Once a boy came to ask a fisherman how to become cleverer, because his mother always called him “foolish boy”.

    “That's easy,” answered the fisherman. “I know one way to make you become cleverer.”

    “Really?”

    “Of course. It is said a fish head is good for brain. If you eat one, you'll become cleverer indeed. Pay only three pounds for one fish head.” The boy paid him three pounds and the fisherman cut off a fish head and handed it to him.

    A raw fish head is not good—not even for a hungry boy to eat but the boy ate it up in  two gulps.

    “Do you feel anything?” asked the fisherman.

    “Not in my head,” said the boy.

    The boy lay on the ground and thought. “One whole fish costs only two pounds. I have paid him three pounds for the fish head. Why couldn't I have the whole fish for soup, a head for brain and one pound left over?” He jumped up and shouted at the fisherman. “You thief! You are fooling me!” The fisherman laughed, saying, “The fish head works now, you see.”

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below，who do you think was the most important woman of the past 100 years?

Jane Addams (1860－1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931，Addams became the first American woman to win the Nobel Peace Prize.

Rachel Carson (1907－1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book SilentSpring raised awareness of the danger of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

Sandra Day O'Connor (1930－present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and，in 1981, the first woman to join the U．S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

Rosa Parks (1913－2005)

    On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil ­ rights movement. “The only tired I was, was tired of giving in，”said Parks.

    China is known as a state of manners and ceremony. Many proverbs have been passed down from generation to generation such as "polite behavior costs nothing" or "showing respect each other" and so on. For instance, there is an interesting short story. Once upon a time, a man went on a long tour to visit his friend with a swan as a gift. But it escaped from the cage on the way. Though he tried hard, he got hold of nothing but a feather. Instead of returning home, he continued his journey with the swan feather. When his friend received this unexpected gift, he was deeply moved. And the saying "The gift is nothing much, but it's the thought that counts." was spread far and wide.

    Chinese used to cup one hand in the other before the chest as a greeting. This tradition has a history of more than 2, 000 years and nowadays it is seldom used except in the Spring Festival. And shaking hands is more popular. Bowing, as to show respect to the higher level, is often used by the lower like subordinates(下级), students, and attendants. But at present Chinese youngsters prefer to simply nod as a greeting.

    When you start a talk with a stranger, the topics such as weather, food, or hobbies may be good choices to break the ice. For a man, a chat about sports, stock market or his job can usually go on smoothly. Similar to Western customs, you should be careful to ask a woman private questions. However, relaxing talks about her job or family life will never put you into danger. Though Chinese are said to be implicit(含蓄的), they are actually humorous enough to be pleased about the jokes of Americans.

Young Americans Are Less Wealthy Than Their Parents

    The cost of living in the United States is going up, notes writer Alissa Quartz. As is reported in New York Post, Quartz points to "the costs of housing, education and health care in particular." At the same time, a new study, the report of which is called "The Fading American Dream" found that half of Americans born in the 1980s are falling behind their parents economically.

    These findings show that many younger adults are experiencing "downward mobility." In other words, they are not doing as well economically as their parents were at the same age. The idea of downward mobility is especially troubling for Americans, writes Robert Samuelson in The Washington Post. He says most U.S. citizens believe that, over time, the amount of money they earn will rise and life will get easier.

    Alissa Quartz wrote a book about the financial difficulties of Americans. In the book, Quartz tells about teachers who are struggling to pay for regular costs. One high school teacher drives for ride sharing service Uber at night to earn more money. He corrects students' papers between riders.

    A college professor turned to government assistance to feed her child and pay for a doctor. Quartz says even lawyers increasingly cannot earn an income that enables them to meet their needs. The problem of decreasing incomes in their field is made worse by debt they may have from law school. Quartz and the economists who studied these issues say many things have led to lower incomes and downward mobility. The economic recession(衰退) of 2007 to 2009 is partly to blame, they say. Modern technology also plays a part. Quartz says robots threaten to reduce the earnings of health care workers, reporters, and people who work at supermarkets, drug stores and tax preparation services. In The Washington Post, Robert Samuelson noted that poor schools, a weak housing industry and too many government rules are also to blame.

    With all these things, and more, partly responsible, what is the solution? These experts say the answer is complex. But all point to one issue that needs to be examined: economic inequality. Quartz writes that while America is one of the richest countries in the world, it also has one of the biggest divides between the wealthy and the poor.

    The researchers in "The Fading American Dream" study make a similar observation. They say raising GDP will not significantly improve the economic situation of most Americans. A higher GDP may help only those who are already doing well. Instead, the economists say, the United States could try to repeat something Americans born in the 1940s experienced. As those children grew up, they almost all benefited from a better economy.

    Like any new ninth-grader on the first day of school, Joemar Class had ninth-grader- emotion (情绪). He's not used to school in Hartford. He's used to going to school in his home town of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso," he said in Spanish.

    We first met Joemar in mid-October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm—Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16-year-old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz—the school's program director.

    "I see you have new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day?"

    Then he met couple of teachers.

     "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then Levitz took him on a quick tour of the school before classes began—to her office the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's little worried," Guillermo said as we left." But, at the same time, he's looking forward to it."

When it comes to sitting properly, we all know the correct way even if we don't do it to the letter. No crossed legs, bottoms touching the back of the chair and feet on the ground. But even if you're doing it right, sitting for long periods is shockingly bad for you. It has been described as the new smoking, linked to heart disease and even cancer. There is no doubt we should all try to do less of it. But perhaps we could also do it better.

A classic survey, published in 1953, described 100 different sitting postures adopted by 480 cultures around the world. Among the most common were sitting cross-legged, kneeling and the deep squat (深蹲), with feet flat on the ground and bottoms resting on or just above it. Even in Western cultures, these are preferred sitting positions among young children. But Westerners tend to prefer chair use from an early age, insisting children sit on seats in school.

One big problem with this desire for chairs is that they make sitting so, well, sedentary (久坐不动的). Consider the Hadza, a group of hunter-gatherer people in Tanzania. They spend around 9 hours a day sitting. However, they squat and sit on the ground in various positions, and this involves high levels of muscle activity. The supportive nature of chairs, with their high backs and armrests, removes this effort perhaps the reason that people love them.

So what's the best way to sit? Josette Bettany-SaItikov at Teesside University, UK has found that kneeling can help keep the spine in a better position as does squatting. We might also take inspiration from traditional cultures like the Hadza. "Use a variety of postures and preferably not just still postures but some which allow movement," says Bettany-Saltikov.

Bettany-Saltikov believes that we should be rethinking what it means to do a desk job. "We still need to design workplaces that enable people to be productive while being lightly active, like with under-table cycling or walking desks," she says. For now, if your job is sedentary, don't forget to stand up regularly and move around.
