26、。有一种脂肪叫作棕色脂肪，当人处于寒冷环境中，它可以燃烧卡路里从而减轻体重。1staying解析：分析句子结构可知，此处是非谓语动词作主语，表示一种抽象性、一般性的动作，所以应用动名词形式。故填staying。2which/that解析：分析句子结构可知，_produces heat and keeps us warm是定语从句，从句中缺少主语，且先行词指物，所以应用关系代词which/that。3in解析：句意：白色脂肪储存额外的能量，这会导致体重增加。result in为固定短语，意为“导致；造成”。故填in。4comfortable解析：所填词和constant并列作temperatur

27、es的定语，所以应用形容词。故填comfortable。5are_exposed解析：定语从句中缺少谓语，expose与先行词之间是被动关系，且表示一般情况，所以应用一般现在时的被动语态，又因who代指workers，所以根据主谓一致原则应填are exposed。6a解析：a significant amount of意为“大量的”。故填a。7compared解析：句中已有谓语动词have，故设空处应用非谓语动词，compare与其逻辑主语Outdoor workers之间是被动关系，所以应用过去分词。故填compared。8lower解析：根据空后的than可知，此处用比较级，修饰名词levels应用形容词，故填lower。9prevention解析：and连接并列成分，由此可判断此处应填prevention作into的宾语。10possibly解析：修饰动词lose应用副词，故填possibly。
