Baloo the bear, Leo the Lion and Shere Khan the tiger have the most unusual and unlikely friendship between them. They were saved eight years ago, when they were cubs only two months old.

    They were first sent to a rescue（救护）center, where they were raised together. Now they are in an American zoo. Because they came here as a kind of family, the zoo built a large clubhouse so that they could all sleep in it.

    Now they have grown up. You can see them playing around like brothers. The three big animals seem to no sense(意识) of their animal differences.

    Baloo and Shere Khan are very close. That is because they rise early, as Leo being a lion likes to spend most the day sleeping. When Leo wakes up the three of them mess around for most of the day before they settle down to some food. It is wonderful to see a giant American Black Bear put his arm around a Bengal tiger and then to see the tiger touch the bear with his nose lightly like a pet cat. You can often see they lie on top of each other for heat and for love.

    “They are not wild animals any more. But you must remember who you are dealing with when you are with them,” said one of the zoo keepers.

    I have two good friends. They are Gina and Jenny, and they are twin (双胞胎之一的) sisters. They come from Singapore. They are 12 years old. They can speak English and Chinese.

    Now the twins are in China. Their family are in China, too. They live in Shanghai. There are five people in their family. They are their parents, their brother and them. Their mother is a doctor. Their father is a teacher. Their brother Alan is very young. He is four years old. He can't go to school.

    Gina, Jenny and I are in the same class. Every day, we walk to school and talk a lot. They say China is a very good place and they like China.

    As the saying goes, “Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime.” This is the way the charity organization Heifer International (国际小母牛慈善组织) wants to end world hunger.

    It began in the 1930s when an American farmer, Dan West, went to Spain to help people in need. He tried to feed the people with milk. But it seemed that there would never be enough milk. It made him think that what they needed was “not a cup, but a cow”.

    Dan West returned to America. He worked together with some friends to find ways to end hunger. He believed giving animals and providing training would stop world hunger. With his help, Heifer International was set up.

    On Heifer International's website, you will see a list of animals like cows, chickens, pigs and even fish and bees. You can offer help by buying some animals for one certain family. Those animals will have babies get better lives, they will pass on the act of kindness to others. More importantly, you are buying the resources (资源) for programs run by Heifer International to help more families.

    The programs also help small-sized farms. As a rule, each farmer must give his animal's first female (雌性) baby to another in need. Heifer International also provides training on animals' health and feeding. And these farmers all agree to teach others what they have learned as another rule.

    However, there is still a long way to go. The milk may run out. But if families have their own cows, they can get plenty of milk to feed themselves. The organization wants the farmers to go on working together, helping each other and learning from each other. Maybe hunger can really be stopped.

    My father is seventy-five years old this year. But he looks very young. He looks like a sixty-year-old man. Now he can do everything all by himself. For example, he cooks, washes clothes, does the housework and so on.

    Every morning, my father goes out with a radio. He listens to the music or the news and goes to the park to play taijiquan. In the park, he talks and laughs with other old people. After coming back from the park, he begins to have breakfast and then he goes to the university (大学) for the old. He learns to draw there. In the afternoon, he plays on the computer for about one or two hours. After supper he watches TV and learns about the world. He goes to bed at about eight o'clock. He never stays up. He likes to share his ways of keeping healthy with others.

    Are you healthy? If not, what do you learn from my father's secret of keeping healthy?
