What makes a person a giver or a taker? The idea of “give versus take” takes shape in all relationships of our lives. We're either giving advice, making time for people, or we're on the receiving end. We alternate between the two based on different situations we face on a daily basis, it not an hourly one.

    According to Adam Grant, a professor at Pennsylvania University, most people are matchers. They make careful observations on takers and make it a point for them to pay something back. They hate to see people who act so generously towards others without receiving any reward. Actually, most matchers will try to promote and support givers so that they can get the good they deserve.

    Another professor named Hannah Rile Bowles, from Harvard University, led a study on the idea. She asked 200 senior managers to sit down in pairs where one person would act as the boss and the other as an employee to negotiate salary promotions. Male employees asked for an average salary of $146 k while the females asked for only $141 k. But why did they not bargain as hard as the men? Simply because they were more likely to be givers.

    As a woman, I do enjoy the act of giving up my time, my knowledge and my care and attention to others. I don't expect anything in return, but I do tend to pull myself away when I feel like I'm being taken for granted. I also tend to get upset when I see a loved one's continuous actions of kindness go unnoticed. So it's safe to say I'm 50% giver,35% matcher and 15% taker.

    I do know someone, however, who is 99% giver. They're devoting their time, sharing valuable insights and going out of their way for everyone who crosses their path. Although they've changed the lives of many people, they rarely see any of it returned. But the universe is slowly repaying them; they're now extremely successful, well known for what they do.

    China is known for its long history, rich culture, and cute pandas. It's also known for some of the worst air quality in the world. But the Asian country is now using a natural weapon against air pollution – trees.

    In February, China's government announced plans to cover at least 32,400 square miles with forest. That is about the size of Ireland. Some 60,000 soldiers will take charge of the tree-planting program. Most of the trees will be planted in Hebei Province. That is an area surrounding China's capital, Beijing.

    Huang Wei is an environmentalist who works for Greenpeace East Asia. She is optimistic about the plan. “Trees act as a sink to absorb carbon dioxide and other pollutants,” she said. Carbon dioxide is a gas that traps the Earth's heat. It contributes to global warming.

    Why is China's air filled with harmful chemicals? It's because the country relies on coal-fired power plants. When coal is burned, PM2.5 is produced, PM2.5 is a pollutant. It can cause shortness of breath, heart attacks, and even death.

    Just two years ago, pollution levels were so high in Beijing that schools and factories had to close. Huang hopes China's tree-planting plan will reduce the nation's suffering from air pollution.

    The Chinese government is getting help from others in its drive to make the nation greener. Stefano Boeri is an Italian architect and urban planner. He is leading an effort to plant vertical（垂直的）forests in China.

    Boeri's designs have already taken root in the city of Nanjing, China. That's where the Nanjing Green Towers are under construction. The building has two towers. Thousands of trees and hanging plants will grow on the balconies and rooftops.

    Boeri says his goal is to design buildings that help the environment and improve air quality. He also hopes to encourage a new generation of green architects.

    July 16th was a bad day for Mr. Arthur Johnson. In the morning, he set out from his home in Santa Barbara, California. It was the start of his summer holidays and he decided to visit Wends at Las Vegas, then he hoped to go fishing in Lake Mead, 40 km from Las Vegas.

    Johnson's troubles started while he was driving happily across the Mojave Desert. His car went wrong and he tried to repair it. Then, to make matters worse, his attempts to start the car used up the battery (电池) and left it useless. After Johnson had waited an hour in the hot sun, a Canadian driver, John Williams, stopped and tried to help him. When both men failed, Williams promised to telephone a workshop to ask it to send a truck to pull the car away and repair its fuel pump.

    Johnson left the keys in his car and sat in the shade of a large tree. Soon he fell asleep. While he was sleeping, a repair truck arrived from San Pedro (the nearest town) and pulled his car away. Later on, Johnson woke up and thought that somebody had stolen his car. He started to walk back towards San Pedro but a police car stopped him to find out why he was walking in the desert.

    Johnson looked like a man wanted in Los Angels for robbery, so the police detained him at San Pedro for the night. The next day, Johnson telephoned his friends in Los Angeles. They drove to San Pedro and made the police believe that Johnson was a harmless salesman, so they set him free.

    “Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.

    With her eyes shining, Tori brags, “You bet I did. Sean told me two days ago.”

    Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.

    An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic–breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.

    If we know that gossip can be harmful, then why do so many of us do it? The answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of  belonging or even superiority(优越感).

    Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do's and don'ts conveyed through gossip will never show up in any student handbook.

    The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, think about why you want to gossip and what effects your “juicy story” might have.

    When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.

    These are the findings of a 40­year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. "Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society, "said George Vaillant, the psychologist (心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."

    Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men's mental­health scores with their boyhood ­activity scores. Points were awarded for part­time jobs, housework, effort in school, and ability to deal with problems.

    The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.

    Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, "One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work."

Macquarie Island is a tiny island that's part of Australia. It's about halfway between New Zealand and Antarctica. The island's been made a world heritage area because it's so untouched, but this unique environment is under threat from some unwanted visitors.

It all started when seal hunters came to the island in the early 1800s. They brought rabbits with them as a source of food for the journey, and also on board the ships were rats and mice, which made their way onto the island too. They're being blamed for destroying the homes of marine birds, causing soil loss and ripping up plant cover, as these before-and-after photos show.

So what's being done about the problem? It starts with a team of helicopters that fly across the island carrying these giant containers. Inside them are poisoned pellets (有毒饲料) which are dropped and spread across the island. For any rabbits that survived the baiting (诱饵) , there's a plan B. This special team of dogs is being put through a final training. It'll be their job to track down any remaining rabbits. They have to also learn to behave around the island's native wildlife. The dogs could be here for years or until the task is complete. The dogs don't actually kill the rabbits. They find them, then the hunters decide to either catch the rabbits or shoot them.

But the program has received a bit of criticism. Some people argue 25 million dollars is a lot of money to be spending on wiping out rabbits and rodents (啮齿目动物), and in the process, some native birds will be killed because of the baiting. 

The reality is the problem isn't going to be solved overnight. The people running the program say that even if one pair of rabbits is left alive, the whole task will be seen as a failure, which means these guys could be here for a long time, trying to ensure that this precious island remains protected from pests.
