Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

    Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is illegal to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

    Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.

    Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

    I am a strong believer that if a child is raised with approval, he will learn to love himself and will be successful in his own way.

    Several weeks ago, I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines. I kept asking him to sit down, telling him that he should concentrate better. He sat but seconds later, as if he didn't even notice he was doing it, he got up again. I was getting frustrated, but then it hit me. I started noticing his answers were much quicker and accurate when he stood up. Could he be more intent while standing up?

    This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet, calm child was a sure way to success. This child would have the discipline to study hard, get good grades and become someone important in life.

    Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality traits, and all you can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to be our kids' best cheerleaders, guiding them and helping them find their way.

    I have stopped asking my son to sit down and concentrate. Obviously, he is concentrating just in his own way and not mine. We need to learn to accept our kids' ways of doing things. Some way may have worked for me but doesn't mean we need to carry it through generations. There is nothing sweeter than being individual and unique. It makes us free and happy and that's just the way I want my kids to live their own life.

    Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags.

    Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

    Among the bag makers' arguments: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.

    The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

    Environmentalists don't dispute（质疑） these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

    Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored（监控）in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.

    “The 'if it bleeds' rule works for mass media,” says Jonah Berger, a scholar at the University of Pennsylvania. “They want your eyeballs and don't care how you're feeling. But when you share a story with your friends, you care a lot more how they react. You don't want them to think of you as a Debbie Downer.”

    Researchers analyzing word-of-mouth communication-e-mails, Web posts and reviews, face-to-face conversations-found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times' website. He and a Penn colleague analyzed the “most e-mailed” list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times' readers and made them want to share this positive feeling with others.

    Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused（激发）one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, “Contagious: Why Things Catch On.”

    When Warren Buffett was asked about the secret to his wealth and success, he said that he read every day—500 pages.

    What do you think would make you happier at work? Perhaps a little more pay might be nice, or maybe some more admiration from fellow colleagues. Are you making the right trade-offs in life? While career achievements can be satisfying, neglecting your family and friends can be harmful in the long-run – in ways you can't even imagine.

    This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

    The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

    Sensors（传感器）record each movement and send it by an ankle transmitter（脚踝发射器）to a smart phone.  Then a "virtual coach" application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

    The socks should be useful to athletes and weekend joggers. "People think running is so easy and of course everybody can do it but not necessarily safely and well, "Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such as golf, or even to help to teach women to walk better in high heels.

    Mr. Vigano said, "People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely. "

    Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around￡120, which will go on sale in March.
