Tenses: English Language Notes for Andaman & Nicobar Islands TET (Teacher Eligibility)

English Language – Tenses

Andaman & Nicobar Islands TET – Teacher Eligibility Test
(For candidates preparing to teach English)

1. Simple Explanation

Tenses are grammatical tools that place an action in time.
English has three main tenses (Present, Past, Future) and four aspects that can combine with each tense:

Aspect	Example	Meaning
Simple	She writes.	Habitual or general truth.
Continuing (Progressive)	She is writing.	Action in progress at a specific moment.
Perfect	She has written.	Action completed before another time.
Perfect‑Continuing	She has been writing.	Action started in the past, still continuing.

By merging any tense with an aspect we get 12 primary verb forms (e.g., present perfect continuous).

2. Key Points

Category	Key Points
Present Tenses	• Simple Present – habits, facts (e.g., They eat* breakfast.) • Present Continuous* – ongoing action now (e.g., They are eating.) • Present Perfect – action finished at an unspecified time (e.g., They have eaten.) • Present Perfect Continuous – action started earlier, still continuing (e.g., They have been eating* for 20 min.*)
Past Tenses	• Simple Past – completed action at a definite time (e.g., They ate* yesterday.) • Past Continuous* – action in progress at a past time (e.g., They were eating* when I arrived.) • Past Perfect* – action finished before another past action (e.g., They had eaten* before the party.) • Past Perfect Continuous* – action started before a past event and continued up to that event (e.g., They had been eating* for 30 min when the rain started.*)
Future Tenses	• Simple Future – intention or prediction (e.g., They will eat* soon.) • Future Continuous* – action in progress at a future time (e.g., They will be eating* at 7 pm.) • Future Perfect* – action completed before a future time (e.g., They will have eaten* by 8 pm.) • Future Perfect Continuous* – action that will continue up to a future point (e.g., They will have been eating* for 45 min by 8 pm.*)
Common Usage Rules	• Use simple present for general truths or routines. • Use present continuous for actions happening right now. • Use present perfect to connect past actions to present. • Use past continuous to set background in a narrative. • Use past perfect to show earlier of two past events. • Use future simple for spontaneous decisions; future continuous for scheduled events.
Negative & Interrogative Forms	• Negatives: add not after auxiliary (e.g., She is not* writing.). • Interrogatives: invert subject & auxiliary (e.g., Are they writing?*).
Common Mistakes	• Mixing have with has (he/she/it → has). • Forgetting auxiliary in continuous/perfect forms. • Using simple past where present perfect is needed (e.g., I finished the book → I have finished the book).

3. Worked Example

Sentence: “When I arrived at the school, the students were already writing their essays, and the teacher had been explaining the assignment for 20 minutes.”

Breakdown

Clause	Tense & Aspect	What it tells us
When I arrived at the school	Simple Past	The arrival happened at a specific past moment.
the students were already writing	Past Continuous	The action of writing was ongoing at that past moment.
the teacher had been explaining	Past Perfect Continuous	The teacher started explaining earlier and continued up to that moment.
for 20 minutes	Time adverbial	Specifies duration of the continuous action.

Why this tense mix?

The past continuous shows what the students were doing at a particular past time.
The past perfect continuous indicates that the teacher’s explanation began before that same past time and was still happening.
The simple past marks the arrival, the anchor point for the narrative.
