Grammar Chapter 3: Time and Tense

📖 Grammar Chapter 3 — Time and Tense: The longest and most important chapter of the book. It clears the difference between time (real) and tense (a verb form), shows the three forms of a verb, and then explains every present and past tense and all the ways English expresses the future. Learn this well and the whole of English grammar becomes easy.

A. Time vs Tense

Time flows continuously and is divided into three periods: the past (before now), the present (now) and the future (after now).

Note: a verb may be in the present tense but refer to future or past time. e.g. “Tina will arrive soon.” — the tense is present, the time is future.

B. The Three Forms of a Verb

The third form (–ed / –en) is needed to make the present perfect, the past perfect and the passive.

C. Tense & Aspect — 8 combinations

Each of the two tenses can combine with an aspect: simple (neither perfect nor progressive), perfect, progressive, or perfect progressive. 2 tenses × 4 aspects = 8 verb forms, used to speak of all three times.

D. The Present Tenses

1. Present Simple

Used for: habits (with always, often, usually, sometimes, never); general / scientific truths (The sun rises in the east); a permanent state or fact (Bhubaneswar is the capital of Odisha); running commentaries; formal declarations (I apologise…); a fixed-timetable future (The train arrives at 9 a.m.); and in ‘if’ clauses (If we heat iron, it expands).

2. Present Progressive (be + -ing)

Used for an action going on now (It is raining now); a brief action around now (Sabita is getting into the bus); a temporary action (He is going by bicycle today); a changing condition (Prices are going up); and with always / for ever / constantly for an annoying, repeated action (He is always losing his keys).

3. Present Perfect (have / has + -en)

Used for a past action with a present result/relevance (I have polished my shoes — they shine now). The focus is on the present result, not the time.

• for = a period of time; since = the point when the action began. (We have lived here for five years / since 2005.)
• been to = visited (and returned); been in = stayed. (Rakesh has been to Kanyakumari.)
• Adverbs: just, ever, never, lately, recently, already, yet, often. Use already in affirmatives and yet in negatives/questions.

4. Present Perfect Progressive (have / has been + -ing)

Shows an activity that started in the past, continues till now and may extend into the future, or a very recent activity whose result is visible (His hands are dirty — he has been working in the garden).

E. The Past Tenses

1. Past Simple (V2)

An action that began and ended in the past (India became free in 1947), or a past habit. used to works for past actions and states; would only for past actions (He used to / would visit us every Sunday; but only “used to” for the state “used to be ill”).

2. Past Progressive (was / were + -ing)

An action in progress in the past (I was taking breakfast at 8 a.m.), often the background when another, shorter action happened (When I was reading, somebody knocked — knocked is past simple).

3. Past Perfect (had + -en)

When two actions happened in the past, the earlier one takes the past perfect and the later one the past simple. (When we reached the station, the train had left.) If both happen at the same time, use past simple in both parts.

4. Past Perfect Progressive (had been + -ing)

A past action that was in progress when another event took place. (They had been driving for two hours when the car broke down.)
