QUESTION GATE
Main shape:
[Wh-word?] + [gate-opener] + [subject] + [rest]?
↑
subject = the word doing the action or being described
Choose the gate-opener:
be → Are you ready?
another helper → Can you help me?
no helper → add do: Where do you live?
Wh-word goes before the opener:
What are you doing?
Who/What as the subject:
Who called you? ← Who is doing it: no did
Who did you call? ← you are doing it: use did
Use be or another helper as the opener; if there is none, add do. Wh-words go before it, except when who/what is the subject.
