同学你好~
on the way traveling → during his journey
更简洁且符合语境。

His parents had been worrying about him → His parents had been worried about him
had been worried更符合时态和语境。

they learned that their son was sent safely → they learned that their son had been sent home safely
补充 home，使句子更完整；使用 had been sent 符合过去完成时。

when the boy reached → when he arrived
arrived 更符合英语表达习惯。

he felt so sorry, he was put to shame to his parents→ he felt deeply sorry and ashamed of his actions
避免重复 to his parents，使表达更清晰。

he was afraid that he was punished → he was afraid that he would be punished
使用 would be punished表示将来时态。

To his surprised → To his surprise
surprise 是名词形式，正确表达应为 to his surprise。

the boy given him a hero’s welcome → the boys gave him a hero’s welcome
复数

him adventure experience → his adventurous experience
使用 his 代替 him

The headteacher decided that he was punished making a talk →The headteacher decided that he would be punished by making a talk
注意时态和介词by

祝同学学习进步~
