A long-term American study shows the importance of early education for poor children. The study is known as the Abecedarian Project. It involved more than one-hundred young children from poor families in North Carolina.

    Half of the children attended an all-day program at a high-quality child-care center. The center offered educational, health and social programs. Children took part in games and activities to increase their thinking and language skills and social and emotional development. The program also included health foods for the children.

    The children attended the program from when they were a few weeks old until the age of five years. The other group of children did not attend the child-care center. After the age of five, both groups attended public school.

    Researchers compared the two groups of children. When they were babies, both groups had similar results in tests for mental and physical skills. However, from the age of eighteen months, the children in the educational child-care program did much better in tests.

    The researchers tested the children again when they were twelve and fifteen years old. The tests found that the children who had been in the child-care center continued to have higher average test results. These children did much better on tests of reading and mathematics.

    A few years ago, organizers of the Abecedarian Project tested the students again. At the time, each student was twenty-one years old. They were tested for thinking and educational ability, employment, parenting and social skills. The researchers found that the young adults who had the early education still did better in reading and mathematics tests. They were more than two times as likely to be attending college or to have completed college. In addition, the children who received early education were older on average, when their first child was born.

    The study offers more evidence that learning during the first months and years of life is important for all later development.

    The researchers of the Abecedarian Project believe their study shows a need for lawmakers to spend money on public early education. They believe these kinds of programs could reduce the number of children who do not complete school and are unemployed.

    Some materials are obtained from natural resources that are changed by chemical processes in a laboratory. The resulting artificial materials are synthetic, or human-made.

    Plastic is a synthetic substance, obtained from petroleum, a fossil fuel. The molecules（分子）in petroleum are split and then linked into chains. Plastic is an example of a polymer, a material made of repeating patterns of atoms linked together. Most polymers are synthetic. They are made by polymerization, the process of chemically linking many smaller molecules to form a larger molecule that has different physical features. Some polymers, such as proteins, occur naturally.

    Plastic is a key component of many products. When heated into an almost-liquid form, plastic can be made into fibers, sheets, or molds（模具）. It can be mixed with other elements to remain flexible, or it can harden into a solid. Plastic fibers can be made into clothing or carpeting. Sheets of plastic can be made into plates. Molded plastic can be sued for protective helmets or car bumpers.

    Most plastics can be reheated and remolded repeatedly. This feature makes plastic very easy to use. Polymers can be pulled into fine strings or molded into almost any kind of shape. For example, tubes of plastic can be shaped into bottles by different processes. One such process is extrusion blow-molding. Most plastics are also resistant to many chemicals that might harm other materials. This quality is the reason that so many cleaning liquids are packaged in plastic bottles.

    Plastics are good insulators that can stop electricity or heat to pass through. Look around your kitchen, and observe where plastics are used. Pot handles are sometimes made of plastic, as are cooking tools, toaster controls, and microwave cookware. Food-storage wraps and containers may be made of plastic. Take a walk outdoors, and note all the plastic items you see. Gardening tools, such as watering cans and sprayers, are often made of plastic. Swings and slides made of plastic do not become as hot as metal, so they are safer for play. Because plastics can be heated, remolded, and made into something else, they can be recycled and reused.

    Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.

    But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.

    Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.

    Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    My daughter Kelly is a cautious person. She needs to warm up to situations, and is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, "Girls rule, boys drool." But when that comfort zone is not around her, she is shy and nervous.

    This has been challenging for me at times. "Shy" is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids' triathlon(三项全能).

    On Saturday, with a thunderstorm coming soon and my son's birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

    And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

    I can honestly say that I never felt so proud of someone in my entire life. It wasn't because she did a sport or anything like that. It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before.

    All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

    Shine on, sweet baby.

    If you plan on bringing a moving van or truck it will not fit under the overpasses(天桥) on Soldiers Field Road and Memorial Drive. Plan your route in advance to avoid a risky and costly problem.

    Parking arrangements for trucks and vans must be made in advance as well. Visit your property page for information about parking your car.

    Furniture and Lighting

    Most HUH units have no furniture-the unit is empty except for a stove and a refrigerator. You need to bring, buy, or rent a bed, other furniture, and household items. In many HUH units, rooms do not have overhead lights, so you also may need table or floor lamps.

    If you want to stock up on groceries and some household items as soon as you arrive, please find information about "Grocery Shopping" by clicking the drop-down menu.
