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. 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 chart below shows. Also, the number of calories you use at any 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 mainly in the form of three kinds of chemical materials—carbohydrate（糖类）,protein and fat. Carbohydrate provides 3.8 Cal/gm（calories per gram） of energy, protein 4.0 Cal/gm and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the second chart shows.
Chart Ⅰ
| CALORIES NEEDED PER DAY | |
| BABY | 750 |
| OFFICE WORKER | 2 700 |
| CHILD AGED 8 | 2 100 |
| WOMAN FEEDING BABY | 2 700 |
| MAN OVER 70 | 2 100 |
| BOY AGED 16 | 3 000 |
| WOMAN | 3 600 |

| MILK | 30% | 30% | 40% |
| RICE | 5% | 10% | 85% |
| PEANUTS | 60% | 30% | 10% |

C. a mother with a baby to feed uses up more calories than a hard-working farmer each day
D. an old man needs less calories than an 8-year-old boy on account of his less movement
4.Which of the following statements agrees with the passage and the charts above?
A. You need more calories for swimming that for mountain climbing.
B. If you take an equal amount of Vitamin containing the calories you need, you don’t need to eat any food at all.
C. Different people need different amounts of energy depending on their age, sex and the activities they are in.
D.3 grams of milk provides 16.6 calories because carbohydrate provides 3.8 Cal/gm, protein 4.0 Cal/gm, and fat 8.8 Cal/gm.
