"Dad," I say one day …..take a trip. Why don't you fly and meet me?"

    My father had just reired……….. His job filled his day, his thought, his life. While he woke up and took a warm shower, I screamed under a freezing waterfall Peru. While he tied a tie and put on the same Swiss watch, I rowed a boat across Lake of the Ozarks.

    My father sees me drfting aimlessly, nothing to show for my 33 years but a passport full of funny stamps. He wants me to settle down, but now I want him to find an adventure.

    He agrees to travel with me through the national parks. We meet four weeks later in Rapid City.

" What is our first stop?" asks my father.

"What time is it?"

"Still don't have a watch?"

    Less than an hour away is Mount Rushmore. As he stares up at the four Presidents carved in granite(), his mouth and eyes open slowly, like those of little boy.

"Unbelievable," he says, "How was this done?"

    A film in the information center shows sculptor Gutzon Borglum devoted 14 years to the sculpture and then left the final touches to his son.

We stare up and I ask myself, Would I ever devote my life to anything?

No directions, …… I always used to hear those words in my father's voice. Now I hear them in my own.

    The next day we're at Yellowstone National Park, where we have a picnic.

"Did you ever travel with your dad? I ask.

"Only once," he says. " I never spoke much with my father. We loved each other—but never said it. Whatever he could give me, he gave.">

    The kast sebtebce—it's probably the same thing I's say about my father. And what I'd want my child to say about me.

In Glacier National Park, my father says, "I've never seen water so blue." I have, in several places of the world, I can keep traveling, I realize—— and maybe a regular job won't be as dull as I feared.

    Weeks after our trip, I call my father.

"The photos from the trip are wonderful," he says." We have got to take another trip like that sometime.

    I tell him I've learn decided to settle down, and I'm wearing a watch.

    Earlier this month, blogger Lisa Henderson announced that she and her husband John had decided not to have Christmas. The family, who lives in Utah, will still put up decorations, but presents from Santa are a no-go this year.

    “John and I feel like we are fighting a very hard uphill battle with our kids when it comes to their rights,” Henderson wrote on her blog. “It is one of the biggest struggles as a parent these days in middle class America. Our kids have been acting so ungrateful lately. ... John said, “We shouldn't just celebrate Christmas. And, so that's what we did.”

    Instead, the Hendersons are putting the money they would have spent on gifts toward service projects in order to teach their three sons the “pleasure of giving.” The children will still receive gifts from grandparents and other family members, but this year, she said, their letters to Santa will be asking him to find someone who needs presents more than they do.

    In an interview with ABC News, 11-year-old Caleb Henderson admitted that he and his brothers had been behaving badly. “We would hit each other. We were fighting and crying,” he admitted, and Lisa said that when she broke the news to her sons, they cried pretty hard.

    But so far, Henderson told Fox News last week, the family is having a sudden turning this into a different kind of gift. They have already held a clothing drive and sent boxes of clothes and candy to a village in the Philippines that was hit hard last year by Typhoon Haiyan.

    “The children were excited and kept wanting to give more and more,” she reported on her blog.

    Many readers responded positively to Henderson's post. Some sharing their own stories of limiting Christmas in order to teach their children to be charitable(仁慈的) or grateful. “As parents you're giving your kids something so much more special than a bunch of gifts on Christmas,” one wrote.

    But Henderson received negative follow-ups as well on her blog. Responding to critics, she updated her blog with a statement that reads, in part:

I just wanted to explain a couple of things. First, my kids are in no way hurt for things.... They have reacted by making gifts for each other and packing them into each other's stockings stealthily(偷偷地). They are learning exactly what we wanted them to learn, because they are not moving around feeling sorry for themselves. They are thinking of others.

    The second thing I wanted to explain is why I wrote this post. Some people seem to think I wrote this for attention. Ummm, the attention you get from posts like this is not good and actually extremely difficult to deal with.... The reason I wrote this post is I want to empower parents to feel like it's okay to take a stand. ... I wanted to share what we are doing, so any parents that feel they are struggling with the same issues in their home can see what others are doing and get ideas for their family. My intention is to help support other parents and to raise amazing kids.

    Many people turn to doctors or self-help books, but they ignore a powerful thing that could help them fight illness: their friends.

    Researchers are only now starting to pay attention to the importance of friendship in health. A 10-year Australian study found that old people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk  for obesity (肥胖) among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could improve brain health as we age.

    “In general, the role of friendship in our lives isn't well realized,” said Rebecca, a professor at the University of North Carolina. “Friendship has a bigger effect on our psychological health than family relationships.”

    While many friendship studies are about the close relationships of women, some research shows that men can benefit, too. In a six-year study of 736 middle-aged men, having friendships reduces the risk of heart attack. Only smoking was as important a risk factor (因素) as having little social support.

    Exactly why friendship has such a big effect isn't entirely clear. While friends can send a sick person to the hospital or pick up medicine, the benefits go well beyond physical assistance. Friendship clearly has a big psychological effect. “People with stronger friendships feel like there is someone they can turn to,” said Karen, a doctor. "The message of these studies is that friends make your life better.”

    Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

    On Thursday night my two adult children took us out to dinner as our daughter lives in Bathurst and she will be there for Father's Day with her husband's side of the family. Two of our grandchildren were able to join us.

    Having pre-celebrated my Father's Day and it being on our minds, my wife asked this question only this morning:

    "Do you remember anything about your father?"

    While this subject had come up before, however, the question had not been put so bluntly(直率的). I answered "No. My only memory is of the few photos outside." You see, my father died when I was only four years old.

    Many people have lost their father early in life and it is easy to feel somewhat sorry for having to deal with such a situation, especially when the death has occurred when you are at an early age. On reflection, I think I do not remember anything because he passed away when he was a member of the Royal Australian Air Force. He was a Corporal(下士) doing land based duties, however, a medical condition took his life. It was 1942.

    The 2nd World War was in full battle and Australia was being attacked. My Mum and I with my younger brother, were living with my grandparents and I can only imagine the emotional circumstances that existed in the household at that time. Probably not something that would leave a memory.

    What I would like to say at this time, as the question is often asked, "What did you learn from your father?" The thing I learnt from his passing, at the age of 28, is a love of life. What I do remember is growing up wondering if I would live to his age, and after I did, thinking each year the bonus(津贴) of life I had been blessed with when compared to my father.

    I have sometimes felt disappointment in not knowing my father but life has moved on. However, can I say to those who do have fathers, celebrate today with him and return him all the love and happiness he has given to you.

    Researchers at the University of York in England published their findings on facial recognition that, on average, people can remember as many as 5,000 faces.

    There have been many studies recently on facial recognition technology. But the authors of this study say theirs is the first time that scientists have been able to put a number to the abilities of humans to recognize faces. Rob Jenkins, leader of the research, said the researchers' study centered on "the number of faces people actually know." and were not able to discover whether there is a "limit on how many faces the brain can handle."

    Jenkins said the ability to tell individual people apart is "clearly important." In today's modern world of big cities, we meet and deal with thousands of people. The study suggests our facial recognition abilities help us to deal with the many different faces we see on the screens, as well as those we know. The results of the study give a baseline for comparing the "facial vocabulary" of humans with facial recognition software.

    Today, facial recognition technology is used in many ways, including by law enforcement agencies to prevent crime and violence. Governments use it to keep secret areas secure and, in extreme cases, control populations. Some governments use the software to watch people and find out where they go and what they do. Even Facebook uses facial recognition. For example, when you name a friend, Facebook technology may recognize the person's face from a different picture you had shared before.

    For the human study, people spent one hour writing down as many faces from their personal lives as possible. At first, they found it easy to come up with many faces. But by the end of the hour, they found it harder to think of new ones. Their change in speed let the researchers estimate when they would have run out of faces completely. 1,000 to 10,000 faces remembered. People who took part in the study were also shown thousands of photographs of famous people. Researchers asked them which ones they recognized. To make sure they knew these people, researchers required them to recognize two different photos of each famous person. The results showed that the participants knew between 1,000 and 10,000 faces.

    How do they explain such a wide range? Jenkins said one explanation may be that some people have a natural ability for remembering faces. "There are differences in how much attention people pay to faces and how well they process the information." Also it could be because of different social environments. Some people may have grown up in more populated places. So, they may have had more social contact throughout their lives.

    Researchers think age may be an interesting area for further research. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said. He said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.
