“You're leaving again?” asked my daughter as she saw me packing my carry-on.

More than her words, it was her face that pierced (刺穿) my heart —I could see how crestfallen she was.

    “It's only for two nights, “I explained.

    But that didn't matter to her. It was just one more trip after barely being home for five days. I decided in that moment to travel less whenever possible and I managed to avoid flying altogether for most of the summer. As a result, it was a summer full of discoveries. I realized that my kids really were proud of me. In their time away from me they had learned lessons I couldn't have imagined.

    Recently I began traveling a lot again. But this time it was different, mainly due to the fact that I had seen firsthand that my children value strong female role models. They realize that hard work pays off. Being away from them even for a day at a time in many ways had done them a lot of good.

In particular, being a working mom is teaching my daughter how important it is to be independent and that you can follow your dreams. In many ways, her idea of a professional woman is much more realistic than what I imagined when I was her age. I think that even at nine years old she already knows that for all the success you might achieve, there is a price to pay, whether it's long hours, spending time away from those you love, or simply not having the energy to have fun at times. I know the wishes I would devote all of my time to her, but honestly, even if I didn't work I would rather she learned not to depend on me for everything, She needs to realize that she can fly on her own — and that isn't possible if I am hovering over her every single second of the day .

    I have also realized that having a career sets a good example for my son. He is not afraid of a strong woman, and has a great respect for them. When he's older, this will help him build healthier relationship.

    Therefore, for all the working moms out there who work long hours, remember to value the positive lessons you might be teaching your kids.

    In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that ________________________ One day, this approach threw me into embarrassment

    In Mrs. Totten's eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals (小数).

    Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions.

    Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had appeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end.

    Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations.

    What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class，I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn't function.

When Mrs. Totten reached my desk，she asked what answer I'd got for problem No. 14. “I…I didn't get anything,” I answered，and my face felt warm.

    “Correct,” she said.

    It turned out that the correct answer was zero.

What did I learn that day? First, always do all your homework. Second, in real life it isn't always what you say but how you say it that matters. Third，I would never make it as a mathematician.

    If I could choose one school day that taught me the most, it would be that one.

    We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It's called wireless charging and this trend is just starting.

    Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they're placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won't need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.

    Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.

    It's a safe bet that a robot made your car and made your computer. Pretty soon, they could be making your bed and breakfast too.

     Increasingly, engineers are saying that robots are going to move out of research departments and into your home. Companies including General Electric are working on designs for small robots. Products like the Roomba, a robot that can clean floors, are flying off the shelves.

     What's behind this new robot revolution? It's partly a matter of technology. Devices that can recognize and respond to a human voice have been developed. There are now a few different ways for robots to move around. They can walk, crawl or ride on wheels. Robots are being made smaller and smaller. They are also becoming more and more able.

     A bigger part of the story is on the demand side. From the day the television remote control was invented, people around the world have searched for new ways to be lazy. Take into consideration that more and more people can afford robots, and the time seems ripe to introduce robots to the ordinary family.

     To be sure, robots that walk on two legs and talk like people are still a long way off. However, robots that do basic housework such as cleaning or gardening are sure to come out soon. One thing is certain—when these robots do come into our homes, it will change things forever.

    Food festivals are a common occurrence in the UK and take place in all sorts of places and at all sorts of times. Whatever your taste, there's a food festival to match -no matter how specialized.

    Meatopia

    This three-day, London-based festival takes place at the end of August and is a meat lover's paradise. In addition to a range of meat products, from burgers to steaks, attendees can listen to live music, watch butchery shows, and attend informal meat-based workshops.

    Vegfest

    If you prefer a festival that will help you meet your five a day, then Vegfest fest is for you. This vegan-friendly event takes place several times a year. Here you can enjoy a wide selection of freshly prepared vegetables, learn cooking tips and hear talks on nutrition to help you make the most of your plant-based search.

    The Marmalade Festival

    Held in Cumbria, this festival has been running for 13 years. It includes a competition to find the best homemade marmalade. There are thousands of entries from over 30 different countries across the globe.

    The Ginger (姜) and spice Festival

    The Ginger and spice Festival, held in Market Drayton, celebrates its town's historic connection to Robert Clive, who returned from India with ginger. Because of this, they specialize in baking gingerbread, but also sell a range of spices from mild to hot.

    The National Honey show

    It started in 1921 and is the largest event of its kind. This three-day event attracts over 2000 participants to their traditional competition and offers lectures and workshops on beekeeping and, of course, that syrupy golden honey.

    While people's tastes are different from each other, the UK has something to offer most people. From large-scale festivities, to the smaller gatherings, one thing is certain: people are passionate about their food. And while some of the products on offer might be strange to someone, when food is given that much attention, it's unlikely to leave a bad taste in anyone's mouth.

    A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors.

    The newly formed Wild Network—a collaboration of nearly 400 organizations—is attempting to attract youngsters away from television and computer screens to fields, woods and parks. Members of the network include the National Trust, RSPB, Play England and the NHS. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being.

    A documentary film, Project Wild Thing, will forecast the launch at more than 50 cinemas across the UK from Friday. It looks at the increasing link between children and nature.

    Andy Simpson, chairman of the Wild Network, said, "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is decreasing, roaming (漫步) ranges have fallen largely, activity levels are declining and the ability to identify common species has been lost."

    Suggestions on how to get more time in nature include collecting conkers (七叶树果), camping, snail racing, and observing autumn colour on trees.

    From January, the network will aim to make suggestions on how the government can do more to get children muddy and bright-eyed.

    This is not the first time the message of less screen time, more play has been brought up. Children in the 1980s were requested to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off the TV set and go to do something less boring instead".
