In the old days, children were familiar with birth and death as part of life. Now this is perhaps the first generation of American youngsters who have never been close by during of the birth a baby and have never experienced the death of a family member.

    Nowadays when people grow old, we often send them to nursing homes. When they get sick, we send them to a hospital, where children are forbidden to visit terminally （晚期的）in patients— even when those patients are their parents. This deprives（剥夺）the dying patient of family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience.

    Some of my colleagues and I once interviewed and followed about 500 terminally in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential（潜在的）outcome.

    It is important for family members, and doctors and nurses to understand these patients' communication in order to truly understand their needs, fears and fantasies （幻想）. Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their great need to be informed, to be kept up —to —date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to cope with the coming of detach and finally to reach a true stage of acceptance before death.

    It was a hot day, and my brother Walt and I had decided that the only way to survive it would be to go swimming in a deep swimming hole across Mr. Blickez's Pasture（牧场）and through some woods.

    The only problem with our plan was that this pasture was guarded by a huge, mean Hereford bull（公牛）. Mr. Blickez had told us that Elsie was the meanest bull in the town, maybe even in the county, and we believed him. But the hotter it got, the more we thought there was something fishy about his words. For one thing, we remembered Mr. Blickez liked telling tall tales; for another, Elsie seemed like a strange name for a bull.

    Finally, I talked Mom into asking permission for us to walk through the pasture, but then another problem surfaced. Mom said she would talk to Mr. Blickez if we would take our cousin Joanie along with us. Joanie was almost two years older than me and a head taller. If her teasing ever got around my grade school, it would be all over for me. In fact, I still had a headache from a quarrel with her that morning. “I'm not going swimming with that silly girl cousin,” I told my mom.

    “Either Joanie goes with, or you stay home alone,” Mom said in her serious tone（语气）. I gave in and we set out. On your way across the pasture, Walt yelled suddenly. Elsie had approached him quietly and was licking（舔）his back. Joanie and I dove under the wire fence, but while I was on the ground I looked up and saw that Elsie wasn't a big mean bull after all. She was going to keep licking my brother's back as long as he stood still.

    We had many good days growing up and visiting our secret swimming hole guarded by the so-called “big mean bull”. And as it turned out, for a girl cousin, Joanie hasn't been too bad. She's been one of my best friends over the years.

    Camping is a good way to spend time along with your kids and to show them how wonderful nature can be. Through camping, children can discover new things about nature, such as flowers, birds, and other small animals. Camping gives kids time to get away from all the electronics (电子) of today's culture. So it is necessary to plan exciting and enjoyable family camping trips with your children while they are young.

    When planning your family camping trip, consider the activities your kids like: games, hiking, swimming, boating, bicycling, etc. Select a camping place that has some of the activities the kids are interested in. Meal planning is an important part of your camping trip. Plan the meals together, and kids love to choose what they want to eat.

    When starting to pack for your trip, let the kids pack their own items (物品) . Each person should have his/her own sleeping bag with a luggage (行李) bag to put it in. Personal items should be packed with their sleeping bags. Encourage the kids to put their items in a certain place and always return it when they have finished using it.

    When you have arrived at your campsite, make all the camping activities a family activity, which will help children to realize how important team-work is. Everyone can have his/her own job sitting up the campsite. Meal time can be a fun time. So let the older ones help with the cooking on your outdoor camping stove while the younger ones get the picnic table ready.

    Listed below are the stories of women you may not know about, but definitely should.

    Hedy Lamarr

    Hedy Lamarr starred in many films. But her film career is far from her only noteworthy achievement; she was also a brilliant inventor. In 1942, she and composer George Antheil received a patent（专利）for a device that could change radio signal frequencies. The purpose of the technology was to keep military enemies from figuring out messages. But it did more than that - it laid a foundation for the wireless technology we use today.

    Maria Sibylla Merian

    Today, children can happily explain how a caterpillar（毛虫） tums into a butterfly. But there was a time when no one knew this. Until the 1670s, scientists thought that caterpillars and butterflies were two totally different creatures. Thanks to Maria, we know the truth about these beautiful winged insects. Fascinated by insects, she began collecting, studying and drawing them as a child. It was through her study of caterpillars that she discovered the truth about their life cycles. She published two volumes of naturalist research, which provide major contributions to the field of entomology（昆虫学）.

    Ada Lovelace

    Ada Lovelace, the daughter of celebrated British poet Lord Byron, wasn't a poet herself but the world's first computer programmer. We think of computers as a recent invention, but people were toying with the idea of "computing machines" in the mid – 19th century when Lovelace was alive. Lovelace's mathematical genius was apparent at a young age and caught the attention of Cambridge professor Charles Babbage, who was working to design early computing machines that would be able to quickly solve math problems. Lovelace wrote some suggestions as to how to program the machines to work out numbers.

    In addition to designing this early computer program, she was also the first to surest that these computers might be able to do more than compute. She imagined them doing almost everything, from producing images to composing music.

    Doctors say you had better use it before you lose it. The more you sit each day, the more chance you have of getting sick.

    Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.

    Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from New South Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.

    The study also showed that exercising every morning for 30minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.

    Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.

In life, once on a path, we tend to follow it, for better or worse. What's sad is that even if it's the latter, we often accept it anyway because we are so used to the way things are that we don't even recognize that they could be different. This is a phenomenon psychologist call functional fixedness.

This classic experiment will give you an idea of how it works and a sense of whether you may have fallen into the same trap: People are given a box of tacks (大头钉) and some matches and asked to find a way to attach a candle to a wall so that it burns properly.

Typically, the subjects try tacking the candle to the wall or lighting it to fix it with melted wax. The psychologists had, of course, arranged it so that neither of these obvious approaches would work. The tacks are too short, and the paraffin (石蜡) doesn't stick to the wall. So how can you complete the task? The successful technique is to use the tack box as a candle-holder. You empty it, tack it to the wall. and stand the candle inside it. To think of that, you have to look beyond the box's usual role as a receptacle just for tacks and re-imagine it serving an entirely new purpose. That is difficult because we all suffer to one degree or another from functional fixedness.

The inability to think in new ways affects people in every corner of society. The political theorist Hannah Arendt coined the phrase" frozen thoughts" to describe deeply held ideas that we no longer question but should. In Arendt's eyes, the self- content reliance on such accepted "truths" also made people blind to ideas that didn't fit their worldview, even when there was plenty of evidence for them.

Frozen thinking has nothing to do with intelligence. She said," It can be found in highly intelligent people."
