爷爷和孙子在公园里散步,他们来到了一口池塘边。许多孩子在那里玩他们的遥控小船。孙子看着那些亮闪闪的小船,看着那些孩子如何用它们比赛,激起浪花,小船彼此追逐着。场面看起来可真是乐趣十足。他可以听到其他孩子的笑声和叫声,而他却觉得心情沉重。 Grandpa and grandson walking in the park, they came to a pond. Many children play there with their remote control boats. The grandson looked at the shining boats, watched how the children used them to race, provoked waves, and the boats chased each other. The scene looks really fun. He could hear the laughter and cry of other children, and he felt a heavy feeling.
