    In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this：A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."

    The city planner decided to build an underground drainage （排水） system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews （螺旋千斤顶） beneath the building's foundation. One man was assigned to operate each section of roughly 10jackscrews.At Pullman's signal each man tured his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening.

    Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

    Moments before I could lift my case to put it in the plane's overhead locker ahead of our recent holiday to Europe, my father gently urged me to stop. He held the thick handles of the case and lifted it with his thin arms, pushing it into place with a sigh. “You should relax and be the lady, and let me do the heavy tasks,” he said seriously. “In the future, someone special will come into your life and take over such tasks from me, but that will never happen if you do everything yourself.”

    I was stunned into silence. This was not the father I remembered from childhood, who trained me to study hard at school, asked me to earn my own pocket money as a teenager at a local coffee shop, and even taught me household chores so that my life alone in London wouldn't turn into a mess. But then, eight years after I left home and started a new life in the UK, I realized for the first time that my dad still has expectations for me to be like a princess and to stay dependent and delicate, which were considered necessary qualities of women in traditional China.

    Well, that came a little late. Little did Dad know that over the three years of my university life, I moved flats five times all by myself, dragging suitcases of books and clothes, and waiting for the taxi in the rain while holding tight onto cardboard boxes. Meanwhile, living in the UK – a country currently led by a female prime minister – I have never thought there is anything girls cannot do. Most of my female friends are professionals working in the City of London, and after work, we frequently go down to the pub for a drink, just like the guys do – something my mother never did.

    I wondered how I might make Dad understand the new world his little girl has entered. Perhaps one day, he will realize the “someone special” in my life will appreciate my confidence and independence above dependence, and admit that times have changed.

    The Taj Mahal, in Agra, India, is one of the most brilliant structures on Earth. It is nearly 400 years old. Emperor Shah Jahan had it built in memory of his wife. It took about 20 years to build the monument. Some 20,000 workers and 1,000 elephants helped get the job done. Today, the Taj Mahal is not just a symbol of cultural history. It's also India's most famous tourist attraction. About 8 million people visit it each year.

    But pollution is turning the white marble monument shades of green, yellow, and brown. The Taj Mahal stands on the polluted Yamuna River. Insects are attracted to the dirty water. They leave greenish droppings on the building. Air pollution is also a big threat. Factories and cars release pollution into the air. It sticks to the Taj Mahal's suidEace. In the 1990s, India's Supreme Court ordered hundreds of factories near the monument to close. Also, car and bus traffic was restricted. From time to time, workers clean the Taj Mahal. But doing so is difficult, expensive, and time-consuming. And it doesn't prevent the discoloration.

    On July 11, India's Supreme Court gave the city of Agra a warning: "Either you destroy the Taj Mahal or you restore it". Authorities in the city submitted a draft of an action plan on July 24. It suggests banning plastics and construction from the area. It also calls for the closing of more factories.

    "In order to preserve the Taj Mahal, people must come together to work toward a solution. There needs to be positive pressure on people to act. We need to act immediately," Sachchida Tripathi says. He worked on a 2014 study of pollution at the Taj Mahal. "We are trying," he adds, "but we need to try more."

Workers are returning to their careers, or starting new ones after age 65.

More than ever, work is where many of us get our sense of purpose. That doesn't end at age 65. After being retired for only three months, Sue Ellen King returned to work at the University of Florida Health in Jacksonville, Florida, where she had been a care nurse and nursing educator for 38 years. She is now working part-time in a position created just for her. "It's perfect," she told The New York Times. "I get the satisfaction of having people appreciate what I do." With the average lifespan for those who reach age 64 now getting all the way to 84 years old, those who reach retirement age still have many potential years of work to go.

Job sites connected toward part-timers, temporary positions, and some can also turn up opportunities that may lead to longer-term work. Fred Dodd tried a part-time job after his unemployment as a clerk for large banks at age 63. He'd thought about retiring then. "But part of me just wanted to keep working partly for the money, but more just because I felt I wanted to do more in my career, " he said.

The retired have the advantage of not needing to focus on the earnings potential of whatever jobs they take on, so these older workers are attracted to more meaningful work. And since they are voluntarily putting their skills and experience to good use, they may well have more flexibility than mid-career people. Two-thirds of retirees who'd come back to the work world were doing meaningful work they enjoyed. Legal work and community service were popular choices, as was teaching—all areas in which older workers might have an opportunity to make their own schedules.

Earning more money rarely seems like a bad idea, but it can cause issues for retirees, including effects when they claim Social Security (申请社会保障) benefits early.

Bogre Udell, who speaks four languages, met Frederico Andrade, who speaks five, at the Parsons New School in New York City.In 2014, they started a project to make the first public records of every language in the world.They've already recorded more than 350 languages, and plan to hit 1，000 in the coming years.

"When humans lose a language, we also lose greater diversity (多样化) in art and traditions，"said Bogre Udell.Between 1950 and 2010, 230 languages disappeared.Today, a third of the world's languages have fewer than 1，000 speakers left.Every two weeks a language dies with its last speaker, and 50 to 90 percent of them are said to disappear by the next century.

Wikitongues has asked for volunteers in 40 countries to film native speakers talking in the past, present，and future tenses of their mother languages.Native speakers are asked to recall childhood, share their stories, and discuss their hopes and goals.One volunteer in the South Pacific islands of Vanuatu recorded a language that had never been studied by language experts before.Another volunteer found a speaker of Ainu, a language in Japan that has no relation to any other known language, and he also recorded it.However, priceless recording opportunities disappear regularly.Not long ago, one of the last two speakers of a Saami language in the Russian steppes died right before his recording session with Wikitongues.

A lack of protection and globalization are responsible for diminishing language diversity.For much of the 20th century, governments across the world forced some local people to use official languages.More than 100 languages in Australia have disappeared since European settlers arrived.However, most languages die today because of other factors; climate change and urbanization contribute (是……的原因之一) greatly to the disappearance of languages.
