阅读理解

    If you walk through a park, you may enjoy the scents(气味)of flowers, water and soil. If you are especially lucky, you will get to smell fresh-cut grass. It's a beloved scent that transports many people back to their childhood. But there's a dark side to that smell. Indeed, we are in love with the scent of fear.

    Plants have many different chemical defenses. That smell is one of them, as the grass responds to an attack, signaling(向......示意)to the surrounding grass that danger is coming. The fresh, "green” scent of a just-mowed lawn is the lawn trying to save itself, says a story at science website Real-Clear Science.

    The smell is produced by a mix of chemicals called green leaf volatiles(GLVs, 绿叶挥发物). When the leafy plants are injured by animals eating them, people cutting them, or any other rough treatment-they give off GLVs into the air. These GLVs are a warning to neighbouring plants that their flowers might be removed, so they can move resources like sugar toward their roots and away from their flowers. This reduces a plant's potential losses and can help it grow back later.

    The rush of GLVs does a few other things, too. One chemical helps to close the wound on the damaged plant. Others act as antibiotics(抗生素)and prevent bacterial infections.

    Some GLVs may also react with animals that eat plants. Silke All-mann and Ian T.Baldwin, researchers from the University of Amsterdam, Netherlands, found that some caterpillars(毛虫)are changed by the GLV compounds(化合物)when they eat a tobacco plant. Tobacco makes the caterpillars more attractive to predators(捕食者). For the tobacco plants, this is like having an older brother come to beat up your bully(欺凌者).

    Thankfully, nothing is coming to eat you when you mow the lawn. Instead, we human get treated to some great-smelling GLVs. One is a compound known as"cis-3-hexenal". This is the same chemical that gives strawberries their sweet scent. Similar compounds are also found in apples and olives.

    "Just about all fresh vegetables have some GLV scents to them," Baldwin told Live Science, and fruits may release the compounds as they soften." Throughout evolutionary history, we've used that information to know when something is ripe," Baldwin said. Now we can use it to know when grass is frightened.

(1)、What do we know about GLVs?
A、They are harmful to humans. B、They are unique to flowering plants. C、They tend to stay in the air for a long time.      D、They are released when plants get hurt.
(2)、How may plants react to the GLVs produced by neighbouring plants?

(3)、In paragraph5,the underlined part "an older brother" refers to
A、a kind of antibiotic B、a predator.      C、a caterpillar. D、a tobacco plant.
(4)、According to Baldwin, GLVs can
A、tell us whether fruits are ready to eat. B、protect plants from pests. C、help fruits grow more quickly. D、help people choose delicious fruits.

    Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took days, weeks and sometimes months for people to receive news. Now it is possible to send words and pictures around the world in seconds. Billions of people learn about news stories of their own country and all over the world every day, either by watching TV or reading newspapers.

    Newspapers have been an important part of everyday life since the 18th century. Many countries have hundreds of different newspapers. How do newspaper editors decide which news stories to print? Why do they print some stories and not others? What makes a good newspaper story?

    Firstly, it is important to report new stories. TV stations can report news much faster than newspapers. Yet, newspapers give more about the same story. They may also look at the story in another way, or they may print completely different stories to those on TV.

    Secondly, a news story has to be interesting and unusual. People don't want to read stories about everyday life as a result, many stories are about some kind of danger and seem to be "bad" news. For example, newspapers never print stories about planes landing safely, instead they print stories about plane accidents.

    Another factor (因素) is also very important in many news stories. Many people are interested in news in foreign countries, but more prefer to read stories about people, places and events in their own country. So the stories on the front page in Chinese newspapers are usually very different from the ones in British, French and American newspapers.

    Beverly Cleary has sold 85 million copies of 41 books and — if those numbers weren't impressive enough — she turns 100 on Tuesday. Though the world was a very different place when Cleary was a child, she has always maintained that kids pretty much stay the same — which explains the ongoing popularity of her beloved characters, like Ramona Quimby, Henry Huggins and Ralph S. Mouse.

    Cleary was in her early 30s and working part time in a bookstore when she sat down at a typewriter to see if just maybe she could write a book for kids. She had worked as a librarian before World War II, and she wished she'd had books for young readers about children living everyday lives.

    "I think children want to read about normal, everyday kids," she told NPR in 1999. "That's what I wanted to read about when I was growing up. I wanted to read about the sort of boys and girls that I knew in my neighborhood and in my school. ... I think children like to find themselves in books."

    Her first book, Henry Huggins, came out in 1950. Henry had a friend named Beezus, and Beezus had a mischievous(爱恶作剧的) but lovable little sister named Ramona. Over the next five decades, Cleary took Ramona all the way from nursery school (托儿所)to the fourth grade. Cleary says when she was writing Ramona, she took inspiration(灵感) from a little girl who lived in the house behind her as a child.

    Her books have hooked generations(几代) of children, including a young Jeff Kinney, who grew up to become the author of the "Diary of a Wimpy Kid" series.

    "I must have been about 8 or 9 years old when I first read Beverly Cleary," Kinney recalls. "The book that really grabbed me was Ramona Quimby, Age 8. She looked feral. I needed to get to know this character."

    "Most kids have parents, teachers, bullies(欺凌) — we all experience these things,"Kinney says. "And Beverly Cleary tapped into that. Her work is still as relevant today as when it first came out."

    Now, generations of children have been fortunate enough to enjoy her stories of Klickitat Street.

    Jealousy is such a powerful emotion that at least one study has characterized it as the third leading cause of non-accidental homicide(杀人) in all cultures. In a recently published study, researchers experimented with dogs to see whether they, like humans, have the nature of jealousy.

In an experiment, the authors took 36 dogs—along with their owners—and observed the dogs' behavior as their masters interacted with three non-living objects. One object was a children's book, which they read aloud; another object was a plastic pumpkin lantern; and the third was a mechanical stuffed dog that gave out a bark when the owner pressed a button.

    Former studies concluded that babies were probably capable of jealousy. In the experiment, their mothers showed attention to a life-like doll instead of their child, and other objects. The babies were reportedly more likely to respond with “negative” behavior if their mother turned to pay her attention to the doll.

    In the dog experiment, authors instructed the dog owners to push the bark button on the stuffed dog's head, and then speak to it sweetly, while ignoring their own dog. After that, they showed attention to the pumpkin lantern, and read the children's book, while also ignoring their dog.

    It is interesting to see the dogs were far more likely to act aggressively when their owners spoke to the stuffed dog than when they paid attention to the other objects. One-fourth of the dogs snapped at the stuffed dog, while only one dog snapped at the lantern or the book. The dogs were also more likely to push or touch their owners as they interacted with the mechanical dogs, and tried to get in between the owner and the stuffed dog more frequently than the other objects.

    “One possibility is that jealousy developed in species of many young relying on the parents, the young compete for parental resources such as food, attention, care, and affection,” the authors wrote.

    As computers become more popular in China, Chinese people are increasingly depending on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their assignment and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, "Chinese characters enjoy both practical and aesthetic value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to turn in their homework and essays written by hand.
