In the frozen continent of Antarctica scientists fear an alien invasion — not from outer space, but carried in people's pockets and bags.

    Seeds and plants accidentally brought to Antarctica by tourists and scientists may introduce alien plant species which could threaten the survival of native plants in the finely balanced ecosystem.

    “The people that were carrying the most had lots and lots of seeds. They really were real threats,” said Dana Bergstrom, from the Australian Antarctic Division.

    “When we take things in through hitchhiking（搭车旅行） then we get species which are competitive. The plants and animals there are not necessarily competitive, so we'd start losing various precious biodiversity（生物多样性） on the (Antarctic) continent”, Bergstrom told Reuters.

    Amongst the alien species discovered were the Iceland Poppy, and Annual Winter Grass — all from cold climates and capable of growing in Antarctica.

    The Antarctic Peninsula, where most tourists travel, is now considered a “hot spot” on the frozen continent and the warmer the climate, the easier for seeds to grow. “The peninsula(半岛) is warming at some of the greatest rates on the planet,” said Bergstrom.

    The study, the first continent-wide assessment of invasive species in Antarctica, surveyed about 1,000 passengers during 2007-2008, the first year of the International Polar Year, an international effort to research the polar areas.

    Bergstrom said the one alien seed that had gained a foothold is Annual Winter Grass. It is a strong weed in the sub-Antarctic and is on the Antarctic island of King George. It has also made its way to the tail part of the Antarctic continent.

    Many parents have learned the hard way that what sounds like open communication is often the very thing that closes a youngster's ears and mouth. One common mistake is the Lecture, the long monologue that often starts with “When I was your age” Eighteen-year-old Kelly calls lectures “long, one-side discussions in which I don't say much.”

    Kids reflexively(条件反射地)shut down in the face of a lecture. Their eyes glaze over(呆滞),and they don't register any incoming information. Listen to 13-year-old Sarah describe her least favorite times with her mom and dad. “First, they scream. Then comes the ‘We're so disappointed' speech. Then the ‘I never did that to my parents' lecture begins. After that, even if they realize how ridiculous they sound they never take it back.”

    Lines like “When you have children of your own, you'll understand” have been seriously said by parents since time immemorial. But many of our expert parents, like Bobby, a registered nurse and mother of three, feel that by falling back on clichés(陈词滥调)to justify your actions, we weaken our position.

    Since kids are creatures of here and now, the far-off future has no relevance to them. Therefore, good communicators like Bobby suggest, “Give specific reasons for your actions in present language: ‘I'm not letting you go to the party because I don't think there will be enough adult supervisions.'”

    Betty, who lives in Missouri, uses an indirect approach. “I find that warnings are accepted more readily if I discuss a news article on a subject I am concerned about. My husband and I talk about it while our children absorb the information. Then they never think I'm preaching(布道).”

This really helped when Betty's kids began driving. Instead of constantly repeating “Don't drink; don't speed,” she would talk about articles in the paper and express sympathy for the victims of a car crash. Betty made no special effort to draw her kids into the conversation. She depended on a teenager's strong desire to put in his opinions—especially if he thinks he isn't being asked for them.

    The European Parliament has approved a law banning a wide-range of single-use plastic items, such as straws and cotton buds by 2021. "Europe is setting new standards, paving the way(铺路) for the rest of the world," the European Commission's vice-president Frans Timmermans, who is responsible for sustainable development, said in a statement.

    The new plans come after the EC found that plastics make up more than 80% of marine litter, which has disastrous effects on wildlife and habitats. The EU parliament notes that because of its slow rate of breaking down, plastic residue(残余) has been found in marine species as well as fish and shellfish - and therefore also makes its way into the human food chain.

    Under the new European law, tobacco companies will be required to cover the costs for the collection of cigarette butts. Manufacturers of fishing tools will also have to pay for the retrieval(找回) of any plastic nets that have been left at sea. There's also a new focus on further raising public awareness, where producers of items such as tobacco filters(滤嘴), plastic cups, and wet wipes will be required to clearly explain to users how to appropriately dispose of them.

    The European Commission first suggested the ban in May, which was approved by member states in October. China last year banned the import of 24 varieties of solid waste, including types of plastic and unsorted paper, putting pressure on Europe to deal with its own waste.

    The World Economic Forum estimates that there are about 150 million tons of plastic in the world's seas. A study published in Science in 2015 suggested that between 5 and 13 million tons more are flowing into them every year. Research shows there will be more plastic than fish by weight in the world's oceans by 2050, which has encouraged policymakers, individuals and companies into action.

Half a Day

    I walked alongside my father, holding his right hand. All my clothes were new: the black shoes, the green school uniform, and the red cap. They did not make me happy, however, as this was the day I was to be thrown into school for the first time.

    "Why school?" I asked my father. "What have I done?"

    "I'm not punishing you," he said, laughing. "School's not a punishment. It's a place that makes useful men out of boys. Don't you want to be useful like your brothers?"

    I was not convinced. I did not believe there was really any good to be had in tearing me away from my home and throwing me into the huge, high-walled building.

    When we arrived at the gate we could see the courtyard, vast and full of boys and girls. "Go in by you," said my father, "and join them. Put a smile on your face and be a good example to others."

    I hesitated and squeezed his hand firmly, but he gently pushed me from him. "Be a man", he said. "Today you truly begin life. You will find me waiting for you when it's time to leave."

    I took a few steps. Then the faces of the boys and girls came into view. I did not know a single one of them, and none of them knew me. I felt I was a stranger who had lost his way. But then some boys began to glance at me in curiosity, and one of them came over and asked, "Who brought you?"

    "My father," I whispered.

    "My father's dead," he said simply.

    I did not know what to say. The gate was now closed. Some of the children burst into tears. The bell rang. A lady came along and said, "This is your new home. There are mothers and fathers here, too. Everything that is enjoyable and beneficial is here. So dry your tears and face life joyfully."

    Well, it seemed that my misgivings had had no basis. From the first moments I made many friends. I had never imagined school would have this rich variety of experiences.

    This year marks the 170th anniversary of Paul Gauguin's birth. He lived for just 54 years but he packed his brief life with activity.

    The French painter spent his early childhood in Peru before returning to France. As an adult, he continued to travel a lot. Most famously, he spent much of the last decade of his life in Tahiti, an island in southern Pacific Ocean. Indeed, Gauguin is best known for his colorful paintings of Tahitians and their culture.

    The restlessness of this great painter has been normal among modern artists since the middle of the 19th century. They're never satisfied for long with a certain style or way of life. Once something becomes conventional, it's turned down.

    The artistic culture that Gauguin developed from was that of Impressionism (印象派). Painters like Claude Monet had wanted to paint how they saw the world, not how their teachers taught them it should be seen. Gauguin, and similar artists like his friend Vincent van Gogh, moved even further away from "respectable" art than the Impressionists. For them, it was not simply a matter of seeing the world differently, but feeling and thinking about it differently, too.

    Gauguin saw, felt and thought differently from most members of European society. He thought that European culture was too fancy and not spontaneous. This is why he turned to the traditions of other parts of the world, like Africa, and, eventually, Tahiti. Artists like Gauguin used the word "primitive" for these cultures, but not as a negative term. For him, Europe, in becoming modem, industrial and scientific, seemed less natural than other parts of the world.

    In truth, Gauguin's paintings may be unconventional but they are certainly not "primitive". They are the work of a painter with great awareness of what he was doing. It was this awareness that made him such an important painter for those that came after, in the 20th century. When we look closely at the works of Gauguin we begin to understand Pablo Picasso, and especially Henri Matisse, a little better.
