“Don't you have any toys you want to share?” I asked my son during our church's Christmas toy drive. “What about all those things in your closet you haven't used in years?”

    "I don't have anything,” he said. “We're so poor.”

    We're only “poor” because we refuse to buy him the phone he wants for Christmas, which would also require a monthly texting charge.

    “You're not so poor you have nothing to give,” I found myself saying to him, a phrase my mother often used on me.

    At work the next day, one of my students said, “I didn't spell your name right,” as she handed me a Christmas gift—a box of chocolates. No wonder she hadn't spelled it right—I had only worked at the center for a couple of months, and my name is not easy to pronounce, even in English, which is this woman's second language.

    I hadn't expected a gift—I worked at an adult education center, where we dealt with people who struggle economically. When I was hired, my boss told me she tries to keep snacks around the center and cooks “stone soup” once a week, where whoever can bring something in does, because “You will hear growling bellies here. They give their food to the children before they themselves eat.”

    And yet these people, so grateful for a second chance at getting an education, unable to sometimes even afford the gas money to come in, manage to do something for us nearly every week. Some bring in food; others do chores around the center. They help and encourage one another, and us. They give what they are able to give.

    Having friends may well keep you healthier and help you deal with stress better. Some studies show that people with close friends have a greater ability to fight disease than people who are alone.

    Place friendship in the first place. Find the time to be with friends even if it means letting the lawn go unmoved or the dishes unwashed for a while. When you can't get together, use the phone to keep in touch.

    Open up to close friends. Keeping a deep friendship requires a level of “heartfelt” intimacy (亲密). Don't be afraid to express your inner fears and disappointments. Listen to your friends when they have problems, but offer advice only when it's wanted. Help raise friends' self-esteem when they are sad about a job loss, or other such events.

    Have different friends for different activities, such as going to the movies, singing in a choir, and joining in a bowling league.

    Don't wait for a friend to ask for helps. When a friend has the flu, offer to go to the store or drive his or her children to their after-school activities.

    Never take a friendship for granted. Like a good marriage, friendship needs care and patience. Become a joiner. Find a group that matches your interests.

    Talk to strangers. Conversations started in museums, laundry rooms, or bookstores can lead to firm friendship.

    Enroll in an adult-education course. A classroom is an ideal place to meet others with similar interests.

    Body language is one of the most powerful means of communication, often even more powerful than spoken language. It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying.

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't sit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse(噘嘴) your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased.

    Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust (厌恶) and fear to come through.

    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 b friendships and a b 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.

    Who is the most beautiful woman in the world? This question can't be answered as quickly as the magic mirror I answers the queen in Snow White. However, PEOPLE, a US magazine has been trying to answer that question since 1990. The magazine has its own Most Beautiful Woman every year. And last year it announced its pick for “World's Most Beautiful Woman” of 2017. It was Julia Roberts, who had won the title five times. “I am very happy,” said the Hollywood star. “I think I'm now peaking.”

    Roberts has been named “Most Beautiful” more times than anyone else. She first appeared on the magazine in 1991 at the age of 23. Roberts is perhaps not the perfect choice in all people's mind. There are so many beautiful ladies in different fields after all. But PEOPLE has its own reasons, and it's not just about her looks. Julia has never looked better. Her beauty also lies in her self-confidence and good humour. It lies in her ability to develop while keeping the best parts of herself. It lies in her talent for creating characters and telling stories that take us to new places. It lies in her beautiful smiles.

    In Julia's view, the most important secret for beauty is being happy! “Beauty is about your spirit. Be happy and live the life you want to live. That's the key to looking your best,” said Julia.

    Every year, 1.5 million kids around the world die as a result of not getting vaccines (疫苗). This is partly because transporting and storing medicines can be a huge challenge in some countries.

    Anurudh Ganesan, 17, knows this firsthand. When he was a baby in India, his grandparents carried him 10 miles to a health clinic in a remote village to receive a vaccine. But by the time they arrived, the vaccines were no longer usable because they had been overheated.

    Vaccines, Anurudh later learned, must be kept cool to stay effective. But refrigerating them requires electricity or ice – precious resources that many developing countries lack.

    Although Anurudh eventually received the vaccine he needed, his experience as a baby and the sad reality that so many other children aren't as lucky motivated him to take action. The high school student invented Vaxxwagon, a portable vaccine-carrying device that generates its own power to keep lifesaving medicines cool as they're delivered to remote areas around the world.

    Anurudh first got his idea for Vaxxwagon in 2014. He read several textbooks to learn everything he could about refrigeration, and then he did research online to learn more about vaccines. Rather than relying on electricity or ice, Anurudh figured out a way to use wheels to power a refrigeration system for about eight hours. The entire rechargeable cooling system can be pulled to areas in need of vaccines by a bicycle, a car, or an animal. Eventually, Anurudh took his design to professors at Johns Hopkins University for advice. Not only did they confirm Vaxxwagon could work, but they offered him funding to help build it.

    Anurudh was rewarded with the 2015 Google Science Fair LEGO Education Builder Award for his invention. Anurudh says his final goal is to start selling Vaxxwagon to relief organizations, so it can be used to help people around the world.

Anurudh, who plans to pursue engineering degree in college, says, “Don't give up on your ideas. But always try to help others with your projects. That's the point of engineering – to help people.”
