The following text is for questions 11 to 13.

Last year I joined the Chicago marathon. My
first marathon contest. I had to run 26.2 miles to
complete it. It was hard.
At first, I just wanted to get the experience of
joining a marathon. I thought it would be one life
time experience. After finishing it, I changed my
mind. I wanted to join another one. I was
interested to complete at least one more marathon
and improve my time. I also experienced a good
feeling between participants and the spectators
that made me happy. It was a very wonderful
thing for me. So I decided that I had to join
another marathon the following year.
