word="pick">pick</span>-<span word="me">me</span>-<span word="up">up</span>指提神饮料，也就是一种剌激物，在这篇文章里具体指咖啡。所以，答案应选 <span word="C">C</span>。 3. <span word="A">A</span>第三段涉及的是一个实验，这个实验的目的是测试含咖啡因咖啡和脱咖啡因咖啡对睡眠的影响，该段主要谈论的是这个实验的结果。 5. <span word="B">B</span> 文章的结尾谈到， <span word="Ohayon">Ohayon</span>建议爱喝咖啡的人午饭后应该换喝脱咖啡因咖啡。另外，整个文章都在探讨咖啡因影响睡眠的机理，所以，作者大概会同意晚饭后不应该喝咖啡的说法。选项 <span word="A">A</span>是一个全称判断，这等于说所有喜欢喝咖啡的人都比不喝咖啡的人睡觉少。这不一定，因为如果咖啡适量，喝咖啡的时间适当，咖啡不会影响睡眠。所以，作者可能不会同意这种说法。根据文章第二段第二个句子，选项 <span word="C">C</span>是错的。根据文章第二段的第一个句子，我们体内褪黑激素 的浓度在我们上床时间前两个小时开始上升，而这个时候我们会开始有困意。反过来说就是，人们并非一有困意就睡觉。所以，选项 <span word="D">D</span>不是答案。 咖啡爱好者注意了。在深夜喝一杯快速提神的咖啡会严重影响你的睡眠，跟兴奋剂一样，咖啡因会扰乱褪黑激素的自由流动，这种褪黑激素是大脑里促人睡眠的一种荷尔蒙。 <span word="LotanShilo">LotanShilo</span>和<span word="Tel">Tel</span> <span word="Aviv">Aviv</span>大学<span word="Sapir">Sapir</span>医学中心的一组人员，在给六位志愿者做试验时发现，他们在饮了咖啡因的咖啡后比饮了脱咖啡因的咖啡后睡眼质量要差。平均来说，在喝了含咖啡因的咖啡后每晚睡眠时间336分钟，而喝了脱咖啡因的咖啡后则睡415分钟。同时他们得花半个小时入睡，是通常情况的两倍，另外，他们在床上辗转次数也要长一倍。 因为要花许多小时的时间才能将身体中的咖啡因除去， <span word="Ohayon">Ohayon</span>建议咖啡爱好者应在午后换喝脱咖啡因的咖啡。</p>
