Questions Interrogative sentences

Hello dear english learners
Welcome to this course where we will talk about questions in the english language.
The main change to do when we pass from affirmative sentence to an interrogative sentence (question) is to invert the order of the subject and the first auxiliary verb. Here are some examples:

You are from France. Are you from France?
Marc is a teacher. Is Marc a teacher?
I read a book. Do you read a book?
He read a book. Does he read a book?
I went to school. Did you went to school?

From these example we can deduce these rules:

  • When the verb is ‘to be’ we just invert the subject and the verb (Example 1 & Example 2)
  • When it’s another verb we add to the sentence the verb ”To do’ in the same tense of the verb of the affirmative sentence. (Simple present in Example 3 & Example 4, and simple past in example 5).

For the tense ‘simple past and simple present’ interrogative sentences have the fome:

To do + the affirmative sentence

For the perfect tenses we use the form: Have+subject+participle of the verb. Examples:

I have been at school Have you been at school?

it’s like the first examples (example 1 & example 2), because we  invert the order of the subject and the first auxiliary verb.

Same thing for some different expressions like modal verbs and the adverbs: we  invert the order of the subject and the modal verb or the adverb. Examples:

I am at home. Where are you?
Yes, I can read this book. Can you read this book?
I read a book. What do you do?
