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. With more and more animals, these families will be able to support themselves. Once these families 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 (雌性的) 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.
The human spine（脊柱） doesn't just help us stand up straight. Inside the spine is the spinal cord (脊髓) {#blank#}1{#/blank#} The legs and feet send "sense" information to the brain, saying they're hurt or hot, for example. And the brain sends messages to the lower body, telling the legs to walk, dance or sit down.
When someone's spinal cord is hurt, information about senses doesn't reach the brain from the lower body. And control messages can't make it to the lower body from the brain. {#blank#}2{#/blank#}
Surprisingly, now scientists in Switzerland have given three paralyzed men the ability to walk again. All of the three men had damaged their spinal cords in motorcycle accidents and couldn't move their legs. To help them walk again, a special device (装置) was put directly on the lower part of their spinal cord.
The scientists controlled the device from a computer. {#blank#}3{#/blank#} In the past, scientists have had some successes with the similar device in the lower spine. Some patients have even trained themselves over months to be able to walk.
But this research is different. {#blank#}4{#/blank#}Instead, the computer tells the device to send "walking" messages. The scientists use computers to create patterns of movement—like taking a step—that work well with each patient. The patients then choose the pattern they want, and the muscles (肌肉) move in the chosen way.
Over time, the three men are able to walk on their own, using a special walker with buttons to trigger (激发) each leg. {#blank#}5{#/blank#} The scientists are hopeful that in the future, this technology will allow more paralyzed people to walk again.
A. When that happens, a person is paralyzed (瘫痪的). B. The patients' brains aren't sending "walking" messages to their legs. C. The solution isn't perfect and the patients can't walk without the system. D. One of them has walked for half a kilometer on his own with the walker. E. It carries important information between the head and the lower part of the body. F. Just hours after the device was first used, all the three men were taking steps, with support. |
