Final answer:
Subordinating conjunctions are used to join a dependent clause to an independent clause, completing the sentence and adding complexity. Examples with conjunctions like 'since,' 'although,' and 'after' show this in practice with references to Edgar Allan Poe's life and his story 'Tell-Tale Heart'.
Step-by-step explanation:
When constructing sentences with subordinating conjunctions, it's essential to pair the dependent clause introduced by the conjunction with an independent clause to complete the thought. Here are completed examples for each given sentence:
- Since Edgar Allan Poe had a troubling life, his writings often reflect themes of darkness and mystery.
- Although the narrator in 'Tell-Tale Heart' hides his evil crime, his guilt manifests through his own paranoia and ultimate confession.
- After the main character in 'Tell-Tale Heart' hides the body, he is haunted by the relentless beating of the old man's heart.
The effective use of subordinating conjunctions adds depth to writing by linking two ideas in a way that emphasizes the importance of one over the other. Remember that the dependent clause cannot stand alone and must be accompanied by an independent clause to form a complete sentence.
