Here's a breakdown:
* Declarative Sentence: A sentence that states a fact or opinion.
* Example: "The sky is blue."
* Exclamation Mark: A punctuation mark used to express strong emotions or to emphasize a statement.
When to Use an Exclamation Mark:
* Strong Emotion: You're feeling excited, surprised, angry, or any other intense emotion.
* Example: "That's amazing!"
* Emphasis: You want to highlight a particular point and make it stand out.
* Example: "Don't forget to bring your phone!"
* Surprise: You're expressing astonishment or disbelief.
* Example: "You won the lottery?!"
When NOT to Use an Exclamation Mark:
* Regular statements: If you're simply stating a fact or opinion, use a period (.).
* Example: "The sun rises in the east."
* Overuse: Using exclamation marks frequently can weaken their impact and make your writing seem childish or insincere.
In summary:
* Exclamation marks are for emphasis and emotion.
* Use them sparingly and strategically.
* A period is the default punctuation for declarative sentences.
