    One of the greatest gifts one generation can give to other generations is the wisdom it has gained from experience. This idea has inspired the award-winning photographer Andrew Zuckerman. He interviewed and took photos of fifty oversixty-fiveyearsold all over the world. His project explores various aspects of their lives. The photos and interviews are now available on our website.

    Let us now have a culture of peace.——Federico Mayor Zaragoza, Spain Federico Mayor Zaragoza obtained a doctorate in pharmacy (药学) from the Complutense University of Madrid in 1958. After many years spent in politics, he became Director General of UNESCO in 1987. In 1999, he created the Foundation for a Culture of Peace, of which he is now the president. In addition to many scientific publications, he has published four collections of poems and several books of essays.

    Writing is a discovery.——Nadine Gordimer, South AfricaDue to a weak heart, Nadine Gordimer attended school and university briefly. She read widely and began writing at an early age. She published her first short story at the age of fifteen, and has completed a large number of works, which have been translated into forty languages. In 1991, Gordimer won the Nobel Prize for Literature.

    Most people would say the sea is blue and green. But the people who live near the coast of Zhejiang may say it is red. It is not people who caused the colour change, but very small living thing in the sea. They are algae(藻类)and protozoa(原生动物). They come in many different colours; red, yellow or brown. Red is the easiest of those to see so when this happens people call it a “red tide.”

    Red tides only happen when conditions in the sea are right. In the past few years, factories and people have been putting more chemicals into the sea. These chemicals help algae and protozoa to grow very quickly. The temperature of the sea is also important. Red tides usually happen at 20 to 30 degrees Celsius. Red tides often happen in dry, warm areas where there is little wind. Living things grow easily in these places. Sometimes fishermen help red tides by mistake. They put small sea animals into the water for food to help fish grow.

    Those living things do more than change the colour of the water-they also put poison and mucus(黏液)into the sea. This is had for fish. The poison is bad for their brains. And too much mucus in the sea fills up fish's gills(鳃) so they can't breathe. Lots of dead fish and other sea animals are now washed up on Chinese beaches.

    Red tides can be bad for people too. We shouldn't eat fish from red-tide waters. The algae gets inside of fish and it smells bad. It can make your eyes water. If people eat fish with too much algae inside they could die.

    Fishermen in Zhejiang are having a hard time right now. Because of the red tide, they are selling 30% less fresh seafood than usual.

    In China red tides usually happen in May and June around places like Fujian Guangdong and Hong Kong.

    Many other countries sometimes also have red tides. But it seems that we have few ways to stop red tides. They can last as long as 16 months.

    Mid-afternoon on a particularly busy Tuesday, I took leave of my desk at work and walked into a local Starbucks only to find a space where neither my clients nor my children would ask me to do something.

    Inside, I ran into Kate, a co-worker of mine. The topic of parenthood came up. I complained about how packed my schedule was. From the minute I woke up to the minute I fell asleep, I was constantly in demand and always had someone knocking at the door. But a bit of sadness seemed to come over Kate's face.

    "Well, my daughter's in San Francisco and she doesn't seem to need me at all these days," Kate said. It was in that moment that I realized although I might often feel in high demand, there will come a day when I will actually miss that same stress I then complained about.

    And as our conversation continued, it turned to our children's younger years, with Kate smiling proudly, thinking of the little boy and girl she raised who are now a man and a woman. But I noticed her smile was marked with regret. She explained that she often wondered about what she could have done differently when her children were in their earlier years.

    This got me thinking. Is regret an unfortunate footnote (注脚) to parenthood? With that in mind, I asked six older parents one question: What is your biggest regret from your early days as a parent?

    It turned out that all of them thought they could have done it better. But, each of them also has a strong, healthy relationship with their kids. Whatever regrets their parents might have had about their upbringing, one thing is clear —— it didn't affect them in a meaningful way.

    The bottom line is, we all feel like we could be doing this parenting thing better. And quite clearly, years later, we're still going to look back and wish we tried things differently. But the past can't be changed, and neither should it.

    Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods.

    Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers.

    Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

    Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. So unless the government has a good system of control, or can educate the people, the forests slowly disappear.

    This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are no trees, the rainfalls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich top soil in which crops grow. When all the top soil is gone, nothing remains but worthless desert.

    Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.

    Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.

    But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.

    For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.

    "Even a modest amount of steps is associated with lower death rates," said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.

    The study had a few limitations. For example, the researchers only measured women's movements once, at the start of the study period. It is possible that the women's behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.

    "Any walking is better than nothing," Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.
