Living things can regulate their own activities in such a way that they fit into the rhythms (节奏) in nature. For example, plants consume (大量吸收) sunshine during the day and do most of their breathing at night. Small animals which live in very hot regions remain deep in their holes during the heat of the day and only come out at night to obtain food. These rhythmic patterns of activity in living things can be called biological clocks.
Scientists have discovered some very interesting facts about biological clocks. Their most important discovery is that although biological clocks approximately (近似地) correspond to the rhythms of day and night, light and darkness, they do not always depend on them. Many biological clocks are independent. How can this be proved? It can be proved by showing that a biological clock will continue to operate even when its surroundings are changed so that it can no longer respond to alternating periods of lights and darkness.
We will take the crab (蟹) as an example. This animal is a living clock. It indicates (指出) the time by the color of its skin, which is dark during the day and lighter in color during the night. The daytime darkness of the crab's skin, which prevents its enemies from noticing it and also prevents the crab from getting too hot, is repeated every 24 hours. The alternating colors of the skin appear to follow the alternating rhythm of day and night. How can we prove the statement that crab is an independent clock which creates its own rhythm, its own time? Perhaps it only responds to sunlight, by growing darker when in contact with sunshine and growing lighter in color when the sun sinks behind the horizon (地平线)?
To answer this question, biologists did a simple experiment. They kept the crab in a dark room at a constant temperature for two months. They found that the skin of the crab continued to change color according to the same 24-hour rhythm, following the movements of the sun outside. In this way they proved that the crab's biological clock was independent of events in its natural surroundings. It was not just a series of responses to external events.

Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body.
Our bodies use varying（不同程度的） amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food.
| A. Meats Slice of bacon 50 Hamburger 300 Slice of beef 100 Sausage 180 Meat pie 500 Sausage roll 350 |
