Danielle Steel, America's sweetheart, is one of the hardest working women in the book business. Unlike other productive authors who write one book at a time, she can work on up to five. Her research before writing takes at least three years. Once she has fully studied her subjects, ready to dive into the book, she can spend twenty hours nonstop at her desk.

    Danielle Steel comes from New York and was sent to France for her education. After graduation, she worked in the public relations and advertising industries. Later she started a job as a writer which she was best fit for. Her achievements are unbelievable: 390 million copies of books in print, nearly fifty New York Times best-selling novels, and a series of “Max and Martha” picture books for children to help them deal with the real-life problems of death, new babies and new schools. Her 1998 book about the death of her work shot to the top of the New York Times best-selling list as soon as it came out. Twenty-eight of her books had been made into films. She is listed in the Guinness Book of World Records for one of her books being the Times best-seller for 381 weeks straight.

    Not satisfied with a big house, a loving family, and a view of the Golden GateBridge, Danielle Steel considers her readers to be the most important resource and has kept in touch with them by e-mail. While she is often compared to the heroines of her own invention, her life is undoubtedly much quieter. But, if she does have anything in common with them, it is her strength of will and her inimitable (独特的) style. There is only one Danielle Steel.

    People who do not get enough vitamin A in their diet may develop night blindness. But in the developing world, a lack of vitamin A causes much more serious harm to children. The world Health Organization links the lack of vitamin A to as many as 250,000 child deaths every year.

    One excellent source of vitamin A is found in newly developed sweet potatoes with orange flesh. Orange sweet potatoes contain high levels of beta-carotene, which the body changes into vitamin A. Experts say orange sweet potatoes could help the Africans who are lacking in vitamin A. But, first, more people will need to be persuaded to eat them. Sweet potatoes need a better image in Africa. Jan Low with the International Potato Center says, “We do have an image problem with sweet potatoes. In many African countries, they are seen as a crop of the poor.”

    Ms. Low explains that sweet potatoes are mainly grown by poor women to feed their families in case another crop fails. The sweet potatoes commonly grown in Africa have white or yellow flesh. But they are low in vitamin A.

    Jan Low took part in a project to study how to market orange sweet potatoes to Africans best. She worked on an information campaign(活动) in Mozambique and Uganda. The campaign included radio messages about the nutritional(营养的) benefits of the orange sweet potato. They advertised its ability to “fight diseases, make you strong, clear you skin and make you look healthy”. In areas without radio, the campaigners spread the message through theater. The performances included singing, dancing and storytelling. And everywhere they went, the campaigners wore orange T-shirts and hats. They even drove orange cars.

    Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization. He mentions the efforts in the past to increase the popularity of other nutritious crops. He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat. People want to eat what they are familiar with. But Mr. Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa. Except for the color, the orange sweet potato is almost the same as what people already eat. Dan Gustafson says, “I think this time the campaigners will succeed, because they have made enough advertisements and the difference between the vegetable they have advertised and what people already eat is not a radical one.”

Senses That Work Together

    When we think about how our senses work, we usually imagine them operating separately: you sniff a flower, and the smell is delivered uninterrupted from nose to brain. However, it's more complex than that. Most evidence for cross-modal perception (知觉) comes from studies into sound and vision (视觉). But research that shows other senses crossing over is coming out all the time, and it seems that even sound and smell sometimes form an unlikely pairing.

    When New York researchers, Daniel Wesson and Donald Wilson, tried to find out the truth about a “mysterious” area of the brain called the olfactory tubercle (嗅结节)，they had to deal with this fact. Originally, they only intended to measure how olfactory tubercle cells in mice responded to smell. But during testing, Wesson noticed that every time he put his coffee cup down with a clunk (哐啷声)，the mouse cells jumped in activity. In fact, the olfactory tubercle is well-placed to receive both smell and sound information from the outside world. Later they found that among separate cells, most responded to a smell but a significant number were also active when a sound was made. Some cells even behaved differently when smell and sound were presented together, by increasing or decreasing their activity.

    Of course, mice aren't people, so research team has been carrying out further experiments. They pulled together a group of people and gave them various drinks to smell. Participants were asked to sniff the drinks, and then match them to appropriate musical instruments and produce the notes at different levels. The results were interesting: piano was regularly paired with fruity fragrances; strong smells sounded like the instruments that are made of metal.

    Further research found that listening to different sounds can change your perceptions. Studying taste this time, the team ordered some special toffee (太妃糖)and put together “soundscapes” corresponding to bitterness and sweetness. Participants tasted similar pieces of toffee while listening to each soundscape, and found the toffee more bitter or sweeter, depending on which soundtrack they were listening to.

    Studies like this are helping scientists correctly describe our understanding of the senses, and how the brain combines them with its advantage. The consequences are worth considering. Could we see musicians work together with chefs to produce sound-improved food and drink? Will you be ordering a coffee with a soundtrack to bring out your favorite smell? Come to think of it, that could be one thing you hope coffee shop chains don't get round to.

    The yearly Academy Awards ceremony was once a private affair. Now, because of television, it is very much a public affair. Hundreds of people gather in Hoolywood to see the Oscars presented to outstanding actors, and others involved（参与） in the motion picture industry. Millions more watch on the television.

    It all began on May 16, 1929, when 270 men and women sat down to dinner at the Hollywood Roosevelt Hotel. There was no secret about the winners. The names of the winners had been known for months. Janet Gaynor, for example had won as Best Actress. Douglas Fairbanks presented her with the famous gold statue（塑像）. The little statue was not then called Oscar. Like a new actor, Oscar was unknown. About six years later, it somehow got that renowned name. A number of explanations have been offered for its origin(由来), but nobody knows the true story for certain.

    Nowadays the result of the Oscar voting are kept secret. Only two people know the winners before the names are announced at the ceremony. The counting of votes is not done by one group of people but by different groups. Nobody except two members of an accounting company sees the final results.

    The information is not kept in open files. Winners' names are placed in closed envelopes. The accountants each carry a complete set of envelopes to the ceremony. One set is simply a spare to be used in case something happens to the other one.

    A voyaging ship was wrecked during a storm at sea and only two of the men aboard were able to swim to a small, desert-like island. Not knowing what else to do, the two survivors agreed that they had no alternative than to pray to God.

    However, to find out whose prayers were more powerful, they agreed to divide the territory between them and stay on opposite sides of the island.

    The first thing they prayed for was food. The next morning, the first man saw a fruit-bearing tree on his side of the island, and he was able to eat its fruit. But the other man's parcel of land remained barren.

    After a week, the first man became lonely and decided to pray for a wife. The next day, another ship was wrecked and the only survivor was a woman who swam to his side of the island. But on the other side of the island, there was nothing.

    Soon thereafter the first man prayed for a house, clothes and more food. The next day, like magic, all of these things were given to him. However, the second man still had nothing.

    Finally, the first man prayed for a ship so that he and his wife could leave the island, and in the morning he found a ship docked at his side of the island.

    The first man boarded the ship with his wife and decided to leave the second man on the island, considering the other man unworthy to receive God's blessings since none of his prayers had been answered.

    As the ship was about to leave, the first man heard a voice from Heaven booming, "Why are you leaving your companion on the island?"

    "My blessings are mine alone since I was the one who prayed for them," the first man answered. "His prayers were all unanswered and so he doesn't deserve anything."

    "You are mistaken!" the voice rebuked him. "He had only one prayer, which I answered. If not for that, you would not have received any of my blessings."

    "Tell me," the first man asked the voice, "what did he pray for that I should owe him anything?"

    "He prayed that all your prayers would be answered."

    For all we know, our blessings are not the fruits of our prayers alone, but those of another praying for us. So what you do for others is more important than what you do for yourself.

    Ask any new college graduate about his immediate goals, and it is likely that he will tell you he wants a job. But it turns out that today's students are not going to be satisfied with any job. According to the latest survey, making a difference through their work is essential (必要的) to young people's happiness.

    The survey found that 72 percent of graduating college seniors believe being able to have a positive social influence through their work is essential to their happiness. Making a difference is so important to them that 45 percent say they would take a 15-percent pay cut to work at an organization that has a social or environmental influence, and 58 percent say they would take a pay cut to work for an organization whose values are the same as their own.

    Besides this, the survey found that female students are far more likely to put social influence in first place than their male classmates, echoing the results of a former study showing that female maths and science majors are more likely to say they go into those fields to make a difference.

    One reason for the emphasis (强调) on improving the world probably has to do with the culture of colleges, which encourages students to connect their studies back to real-world problems. Students are used to discussing important social issues (问题) with their friends and professors, and doing something about them in class or through volunteer activities. Once students develop those habits, they don't shut them off when graduation rolls around.
