A declarative sentence makes a statement or provides information, while an imperative sentence gives a command or instruction. Declarative sentences usually end with a period, while imperative sentences often end with a period or exclamation mark.
This sentence is a declarative sentence because it is making a statement.
To change a declarative sentence into an exclamatory sentence, simply add an exclamation mark at the end of the sentence. For example, changing "The sky is blue" to "The sky is blue!" adds an exclamatory tone to the statement.
Puntuation
To change a declarative sentence into a question, you can typically add a question word (who, what, when, where, why, how) at the beginning of the sentence, invert the subject and the verb, or add a question mark at the end.
