劝学原文全文：

《劝学》是唐代大诗人白居易的一首诗，全文如下：

众里寻他千百度，

蓦然回首，那人却在，

灯火阑珊处。

这首诗表达了对知识的追求和劝诫。诗中的“那人”指的是知识，作者在追寻知识的过程中，经历了千辛万苦，但最终还是找到了它。诗末的“灯火阑珊处”则是指知识的殿堂，是作者追求知识的终点。

诗中的“众里寻他千百度”是一个广为人知的成语，用来形容追求目标的艰辛和不易。这句话也可以理解为，要想获得知识，必须付出艰辛的努力和不断地探索。而“蓦然回首，那人却在”则是在告诫我们，在追求知识的过程中，不要迷失方向，也不要失去信念。

这首诗的意义不仅仅在于对知识的追求和劝诫，更在于对人生的启示。追求知识不仅能够让我们更加博学多才，还能够让我们更加坚韧不拔，不轻言放弃。在学习的道路上，我们需要时刻保持对知识的热爱和追求，不断地学习、探索、积累，才能够不断地提升自己的能力和素质，实现自己的人生价值。

译文：

In Search of Knowledge

A thousand times I searched for knowledge

And when I turned around, I found it

In the flickering light of a lamp.

This poem by the Tang dynasty poet Bai Juyi expresses his pursuit of knowledge and his advice to others. The “knowledge” he refers to is personified as “that person” in the poem. Bai Juyi tells us that in his pursuit of knowledge, he faced countless difficulties and hardships, but he eventually found it. The “flickering light of a lamp” at the end of the poem represents the hall of knowledge, which is the ultimate destination of his pursuit.

The phrase “A thousand times I searched for knowledge” has become a famous idiom in Chinese, expressing the difficulty of pursuing a goal. It also implies that we must make great efforts and explore constantly to acquire knowledge. The line “And when I turned around, I found it” is a reminder that we should not lose our direction or faith in the pursuit of knowledge.

This poem not only emphasizes the importance of pursuing knowledge, but also provides inspiration for life. Pursuing knowledge can not only make us more knowledgeable and versatile, but also more persevering and tenacious. In the pursuit of learning, we need to maintain our passion and pursuit of knowledge, continue to learn, explore, and accumulate, in order to constantly improve our abilities and qualities, and realize our own life values.
