In the first chapter we establish how this civilization functions. The boys shot down over the
tropical island where the novel takes place, so you may visualize this island, whatever you feel like picturing there, it doesn't just have to be the thing written. I would for example imagine the smell of the sea. The boys are between civilization and savagery here and that is the main conflict in the novel.
an direct object is the thing being acted upon by the verb.
the object of a preposition is a noun, noun phrase, or pronoun that follows a preposition and completes its meaning. The object of a preposition is in the objective case. A word group made up of a preposition, its object, and any of the object's modifiers is called a prepositional phrase.
Alliteration describes when there is a repetition of a letter or sound with connected words.
(EX: Pickled, Peter, Peppers...)
