When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, "Homeless to Harvard: The Liz Murray Story" shown in late April.

    Liz Murray, a 22.year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just l5 years old. The effect of that LOSS became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died,she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. ".What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being. I had only experienced a small part of the society,'' she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that "next to nothing could hold me down".

    She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS."I love my parents so much. They are drug addicts. But I never forget that they love me all the time."

    Liz wants moviegoers to come away with the idea that changing your life is "as simple as making a decision".

    The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

    Nowadays there is less and less contact between the old and the young. There are many reasons for this, but the result is the same: increasing numbers of children without grandparents and old people who have no contact with children. And more old people who are lonely and feel use- less, along with more and more families with young children who desperately need more support. It's a major problem in many societies.

    That's why intergenerational programmes, designed to bring the old and the young together, are growing in popularity all over the world, supported by UNESCO and other local and international organisations. There are examples of successful initiatives all over the world. Using young people to teach IT skills to older people is one obvious example. Using old people as volunteer assistants in schools is another, perhaps reading with children who need extra attention.

    One successful scheme in France is combining a residential home for the elderly with a creche/nursery school in the same building. The children and the residents eat lunch together and share activities such as music, painting, gardening and caring for the pets which the residents are encouraged to keep. In the afternoons, the residents enjoy reading or telling stones to the children and, if a child is feeling sad or tired, there is always a kind lap to sit on and a cuddle (依偎). There are trips out and birthday parties too.

    The advantages are enormous for everyone concerned. The children are happy because they get a lot more individual attention and respond well because someone has lime, for them. They also learn that old people are not different or frightening in any way. And of course, they see illness and death and learn to accept them. The residents are happy because they feel useful and needed. They are more active and more interested in life when the children are around and they take more interest in their appearance too. And the staff are happy because they see an improvement in the physical and psychological health of the residents and have an army of assistants to help with the children.

    I must have looked deep in thought, or as deep in thought as an 11-year-old man can, when my grandmother glanced up from her weeding to ask, "You have something on your mind, don't you?"

    "Yes, I was thinking that someday I want to be an Olympic speedskating champion like my hero, Eric Heiden, I want to be a doctor like my parents and I want to help children in Africa."

    I immediately knew I had confided in the right person when a knowing smile broke across her face. "Johann, of course! You can do anything you want to do!" she said simply. And with my grandmother's support, I set out to pursue my passions.

    14 years later, I was well ready to take hold of my first dream: becoming an Olympic champion. The Olympics in 1994 were in my home country, Norway. As I entered the Olympic stadium, I wasn't the best athlete, and many had doubts about my ability to perform well. But I had something special working for me. I had a woman in the first row who believed in me following my passions just as much as I did. For the first time ever, my grandmother was going to see me skate.

    It happened. Breaking a world record, I won the gold.

    As I stood on the podium(领奖台) that I had dreamed about my entire life, a curious question popped into my head. Why me? Why did I win, given all the other incredible competitors out there? The reason had to be more than a grandmother who shared a belief in her grandson's dream. The question led me to only one answer: because I wanted to make a difference in the world, and with all the media attention on my success, I could.

    I immediately knew what that difference had to be: hope in the lives of the children in Africa. Six months earlier, I'd been invited to Egypt as an ambassador for Olympic Aid.

The Gift of Life

    Most couples demonstrate their love on February 14 with flowers or chocolates. But these four men and women have offered the ultimate loving gesture—the gift of life. Each sacrifice has enabled their loved ones to live full and active lives again after serious illness.

    I'D Do THE SAME FORHER

    Michele Johnson, 53, has been married to Gay, 57, for 26 years.

    With her husband suffering from a congenital(先天性的)kidney condition, in 2013 Michele  gave him one of him. Gay said: “I needed to be hooked up to a dialysis(透析)machine. I had no quality of life at all. However, I felt great as soon as I woke up after the operation. I told her I'd do the same for her.”

    I LOVE BRENDA TO BITS

    Brenda Green, 62, met her husband Keith, 63, when she was 24 and they married five years later. When Brenda was told five years ago she needed a kidney transplant, she cried. I Ⅱ give you mine.” Keith said without hesitation. “Brenda is my wife and I love her to bits.”

    MY WIFE'S MY HERO

    Stephen Heavyside, 61, and wife Patricia, 62, have been married for 40 years. Stephen said: “I was diagnosed with adult polycystic kidney disease five years ago. Patricia took good care of me and donated a kidney. This has brought us even closer.”

    He said “Patricia's gift changed my life. She is my hero.”

    DECISION WAS EASY

    Anna Stevens, 48, and husband Gary, 53, of Watford, Herts, have been wed for 23 years. Anna donated a kidney to her husband. She said of the transplant: “It was the easiest decision I've ever made.” Gary said. “There's only two words that I can use to describe her:  My angel.”

    Many of us love July because it's the month when nature's berries and stone fruits are in abundance. These colorful and sweet jewels form British Columbia's fields are little powerhouses of nutritional protection.

    Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious. Who cares? However, they are rich in vitamin C.

    When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat "ice cream". For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

    If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a "soft-serve" creamy dessert, to be eaten right away. This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
