    As soon as a person dies, decomposition(分解) begins. And the first visitors arrive. “Within 5 to 15 minutes of death, flies or other insects begin to colonize the body.” says Rabi Musah, an organic chemist at the University at Albany.

    She says different species turn up at different stages of decomposition. “So because of that, depending upon what entomological(昆虫学的) evidence you find, you can learn something about when the person died in terms of the timing of the death.”

    Flies don't tend to stick around when disturbed by detectives. But they do leave behind eggs. The eggs are hard to tell apart by appearance alone, so specialists raise them until they hatch, a few weeks later—and they get a species ID and, with a little guesswork, a person's time of death.   But Musah has come up with a more time-saving approach: chemical analysis of the eggs. She and her team investigated that method by first harvesting flies with pig-liver traps hidden throughout New York City. They collected the trapped flies and then chemically analyzed their eggs. And it turns out each species of fly egg has a unique chemical fingerprint—enough to tell the eggs apart without raising the eggs to maturity. The study is in the journal Analytical Chemistry.

    Musah and her colleague Jennifer Rosati are now testing the method on a real case. “And once we do that we will be publishing some case studies to illustrate(阐明) that this is a method that can be used, and hopefully eventually it's something that will stand up in court, and something that could speed up detective work—or help deal with a cold case.”

(1)、Which of the following can best replace the underlined word “colonize” in paragraph 1?
A、look for B、fight over C、carry away D、gather on
(2)、How can a specialist know a person's time of death?
A、By researching the habitual nature of flies. B、By relying on the entomological evidence. C、By distinguishing the appearance of flies. D、By discovering a new detective method.
(3)、What can we infer about Musah's approach from the last paragraph?
A、Scientists have published studies about it. B、It is bound to make every cold case solved. C、It may help accelerate the detection of cases. D、It will be published in Analytical Chemistry.
(4)、Where most probably can you see this article?
A、In a science fiction. B、In a newspaper. C、In a medical paper. D、In a novel.

    Birds' feathers are some of the most strikingly variable animal characteristics that can be observed by the eyes. The patterns that we see in birds' feathers are made up of combinations of scales, bars, and spots.

    We already know why birds have colored feathers. Generally, the color of feathers may protect a bird from being noticed by the enemy in the environment, or it can make a bird more appealing to potential mates by helping them to stand out. These aspects are well known. A greater mystery has been how the patterns are created.

    Dr. Ismael Galván and his team studied the color of feathers to see what types of colors were present in birds' complex feather patterns. The study shows they mainly consist of two types of colors: melanin(黑色素), which produce a range of black, grey, brown, and orange color, and carotenoids(类胡萝卜色素), which are used to create brighter colors.

    Birds cannot produce carotenoids on their own. For feathers with bright colors, birds must consume food items that contain these paints, and the carotenoids circulate through the blood and to the feather. Melanin, on the other hand, is produced by special cells in the birds' bodies.

    The team found that about 32% if the species studied have complex color patterns, with the vast majority of these complex patterns produced by melanin rather than carotenoids. If the birds were artists, they would use carotenoids as a broad brush to produce color patches, with melanin as a detail paint brush to produce more complex designs.

    But a few birds are exceptions to this rule: Three bird families do have complex patterns without melanin.

    Doctors in hospital emergency rooms often see accidental poisonings. A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a product meant to kill insects. These are common causes of accidental poisoning.

    In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.

    Millions of people know how to give abdominal thrusts(腹部按压)to save a person choking on something trapped in the throat. The American Red Cross says a rescuer should first hit the person on the back five times between the shoulder bones. If the airway is still blocked, the Red Cross suggests pushing hard five times along the victim's abdomen. You can do these abdominal thrusts by getting directly behind a sitting or standing person.

    The Mayo Clinic health centers suggest several steps if bleeding is severe. First, if possible, remove dirt from the wound and press on it with a clean cloth or piece of clothing. In the past, people were advised to stop severe bleeding with a tourniquet(止血带). But experts now say tourniquets are dangerous because they can crush(挤压) major arteries and nerves. If a wound seems infected, let the victim rest. Physical activity can spread the infection. Treat the wound with a mixture of salt and water until medical help arrives.

    To learn more about first aid, ask a hospital or an organization like the Red Cross or the Red Crescent Society for information. Training may be offered in your area.

    If you know first aid methods, you can be calmer and more helpful in case of emergency.

    As long as people have been telling stories, crones(丑陋的老太婆)have been scaring the wits out of children. "Nags(怨妇),witches, evil stepmothers, cannibals(食人妇). It's quite dreadful," says Maria Tatar, who teaches a course on folklore and mythology at Harvard. "But old women are also powerful—they're often the ones who can work magic." In the Disney film Snow White, there's a scene in which the beautiful, charming, wicked queen turns into an old hag and poisons Snow White so she'll sleep forever. The old lady in Hansel and Gretel wants to roast children in her oven and the witch in The Little Mermaid cuts out Ariel's tongue.

    Tatar says old women villains (恶人)are especially scary because,historically, the most powerful person in a child's life was the mother. "Children do have a way of splitting the mother figure into...the evil mother—who's always making rules and regulations, policing your behavior, getting angry at you—and then the kind mother—the one who is giving and protects you, makes sure that you survive."

    Veronique Tadjo, a writer who grew up in the Ivory Coast, thinks there's a fear of female power in general. She says a common figure in African folk tales is the old witch who destroys people's souls. Still, they're not all bitter and evil hags. Elderly women in folk tales often use their knowledge and experience of the world to guide the troubled protagonist(主人公). Tadjo points to the Kenyan story Marwe In The Underworld about a girl who commits suicide by drowning herself and enters the Land of the Dead where she meets an old woman. "That old woman teaches her quite a lot of things," Tadjo says. "And also, when Marwe starts longing for the world of the living, she helps her go back to the surface with a lot of riches. And we understand that Marwe has been rewarded for her goodness." In other words: Do your chores and you'll be rewarded. The point of these ancient tales, no matter what continent they come from, may have been to scare children into behaving.

    Perhaps the scariest old woman character—the ugly Baba Yaga—comes from Russia. She's bony with a hooked nose and long, iron teeth. Her hut(小屋)stands on chicken legs and she kidnaps children and eats them. Safe to say Baba Yaga has been making Eastern European children sleepless for centuries. In one interpretation, a mean stepmother sends the young girl Vasilisa to Baba Yaga's hut in the woods to get a candle. The girl is sure she's being sent to her death. Baba Yaga forces her to cook and clean, and Vasilisa does everything she's told. In the end, the old crone gives her what she needs and sends her home. "You see this kind of double face of the hag,"Maria Tatar says. "On the one hand: aggressive, threatening. And on the other hand: sometimes to make sure that there is a happily ever after."

    There's that power again. In Japanese folklore, the Yama Uba(山姥)is an equally ambiguous old woman. She's a mountain witch who, like Baba Yaga, lures people into her hut and eats them. But she'll also help a lost traveler. Noriko Reider is a professor at Miami University of Ohio who's done extensive research on Yama Uba stories. "She brings fortune and happiness," Reider says. "She can also bring death and destruction for those who are not very good."

    According to Cuban-American writer Alma Flor Ada, in Hispanic(拉美地区的)culture old women are multi-talented. Ada is co-author of Tales Our Grandmas Told, which includes a story about Caliph's son who becomes seriously ill. After "all of the best physicians in the land" fail to cure him, Caliph sends his messengers searching for help. Then one morning, an old woman arrives with this advice: To get well, the prince must wear the overcoat of a man who is truly happy. And of course it works.

    A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors.

    The newly formed Wild Network—a collaboration of nearly 400 organizations—is attempting to attract youngsters away from television and computer screens to fields, woods and parks. Members of the network include the National Trust, RSPB, Play England and the NHS. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being.

    A documentary film, Project Wild Thing, will forecast the launch at more than 50 cinemas across the UK from Friday. It looks at the increasing link between children and nature.

    Andy Simpson, chairman of the Wild Network, said, "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is decreasing, roaming (漫步) ranges have fallen largely, activity levels are declining and the ability to identify common species has been lost."

    Suggestions on how to get more time in nature include collecting conkers (七叶树果), camping, snail racing, and observing autumn colour on trees.

    From January, the network will aim to make suggestions on how the government can do more to get children muddy and bright-eyed.

    This is not the first time the message of less screen time, more play has been brought up. Children in the 1980s were requested to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off the TV set and go to do something less boring instead".
