Chapter 15 The Tadpole and the Frog

“BE ashamed of yourself,” said the frog.

“When I was a tadpole¹, I had no tail.”

“Just what I thought!” said the tadpole.

“You never were a tadpole.”

1 tadpole   

n.[动]蝌蚪

参考例句：

• As a tadpole changes into a frog,its tail is gradually absorbed.蝌蚪变成蛙，它的尾巴就逐渐被吸收掉。
• It was a tadpole.Now it is a frog.它过去是蝌蚪，现在是一只青蛙。
