What is the Past Simple Tense?

The Past Simple tense describes actions that started and finished in the past. It tells us about events that are now complete.

For example, I visited Paris last year. または They ate dinner at 7 PM.

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

To ask a question that can be answered with ‘yes’ or ‘no’, we use a simple structure.

• Start with Did.
• Then add the subject (I, you, he, she, it, we, they).
• Finally, use the base form of the main verb (the infinitive without ‘to’).

The structure is: Did + Subject + Base Form of Verb + …?

How Do We Form Wh- Questions in the Past Simple?

‘Wh-‘ questions ask for specific information. They start with words like what, where, when, why, who, 、または how.

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

The structure is: Wh- word + did + Subject + Base Form of Verb + …?

There is one important exception: When who is the subject of the question, we do not use did. We use the Past Simple form of the main verb directly.

Why Does the Main Verb Stay in the Base Form?

This is a key point to remember! In Past Simple questions, the auxiliary verb did already shows that the question is about the past.

Because did carries the past tense information, the main verb does not need to change its form. It always stays in its base (infinitive) form.

Examples

• Did you enjoy the movie?
• Did she finish her work yesterday?
• Did they travel to Spain last summer?
• What did you eat for lunch?
• Where did he go after class?
• When did they arrive home?
• Why did you call me?
• How did you learn English?
• Who called you? (Here, ‘who’ is the subject)
• Who did you call? (Here, ‘who’ is the object)

Common mistakes for Spanish speakers

Common Mistakes for Spanish Speakers

In Spanish, you often change the main verb to form a past question. In English, it’s different. A common mistake is to use the past tense form of the main verb after did.

• Did you went to the park? (Incorrect)
• Did you go to the park? (Correct)

Another error is to forget did completely, especially in ‘wh-‘ questions.

• What you did yesterday? (Incorrect)
• What did you do yesterday? (Correct)

Also, remember that did is for action verbs. Do not use did with the verb to be.

• Did you be happy? (Incorrect)
• Were you happy? (Correct)

よくある質問

What is the main difference between ‘Did you go…?’ and ‘Were you…?’

We use Did you go…? for action verbs, like ‘go’, ‘eat’, ‘study’. We use Were you…? for the verb to be, to ask about states or conditions, for example, Were you tired? または Were you at home?

Can I use ‘did’ with the verb ‘to be’?

No, you cannot use did with the verb to be in the Past Simple. For questions with to be, you simply put was または were before the subject, like Was he busy? または Were they ready?

Do I always use ‘did’ for Past Simple questions?

You use did for almost all Past Simple questions, except for two cases: when the main verb is to be (use was/were instead) or when who is the subject of the question (e.g., Who broke the window?).
