How does school go, lad? asked Grandfather as they progressed around the Planty.

你们的学校生活如何？爷爷一边询问，一边绕着林荫大道行走。

They really are planty powerhouses that strengthen the body in many different ways, including mentally.

它们确实是植物强者， 可以通过多种不同方式（包括精神） 增强身体。

So, laughing and chatting, the three walked along. Twice every day Grandfather and his rake made a complete circuit of the Planty.

他们一边走着一边欢笑，一边聊天，每天两次，爷爷都会拿着靶子围绕林荫大道一圈。

It takes just one hour to walk about the boulevard (or Planty as it is called), and all that time one is walking under great shade trees.

漫步这条大道只需要一个小时（人们把林荫大道叫作“Planty”），人们会一直走在巨大的林荫树下。
