The largest campaign of killing rats in history is set to poison millions of rats on the sub-Antarctic island of South Georgia. Scientists say the campaign planned for 2013 and 2014 will restore beautiful South Georgia to the position it once held as the world's most important nesting sites for seabirds.

    It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment. “If we can destroy the rats, at least 100 million birds will return to their home on South Georgia,” says Tony Martin, a biology professor at the University of Dundee who was invited to lead the project.

    South Georgia is by far the largest island to get rid of animals that destroy native wildlife after being introduced deliberately or accidentally by people. Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world.

    South Georgia is seven times the size of New Zealand's Campbell Island, currently the largest area ever killing rats. The successful war against Campbell Island rats was carried out in 2001 with 132 tons of poison dropped from five helicopters.

    “New Zealand pioneered the techniques for ridding islands of rats and in fact our operation on South Georgia is based on New Zealand's technology.” Says Martin. “Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, in the Aleutian chain of the north Pacific.”

    The second and third stages in 2013 and 2014 will involve dropping as much as 300 tons of poison from the air onto every part of the island where rats might live. It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months. “Ideally we'd do in winter but the weather makes that too risky,” Martin says.

    The ecological payback will be priceless. But Martin says, “The full benefits will take decades to arrive, because some of these birds are slow to hatch.”

    After years of research and testing, the hybrid car was developed and put on the market. It' s an interesting and exciting new improvement in today' s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car' s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as “regenerative braking”, because it generates electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

    Scythians: warriors of ancient Siberia

    This major exhibition explores the story of the Scythians — nomadic tribes and masters of mounted warfare, who flourished between 900 and 200 BC. Their encounters with the Greeks, Assyrians and Persians were written into history but for centuries all trace of their culture was lost — buried beneath the ice.

    The US teenager Thomas Cheatham had planned to study Latin during his time at Hebron High School in Texas. But when he learned that the school district was going to offer a Mandarin class, he quickly changed his mind.

    “I thought Mandarin would be more beneficial than Latin,” said Cheatham, who is now in his second year of studying the language. He speaks Mandarin to order food at Chinese restaurants and can read social media posts from his Chinese-speaking friends.

    While it's a difficult language to master, the high school junior, who plans to study computer engineering, thinks it will be important for his career. “Chinese is a good language to know, especially with China becoming a growing power,” he said.

    Many experts agree that proficiency in a language spoken by a billion people worldwide will give American students an edge in the global economy. “People are looking at China as our next economic competitor, and interest in Mandarin is growing,” said Marty Abbott, executive director of the American Council on the Teaching of Foreign Languages. “We're seeing it in all parts of the country. ”

    Abbott estimates that as many as 100, 000 students are now studying Mandarin throughout the US, in public and private schools. She said the US government has designated (指定) Mandarin as a “critical needs” language and provides professional development programs for teachers. “Our government wants to increase our language competency for national security and economic competitiveness,” Abbott said.

    At the same time, the Chinese government is spreading knowledge of the Chinese language and culture through Confucius Institutes established in many US states. For example, the Confucius Institute at the University of Texas in Dallas has been the home of a Confucius Institute for 10 years. It sponsors Confucius Classrooms at 21 local public and private schools, where tens of thousands of students are learning Mandarin.

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, 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, 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 soundrack 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 soundrack 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.

All I needed to do to earn the two dollars was to clean her house for a few hours after school. It was a beautiful house with things that were common in her neighborhood, absent in mine.

Working for her brought me a sense of pride, not only because I could immerse myself in little luxuries like movies and candy, but also because I contributed half of my earnings to my mother, ensuring they were used for necessities. I was not like the children in folktales: burdensome mouths to feed, problems so severe that they were abandoned to the forest. I had a status that doing routine chores in my house did not provide — and it earned me a slow smile and confirmations that I was adult-like, not childlike.

Little by little, I got better at cleaning her house — good enough to be given more to do. After struggling to move the piano, my limbs ached terribly. Despite wanting to decline or voice my discomfort, I feared losing my job and the independence and respect it afforded me. She began to offer me her clothes, for a price. Impressed by these worn things, which looked simply elegant to a little girl who had only two dresses to wear to school, I bought a few.

Still I had trouble summoning up (鼓起) the courage to object to the increasing demands she made. Despite feeling overwhelmed, I hesitated to voice my concerns, knowing my mother would urge me to quit. However, one day while alone in the kitchen with my father, I expressed my disappointment. In any case, he put down his cup of coffee and said, "Whatever the work is, do it well — not for the boss but for yourself. You make the job; it doesn't make you. You are not the work you do; you are the person you are."

I have worked for all sorts of people since then, geniuses and fools, quick-witted and dull, big-hearted and narrow. I've had many kinds of jobs, but since that conversation with my father, I have never considered the level of labor to be the measure of myself, and I have never placed the security of a job above my self-worth and family value.
