When we want to ask yes/no questions we can use do/does, am/is/are or have/has as question words. We use do or have or am with personal pronouns (I), we use does or has or is with third person singular pronouns (he, she, it) and with singular noun forms. We use do or have or are with other personal pronouns (you, we they) and with plural noun forms.

Yes/no questions with the verb be are created by moving the verb be to the beginning of the sentence. In other words the subject and the verb change their positions in statements and questions.
Statement:
I am from England.
Question: Am I from England?
When forming questions in the present continuous tense use the verb be. I am speaking English. = Am I speaking English?

You are speaking English. = Are you speaking English?

He is speaking English. = Is he speaking English?

She is speaking English. = Is she speaking English?

It is speaking English. = Is it speaking English?

We are speaking English. = Are we speaking English?

They are speaking English. = Are they speaking English?

When forming questions in the present simple tense use the verb be, do, or have. The auxiliary verb is placed before the subject. To Be If there is one verb in the statement and the verb is a form of be , simply switch the positions of the subject and verb. I am English. = Am I English?

You are English. = Are you English?

He is English. = Is he English?

She is English. = Is she English?

It is English. = Is it English?

We are English. = Are we English?

They are English. = Are they English?

To Do If there is one verb in the statement and the verb is do, simply switch the positions of the subject and verb. I do. = Do I? You do. = Do you?

He does. = Does he?

She does. = Does she?

It does. = Does it?

We do. = Do we?

They do. = Do they?

To Have If there is one verb in the statement and the verb is have, (with or without got to show possession), switch the positions of the subject and verb. I have (got) an English book. = Have I (got) an English book?

You have (got) an English book = Have you (got) an English book?

He has (got) an English book = Has he (got) an English book?

She has (got) an English book = Has she (got) an English book?

It has (got) an English book = Has it (got) an English book?

We have (got) an English book = Have we (got) an English book?

They have (got) an English book = Have they (got) an English book?

We can also form this style of question with Do�have�? here there is no subject-verb inversion, do is placed before the subject. I have breakfast every morning. = Do I have breakfast every morning?

You have breakfast every morning. = Do you have breakfast every morning?

He has breakfast every morning. = Does he have breakfast every morning?

She has breakfast every morning. = Does she have breakfast every morning?

It has breakfast every morning. = Does it have breakfast every morning?

We have breakfast every morning. = Do we have breakfast every morning?

They have breakfast every morning. = Do they have breakfast every morning?

If there is one verb, and the verb is not a form of be, the process is more complex. To form a question add the correct form of the verb 'to do' to the beginning. Here there is no subject verb inversion. I speak English. = Do I speak English?

You speak English. = Do you speak English?

He speaks English. = Does he speak English?

She speaks English. = Does she speak English?

It speaks English. = Does it speak English?

We speak English. = Do we speak English?

They speak English. = Do they speak English?

Answering a Closed Question

For example: "Are you from England?"

You can answer closed questions with "Yes" or "No".

You can also answer closed questions with a slightly longer answer "Yes, I am." or "No, I'm not."

Finally you can answer closed questions in the long form "Yes, I am from England." or "No, I'm not from England."
