【正确答案】 1、正确答案：The advantage of school education is not merely the imparting of knowledge, but, more importantly, the opportunities it affords us for making friends. I did not realize that until I had left school. In recent years, I had begun to understand that more deeply, only to regret having spent time too carelessly at that time unconsciously. Recently, when seeing young students walking with bags, in twos and threes hand in hand or arm in arm, I would envy their joy and comfort of friendship, giving my best wishes to them from the bottom of my heart.
