One evening, author Neil's son was angry. Neil had said one of those things that parents say, like “isn't it time you were in bed.” His son looked up at him, angry and said, “I wish I didn't have a dad! I wish I had … a goldfish!” That conversation gave birth to Neil's book, “The Day I Swapped My Dad for Two Goldfish”. The book is a funny adventure of a son searching for the dad he swapped.

    Whether they realize it or not, fathers play an important role in their children's development. Roland Warren, Director of the National Fatherhood Initiative, says that, “The shape of their dads has a role in the kids' soul.” I agree. We live in the best of times and the worst of times for fatherhood. We live in the best of times because fathers who are engaged in their child's life spend more time than fathers of any previous generation. We live in the worst of times because there are still millions of children who continue to miss the regular presence of Dad.

    What difference does a dad make? Are they really that important? For the most part, studies have proved clearly that fathers, whether they live with their children or not, matter in the lives of their children. When fathers are present, they provide economic support for their children and caregiving responsibilities. Well-fathered children are shown to be more emotionally intelligent and socially successful as adults. When fathers are absent, their absence may negatively influence children's academic achievement, general behavioural adjustment and anger management, especially in males.

    Yet just being physically present isn't enough to be a great father. It is important that a dad be warm and emotionally available to his child. Author and researcher, John Gottman, describes this kind of father as an “emotion coaching father”. Emotion coaches are parents who listen to their children's feelings, see the sharing of feelings as an opportunity for intimacy（亲密）. It is not just the mere presence of fathers that matters, but how they are present. Most children long for and need a loving, devoted and responsible father.

    Young people almost never get a good press(评论) these days. “Their outlook is centered on trashy books and films,” expressed one citizen in a letter I recently came across in the Daily Mail. It seems that people have been complaining about the young since ancient times. However, the young are probably no worse than they've ever been. And I think they're better. Teenagers today are brighter, more energetic, more outgoing, and more interesting than any generation before.

    The truth is, we hear plenty of bad news about youth, but we never hear about the majority. Surely they all want to be footballers or attractive models? Not a bit of it. When research company Britain-Thinks examined teenagers attitudes earlier this year, they found that the most popular goal (shared by some 70 percent) was to “have a job you love”, followed by having a university degree, owning your own home and being in a happy, long-term relationship. It tallies with another study by the Institute for Economic and Social Research, which found that what made teenagers happiest wasn't a new smart-phone or pair of shoes, but “the simple things in life” such as close friends, going swimming and spending time with their parents.

    Indeed, the more you look at the young, the more impressive they seem. They are, of course, more technologically knowledgeable and skillful than any generation before them. But the interesting thing is that they're not merely consumers; they're creators. Think of all those young people developing their own websites or machines.

    Seventeen-year-old Nick D'Aloisio is an example. He invented a news-summary app (应用程序)called Summly and sold it to Yahoo this year for a reported £18 million. The company offered him a job in California, but he turned it down. “I'll be staying in London,” he explained. “I want to finish my A levels and I couldn't really live on my own out there.”

    Of course they aren't perfect, and every generation has its fair share of bad apples. But I think our future is in safe hands.

    During the past Spring Festival, many children may have received red packets from their families. But Xing Pu, a 40-year-old economist, is asking the government to give red packets to every Chinese citizen.

    Xing suggested the government give out 1,000 yuan to each Chinese since the government income has increased rapidly in recent years. He said his suggestion would allow everyone to directly enjoy the fruits of the country's economic success, help the lower-income groups deal with rising prices and increase consumption around the country.

    Recent years have seen the government carry out a series of pro-poor (扶贫) and pro-rural (惠农) policies, including increasing spending on public health-care and cutting down the agricultural tax. But the lower-income group still needs more help.

    Xing said he has borrowed many ideas from practices in countries like the United States and Singapore. Earlier this year, the governments of the two nations offered cash handouts (救济) to their citizens. As for in China, 'We can even encourage the rich to donate their 1,000 yuan red packet to the poor,' said Xing.

    Although Xing's suggestion has gained wide support among ordinary Chinese on the Internet, many other economists criticized it as unpractical. 'To better use the increase of money, handing out money is not a solution that holds good for all time. It could be better to improve the public service or cut the price of energy use in daily life,' said Qiao Xinsheng, an economic professor.

    When many people are worried that there are no more heroes in modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist (存在).

    According to the Inner Mongolia Morning Post, the accident occurred on the afternoon of December 14, 2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water.

    More than 20 university students who happened to be near the spot immediately went to the rescue of the children.

    Two children were quickly rescued, but the third died. The child's body was not found for three hours. Two of the rescuers, Liu Ye and Hao Longbiao, also died of cold and exhaustion (筋疲力尽).

    The body of Hao who took the lead in jumping into the lake was not found until the next day.

    A student who was unwilling to tell his name said he and his classmates from the local college were taking photos at the lake. When they heard the children's cries for help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water.

    Local residents held mourning ceremonies (祭奠仪式) at the lake.

    Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation, but their lives were no longer in danger.

    I had a lot of teachers that I loved. However, the teacher that I remember most was Mrs Green from Marianna, Florida. She was my 5th grade teacher. Since I was a new student, not only in her class, but at the school, she made my time there much more pleasant. I immediately began to like her. She was really funny and I knew that she liked me. She made learning fun. I remember one day for Christmas holidays, she taught us how to make ornaments (装饰物) from eggs. My parents still have some of the ornaments I made.

    She made me leader for many group projects and that made me feel special. I think that would make any child feel special, especially when a child is in a new place with no friends. She made me want to be like that. Not to pick a "favourite" student, but to make every student feel that they are special. That year, I received the Presidential Academic Award (美国总统学术奖). I was really proud and so were my parents.

    Looking back at it, I think the reason why I did so well was that I felt important. Students do better when they feel like they are important or loved. Mrs Green always gets to know her students and forms personal relationships with them, which I will try to do some day. I just hope that there will be a student who finds me to their favourite teacher as I found her to be mine.

    Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part－drivers.

    DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.

    One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The "winner," if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.

    "You get a lot of respect for natural abilities of the living things," says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. "Even ants (蚂蚁) can do all these tasks effortlessly. It's very hard for us to put these abilities into our machines."

    The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately. Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there's a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
