The parallel structure refers to the repetition of a chosen grammatical form within a sentence. It uses word, phrases or clauses that are grammatically similar or identical in structure, sound, meaning, or meter, in order to show that the ideas are equally important and to give a certain flow while reading the piece of writing.
The sentence "I enjoy eating and cooking" contains this construction because both "eating" and "cooking" are the same type of word: gerunds.
Gandalf gets Beorn to shelter thirteen dwarves by bringing them in two by two while he tells an exciting story. ... the mention of the dwarves being attacked by Goblins eventually interests about the dwarves. Beorn doesn't like Goblins or the wolves.
