Have you eaten too much over the holidays You should try fidgeting for a while. Those around you might not like it, but scratching (moving your nails (指甲) against a part of your body) and twitching (moving suddenly and quickly when you don’ t want to) is an important way of burning up calories (卡路里). American researchers have found that some people’s squirming ( continuously turn your body when nervous) and wigging (move in small movements, especially from side to side) equals (等于) several miles of slow running each day. The scientists, based at the National Institute of Heahh’s laboratory in Phenix, Arizona, are studying why some people get fat and other stay slim. In one study 177 people each spent 24 hours in a room in the institute where the amount (量) of energy is measured by their oxygen and carbon dioxide (二氧化碳) levels. By the end of the day, some people had burned up 800 calories in toe-tapping, (moving the front part of your foot up and down) finger-drumming (hitting your fingers continuously and lightly against something hard) and other nervous habits. However, others had burned up only 100 calories. The researchers found that slim women fidget more than fat women, but there was no significant difference in men. Heavy people burn up more energy when they fidget than thin people do. Which of the following can be used to explain the meaning of "fidgeting"

A. Scratching and twitching.
B. Squirming and wigging.
C. Slow running.
D. Moving one’s body nervously.
