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)

As a volunteer(自愿者) teacher, I traveled a long way to a small village school in Longzhou, Guangxi. On my way there, I thought about the village, the school and the childrenn there. However, my heart sank when I arrived there. It wasn't what I expected. It didn't look like a school at all! The school had only three rooms, one for Grades 1, 2 and 3, and the other for Grades 4, 5 and 6. There was a third one for me.

  The children welcomed me warmly on my first day. They asked me a lot of questions, and I told them stories about myself and my life in Shanghai. The next day, I gave them a test to find out their level(水平). To my surprise, though the test was very easy, over half of the students failed it, yet they all wanted to learn new things. I knew they needed me.

I was busy preparing lessons and reading test papers every night. I enjoyed teaching these lovely and hard-working children, and I could see that they were making progress(进步) with my help. I have also learned a lot from them. I understand their level is becoming higher and higher, and we are good friends now.

I worked in Longzhou for a year. I'm very happy, and the experience(经历) is very useful to me. I love the small village and the children. In fact, I would like to continue working here.
