Study Guide – Sentences
A sentence is a group of words that makes a complete thought. It always begins with a
capital letter and usually ends with a period. Example: When you finish your homework
we can play ball.
A fragment is a separated part of a sentence that does not make a complete thought.
Example: When you finish your homework.
A declarative sentence makes a statement. It ends with a period.
Example: Spiders have eight legs.
An interrogative sentence asks a question. It ends with a question mark.
Example: How many legs do most insects have?
An imperative sentence gives a command or makes a request. It ends with a period.
Example: Please put the paper in the pile.
An exclamatory sentence shows sudden or strong feeling. It ends with an exclamation
point. Example: Watch out for that car!
Sentences can be either long or short, but good sentences should be interesting.
Example: My dog is fun. (boring)
My puppy likes to catch a rubber ball with his teeth. (interesting)
A run-together sentence is a poorly written sentence containing too many ideas joined
by and, and so, or and then.
Correcting a run-together sentence
Example: The young boy wanted to give something to Jesus and so he offered Him his lunch.
Corrected: The young boy wanted to give something to Jesus. He offered Him his lunch.
Another way to correct run-together sentences
when, or while
Example: The young boy wanted to give something to Jesus and so he offered Him his lunch.
Corrected: Since the young boy wanted to give something to Jesus, he offered Him his
lunch.
