成语故事：囊萤夜读 Idiom Story: Reading by Firefly Light

城里的小朋友一般都有很好的学习条件，但应该让他们知道，其实不仅古代有很多穷人家的孩子没有条件学习，就在今天，还有一些小朋友生活和学习的条件很差。要珍惜自己的好条件，要关心那些需要帮助的孩子。

Children in the city generally have excellent conditions for learning. However, they should be made aware that not only in ancient times many children from poor families did not have the conditions to learn, but even today some children have poor living and learning conditions. They should cherish their good conditions and care for those children who need help.
