Jo glanced at the sheet and saw a pleasing illustration composed of a lunatic, a corpse, a villain, and a viper.

乔瞄了眼，看到这张纸上有很引人注目的画，上面疯子、具尸体、恶棍和条蝮蛇。

For 10 months of the year there is nothing substantial to eat on the island, so the reptiles conserve their energy by barely moving at all.

年中有十月，岛上没有什么吃的，所以蝮蛇几乎不移动以保存能量。

The dropped meal is tracked down mainly by smell, the viper using its forked tongue to taste the air until it is close enough to see its quarry.

蝮蛇利用嗅觉落的食物，利用它叉开的舌头品尝着空气直到近得可以看见猎物。

They hatch the eggs of vipers and spin a spider's web. Whoever eats their eggs will die, and when one is broken, an adder is hatched.

他们抱毒蛇蛋，结蜘蛛网，人吃这蛋必死。这蛋被踏，必出蝮蛇。
