Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $ 16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip.

    But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service.

    Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least 15% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $ 2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, “In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off.”

    I was a shy girl. I didn't even like to answer the telephone for fear I'd have to talk to somebody I didn't know. I enjoyed the loneliness of exploring nature. However, at school I had to spend all day in the company of others. My escape was reading. I spent a lot of time studying and was rewarded with good grades. My only failure was Spanish—I'd get all. As on my written work and tests, but Ds and Fs on the spoken part.

    Eventually I went to college. During my third year of college, I had enough of being shy and determined to change my outlook and behavior. One day while at school, I noticed an advertisement for positions on the local classical music radio station. I had grown up listening to classical music, and I could easily pronounce names such as Tchaikovsky, Albinoni, and Chopin.

    I had absolutely no background in radio, and absolutely no hope of getting the job. The idea of talking to thousands of listeners in “radio land” terrified me. However, I luckily survived the interview. I was given brief descriptions of symphonies（交响乐）and a public service announcement to read, and a list of composers' names to pronounce. It wasn't hard for me. I left the recording session（录音时段）with a sense of relief and a sense of accomplishment. About two weeks later I actually landed the job. It was a challenging job, but I grew to enjoy it greatly. I began to feel comfortable talking to people.

    Although I now spend many hours each week talking with people, I'm still basically a quiet person. Perhaps it is my soft voice and my quiet nature that helps draw people out as they respond to my questions as I interview them. My former shyness is a fortune, as I can relate to people who feel discomfortable when they talk to newspaper reporters. I still enjoy moments of loneliness and the peace found in nature. But I'm also glad I decided to make a change in my life that has opened many doors and opportunities that I never knew existed.

    The end of the school year is in sight — Christmas cards, candy canes and of course, end of year reports.

    While most parents welcome an assessment of their kids' performance, they do not expect their own input to be evaluated. But a school in the UK is changing that. As well as assessing their students, they are dishing out grades to mums and dads. Parents that are really involved in their kid's education are rewarded with an A, and parents that haven't done their bit get a disappointing D.

    The school, Greasley Beauvale Primary in Nottinghamshire, uses criteria such as whether mums and dads have attended school events such as plays and parent-teacher conferences to decide on the grade. The school's principal, Donna Chambers, said that the scheme (方案)had been well received.

    “There were some critics, but my response was 'well, it can't do any harm'. Between 15 percent and 20 percent of parents started out in the lower categories but now that has been reduced to just two percent,” she explained.

    Chambers hopes that the scheme will help motivate parental involvement. “The system is important because you have got to get the parents on board from day one. That one hour initial conversation saying they could improve will pay dividends for the rest of that child's academic life”, she said.

    But while the scheme may be well-intentioned, it is likely to be connected with parent shaming. There are lots of reasons why some mums and dads might not be involved in school activities such as work commitments, looking after younger children or caring for elderly relatives.

    And of course, being involved in your kid's education doesn't begin and end at school. There is a lot that goes on behind the scenes from helping with homework to keeping uniforms freshly laundered. And what about all the parents who stayed up sewing special costumes at the last minute? Surely that earns a gold star instead of a grade!

    Wong Fuk-wing, a Hong Kong volunteer at an orphanage (孤儿院) in Yushu, was killed in the earthquake when he was trying to save others on April 14, 2010.

    Wong managed to run safely out of the building with some children when the first quake happened at 7:50 am on April 14, but he went back inside to rescue three other children and three teachers inside, although he knew the danger of aftershocks (余震).

    At 10 am, all the children and one of the teachers were saved. However, Wong was buried under the fallen building and died. The other two teachers were still waiting to be rescued.

    46-year-old Wong was a truck driver, who often said he could only give his efforts to charity instead of money, as he did not earn a lot. His tragic (悲剧的) end touched the hearts of many people both in Hong Kong and on the mainland.

    Wong began volunteering in 2002. In 2003, Wong was told by the doctor he got serious illness, which gave him a great blow. However, the illness did not deter the warm-hearted man. When the earthquake struck Wenchuan is Sichuan Province in 2008, Wong rushed to the disaster area of Shifang to offer his help though his family did not want him to go.

    In fact, Qinghai is a place Wong had often visited since 2006. As a volunteer, he gave out medicine and clothing to the orphanage there. No one could expect that Wong would die helping others.

    Hong Kong Chief Secretary Henry Tang Ying-yen said he had “the highest respect” for the hero who gave his life for others. “What he did has shown the Hong Kong spirit.” The citizens of Hong Kong called him “the pride of Hong Kong's people” and people on the mainland have also praised him as “a true hero”.

    It is not only praise or punishment that determines a child's level of confidence. There are some other important ways we shape our kids—particularly by giving instructions and commands in a negative or positive choice of words. For example, we can say to a child "Don't run into traffic!" or "Stay on the footpath close to me." In using the latter, you will be helping your kids to think and act positively, and to feel competent in a wide range of situation, because they know what to do, and aren't scaring themselves about what not to do.

    Actually, it is all in the way the human mind works. What we think, we automatically rehearse. For example, if someone offered you a million dollars not to think of a blue monkey for two minutes, you wouldn't be able to do it. When a child is told "Don't fall off the tree," he will think of two things: "don't" and "fall off the tree". That is, he will automatically create the picture of falling off the tree in his mind. A child who is vividly imagining falling off the tree is much more likely to fall off. So it is far better to use "Hold on to the tree carefully."

    Clearly, positive instructions help kids to understand the right way to do things. Kids do not always know how to be safe, or how to react to the warning of the danger in negative words. So parents should make their commands positive. "Sam, hold on firm to the side of the boat" is much more useful than "Don't you dare to fall out of the boat?" or worse still "How do you think I'll feel if you drown?" The changes are small but difference is obvious.

    Children learn how to guide and organize themselves from the way we guide them with our words, so it pays to be positive.

    Wellington: Huawei has started a rugby-themed media campaign in a bid to win over New Zealand's public after the country's security agency blocked the Chinese technology giant's equipment from being used in a nationwide Internet network.

    "5G without Huawei is like rugby without New Zealand," ads in New Zealand's two largest newspapers read alongside a photo of players competing in a ball. Large posters also appeal to the country's love of the sport. In November, New Zealand's Government Communications Security Department (GCSD) told Spark it couldn't use equipment from Huawei-the world's largest telecommunication equipment company—in the building of its 5G network because an unspecific "significant network security risk was identified". Spark is now in the process of seeing if it can make changes to prevent those risks, although GCSD has declined to publicly say how that would happen.

    Huawei's newspaper ad goes on to argue the decision would mean less advanced technology and higher prices for New Zealand customers. The ads come after the company last month publicly offered to only use New Zealand, rather than Chinese, staff to build the network—in a bid to ease fears—and called for an urgent meeting with the government, denying (否认) there had been any wrongdoing.

    Western spy agencies have increasingly raised security concerns about Huawei—China's largest telecommunications company-over what they say are possible links to the Chinese government, with the United States reportedly pressing Five Eyes intelligence network allies (同盟国) to avoid the company. Australia and Canada were the first countries to ban Huawei from a building of 5G networks.

The company has repeatedly denied accusations.

    New Zealand's top politicians have repeatedly denied the GCSD decision was influenced by other Western powers and say it's about the particular technology being suggested, not China. They have also denied suggestions New Zealand's diplomatic ties with China have been tense over the decision, with the official promotion of a major China—New Zealand tourism project now postponed.
