Walt had a strong commercial sense of what would appeal to the public.Disneyland，Walt Disney World，and finally the other Disney theme parks around the world all came about because Walt Disney insisted that he could build an amusement park that was so much bigger and better than other amusement parks that it shouldn't even be called an amusement park.

    In 1940，he disclosed a plan to show Disney characters in their fantasy surroundings at a park across the street from the Disney studio in Burbank.

    The idea of an amusement park grew in Walt's mind as he traveled through the US and Europe and visited attractions of all kinds.Walt was sure that an amusement park would be successful in the United States if it offered a “good show” that families could enjoy together，was clean，and had friendly employees.

    In 1948，he shared his concept with trusted friends，a modest amusement park with a central village including a town hall，a small park，railroad station，movie theater，and small stores.Outlying areas would include a carnival(联欢) area and a western village.Soon he added spaceship and submarine rides，a steamboat，and exhibit halls.

    Four years later，he decided on “Disneyland” for the name and formed a company to develop the park，Disneyland，Inc.

    In 1953，he got Stanford Research Institute to examine the economic future of Disneyland and to find the perfect location.

    They broke ground in July,1954，and one year later，Disneyland opened.Within 7 weeks，a million visitors had visited Disneyland，making it one of the biggest tourist attractions in the US.

    Walt combined his talent and his sense of what the public would want with lots of hard work.In 1960，with a mixture of huge successes and failures，Disney had created something that was successful beyond Walt's own dreams.

                                                                       Balloon Volleyball

    It's a rainy, dark day and there's nothing to do. You don't feel like sitting quietly but you are not allowed to make a lot of noise. What can you do for fun? Try balloon volleyball.

    Items needed for this game: a balloon (or two, in case the first one bursts), some ropes, two chairs, at least two people and a room.

    Set up the room. If you're in the living room, or a family room, be sure to move all the furniture out of the way. Get two chairs and set them in the middle, outer edges(边缘)of the room. They should be at the same place where you put a volleyball net. Turn them so that the seat is facing the wall, not the “playing” space. Tie the rope onto the top of the chair, and run the rest of the rope to the other chair. Now tie it on this chair at the same place as the first chair. You can decide the “out-of-bounds”(出界) lines, if you want to have them, but they really are not necessary in this game.

    Blow up the balloon. Choose sides. You will play this game on your knees (at least until they start hurting and you want to stand). Each side must get the balloon over the rope in three hits. If it does not get over, the other side gets the balloon and a point. This game becomes more difficult because you must play without talking.

    You can also add other rules to make it more difficult; for example, you can only use your left hand or only your right hand to hit the balloon.

    Continue playing until one side gets 10 points. You can make your game longer or shorter by changing the number of points it takes to win.

    This is a fun way to get your energy out, have fun, and not make too much noise on a rainy, stay-in-the-house day.

    David, a French priest(牧师)of thirty-six, was sent to China by the church in 1872.He did well in the natural and social science besides his religious activities(宗教活动)。He was also very interested in the rare wild animals and plants in China.

    On May 4th, 1879, after searching half a month in the western part of Baoxing, Sichuan the hunters hired(雇用)by David succeeded in bringing him a "black-and-white bear". "The bear is extremely lovely", he wrote in his diary excitedly. Meanwhile, he felt it might be a new species (物种)never discovered by scientists.

    He then decided to send it to Paris for a further study. Unfortunately the poor "black-and white" bear died of Jolts(颠簸)of the mountain roads and the climatic (气候)change. He had to send its pelt (皮毛)to the National Museum in Paris for display (展览)。In fact, the so-called "black-and white" bear was neither a bear nor a cat. After a complete study, Milla Edwards, head of the museum, judged that it was a new species. He gave the "giant panda".

    The discovery made the world excited and Baoxing was also made famous for "home of the giant panda"

    Recently a new study has been carried out. It shows students who write notes by hand during lectures perform better on exams than those who use laptops.

    Students are increasingly using laptops for note-taking because of speed and legibility (清晰度). But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment, students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said, “While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.”

    In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.

    In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."

    The city planner decided to build an underground drainage （排水） system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10jackscrews.At Pullman's signal each man tured his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening.

    Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

    In San Francisco, where the number of the homeless has risen by 7% in the last decade, a non-profit organization is putting bathrooms on wheels and driving them to those in need. The group, Lava Mae, is improving retiring city buses and bringing them into different neighborhoods, currently providing about 200 showers each week.

    Doniece Sandoval, the founder of Lava Mae, first became interested in the issue in 2012, when she passed a young woman under an overpass near the San Francisco Design Center who was repeating to herself that she'd never get clean. "It made me wonder what her chances were," said Sandoval, who was then inspired to research exactly how many public shower stalls（淋浴间）existed in the city. Her findings were disheartening.

    So Lava Mae came together when she heard the city would be retiring cold city buses. "I told myself, I want those buses!" she said.

    Each bus has two private bathrooms, one of which is wheelchair accessible. Along with the basic shower, sink and toilet, the spaces have soft lighting, digital controls for water, and hair dryers.

    "Though you're only going to be on the bus for 20 minutes or so, it's 20 minutes of complete privacy," Said Sandoval.

    The buses are parked near agencies that already serve the homeless. "If we can reduce the amount of time people have to run from place to place to get essential services, we'll be able to make things better," said Sandova.

    What's next for lava Mae? The group is starting a program so that others can mimic their process. " What we're hoping to do is to get people to follow what we do, so they can recreate it." she said.
