โDid you receive the letter?โ and โHave you received the letter?โ are both possible questions, but they frame the event differently. Clear questioning begins with the information you want, followed by a verb form that suits the time and context.
Jobin Thomasโs Focused Grammar for OET Dentistry Writing includes question formation as well as sentence and note-expansion exercises. Its question chapter distinguishes routines, current situations, past events and experience up to now. This guide uses original administrative examples to practise those distinctions.
Decide what you need to find out
A question about a usual routine is different from a question about one particular day. โDo you usually work on Fridays?โ asks about a pattern. โDid you work last Friday?โ asks about a finished occasion. Choose the meaning before deciding which auxiliary to use.
You can also ask a more open question: โWhich days do you usually work?โ This invites information rather than a yes or no. The most useful form depends on what you already know and what remains unclear.
Use do, does and did with the base verb
For many present simple questions, use do or does + subject + base verb. Compare โThe clinic opens at nineโ with โDoes the clinic open at nine?โ The third-person ending belongs to โdoesโ in the question, so the main verb becomes โopen.โ
For a past simple question, use did + subject + base verb: โDid the clinic send the letter?โ Avoid โDid the clinic sent the letter?โ The auxiliary already marks the question as past.
Original transformation practice
Statement: The receptionist checks messages each morning.
Yes/no question: Does the receptionist check messages each morning?
Information question: When does the receptionist check messages?
Past occasion: Did the receptionist check the message yesterday?
Recognise questions that use a different auxiliary
With โbe,โ place the verb before the subject: โIs the appointment confirmed?โ A continuous form also uses โbeโ: โAre you waiting for a reply?โ A present perfect question uses โhaveโ or โhasโ: โHave you received a reply yet?โ
Do not add โdoโ to these patterns. โDo you are waiting?โ combines two question structures. Compare complete examples and notice which verb carries the question: โDo you wait here every week?โ versus โAre you waiting here now?โ
Correct these three questions
1. Does the clinic opens on Saturdays?
2. Did you received the message yesterday?
3. Have you wrote your reply yet?
Answers: โDoes the clinic open on Saturdays?โ โDid you receive the message yesterday?โ โHave you written your reply yet?โ The first two need a base verb after does/did; the third needs the past participle after have.
Keep duration separate from a starting point
โWhen did you start attending this class?โ asks for a starting time. โHow long have you attended this class?โ asks about duration up to now. A learner could answer the first with โIn Januaryโ and the second with โFor several months.โ
Both questions can be useful, but they are not interchangeable in every situation. Check that your wording invites the information you need. A grammatically correct question can still be unhelpful if it asks about the wrong period.
Build a small question-and-answer practice set
Choose an ordinary topic such as appointments, work or study. Write one question about a routine, one about a finished occasion and one about experience up to now. Answer each aloud, then ask whether the response matches the questionโs time frame.
What information am I asking for? Which time does it concern? Does my auxiliary match the main verb? Can the listener answer without guessing what I mean?
