When the Apollo astronauts (宇航员) landed on the Moon in 1969, millions of people were rather sad. The person to blame for this was an artist named Chesley Bonestell. For many years, Bonestell had been creating beautifully detailed paintings of the Moon and planets. Viewers of his artwork were unhappy because the real Moon did not look like Bonestell's pictures of it.

    As a space artist, Bonestell tried to make his drawings look exciting and as true as the Moon is. He worked closely with astronomers and scientists to get the most up-to-date scientific information available. But in the 1940s and 1950s, no one had ever seen another planet up close. Yet Bonestell's paintings looked so real that some people thought they were photographs.

    Even though Bonestell was interested in astronomy, he did not start out as a space artist. As a young man he studied architecture — the art and science of designing and making buildings. In 1938 Bonestell became a special effects artist in Hollywood. It was here that he learned he could improve his paintings by following the methods used in the movies.

    In 1944, a popular magazine published a series of Bonestell's paintings of the planet Saturn. He drew Saturn as if it were seen by someone standing on each of the planet's moons. The results were dazzling. Within a few years, Bonestell's artwork was appearing regularly in magazines and books on astronomy and space flight.

    Many of Bonestell's artworks had been right all along. But the biggest surprise was the Moon. Someone asked Bonestell what he was thinking when he saw the first pictures from the Moon. “I thought how wrong I was!” he said. “My mountains were sharp (陡峭的), and they aren't on the Moon.”

    But he shouldn't have felt bad. No space artist had ever before taken so many people to so many faraway worlds. In the years just before the first manned space flights, Bonestell's artwork prepared people for the amazing space adventure to come.

    Digital technology-email and smart phones especially-have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses arc doubtful about remote working. Half of the workers say their boss doesn't accept it, and only 35 percent say it's tolerated.

    Skeptical bosses will likely have their doubts reinforced (加深) by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while “working” remotely, while 35 percent have done housework, and 28 percent have cooked dinner.

    It is true, however, that working at home makes people much more efficient (高效的), because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush.

    The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker.

    More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who haven't worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility (灵活性) to manage their time efficiently.

    You can't imagine how terrible I felt at that time. A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.

    I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. I didn't do either well. He later informed me that I was "not athletic".

    The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

    The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.

    Shortly after crossing the start line, my shoe laces(鞋带) became untied. So I stopped to readjust. Not the start I wanted!

    At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"

    By mile17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

    By mile 21, I was starving!

    As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.

    I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

    Determined to be myself, move forward, free of shame and worldly labels(世俗标签), I can now call myself a "marathon winner".

    Imagine you are opening your own company and want to hire a manager. You have two candidates and they are both capable and experienced, so who would you rather hire: Julia Watson or Shobha Bhattacharva? Chances are that you would prefer Watson, right? But why?

    "Easy names are evaluated as more familiar, less risky and less dangerous," Eryn Newman, a scientist at Victoria University of Wellington, New Zealand, told Scientific American. As a result, people with easier names are often assumed to be more trustworthy. This is what Newman and her teammates have found in their recent study.

    In the experiment, they picked 18 different foreign names, including difficult-to-pronounce ones like Yevgeni Dherzhinsky and easy names like Bodo Wallmeyer. They then attached each name with a statement such as "turtles are deaf" and "giraffes are the only mammals that cannot jump" and asked volunteers whether they thought the claims were true.

    The results showed that claims connected to easier names were more often ranked as believable than those attributed to difficult names, regardless of what the truth really was. In fact, previous studies have already found that our judgments about products can be affected by their names. For example, we tend to think of a food additive (添加剂) with an easier name as safer and a stock with an easier name as more lucrative (利润丰厚的)，according to Medical Daily.

    But researchers pointed out that this effect can change depending on where someone comes from. For example, a native British man may find "Yevgeni Dherzhinsky" hard to pronounce while Russian people could say it without effort. Newman hopes that this finding can make us better see our biases (偏见). It's not just unfair to people that we make judgments based on gut feelings (直觉) rather than facts, and it can sometimes have serious consequences.

    For example, we may choose to believe certain eyewitnesses in court simply because their names sound more trustworthy even if they are actually lying. Or, we may let go of qualified job candidates due to their "difficult" names.

    Now, if you could make that decision again, would you still prefer Julia Watson to Shobha Bhattacharva?

    I travel a lot, and I find out different "styles"(风格）of directions every time I ask "How can I get to the post office?"

    Foreign tourists(游客) are often confused(困惑)in Japan because most streets there don't have names; in Japan, people use landmarks(地标)in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."

    In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."

    People in Los Angeles , California, have no idea of distance on the map; they measure(度量) distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it' is about five minutes from here." You say, "Yes, but how many miles away is it ?"They don't know.

    It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."
