Correct or improve the translation of the following English sentences.原文:At its simplest, clean eating is about ingesting nothing but"whole" or "unprocessed" foods.译文:最简单地讲,清洁饮食指摄入“完整的”或“未加工的”食品。
【正确答案】:

最简单地讲,清洁饮食指仅摄入“天然健康的”或“未加工的”食品。


【题目解析】:本题考查对“nothing but”和“whole”的正确理解与翻译。nothing but是固定用法意为“仅仅”,形容词whole“完整的”此处用于形容foods“食物”,意译为“天然健康的”更合适。
