“We are good mothers,” I said to my friend, as we sat on our comfortable beach chairs under our beach umbrella and watched our children playing in the waves.

    Out of nowhere, the children took off running. About fifty yards from us, a man—maybe in his fifties—was fishing. The children stood next to him and watched with their little mouths hanging open as he cast the fishing lines. He smiled at them. They ran back to us—all except my three-year-old daughter, Drew.

    My heart beat fast with horror. “Drew! Come here! Play with your friends!” I shouted, very aware that my speeches about not talking to strangers weren't working. It seemed that many parents heard of horrible stories about children being taken away by strangers. Responsible mothers should teach their children that the world is a dangerous place. So I felt relieved (松口气) when Drew ran towards me and took hold of a shovel (铲子). Then she looked me in the eye: “I want to be with the person.”

    Again, she approached the middle-aged man, and started digging next to him.

    Several seconds later, she returned, waving something shiny.

    “Look, Mommy! A toy fish!”

    It was, indeed, a toy fish—yellow and rubber. This must have been what he was using to attract the fish. And he'd given it to Drew. The three other children were deeply impressed, and they didn't try to hide how jealous(妒忌的)they were—clearly, they all wanted the fish.

    “My friend gave me that fish!” Drew shouted loudly. The sand in front of the umbrella turned into a preschool cage match with a yellow rubber fish flying through the air. I felt like I might cry myself.

    Unexpectedly, there he was: the man, standing right next to us with three more rubber fish in hand. He handed them to each of the children. By their faces, you would have thought he was actually the really kind big brother.

    “Thank you,” I said, realizing that there is good and kindness in strangers.

    Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast.

    The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight instead of losing it. You will lose more weight if you reduce your other meals.

    When Dee Dee Bridgewater learned that she would become a 2017 NEA Jazz Master, a series of thoughts and feelings flooded her mind. “It was so far out of my orbit and just my whole sphere of thinking,” she said in a conversation at NPR this spring, hours before she formally received her award.

    She's 66-far from retirement age in jazz, and on the extreme forward edge of the NEA Jazz Masters people. So she was aware of her relative youth in the field She also recognized that there haven't been many women in the ranks of NEA Jazz Masters: fewer than 20, out of 145. That idea led her to reflect on her predecessors (前任): legendary singers like Betty Carter* who was seated back in 1992, and Abbey Lincoln, who received the nod in 2003.

    Bridgewater sought inspiration and advice from both Carter and Lincoln, as she recalls in this period of Jazz Night, which features music recorded during the season opener for Jazz at Lincoln Center. On a program called “Songs of Freedom”, organized by drummer Ulysses Owens, Jr., Bridgewater sang material associated with Lincoln as well as Nina Simone: an extremely angry song of the civil rights movement, like “Mississippi Goddam”.

    A separate concert, “Songs We Love”, found Bridgewater singing less politically charged (but still exciting) fare like “St. James Infirmary”, which appears on her most recent album. In words as well as music, this period reveals how seriously Bridgewater takes that responsibility, seeing as how it connects to her own experience in the jazz lineage. But maybe “seriously” isn't the right word when it comes to Dee Dee, whose effervescence (欢腾) shines through even in a reflective mood. Join her here for a while; she's excellent company, no more or less so now that mastery is officially a part of her resume.

    To eat only a vegan（素食的） diet might sound difficult, especially with many popular dishes containing meat or other animal products. Yet in 2017, veganism was described as “the fastest - growing lifestyle movement” in the UK, according to BBC news.

    A study by a UK market research organization, suggests that over 542,000 Brits went vegan during the previous decade, an increase of 360%. And the main force behind this increase was those aged 15-34 years old — 42% of recent vegans fall under that age range.

    So why exactly has veganism become so popular among young Brits?

    One reason could be that many young people want to protect the environment, as less meat consumption is known to be beneficial to the environment. Global meat manufacturing is believed to cause 18% of the world's greenhouse gas emissions（排放）, even more than that of all the world's cars, trains and planes combined. Another reason is that many of today's young people believe that it's wrong to kill animals to be used as food.

    Jess Murray, 22, a student at University College London, said that he chose to become vegan after realizing that eating animals is a choice that people make, rather than something that we need to do to survive. “Becoming vegan was an ethical (道德的) decision,” he told the Guardian.

    Social media is also believed to have given rise to the increase in veganism. Platforms such as Facebook allow young vegans to connect with each other much easier, while others such as Instagram have led to the creation of “vegan celebrities (名人)”, who share lips on vegan lifestyles.

    Despite the rising of veganism, Laura Wyness, an expert in diet and nutrition, said that meat is very important for people's health. “A strict vegan diet makes it difficult to get some minerals and vitamins that your body needs,” Wyness told BBC news.

    However, the popularity of veganism doesn't seem to be fading. “It feels more like this is something that is sticking.” said an expert of the Vegan Society, a UK charity that promotes veganism.

    Perhaps no one knows the power of imagination better than Chinese writer Liu Cixin. Until four years ago, Liu worked full-time as a computer engineer at a power plant in Shanxi province. He only wrote science fiction in his spare time. But it was during this time that Liu's imagination took flight. He did what he might never have the chance to do in real life – wander in space, fight with aliens, and visit planets light-years away.

    But even with such a powerful imagination, Liu, 55, probably hadn't expected that he would become the first Asian to win the Hugo Award, science fiction's highest prize, in 2015. Perhaps neither did he think that former US president Barack Obama would read his novel The Three-Body Problem, nor that on Nov 9 in Washington DC, he would win the 2018 Arthur C. Clarke Award for Imagination in Service to Society. It's the first time a Chinese writer has ever won the award.

    In his acceptance speech, Liu said that he owed his imagination to Arthur C. Clarke (1917-2008), a famous UK sci-fi author. He said that reading Clarke's 1968 classic novel 2001: A Space Odyssey in the early 1980s had a great effect on him.

    “My mind opened up like never before. I felt like a narrow river finally seeing the sea,” Liu said. “That night, in my eyes, the starry sky was completely different from the past. For the first time in my life, I was awed (使……敬畏) by the mystery of the universe.”

    But no matter how far away Liu's imagination takes him, somehow his novels always stay rational.

    In The Three-Body Problem, for example, Liu tells a tale of aliens invading Earth. But unlike other alien stories, Liu talks more about relationships between civilizations(文明), rules of survival, and the meanings of life. And in The Wandering Earth, Liu looks ahead to the day when our solar system comes to an end and humans have to look for a new place to live. However, all his visions and solutions are based on “hard science”. Liu's works aren't simply daydreams.
