There are four types of sentences:
- The Statement. These sentences convey a fact and end with a full stop. For example: Wendy is taller than Sue. The Nile is the world’s longest river.
- The Question. Such sentences require an answer and end with a question mark. For example: How old is your dog? What is today’s date? When a question is asked in such a way as not to require an answer, it is known as a rhetorical question.
- The Command. As the name suggests these are orders to be obeyed and, therefore, they often end with an exclamation mark. For example: Halt! Wash your hands, at once!
- The Exclamation. Exclamations are spontaneous expressions that denote a sudden impulse. For example: Ouch! Help! Oh, what a beautiful morning!
