Answer:
1. dance 1. present
2. danced 2. past
3. will dance 3. future
4. have danced 4. present perfect
5. had danced 5. past perfect
6. will have danced 6. future perfect
Explanation:
A verb in the present maintains the infinitive form but without "to". For example: to walk --> walk
In the past, if the verb is regular, it gains -d, -ed, or -ied: walk --> walked
In the future, we use the auxiliary "will." Example: to walk --> will walk
The present perfect uses the auxiliary "have" and the main verb in the past participle: have walked
The past perfect uses the auxiliary "had" and the main verb in the past participle as well: had walked.
Finally, the future perfect uses both auxiliaries "will" and "have" plus the main verb in the past participle: will have walked.
