Dick lived in England. One day in January he said to his wife, "I'm going to fly to New York next week because I've got some work there." "Where are you going to stay there?" his wife asked. "I don't know yet." Dick answered. "Please send me your address from there in a telegram (电报)," his wife said. "All right," Dick answered.

    He flew to New York on January 31st and found a nice hotel in the center of the city. He put his things in his room and then he sent his wife a telegram. He put the address of his hotel in it.

    In the evening he didn't have any work, so he went to a cinema. He came out at nine o'clock and said, "Now I'm going back to my hotel and have a nice dinner."

    He found a taxi (出租车) and the driver said, "Where do you want to go?" But Dick didn't remember the name and address of his hotel.

    "Which hotel are my things in?" he said, "And what am I going to do tonight?" But the driver of the taxi did not know. So Dick got out and went into a post office. There he sent his wife another telegram, and in it he wrote, "Please send me my address at this post office."

    Jane Austen, a famous English writer, was born at Steventon, Hampshire, on December 16, 1775, and died on July 18, 1817. She began writing early in life, although the prejudices of her times forced her to have her books published anonymously (匿名).

    But Jane Austen is perhaps the best known and best loved of Bath's many famous local people and visitors. She paid two long visits here during the last five years of the eighteenth century and from 1801 to 1806, Bath was her home. Her deep knowledge of the city is fully seen in two of her novels, Northanger Abbey and Persuasion, which are largely set in Bath. The city is still very much as Jane Austen knew it, keeping in its streets and public buildings the well-ordered world that she described so well in her novels. Now the pleasure of learning Jane Austen's Bath can be enhanced (增强)by visiting the Jane Austen Centre in Gay Street. Here, in a Georgian town house in the heart of the city, you can find out more about Bath in Jane Austen's time and the importance of Bath in her life and work.

    The Centre has been set up with the help and guidance of members of the Jane Austen Society. After your visit to the Centre, you can look round the attractive shop, which offers a huge collection of Jane Austen related books, cards and many specially designed gifts. Jane Austen quizzes are offered to keep the children busy.

    You can also have walking tours of Jane Austen's Bath, which is a great way to find out more about Jane Austen and discover the wonderful Georgian city of Bath. The tour lasts about one and a half hours. The experienced guides will take you to the places where Jane lived, walked and shopped.

    One of the most important aspects of an image is color. People are very sensitive to color, and different colors have different on people.

    In general, red is an exciting color, which creates an image of action, energy danger. Red is also the most frequently used color in flags. Eighty percent of the world's flags contain red. A study in Germany showed that football teams wearing red are more successful. Blue is a very calm color. Business executives usually wear dark blue suits. Blue is also a peaceful color. The flag of the United Nations is light blue. Yellow is associated with openness and freedom. Green is a very relaxing color. Surgeons nowadays wear green, because it's less tiring than white. Black creates an image of power and authority. It can also be a very threatening color. Gangsters and vampires often wear black, white is a pure and strong color. This is one reason why doctors wear white coats. We trust them more. Grey is a very anonymouscolor. People wearing grey don't want other people to notice them. Brown is the opposite of black. It's warm and friendly, while black is threatening

    Learning is so complex that there are many different psychological theories to explain how people learn. A psychologist named Albert Bandura suggested a social learning theory which shows that observation, imitation (模仿), and modeling play a primary role in this process.

    In Albert Bandura's opinion, people can learn through observation. Observational learning doesn't even necessarily require watching another person join in an activity. We can also learn by reading, hearing, or watching the actions of characters in books and films. However, just observing someone else's actions isn't always enough to lead to learning. Your own mental state also plays an important role in determining whether a behavior is learned or not. In addition, though in many cases, learning can be seen immediately when the new behavior is displayed, yet sometimes we can learn things even though that learning might not be immediately obvious, which means people can learn new information without showing new behaviors.

    Not all observed behaviors are effectively learned. Certain requirements need to be related to the observational learning process. For example, you need to be paying attention. Also your retention is an important part of observational learning as you need to pull up information later and act on it during the process. Once you've paid attention to the model and kept the information, it's time to actually perform the behavior you observed. Further practice of the learned behavior leads to improvement. Finally, you have to be motivated to imitate the behavior that has been modeled.

    Social learning theory have many real-world applications. For example, researchers employ it to look into and understand ways that positive role models can be used to encourage desirable behaviors. Besides, it's also applied in the field of education, and today, both teachers and parents recognize how important it is to model appropriate behaviors.

    Bike sharing have become popular words in cities from Cape Town to Shanghai to Melbourne. Planners, politicians and media keep showing off their benefits: reducing pollution, congestion, travel costs and oil dependence, while improving public health. Bike sharing also helps make cities appear modern, dynamic and worldwide--qualities much sought after by the creative class.

    But what makes for a successful public bike-sharing program? This is an important question because installing one requires significant public and private investment and adjustment to the built environment.

    While many programs have been launched among much praise, often their popularity has soon declined. Many end up operating at a financial loss and depend on other profitable enterprises to cross-subsidize (交叉补贴) them. Some have resulted in thrown-away bikes becoming an eyesore.

    Understanding which factors enhance or stop public bike sharing is critical in helping cities decide whether such a program is workable, before considering what design and sitting will work best.

    Drawing on current knowledge, we discuss the importance of the local landscape, climate, cycling infrastructure (基础设施) and land use. We also touch on other factors, such as the legal environment and the characteristics of the bike-sharing program itself.

    Take natural environment for example. Two natural environment factors are known to affect participation: hilliness and weather. Hilliness discourages balanced bike-sharing use, as users avoid returning bicycles to stations on hilltops. Those stations end up being empty, while stations on flat areas are often full, so users cannot find a station to return their bikes.

    As for weather, ideal temperature ranges vary by the climate zone. Case studies show warm and dry weather encourages public bike-sharing use. Rain and strong wind reduce the frequency of trips. However, some approaches, such as providing sheltered, shaded, or even heated or cooled cycling infrastructure, could prove useful.

Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.

The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.

One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.

A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.

A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.

Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.
