Instead of receiving the standard care given to lab animals, the 60% group was watched over by a newcomer to the lab who, Kelli writes, "handled the animals differently. When she fed her rabbits she talked to them and petted them. She didn't just pass out food, she gave them love. The studies indicate something is missing in the traditional biomedical model. It wasn't diet or genetics that made a difference in which rabbits got sick and which stayed healthy. It was kindness."
并非接受给予实验动物的标准照料，60%的小组被实验室的一名新来者照管，Kelli写道，“她以不同的方式处理动物。当她喂她的兔子时，她和它们说话并抚摸它们。她不只是分发食物，她给予它们爱。研究表明传统生物医学模型中缺少某些东西。不是饮食或基因导致哪些兔子生病以及哪些保持健康的差异。是善意。”
短语动词 "pass out" 在本句中表示「分发」，是及物用法，宾语 "food" 后置。这是该短语动词的核心义项之一，常用于分发物品、材料等场景。
识别要点："pass out" 后接具体名词作宾语时，宾语可以后置（如本句 "pass out food"）或插入两词之间（如 "pass food out"）。当宾语为代词时，通常必须插入（如 "pass it out"）。
与「昏倒」义项的区分：当 "pass out" 表示「昏倒/失去知觉」时，通常作不及物动词使用，不接宾语，如 "He passed out from exhaustion"。本句中明确有宾语 "food"，且语境为喂养动作，因此只能理解为「分发」义项。
本句将 "pass out food"（分发食物）与 "gave them love"（给予关爱）形成对比，强调前者是机械的物质给予，后者包含情感互动。这种对比凸显了 "pass out" 作为「分发」时的中性、程序化特征。
