     Tom Whittaker, born in England in 1949, is an amazing example of a Can Do person. The

young man came to the United States in 1975, where he studied for a Master's in Arts. Although

studying took up much of his time, he traveled throughout the US and Canada climbing many

different types of rock walls. Thus, he made friends with many people with the same interest.

     However, on Thanksgiving Day in 1979, a car driven by a drunk driver lost control and

suddenly turned into his lane(车道), striking the head of his vehicle. The injuries to both of his

legs and feet resulted in the removal of one of his kneecaps(膝盖骨), and the amputation(截去

)of his right foot.

     It wasn't easy, but after some time, with great effort and strong will, Tom rebuilt his hope

for life. The report of his story moved the whole nation of America. Eventually he earned another

master's degree and founded the Cooperative Wilderness Handicapped Outdoor Group. This

program's success sent Tom around the world to spread his message that "it is not the falling

down, but the getting back up that matters". He became a professor in Adventure Education

at Prescott College in Arizona, where he taught the top outdoor leadership program in the nation.

     After 25 years of experience as a mountaineer, on May 27, 1998, Tom achieved his greatest

accomplishment so far:reaching the peak of Mt. Everest. Tom was actually the first person with

a disability to ever climb and stand on the peak of Mt. Everest. He realized that reaching the peak

of Mt. Everest could do nothing to change his disability, but it could do a lot to change attitudes.
