Concept Explanation

English questions usually place a helping verb before the subject. When be is the main verb, move it before the subject. For most other present-simple verbs, add do or does. Information questions place a question word before that question structure.

Negatives place not after be or after do/does. In conversation and informal writing, contractions such as isn't, aren't, don't, and doesn't are common. Short answers repeat the helping verb rather than the main verb.

  • Be: Is the report ready? The report is not ready.
  • Other verbs: Do you need help? I do not need help.
  • Information: Where does she work? Why are they waiting?
  • Short answers: Yes, I do. No, she isn't.

Examples & Patterns

The helping verb shows tense and agreement while the main verb stays in its base form after do or does.

Question and negative patternsEnglish
Statement:  You understand the requirement.
Question:   Do you understand the requirement?
Negative:   You do not understand the requirement.

Statement:  The deadline is flexible.
Question:   Is the deadline flexible?
Negative:   The deadline is not flexible.

Information question: Why does the customer need this change?
Be moves directly. Understand and need require do/does in simple-present questions and negatives.

Real-World Usage

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

  • Ask for requirements, deadlines, ownership, and clarification.
  • Confirm whether you understood a request correctly.
  • Correct an assumption without creating a confusing sentence.
  • Use open questions to invite more detailed answers.

Common Mistakes

Identify why each pattern is incorrect so you can transfer the correction to new sentences.

  • Keeping statement order: “Why she is late?”
  • Using do with be: “Does the report is ready?”
  • Keeping third-person -s after does: “Does he needs help?”
  • Answering a yes/no question with an unrelated verb form.

Practice Exercises

Write your answers, then read them aloud to strengthen both accuracy and fluency.

Activity 1

Build three forms

Turn five statements into yes/no questions and negatives. Include sentences with be and with ordinary present-simple verbs.

Hint: Decide first whether be is the main verb.

Activity 2

Ask useful follow-up questions

Imagine a colleague says, “The client wants a change soon.” Write five questions using what, why, when, who, and does.

Hint: Ask only for information that would help the work move forward.

Knowledge Check

Answer before revealing the explanation.

QUESTION 1

Which question is correct?

  1. A.Does she works remotely?
  2. B.Do she work remotely?
  3. C.Does she work remotely?
  4. D.Is she work remotely?
Reveal answer

Does she work remotely?

Does carries agreement, so work remains in the base form.

QUESTION 2

What is the correct question for “They are available”?

Reveal answer

Are they available?

When be is the main verb, move it before the subject.

Communication Practice

Apply the grammar to a realistic personal or professional message.

How would you politely clarify an unclear deadline?

Short answer: Ask a direct but courteous information question, such as “When do you need the final version?”

Explore the detailed answer

You can add context without weakening the question: “To help me prioritize the work, when do you need the final version?” The grammar stays direct, while the opening explains why you are asking.

Possible follow-ups

  • • How could you confirm the answer afterward?
  • • What is the yes/no version of the question?

Key Takeaways

Questions and negatives depend on the helping verb. Identify be or add do/does, keep the word order consistent, and use the form to seek genuinely useful information.

  • Questions usually place a helping verb before the subject.
  • Be forms its own questions and negatives.
  • Do/does supports most other present-simple verbs.
  • Question words come before the helping verb and subject.
