Think back to a time in your life when you tried something new. When I was a teenager I volunteered to pass out water at a local race. I was so excited to see all the different runners who passed by and quickly took a cup of water. Some ran past，some walked past and a few wheeled past. I saw so many types of people doing it. I thought maybe I could do it too! The next year I decided to run for the race，but I had little running practice. I just wanted to finish. On the day of the race，it was terribly hot. After running for about 5 miles，I was thinking，“I must be crazy. Why did I do this? What was I thinking？” And at one moment，I said to myself，“I am never doing this again！” That first 10 km race was quite an experience. I jogged (慢跑)，I walked，I jogged and walked. At times，I didn’t know if I could finish. Near the end，a 70­year­old man ran past me，very fast，and I felt a little embarrassed (尴尬的) that I was more than 50 years younger than he and I couldn’t even keep up with him. But then I realized something. He was running his race and I was running mine. How often in life do we compare(比较) ourselves to others when we really shouldn’t? I decided that I would not give up on running races，and that one day I would be one of those 70­year­olds who were still running. As I crossed the finishing line，I was proud of myself. I didn’t regret (后悔) having such an experience. 小题1:What did the writer do at a local race as a volunteer? A．He helped old runners. B．He cheered up the runners. C．He passed out water to the runners.
