Here's a breakdown:
1. Declarative Sentences:
* Statements of fact: These sentences simply state something that is true.
* Example: "The sky is blue."
* Statements of opinion: These sentences express a personal belief or view.
* Example: "I think pizza is the best food."
* Simple sentences: These are complete sentences with a subject and a verb, expressing a single thought.
* Example: "The cat sat on the mat."
2. Imperative Sentences:
* Commands or requests: These sentences tell someone to do something. While they often sound like commands, they can also be polite requests.
* Example: "Please close the door."
* Example: "Go to bed now."
3. Interrogative Sentences:
* Questions: These sentences ask for information. These are NOT generally ended with a period. They use a question mark instead.
* Example: "What is your name?"
4. Exclamatory Sentences:
* Expressions of strong emotion: These sentences express excitement, surprise, or other strong feelings. These are NOT generally ended with a period. They use an exclamation mark instead.
* Example: "Wow! That was amazing!"
Important note: Periods can also be used within a sentence to separate independent clauses, when they are connected by a conjunction (for example, "and," "but," or "or").
Example: "The sun was shining brightly, and the birds were singing."
