Nine years ago, after Leo had died, people said to me. "I never knew he was your stepfather." You see, I never called him that. At first, he was no one special in my life. Then he became my friend. In time, I felt he was also my father.

    Leo married my mother when I was eleven. Two years later we moved into a house in a new suburban development, where we put down roots. At first our lawn was just a mud with wild grass, but Leo saw bright possibilities. "We'll plant trees there to give us shade as well as some flowers," he said. And just these little touches made our house different from all the others. More important, a real family was forming. Leo was becoming a full-time parent, and I was learning what it meant to have a father.

    Weekday mornings when the weather was bad, Leo often drove me to school. Having a father drop you off may have been something my classmates took for granted, but I always thought it was wonderful. Saturday mornings, we went to the hardware (计算机硬件) shop, then stepped into the five-and-ten, buying a sports magazine or something else. Some people might think that doing shopping together is nothing special, but I, who had ever before spent my childhood watching other families do their everyday activities, experienced them now with extreme delight. Looking back, I realized that Leo gave me what I needed most—the experience of doing ordinary things together as a family.

    Soon after we moved to the suburbs, one of our new neighbors introduced herself to me. She had already met my mother and Leo. "You know," she said, "you look just like your father." I knew she was just making a conversation--but even so... "Thank you", I said. Why tell her anything different?

    Every so often, mankind comes up with really good inventions that have changed our daily lives. However, the U.S. Patent Office has issued over 7. 5 million patents, and not all of them are quite so celebrated. Some good, some bad, and some crazy! The following lists some of the more unusual ideas that have come along.

    Snake Leash

    In 2002, a patent was issued for a snake-walking leash. There are at least two major problems with this idea.  1) Dog leashes fit securely between the head and shoulders. A snake does not have shoulders; so it might slither away. 2) Dogs are OK for public places because they are social animals, and people like them. Snakes are not OK for public places because they are not social, and some people are terrified of them.

    Stadium Helmet

    Americans are known for our love of sports. Unfortunately, good tickets to games are expensive, and some fans have to sit in the nosebleed sections. This invention, patented in 2000, is designed for these fans.  Featuring a built-in radio, binoculars(望远镜) , a cooling fan,  and a helmet for falling litter, this design transforms the stadium experience.

    Bacon Alarm Clock

    When you think about it, waking to the dreadful, blaring noise of an alarm clock is a terrible way to start the day. However; this clock could change that. You simply put a piece of frozen bacon in the alarm clock, set the alarm, and go to sleep. The clock gently wakes you up with the mouthwatering smell of bacon the next morning, just like waking up on a Sunday morning to the smell of Mom cooking breakfast. Who said there's no time to eat breakfast?

    Toilet Lock

    In 1969, a patent was issued for a really bad idea – the toilet seat lock. First of all, fishing for your keys when you have to go seems very unpleasant. Then there is the possibility of losing the key altogether. What about guests? Just think that you would have to ask permission for the bathroom. Of course, there is the ultimate question: Why would you lock it in the first place?

    Humana Bird Feeder

    People have always admired the gracefulness and beauty of birds, and bird watching is a popular hobby. Unfortunately, getting up close and personal is a challenge. That is, until now.  In 1999, a patent was issued for a helmet with birdfeeders attached to it. Although there may be a design flaw (缺陷) (turning the head to see the birds would probably frighten them), this invention could change the way of bird watching.

    Like many children, young Lotte Reiniger was crazy about movies, which at the time were a completely new invention. She taught herself how to cut paper silhouettes（剪影）, of people, animals, and objects. I could cut silhouettes almost as soon as I could manage to hold a pair of scissors, Reiniger said. “I could paint, too, and read...But everybody was surprised at the scissor cuts”

    At first, Reiniger wanted to be an actress, but her skill at making silhouettes drew the attention of the German film industry. Before 1927, films were silent. To help the audience understand the film, title cards with printed text appeared during the film between scenes. Reiniger helped create title cards for films, using her silhouettes. In 1918, she was asked to provide stop-motion animation（定格动面）, in which objects are photographed（拍摄）in a series of slightly different positions and then replayed at high speed so that the objects appear to move on their own, for wooden rats（老鼠）in the movie The Pied Piper of Hamelin. It was a breakthrough that led to her own films, first short films and then, in 1926, The Adventures of Prince Achmed, the first full-length animated film.

    Although Reiniger once described herself as “a primitive（原始的）caveman artist”, her work is not simple. She carefully cut bits of card, paper, and wire, creating wonderful shapes, and then made them move and dance by hand. The black shapes were then placed on colorful backgrounds. She made more than 60 films, around 40 of which survive, all cut by her own hands. Most were based on timeless fairy tales, like Cinderella and Sleeping Beauty.

    Reiniger was truly a pioneer both in animation and for women in film-making. Though her last film came out in 1980, her style is still influential and can often be seen in today's films.

Learn to cure cancer

    A vaccine for cancer is in the works.

    Lauren Landry and Chloe Tomblin are the scientists. They look in freezers(冰柜) for bacteria to use in the research. This research has its limitations—mostly because their lab is in a high school.

    But Lauren, 16, and Chloe,17 both students are Western Reserve Academy in the US, aren't put off by the difficulties they face in their cancer immunology(免疫学) class.

    “I hope we get to the point where we can get to a vaccine and write a paper,” Lauren said.

    Both conduct research into how to engage the immune system in stopping cancer from forming.

    Though the lab is in a high school, they don't use textbooks. The aim is to conduct real cancer research, either by testing the effects of substances on cancer cells or developing vaccines to target the growth of those harmful cells.

    The idea for the class came from Robert Aguilar, who has taught at the private school for many years. Students spend the first year learning research techniques. In the second year, students swap(调换) their blue lab coats for white ones. By this stage they are well into their research projects.

    “If first-years need any help, they can feel free to ask second-year students,” Aguilar said.

    Students form groups to conduct their research. One pair of students has researched the effect of capsaicin(辣椒素) on killing cancer cells. Another has tested the effect of caffeine(咖啡因) on the growth rate of breast cancer(乳腺癌) cells.

But few students get to the point in their research of experimentation with mice, Aguilar said. Lauren and Chloe hope that they can make decent progress in their work.

    “We know they're going to be used for good,” Lauren said. “If it does or doesn't work, it still has a huge impact.”

    Aguilar teaches the students that even research that doesn't work still contributes to science in some way. He tells students that “the best part of research is failing a lot”.

    The holidays are the best time to ask the elders in your family for advice. For most people, the approaching holiday season includes more time with the extended family, including the elder generation.

    Unfortunately, older adults are often unseen in the popular media. Yet there's a big body of evidence that shows the benefits of older adults' wisdom and the value of developing communication across generations.

    First, over the course of human history, older people have played very important roles as advice-givers. Anthropological (人类学) research shows that survival in pre-literate societies was dependent on the knowledge of the oldest members.

    In recent times, most of the researches about intergenerational communication occur within formal programs, such as ones including older adults in public schools or having youth visit assisted living facilities. Also, you can apply many of the lessons of the researches to your own family gatherings.

    There is clear evidence that it is good for young people to spend time with older adults. The youth who participated in intergenerational programs showed more respect toward older adults, less anxiety, and higher self-esteem. Research also shows that interacting with younger people is good for older adults. A systematic review found that older adults who participated in intergenerational programs were likely to experience more satisfaction with their lives, higher self-esteem and fewer symptoms of depression. Interactions during intergenerational programs can be positive even when an older adult is experiencing memory or cognitive problems.

    Having children teach computer or video games to the older generations can be a fun way to spend time together. A study found that intergenerational games can help family members to bond. Another idea is to encourage the youth to ask older family members for their advice about life.

    The youth can ask older adults specific questions about the lessons they learned from their life experiences.

    The take-home message is that time with older relatives is one of the true gifts of the holiday season. Make the most of it by spending time with the older generation!

If you ask 100 people what subjects they wish they had been taught in school, there is a chance that the vast majority of them will complain about the lack of personal finance education. In my case, I did learn a bit about financing while in school — just not in the classroom. One of my earliest lessons on the basics of budgeting came from an unlikely source: the cafeteria.

My lunch budget was a set amount each week. Without a plan, it would be all too easy to blow through the budget long before meeting all expenses. Therefore, my very first budgeting lesson was to make a budget well. A bit of simple arithmetic (算术) helped me determine exactly how much money I could spend each day if I wanted to actually have lunch all week. 

Besides, my school had relatively diverse lunch offerings. You could not only get the common hot school lunch but also find many other foods of varying attractions. As far as I was concerned, what attracted me most was the ice cream. Unfortunately, I couldn't blow my daily lunch budget on ice cream. And I'd already figured out that splurging early in the week made for a rough time for the rest of the week. Hence, I learned my second important budgeting lesson: save for a goal. Because of this lesson, when Friday rolled around, I would have just enough left over for a wonderful lunch and the highly desirable ice cream. 

Nowadays, my budget is a bit more complicated than the lunch budget in the past. Although I no longer have to save my pennies for a frozen treat, budgeting my money today uses the exact same skills I learned all those years ago. Actually, whether you're budgeting for school lunches or credit card bills, the basics remain the same. And it's never too early — or too late — to learn how to make a proper budget.
