1) The document explains different tenses in English grammar, specifically focusing on past tenses. It uses visual graphics like timelines to illustrate the differences between simple past, past progressive, and past perfect tenses.
2) Simple past tense refers to single occurrences in the past, while past progressive describes actions that were ongoing over a period of time in the past.
3) Past perfect tense is used to show that one past action had already occurred when another past action took place. It indicates the earlier action happened before the later action in the past.
2. In grammar, TENSE is regarded by many as the most
challenging topic for a teacher to teach and the most
difficult lesson for a student to learn.
We have tried to explain tense using
visual graphics to make the chapter on tense
easier to explain and comprehend.
Part_2 deals with Past Indefinite, Progressive, and Per
Tense forms.
3. Past Present Future
Timeline
The above rectangular bar represents the timeline with the various color
shades representing the past, the present and the future.
We have chosen a gradient rather than three distinct solid colors because
the terms past, present, etc. are relative and context-dependent. In some
contexts, today’s happenings are to be expressed in the present tense; in
some other contexts, what happened this morning or even what
happened a few minutes ago may be reported in the past tense. Similarly,
what is going to happen in the future is always uncertain.

1. I was born on 13th June 2000.
2. He came to the city five years ago.
3. We went to London last year.
4. I just finished my homework.
Each of the statement is
represented as a single point of
time on the timeline.
All are in the past and they do not
extend across the timeline to any
lengths either way.
5. Past Indefinite or Simple Past Tense
Recall that sentences in simple present tense should be represented by
multiple points and stretch both ways along the timeline from the
present. They are general truths.
By contrast, sentences in simple past tense refer to a single occurrence
of an event / one-time fact and are represented by a single point in the
past only.
The idea is further reinforced in the next three graphics.

9. Past Indefinite or Simple Past Tense
[caveat]
A sentence like I played cricket yesterday refers to a one-time fact or a
single event / occurrence; however, it does not imply that I have never
played cricket before or that I will never play cricket again. All it
implies is that the sentence is about the one game I played yesterday,
and the games I might have played earlier or will play in the future is
not covered within the scope of this particular sentence.

14. Past Perfect Tense
In most cases, a past perfect (had + a participle-form verb, like had arrived) is used
with a simple past to indicate that one action had preceded the other.
In other words, a past perfect verb shows that the action was already completed at a
point of time when the second action took place in the past.
If one action X had taken place 5 hours ago, and another action Y took place 3 hours
ago, we write the earlier (more remote past) action X in the past perfect and the other
action Y in the simple past.
