Concept Explanation

Be, have, and do appear constantly in English. Each can act as a main verb, and each can also help form larger verb structures. Mastering them makes questions, negatives, descriptions, and everyday workplace sentences much easier.

The verb be changes to am, is, and are in the present. Have changes to has with he, she, and it. Do changes to does with he, she, and it when it helps form present-simple questions and negatives.

Be: I am ready. She is ready. They are ready.
Have: I have a question. He has a question.
Do as a main verb: We do the work.
Do as a helper: Do you work here? She does not work here.

Examples & Patterns

Compare statements, negatives, and questions. Be changes position directly; other present-simple verbs usually need do or does.

Core verb patternsEnglish

I am available.        I am not available.        Are you available?
She has experience.    She does not have time.    Does she have time?
They work remotely.    They do not work Friday.   Do they work Friday?

Notice that does carries the third-person change, so the main verb returns to its base form: have, not has.

Real-World Usage

Connect the grammar to communication you can use outside a textbook.

Describe your role, location, availability, and current condition.
Ask for information politely and accurately.
Explain what resources or experience someone has.
Form clear negatives when correcting an assumption.

Common Mistakes

Notice the pattern behind each mistake so you can correct similar sentences yourself.

Using be with another base verb: “I am work here.”
Forgetting do in a present-simple question: “You work here?” in formal contexts.
Using has after does: “Does she has experience?”
Using the wrong form of be: “They is ready.”

Practice Exercises

Say your answers aloud as well as writing them. Speaking and writing reinforce different parts of the skill.

Activity 1

Transform the sentence

Change “He works remotely” into a negative and a question. Then do the same with “He is remote today.”

Hint: One sentence needs does; the other changes the position of is.

Activity 2

Create a short work profile

Write six sentences about a fictional professional using be, have, and do at least once each.

Hint: Include one question and one negative sentence.

Knowledge Check

Answer before revealing the explanation.

QUESTION 1

Which question is correct?

A.Does she has a laptop?
B.Does she have a laptop?
C.Is she have a laptop?
D.Do she has a laptop?

Reveal answer

Does she have a laptop?

Does marks third-person singular, so have stays in its base form.

QUESTION 2

Why does “Are they ready?” not use do?

Reveal answer

The verb be forms its own questions by moving before the subject.

Do is not added when be is the main verb in a simple present question.

Learning stage

Communication Practice

Use the grammar to express a complete idea in a realistic personal or professional situation.

How would you ask whether a colleague is available and has the required document?

Short answer: Ask two clear questions: “Are you available?” and “Do you have the document?”

Explore the detailed answer

The first question uses be, so are moves before the subject. The second uses have as a main verb in present simple, so do appears before the subject. Separating the questions also makes the request easier to answer.

Possible follow-ups

• How would you make both questions more polite?
• How would the forms change with she?
