    Everglades National Park (大沼泽地国家公园) is located in the state of Florida. It is the largest wilderness in the entire country and makes up 25% of the wetlands in the state. The park is home to several rare and endangered species. It is also the third largest national park in the US, after Death Valley and Yellowstone. Each year, about 1 million tourists visit the park. On a global level, it has been announced as a World Heritage Site.

    Unlike most other national parks, Everglades National Park was created to protect an ecosystem (生态系统) from damage. In 1947, President Harry Truman spoke at the official opening of Everglades National Park, saying the goal of creating the park was to protect forever a wild area that could never be replaced.

    10,000 different islands make up Everglades National Park. Each of these islands is lived by natural wildlife. The Everglades is home to about 15 species that are endangered. In addition, more than 350 bird species and 300 species of fresh and saltwater fish live within the park. The Everglades is also home to 40 species of mammals and 50 reptile species.

    There are many ways to explore the Everglades. Visitors can see alligators (短吻鳄) while hiking the Anhinga Trail. The Everglades is one of the only places on Earth where freshwater alligators and saltwater crocodiles live in the same area. Visitors using airboats are likely to see large groups of birds. Some visitors might enjoy riding bicycles through Shark Valley. Others may want to move slowly through waters where they can see insects and wildlife closely.

    According to experts, changes to the Everglades are becoming a danger to several different kinds of wildlife. They say it is a result of actions the US government began more than 50 years ago, and settlers began even earlier.

    When it's five o'clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clocks tell them they're done.

    These days, the time is everywhere: not just on clocks or watches, but on cellphones and computers. That may be a bad thing, particularly at work. New research shows that clock based work schedules hinder creativity.

    Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 a. m. to 10 a. m, research from 10 a. m to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.

    What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities from project planning, holiday shopping, to yoga by time or to-do list to measure how they performed under "clock time" vs. " task time". They found clock timers to be more efficient(有效率的) but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.

    The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture. This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.

    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.

    The world we live in gets more mechanized every year. Some countries which were mainly agricultural a hundred years ago have now become industrial. New factories and towns have been built on good agricultural land. There are now fewer farms to serve a much greater population, so these farms must be more efficient in order to produce as much food as possible. There is no place in the modern agricultural world for the inefficient farmer. Unfortunately, many of the picturesque aspects of farming are disappearing in the search for efficiency. The more tractors are used, the fewer horses are needed. Everyone agrees that horses are far more pleasant to look at than tractors. But they are less efficient. Cows are usually milked by machinery nowadays, and even pigs are fed automatically. There is not much art or poetry on the modern farm, and the old traditional idea of a farm as a slow, peaceful, romantic place is totally wrong nowadays.

    The modern farmer has to be a mechanic, a scientist, an accountant and a gambler. The more mechanized farming becomes, the more expert the farmer has to be. He must understand what machinery is necessary for his kind of farm, and he must know how to use it efficiently. He must also understand the new technical advances in agriculture, and how to use chemical and synthetic products to improve his crops. The more workers a farmer employs, the more he must know about the problems of wages and taxes. As in any other industry, most modern farmers find it necessary to employ office staff to deal with these. But although he has more modern equipments and far more scientific aids than his grandfather had, the farmer is still dependent upon the weather. As he can never be sure what the weather will do, he must be prepared to take risks, and face the possibility of losing everything.

Table Talk

As we got out of the car, our son announced, "Phones stay in the car."

"Why do you always have to tell us that?" complained our fifteen-year-old grandson.

Our son's wife winked at us and then explained, "We have a family1 that no one may bring anything electronic to the table."

We 2 our phones in the car. Even though the restaurant was filled with families, there was little noise. All I heard were a few quiet conversations and the ding of forks on plates. The 3 unnerved me. I looked around. Everyone, even the young kids, was 4 at some kind of screen. 

The silence was broken when the six of us sat down, and started talking. The waitress stood patiently and waited for our orders. When our food came, we continued to chat. 

An elderly couple at the next table were finishing their dinners and conversing quietly. I noticed that they shot us a few glances, and wondered if our constant chatter was annoying them. 

After the dessert, my son signaled the waitress for the check. She hesitated when she brought the black folder to our table. My son opened the black folder — it was5 . "You forgot the check," he told her.

"There isn't one. Someone else6 your bill — and the tip too." she said with a giggle (咯咯笑).

"Why?" asked our son, his wife and myself at once.

"They loved it that no one was connected." she continued. "They loved watching you guys7 . The old lady went on and on about how nice it was to see a family eating and talking instead of looking at ‘electric games'."

For a moment, everyone at our table was at a loss for8 . Then we all started talking at once. My son's voice rose above the others. "Where are they? We want to thank them."

"They left after you ordered dessert," the waitress replied.

We spent the next fifteen minutes discussing this goodness and camp up with a 9 . Next time we see a family eating at a restaurant 10 looking at anything electronic, we'll pay it forward, just like what happened to us.
