- Subjective Verb Agreement
Verbs must agree with subjects in number and in person (1st/2nd/3rd). A subject is a noun or pronoun . A verb is an action performed by the subject. In the following section, we will see many such examples of the Subjective Verb concept. We also have exercises that will help you cement the concept of Subjective Verb in a proper way.

Verbs must agree with subjects in number and in person (1st/2nd/3rd). Subjects and verbs must agree in number. This is the cornerstone rule that forms the background of the concept. For example, consider this: The dog growls when he is angry. The dogs growl when they are angry.
Following is a roadmap or rules that you can follow to avoid any mistakes in the Subject-Verb Agreement:
Don’t get confused by the words that come between the subject and verb; they do not affect agreement . The dog, who is chewing on my jeans, is usually very good.
Prepositional phrases between the subject and verb usually do not affect agreement. For example, The colours of the rainbow are beautiful.
When sentences start with “there” or “here,” the subject will always be placed after the verb, so care needs to be taken to identify it correctly. For example, “There is a problem with the balance sheet . Here are the papers you requested.”
Subjects don’t always come before verbs in questions. Make sure you accurately identify the subject before deciding on the proper verb form to use. For example: Does Lefty usually eat grass? Where are the pieces of this puzzle .
If two subjects are joined by and, they typically require a plural verb form. Example: The cow and the pig are jumping over the moon.
The verb is singular if the two subjects separated by and refer to the same person or thing. For example: Red beans and rice is my mom’s favorite dish.

If the words each, every, or no come before the subject, the verb is singular. No smoking and drinking is allowed. Every man and woman is required to check in.
If the subjects are both singular and are connected by the words or, nor, neither/nor, either/or, and not only/but also the verb is singular. For example: Jessica or Christian is to blame for the accident.
The only time when the object of the preposition factors into the decision of plural or singular verb forms is when a noun and pronoun subjects like some, half, none, more, all, etc. are followed by a prepositional phrase. In these sentences, the object of the preposition determines the form of the verb. For example: All of the chicken is gone. All of the chickens are gone.
The singular verb form is usually used for units of measurement . For example: Four quarts of oil was required to get the car running.
If the subjects are both plural and are connected by the words or, nor, neither/nor, either/or, and not only/but also, the verb is plural. For example: Dogs and cats are both available at the pound.
If one subject is singular and one plural and the words are connected by the words or, nor, neither/nor, either/or, and not only/but also, you use the verb form of the subject that is nearest the verb. For example: Do your sisters or your girlfriend want any pizza?
Indefinite pronouns typically take singular verbs. Example: Everybody wants to be loved. Except for the pronouns (few, many, several, both) that always take the plural form. For example: Few were left alive after the flood.
If two infinitives are separated by and they take the plural form of the verb. For example: To walk and to chew gum require great skill.
When gerunds are used as the subject of a sentence they take the singular verb form of the verb, but when they are linked by and they take the plural form. Example: Standing in the water was a bad idea. Swimming in the ocean and playing drums are my hobbies.
Collective nouns like the herd, senate, class, crowd, etc. usually take a singular verb form. Example: The herd is stampeding.
Titles of books, movies, novels, etc. are treated as singular and take a singular verb. For example: The Burbs is a movie starring Tom Hanks.
Final Rule – Remember, only the subject affects the verb!
Prepositional Phrases and Why They Matter
Example: The boxes of cake mix are on the shelf.
The verb is “are,” but what is the subject? Is it “boxes” or “cake mix”? In order to figure out the subject, we must eliminate the prepositional phrase which is often times in between the subject and the verb.
A prepositional phrase is a two – to four – word phrase (sometimes more) that begins with a preposition (above, among, at, below, beneath, between, in, of, over, to, under). A verb must agree with its subject, not with the object of a prepositional phrase, which often comes between the subject and the verb.
Since “of” is a preposition, we ignore the prepositional phrase “of cake mix.” Therefore, “boxes” is the plural subject, which matches perfectly with the plural verb “are.”
Practice Questions:
Q 1: Everyone (has/have) done his or her homework.
Q 2. Each of the students (is/are) responsible for doing his or her work.
Q 3. Either my father or my brothers (is/are) going to sell the car.
Q 4. Neither my sisters nor my mother (is/are) going to sell the house.
Q 5. The samples on the tray in the lab (need/needs) testing.

Q 8. Neither the dogs nor the cat (is/are) very hungry.
Q 9. Either the girls or the boy (walk/walks) in the evening.
Q 10. Either the boy or the girls (walk/walks) in the evening.
Q 11. At the end of the fall (comes/come) the hard tests.
Q 12. The slaughter of animals for their fur (has/have) caused controversy.
Q 13. The student, as well as his teacher, (was/were) going on the field trip.
Q 14. The hard tests (comes/come) at the end of the fall.

Present Perfect Tense
Introduction.
The Present Perfect Tense is an integral part of English grammar which is essential to understand and use correctly. This tense form is generally associated with actions in the past but are not definitive in nature, such as events that have happened at unspecified times, or actions that started in the past and continue up to the present.
Table of Contents
Understanding the Present Perfect Tense
To begin understanding the Present Perfect Tenses, you should know that it is made up of two elements: the present tense of the verb ‘to have’ (have/has) and the past participle of the main verb.
- I have bought a new car.
- They have arrived at the station.
- She has eaten all the cookies.
Types of Present Perfect Tense
There are mainly two types of Present Perfect Tenses:
Present Perfect Simple
Present perfect continuous.
The Present Perfect Simple is formed using the structure:
Subject + have/has + past participle of the verb
This tense is commonly used to talk about an action in the past without specifying when it happened, to say that an action which started in the past continues in the present and even to focus on the result of a past action.
- I have visited London three times.
- She has lived here all her life.
- They have done their homework.
The Present Perfect Continuous is formed using the structure:
Subject + have/has + been + verb + ing
This tense is used to indicate an ongoing action that started in the past and is still continuing in the present. It emphasizes the duration of the action.
- She has been reading that book all day.
- We have been living in New York for five years.
- He has been working on the project since morning.
Usage Rules for Present Perfect Tense
The Present Perfect Tense has specific situations and conditions when it can be correctly used.
Unspecified Point in the Past
As one of its primary uses, the present perfect tense is employed when the action happened at an unspecified time before now. The exact time is not critical, or perhaps not even known.
- I have seen that movie before.
You can use this tense to describe an experience up to the present time. It is important to note that you are not expected to state precisely when the experience occurred in the past.
- She has travelled all around the world.
Change Over Time
Present Perfect Tense is used to show a change or growth that has occurred over time.
- He has grown four inches this year.
Accomplishments
This tense is used to talk about achievements and milestones that have been completed recently/during the life of a person or thing.
- Scientists have split the atom.
Multiple Actions at Different Times
The Present Perfect Tense can also be used to refer to multiple actions which occurred at different times in the past.
- The artist has painted three pictures today.
Common Mistakes
Even though studying the rules above can help a lot, students often misuse the present perfect tense. The most common mistake is using the present perfect tense rather than the simple past when the time is specified.
Incorrect: I have seen him yesterday.
Instead, you should say – I saw him yesterday.
By learning and applying the basic rules of using the Present Perfect Tense, as detailed in this tutorial, you can significantly enhance your English communication skills. Remember to pay attention to the difference between the Present Perfect Simple and the Present Perfect Continuous tense. It's also essential to avoid common errors by referring to the examples given above. Over time, practice will ensure that you use this tense correctly and confidently.
