豆腐营养丰富且容易消化，老少咸宜。(perfect)

Tofu is rich in nutrition and easy to digest, and it is perfect for both the old and the young.

考查时态、形容词短语和并列结构。“豆腐营养丰富且容易消化” 处理为第一分句，主语 “豆腐” 用Tofu，“营养丰富且容易消化” 可译为be rich in nutrition and easy to digest，这里描述客观事实用一般现在时，系动词用is；“老少咸宜” 理解为 “对老年人和年轻人都是最佳的”，可处理为第二分句，补充主语it，译为it is perfect for both the old and the young，与第一分句之间是并列关系，用连词and连接。故翻译为：“Tofu is rich in nutrition and easy to digest, and it is perfect for both the old and the young.”。
