61. staying　此处是动名词短语作主语，故填staying。

62．which　 此处是energy作先行词，后面是一个非限制*定语从句，从句缺少主语和引导词，故填which。

63．in　 result in导致，产生。句意：这引起重量增加。

64．comfortable　形容词修饰名词，故填comfortable舒适的。　

65．are exposed　 在这里Outdoor workers是先行词，和expose之间是被动关系，根据句意可知用一般现在时态的被动语态，故填are exposed。

66．a　句意：有大量棕*脂肪。a significant amount of大量的。

67．compared 　句意：当与同龄的户内工人相比较的时候。compared to/with...，与……相比较。

68．One　 根据前面一句two different control groups of mice，可知这里是其中的一组，故填one。

69．lower　根据句中的than，可知用比较级，故填lower。

70．possibly　副词修饰动词，故填possibly。
