5. Imperative Mood
The form of the verb that makes direct commands and requests.
There are three major moods in English: the indicative mood is used to make factual statements or pose questions, the imperative mood to express a request or command, and the (rarely used) subjunctive mood to show a wish, doubt, or anything else contrary to fact.

6. Example
"Read, every day, something no one else is reading. Think, every day, something no one else is thinking. Do, every day, something no one else would be silly enough to do. It is bad for the mind to be always part of unanimity." (Christopher Morley)
"Just do it." (Nike advertising slogan)

The simple past tense is sometimes called the preterite tense. We can use several tenses to talk about the past, but the simple past tense is the one we use most often.

we use: past form only or auxiliary did + base form
The structure for positive sentences in the simple past tense is: subject + main verb past form
The structure for negative sentences is:
subject + auxiliary verb( did) + not + main verb (base form)
The structure for question sentences is:

We use the simple past tense to talk about an action or a situation - an event - in the past. The event can be short or long.
We use the simple past tense when:
the event is in the past
the event is completely finished
we say (or understand) the time and/or place of the event
