Past Tenses

Question Tags

Question tags are short questions added to the end of statements to ask for confirmation or agreement.

Structure: Auxiliary verb + pronoun

Common Question Tag Structures:

• For modal verbs: She will come, won't she?

Highlight: The auxiliary verb in the question tag is usually the opposite $positive/negative$ of the main clause.
