How Do We Ask Yes/No Questions in the Past Simple?

When you want a ‘yes’ or ‘no’ answer about a past action, you start your question with Did.

• Use Did for all subjects: I, you, he, she, it, we, they.
• After Did and the subject, always use the base form of the main verb. This is the verb without -ed or any other change.

The pattern is: Did + subject + base form of verb + …?

How Do We Ask for Information (Wh- Questions)?

If you want more specific information (like ‘what,’ ‘where,’ ‘when,’ ‘who,’ ‘why,’ or ‘how’), you put a Wh- word at the beginning.

• Start with the Wh- word.
• Then, add did.
• Next, put the subject.
• Finally, use the base form of the main verb.

The pattern is: Wh- word + did + subject + base form of verb + …?

What About the Verb ‘To Be’ in the Past?

The verb to be is special. We do not use did with was または were.

• For questions with to be, simply put was または were before the subject.
• Use was for I, he, she, it.
• Use were for you, we, they.

The patterns are: Was/Were + subject + …? または Wh- word + was/were + subject + …?

Examples

• Did you watch TV last night?
• Did they finish their homework?
• Where did she go yesterday?
• What did he eat for breakfast?
• When did you arrive?
• How did you get here?
• Was she happy?
• Were they at the party?
• Why was he late?

Common mistakes for Spanish speakers

Common Mistakes for Spanish Speakers

Spanish speakers sometimes make these mistakes when forming past simple questions:

• Using the past form of the main verb after did:
  Incorrect: Did you went to the park?
  Correct: Did you go to the park?
  Remember, did already shows the past, so the main verb stays in its base form.
• Not using did for most verbs:
  Incorrect: You watched TV last night? (This sounds like a statement, not a question.)
  Correct: Did you watch TV last night?
  In English, we need did to form questions about past actions (except for to be).
• Using did with the verb to be:
  Incorrect: Did you were happy?
  Correct: Were you happy?
  The verb to be (was/were) does not need did to form questions.

よくある質問

When do I use ‘did’ in a question?

You use did to ask about most actions that happened and finished in the past. For example, Did you eat lunch?

Do I change the verb after ‘did’?

No, after did, you always use the base form of the main verb. For example, Did he play? (not played).

Can I use ‘did’ with ‘was’ or ‘were’?

No, never. Was そして were are already past forms of to be. You ask directly: Was she here? または Were they busy?

What is the difference between ‘Did you go?’ and ‘Where did you go?’

Did you go? is a Yes/No question, asking if the action happened. Where did you go? is a Wh- question, asking for specific information about the place.
