古时，有一人名为王冕，生性聪慧却家境贫寒。其父早逝，与母相依为命。王冕虽年幼，却深知读书之重要，常怀求知若渴之心。

一日，王冕见邻家有书可借，便每日往返于邻家，以求多读些许文字。然家中无灯油可供夜读，王冕遂于夏夜树下借萤火虫之光，冬日雪中借积雪反光而读书。如此数载，王冕学问渐长，终成一代饱学之士。

此故事告诉我们，无论环境如何艰难，只要心存志向，勤奋努力，皆能有所成就。王冕以其坚毅不拔的精神，成为后世学习的楷模。

翻译如下：

In ancient times, there was a man named Wang Mian who was intelligent but poor. His father died early and he lived with his mother. Although young, Wang Mian knew the importance of reading and had an eager desire for knowledge.

One day, Wang Mian saw that his neighbor had books he could borrow, so he went back and forth to the neighbor's house every day to read more texts. However, there was no oil for lamps at home to enable night study. Therefore, Wang Mian used the light of fireflies in summer nights and reflected light from snow in winter days to read. Over the years, Wang Mian's knowledge gradually increased and he eventually became a learned scholar.

This story tells us that no matter how difficult the environment is, as long as we have aspirations and work hard, we can achieve something. Wang Mian became a role model for learning due to his tenacity and perseverance.
