A new book called “Battle Hymn of the Tiger Mother” by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.

    Many people are against Amy Chua's parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.

    Ms. Chua says after her younger daughter shouted “I hate my life! I hate you!” she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children's abilities.

    “The debate is about what it means to be a successful parent and what it means to be a successful child,” said Stacy DeBroff, who has written four books on parenting. She says Amy Chua's parenting style is not limited to Chinese families. It is a traditional way of parenting among immigrants (移民). They hope to get a better future for their children.

    She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.

    We've considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing line-cutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service).

    Markets and queues—paying and waiting—are two different ways of allocating things, and each is appropriate to different activities. The morals of the queue, “First come, first served, have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.

    The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it's the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.

    Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank: “Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It's as if the company is trying to ease our impatience with fairness.

    But don't take the recorded message too seriously. Today, some people's calls are answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.

    Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other non-market ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queue-jumping schemes we've considered—at airports and amusement parks, in call centers, doctors' offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.

    Tired of eating at the same boring restaurants? Looking for a change? Here are some restaurants that offer an original restaurant experience. See for yourself which ones you fancy.

    An Exciting Dinner

    Looking for something adventurous? The Archipelago in London is just the thing for you. One of the most popular dishes in this restaurant is crocodile. Yes, you read it correctly, crocodile. If that is not daring enough for you, there are plenty of other dishes on the menu.

    A Restaurant with a View

    Want to enjoy the sights while you're eating? Try the Top of the World restaurant. At about 244 meters above Las Vegas, diners can enjoy a spectacular view of Las Vegas in this revolving restaurant. However, the real adventure starts at the end of the meal. That's when the customers are taken from their seats at ground level to the observation rooms in elevators that travel at a remarkable speed.

    A Theatrical Experience

    Longing for dinner with some drama? Dine with mimes at Mime in Manchester. The service is unique. Your waiter will communicate your order in mime and keep you entertained with performances in between courses.

    An Unusual Setting

    Don't care about presentation? You'll be fine at the Modem Toilet restaurant in Taiwan. The theme of this restaurant is the toilet, and you would be surprised how many people queue up for the experience of eating on toilet seats.

    One day a little boy, annoyed by his father's decision for him to become a grocer, decides that he will never grow up. Grocery is a dull job and staying a child is his protest against it. This strange little boy-man, never separated from a tin drum he is always banging, is our hero of the table. It covers three crucial decades of 20th century history. Little Oscar Matzerath will experience love, war and imprisonment in a story that paints an unforgettable picture of Central Europe between 1923 and 1954.

    This is an overview of the story of The Tin Drum, the most famous work by the German Nobel-winning author Günter Grass, who passed away on April 13 at the age of 87. The Tin Drum also established Grass as one of the leading authors of Germany. It also set a high bar of comparison for all of his following works. Just as his best-known fiction is both the story of an individual and of an age, so it is that Grass' life cannot be understood without referring to the history of Germany. He was called "Germany's conscience", because he reminded Germans of a past during the Second World War (1933-1945) that many would have rather forgotten.

    This sometimes made him unpopular. Many Germans did not agree in 1989 when he said that East Germany and West Germany should remain separate, as a united country would be too strong and threaten the world's peace. And Grass was called a hypocrite when he revealed in his memoir

    Peeling the Onion (2006) that he had been a teenage member of the Waffen-SS, the Nazi (纳粹) Party's fighting force. The man who had blamed the actions of others had a less-than-perfect record himself.

    Grass was a man of the pen and the page and also a man with a gift for speaking to the public.

    His writing was noisy and annoying, but one had to listen to it, a little like the sound of the drum banged by his most famous literary creation.

    I believe children have a very pure sense of humor. Well, I would like to share my experiences with you.

    The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, "Mom, why does it look good but tastes like rubber?" My friend was uneasy. Then the waiter gave us another dish.

    A child can say funny things. I was at a friend's home for tea and her son, Mark, wanted her to get up. His mom replied, "I can't, because my foot has fallen asleep now." Little Mark then sang a song and asked, "Mom, will it wake up now?" We laughed together.

    The other day we were having an interesting conversation over lunch and my friend, an animal activist (积极分子) , was arguing with another group member. Her son Tommy suddenly stood up, “Mom, people should never be allowed to shoot extinct animals!” That was funny and the child did manage to turn the argument into a pleasant conversation.

    Well, children sometimes really surprise us. I think we can have a lot to learn from them. They can help us understand the simple world through their eyes.

    Susan couldn't help it. She and her friends began lunch with cheese. Then they ate cheeseburgers and drank milk. Things seemed fine, but then suddenly Susan's stomach started making noise. Her stomach hurt, and, racing to the restroom, she had terrible gas! She was so ashamed. She had been so excited to go to lunch with her friends that she totally forgot to watch how many dairy products (奶制品) she ate! Susan is lactose intolerant (乳糖不耐受的), and eating too many dairy foods can make her feel really sick.

    Lactose intolerance means that the body can't easily digest (消化) a special sugar called lactose. Unfortunately for Susan and millions of other people with this problem, lactose is found in almost all dairy products — cheese, milk and ice cream.

    Our body uses lactase (乳糖酵素) to break lactose into a simpler form of sugar. Once lactose is broken down, it's easy to digest and it provides great energy for the body. But people like Susan don't have enough lactase to break down all the lactose they take in. So, about half an hour to two hours after eating dairy­rich foods, their stomachs begin to hurt and they have gas, making their stomachs get bigger. Sometimes they even get diarrhea (腹泻) when they eat too many dairy foods.

    So how can someone living with this problem still eat out with his or her friends? Here are some tips. If you're going to eat a dairy­rich food like ice cream, eat something that doesn't have any dairy with it, like a salad or a sandwich without cheese. This will help slow digestion, and your body will have time to create more lactase.
