Talking about something happened in the past time can not be avoided from daily speaking, specially in English Language. All non native speakers should understand enough about the structure of it.
Someone who speaks with his or her own language, sometimes, doesn't realize that he or she speaks with some structures. Structure of A sentence which describes past event will be related to the past form or pattern. This rule should be learned by all English learners when he or she wants to express something happened in the past time.
There are two types of patterns in Expressing Past Event:
1. Nominal Pattern
2. Verbal Pattern
In Nominal Pattern, we should use Be-past (Was or Were) and place non verbs after it.
------- + Non-Verb
Note that We use /Was/ when the subject is I, She, He or It and We use /Were/ when the subject is We, They and You.
I was ill yesterday.
Take notice that the word /ill/ is an adjective (we also say it : Predicate), not Verb.
In Verbal Form, we don't face to non verb, but Verb. Here, we use the second form of verb. To find it easily, you can find it in Regular and Irregular Verb Lists/Tables.
So, place the verb after the subject. For example:
Subject + Verb-2
She talked to me for hours.
The verb /Talked/ describes something happened /talked/ in the past time. Although we don't insert an adverb of time, by looking at the verb type (V-2) we, automatically, know that the pattern is in Verbal Form of Simple Past Tense.
The sentence will be more informative when An adverb of time is enclosed.
She Talked to me for hours yesterday
