生物にはふしぎな力がある。例えば、植物は生きる力がとても強い。切り取った茎を土にさしておくだけで、あっという間に元の大きさに成長することもあるほどだ。動物にも似たことが起こる。トカゲのしっぽやかにのはさみは、なくなると新しく生えてくる。しかし、人間の指はなくなると、二度と元には戻らない。ただ、髪の毛や手の爪は切ってもまた伸びる。このように、生物には切り取られた体の一部を、元に戻す力があるのだ。

Living things have mysterious abilities. Plants, for example, have an extremely strong ability to survive and grow. Some plants can grow back to their original size in no time simply by placing a cut stem in the soil. Similar things happen with animals as well. If a lizard loses its tail or a crab loses a claw, a new one grows back. However, if a human loses a finger, it will never grow back. Still, our hair and fingernails grow again even after being cut. In this way, living things have the ability to restore parts of their bodies that have been cut off.
