Reading Resources: English Grammar 4 – Tenses & Modals

This blog is part of the English Grammar Reading Resources series for students and learners. The blog series covers essential English grammar concepts in a simple, structured, and practical way. Each reading resource introduces key grammar rules, explains their usage with clear examples, and provides practice activities to help learners improve their grammatical accuracy and confidence.

In this fourth reading, “Tenses & Modals,” learners will understand how English grammar expresses time, actions, events, possibility, ability, permission, obligation, advice, and necessity. The reading introduces the major tense forms and commonly used modal verbs through clear explanations, examples, and practical exercises.

1. What Are Tenses?

A tense tells us when an action, event, or situation happens.

English mainly uses three time references:

• Present – something happening now or regularly
• Past – something that happened before now
• Future – something expected or planned to happen later

Examples

I study English.
→ Present

I studied English yesterday.
→ Past

I will study English tomorrow.
→ Future

English tenses also show whether an action is simple, continuing, completed, or continuing up to a particular time.

2. The Four Main Tense Forms

Each of the three basic time references can be expressed through four common forms:

This gives learners a useful framework for understanding the 12 commonly taught English tense forms.

Time	Simple	Continuous	Perfect	Perfect Continuous
Present	study	am studying	have studied	have been studying
Past	studied	was studying	had studied	had been studying
Future	will study	will be studying	will have studied	will have been studying

 

3. Simple Present Tense

The simple present tense is commonly used for:

• habits
