It has been found that plastic that finds itself into UK's waters can find its way to the Arctic within just two years. UK researchers have used a current-tracking tool to follow the waste as it was carried by the waters of the northern hemisphere.

    The team at Imperial College London used PlasticAdrift.org to track ocean currents(洋流) and follow the trail of plastic north to the freezing Arctic waters. Their study revealed that the majority of plastic waste which didn't end up on the UK's coastline, or sink to the ocean floor, was carried through the Barents Sea, north of Norway, before being carried into the Arctic Ocean.

    Large pockets of the world's oceans are now choked with a soup of discarded plastics, made up of everything from shopping bags to old children's toys, brought to these trash “islands” by the currents. Over time larger chunks (厚块，大块) are broken down by the sun's ultraviolet rays (紫外线) and the saltwater, leaving plenty of micro plastics which can kill fish and other wildlife.

    Dr. Erik Van Sebille, a lecturer in oceanography (海洋学) and climate change at Imperial, said, “We're only just beginning to understand the effect that plastic waste has on the weak Arctic ecosystem(生态系统), but we know enough about the damage done by oceanic plastic pollution to act and reduce its impact on our oceans and coastlines. From seabirds caught in loops of plastic packaging to polystyrene particles(聚苯乙烯粒子) blocking the digestive(消化的) systems of fish, plastic causes a continuous path of destruction from surface to seafloor. This analysis shows how in the UK we're part of the problem.”

    Dr. Erik continued, “It would be impossible to ban plastic, and undesirable as it is, it's a useful material that offers many benefits. We should instead have a holistic (整体的) approach to improving the situation, including social and behavioral, chemical and engineering solutions. Our aim is to have the least amount of plastic that ends up in the oceans and make sure it degrades (降解) quickly and safely if it does. ”

    Mrs Smith trembled(颤抖)with excitement when she was told her fortunes(命运). "Somebody is coming home to you, " Mrs Gray said slowly. "He's carrying a rifle(步枪)on his back and he's almost there."

    Mrs Smith felt as if she could hardly breathe. "And there he is!"Mrs Gray cried, pointing to the road. They all rushed to the door to look.

    A man in a blue coat, with a gun on his back, was walking down the road toward the Smith farm. His face was hidden by a large pack on his back.

    Laughing and crying, Mrs Smith grabbed(抓住)her hat and her children and ran out of Mrs Gray's house. She hurried down the road after him, calling his name and pulling her children along with her. But the soldier was too far away for her voice to reach him.

    When she got back to their farm, she saw the man standing by the fence. He was looking at the little house and the field of yellow wheat. The sun was almost touching the hills in the west. The cowbells rang softly as the animals moved toward the barn(畜棚).

    "How peaceful it all is, "Private Smith thought." How far away from the battles, the hospitals, the wounded and the dead. My little farm in Wisconsin. How could I have left it for those years of killing and suffering?"

    Mrs Smith hurried up to her husband. Her feet made no sound on the grass, but he turned suddenly to face her. For the rest of his life, he would never forget her face at that moment.

    "Emma!" he cried.

    The children stood back watching their mother kissing this strange man. He saw them, and kneeling down, he pulled from his pack three huge red apples. In a moment, all three children were in their father's arms. Together, the family entered the little unpainted farmhouse.

    Later that evening, after supper, Smith and his wife went outside. The moon was bright, above the eastern hills. Sweet, peaceful stars filled the sky as the night birds sang softly.

    His farm needed work. His children needed clothing. He was no longer young and strong. But he began to plan for next year. With the same courage he had faced the war, Private Smith faced his difficult future.

    If you have the opportunity to visit some places in New Zealand, then the list below is our recommendation.

    Fiordland National Park

    This park is part of the South Westland World Heritage Area and is New Zealand's largest national park and one of the largest in the world. The scenery in Fiordland is nothing short of extremely beautiful, with steep mountains, wild waterfalls, and abundant rain forests. Being able to come back and forth in its deep bay attracts most of the visitors.

    The area has some of the world's greatest walks including the world famous Milford Track, which was described as the finest walk in the world in the early twentieth century.

    Abel Tasman National Park

    Abel Tasman may be New Zealand's smallest national park, but the attractions are huge. Located in one of New Zealand's sunniest spots, the area also has the best beaches in the country.

    The popular Abel Tasman Walk is a great way to see this park. It takes 3-5 days to complete. Sea taxis are also available and can drop you off at any number of beaches within the park.

    Rotorua

    Accessible from New Zealand's biggest city, Auckland, Rotorua is famous for its volcanic activities. Rotorua is also famous for its plentiful lakes which are great for swimming and fishing. The surrounding area contains plenty of native bushes and some famous walks.

    Rotorua is also the best area in the country to experience and learn about Maori culture.

    Mt Cook National Park

    Mt Cook as well as the surrounding area is an alpine( 高山的) park within the World Heritage listed in South Westland. The biggest peaks in all of Australasia are here. The park doesn't contain many trees or plants due to the altitude. Walks range from a two-hour walk to difficult tracks suitable for experienced mountaineers only.

    A helicopter or plane ride gives visitors excellent views of the mountains with the option of landing at the top of Tasman Glacier, a true permanent snow-covered alpine environment.

    I can proudly say that last year I broke the record for the oldest person in the world to ride a roller-coaster. I'm 105, but I feel younger. Even the doctor agrees I'm in good condition. I'm a bit deaf and my legs feel weak, but they are the only issue.

    I rode the Twistosaurus at Flamingo Land, which spins you round quite fast. I didn't choose to go on that. I'd have preferred a really fast one that went upside down. But I was told I couldn't ride something like that, because my blood pressure could drop and I might have some danger.

    I wasn't nervous — I don't get frightened of anything. I was securely fastened, so I knew I wouldn't fall out. The roller-coaster ride went on for three or four minutes, and it couldn't be a better experience. And I raised a lot of money for the Derbyshire, Leicestershire & Rutland Air Ambulance fund, which was fantastic.

    People were saying I'd got a place in the Guinness World Records. Later, someone came to present me with the certificate. I had it on the wall in my living room, with another one that got a year earlier.

    My record-breaking ways really began a couple of years ago, with the ice-bucket challenge. It turned out that I was probably the oldest person in the world to do it, and the video was very popular. After that, I started to think about what else I could do to raise money for different charities.

    I'm not sure if anyone admires all the fun I'm having. They just say I'm daft and that's about it. But I've had many good days and many exciting times. I've had a really good life. I don't think I've wasted any of it.

    If you're a cycling lover, you will have to pay a lot of attention to your bicycle and maintain it well, for bicycle parts are exposed to wear and tear (磨损) over time and you have to examine the bicycle to see if there are any signs of wearing such as scratches, dents (凹陷) etc. Sometimes, a part may not work because it has exceeded its life expectancy. Sometimes, you will need to find replacement parts for it to keep up the performance of the bicycle.

    Different parts of a bicycle will wear at different rates so it is very important that you have a basic understanding about the role played by each part. One of the most important parts of the bicycle is the frame. You will need to choose a frame that lasts for a very long time. Of course, you will see some paint scratches after some time. When you're selecting a frame, you have to think about the material. Aluminium (铝) frames will not rust easily, but they have a higher chance to dent. Steel frames will be hard to dent, but you will need to make sure they get a good paint job so that they won't rust.

    Wheels also experience a lot of wear and tear and you should go for a professional seller when you want to buy wheels. There are different types of wheels that you can buy, like Zipp wheels that provide more aerodynamic efficiency (空气动力学效能). Investing in new tyres instead of going for used is a good idea because you will be able to get more use out of it. The same goes for chain as there's a higher chance of a used chain breaking. You may also experience shifting problems. However, some parts of bicycles such as pedals can be used for a long time and you can find different styles.

    Other parts that you can buy used are seats, handlebars and the stem. When you are buying handlebars, you have to see if there are any dents or if they have been bent out of shape. There shouldn't be any cracks in the seat post or the handlebars. There are many shops where you can buy parts, so you will have to check the references to see how customers respond to them before you buy anything.

    On the night of December 8, 1992, when he was standing in a parking lot talking to friends, Tracy March jumped to the top of a car, as he had done a hundred times before. This time, though, Tracy lost his balance. His head struck the ground, hard.

    All night, Cory, Tracy's mother, stood next to her son, who was lying in a hospital bed, his brown eyes fixed in a lifeless stare. She remembered that Tracy had once mentioned organ donation. Maybe I can spare another family this pain, she thought. When the time came, she and her husband Bill signed the forms permitting his organs to be donated.

    Tracy was declared dead the next day. Twenty-four hours later, in a Boston hospital, Tracy's liver was made part of my husband, David, who was suffering from a hopeless liver disease.

    Months later, we learned from the local organ bank that the donor's parents wished desperately to meet someone who had gained life through the gift from their son. A meeting was arranged by the organ bank to bring together two families linked by the most bittersweet ties imaginable.

    The meeting was risky, but worth it. We talked for 3 hours. They showed us a picture of Tracy. We learned how he had lived and died. We learned something about Bill and Cory too.

    For the Marches, seeing David and knowing he was well seemed to ease their suffering. I'll never forget seeing David's tall figure stopped over Cory, her arms around his waist, as a mother would hug a son. For a long time they held each other tight. It was hard to know if she was saying hello or good-bye. Maybe she was saying both.
