Question Tags Questions
The rules for using question tags in positive statements are as follows:
1. If the main verb in the positive statement is in the present tense, the question tag is formed by using the auxiliary verb "do" or "does" in the opposite form.
Example: He likes coffee, doesn't he?
2. If the main verb in the positive statement is in the past tense, the question tag is formed by using the auxiliary verb "did" in the opposite form.
Example: They went to the party, didn't they?
3. If the main verb in the positive statement is in the present perfect tense, the question tag is formed by using the auxiliary verb "have" or "has" in the opposite form.
Example: She has finished her homework, hasn't she?
4. If the main verb in the positive statement is a modal verb, the same modal verb is used in the question tag.
Example: You can swim, can't you?
5. If the main verb in the positive statement is "let's", the question tag is formed by using "shall we".
Example: Let's go to the park, shall we?
