    Discovering Tasmania

    The island of Tasmania a place of natural beauty and has more than 2,000 km of walking tracks and 18 national parks. If you go on a tour, you'll discover a wild and beautiful place where the people are friendly and the food is delicious. If you don't like walking, there are other tours you can choose from including a river cruise(巡游) and cycling. You can also enjoy fishing, sailing or sunbathing on the beach.

    The Tarkine coast is located in the northwest of Tasmania. It's such a wild and remote(偏僻) area that you can easily complete your walk without seeing anyone apart from the members of your group and your two guides. The area contains the largest rainforest in Australia which is home to more than 50 endangered species. It is also home to many Aboriginal Heritage Sites. During your tour, you'll come across rivers, mountain ranges, waterfalls, wildlife and long wild beaches.

    Tour Itinerary：

    Day 1：

    You're picked up from your hotel in Launceston and driven to the Tarkine. You then complete a three­hour walk through the forest before arriving at your camp at Mystery Creek. There you will enjoy a delicious meal cooked by your guides.

    Day 2：

    After breakfast, you continue deeper into the rainforest, passing some of the tallest trees in the world as you go, and stopping for lunch and then camp in the evening.

    Day 3：

    The exciting part of today's tour is the Tarkine Falls, a beautiful 15­metre waterfall.

    Day 4：

    You can stay at the camp and bathe in the Tarkine Falls, or you can go for a walk for more fantastic views of the forest.

    Day 5：

    After a last journey through the forest, you are picked up at about 4：00 p．m. and you arrive in Launceston at around 7：00 p．m.

    The tour includes two professional guides, transport to and from the rainforest, all food while on the tours and all safety equipment. You should buy or hire(租用) recommended camping equipment including: backpacks, sleeping bags, rain coats and trousers.

    After Mom died, I began visiting Dad every morning before I went to work. He was frail and moved slowly, but he always had a glass of freshly squeezed orange juice on the kitchen table for me, along with an unsigned note reading, "Drink your juice." Such a gesture, I knew, was as far as Dad had ever been able to go in expressing his love. In fact, I remember, as a kid I had questioned Mom "Why doesn't Dad love me?" Mom frowned, "Who said he doesn't love you?" "Well, he never tells me," I complained. "He never tells me either," she said, smiling. "But look how hard he works to take care of us, to buy us food and clothes, and to pay for this house. That's how your father tells us he loves us."

    I nodded slowly. I understood in my head, but not in my heart. I still wanted my father to put his arms around me and tell me he loved me. Dad owned and operated a small scrap (片) metal business, and after school I often hung around while he worked. Dad fed scrap steel into a machine which looked like a giant pair of scissors with blades thicker than my father's body. If he didn't feed those terrifying blades just right, he risked serious injury. "Why don't you hire someone to do that for you?" Mom asked Dad one night as she bent over him and rubbed his aching shoulders . "Why don't you hire a cook?" Dad asked, giving her one of his rare smiles.

    Many years later, during my first daily visit, after drinking the juice my father had squeezed for me, I walked over, hugged him and said, "I love you, Dad." From then on I did this every morning. My father never told me how he felt about my hugs, and there was never any expression on his face when I gave them.

    Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the "private" moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.

    Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.

    Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.

    Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.

    Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California's Channel Islands.

    However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.

    The belief that new technologies are causing the death of work is the idea that never goes away. Despite evidence to the contrary, we still view technological change today as being more rapid and dramatic in its consequences for work than ever before. But this is nothing new. People have always viewed the technological changes that take place during their lives as the most dramatic and dangerous that ever happened in history.

    In the 1930s, the British economist(经济学家) John Maynard Keynes predicted the widespread use of electricity would produce a world where people spend most of their time doing nothing. In the United States during the 1960s, the government repeatedly investigates fears that automatic machines would permanently reduce the amount of work available. In 1988, one Australian historian claimed that at least a quarter of the workforce would be without jobs within 10 years because of computers.

    Of course, none of these disasters came to pass in the United Kingdom, the United States and Australia, or anywhere else.

    Yet today, we are seeing the return of these predictions, with some experts claiming the world of work is once more undergoing radical(激进的)and unprecedented(前所未有的) change. They argue that robots and other workplace technologies are causing a reduction in the total amount of work available, or are bringing a more rapid pace of substitution of machines for humans than has been seen previously.

    But there is a little evidence to support such beliefs. Statistics show that the percentage of people in work, the number of hours they work, and how frequently they change jobs have remained remarkably constant over the past 20 years.

    This stability should not come as a surprise. There are good reasons why we should not expect new technologies to cause the death of work. New technologies always cause job losses, but that is only part of the story. What also needs to be understood is how they increase the amount of work available.

    One way this happens is through the increases in incomes that accompany the use of new technologies. With the introduction of these technologies, goods and services can be produced faster, which results in higher real incomes for workers. Higher incomes then increase demand for other products and consequently more workers are needed to make them. Additionally, while new technologies are likely to substitute for some types of workers, they will also increase demand for other types of workers, especially those with higher level skills and expertise.

    So, the end of work is no closer today than at any time in the past. But there is still a need to keep disproving the prediction, to reduce people's fears.

    Dutch officials toasted on Tuesday the opening of what is being called the world's first 3D-printed concrete bridge, which is meant to be used by cyclists. There was applause as officials wearing hard hats and workmen's jackets rode over the bridge on their bikes at the opening ceremony in the southeastern town of Gemert.

    "The bridge is not very big, but it was rolled out by a printer which makes it unique," Theo Salet, from the Eindhoven University of Technology, told Dutch broadcaster NOS. Work on printing the bridge, which has some 800 layers, took about three months after starting in June and it is made of pre-stressed concrete, according to the university. "One of the advantages of printing a bridge is that much less concrete is needed than in the conventional technique in which a mould (泥浆) is filled," it said on its website, adding "a printer deposits the concrete only where it is needed."

    The eight-metre (26-foot) bridge crosses a water-filled channel to connect two roads, and it was tested for safety to bear loads of up to two metric tons in cooperation with the BAM Infra Construction company. Although designed for bikes, it could take up to 40 trucks, the designers said "We are looking to the future," said the head of BAM, Marinus Schimmel. "3D printing meant fewer rare resources were needed and there was significantly less waste," he added.

    The Netherlands is among countries, with the United States and China, taking a lead in the cutting-edge technology of 3D printing, using computers and robotics to construct objects and structures from scratch without using much traditional manpower. Last year a Dutch architect unveiled (提示) a unique 3D printer with which he hopes to construct an "endless loop" building. And a Dutch start-up called MX3D has begun printing a stainless-steel bridge, of which a third is already completed. The aim is to finish printing by March and lay the bridge over an Amsterdam canal in the future.
