You can find a number of similes in the third part of Ray Bradbury's Fahrenheit 451 if you know how to spot them.
Similes are a specific literary device that draw direct comparisons using “like” or “as.” This differentiates them from metaphors, which eliminate the use of a preposition and directly compare two items by equating them. A simile would say a plane is like a bird; a metaphor would say a plane is a bird. Or the metaphor would bypass stating that a plane is a bird, and just name the plane “bird,” as in, “The metal bird full of people glided beneath the clouds.” Both of these forms of comparison are used often and sometimes together in literature, so make sure you find “like” or “as” in any comparison you identify as a simile.
In Fahrenheit 451, Bradbury uses metaphor and simile in combination. For example, in this passage that begins on page 117 and continues on page 118, Bradbury compares a highway to a river using simile, and then to a stage using metaphor.
