Writing journals has been one of the most helpful things I've ever done. Through writing journals I've not only learned a lot about myself, but also removed a lot of obsessive (烦恼的) thoughts, by writing them down and considering them.

   Journals give you a place to write down your honest thoughts without being afraid of what people will think of you. There are some ideas for writing journals:

     Draw pictures

    Write poetry or short stories

    Goals: daily and long-term

    Respond to a magazine article that you are interested in

     Write about obsessive thoughts and try to find what's causing them

     A list of things you are proud of (It can always increase your confidence when you need it)

     Make a pro/con (赞成/反对) list when you're trying to make a decision: most of the time the decision will start to be clearer afterwards

   The best way to start is to decide where you want to write your journal. (Though it's called the journal, it doesn't mean you can only do it in a “journal”) . If you like the traditional style of journals, then use a notebook, blank paper or graph paper, whichever you like best. If you prefer to go digital, start a blog. You can make the blog public or private, and it's a good way to keep track of articles or pictures you find online. (You can link to them.)

   Even if you feel there's nothing for you to write about at first, you might be surprised to find that once you start, you can't stop.

    94% of 3-and 4-year-olds have been spanked(打屁股) at least once during the past year, according to one study.

    74% of mothers believe spanking is acceptable for kids ages 1 to 3, says another study.

    61% of parents take spanking as a "regular form of punishment" for young children, according to a different study.

    Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.

    There are many things that a parent can do. One thing that people have done is to spank the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong.

    One parent remembers being spanked when he was a child. His parents used a wooden spoon. When he spanked his own children with his hand, he saw that he put a red mark on his child's leg. He never did that again.

    One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing.

    Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts say that parents have the right to teach their children how to behave.

    Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child's level and taking a more child-friendly approach can help as well.

    For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.

    “A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts.

These parts are not made of steel; they are the real things — living cells, tissue, and even organs.

    Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina's Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs—from kidneys to ears.

    The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient's body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient's own cells and will not be rejected by the body's immune system.

    Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala's medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.

    So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals' chances of survival.

    We're often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald's Primary School in Chester certainly agree.

    Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note. “Sometimes they can be busy and I don't think they think they can make a difference，but if everyone does a little bit it all adds up，” she tells HuffPost UK.“ We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.” she says.“ Fish can eat the plastic and they can die，or we might even eat the fish ourselves.”

    Mr Timms，Isobel's teacher，has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly. The entire Hummingbirds class，which is made up of 9 and 10-year-old pupils，has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

    Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us. We sometimes overlook how much we can really learn from children.” he says.“ It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic，and to recycle more，and even stopping them using plastic straws.”

    Mr Timms is proud of his Hummingbirds class.“ The message that they would like to send to the world is simple stopping this isn't someone else's job，and it won't be OK if we just leave it.”

    Some people believe that international sport creates goodwill between the nations and that if countries play games together they will learn to live together. Others say that the opposite is true: that international contests encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both arguments, but in recent years the Olympic Games have done little to support the view that sports encourage international brotherhood. Not only was there the incident of tragedy involving murder of athletes, but the Games were also ruined by lesser incidents caused principally by minor national contests.

    One country received its second-place medals with visible anger after the hockey final. There had been noisy scenes at the end of the hockey match, the losers objecting to the final decisions. They were convinced that one of their goals should not have been disallowed and that their opponents' victory was unfair. Their manager was in a rage when he said; "This isn't hockey. Hockey and the International Hockey Federation are finished." The president of the Federation said later that such behavior could result in the suspension of the team for at least three years.

    The American basketball team announced that they would not yield first place to Russia, after a disputable end to their contest. The game had ended in disorder. It was thought at first that the United States had won by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into the basket. It was the first time the US had ever lost an Olympic basketball match. An appeal jury（评审委员会）debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.

    Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals or in non-national teams, might be too much to hope for. But in present organization of Olympics there is far too much that encourages aggressive patriotism（爱国主义）.

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.
