It may not be as easy as you think to build a foundation for your child of family values. Often we believe that our child will pick up on our values if they live in the same home. While they may pick up many of our values, parents need to remember they are not the only influence in their child's life. These outside values often compete with family values for your child's attention. If we do not make a conscious effort to instill our values into our children, they may not get instilled at all.

    I wish I had learned that lesson a little earlier. I thought if I lived my values for my children they would pick them up and make their own. Sometimes this happened and sometimes it didn't. I often see twenty-something “kids” who have no faith in many of the values of their family in favor of the values of their friends. Children will often pick up the negative you show quicker than the positive, so the positive things need extra focus to set them.

    Some of the influences your children face every day include their church, their school, their friends, any clubs or sporting groups they are part of and more. Kids spend many hours a day at school and with their friends. Sometimes in the business of life, we suppose our children will obtain that foundation we want for them.

    Instilling a foundation of family values to sustain(维持) your child requires more than living it in front of them. That is important, but building up your child with this important foundation must become intentional.

    That means we plan times to gather as a family. We plan activities together that show the values we want to pass on. We talk about our values; we live our values; we discuss the values of others and how they differ from ours; we constantly look for opportunities and make our own opportunities to share these values in word or deed with our children.

    Family values give our children a foundation to build upon. It helps them know they are loved and gives them a sense of belongings. Upon this sure foundation, they can spread their wings and grow to become parents who share these same values with their own children.

    At times my mom has been uncomfortable seeing these qualities in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

    But despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of me going away, she was supportive and excited for me.

    One big thing I realized during my senior year, as my mom granted me more freedom, was that she actually believes in me and trusts me. That means a lot. Most of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards; getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's.

    I know that her high standards have helped me stay focused on what's important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

    If humans were truly at home under the light of the moon and stars，we would go in darkness happily，the midnight world as visible to us as it is to the vast number of nocturnal(夜间活动的) species on this planet. Instead，we are diurnal creatures, with eyes adapted to living in the sun's light. This is a basic evolutionary fact, even though most of us don't think of ourselves as diurnal beings. Yet it's the only way to explain what we've done to the night: We've engineered it to  receive us by filling it with light.

    The benefits of this kind of engineering come with consequences 一 called light pollution 一 whose effects scientists are only now beginning to study. Light pollution is largely the result of bad  lighting design，which allows artificial light to shine outward and upward into the sky. III-designed lighting washes out the darkness of night and completely changes the light levels 一 and light  rhythms — to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect or life is affected .

    In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(霾) that mirrors our fear of the dark. We've grown so used to this orange haze that the original glory of an unlit nigh, - dark enough for the planet Venus to throw shadow on Earth, is wholly beyond our experience, beyond memory almost.

    We^'ve lit up the night as if it were an unoccupied country, when nothing could be further form the truth. Among mammals alone, the number of nocturnal species is astonishing, Light is a powerful biological force, and on many species it acts as a magnet(磁铁). The effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms. Migrating at night, birds tend to collide with brightly lit tall buildings.

    Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times righter than normal, throwing nearly every aspect of their behavior out of joint including most other creatures ,we do need darkness .Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.

    Living in a glare of our making,we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night .In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy arching overhead.

    ⒈Siem Reap, Cambodia

    Siem Reap is a fast-growing city with plenty of new hotels, restaurants and nightclubs. But many people are here not because of the city itself, but for the things nearby: amazingly well-preserved ancient temples. Even if you have the worst jet lag (时差反应) ever, drag yourself out of bed to be at Angkor Archaeological Park when it opens. The sunrise over Angkor Wat is worth losing sleepover.

    ⒉Rome, Italy

    Rome is a city of contrasts (差异) — where else on earth could be home to both the Vatican and La Dolce Vita? Rome is unique in that it offers a great combination of different art, culture and food. If your preference is for sports, then Rome also has a lot to offer. In terms of music and live entertainment, a lot of the most famous Italian and international artists also tend to include Rome on European and world tours.

    ⒊New York, America

    The first time you go to New York, go ahead and be a sightseer- everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighborhood and go deep. You will find hole-in-the-wall bars, strange shops...Exploring the non-touristy side of New York is an extremely rewarding experience for a traveler.

    ⒋Istanbul, Turkey

    Europe and Asia meet in Istanbul. Throughout this energetic city, you will find centuries-old churches and markets happily coexisting (共存) with modem restaurants, galleries and nightclubs. Though no longer a capital, Istanbul is the heart of the Republic of Turkey and the financial center with a large population.

    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."

A living robot has been created out of frog skin cells. Xenobots, named after the frog species Xenopus laevis that the cells come from, were first described last year. Now the team behind the robots has improved their design and demonstrated new capabilities.

To create the xenobots, Michael Levin at Tufts University in Massachusetts and his colleagues obtained tissue from 24-hour-old frog embryos after very small physical operation. Where the previous version relied on the contraction of heart muscle cells to move them forward by pushing off surfaces, these new xenobots swim around faster. They also live between three and seven days longer than their previous generation, which only lasted about seven days, and have the ability to sense their surroundings to some extent, turning red when exposed to blue light.

"The fundamental finding here is that when you free skin cells from their normal context, and you give them a chance to build other things than what they normally build," says Levin. "To me, one of the most exciting things here is that they are plastic. This idea that even normal cells, not genetically modified, are in fact capable of building something completely different."

Because they are created from cells, the xenobots eventually break apart and are totally biodegradable, says team member Douglas Blackiston, also at Tufts University. He therefore hopes that they can be used for biomedical and environmental applications.

Previous attempts at creating living robots, such as a wirelessly controlled cockroach, have involved dealing with live animals, raising ethical concerns. Xenobots differ from these because they are made entirely of living cells. "The approach here is maybe ethically the least problematic because everything starts with cells. They have no neurons, so it's not an animal," says Auke ljspeert at the Swiss Federal Institute of Technology at Lausanne, who wasn't involved in the research. "It's really cells, so I find it maybe the cleanest way."
