Mr. Fu: Now what kind of animal is the tadpole? 蝌蚪是属于哪一类的动物？
Susie: A mammal! 哺乳动物！
Mr. Fu: No, Susie. Nice guess, but think harder. 错，苏西。猜得好，不过再努力想想。
Susie: Oh, wait...the one that can live in or out of the water. 喔，等等……是可以在水中跟离开水生活的那种。
Mr. Fu: Right. What do you call that kind of animal? 对。那种动物叫什么？
Susie: "Anibian"? 两楼动物？
Mr. Fu: [Laughs tenderly] That's cute. But I think it's pronounced "amphibian." （轻声笑）很可爱。不过我想正确发音是两栖动物。
Mr. Fu: And how does the tadpole breathe? 那蝌蚪要怎么呼吸？
Susie: With it's fins! 用鳍。
Mr. Fu: [Laughs again] No, sweetie. It doesn't have fins. It has... （再度笑）不是，亲爱的。蝌蚪没有鳍。它有……
Susie: Gills? 鳃？
Mr. Fu: Yes! You got it! You're so quick! Now tell me about your tadpole's progress... 是的！答对了！你的反应真快！现在告诉我你蝌蚪的进展……
Susie: Mine is growing very fast. I saw two little bumps coming out from behind its body. 我的蝌蚪长得很快。我看到它的身体后面长出两个小突起。
Mr. Fu: What do you think those might be? 你觉得那些可能是什么？
Susie: Are they warts? Oh, no! 是疣吗？喔，惨了！
Mr. Fu: I think those might be its hind legs, Susie. They grow first. 我想那应该是它的后腿，苏西。后腿会先长出来。
Susie: What's next? 接下来是什么？
Mr. Fu: Well, you will learn by watching yours grow. But if you want to know more now, you should read up on it. 这个嘛，只要看着你的蝌蚪长大，你就会了解。不过如果你现在想知道更多的话，你应该去找答案。
Susie: I can look it up on the Internet! 我可以去网络上查！
Mr. Fu: That's right. The more you learn about your pet, the better you can take care of it. 没错。你越了解你的宠物，你就越能把它照顾好。
