Here's the breakdown:
1. Subject: Who or what is the sentence about?
2. Verb: What is the subject doing?
3. Object: (Optional) What is the subject acting upon?
Here are some examples:
* The cat sat on the mat. (Subject: cat, Verb: sat, Object: mat)
* My favorite color is blue. (Subject: color, Verb: is, Object: blue)
* The sun is shining brightly. (Subject: sun, Verb: is shining, Object: brightly)
* I love to eat pizza. (Subject: I, Verb: love, Object: to eat pizza)
Key things to remember:
* Simple structure: Declarative sentences are usually simple and direct.
* Period at the end: They always end with a period.
* Statement of fact: They state something as a fact, even if it's an opinion.
Now you can write your own declarative sentences!
