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.

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate(碳水化合物), protein(蛋白质) and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein C= carbohydrate F=fat)
