Subject Questions

• Normally, questions need 'do' or 'did'. But when we ask about the subject who does the action, we do not use 'do' or 'did'. We use 'Who' or 'What' directly with the verb.
• Question word
• Verb (Past simple)
• Rest of sentence
• Who
• changed
• the logo in Seattle?
• What
• happened
• in Austin yesterday?
• Who
• deleted
• the component in Boston?
• Remember
• Use subject questions when you want to know the person or thing that does the action.
• Do not use auxiliary verbs like 'did' in subject questions.
• The verb after 'Who' or 'What' is usually in the past simple or present simple.
• The word order is the same as a normal affirmative sentence: Subject + Verb + Object.
• Examples
• Who broke the button in Chicago?
• What happened to the shared library in Denver?
• Who noticed the mistake in San Francisco?
• Common mistakes
• Who did break the design?
• Who broke the design?
• What did happen in the studio?
