If you are a sleep deprived teacher, you may not be aware of the term woodpeckering ，but you’ve probably done it. It happens the day following a bad night’s sleep. You’re sitting in a long meeting and you can barely keep your eyes open so you support your head up with your hand. Next thing you know, you are moving your sleeping head back to its uptight position. Do this a few times and you are woodpockering.
I thought I knew sleep deprivation when I did my medical internship in hospital. That year I frequently went 36 hours with no sleep. When I finished my stay in neurology，I welcomed the promise of full nights of sleep ever after. It went pretty well for the next 10 years, until I became a school teacher and experienced a whole new level of sleep deprivation.
Teachers’ working hours go far beyond the 8 am to 5 pm schedule of kids in school. There are hours spent at staff meetings, correcting homework, preparing for the next day— and then there is the worrying. What I did in a hospital emergency room required no more intensive mental energy than what is needed to keep 30 kids attentive enough to learn what I was teaching.
Good teachers are like magicians keeping a dozen balls in the air to come at right time, with alarm set for 6 am to finish grading papers, memories of the day that’s gone — including the students who didn’t understand something, forgot their lunch or were embarrassed by wrong answers. All these will become sleep resistant barriers. And also with some financial stress, you’ll have a cycle of insomnia with unwelcome consequences.
With inadequate sleep comes irritability，forgetfulness, lower tolerance of even minor annoyances, and less efficient organization and planning. There are the very mental muscles that teachers need to meet the challenges of the next day. In wanting to do a better job the next day, the brain keeps bringing up the worries that deny the rest in needs.

【答案】D，细节题。根据原文第一段原文“you may not be aware of the term woodpeckering (啄木鸟式点头)，but you’ve probably done it. It happens the day following a bad night’s sleep.”得出，你可能不清楚啄木鸟式点头，但你已经这样做了，因为前一天晚没睡好。
【答案】B，细节题。根据第二段“until I became a school teacher and experienced a whole new level of sleep deprivation.”得出，我成为一名学校老师的时候经历了一个全新的睡眠剥夺程度。
【答案】D，推断题。根据第三段“What I did in a hospital emergency room required no more intensive mental energy than what is needed to keep 30 kids attentive enough to learn what I was teaching.”得出，我在医院紧急室里没有在学校经历的精神能量强度更大。
【答案】C，推断题。根据第四段“Good teachers are like magicians keeping a dozen balls in the air to come at right time, with alarm set for 6 am to finish grading papers, memories of the day that’s gone”及“All these will become sleep resistant barriers.”推断出，老师在一天的工作时间内在不断处理种种事务，对教学工作很努力投入。
【答案】B，推断题。根据最后一段“With inadequate sleep comes irritability(易怒)，forgetfulness, lower tolerance….”“There are the very mental muscles that teachers need to meet the challenges of the next day.”推断，教师没有充足的睡眠，会产生许多问题，没有足够的精神肌肉来满足第二天的需要，因此推出，需要提前睡好。
