In the 1962 movie Lawrence of Arabia, one scene shows an American newspaper reporter eagerly snapping photos of men robbing a damaged train. One of the robbers, Chief Auda abu Tayi of the Howeitat clan, suddenly notices the camera and snatches it. “Am I in this?” he asks, before smashing it open. To the dismayed reporter, Lawrence explains, “He thinks these things will steal his virtue. He thinks you're a kind of thief.”

As soon as colonizers and explorers began taking cameras into distant lands, stories began circulating about how native peoples saw them as tools for black magic. The “ignorant natives” may have had a point. When photography first became available, scientists welcomed it as a more objective way of recording faraway societies than early travelers' exaggerated accounts. But in some ways, anthropological(人类学的) photographs reveal more about the culture that holds the camera than the one that stares back. Up into the 1950s and 1960s, many ethnographer(人种学者) sought “pure” pictures of “primitive” cultures, routinely deleting modern articles for daily use such as clocks and Western dress. They paid men and women to re-enact rituals or to pose as members of war or hunting parties, often with little regard for truthfulness. Edward Curtis, the legendary photographer of North American Indians, for example, got one Makah man to pose as a whaler with a spear in 1915 — even though the Makah had not hunted whales in a generation.

    These photographs reinforced widely accepted stereotypes that native cultures were isolated, primitive, and unchanging. For instance, National Geographic magazine's photographs have taught millions of Americans about other cultures. As Catherine Lutz and Jane Collins point out in their 1993 book Reading National Geographic, the magazine since its founding in 1888 has kept a tradition of presenting beautiful photos that don't challenge white, middle-class American conventions. While dark-skinned women can be shown without tops, for example, white women's breasts are taboo. Photos that could unsettle or disturb, such as areas of the world torn apart by war or famine, are discarded in favor of those that reassure, to conform with the society's stated pledge to present only “kindly” visions of foreign societies. The result, Lutz and Collins say, is the display of “an idealized and exotic world relatively free of pain or class conflict.”

    Lutz actually likes National Geographic a lot. She read the magazine as a child, and its lush imagery influenced her eventual choice of anthropology as a career. She just thinks that as people look at the photographs of other cultures, they should be alert to the choice of composition and images.

    When a dog looks at you with big puppy-dog eyes, it's hard for you to go away, and you may speak out “Awww” without hesitation. However, there's a reason why you find a dogs stare so attractive. That sweet stare actually causes the release of a particular hormone, or chemical messenger in the body. This hormone creates feelings of affection in humans. The same thing happens to dogs when people look back at them. Scientists believe this helps people and their four-legged friends bond, or feel connected. Scientists have wondered what causes dogs to lovingly stare at their owners. To find out, a team of researchers from Azabu University in Japan studied 30 owners and their dogs.

    The researchers found that after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催产素). One key role of this hormone in many animals is to promote bonding, like that between a mother and newborn. The increase of oxytocin didn't happen, though, when scientists repeated the experiment with wolves and the humans who had raised them.

    A second experiment also found that if dogs were given oxytocin, they looked at their owners longer. Scientists aren't sure exactly why, but this reaction occurred only with female dogs. Their owners oxytocin levels also rose as a result.

    The result of these experiments might help answer an age-old question: How did the fearsome wolf ancestor of modern dogs turn into man's best friend? Takefumi Kikusui, an animal scientist who worked on the study, thinks that the change happened when dogs first became domestic (驯养的).

    According to Kikusui, there may have been a small group of wild dogs that were naturally friendlier. “Humans are very sensitive to eye contact. By using this special communication tool, the dogs are able to win over our hearts. If they are more likely to make eye contact, it would be easier for them to bond with dog owners,” Kikusui said.

    As a young adult, Noah Webster was a teacher. At that time, the colonies were fighting for independence from Britain. Yet the books that American children used in school all came from Britain. The books were all about British people and British places. Webster wanted books that would mean more to American children. So he wrote three books that used American examples—a grammar book, a spelling book, and a reader. These books were very popular, and millions of them were sold.

    Webster was interested in changing the spellings of words. He wanted words to be spelled the way they were pronounced. For example, he thought the word "head" should be spelled "hed", and the word "laugh" should be spelled "laf". People liked Webster's suggestions.

    However, few words were actually changed. One group of words that were changed were words in which an unpronounced "u" followed an "o". That is why Americans write "color" and "labor", and the British write "colour" and "labour".

    With the money he made from his books, Webster was able to write. It was the first American English dictionary, published in 1828.Webster's dictionary had over 70，000 words and gave the meaning and origin of each. To this day, Webster's work is the example that most dictionaries of American English follow.

    When I was a kid, I was the girl who kept the training wheels on my bike as long as possible. Even my younger sister had got rid of them much earlier than me. But as I began to grow older, this changed.

    All this happened on the Bike Safety Day. It is supposed to be a fun day at school when all of us kids bring our bikes to school and the school provides us with the opportunity to ride outside and learn proper bike safety. Sounds like fun, right? No. In fact, it caused me to panic. What was I going to say when my friends asked me about my training wheels?

    With the pressure of everyone seeing my training wheels, I determined to let them go. This was the first big change I'd ever made on my own.

    I went to my parents and told them all about my dilemma. They were more than happy to help. We went outside and got my bike. Instead of running away and hiding behind, I stood in front of my bike and took great pride in my decision as my dad removed the training wheels.

    I got on and steadied myself. My heart raced but my feet and hands were calm. My dad started to push before my feet even moved and suddenly I was off. The fear faded away and a relaxed mind came into its place. It was crazy to think how quickly I learned something that took so long for me to even try!

    My confidence soared. This was going to be the start of a brand new world for me. My accomplishment would carry me forth to new goals and wins. I realized that if I set my mind to something, I could achieve it.

    All around the world, lawyers generate more hostility(敌视) than the members of any other profession-with the possible exception of journalism. But there are few places where clients have more grounds for complaint than America.

    During the decade before the economic crisis, spending on legal services in America grew twice as fast as inflation. The best lawyers made skyscrapers-full of money, tempting ever more students to pile into law schools. But most law graduates never get a big-firm job. Many of them instead become the kind of nuisance-lawsuit filer that makes the tort system a costly nightmare.

    There are many reasons for this. One is the excessive costs of a legal education. There is just one path for a lawyer in most American states: a four-year undergraduate degree in some unrelated subjects, then a three-year law degree at one of 200 law schools authorized by the American Bar Association and an expensive preparation for the bar exam. This leaves today's average law-school graduate with $100,000 of debt on top of undergraduate debts. Law-school debt means that they have to work extremely hard.

    Reforming the system would help both lawyers and their customers. Sensible ideas have been around for a long time, but the state-level bodies that govern the profession have been too conservative to implement(实施)them. One idea is to allow people to study law as an undergraduate degree. Another is to let students sit for the bar after only two years of law school. If the bar exam is truly a strict enough test for a would-be lawyer, those who can sit it earlier should be allowed to do so. Students who do not need the extra training could cut their debt mountain by a third. The other reason why costs are so high is the restrictive guild-like(行会) ownership structure of the business. Except in the District of Columbia, non-lawyers may not own any share of a law firm. This keeps fees high and innovation slow. There is pressure for change from within the profession, but opponents of change among the regulators insist that keeping outsiders out of a law firm isolates lawyers from the pressure to make money rather than serve clients ethically.

    In fact, allowing non-lawyers to own shares in law firms would reduce costs and improve services to customers, by encouraging law firms to use technology and to employ professional managers to focus on improving firms' efficiency. After all, other countries, such as Australia and Britain, have started liberalizing their legal professions. America should follow.
