, but there are serious political analysts who say Americans are not well informed as to what has happened in the world.”

22-year-old Omari Trice said Mandela left him full of enthusiasm. “ He's a person who set the tone for an entire nation, said Trice. “You come away feeling you need to be a superman in order to get things done.”

    Several years ago, Masaru Ibuka, chairman of Sony, was at a company planning a meeting. Suddenly he had a brilliant idea. He stopped the meeting and asked everyone present what would happen if Sony removed the recording function and speaker and sold headphones with a tape player instead. Almost everyone thought he was crazy. Still, Ibuka kept thinking about his idea and worked at improving it. The result, of course, turned out to be the wildly successful Sony Walkman.

    Good ideas often start with a seemingly silly question. Bill Bowerman was making breakfast one day. As he stood there making waffles (华夫饼干)for his son, he wondered what would happen if he poured rubber into his waffle iron. Later, he tried it and the result looked something like the bottom of most sports shoes we see today. Still, when he took this idea to several existing shoe companies, he was laughed at. In fact, every single company turned him down. Though rather discouraged, Bowerman insisted and went on to form his own company, making NIKE athletic shoes.

    Sometimes good ideas grow out of frustration .When Fred Smith was a student at Yale University, he had some paperwork that he needed to have delivered across the country the next day. Smith was amazed to find out that overnight delivery was impossible. He sat for a long while, lost in thought. Why couldn't there be a reliable overnight mail delivery service? He decided to design one. Smith did just that and turned his design into a class project.  His business professor gave him only a C for his efforts. However, Smith was not through. He improved the idea in that class project and finally turned it into one of the first and most successful overnight mail service in the world — FedEx.

    We know that each of these ideas led to a very successful product or service that has changed the way many of us live. The best questions are usually open-ended and are often silly, Children aren't afraid to ask such questions, but adults frequently are. Think how different the world might be if people never asked "silly" questions!

    Times are a little tough at our house right now. Neither of us makes a lot of money, but years of experience have taught us how to walk between the raindrops and make it from one month to the next with a fair amount of grace. I cook a lot at home, more when we're facing difficult times. When I know that I have to keep us fed on not much money, I fall back on my grandmother's recipes. She taught me to cook.

    When I was a kid, my twin brother and I spent long summer weeks and Christmas vacations with my mother's parents in the mountains of North Carolina. Rather than go hunting with my grandfather on mornings, I found myself more and more in the kitchen with my grandmother, watching her making a lemon cheese pie with her soft hands.

    My great-grandmother died when my grandmother was 11 years old. As the eldest daughter, she was expected to take on all of the housework while attending school. Throughout the Great Depression, she learned how to make a little food go a long way. Vegetables were cheap, so she cooked a lot of them, mostly only using small amounts of meat for seasoning. Roast beef was a twice-a-month luxury, but there was nothing she couldn't do with a chicken, every part of it. Nothing went to waste.

    Now I understand that her food was sacred (神圣的). I feel connected to my grandmother and to hundreds of years of family when I'm in my kitchen making country food. In the delicious smells is a long tale of victory over hard times, of conquering starvation of not just surviving, but finding joy and pleasure in every meal of every day.

From grandmother I learned to take real satisfaction in feeding people. My grandmother would beam with pleasure over a heavily laden table and say: "Do you know what this would cost at the restaurant?" I never knew what restaurant in particular she had in mind, but I knew that the question was totally not fair, because no restaurant anywhere can cook like a grandmother. But now, thanks to her guidance and years of practice, I can.

    Photos of the moon are beautiful if taken well, but it can be very hard to get a picture of the moon that doesn't look blurry! In order to take a perfect picture of the moon, apart from a high­quality camera, the associated equipment and the skills to set up your camera, you also need to pick a proper time and a good place.

    Choose your favorite moon phase. The moon can be photographed in any phase except the new moon, which is not visible to Earth. The first quarter, half, and third quarter phases provide high contrast that allows you to see the craters(坑) in greater detail, while the full moon is a dramatic choice for a skyscraper. What phase you choose is up to your personal preference, but it's best to have a phase chosen before going out to photograph the moon.

    Learn when the moon rises and sets. When the moon sets or rises, it is closer to the horizon, making it appear larger and closer. This makes it much easier to photograph! Check an almanac(年历) or a weather app for moon rising and setting times in your area.

    Pick a clear night. Clouds, fog, and air pollution will blur your photographs. Check a weather app or watch the weather forecast before leaving for your session and while photographing. A clear night with low smog content and no rain is best for moon photography.

    Choose a location away from direct light sources. The moon appears bright because it reflects the light of the sun, and additional light from streetlights, homes, and cars can make the moon appear duller and blurrier in pictures. It is fine if there is light in the distance, but be sure that you are not photographing close to another light source.
