Weddings in the United States vary as much as the people do. There are church weddings with a great deal of fanfare(仪式上的短曲); there are weddings on mountain tops with guests barefooted; there have been weddings on the ocean floor with oxygen tanks for the guests. But many weddings, no matter where or how they are performed, include certain traditional customs.

    Before a couple is married, they become engaged. And then invitations are sent to those who live nearby, their close friends and their relatives who live far away. When everything is ready, then comes the most exciting moment.

    The wedding itself usually lasts between 30 and 40 minutes. The wedding party enters the church while the wedding march is played. The bride carrying a bouquet enters last with her father who will “give her away”. The groom enters the church from a side door. When the wedding party is gathered by the altar, the bride and groom exchange vows(誓言). It is traditional to use the words “to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, till death do us part.” Following the vows, the couple exchange rings. Wearing the wedding rings on the fourth finger of the left hand is an old custom.

    After the ceremony, there is often a party, called a “reception” which gives the wedding guests an opportunity to congratulate the new couple.

    The car in which the couple leaves the church is decorated with balloons. The words “Just Married” are painted on the trunk or back window. And then the couple go in their honeymoon.

    It used to be a matter of fact when Peter Pan-a character from James Matthew Harrie's 1911 book-said: “All children, except one, grow up.”

    But this “fact” doesn't seem to apply to today's world anymore.

    According to the NPD Group, a US market research company, sales of toys to adults in the UK increased by more than 20 percent in 2016, three times the pace of the children's toy market itself. These toys varied from puzzles and Lego building sets to vehicle models and action figures. And more than half of the sales came from millennials-people born between the 1980s and 2000s.

    “Adults of the 21st century are channeling their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes looked to as “kidults”.

    According to Frederique Tutt, an analyst at NPD, the motivation of these grown-ups is to escape the stress of today's fast-paced world. They are driven toward the more immediate pleasures brought by toys than those brought by, say, getting a promotion, which is far less easy to achieve.

    “It reminds me of the playful side of life,” Rob Willner, a 25-year-old PhD student in the UK, told The Telegraph when talking about his love for Lego, which he said brings him both comfort and pleasure.

    Despite this, some social scientists see the trend as disturbing. To Frank Furendi, a professor at the University of Kent in the UK, the fact that so many adults are seeking “the excitement of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times. “That's actually quite sad.”

    But scientists are probably just worrying too much. According to Canadian comic book artist Todd McFarlane, collecting toys could simply be a way for people to express their individuality. “It's just pop culture stuff. It's stuff that says, ‘I like a little of this and I like a little of that',” he told ABC News. “It's no big deal.”

    So now that over 100 years have passed since Peter Pan, perhaps it's time to introduce a new “fact”, as stated in the tagline(标语) of the UK fashion brand KIDULT: “Growing old is mandatory (被迫的), but growing up is optional.”

    It may surprise bookworms, but apparently masterpieces such as Jane Eyre are lacking in something — sound effects. An electronic-book firm is adding background noises and music to the works of Charlotte Bronte, Sir Arthur Conan Doyle and William Shakespeare in the hope of attracting younger readers. In one example, a description of rain lashing against a window in a Sherlock Holmes story will be“enhanced”with matching noises.

    The first multimedia e-books — with sounds to accompany novels — will be available this Friday in the UK. The Booktrack releases are available to iPad users, with other tablet computer versions to follow. The concept is already in use in the U.S., where the classics come with added sound effects. Readers for example can hear the china cups chinking in Mr. Darcy's garden as they read Pride And Prejudice.

    A story by Booker Prize winner Salman Rushdie will be released later in the year with a specially crafted orchestral score. Rushdie's story In The South will be released with a soundtrack provided by the New Zealand Symphony Orchestra.

    The Power Of Six by Pittacus Lore, a novel for young adults, is one of the first to be tested with a soundtrack which builds in suspense in keeping with the plot. It works by timing the speed of each reader and the software measures the “turning” of a page and moves the music or sounds along accordingly. It has been created by Booktrack which synchronizes (使同步) music to each novel. It is funded by Peter Thiel, a co-founder of PayPal.

    Mr. Thiel said, “It's always exciting to witness the creation of a new form of media. The technology promises to captivate readers in a different way.”

    However, they have been greeted with horror by traditionalists, who say the technology takes away the pleasure of having one's imagination stimulated by a story. They also raise the prospect (预期) of having to ask an overly eager reader to turn their book down. David Nicholls, whose bestseller One Day was recently turned into a film starring Anne Hathaway, said, “This sounds like the opposite of reading. It would be a distraction.”

    It seems that you can hardly go to any bookstore without encountering Charles Dickens. From Oliver Twist to A Tale of Two Cites, Dickens' works still enjoy great popularity today and are placed on notable shelves.

    As someone who teaches Dickens, the question of why we still read him is often on my min. Nearly 10 years ago, I told my students that Dickens, works started crazes in Victorian readers. Then a hand shot up in the middle of the room. “But why should we still read his stuff?” A student asked. I was speechless because I had never considered the question myself. The answer I gave was only acceptable. “Because he teaches you how to think,” I said.

    The question annoyed me for years, and for years I told myself answers, but never with complete satisfaction. We read Dickens because he not only was a man of his own times, but also is a man for our times. We read Dickens because his exploration of the human mind is deep. We read Dickens because we can learn from the experiences of his characters. These are all wonderful reasons, but not exactly the reasons why I read Dickens.

    My search for an answer continued in vain, until one day a text message came from a student of mine. “We still read Dickens' novels,” she wrote, “because they tell us why we are what we are.” Simple as it was, that was the explanation I had thought for years.

    Like most people, I think I knew who I was without knowing it. I was Oliver Twist, always wanting and asking for more. I was Nicholas Nickleby, convinced that my father was watching me from beyond the grave. I was Pip, in love with someone far beyond my reach. I was all of these characters, and I began to understand more about why I was who I was because Dickens had told me so much about human beings. Dickens shines a light on who we are during the best and worst of times. That's why we still need to read him today.

    Right now, I am looking at a shelf full of relics, a collection of has-beens, old-timers, antiques, fossils. Right now, I am looking at a shelf full of books. Yes, that's right. If you have some spare cash (the going rate is about $89) and you are looking to enhance your reading experience, then I highly suggest you consider purchasing an e-reader. E-readers are replacing the books of old and I welcome them with open arms (as you should).

    An e-reader is a device that allows you to read e-books. An e-book is a book-length publication in digital form, consisting of text, images or both, and produced on, published through and readable on computers or other electronic devices. Sometimes the equivalent of a conventional printed book, e-books can also be born digital. The Oxford Dictionary of English defines the e-book as "an electronic version of a printed book", but e-books can and do exist without any printed equivalent.

    E-readers put printed books to shame. E-readers are superior to printed books because they save space, are environmentally friendly and provide helpful reading tips and tools that printed books do not.

    The average e-reader can store thousands of digital books, providing a genuine library at your fingertips. What is more, the e-reader itself is very small. It is easy to hold and can fit in a pocketbook or briefcase easily. This makes handling wooden giant such as War and Peace and Anna Karenina a breeze. Perhaps the only drawback to the space-saving aspect of an e-reader is that it requires you to find new things to put on your shelves.

    In addition, e-readers are environmentally friendly. The average novel is about 300 pages long. So, if a novel is printed 1000 times, it will use 300,000 pieces of paper. That's a lot of paper! And for the super bestsellers, these figures increase dramatically. For example, the Harry Potter book series has sold over 450 million copies. That's about 2 million trees! Upon viewing these figures, it is not hard to grasp the severe impact of printed books on the environment. Since e-readers use no trees, they represent a significant amount of preservation in terms of the environment and its resources.

    Finally, e-readers provide helpful reading tips and tools that printed books do not. The typical e-reader allows its user to adjust letter size, letterform and line spacing. It also allows highlighting and electronic bookmarking.

    Furthermore, it grants users the ability to get an overview of a book and then jump to a specific location based on that overview. While these are all nice features, perhaps the most helpful of all is the ability to get dictionary definitions at the touch of a finger. On even the most basic e-reader, users can find instant definitions without having to hunt through a physical dictionary.

    It can be seen that e-readers are superior to printed books. They save space, are environmentally friendly and provide helpful reading tips and tools that printed books do not. So what good are printed books? Well, they certainly make nice decorations.

    For the first time, China's South Pole researchers can eat fresh vegetables grown regularly, according to Wang Zheng, the grower, who came home last month after a 400-day mission in Antarctica.

    "Growing vegetables in Antarctica reminded me of The Martian, a sci-fi movie about an astronaut who survives alone on Mars by eating potatoes he grows there," Wang said on Friday. "I totally understand the main character of the movie, I understand how he feels when he watches a small green plant grow in a fragile man-made environment,'' said the 40-year-old doctor. But he admitted that the conditions he faced in the Antarctic were much better than those in the film.

    Wang said the growth chamber(生长室) at the Zhongshan Station, had only a low yield when it was established in 2013. The amount was too small to make it possible for researchers to have vegetable dishes. To increase the yield, he reduced the number of vegetable varieties and focused on only some fast-growing ones, which makes the output stable. As a result, during much of his stay there, at least one vegetable dish, such as cucumbers, lettuce or cabbage, was served at every meal for a group of 18 researchers.

    Wang, an orthopedist, said he knew nothing about botany or farming before he arrived at the station in December, 2014. "I was given this job probably because my office is next to the growth chamber, and as a doctor, I had more spare time than others," Wang said. He considered many factors, such as light, temperature and humidity. Light music is played in the 16-square - meter greenhouse around the clock. "Mild music is good for vegetable growth," he said. "We also played Buddhist music, which has soft melody."

    "Growers before me did very good work. My job was to maintain the chamber and keep everything working." Before the  harvest, researchers had a very limited vegetable supply—mostly potatoes and cabbage, which taste awful after months of storage. "Because of our success in growing vegetables, we can have fresh vegetables every day," he said. "The Russian station is no more than one kilometer away from ours. We even had enough vegetables to invite our Russian colleagues for dinner."
