Sentences

A sentence is a word or group of words that expresses a complete thought. A sentence must have a verb in it.

I jog.(action verb)
The baby is cute.(linking verb)

We can classify sentences by the work they do. We say that there are four types of sentences: statements, questions, imperatives and exclamations.

I have a cat.(statement)
Is it raining?(question)
Stop!(imperative)
What a joke it is!(exclamation)

A statement gives us information. A statement begins with a capital letter and ends with a period.

George is tall.
Dr. Smith lives in Madison.

A question asks for information. A question begins with a capital letter and ends with a question mark.

How are you?
Where is Amy?

An imperative orders someone to do something. We often add please to make the order sound more polite. An imperative begins with a capital letter and ends with a period or an exclamation mark.

Please pass the butter.
Run!

An exclamation expresses strong feeling. An exclamation begins with a capital letter and ends with an exclamation mark.

What a beautiful house you have!
How friendly they are!
