A capital letter, a subject and a predicate, and an end mark: a complete sentence.
Complete Sentences
Every sentence is built from two halves. Work through each one, then test it on the line.
Subject
+
Predicate
What makes a sentence complete
The subject names who or what the sentence is about. The predicate tells what the subject does or is. Together they make a complete thought. A complete sentence also begins with a capital letter and ends with an end mark.
On the line
Mylittlesisterpaintedapicture.
A capital letter, a subject and a predicate, and an end mark: a complete sentence.
Now you try
Put a who or what together with what they do, open with a capital letter, and close with an end mark.
The subject: who or what
The orange half is the subject: who or what the sentence is about. Find it by asking who or what does the action.
On the line
Aloudsirenrang.
The subject is what the sentence is about: the siren.
Now you try
Pick a person, an animal, or a thing. That is your subject.
The predicate: what they do or are
The green half is the predicate: it tells what the subject does or is. The verb is the engine of the predicate.
On the line
Therunnersprintedaway.
sprinted tells what the runner did; away tells where.
Now you try
Add an action: ran, jumped, sang. The verb is the heart of the predicate.
Take a part away: a fragment
Remove the subject and you get "Raced down the hall." Raced who? Remove the predicate and you get "The whole soccer team." Did what? Each one is a fragment: a piece, not a complete thought. Doctor Noize sings it: give me a subject and a predicate, and if it is a complete thought, you can bet on it.
On the line
Thewholesoccerteam.
Fragment: no predicate. Did what? Add "cheered" and it is complete.
Now you try
Remove the subject or the predicate and the thought stops standing on its own. That is a fragment.
