Let’s start with the most important part of English grammar—Tenses.

Chapter 1: Tenses Explained Simply

Tenses are used to express when an action happens: in the present, past, or future.

Mastering tenses is one of the most important steps in learning English.

There are three main tenses, and each has four forms:

Chapter 2: Modal Verbs Made Easy

Modal verbs are special helping verbs that add meaning to the main verb in a sentence.

They show possibility, ability, permission, advice, necessity, or obligation.

Here are the most common modal verbs in English:
can, could, may, might, must, shall, should, will, would

Let’s look at each one with simple explanations and examples.

1. Can – ability or permission

Examples:

• I can swim. (ability)

• Can I use your phone? (permission)

2. Could – past ability or polite request

Examples:

• She could read when she was four. (past ability)

• Could you please open the window? (polite request)

3. May – formal permission or possibility

Examples:

• You may leave early today. (permission)

• It may rain this evening. (possibility)

4. Might – less certain possibility

Examples:

• He might come to the party.

• We might travel next weekend.

5. Must – strong necessity or logical conclusion

Examples:

• You must wear a helmet. (necessity)

• She must be tired after working all day. (deduction)

6. Shall – formal future or suggestion (mostly with “I” and “we”)

Examples:

• Shall we begin the meeting?

• I shall return tomorrow. (formal)

7. Should – advice or expectation

Examples:

• You should drink more water. (advice)

• He should be here by now. (expectation)

8. Will – certain future action or promise

Examples:

• I will call you later.

• She will help you with your homework.

Quick Tips to Remember

• Use can/could for ability and requests.

• Use will/would for future or polite speech.

Practice writing your own examples to make these verbs part of your daily speaking.

Chapter 3: Active vs Passive Voice Explained Simply

In English, we can write sentences in two ways: Active Voice or Passive Voice.

What is Active Voice?

In active voice, the subject does the action.

Structure:
Subject + Verb + Object

Examples:

• The chef cooked dinner.

• She wrote a letter.

These are direct and clear. Most sentences in spoken and written English are in the active voice.

What is Passive Voice?

In passive voice, the object becomes the subject of the sentence. The focus is on the action, not who did it.

Structure:
Object + form of “be” + past participle (+ by + doer)

Examples:

• Dinner was cooked by the chef.

• A letter was written by her.

Sometimes, the “doer” is not mentioned:

• The work was completed.

• The book was published in 2020.

When to Use Passive Voice

• When the doer is unknown:
  My wallet was stolen.

• When the doer is not important:
  The streets are cleaned every day.

• When you want to focus on the action or result:
  A new hospital was built last year.

Changing Active to Passive

Here’s how you change the sentence from active to passive:

Step 1: Move the object to the subject position
Step 2: Use the correct form of “be”
Step 3: Use the past participle of the verb
Step 4 (optional): Add “by” + original subject

Example Conversions

Active	Passive
She sings a song.	A song is sung by her.
They are watching a movie.	A movie is being watched by them.
He wrote a book.	A book was written by him.
We will finish the work.	The work will be finished by us.

Tip to Remember

• Active voice = Clear, direct, strong

• Passive voice = More formal, sometimes vague

Use active voice in most situations, especially in writing emails, stories, and blog posts.

Chapter 4: Articles – A, An, The

Articles are small words we use before nouns.

They help define whether we’re talking about something specific or general.

There are two types of articles:

1. Indefinite Articles: A / An

Use “a” or “an” when you are talking about something not specific or for the first time.

➤ Use “a” before words that begin with a consonant sound

Examples:

• a car

• a book

• a university (“you-ni-ver-si-ty” starts with a consonant sound)

➤ Use “an” before words that begin with a vowel sound (a, e, i, o, u)

Examples:

• an apple

• an umbrella

• an hour (starts with a vowel sound “our”)

Remember: It’s about sound, not spelling.

2. Definite Article: The

Use “the” when you are talking about a specific person or thing, or something that is already known to the listener or reader.

Examples:

• The sun is bright today. (There is only one sun — specific)

• I saw a dog and a cat. The dog was brown. (Second mention)

• Please pass me the salt. (Listener knows which salt)

When NOT to Use Articles

No article with plural nouns when talking in general:

• Dogs are friendly.

• Books can teach us a lot.

No article before names of people, cities, or countries (in most cases):

• I visited India.

• Maria is a teacher.

But some names do use “the”:

• The United States

• The Taj Mahal

• The Himalayas

Quick Comparison

Article	Use	Example
a	one non-specific thing (before consonant sound)	a pencil, a house
an	one non-specific thing (before vowel sound)	an egg, an idea
the	a specific or known thing	the moon, the car we saw

Practice Tip:

Think of “a/an” as the first time you introduce something, and “the” when you’re talking about it again or when it’s already known.

Chapter 5: Prepositions in Use
