People who like travelling have their reasons. They believe that travelling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike travelling also have some reasons.

    Travelling, in my opinion, does more good than harm. Most importantly, it broadens  (使扩大) our mind. We can get in touch with other civilizations (文明), cultures, customs and ideas.

    Through history, most people travelled because of necessity (必要性)—not for pleasure. People travelled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever travelled just for the fun of it. In ancient times, for example, rich Romans travelled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity (好奇心). They wanted to find out what it looked like beyond the horizon (地平线). Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.

    So, travelling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.

Hot Spots for Retirees to Start Their Encore Career

    Encore Career: Vocational School Instructor

    Retire in: Los Angeles, CA

    Ever since IBM CEO Ginni Rometty coined the term "new collar" to describe well-paid jobs that require specific skills but not necessarily a degree, vocational schools have made a serious comeback. Apparently instructors are in short supply in sunny L.A., where there are 13 jobs at vocational schools for every applicant on the market. This is a great opportunity for skilled retirees since, unlike teaching at a public school that requires a state certificate, the only requirement here is that you be a seasoned expert in your field.

    Encore Career: Business Consultant

    Retire in: Miami, FL

    Consulting is a great option for a retired business professional looking to make their own hours, be their own boss, and earn as much or as little as needed to maintain their standard of living. For every consultant in Miami right now there are 13 businesses hoping to hire them. There's even greater demand here than in Washington D.C., which is typically considered the consulting capital of the world.

    Encore Career: Tourist Wrangler

    Retire in: Austin, TX

    As the economy continues to boom and more Americans have extra income to spend, the tourism industry has taken off. This is particularly true in Austin, TX, where there were astonishing 36 tourism jobs for every applicant in July. Between four-star hotels, the noisy rock n' roll scene, and a new food culture, Austin is the place to be if you want to work in service industry.

    Retire in: Charleston, SC

    If you're a Baby Boomer with a degree in the arts, now could be the perfect time to revisit your passion for creativity, especially if you also want to live in the center of southern charm. Between the 14 art galleries on King Street in Old Town, an abundance of acting companies and theaters, and music festivals, it's not surprising there were 25 jobs for every arty applicant iii Charleston.

    Robots are increasingly being developed to think and act like humans. But it is difficult for engineers to create humor (幽默) in machines. Computer scientists have hoped to help them understand humor. But they failed again and again. Why is it so difficult?

    Kiki, a computer language expert (专家), studies humor at a university. "Most robots are powered by artificial intelligence (人工智能AI). But AI will never understand jokes like humans do." He said, "The main problem is that AI system doesn't have the sense of humor."

    Other experts agree that context (语境) is very important to understand humor, both for humans and robots. In one project, Tristan Miller, a computer scientist, studied more than 10, 000 puns. Puns are a kind of joke that uses a word with two meanings. For example, you could say, "Balloons (气球) do not like pop music." The word "pop" can be a way of saying popular music, or "pop" can be the sound a balloon makes when it explodes(爆炸). "A robot might not understand the joke because it doesn't know the meaning of the puns." Miller said.

    Although it's difficult, some scientists say there are good reasons to keep trying to teach humor to robots. It can make machines understand humans better and serve humans better. And it can also help them to think more like humans.

    But other scientists don't think it's a good idea to teach humor to robots. They may find humor, but they may use it in a wrong way. Maybe bad Al will start killing people because it thinks it is funny. Besides, it may make some people feel not safe. The comedians(喜剧演员) may lose their jobs when the robots can understand humor.

     At one time, computers were expected largely to remove the need for paper copies of documents because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

     It is difficult to measure the quantity of paper used as a result of the use of Internet-connected computers, although just about anyone who works in an office can tell you that when email is introduced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down," says Ted Smith of the Earth Village Organization.  

     Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just an online email, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.

     Does all this mean environmental concerns have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. "I guess people believe that the problem is taken care of, because of recycling," said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity.

     The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.

Dickens House Museum

Type: Historic House / Palace

Address: 2 Victoria Parade, Broadstairs, Kent, CT10 1QS

About

Dickens House Museum, Broadstairs celebrates Charles Dickens' long connection with Broadstairs from 1837 to 1851, through personal items and letters. Guided tours available.

The museum is housed in the cottage that was Charles Dickens' inspiration for the home of Betsey Trotwood in David Copperfield. David's description of Betsey's cottage with its square gravelled garden full of flowers, and a parlour of old fashioned furniture still fits today.

The character Betsy Trotwood is based on Miss Mary Pearson Strong who lived in the cottage that is now the museum. According to the reminiscences of Charles Dickens' son Charley, he and his father regularly had tea and cakes in the parlour (会客室) with the kindly and charming Miss Mary Pearson Strong. He also remembers that Miss Pearson Strong was completely convinced of her right to stop the passage of donkeys along the cliff top in front of her cottage. This belief became the donkey incident for the character of Betsy Trotwood, with the famous quote: "Janet! Donkeys!"

Spread over four floors, the Charles Dickens Museum holds the world's most important collection of paintings, rare editions, manuscripts, original furniture and other items relating to the life and work of Dickens. Perhaps the best-known exhibit is the portrait of Dickens known as Dickens' Dream by R. W. Buss, an original illustrator of The Pickwick Papers. This unfinished portrait shows Dickens in his study at Gads Hill Place surrounded by many of the characters he had created.
