    Hacking isn't just for computers and smartphones, According to a study published last week in the journal Science, scientists have found a way to hack a plant's genes in order to make it use sunlight more quickly. Someday, the results could increase the amount of food produced around the world.

    Photosynthesis(光合作用)is the word used to describe how plants use sunlight, water, and carbon dioxide to make their own food. Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant's genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent.

    "Specifically, scientists hacked the plant's protective system. Normally, this system is activated when a plant gets too much sunlight, "said scientist Krishna Niyogi, co-author of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow.

    Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses. When a person wears the glasses outside during the day, the lenses(镜片)darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.

    The new study sped up the process. By changing the plant's genes, the protective system turned on and off more quickly than normal. As a result, leaf growth on the plants scientists used in the study increased. Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice.

(1)、What will happen to the plants when scientists change plants' genes?
A、They will become weaker and weaker. B、They will grow fast to produce more food. C、They will have more beautiful flowers. D、They will depend less on sunlight.
(2)、Why does the author mention light-adjusting glasses?
A、To warn people of the hot and bright sun. B、To explain the principle of plants' protective system. C、To help leaves of the plants absorb sunlight. D、To serve the science experiment smoothly.
(3)、In the future, the genetic changes will be used to.
A、improve tobacco plants' quality B、increase tobacco plants' leaves and roots C、improve the flowers' living time D、increase the production of corn and rice
(4)、Which of the following can be the theme of this text?
A、Hacking plants for more production B、Leaf growing more quickly C、Double production of tobacco plants D、Photosynthesis and production

    Nothing could stop Dad. After he was put on disability for a bad back, he bought a small farm in the country, just enough to grow food for the family. He planted vegetables, fruit trees and even kept bees for honey.

    And every week he cleaned Old Man McColgin's chicken house in exchange for manure(肥料). The smell really burned the inside of your nose. When we complained about the terrible smell, Dad said the stronger the manure, the healthier the crops, and he was right. For example, just one of his cantaloupes filled the entire house with its sweet smell, and the taste was even sweeter.

    As the vegetables started coming in, Dad threw himself into cooking. One day, armed with a basket of vegetables, he announced he was going to make stew(炖菜).Dad pulled out a pressure cooker and filled it up with cabbages, eggplants, potatoes, corns, onions and carrots. For about half an hour, the pressure built and the vegetables cooked. Finally, Dad turned off the stove, the pot began to cool and the pressure relief valve sprayed out a cloud of steam. If we thought Dad's pile of chicken manure was bad, this was 10 times worse. When Dad took off the lid, the smell nearly knocked us out.

    Dad carried the pot out and we opened doors and windows to air out the house. Just how bad was it? The neighbors came out of their houses to see if we had a gas leak!

    Determined, Dad filled our plates with steaming stew and passed them around. It didn't look that bad, and after the first wave had shut down my ability to smell, it didn't offend the nose so much, either. I took a taste. It would never win a prize in a cooking competition, but it was surprisingly edible, and we drank up every last drop of soup!

    Each year, we are exposed to ten thousand ads on average. They try to sell us their products by using beautiful art, videos, images or slogans that are catchy. The most famous companies have highly popular logos that can be recognized by almost everybody. For those of you who have seen the movie Finding Forrester, there is that scene where Jamal walks up to some guy with a BMW and asks him what the car logo means. The man did not know the answer and since that day, whenever I see a famous company logo I try to find the meaning of it.

    Many think the horse on the Ferrari logo represents the horsepower of the cars they manufacture. The story behind it is far more interesting. During World War I, a pilot, Count Francesco Baracca, painted the horse on his airplane to bring him luck. He had it on his plane because it was the logo of his squadron(空军中队). Baracca's mother then convinced Enzo Ferrari to put the logo on his racing cars in the early 1930's to bring good luck to the drivers. The logo then stayed the same ever since. The yellow on the background represents the birthplace of Enzo Ferrari.

    Starbucks started in 1971, in Seattle. The mermaid(美人鱼)represented on the logo is now known by any coffee drinker. It is a mythological sea creature with the look of a female, the only difference being that they have a tail of a fish. The reason why Starbucks incorporated one in their company logo is that it was believed that mermaids used to sing to sailors in order to make them walk away from their ship or to ground their ships. In the 1500s, spices, tea and coffee were popular merchandise to trade. So the mermaid in the logo of Starbucks is the one that "brings" coffee and tea to the stores.

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to “watch” TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. “The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves."

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. “This is done in real time, in less than a second, " Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.

    Despite the celebrations, though, in the U. S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.

    It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    "Jazz seems like it's not really a part of the American appetite, "Moran tells National Public Radio's reporter Neal Conan. "What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital. "

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. "The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same, "says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, "just to kind of put it back in the mind that Waller is dance music as much as it is concert music," says Moran. "For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context," says Moran, "so I want to continue those dialogues. Those are the things I want to foster. "

Upon my arrival at Falconwood Apiary, Kaat Kaye is already engrossed in the meticulous inspection of the apian domiciles, oblivious to my arrival. I find myself privy to her soft murmurings directed towards the bees, their mellifluous drone resonating through the atmosphere, interspersed with her gentle words of encouragement and compromise.

Kaye was born with profound auditory impairment. Although she has the capacity to perceive sounds with the aid of auditory prosthetics, she often dispenses with them during her labors. "Acoustic sensations are alien to my experience," she elucidates. "I revel in the tranquility and stillness. In the company of bees, aural perception is superfluous. My concentration is heightened when not beset by incessant auditory distractions."

Adorned with naught but her cowl, apiarian instrument, and device for the emission of smoke, Kaye proceeds with a measured and deliberate gait. In contrast, I am excessively attired, having donned a comprehensive protective garment for our encounter. She advises me to shed the gloves I've brought along and directs me to a position that will minimize the agitation of the bees. Kaye's tender and cautious methodology instills a sense of calm in my presence among her charges. As our time together accrues, my admiration for Kaye's fervor for apiculture and the manner in which her auditory limitations have sculpted her distinctive methodology deepens.

In her vocation, she champions organic apicultural practices that minimize the utilization of chemical treatments. Moreover, she gathers all the requisite intelligence for the stewardship of the hives by depending on her non-auditory senses. Perhaps most notably, what renders Kaye an extraordinary apiarist is almost metaphysical. Excelling in her vocation is inextricably linked to adaptability, navigating the myriad uncertainties that emerge on any given day. Is precipitation excessive? Scarce? When will the flora reach full bloom? Will it yield a bountiful harvest of honey? She responds with alacrity, ensuring not to disrupt the bees' cadence and equilibrium.

"There is a profound, almost spiritual dimension to the craft of beekeeping," she remarked. "You cannot exert absolute dominion over them, akin to any element of the natural world, indeed. Some years bestow upon us an abundant honey harvest. Other years are fraught with adversity, resulting in the loss of half of the hive. There is considerable sorrow but also considerable delight, too, in simply toiling in the great outdoors with these sentient beings—a living, complex superorganism."
