The subject-verb agreement is an essential grammar rule that ensures the subject and verb in a sentence match in number, meaning singular subjects are paired with singular verbs, and plural subjects with plural verbs. Let's analyze and ensure each sentence follows this rule:
The players run around the field.
This sentence is correct. 'Players' is a plural subject, and 'run' is the plural form of the verb.
My sister and I go to the same school.
This sentence is correct. The phrase 'My sister and I' is a plural subject, and 'go' is the plural form of the verb.
He eats his lunch quickly.
This sentence is correct. 'He' is a singular subject, and 'eats' is the singular form of the verb.
The bouquet of flowers smells nice.
This sentence is correct. The subject 'bouquet' is singular, so it takes the singular verb 'smells'. The phrase 'of flowers' is a prepositional phrase and does not affect the singular nature of the subject.
Our teacher gives us assignments every day.
This sentence is correct. 'Teacher' is a singular subject, and 'gives' is the singular form of the verb.
In summary, the sentences you provided already adhere to correct subject-verb agreement. Just ensure that the subject and verb agree in number, and you will consistently compose grammatically correct sentences.
