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.

| A．55. | B．175. | C．325. | D．275. |

The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.
◆Try to use new informati6n immediately. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say"____"
◆Break a big number into smaller parts. For example, it's hard to memorize (记忆) 109244153. But if you break it into three parts--109/244/153—it becomes easier.
◆Write out what you need to remember ever and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.
◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that clay.

It was a cold winter afternoon before Christmas. My parents and I sat on the bench in Washington, D.C.’s Union Station, waiting for the train. Inside the waiting hall were many people.
A boy sat nearby. His worn jacket, pale face, dirty hands all seemed to tell me that he was homeless.” He must be cold and hungry. Maybe I should help him,” I said to myself. Just at that moment, a well-dressed young couple walked towards him.” Excuse me,” the man bent down. “My wife and I bought two meal boxes but one was enough for us. We hate to waste good food. Can you help us out and put this to use?” he handed the boy a meal box. The boy thanked them and opened the box with joy and care. Suddenly he stopped.
In the direction to which he looked, I saw an old man in rags-in a worn sweater, worntrousers and open shoes, coming into the hall. Putting the meal box aside, the boy stood andhelped the old to his seat. He took off his jacket and covered it on the old man’s shoulders,
saying, “A gentleman brought me this warm meal but I just finished eating. I hate to waste good food. Can you help me out?” He placed the still-warm meal box in the old man’s hands without waiting for an answer.” Sure, son, but if only you share that sandwich with me. It’s too much for a man at my age. ”
We were all touched. Dad went away and soon returned with cups of hot chocolate and a big pizza. Mum and dad went up to those rags, “Excuse me…”
