During an doctors found bone cancer in my left leg. (be / cut / needed / off / the leg/to). But I wasn't giving up; I wanted to do sports again. Desc Sports were always my passion, and, like many children, I wanted to be a 5 professional football player. But I realized this would not be possible and started training for track and field events. My new *prosthesis, an artificial leg, was a new beginning for me. テーマ スポーツ (100) I am often asked why I chose to be a *sprinter. The point is, I run because I'm missing a leg. In other words, although I lost my leg, I learned something very 10 important: Accept your challenge and try to ( 3 ) it. Everything can be an opportunity if you only realize that it is. Note I started my sports career in 2001. In 2004, I participated in the Paralympics in *Athens for the first time and won three *bronze medals in the 100 meter, 200 meter, and *long jump. At the 2012 Paralympics in London, I won gold in the 100 meter 15 sprint. G 25 prinodail It sounds so easy now, but it wasn't always like that. My own experience makes me focus on helping others, especially children. I spend a lot of time visiting children in the hospital who are in a similar situation.

When I pull up my *pant leg and show the children my prosthesis, you can see their eyes get big. But then they soon come to understand that everything is possible, even with a *disability.

Is our society a nice place to live in? Probably most ( ) you say, "Yes," but some people may say, "No." Actually, these people are sometimes (2) trouble. ( 3 ) example, some people in wheelchairs can't push the buttons of a public phone in a high place easily. They may also have trouble when they want to go up the stairs. Some people are trying to improve these kinds of problems. Some public buildings have 5 slopes or elevators for those people. That's not all. Some people have problems ( 4 ) their legs. There are special types of cars for them. Some people can't see well. There are special types of computers for them. Some people can't hear well. In some cities, there are fax machines ( 5 ) public phones for them. We will have more good ideas in the future, but I think there is another important 10 thing. Last year a group of Japanese people in wheelchairs made a trip to Italy. To move around in Italy was not always convenient for them, but they had a very good time. Why could they enjoy the trip? The answer is the warm heart of the people there. Many people ( the group / took / came / care / them / to / and / of ) by pushing the wheelchairs. I hope everybody in Japan will be like them in the future.
