答案

参考答案:D

解析:

[分析]: 是非判断。 题干:根据文章,关于第一次研究,哪个说法不正确a选项为“超过 1,000人参与了该研究。”;根据原文“researchers…examined information on more than one thousand people.”,译文为;研究人员调查了超过1,000人的信息,所以该选项是正确的。b选项为“睡眠较少的人ghrelin的血压高。”,根据原文“Some people slept less…They had fifteen percent higher blood levels of a hormone called ghrelin…”,译文为:睡眠较少的人他们的一种荷尔蒙ghrelin的血压高出15 %。所以该选项是正确的。c选项为“睡眠较多的人leptin的血压高。”,根据原文“…people slept less…they had fifteen percent less of the hormone leptin.”,译文为:睡眠较少的人荷尔蒙leptin低于正常人15%。由此可以推断睡眠多的人该项指标高,所以该选项正确。d选项为“运动量能够影响研究的结果。”,根据原文“The results were not affected by how much people exercised.”,译文为:结果并不受人们运动量的影响。所以该选项是错误的。
