Transformation of Sentences

We can identify the types of sentences by analyzing them in terms of the following aspects:

For example:

  1. I would like to eat chocolate cake now. (Declarative sentence)
  2. Where can I get chocolate cakes? (Interrogative sentence)
  3. Please give me a chocolate cake. (Imperative sentence)
  4. How delicious the chocolate cake is! (Exclamatory sentence)

Type of Sentences

  1. When a speaker states or declares something, it is called a Declarative Sentence. (Statement)
  2. When a speaker asks a question, it is called an Interrogative Sentence. (Question)
  3. When a speaker orders, commands, or makes a request, it is called an Imperative Sentence. (Command/Order/Request)
  4. When a speaker expresses a strong feeling, it is called an Exclamatory Sentence. (Exclamation)

Ways of Transformation of a Sentence

1. First, let us discuss how to change a declarative sentence into an interrogative sentence.

A. As shown in the example, we change a declarative sentence into an interrogative sentence by putting the auxiliary verb before the


  • He is a chemist. (Declarative)

Is he a chemist? (Interrogative)

  •  We are going to the park. (Declarative)

Are we going to the park? (Interrogative)

It can be seen from the above transformation that a period is used for declarative sentences, and an interrogative sentence ends with a question mark?

B. When the declarative sentence is in the simple present tense, we use to do or does to make questions.


  • Mathews lives here. (Declarative)

Does Mathews live here? (Interrogative)

  • They love singing. (Declarative)

Do they love singing? (Interrogative)

C. In the simple past tense, we make questions with did.

  • Anne came in the morning. (Declarative)

         Did Anne come in the morning? (Interrogative)s

  • Michael saw her yesterday. (Declarative)

         Did Michael see her yesterday? (Interrogative)

2. To change an imperative to a declarative sentence, use proposed, suggested, ordered, etc.


  • He said, “Let us go out for a walk.”

Indirect: He suggested going out for a walk.

  •  The captain said to the soldiers, “Fire at the enemy.”

Indirect: The captain ordered the soldiers to fire at the enemy.

3. Transformation of an exclamatory sentence into a declarative sentence.

This transformation of a sentence should happen without altering its sense.


  • What a wonderful twist to the story! (Exclamatory)

It is a very wonderful twist to the story. (Assertive)

  • How kind of Jude to help John like that! (Exclamatory)

It is very kind of Jude to help John like that. (Assertive)

4. Changing an imperative sentence into an interrogative sentence.

Add the helping verb/modal verb before the pronoun and noun to make it interrogative.

  • Shut the door. (Imperative)

Will you shut the door? (Interrogative)

  • Please, get me a cup of tea. (Imperative)

Will you please, get me a cup of tea? (Interrogative)

Note: The interrogative is a milder or more polite form of the imperative.
