China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I've found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors — silver, green, red, blue, yellow, whatever you want.

    It's fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks. Bicycles allow people the freedom to move about that cars just can't provide.

    Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.

    My first ride home was orderly (守秩序的). To be safe, I stayed with a “pack” of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully.

    Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.

    I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.

    Ownership used to be about as straightforward as writing a cheque. If you bought something, you owned it. If it broke, you fixed it. If you no longer wanted it, you sold it or threw it away. In the digital age, however, ownership has become more slippery. Since the coming of smartphones, consumers have been forced to accept that they do not control the software in their devices; they are only licensed to use it. As a digital chain is wrapped ever more tightly around more devices, such as cars and thermostats, who owns and who controls which objects is becoming a problem. Buyers should be aware that some of their most basic property rights are under threat.

    The trend is not always harmful. Manufacturers seeking to restrict what owners do with increasingly complex technology have good reasons to protect their copyright, ensure that their machines do not break down, support environmental standards and prevent hacking. Sometimes companies use their control over a product's software for the owners' benefit. When Hurricane Irma hit Florida this month, Tesla remotely updated the software controlling the batteries of some models to give owners more range to escape the storm.

    But the more digital strings are attached to goods, the more the balance of control leans towards producers and away from owners. That can be inconvenient. Picking a car is hard enough, but harder still if you have to dig up the instructions that tell you how use is limited and what data you must give. If the products are intentionally designed not to last long, it can also be expensive. Already, items from smartphones to washing machines have become extremely hard to fix, meaning that they are thrown away instead of being repaired.

    Privacy is also at risk. Users become terrified when iRobot, a robotic vacuum cleaner, not only cleans the floor but also creates a digital map of the inside of a home that can then be sold to advertisers (though the manufacturer says it has no intention of doing so). Cases like this should remind people how jealously they ought to protect their property rights and control who uses the data that is collected.

    Ownership is not about to go away, but its meaning is changing. This requires careful inspection. Devices, by and large, are sold on the basis that they enable people to do what they want. To the extent they are controlled by somebody else, that freedom is compromised.

    Are you looking for some new and exciting places to take your kids to? Try some of these places.

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet(木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

    Life is a process. It is said that it doesn't come the same again; it is glad that the same doesn't have to come back again.

    In this life, what did you miss?

    The wife asked the husband when she was 25. Worried, the husband replied, "I missed a new job opportunity."

    When she was 35, the husband angrily told her that he had just missed the bus.

    At 45, the husband sadly said, "I missed the opportunity seeing my close relative before his last breath."

    At 55, the husband said disappointedly, "I missed a good chance to retire."

    At 65, the husband hurriedly replied, "I missed an appointment with the dentist."

    At 75, the wife did not ask the husband anymore, the husband was kneeling in front of the very sick wife. Remembering the question the wife used to ask him, this time he asked the wife the same question. The wife, with a smile and peaceful look, replied, "In this life, I did not miss having you!"

    The husband was full of tears. He always thought that they could be together forever. He was always busy with work and something unimportant. So much had he never been thoughtful to his wife. The husband hugged the wife tightly and said, "Over 50 years, how I had allowed myself to miss your deep love for me."

    In the busy city life, there are many people who are always busy with work. These people are busy with their jobs, and sacrifice all their time and health to meet the social expectations. They are unwilling to spend time on health care. They miss the opportunity to be with their children in their growing up. They neglect the loved ones who care for them, and also their health.

    Nobody knows what is going to happen one year from now. Life is not permanent, so always live in the now.

    Arthur Miller(1915-2005) is universally recognized as one of the greatest dramatists（剧作家） of the 20^th century. Miller's father had moved to the USA from Austria-Hungary, drawn like so many others by the “Great American Dream”. However, he experienced severe financial hardship when his family business was ruined in the Great Depression (大萧条时期) of the early 1930s.

    Miller's most famous play, Death of a Salesman, is a powerful attack on the American system, with its aggressive way of doing business and its insistence on money and social status as indicators (标志) of worth. In Willy Loman, the hero of the play, we see a man who has got into trouble with his system, Willy is “burnt out” and in the cruel world of business there is no room for sentiment (情绪): if he can't do the work, then he is no good to his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at a loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end.

    When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics' Circle Award, and the Pulitzer Prize for drama. It was the first play to win all the three of these major awards.

    Miller died of heart failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005, the 56^th anniversary of the first performance of Death of a Salesman on Broadway.

    Although toys packaging says it's educational, it doesn't make it so. That's the finding from a new study in JAMA Pediatrics that found some toys being marketed as language promoters got in the way of learning.

    Research shows that for kids to understand, speak and eventually read or write a language, they need to hear it - lots of it. And it's never too early for parents and to caregivers to get talking. That explains the booming industry in talking electronic toys that claim to help kids learn language.

    Professor Anna Sosa, of Northern Arizona University, led the study and says she gave families three different kinds of toys to play with: books, traditional toys like humble blocks and a shape sorter, and electronic toys. Sosa says she picked those toys because they are advertised in their packaging as language-promoters for babies between the ages of 10 and 16 months.

    "We had a talking on farm-animal names and things," Sosa says of the electronic toys. "We had a baby cell phone. And we had a baby laptop. So you open the cover and start pushing buttons, and it tells you things. The parent-child couples were asked to play separately with each type of toy over the course of three days."

    "When there's something else that's doing some talking, the parents seem to be sitting on the sidelines and letting the toy talk for them and respond for them," Sosa says. "That's bad because the best way a toy can promote language in infants and toddlers is by stimulating interaction between parent and child. There's simply no evidence that a young child can learn language directly from a toy. It isn't responsive enough. It isn't social."

    As for the other toys, traditional blocks and puzzles stimulated more conversation than the electronic toys, and books outscored them all. But don't underestimate the humble block. While traditional toys fell short of books in interaction quantity, Sosa notes, they kept pace in terms of quality.
