Subject-Verb Agreement — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The teacher writes the lesson on the whiteboard.
The subject 'The teacher' is singular, so the verb takes the singular form 'writes' with the -s ending.
2. My cousins visit us every summer for a week.
The subject 'My cousins' is plural, so the verb uses the base form 'visit' without an -s ending.
3. The baby cries when she is hungry or tired.
The subject 'The baby' is singular, so the verb takes the singular form 'cries' with the -ies ending.
4. Those clouds in the sky look very dark today.
The subject 'Those clouds' is plural (the prepositional phrase 'in the sky' does not change the subject), so the verb uses 'look.'
5. He has three pets at home: a dog, a cat, and a fish.
The subject 'He' is singular, so the verb takes the singular form 'has' instead of 'have.'
6. The frogs in the pond croak loudly at night.
The subject 'The frogs' is plural (the prepositional phrase 'in the pond' does not change the subject), so the verb uses 'croak.'
7. Our neighbor plants flowers in her garden every spring.
The subject 'Our neighbor' is singular, so the verb takes the singular form 'plants' with the -s ending.
8. The buses take the children home after school.
The subject 'The buses' is plural, so the verb uses the base form 'take' without an -s ending.
9. That window is stuck and will not open.
The subject 'That window' is singular, so the linking verb takes the singular form 'is.'
