Parents who help their children with homework may actually be bringing down their school grades. Other forms of parental involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.

    The findings challenge a key principle of modern parenting where schools expect them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.

    Keith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that was consistently negative was their parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the tasks."They may either not remember the material their kids are studying now, or in some cases never learnt it themselves, but they're still offering advice."

    Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive,  about 45% negative and the rest statistically insignificant.

    Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success. "A big surprise was that Asian-American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."

    My family lived in a motel for two years. Like most families living there, we stayed in a two- bedroom suite. We were living from paycheck to paycheck, so when Christmas approached, we didn't know if we could be able to purchase gifts for our children.

    A few days before Christmas someone dropped off presents for all the kids that lived in the motel. It brought so much joy to all the children, most of whom knew that they wouldn't be receiving anything.

Five years ago, we moved out of the motel. After that, my husband and I were working hard at the Joe's Crab Shack to support our family. A few days before Christmas, I was working a “big top” and a single table. The man at my table could see that the large table was taking most of my time, but I was very patient and friendly. Between drinks and food I was able to chat with him about his family and mine. He left me $10, then walked out. About 10 minutes later, I turned around and there he was again. He gave me a hug, and put something in the side of my coat, telling me “Have a Merry Christmas”. I reached into my coat and pulled out $800.

    I was so moved by his generosity that I burst into tears. He had given me more than enough money to help my family catch up on our bills. After discussing what we should do with the money we had left over, we decided to buy presents for the families living at the motel, so we could pass on the blessing that we had received. Since then, it has been a tradition for us to give Christmas gift to the families in need.

    Last year we were able to give presents each of the 80 children at a school in our community, and throw a Christmas party for them. This year our goal is to add at least 20 children.

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.

    Spending money on time-saving services reduces stress and boosts(增进）happiness according to a new research, but shockingly, few of us do it.

    Whillans, a professor at HBS said, "Buying time helps to protect us from the stress in our lives caused by time pressure, and the feeling that we don't have enough minutes in the day to complete our tasks."

    The effect was clearest in the Canadian experiment, in which 60 working adults were given $40 to spend in two different ways. One weekend, they were told to spend the money on a material purchase—a gift for themselves. The next weekend, they were instructed to spend the $40 on anything that saved them time,  from paying the neighbor ' s kid to run errands (跑腿）to taking an Uber instead of a bus.

    "On the day they made the time-saving purchase, they felt happier, in a better mood, and lower feelings of time stress than on the day they bought a material purchase, " said Whillans.

    The biggest surprise to the researchers was how few people would spend money on time-saving services. When they asked 98 working adults how they would spend a "windfall"(意外之财) of $40, only two percent named a purchase that would save them time.

    "One reason," said Whillans, "is that we're very bad at remembering how much we hate doing certain tasks once the suffering has passed. That makes us less likely to take active steps to avoid that overburdened feeling in the future. "But another possible cause is good old-fashioned guilt." If you feel guilty about getting someone to clean your house for you, then you might get less happiness from outsourcing (外包）that task, " said Whillans, "or you might just be less likely to spend your money in that way."

    When we want to tell other people what we think, we can do it with the help of words. We can also do it in many other ways, too. Sometimes we move our heads up and down when we want to say "yes", and we shake our heads when we want to say "no". Some people can't hear or speak. They talk with the help of gestures（手势）. People from other countries often have to do it if they don't know your language.

    Here is a story. An American was once having his holiday in Italy, but he could not speak Italian. One day he went to a restaurant and sat down at a table. When the waiter came, the American opened his mouth, put his fingers in it and took them out again. In this way he wanted to say "Bring me something to eat". The waiter soon brought him a cup of tea. The American shook his head and the waiter understood that he didn't want tea. So he took it away and brought him a glass of milk. The American shook his head again. He was very hungry now and looked sad. He was just going to leave the restaurant when another man came in. When this man saw the waiter, he put his hands on his stomach(胃). In a few minutes there was a large plate of bread and meat on the table in front of him.

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: "Cinderella"(《灰姑娘》).

    "Cinderella" made more like $70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, "Anyone will find something to enjoy in it." Steven Rea of The Philadelphia Inquirer called the movie "a winning re-do." Richard Corliss of Time magazine wrote that "Disney finally got Cinderella right." Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, "This Cinderella is all dressed up with nowhere very interesting to go."

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sale. And Disney has widened its usual market for "Cinderella" products.

    There are products connected to the Disney movie targeted(面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create "Cinderella's shoes." You can buy them for about $5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince(王子).

    The makeup(化装品) company MAC quickly sold all its products connected to "Cinderella." HSN is a popular website selling clothing and objects for the home. The marketer is now also selling "Cinderella" products.

    So, is there anything left for the children, those people we think of as the traditional audience for the age-old tale? Yes, you can find toys and other children's products at the American store JC Penney. Of course, you can also visit a Disney store.
