It’s a night. John is looking at the sky.
Tom is John’s younger brother. He asks John“ What are you doing?”
John says,“ I’m counting stars.”
Tom laughs and says,“ It’s really dark now. Why not count them tomorrow morning?”
这是一个晚上。约翰抬头看着天空。
汤姆是约翰的弟弟。他问约翰：“你在干什么？”
约翰说：“我在数星星。”
汤姆笑着说：“现在天空太黑了。你为什么不等到明天早上再数呢？”
