    She was walking home from work one evening when she got the idea. Rosa didn't like her job at the factory, but it was better than no job at all. So, while she was trying not to think about work, she saw the pots in an alley. They were cheap plastic pots, but there were dozens of them piled up behind the flower shop. Such a waste, she thought. When the pots were still there three days later, Rosa went in and asked if she could take some. The flower shop lady said she didn't mind, so Rosa carried home a tower of pots, pretending she was a circus performer on the way.

    At home, Rosa set them on the fire escape outside her tiny apartment. And there they sat. Once a gust of wind sent them slipping to the street three floors below, and she had to go to run after and catch them before the gathering storm.

    Every day, Rosa went to work and thought about her pots- She was wailing for something, but she had patience.

    At last, the newspaper brought good news. A hardware store had a sale on potting soil. Rosa carefully counted her money, then walked six blocks to the store. She bought six bags and carried them home. She bought seeds, too. Rosa slept well that night and dreamed of masses of flowers and fat, glowing fruits,

    Sundays were always good days. Rosa didn't have to work on Sundays. But Rosa couldn't remember when she had had such a good Sunday. She got up early and ate her breakfast on the fire escape with her pots. Then, she began to put dirt into the pots. She sang a little song until all six of her bags of soil were empty. Then, she laid her precious seed packets out and planned her garden. Tomatoes for the biggest pots, and peppers for the next-biggest ones. Flowers in all the rest.

    At the end of the day, Rosa sat in her garden and watched the sunset. Soon, she thought, there will be masses of flowers and fat, glowing fruits.

    It was dawn of March 21, 2018. Gary Messina was on his morning run along New York City's East River. Suddenly something caught his eye – a large 60-year-old man balancing on the four-foot-high fence that guarded the path from the water. As Messina got closer to the scene, the man took a step forward and slipped into the dark river below.

    When Messina reached nearer, the man was struggling in the water, clearly unable to swim. Other joggers also heard the man's cry. David Blauzvern and John Green dropped their phones and keys on land and jumped in. “People had called the police, but it was unclear when they'd get there.” says Green. “We just reacted.” Messina joined them in the river. Just as the jumper was losing strength, Blauzvern take hold of him. The pair were about 30 yards from the seawall when Messina and Green caught up to them. They seized the man, with Blauzvern supporting his back and Messina and Green holding him up from either side. As the men made their toward the concrete seawall that stretched (延伸) for blocks in each direction, Blauzvern had an awful realization: there was no way out of the river.

    By now, a crowd had gathered on land. “A rescue boat is on its way,” someone yelled to them. Swimming forward was getting tougher by the minute. The jumper, who was six foot two and weighed around 260 pounds, was heavy in his rescuers' arms. After ten minutes, they managed to get to the river's edge. “I've never been so out of breath,” says Blauzvern.

    Fifteen minutes after the men had jumped into the river, the two-man rescue boat appeared. But because it couldn't risk getting too close to the seawall, the men had to swim out to it. “I was completely out of energy at this point,” says Blauzvern. The men in the water pushed the jumper while the men in the boat pulled him up and, finally, to safety. The man they had saved was taken to the hospital for evaluation(评估). Details on his condition have not been known. As for the rescuers, each of them was at work by 10:30 a.m. “I was a bit late,” admits Blauzvern, smiling. “But I had a good excuse.”

    That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theater. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.

    As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away any possible robbers. Very few people were still out except a few sad-looking homeless people under blankets.

    About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.

    Suddenly I wasn't cold or tired anymore. I ran out of the door and back to where I'd heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.

    Just as I was about to give up the search, I heard the garbage truck pull up to the sidewalk next to me. When a voice called from the inside, "Alisa Camacho?" I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes. "Is this what you're looking for?" he asked, holding up a small square shape.

    It was nearly 3 a. m. by the time I got into bed. I wouldn't get much sleep that night, but I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other.

    Director James Cameron went to new depths for his film-making on Sunday by setting the world record for the deepest ocean dive by a single person.

    This type of extreme research is nothing new to the director. Cameron, 57, is most famous for directing Titanic (1997) and Avantar (2009). During the several years of research for Titanic, he famously traveled to the bottom of the ocean to visit the sunken ship. He also visited the deep sea as research for his fictional 1989 film. The Abyss, which is about a submarine that comes across an alien species. "Most people know me as a film-maker," Cameron said. "But the idea of exploring the ocean has always been the stronger drive in my life."

    Cameron and his team had been preparing for the trip for seven years. On Sunday, Cameron took more than two and a half hours to make the dangerous 6.8-mile journey down to the Trench, an area with near-freezing temperatures, no sunlight, and heavy water pressure. Cameron traveled in a 24-foot-long mini-submarine he helped design, equipped with lights and 3D cameras for filming the adventure. It also had a mechanical arm for collecting samples of soil and deep-sea creatures. Humans had not visited the Mariana Trench since two divers first reached the deep-sea spot in 1960. The divers Don Walsh and Swiss oceanographer Jacques Piccard spent 20 minutes there but could hardly see anything. They took no pictures.

    In his well-equipped submarine, Cameron was able to spend three hours in the Trench, exploring and filming. He plans to use his recordings in a 3D film production for movie theaters and for a National Geographic TV special. "I see this as the beginning," Cameron said. "It's not a one-time deal. This is just the beginning of opening up this new frontier."

    Recently, as the British doctor Robert Winston took a train from London to Manchester, he found himself having to listen to a loud conversation of a fellow passenger woman. Boiling with anger, Winston took her picture and sent it to his more than 40,000 followers on the Tweet. By the time the train reached the station in Manchester, some journalists were waiting for the woman. And when they showed her the doctor's messages, she used just one word to describe Winston's actions: rude.

    Winston's tale is a good example of increasing rudeness, fueled by social media in our age. Studies show that rudeness spreads quickly and virally, almost like the common cold. Just witnessing rudeness makes it far more likely that we, in turn, will be rude later on. Once infected, we are more aggressive, less creative and worse at our jobs. The only way out is to make a conscious decision to do so. We must have the courage to call it out, face to face. We must say, "Just stop." For Winston, that would have meant approaching the woman, telling her that her conversation was frustrating other passengers and politely asking her to speak more quietly or make the call at another time.

    The anger we feel at the rude behavior of a stranger can drive us to do out-of-place things. Research discovered that the acts of revenge (报复) people had taken ranged from the ridiculous to the disturbing. Winston did shine a spotlight on the woman's behavior—but in a way that shamed her.

    When we see rudeness occur in public places, we must step up and say something. And we can do it with grace, by handling it without a bit of aggression and without being rude ourselves. Because once rude people can see their actions through the eyes of others, they are far more likely to end the rudeness themselves. As this wave of rudeness rises, civilization needs civility (举止文明).
