We have two daughters: Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang. Mommy would introduce them to the guests, and then they would take the guests' coats upstairs and put them on the bed in the second bedroom.

    The guests arrived. I introduced my two daughters to each of them. The adults were nice and kind and said how lucky we were to have such good kids.

    Each of the guests made a particular fuss over Kelly, the younger one, admiring her dress, her hair and her smile. They said she was a remarkable girl to be carrying coats upstairs at her age.

    I thought to myself that we adults usually make a big "to do" over the younger one because she's the one who seems more easily to be hurt. We do it with the best of intentions.

    But we seldom think of how it might affect the other child. I was a little worried that Kristen would feel she was being outshone. I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying.

    I said, "What are you doing, my dear?"

    She turned to me with a sad expression and said, "Mommy, why don't people like me the way they like my sister? Is it because I'm not pretty? Is that why they don't say nice things about me as much?"

    I tried to explain to her, kissing and hugging her to make her feel better.

    Now, whenever I visit a friend's home, I make it a point to speak to the elder child first.

    A new study of 8,000 young people in the journal of Health and Social Behavior shows that although love can make adults live healthily and happily，it is a bad thing for young people. Puppy love（早恋）may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

    The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to their parents.

    Dr Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

    Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons，they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity(成熟) gives us a chance to avoid its bad side effects.

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways．For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand，are already part of a language community. Learning a new language means becoming part of another language community, and adults seldom get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    Research has shown that children who learn a new language when they are very young will not be likely to have a “foreign” accent when speaking a different language. Some scientists also believe that it can take up to 10,000 hours of study to master a new language. This can be difficult for adults to achieve, but young children can accumulate(积累) those hours over several years as they grow up.

    When young children learn a new language, they come to see multiple languages as a “normal” part of society. This mindset (思维模式) helps them learn a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    PHILADELPHIA-The thumb of a Terracotta Warrior was stolen by a member of the public in Philadelphia, where the statue is on display. The cultural relics authority of Northwest China's Shaanxi province will send conservationists（保护工作者）to repair a Terracotta Warrior that had its thumb stolen by a member of the public while on display at a Philadelphia museum.

    US departments that are involved should guarantee the safety of the relics on display, and parties concerned will be held legally accountable, the provincial cultural heritage department said on Sunday.

The statue of a cavalryman（骑）, which dates back to at least 209 BC, is one of10

    Chinese Terracotta Warrior statues now on display at the Franklin Institute in Pennsylvania.

    Since 2009, Wang's team has restored more than 100 of the Terracotta Warriors. According to the Stolen（Lost）Cultural Relics Information Publishing Platform of China, which went online late last year, up to 60 percent of cases of theft have occurred in museums and historical relics institutions. However, most cases occurred in the 1980s and 1990s. As security technology developed in recent years, it has become more difficult to steal a cultural relic from a museum in China, according to the publishing platform.

    Chen Shiqu, deputy head of the Criminal Investigation Department at the Ministry of Public Security, said during a previous interview that the prices of cultural relics have risen in recent years, leading to more thefts by using upgraded technology.

    "Some criminals are equipped with high-tech tools that can make a tunnel very quickly to steal and transport the cultural relics," he said.  "China will continue to complete the mechanism for fighting against and preventing relies thefts. We will crack down on（打击）the whole market chain, including the trading of the relics and organized thefts. All involved offenders will face criminal liability."

    Meanwhile, US authorities said Michael Rohans, 24, from the US state of Delaware was arrested in connection with the theft and has been released on $15, C00 bail（保释金）, on the condition that he surrender his passport, consent to drug testing and refrain from leaving the country before trial. Museum staff members noticed the missing thumb on Jan 8, and a special agent from the FBI's Art Crime Team tracked down Rohana days later.

    With the New Year weeks approaching, you're looking forward to watching the splendid fireworks shows that will welcome 2019 worldwide. Unfortunately, visually impaired and blind people can't experience this joyful celebration. That may change soon thanks to Feeling Fireworks, a fireworks experience invented by the Disney Research Lab in Switzerland.

    To experience the show, users stand before a large flexible screen, place their hands at the base of the screen and move them around to feel the fireworks. Alternatively, their hands can be situated in the center of the screen, where the initial explosions happen, and then moved across to explore other fireworks.

    As the fireworks begin to explode, five nozzles (喷嘴) at the back of the screen start to shoot water, creating movement of water imitating the show. One specializes in the "blooming flower effect", another reproduces the "crackle" effect, and the rest take care of rockets and explosions. A computer controls the timing, and Feeling Fireworks allows users to experience fireworks similar to those in the sky.

    Paul Beardsley, who led the research team, says, "We want blind, visually impaired, and sighted people to all try Feeling Fireworks, and to have a shared and enjoyable memory of a fireworks evening." And the screen displaying the vivid images created by water makes it fun for everyone.

    The low-cost technology is still in its early stage, with only a 66 percent success rate. However, the team plans to continue improving the experience and believes the day when everyone will be able to enjoy the thrill of fireworks shows is not far. When ready, Feeling Fireworks will initially be available only at the Disney theme parks, and then hopefully, at fireworks shows worldwide.
