阅读与回答问题。（本大题共5小题，每小题2分，满分10分）
Jeff Keith has only one leg. When he was 12 years old, Jeff had cancer. Doctors had to cut off most of his right leg. Every day Jeff puts on an artificial(man-made) leg. The leg was plastic. With the plastic leg, Jeff can ski, ride a bicycle, swim and play soccer. He can also run.
When he was 22 years old, Jeff Keith ran across the United States, from the East to the West. He started running in Boston on April 1. He stopped running in Los Angeles. He ran 5,190 kilometres; that’s about 26 kilometres each day. Jeff wore out 36 pairs of running shoes and five plastic legs.
Jeff stopped in cities on the way to Los Angeles. In every city people gave Jeff money. The money was not for Jeff. It was for the American Cancer Society. The American Cancer Society used the money to learn about cancer.
On the way to Los Angeles, Jeff talked to people about cancer. He also talked about being disabled. Jeff is disabled, but he can do many things: he skis, swims, plays soccer, and runs. He finished college and is studying to be a lawyer. Jeff says, “People can do anything they want to do. I want people to know that. I ran not only for disabled people. I ran for everybody.”
