Subject-verb agreement is crucial in ensuring that a sentence is grammatical, clear, and easy to understand. One common mistake that writers make is not matching their subject with the appropriate verb tense. In this article, we will examine which sentence correctly uses subject-verb agreement, specifically with reference to the name “Tommy.”

To understand how to use subject-verb agreement correctly, we first need to understand what it means. Subject-verb agreement refers to the idea that the verb in a sentence must match the subject in terms of tense, number, and person. For example, if the subject is singular, the verb must also be singular; if the subject is plural, the verb must be plural.

Now let`s look at the following sentences, all of which contain the name “Tommy”:

1. Tommy runs fast.

2. Tommy run fast.

3. Tommy have been running fast.

4. Tommy has been running fast.

Out of these four sentences, only one correctly uses subject-verb agreement. Let`s analyze each sentence to see which one it is.

Sentence 1: Tommy runs fast.

This sentence is correct because the subject “Tommy” is singular, and the verb “runs” matches it in tense and number. Therefore, this sentence uses subject-verb agreement correctly.

Sentence 2: Tommy run fast.

This sentence is incorrect because the subject “Tommy” is singular, but the verb “run” is plural. It should be “Tommy runs fast” instead.

Sentence 3: Tommy have been running fast.

This sentence is incorrect because the verb “have” is plural, but the subject “Tommy” is singular. It should be “Tommy has been running fast” instead.

Sentence 4: Tommy has been running fast.

This sentence is correct because the subject “Tommy” is singular, and the verb “has been” matches it in tense and number. Therefore, this sentence uses subject-verb agreement correctly.

In conclusion, the correct sentence that uses subject-verb agreement with the name “Tommy” is: “Tommy runs fast.” Remember, when writing any sentence, it is crucial to ensure that your subject and verb match in tense, number, and person to avoid any grammatical errors. By being mindful of subject-verb agreement, you can improve the clarity and effectiveness of your writing, making it more engaging for your readers.
