Do you love holidays but hate the increase weight that follows? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.

    Do not miss meals. Before you leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(过多的) calories.

Carol: I started playing the cello（大提琴）when I was about eight or nine. It was great playing the cello because I was in youth orchestras and we went abroad to do tours. But anyway, when I got to university, I stopped playing. Well, there just wasn't time and there were so many other things to do. Luckily, I took it up after my 25^th birthday and joined a band.

Daniel: When I was little, I thought I'd end up learning the guitar like my father, but then I decided that I wanted to have my own instrument, so I chose the trumpet（小号）. I'm in the school jazz band and I'd like to be a musician when I grow up, but my dad says it's difficult to make a living from music. But I don't want to be a lawyer like him. It's so boring.

Carmen: Nobody likes living near someone like me because when I practice, I make a lot of noise! But you have to keep practicing, don't you? Otherwise it gets more and more difficult. The trouble is, in the summer, when it's hot, I have to open the windows, so the whole street gets to hear it if I'm not careful. I love playing the drums and I play in a fantastic band.

Vince: I've played the guitar for as long as I can remember, but when I was trying to make it as a musician after school, I used to play in the Underground in London to make a bit of extra money. I kept on playing, but I ran a restaurant to make a living. When I get any spare time I still play. I've got a few friends who like music too and we have formed a band.

    A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations（语调）of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted（闪烁）at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up – the product of his sacrifice.

And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment. "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) – to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative（故事）of upward mobility so your children can do the same.

I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    It used to be a matter of fact when Peter Pan – a character from James Matthew Barrie'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 ranged 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 (疏导) their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes referred 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 entertainment.

    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 pursuing “the thrills (刺激) of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times.u “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 (个性).

    “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 (品牌宣传词) of the UK fashion brand KIDULT: “Growing old is mandatory (强制性的), but growing up is optional.”

    The world we live in gets more mechanized every year. Some countries which were mainly agricultural a hundred years ago have now become industrial. New factories and towns have been built on good agricultural land. There are now fewer farms to serve a much greater population, so these farms must be more efficient in order to produce as much food as possible. There is no place in the modern agricultural world for the inefficient farmer. Unfortunately, many of the picturesque aspects of farming are disappearing in the search for efficiency. The more tractors are used, the fewer horses are needed. Everyone agrees that horses are far more pleasant to look at than tractors. But they are less efficient. Cows are usually milked by machinery nowadays, and even pigs are fed automatically. There is not much art or poetry on the modern farm, and the old traditional idea of a farm as a slow, peaceful, romantic place is totally wrong nowadays.

    The modern farmer has to be a mechanic, a scientist, an accountant and a gambler. The more mechanized farming becomes, the more expert the farmer has to be. He must understand what machinery is necessary for his kind of farm, and he must know how to use it efficiently. He must also understand the new technical advances in agriculture, and how to use chemical and synthetic products to improve his crops. The more workers a farmer employs, the more he must know about the problems of wages and taxes. As in any other industry, most modern farmers find it necessary to employ office staff to deal with these. But although he has more modern equipments and far more scientific aids than his grandfather had, the farmer is still dependent upon the weather. As he can never be sure what the weather will do, he must be prepared to take risks, and face the possibility of losing everything.

    You're out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.

    Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter's choice of words, to how they carry themselves while taking orders, to the billl's total.

Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.

    "Studies before have shown that mimicry (模仿)brings into positive feelings for the mimicker, "wrote Rick van Baaren, a social psychology professor. "These studies show that people who are being mimicked become more generous toward the person who mimicks.

    So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as, "Coming up!" Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their takehome pay. The results were clear-it pays to mimic your customer. The copycat (模仿者)waiters earned almost double the amount of tips to the other group.

    Leonard Green and Joel Myerson, psychologists at Washington University in St Louis, found the generosity of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers' bills went up. In fact, tip percentages appear to plateau (稳定期)when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.

    "That's also a point of tipping," Green says. "You have to give a little extra to the cabdriver for being there to pick you up and something to the waiter for being there to serve you. If they weren't there, you'd never get any service. So part of the idea of a tip is for just being there."
