If a man keeps cherishing his old knowledge, so as continually to be acquiring new, he may be a teacher of others.

语音讲解：

今日发音练习重点：

1. continually发五个音节，第二音节重读；

2. man的发音英美略有差异。

言之有物：

1. keep doing XX 持续/重复做...

I keep telling you, but you won’t listen!

我一再跟你说，但你就是不肯听！

Keep smiling! 要保持笑容！

→keep cherishing one's old knowledge 保持对旧知识的珍惜/珍爱 → 温故

“温故”没有使用常见的review等词，译者理雅各（James Legge）选用“cherish”含有“珍爱、珍惜”的意思；汉学家亚瑟·威利译选用“reanimate”具有“使得老的知识获得新的力量”的意思。

2. cherish v. 珍爱；怀念

Cherish the memory of those days in Paris.

怀念在巴黎的岁月。

回顾【cherish the memory of sth】

3. →acquire (one's) new (knowledge) 获得新的知识→ 知新

A teacher should teach students how to acquire knowledge.

老师应该教导学生怎么去获取知识。

4. 词链儿：so as to do XX 为了做某事，以便做某事

so as continually to do XX 为了持续不断地做某事

温故而知新，可以为师矣：出自孔子的《论语》为政篇，意思是温习旧知识从而得知新的理解与体会，凭借这一点就可以成为老师了。说明人们的新知识、新学问往往都是在过去所学知识的基础上发展而来的道理。
