Barrington Irving made his historic flight and founded an educational non-profit-making organization.The secret,he believes,is having a dream in the first place,and that starts with learning experiences that inspire kids to build careers.
The moment of inspiration for Irving came in his parents' bookstore.One customer,a professional pilot,asked Irving if he'd thought about becoming a pilot."I told him I didn't think I was smart enough;but the next day he took me to the cockpit(驾驶舱)of the commercial airplane he flew,and just like that I was hooked."
To follow his dream,Irving turned down a football scholarship to the University of Florida.He washed airplanes to earn money and increased his flying skills by practising at home on a $40 flight simulator(模拟) video game.Then another dream took hold:flying alone around the world.He faced more than 50 rejections for sponsorship before convincing some companies to donate aircraft components.He took off with no weather radar,no de-icing system(除冰系统),and just $30 in his pocket.
After 97 days,26 stops and dozens of thunderstorms,he touched down to a cheering crowd in Miami."It was seeing so many young people watching and listening that pushed me into giving back with my knowledge and experience." Irving has been doing it ever since.He set up his non-profit-making organization,Experience Aviation(航空),aiming to increase the numbers of youth in aviation and science-related careers."We want to create chances for students to accomplish something amazing,"he notes.The most powerful educational tool is the example his own life provides.
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. |
