As self-driving cars come closer to being common on American roads, much of the rhetoric（说辞）promoting them has to do with safety. About 40,000 people die on U.S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous（自动的）vehicles aren't car companies looking to improve the safety of their existing products. Huge support for itself-driving technologies is coming from Silicon Valley giants like Google and Apple.

    Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technologically push. In this case, it's clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive（动机）to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data—and often money—to tech companies.

    At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving – as has happened in almost every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an automobile in which continuous cellphone use no longer poses a threat to anyone.

    In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it's around four hours a day for the average adult in the U.S. However, that rapid growth is likely to slow down as people run out of time that's available for them up to use their devices. Unless, of course, there's a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizeable opportunity for increased cellphone use.

    Sop as the public conversation around autonomous cars highlights the safety advantages, don't forget the tech industry's powerful desire for more profits, which goes well beyond simply saving us from ourselves.

    Having a learning disability doesn't mean you can't learn, but you'll need some help and need to work extra hard. If you have a learning disability such as dyslexia or dyscalculia, remember that you are not slow or stupid.

    Learning disabilities can be genetic. That means they can be passed down in families through the genes. But kids today have an advantage over their parents. Learning experts now know a lot more about the brain and how learning works, and it's easier for kids to get the help they need.

    Dyslexia is a learning disability that means a kid has a lot of trouble reading and writing. Kids who have trouble with math may have dyscalculia. Other kids may have language disorders, meaning they have trouble understanding language and understanding what they read.

    It can be confusing, though. What qualifies as “trouble" enough to be diagnosed as a learning disability? Reading, doing math, and writing letters may be tough for lots of kids at first. But when those troubles don't fade away and it's really difficult to make any progress, it's possible that the kid has a learning disability.

    Finding out you have a learning disability can be upsetting. You might feel different from everyone else. But the truth is that learning disabilities are pretty common. And if your learning specialist or psychologist has figured out which one you're facing, you're on the right track. Now, you can start getting the help you need to do better in school.

    But for this special help to really work, you'll need to practice the new skills you're learning. It may take a lot of efforts every day. That can be a challenge, but you can do it soon, you'll enjoy the results of all your hard work: more fun and success at school.

    Over the past few years I've had an uncomfortable sense that someone, or something, has been making changes to my brain. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Involving myself in a book or a lengthy article used to be easy. That's rarely the case any more.

    I think I know what's going on. For over a decade, I've been spending lots of time online. The Web has been a godsend to me as a writer. Research that once required days in the rooms of libraries can now be done in minutes by a few Google searches. Even when I'm not working, I'm scanning headlines or just tripping from link to link.

The Net is becoming a universal medium where information flows through my eyes and ears and into mind. The perfect recall of silicon memory (硅制存储器) can be a blessing to thinking. But that comes at a price. As the media theorist Marshall Mcluhan pointed out, media are not just passive channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is weakening my ability for concentration. Once I was a driver in the sea of words. Now I zip along the surface like a flying swallow.

I'm not the only one. When I mention my troubles with reading to acquaintances, Bruce Friedman, a blogger, also has described how the Internet has changed his mental habits. His thinking has taken on a "staccato (破碎)" quality. "I can't read War and Peace any more" he admitted, "I've lost the ability to do that."

A recently published study suggests that when reading online, we tend to become "more decoders (解码器) of information". We are not only what we read; we are how we read.

    After finishing a meal at an American Chinese restaurant you probably expect to receive a handful of fortune cookies after you pay the bill. Fortune cookies are in Chinese restaurants throughout the United States. It's rather satisfying to crack open a cookie at the end of your meal and read your “lucky fortune” on the slip of paper inside.

    The exact origin of the fortune cookie is unknown. It is thought that the tasty snack was the first introduced into San Francisco in 1914, after an immigrant began distributing the cookie with “thank you” notes in them. These “thank you” notes were intended as symbols of appreciation for friends who stood with him through the economic hardship and discrimination of his early life in America.

    There is an alternate origin story. Los Angeles is regarded as the site of the fortune cookie's invention. In this version of the story, David Jung, a Chinese immigrant residing in L. A., is thought to have created the cookie in order to uplift the spirits of the poor and homeless. In 1918, Jung handed out the cookies for free to the poor outside his shop and each cookie contained a strip of paper with an inspirational sentence printed on it.

    Fortune cookies first began to gain popularity in mainstream American culture during WWII. Chinese restaurants would serve them in place of desserts, as desserts were not popular in traditional Chinese cuisine. Today fortune cookies are not tied to Chinese-American culture. In fact, the largest fortune cookie manufacturer is located in the United States and it produces 4.5 million fortune cookies a day —— an evidence to the modern-day popularity of the snack. However, an attempt to introduce the fortune cookie to China in 1992 was a failure, and the cookie was cited for being “too American.”

    So the next time you break open a fortune cookie and read a fortune about the many successes you should expect in your future, remember that the conclusion to your Chinese restaurant meal may not be as Chinese as you think.

    One day when I was 5, my mother scolded (责骂) me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. When angrily opening the screen door with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no remorse, for I was happy to be playing in the backyard with my toys.

    Today, I know if my child had done what I did, I would have scolded my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. They never said a word. They left the corner of the screen door pushed out, creating an opening, a breach (裂缝) in the defense against unwanted insects.

    For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. I would wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.
