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 _ . 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 , 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. Question: Bonestell made his space drawings _ . Options: A: from a very early age B: by copying photographs C: with the help of scientists D: in order to make a living

A new study suggests that listening to music in the office improves the speed and accuracy of tasks such as data entry,proof reading and problem solving. In an office-based experiment,88 pet cent of participants were found to produce their most accurate work when listening to music. The study also found that 81 per cent completed their fastest work when music was played. And it matters what type of music you listen to.For instance,if you're doing your tax returns,then classical music is the most effective as it improves maths skills. Listening to Jessie J or Justin Bieber could also improve your speed,with 58 per cent of participants completing data entry tasks faster while listening to pop songs. During proof-reading,dance music,such as David Guetta,had the biggest positive impact with participants increasing their speed by 20 per cent compared to tests undertaken with no music at a11. Dance music also had a positive effect on spell-checking with a 75 per cent pass rate compared to 68 percent when no music was played al a11. The research,undertaken by Brighton-based Mindlab International,suggests that silent offices may be the least productive. "The music experiment showed that when listening to music,nine out of 10 people performed better,"said Dr.David Lewis.Chairman of Mindlab International. "Proper music enables people to quickly process and keep information,regulate their behaviors,make good choices,solve problems,plan and adjust to changing mental demands,"a senior investigator of Mindlab International explains. "While many schools are cutting music programs and spending more and more time on test preparation,our findings suggest that musical training may actually help to set up children for a better academic future."added D r.David Lewis. Question: According to the passage,we can conclude that _ . Options: A: different kinds of music lead to the same effect B: silent offices can make people perform better C: listening to proper music can improve efficiency in office D: more tests prepare children for a better academic future

The envelope was addressed to a man named Raoul, who, I was ly certain, did not live with us. The envelope wasn't sealed, so I opened it. The inside of the card was blank. Ed, my husband, explained that the card was both from and to the newspaper deliveryman. His name was apparently Raoul, and Raoul wanted a holiday tip. We were meant to put a check inside the card and then drop the envelope in the mail. When your services are finished at 4 a.m., you can't simply hang around, like a hotel bellboy expecting a tip. You have to be direct. So I wrote a nice holiday greeting to this man who, in my imagination, fires The New York Times from his bike aimed at our front door, causing more noise with mere newsprint than most people manage with sophisticated black market fireworks. With a start, I realized that perhaps the reason for the 4 a.m. wake-up noise was not ordinary rudeness but carefully executed spite : I had not tipped Raoul in Christmas past. I honestly hadn't realized I was supposed to. This was the first time he'd used the card tactic . So I got out my checkbook. Somewhere along the line, holiday tipping went from an optional thank-you for a year of services to a Mafia-style protection racket . Several days later, I was bringing our garbage bins back when I noticed an envelope taped to one of the lids. The outside of the envelope said MICKEY. It had to be another tip request, this time from our garbage collector. Unlike Raoul, Mickey hadn't enclosed his own Christmas card from me. In a way, I appreciated the directness. "I know you don't care how merry my Christmas is, and that's fine," the gesture said. "I want $30, or I'll 'forget' to empty your garbage bin some hot summer day." I put a check in the envelope and taped it back to the bin. The next morning, Ed noticed that the envelope was gone, though the trash hadn't yet been picked up: "Someone stole Mickey's tip!" Ed was quite certain. He made me call the bank and cancel... Question: The newspaper deliveryman put a blank card inside the envelope because _ . Options: A: he wanted the couple to pay for the newspaper B: he forgot to write a few words on it C: he used it to ask for a Christmas tip D: he was afraid of asking for a tip in person
