According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people's rank in society.

    Class means a person's economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning $500,000 a year and a bus driver earning $50,000 a year both regard themselves as the middle class!

    Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class. To our knowledge, there aren't too many people who aren't millionaires in the U．S. Senate!

    Status is the honor or respect attached to a person's position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.

    Samuel Osmond is a 19-year-old law student from Cornwall, England. He never studied the piano. However, he can play very difficult musical pieces by musicians such as Chopin and Beethoven just a few minutes after he hears them. He learns a piece of music by listening to it in parts. Then he thinks about the notes(音符) in his head. Two years ago, he played his first piece Moonlight Sonata（奏鸣曲）by Beethoven. He surprised everyone around him.

    Amazed that he remembered this long and difficult piece of music and played it perfectly, his teachers say Samuel is unbelievable. They say his ability is very rare, but Samuel doesn't even realize that what he can do is special. Samuel wanted to become a lawyer as it was the wish of his parents, but music teachers told him he should study music instead. Now, he studies law and music.

Samuel can't understand why everyone is so surprised. "I grew up with music. My mother played the piano and my father played the guitar. About two years ago, I suddenly decided to start playing the piano, without being able to read music and without having any lessons. It comes easily to me —I hear the notes and can bear them in mind—each and every note," says Samuel.

Recently, Samuel performed a piece during a special event at his college. The piece had more than a thousand notes. The audience was impressed by his amazing performance. He is now learning a piece that is so difficult that many professional(专业的) pianists can't play it. Samuel says confidently, "It's all about super memory—I guess I have that gift."

    However, Samuel's ability to remember things doesn't stop with music. His family says that even when he was a young boy, Samuel heard someone read a story, and then he could retell the story word for word.

    Samuel is still only a teenager. He doesn't know what he wants to do in the future. For now, he is just happy to play beautiful music and continue his studies.

A Chinese legend—A pretty maiden is trapped by a dragon. A prince must slay（杀死）the dragon to save her. Then, magically, they fall in love and live happily ever after. Traditional stories tend to emphasize the fantastic, magical side of love. Fate plays matchmaker. Strangers see each other from across a room and instantly know that they are destined to be together.

    It isn't difficult to imagine two strangers coming together and falling in love despite their differences. It suggests that love is challenging, uncertain, and incomprehensible.

    But with more people using online dating services, a very different kind of love has emerged: one that is scientific, convenient, and self-directed. It minimizes risk and provides a choice, like on a menu. There is anonymity（匿名）and the avoidance of immediate rejection. Meeting terms are negotiated online.

    Online dating also allows the setting of preconditions. Computer algorithms（推算） exclude undesirable traits such as the wrong hair color, race, or age. But they also exclude randomness. They reduce the chances of meeting someone different, or someone who could challenge one's romantic ideals. Instead, they find the partner we think we want and exclude everyone else. As a result, we could be missing the opportunity of a lifetime, to meet someone we would never have expected to fall in love with.

    Perhaps this new way represents a more efficient form of romance. Traditional ideas of love may be enchanting - but are they useful? Loneliness and boredom are less exciting than chance encounters, but they represent the more realistic side of love. All too often people have suffered through bad dates and humiliations. If they could just choose what they wanted, wouldn't it save time and reduce suffering? However, by choosing partners based on our preconceived ideas, we may be indulging in our illusions. Instead of letting ourselves grow with someone, love becomes more about looking for ourselves in the other. What if we don't know ourselves as well as we think? Perhaps love isn't about knowing what we want. Perhaps it's about being open to unimagined possibilities.

    When country music star Jackson Maine stops at a bar for a drink after a concert, he's both entertained and attracted by young nightclub singer Ally. He discovers that she writes songs as well as being a talented singer, but hasn't had a break because of her looks.

    One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.

    A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, she'll fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4,000 flowers, and yet will produce only one-twelfth of a tea spoon of me.

The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.

Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return..
