Tag questions are short questions added at the end of a statement to confirm information or seek agreement. The form of a tag question usually involves a pronoun, an auxiliary verb, and the opposite polarity of the main verb in the statement.
Let's analyze each sentence and choose the correct tag question:
They're speaking French, are they?
- Correct tag question: "are they" because the main verb "speaking" is in the present continuous form, so the auxiliary verb "are" should be used in the tag question.
Mia plays football, isn't he?
- Incorrect: "isn't he" should be changed to "doesn't she" because the subject is "Mia," so the correct tag question should use the auxiliary verb "does."
They won't be late, will they?
- Correct tag question: "will they" because the main verb "be" is in the negative future form using "won't," so the opposite polarity "will" should be present in the tag question.
You can speak Spanish, do you?
- Incorrect: "do you" should be changed to "can't you" because the main verb "speak" is in the modal "can speak," so the correct tag question should use the negative form "can't."
The artist painted a portrait of his friend, didn't he?
- Correct tag question: "didn't he" because the main verb "painted" is in the past tense, so the tag question should use the past auxiliary verb "did."
Jane never wants to be alone, does she?
- Correct tag question: "does she" because the main verb "wants" is in the present tense, so the auxiliary verb "does" should be in the tag question.
Therefore, the correct tag questions are:
- They're speaking French, are they?
- They won't be late, will they?
- The artist painted a portrait of his friend, didn't he?
- Jane never wants to be alone, does she?
