我想請大家一個跟題目無關的句子因為我看得很困惑 According to conventional theory, yawning takes place when people are bored or sleepy and serves the function of increasing alertness by reversing, through deeper breathing, the drop in blood oxygen levels that are caused by the shallow breathing that accompanies lack of sleep or boredom. Unfortunately, the few scientific investigations of yawning have failed to find any connection between how often someone yawns and how much sleep they have had or how tired they are. About the closest any research has come to supporting the tiredness theory is to confirm just a developmental fossil with no that adults yawn more often on weekdays than at weekends, and that school children yawn more frequently in their first year at primary school than they od in kindergarten 請問後面這句 About the closest any research has come to supporting the tiredness theory is to confirm just a developmental fossil with no that adults yawn more often on weekdays than at weekends, and that school children yawn more frequently in their first year at primary school than they od in kindergarten 用了no that 是再說沒有觀察到後面敘述的現象嗎但是前面的句子又說這個research 可以支持triedness theory 感覺是我理解出錯了可以麻煩大家幫我解答一下嗎謝謝 -- ※ 發信站 :批踢踢實業坊(ptt.cc) ◆ From: 114.39.59.125
