To be Exercises with Answers (A1).
What Are Yes/No Questions with To Be?
We use yes/no questions with to be to ask about people and things and check if something is true. The answer to a yes/no question is always yes or no.
How We Use Yes/No Questions with To Be
- Identity: Is she a teacher?
- Description: Is this restaurant expensive?
- Nationality: Is he from Brazil?
- Age: Are you twenty years old?
- Location: Are they at the airport?
- Feelings and states: Is she happy today?
A yes/no question always starts with am, is, or are. The next panel shows exactly how to build one.
Question and Statement Pairs
Every yes/no question matches a statement with the same information.
| Statement | Question |
|---|---|
| Daniel is a nurse. | Is Daniel a nurse? |
| You are tired. | Are you tired? |
| The museum is open today. | Is the museum open today? |
How to Form Yes/No Questions with To Be
To make a yes/no question, move am, is, or are to the front of the sentence, before the subject.
Singular: I, You, He, She, It
| Statement | Question |
|---|---|
| I am late. | Am I late? |
| You are busy. | Are you busy? |
| He is a doctor. | Is he a doctor? |
| She is from Portugal. | Is she from Portugal? |
| It is expensive. | Is it expensive? |
Plural: We, You, They
| Statement | Question |
|---|---|
| We are late. | Are we late? |
| You are students. | Are you students? |
| They are teachers. | Are they teachers? |
Move am, is, or are before the subject. Do not add do or does. To be never uses do or does: ✗ Does she is happy? ✓ Is she happy?
Short Answers with To Be
We usually answer a yes/no question with a short answer, not a full sentence. A short answer has a subject plus am, is, or are.
Positive and Negative Short Answers
| Question | Yes | No |
|---|---|---|
| Am I late? | Yes, you are. | No, you aren't. |
| Are you ready? | Yes, I am. | No, I'm not. |
| Is he a teacher? | Yes, he is. | No, he isn't. |
| Are they at home? | Yes, they are. | No, they aren't. |
Positive short answers never contract: ✗ Yes, I'm. ✓ Yes, I am. Negative short answers can contract: No, he isn't. OR No, he's not.
More Examples
- Is this seat free? Yes, it is.
- Are your parents home? No, they aren't. They're at work.
- Am I right? Yes, you are.
Wh-Questions with To Be
A wh-question asks for information, not just yes or no. Start with a wh-word, then am, is, or are, then the subject.
Common Wh-Words with To Be
| Wh-word | Asks about | Example |
|---|---|---|
| What | a thing or an idea | What is your name? |
| Where | a place | Where are you from? |
| Who | a person | Who is that woman? |
| How | a state or condition | How is the weather today? |
| How old | age | How old are your children? |
| What time | time | What time is it? |
More Examples
- What is your favorite color?
- Where is the nearest bank?
- How old is your brother?
- Who are those students?
The word order stays the same as a yes/no question. Only the wh-word at the front changes: Is she a nurse? becomes What is she?
Common Mistakes with To Be Questions
Check your questions and short answers for these common mistakes.
Wrong Word Order
| Not correct | Correct | Tip |
|---|---|---|
| ✗ You are ready? | ✓ Are you ready? | Am, is, or are goes before the subject in a question, not after. |
| ✗ She is happy? | ✓ Is she happy? | A question mark alone does not make a question. Move is to the front too. |
Adding Do or Does
| Not correct | Correct | Tip |
|---|---|---|
| ✗ Does she is happy? | ✓ Is she happy? | To be never uses do or does. Just move am, is, or are. |
| ✗ Do you are ready? | ✓ Are you ready? | Do and does belong to other verbs, never to be. |
Short Answer Mistakes
| Not correct | Correct | Tip |
|---|---|---|
| ✗ Are you ready? Yes, I'm. | ✓ Are you ready? Yes, I am. | Positive short answers never contract. |
| ✗ Is he home? No, he not. | ✓ Is he home? No, he isn't. | A short answer still needs am, is, or are, even in the negative. |
Wrong Form in Wh-Questions
| Not correct | Correct | Tip |
|---|---|---|
| ✗ What are your name? | ✓ What is your name? | Your name is one thing (it), so use is, not are. |
| ✗ Where is your parents? | ✓ Where are your parents? | Your parents is plural (they), so use are, not is. |
