English grammar becomes much easier when you understand how sentences work.

Three important grammar topics that help you write better sentences are:

  • Active and Passive Voice
  • Direct and Indirect Speech
  • Subject-Verb Agreement

These topics may look difficult at first, but they are built on simple ideas. Active and passive voice help us understand who is doing an action. Direct and indirect speech help us report what someone said. Subject-verb agreement helps us make sure the subject and verb match correctly.

In this lesson, we will learn all three topics with clear explanations and easy examples.

Part 1: Active and Passive Voice

Voice tells us whether the subject of a sentence is doing the action or receiving the action.

There are two main voices in English:

  • Active voice
  • Passive voice

What Is Active Voice?

In active voice, the subject does the action.

Formula

Subject + Verb + Object

Example

"The boy kicked the ball."

Subject:

  • The boy

Verb:

  • kicked

Object:

  • the ball

The boy is doing the action, so this sentence is in active voice.

More Examples of Active Voice

  • The teacher explained the lesson.
  • Sarah wrote a letter.
  • The dog chased the cat.
  • My mother cooked dinner.
  • The students completed the project.

In each sentence, the subject performs the action.

What Is Passive Voice?

In passive voice, the subject receives the action.

Formula

Object + be verb + past participle + by + subject

Example

"The ball was kicked by the boy."

Here, the ball receives the action. The boy performs the action, but the sentence focuses on the ball.

More Examples of Passive Voice

  • The lesson was explained by the teacher.
  • A letter was written by Sarah.
  • The cat was chased by the dog.
  • Dinner was cooked by my mother.
  • The project was completed by the students.

Active Voice vs Passive Voice

Active VoicePassive Voice
The boy kicked the ball.The ball was kicked by the boy.
Sarah wrote a letter.A letter was written by Sarah.
The dog chased the cat.The cat was chased by the dog.
The teacher explained the lesson.The lesson was explained by the teacher.

When Should You Use Active Voice?

Use active voice when you want your sentence to be clear, direct, and strong.

Example:

"The manager approved the plan."

This sentence is simple and direct.

When Should You Use Passive Voice?

Use passive voice when the action is more important than the person doing it.

Example:

"The window was broken."

Here, we may not know who broke the window, or the broken window may be more important than the person.

Passive voice is also common in formal writing, news reports, and scientific writing.

Examples:

  • The results were recorded.
  • The building was completed in 2020.
  • The documents were signed yesterday.

How to Change Active Voice to Passive Voice

Step 1

Find the object of the active sentence.

Active:

"The chef prepared the meal."

Object:

  • the meal

Step 2

Move the object to the beginning.

"The meal..."

Step 3

Add the correct form of the verb "to be."

"The meal was..."

Step 4

Add the past participle.

"The meal was prepared..."

Step 5

Add "by" and the doer if needed.

"The meal was prepared by the chef."

Part 2: Direct and Indirect Speech

Speech is used when we talk about what someone said.

There are two main ways to report speech:

  • Direct speech
  • Indirect speech

What Is Direct Speech?

Direct speech repeats the exact words spoken by someone.

It usually uses quotation marks.

Example

Sarah said, "I am happy."

The words inside the quotation marks are Sarah's exact words.

More Examples of Direct Speech

  • John said, "I like football."
  • The teacher said, "Open your books."
  • She said, "I am going home."
  • He asked, "Where are you going?"
  • Mother said, "Dinner is ready."

What Is Indirect Speech?

Indirect speech reports what someone said without using the exact words.

Quotation marks are not used.

Example

Direct speech:

Sarah said, "I am happy."

Indirect speech:

Sarah said that she was happy.

The meaning is the same, but the words are reported differently.

Direct Speech vs Indirect Speech

Direct SpeechIndirect Speech
He said, "I am tired."He said that he was tired.
She said, "I like music."She said that she liked music.
John said, "I will come tomorrow."John said that he would come the next day.
They said, "We are ready."They said that they were ready.

Common Changes in Indirect Speech

When changing direct speech to indirect speech, some words often change.

Pronoun Changes

Direct:

He said, "I am busy."

Indirect:

He said that he was busy.

The pronoun "I" changes to "he."

Tense Changes

Direct:

She said, "I am tired."

Indirect:

She said that she was tired.

"Am" changes to "was."

Time Word Changes

Some time words also change.

Direct SpeechIndirect Speech
nowthen
todaythat day
tomorrowthe next day
yesterdaythe previous day
herethere
thisthat

Examples of Direct to Indirect Speech

Statement

Direct:

He said, "I love English."

Indirect:

He said that he loved English.

Question

Direct:

She asked, "Are you ready?"

Indirect:

She asked if I was ready.

Command

Direct:

The teacher said, "Close the door."

Indirect:

The teacher told me to close the door.

Request

Direct:

He said, "Please help me."

Indirect:

He requested me to help him.

Part 3: Subject-Verb Agreement

Subject-verb agreement means the subject and verb in a sentence must match.

If the subject is singular, the verb should usually be singular.

If the subject is plural, the verb should usually be plural.

What Is a Subject?

The subject is who or what the sentence is about.

Examples:

  • The boy runs.
  • The girls sing.
  • My friend plays cricket.

Subjects:

  • The boy
  • The girls
  • My friend

What Is a Verb?

The verb tells us what the subject does or is.

Examples:

  • runs
  • sing
  • plays

Basic Subject-Verb Agreement Rule

Singular Subject + Singular Verb

Example:

"The boy runs."

Plural Subject + Plural Verb

Example:

"The boys run."

Notice the difference:

  • boy runs
  • boys run

In the present simple tense, singular subjects often take verbs ending in -s or -es.

More Examples

SingularPlural
She writes.They write.
He plays.They play.
The dog barks.The dogs bark.
The teacher explains.The teachers explain.

Subject-Verb Agreement with "Is" and "Are"

Use "is" with singular subjects.

Examples:

  • The child is happy.
  • My sister is at home.
  • The book is on the table.

Use "are" with plural subjects.

Examples:

  • The children are happy.
  • My sisters are at home.
  • The books are on the table.

Subject-Verb Agreement with "Has" and "Have"

Use "has" with singular subjects.

Examples:

  • She has a pencil.
  • The boy has a bicycle.

Use "have" with plural subjects and "I" and "you."

Examples:

  • They have pencils.
  • We have books.
  • I have a question.
  • You have a nice bag.

Common Subject-Verb Agreement Mistakes

Mistake 1

Incorrect:

"She go to school."

Correct:

"She goes to school."

Mistake 2

Incorrect:

"They is ready."

Correct:

"They are ready."

Mistake 3

Incorrect:

"The dogs barks loudly."

Correct:

"The dogs bark loudly."

Mistake 4

Incorrect:

"He have a car."

Correct:

"He has a car."

Subject-Verb Agreement with Compound Subjects

When two subjects are joined by "and," the verb is usually plural.

Example:

"John and Mary are friends."

More examples:

  • Tea and coffee are available.
  • My brother and sister play tennis.
  • The teacher and the students are in the classroom.

Subject-Verb Agreement with "Or"

When subjects are joined by "or," the verb usually agrees with the subject closest to it.

Examples:

  • Either John or his friends are coming.
  • Either the friends or John is coming.

The nearest subject decides the verb.

Summary

Active and passive voice, direct and indirect speech, and subject-verb agreement are important parts of English grammar.

Active voice shows that the subject does the action.

Example:

Passive voice shows that the subject receives the action.

Example:

"The ball was kicked by the boy."

Direct speech reports exact words.

Example:

She said, "I am happy."

Indirect speech reports the meaning without exact words.

Example:

She said that she was happy.

Subject-verb agreement means the subject and verb must match.

  • They walk.

Once you understand these three grammar topics, your English sentences become clearer, stronger, and more accurate.
