夏天到了，天气热得让人什么事情都不想做。但是我们应该对夏天充满兴趣，对生活充满兴趣。杰克从一开始的无趣，不知道该做些什么，后来去拯救老鹰，突然间又有事做了。所以生活的乐趣需要我们自己去发现。
Summer is coming, and the weather is so hot that people don't want to do anything. But we should be interested in summer and in life. Jack was bored from the beginning, not knowing what to do, then went to save the Eagle, and suddenly he had something to do. So the joy of life needs to be discovered by ourselves.
