Explanation:
- Simple tenses consist of a main verb conjugated to express the time the action takes place - present, past, or future. In the case of the simple future, the main verb will have the help of auxiliary verbs even in the affirmative form. For example: work - worked - will work.
- Perfect tenses need to use the auxiliary "have" to convey their meaning. "Have" will be the one indicating when the action takes place. The main verb is used in the past participle form. For example: have/has done / had done / will have done
- Progressive tenses indicate that the action lasts for a period of time. They need the auxiliary "be", and the main verb is used in the present participle form. Example: is running / was running / will be running
- Finally, it is possible to have tenses that are both perfect and progressive. In this case, we need both the auxiliaries "have" and "be". "Be" is employed in the past participle form. The main verb is used in the present participle form. Example: have/has been cooking / had been cooking / will have been cooking
