blade
A few minutes later the student came back. The teacher asked, "Well, I don't see a beautiful blade of grass in your hand." The student said, "On my journey, I found quite a few beautiful blades of grass, but I thought that I would find a better one, so I didn't pick it. But I didn't realize that I was at the end of the field, and I hadn't picked any because you told me not to go back, so I didn't go back." The teacher said, "That's what will happen in real life."
几分钟后，学生回来了。 老师问到："我看你手上没有漂亮的草呀。" 学生回答说："我在路上发现了许多漂亮的草，但是我觉得我会找到更好的，于是就没有把它拔下来。但我没有意识到我已经走到了草地的尽头，因为你告诉我不要往回走，所以我一颗也没有拔。" "这就是生活中经常发生的情况。"老师说到。
