An artist in Oakland, California isusing his skills to help the homeless. Greg Kloehn builds very small shelters that make life on the streets a little more comfortable. The structures offer the homeless some safety and protection from bad weather. Each little house also has wheels on the bottom so it can go wherever its owner goes.

    Greg Kloehn has given away at least 20 tiny houses. Several are on the roadside near an active railroad. On a recentday, Mr. Kloehn stops at one to visit Oscar Young. The two men hug. Inside his little shelter Mr. Young gets relief from cold nights on the streets. Mr. Kloehn also visits Sweet-Pea, another friend who also lives in one of the little homes the artist built. She says it keeps her safe and protects herbelongings.

    In the mornings, Mr. Kloehn searches the streets for building materials. He gathers what he can and takes it to his studio. There, he puts the houses together. Empty coffee bags become roofmaterial. A washing machine door and refrigerator part become windows. Nails, screws and the sticky glue hold all the pieces together. The artist also attaches a small electrical device to the house. The device is powered by the sun.

    Some of the people living on the streets once had normal houses of their own. But some of the people say they have learned to live with less and they are thankful to that man.

    Mr. Kloehn says his work is not a social project. He says he is just someone using his skills to help his homeless neighbors.

    With all of the wonderful things life brings us, it also brings us stress. It is for this reason that I am an active supporter of mental health days.

    Although it's never good to ignore(忽视) responsibilities, sometimes it is good to unplug(拔除) from the world for a day. We eat healthy and stay active to keep us from getting sick, but sometimes we forget to care for our minds. Our minds and bodies are connected, and when only one is being cared for, the other may be suffering. It is important to try to combine self care with our lives and spend time on activities we enjoy. This helps relieve stress on a daily day.

    So, what do you do on a mental health day? The answer is anything you want. Growing up, my brother and I were allowed a few mental health days a year. We would stay home from school and relax. For him, it was playing games on the computer, while my days were spent reading or watching TV. My mental health days now include picking things up around my apartment, cooking a tasty meal, and then reading for a few hours. I completely shut myself off from work or school. To me, this is relaxing. Organize the clutter(凌乱的东西) that piles up during the week, cook the meals I don't have time to cook, and read the books that I've bought but don't have time to read.

    A mental health day is great, but only if it's supplemented(增补) with self care through the week. From my experience, if self care is not regularly provided in your week, taking a mental health day is just going to stress you out even more. But when it's needed, try hard to recognize that and take care of yourself. It will help keep you happy and healthy. A mental health day is not a day to avoid life, it is a day to recoup(恢复).

    Youth football team members rescued more than two weeks after sudden flooding trapped them in a cave in Thailand are now being well looked after at a hospital in the northern city of Chiang Rai. In addition to treating the boys for potential body fluid loss, inadequate nutrition and lack of oxygen, their doctors also plan to closely monitor them for symptoms of diseases that may have been infected by animals living in the cave.

    "The next step is to make sure those kids and their families are safe, because living in a cave provides a different environment, which might contain animals that could transmit…disease," said the local hospital. The boys and their family members have been told to watch for symptoms such as headache, nausea(反胃), muscle pain or difficulty breathing, the reports added.

    Yet based on the location where the boys were trapped—more than four kilometers from the cave complex's main entrance, past some fully submerged passages—and the fact they have been swimming out wearing full scuba face masks, it seems unlikely that they were living with bats in the cave or breathed in bat-associated bacteria during their rescue, several infectious disease experts said. "It's hard to imagine bats got that deep into the cave because of all those narrow passageways, but it is possible," says Ian Lipkin, an animal expert and professor at the Mailman School of Public Health at Columbia University. "It's unlikely that there would be many animals in there," notes Jonathan Epstein, a doctor at EcoHealth Alliance, a nonprofit organization that studies diseases and how to prevent them. Bats typically like to rest in areas they can easily enter and exit, not in places that fully flood, he adds.

    Bats in Thailand have been linked with a wide range of viruses that are similar to severe acute respiratory syndrome (SARS)—Lipkin says. But it seems more likely the boys would have been exposed to infection-causing bacteria when they swam through the dirty water with cuts and scrapes. "If you are trying to prioritize issues with respect to health care for these kids, number one would be psychological damage and second will be bacterial infections from the cuts and scrapes they may have encountered." Lipkin says.

    On the last day before Christmas, I hurried to the supermarket to buy Christmas gifts. In the supermarket, I noticed a little boy, holding a doll and looking so sad. He turned to the old woman next to him, “Granny, are you sure I don't have enough money?” The old lady replied, “You know we don't have enough money to buy this doll, my dear.” Then she left for something else and the boy still stood there.

    Finally, I went to the boy and asked him who he wanted to give this doll to. “It is the doll that my sister wanted so much for this Christmas. She was so sure that Father Christmas would bring it to her.”

    I told him that maybe Father Christmas will bring it to her. But he replied to me sadly, “No, Father Christmas cannot bring it to her where she is now. I have to give the doll to my mother so that she can give it to her when she goes there. My sister has gone to be with God. Daddy says that Mummy will also go to see God very soon, so I thought that she could bring the doll with her to give it to my sister.”

    Hearing this, I quickly reached into my wallet and took a few notes and said to the boy, “What if we checked again, just in case if you have enough money?”

    “OK,” he said, “I hope that I have enough.”

    I added some of my money to his without his seeing and we started to count it. There was enough for the doll.

    The little boy said, “Thank God for giving me enough money.”

    Then he looked at me and added, “I prayed to God yesterday before I slept to make sure I have enough money to buy this doll. He heard me.”

    There are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.

    But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little in school. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may have many problems at their schools.

    You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, it may not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.

Dear editor(编辑),

    Can't your newspaper do something about the custom (习惯) of hitchhiking?

    A short time ago, on a car travel I counted at least 50 people standing beside the road, asking for rides. Many of them were young women.

    Don't they understand how dangerous it is to get into the car driven by a stranger? How much do they know about the driver? Is he a good driver or not? They know nothing!

    Many of these young hitchhikers may come from good families. Don't their parents teach them anything about the world? I always taught my children not to talk to strangers. I never let them take rides from people they didn't know.

    Isn't there enough crime (犯罪) today without asking for trouble by hitchhiking? On the other hand, hitchhiking may bring some traffic trouble. Don't you think what I said is true?
