3. 瑶瑶用便利贴记录了她最喜欢的动物——青蛙的成长过程，但便利贴被弄乱了。你能帮她把顺序整理好吗？
① Baby Justin lives in the river. He is small and black.
（
③
） Later, he has four legs. His tail is small and short.
（
④
） Now Justin has no tail. He has a big mouth and he can catch flies.
（
②
） Soon he has a round head and a long tail.
答案：② Soon he has a round head and a long tail.
③ Later, he has four legs. His tail is small and short.
④ Now Justin has no tail. He has a big mouth and he can catch flies.
顺序：①→③→④→②
解析：青蛙成长过程为：卵→蝌蚪（小而黑，生活在河里，圆头长尾）→长出后腿和前腿（有四条腿，尾巴变短）→尾巴消失（无尾，大嘴，会捉苍蝇），故顺序为①→③→④→②。
