成为单词的人名：Luigi Galvani
Luigi Galvani (9 September 1737–4 December 1798) was an Italian physician, physicist, biologist and philosopher, who discovered animal electricity. He is recognized as the pioneer of bioelectromagnetics. In 1780, he discovered that the muscles of dead frogs’ legs twitched when struck by an electrical spark. This was one of the first forays into the study of bioelectricity, a field that still studies the electrical patterns and signals from tissues such as the nerves and muscles.

修辞概念： allegory
As a literary device, an allegory is a metaphor in which a character, place or event is used to deliver a broader message about real-world issues and occurrences. Allegory (in the sense of the practice and use of allegorical devices and works) has occurred widely throughout history in all forms of art, largely because it can readily illustrate or convey complex ideas and concepts in ways that are comprehensible or striking to its viewers, readers, or listeners.
One of the most famous examples of allegory in history is Plato’s Allegory of the Cave, in which a group of people is chained inside a cave and sees only shadows of the outside world projected on the wall of the cave. One person escapes the cave and is able to see reality for the first time. However, upon reentering the cave and trying to describe the outside world, the people still chained to the wall reject this other interpretation and vision. Plato’s allegory is meant to symbolize the difficulty of the philosopher’s task when trying to expand the worldview of the common man.
