Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual（虚拟）. The site now has more than one million members in more than one hundred thirty-five countries.

    Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16th century, people thought that dirt on the skin was a way to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let illnesses in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus it began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children of touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    Yesterday I went to the nursing home to visit my grandma. She just got out of the hospital recently where she had some serious operations. I wanted to surprise her after work so I stopped by for a quick visit.

    When I got there, she was so happy to see me. We hugged, kissed and exchanged greetings. Then I heard a woman crying. It was my grandma's roommate. The curtain was drawn so I could not see her. She started calling out a name that wasn't mine but she was certainly talking to me, begging me to go to her side of the room.

I ignored her at first and continued talking with my grandma. Then she started begging and saying, "Please, come to see me!" So I went to see her.

    When I drew the curtain back, she looked so old but flashed me the biggest smile! She opened her arms wide for me to hug her so I bent low and gave her a hug. I sat on her bed and talked with her for a few minutes. She kept calling me by the other name, but I did not correct her. She told me stories as if I had been there when they happened.

Finally I went back to talk with my grandma. Then the woman started crying again, saying, "Please, come back." She finally slept.

    I stopped by the nurse's station and the nurse told me that the lady suffers from Alzheimer's (老年痴呆症). I mentioned the name she had called me. The nurse told me it was the lady's daughter's name. Then I understood why she wanted me to go to visit her.

    We will all get old some day. Some of us will have broken minds like the lady and some of us will have broken bodies like my grandma. As I was leaving, I promised I would go back and visit the lady, even after my grandma moved back to her home.

    Watching wooden dolls come to life may not be one of the most popular forms of entertainment today, but with over twenty years' experience, talented puppeteer (木偶表演者) Peter Roberts has earned himself the title "master puppeteer" because of his great ability to turn puppets into believable, almost living characters. "People are quite often surprised to hear what I do for a living and have little appreciation of puppy as a form of entertainment. But while the exact origins of puppet theatre are unknown, it has been popular in many cultures and may have been the very first kind of theatre," he explains.

    Roberts' shows are highly original. "A puppet show can involve anything from clowning(傻逗) to storytelling," he says.  Equally diverse are the audiences he performs for. "Some are attracted by the puppets themselves, while others enjoy the dialogue." Roberts believes that this form of entertainment can be appreciated by people of all ages and cultures.

    Roberts' interest in puppets started when he received some beautiful glove puppets one Christmas. He started putting on shows with these for family and friends and then moved on to handmade Chinese string puppets. Learning mostly from books and personal experience, he explains, "I was already spending most of my free time carving puppets and putting on shows, so I hardly noticed the change from students to full-time professional puppeteer."

    The puppets are designed specifically for each show, which is extremely time consuming. According to Roberts, "Sometimes what you expect and what you actually create in the end are two very different things. I've made some of my best puppets 'accidentally'."

    When most people hear the word "puppetry", they more than likely think of a way of keeping children entertained at birthday parties. Certainly the subject matter will be expected to be light-hearted rather than serious. However, Roberts wants to point out that puppets convey serious messages sometimes." he says.

    AA famous magazine, Amusement Today, does a survey among park lovers every year both in the US and overseas, based on which, "Top 5 List of the Best Amusement Parks in the World" has come out as follows:

How much of your monthly grocery list ends up in the garbage? A new study reveals the average American spends nearly $1,500 per year on food they'll never eat.

A recent survey of 2,000 Americans reveals the average shopper wastes $1,493.93 on food per year. That's almost a fifth of their grocery bill after every shopping trip. One tenth of respondents claim they "never" purchase food they don't end up eating, while three in 10 say this is something they "always" do.

Half of respondents prefer to head to the grocery store alone, and when they do, half are more likely to stick to their list and 36% are less likely to buy food they don't want or need.

Keeping the list in mind is important, as 38 percent are more likely to let food be wasted if it wasn't originally on their shopping list. Seven in 10 add that when they go to the store on an empty stomach, they're more likely to buy foods they won't eat. So they don't do that that way. Some respondents appear to be in a wasteful cycle when it comes to food waste. Nearly half usually buy and end up wasting the same food every month because they think they'll get around to eating it.

"We can all do better to limit food waste by sticking to grocery lists and, when we get home, prioritizing eating our foods that are_perishable, like fruits, vegetables, and dairy products" says Avocado Co-Founder and CMO Mark Abrials in a statement.

Three-quarters feel guilty about throwing away uneaten food because it's a waste of money — and 48 percent feel the same, due to the harm food waste causes to the environment. "When it comes to food waste, nobody is perfect," Abrials adds. "But in order to consider our environmental impact, not to mention wasted money, we think it's essential to be thoughtful about everything we purchase — whether that's food, mattresses or other goods."
