Subject Questions
Question words ask about the object of a statement:
| statement | I work in London. |
| question | Where do I work? |
| answer | In London. |
But we can also ask about the subject. To do this we replace the subject with a question word:
| statement | {subject} + {verb} ...
|
| question | {question word} + {verb} ...
|
| statement | Winter is coming.
|
| question | What is coming?
|
| answer | Winter is.
|
| statement | John's father has joined the army.
|
| question | Whose father has joined the army?
|
| answer | John's father.
|
Note: we cannot use when or where to ask questions about the subject.
