In a Station of the Metro

    The apparition of these faces in the crowd;Petals on a wet, black bough.

    This is the only Ezra Pound poem that many people will read in their lives. Why? One obvious reason is that it's just two lines long. The poem, which can be understood as “A man sees a bunch of faces in the subway and thinks they look like flowers on a tree branch,” is an exercise in shortness. Pound wrote it after having a spiritual experience in a Paris metro (subway) station.

    In 1916, the US poet originally thought he could best describe his vision in a painting. Unfortunately, he wasn't a painter. So he wrote a thirty-line poem, which he didn't like. He dropped the long version in the waste bin. Six months later, he wrote a shorter poem, but didn't like that one either. Finally, a full year after the experience, he had been reading short Japanese poems called haikus, and he figured he would try this style. The result, which was published in 1913, is one of the most famous and influential works in modern poetry.

    This poem is one of the monuments (纪念物) of the 20th-century artistic movement known as “Imagism”. Basically, Pound and his friends thought that images (意象) weren't just decoration: they were the highest form of speech. By finding the right image, the poet can express the true, spiritual reality of a thing, which is more important than using a bunch of adjectives to describe its physical appearance. Thus, “In a Station of the Metro” is a poem that consists of one image expressed with absolute (绝对的) exactness and nothing else.

    To the imagists, the best way to describe an experience is not to use more and more words; the best way is to find exactly the right words. Have you ever told a beloved one that “words can't express” how much you love them? Well, Pound would say that you're just being lazy. In his view, words can express anything, even if it takes an entire year to find the right ones.

    Six volunteers are about to find out what it would be like to live on Mars without ever leaving the Earth. Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii. They are part of an experiment that is designed to mimic（模仿）life on Mars. Their mission began on October 15, 2014. NASA says it could send astronauts to Mars as early as the 2030s. The mission would take more than two years, so NASA needs to know how people would react to living in a small group, isolated from the rest of the world, for such a long time. Some people may become depressed or bored living under those conditions. By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission, and how to help them get along.

    They will live in a two-story building. The ground floor is about 86 square meters, roughly the size of a small two-bedroom apartment. It includes shared areas like kitchen, dining room, bathroom, laboratory and an exercise room. The upstairs is less than half the size of the downstairs. It contains another bathroom and six small bedrooms. The building is located in an abandoned quarry（采石场）about 2,400 meters up the side of Mauna Loa, the second biggest volcano in the world. It is constantly monitored for signs of volcanic activity. NASA chose the location because the appearance looks very similar to Mars.

    To make it more like being on Mars in the future, they are only able to communicate by email during the experiment. Meanwhile, there will be a 20-minute delay between the time when a message is sent and that when it is received. When they go outside, they will have to suit up in full spacesuits, just as if they were on Mars.

    The commander is Martha Lenio, a 34-year-old Canadian. During the mission, she will run experiments on growing food. The other members have backgrounds in physics and so on. None of them are astronauts.

    If you need to spend time on the road，it's important to find ways to keep safe on your feet．Don't suppose it's your right of way. Yes，you might be crossing at the right place，at the right time，within the crosswalk area，but you are still exposed to danger. It could be a distracted driver，or a cyclist with a loose sense of traffic rules，so you could still get hurt．You can be in the right legally，but that won't be much help when you're in the hospital.

    Follow pedestrian(行人) signals. Just as drivers aren't supposed to speed up to beat a light when crossing through an intersection，pedestrians need to take the same care when obeying their own signals．If the hand is flashing and the countdown is into single digits (数字), stay where you are．Trying to outrun the flashing hand is unsafe，especially as cars try to clear the intersection before the light turns red．

    Give drivers enough time to stop when crossing. Don't suppose that drivers will jam on their brakes when you hit the crosswalk signals. Some provinces，such as Alberta, issue （发出）a ticket if you don't give drivers enough time to brake.

    Cross quickly. Once you've followed all of the other rules，and it is safe to cross the street，don't then just wander along in front of six lanes (车道) of traffic. There's no need to run or jog，but respect the drivers who respected you enough to stop for you.

    In the fight to conserve tropical rainforests, here's a tool you don't often hear about orange peels. Specifically, 12,000 tons of them, dumped (倾倒) on the land. “You don't usually associate waste treatment with biodiversity benefits, something that's good for the environment.

    Tim Treuer is an ecologist at Princeton University, and he's talking about a unique conservation story. It started in the early 1990s, when an orange juice producer called Del Oro set up a company near the Guanacaste Conservation Area in Costa Rica, a region that contains several national parks and a wildlife protection zone.

    Del Oro needed somewhere to dump the orange peels, and the company also owned forested land next to the parkland that it had no intention of growing crops on. So a deal was struck: if Del Oro donated its forested land, it could dump orange peel waste on degraded(退化的) land within the conservation area. Then a thousand dump trucks' worth of orange peels were lying on the land in 1998. “And within about six months the orange peels had been turned from orange peels into this thick black rich soil.”

    “I couldn't even find the site the first time I saw it.” He couldn't find it because, over 16 years, the orange peel waste had sent the land on a journey to become a vine-choked jungle, with three times the diversity of tree species of the neighboring control plot, richer soil and a much thicker covering. In other words, the experiment was a success. The results appear in the journal Restoration Ecology.

    Treuer says perhaps this lesson could be applied elsewhere. “It's a shame that we live in a world with nutrient-limited degraded ecosystems and also nutrient-rich waste streams. We'd like to see those things come together a little bit. That's not license for any agricultural company to just start dumping their waste products on protected areas, but it does mean that land managers, people involved with industrial-scale agricultural operations should start thinking about ways to do thoughtful experimentation to see if in their particular system they can have similar win-win-win results.”

    "Hey, Bruno! Great to see you again, man!" Zeca shouted. "Come over here and meet the boys." But before Bruno could move he was frisked by two guards. He cringed as the men searched his body for hidden guns, knives or other weapons.

    "He's clean, boss," one of the men shouted out.

    Zeca introduced all the members of his gang, including the man who worked inside the printer's who was going to steal the exams. He then explained all the details of the plan. It seemed foolproof and nothing could go wrong.

    They all shook hands and quickly left.

    Bruno's heart was beating fast. He was anxious to get away from the gang and phone Clara. He raced down the hill. Then he stopped at the bottom and looked behind him. It was clear, no one was following him. He took out his phone and called Clara.

    "Hey, Clara. Listen." He was out of breath, panting heavily. "Everything went according to plan. To my plan, of course, not Zeca's!" he added, laughing excitedly.

……

    "This is amazing!" the police officer said, smiling broadly, as he looked at Bruno and Clara, who were sitting in front of him at the police station. "Well done! How did you manage to come up with such a brilliant idea?"

    "Thanks. I guess it was kind of clever." Bruno answered, acknowledging the compliment with a polite smile. He felt slightly embarrassed. "Believe it or not, the idea just popped into my head while I was taking a shower. I remembered I saw an advert once on the Internet for special spy-camera sunglasses. They have a tiny, hidden, built-in video recorder. Here they're only used by detectives and law enforcement agencies, but anybody can buy them on the Internet."

    When Bruno talked to Clara before his meeting with Zeca's gang, they both agreed it would be wrong to steal the exams, and help Zeca sell them to other people. But Bruno had worked out an ingenious plan to dounle-cross Zeca and stay out of trouble himself.

    First of all, he had wisely agreed to go along with Zeca's plan, and go to the meeting with the gang of thieves. When he arrived at the hideout, they frisked him for hidden weapons, but no one ever imagined that Bruno was wearing sunglasses with a tiny built-in camera. Bruno had secretly videoed the entire meeting, making sure he had taken close-up shots of all the gang members. Their conversations with all the details of their plan had also been recorded.

    Then, as soon as he was sure that he wasn't being followed, he phoned Clara and together they went to the police with the camera and told them the whole story.

    "Thanks to this evidence we can finally catch Zeca and his entire gang red-handed," the police officer continued. "But we need you and Clara to help us. It's very important that you both continue to act as if nothing has happened. You must play along with whatever Zeca wants. We'll be following your every move from now on. Just do everything Zeca tells you to, OK?"

    The police then went to the printer's and spoke to the owner. He agreed to co-operate and they installed some hidden cameras there, too. The day of the theft they saw the thief copy the exam papers on Closed Circuit Television(闭路电视), but they did not arrest him yet.

    Then they waited until Zeca made the next move.

    In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip(点滴)above her to fight her bone cancer. Over her bald(秃的)head, she wore a pink hat that matched her clothes. But the third grader's cheery dressing didn't mask her pain and weary eyes.

    Then a visitor showed up. "Do you want to write a song?" asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. "Have you ever written a poem?" Anita Kruse continued. "Well, yes," Simran said.

    Within minutes, Simran was reading her poem into the microphone. "Some bird soaring through the sky," she said softly. "Imagination in its head…" Anita Kruse added piano music, a few warbling (鸣,唱)birds, and finally the girl's voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.

    That was the beginning of Anita Kruse's project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help "came in one flash".

    The effect on the kids has been great. One teenage girl, curling(蜷缩)in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin's disease who rarely spoke surprised his doctors with a song he called I Can Make It.

    "My time with the kids is heartbreaking because of the severity of their illnesses," says Anita Kruse. "But they also make you happy, when the children are smiling, excited to share their CD with their families."

    Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the "really sweet and nice and loving" lady who gave them a shining moment in the dark hour.
