It had been a long winter. Bitter cold, snowy days had hit us again and again. On the warmer days there had been little sunshine, but only cold, icy rain. The sun had become such a rare sight that I had to look at a picture of it on my wall calendar from time to time to remember what it looked like. The grass had remained brown and dormant(潜伏的)in the grassland. My own backyard had turned into a muddy mess that tried to steal the shoes right off my feet as I walked on it. My heart ached and longed for spring, and my own good cheer had trouble rising up against the continuous, cold, gray days.
The rain poured down on me as I walked my dogs, holding their leashes in my icy fingers. I looked up at the sky hoping to see the sun smiling down with its warm, golden face. But it was no use. It was then, however, that I saw it. It wasn't the smiling face of the sun in the sky but a little, yellow face peeking(微露出) through the mud. It was a tiny flower, and it filled my heart with hope and joy. I smiled and thanked God for this little sign that winter would soon be over and that spring would arrive. I felt my good cheer rising up at last and I promised God that I would share it with everyone I could.
One day that tiny flower's seeds will fill the grassland with little, yellow faces smiling up from the ground. Its work will make this world a better and more beautiful place. May we all do the same. May we all shine our light and share our love even on the coldest and grayest days. May we all help to share a bit of spring in winter. May we all work to make this world better and brighter even when it is at its darkest.
Animal training refers to teaching animals specific responses to specific conditions or stimuli (刺激). Training may be for the purpose of companionship, detection, protection, entertainment or all of the above. | |
An animal trainer may use various forms of reinforcement (强化) or punishment to condition an animal's responses. There are many ways to train animals and as a general rule no legal requirements or certifications (证书) are required. | |
Chickens Training chickens has become a way for trainers of other animals (primarily dogs) to perfect their training technique. Bob Bailey, former director of Animal Behavior Enterprises and the IQ Zoo, teaches in chicken training courses where trainers teach chickens to tell different shapes, to navigate an obstacle course and to chain behaviors together. | |
Fish Fish can also be trained. For example, a goldfish may swim toward its owner and follow him as he walks through the room, but will not follow anyone else. The fish may swim up and down, signaling the owner to turn on its aquarium (鱼缸) light when it is off, and it will skim the surface until its owner feeds it. Pet goldfish have also been taught to perform more complicated tasks, such as doing the limbo (a kind of dance) and pushing a miniature soccer ball into a net. | |
Pigs Among all animals, they are the third cleverest — monkeys, dolphins and pigs. Scientists think the training of pigs is easier than the training of dogs and cats. Pigs have a very good sense of smell. They can find things nearby or faraway. They can also help the police to find out drugs at an airport or at a train station. |
