　　托福阅读修辞目的题：mystery of yawning

　　【Paragraph 4】The empirical evidence, such as it is, suggests an altogether different function for yawning—　namely, that yawning prepares us for a change in activity level. Support for this theory came from a study of yawning　behavior in everyday life. Volunteers wore wrist-mounted devices that automatically recorded their physical activity for up　to two weeks: the volunteers also recorded their yawns by pressing a button on the device each time they yawned. The　data showed that yawning tended to occur about 15 minutes before a period of increased behavioral activity. Yawning　bore no relationship to sleep patterns, however. This accords with anecdotal evidence that people often yawn in　situations where they are neither tired nor bored, but are preparing for impending mental and physical activity. Such　yawning is often referred to as "incongruous" because it seems out of place, at least on the tiredness view: soldiers　yawning before combat, musicians yawning before performing, and athletes yawning before competing. Their yawning　seems to have nothing to do with sleepiness or boredom—quite the reverse—but it does precede a change in activity　level.(The mystery of yawning)

　　! Why does the author mention “soldiers yawning before combat, musicians yawning before performing, and athletes　yawning before competing”?

　　○ To argue that just the expectation of physical activity can make some people feel tired

　　○ To explain how the view that people yawn because they are tired accounts for yawning before stressful situations

　　○ To support the view that yawning helps prepare a person for mental or physical exertion

　　○ To provide anecdotal evidence that conflicts with the experience of the volunteers in the study
