Subject and verb agreement is an essential aspect of English grammar that can often be overlooked, leading to confusion and misunderstandings. The concept of subject-verb agreement is relatively simple: the subject of a sentence must agree with the verb in number and person. This means that if the subject is singular, the verb must be singular, and if the subject is plural, the verb must be plural as well.

To master the art of subject-verb agreement, it is important to practice regularly with varying sentence structures. Practice 1 is an excellent way to get started. In this exercise, you will be provided with a series of sentences in which the subject and the verb do not agree. Your task is to identify the error and correct it by changing the verb to agree with the subject.

Example:

Incorrect: The pair of shoes are comfortable.

Correct: The pair of shoes is comfortable.

Here, `pair of shoes` is a singular subject, so the verb `is` should be used instead of `are.`

Let`s take a look at some more examples:

1. Incorrect: The book on the table is one of my favorites.

Correct: The book on the table is one of my favorites.

The subject of this sentence is `book,` which is singular, so the verb `is` is correctly used.

2. Incorrect: The dogs in the yard barks at every passerby.

Correct: The dogs in the yard bark at every passerby.

The subject of this sentence is `dogs,` which is plural, so the verb `bark` is correctly used.

3. Incorrect: The group of friends always talks at the same time.

Correct: The group of friends always talk at the same time.

The subject of this sentence is `group of friends,` which is singular, so the verb `talks` should be used instead of `talk.`

4. Incorrect: The boys in the class is preparing for their exams.

Correct: The boys in the class are preparing for their exams.

The subject of this sentence is `boys,` which is plural, so the verb `are preparing` is correctly used.

5. Incorrect: The list of items were misplaced.

Correct: The list of items was misplaced.

The subject of this sentence is `list,` which is singular, so the verb `was` should be used instead of `were.`

By consistently practicing exercises like these, you can train your mind to identify subject-verb agreement errors easily, and this will help you communicate effectively in writing. It`s always good to have a thorough understanding of English grammar rules to avoid errors that can negatively impact your credibility as a writer.
