Key Points

1. Simple Future Tense

The Simple Future is used to talk about:

• Actions that will happen in the future
• Predictions about the future

Structure

Affirmative:

Subject + will + V1 + complement

Negative:

Subject + will not + V1 + complement

Question:

Will + subject + V1 + complement?

Examples

I think you will not pass the test.

Questions:

will vs. be going to

Both can refer to the future, but they are commonly distinguished as:

• will → decisions/actions not previously planned or predictions
• be going to → planned or intended future actions

Examples:

I am going to come.
We are going to have a class.
She is going to go home.

With be going to:

• am → I
• is → singular subjects
• are → plural subjects

2. Future Progressive / Continuous

The Future Progressive describes an action that will be in progress at a particular time in the future.

Structure

Affirmative:

Subject + will be + V-ing

Negative:

Subject + will not be + V-ing

Question:

3. Past Perfect Tense

The Past Perfect describes an action that was completed before another action in the past.

 earlier           later

Tense Comparison

7. Sentence

A sentence is a group of words that communicates a complete concept or thought.

A complete sentence normally contains:

Subject + Predicate

It:

• Begins with a capital letter.
• Communicates a complete idea.
• Ends with appropriate punctuation.

Example:

The students study English.

Here:

Subject   → The students
Predicate → study English

8. Essential Parts of a Sentence

There are two essential parts:

Subject

The subject tells us who or what the sentence is about.

Example:

The students study English.
      ↑
   Subject

Predicate

The predicate tells us what the subject does, is, or experiences.

The students | study English.
   Subject   |   Predicate

Examples:

I watch TV every night.
They wash their clothes.
He will come next week.
We should write an article.
The students completed the assignment.

9. Clause

A clause is a group of words containing a subject and a verb.

Clause = Subject + Verb

There are two main types:

Independent Clause

An independent/main clause:

• Has a subject and verb.
• Expresses a complete meaning.
• Can stand alone as a sentence.

Example:

He goes home.

Dependent Clause

A dependent/subordinate clause:

• Has a subject and verb.
• Does not express a complete meaning by itself.
• Usually depends on an independent clause.

Examples:

Because she works
If he studies hard
After I finished my work
Before he called me
As we woke up

For example:

Because she works, she earns money.

Because she works is dependent, while she earns money is independent.

10. Subordinating Conjunctions

These words commonly introduce dependent clauses.

Example:

Although it was raining, we went to class.

11. Simple Sentence

A simple sentence contains one independent clause.

It can have:

• A simple or compound subject
• A simple or compound verb

But it has only one independent clause.

Examples:

The teacher explained the lesson.
Ali studied chemistry.
We practiced simple present tense.
They play football.
Jawed watched a movie.

12. Compound Sentence

A compound sentence contains two or more independent clauses.

The clauses can be joined using:

• Coordinating conjunctions
• A semicolon

FANBOYS

F = for
A = and
N = nor
B = but
O = or
Y = yet
S = so

Examples:

They watched a movie, and we slept.

I helped him, but he betrayed me.

You can live here, or you can go.

She studied hard, yet she failed the test.

A semicolon can also join closely related independent clauses:

The weather was cold; we stayed indoors.

13. Complex Sentence

A complex sentence contains:

1 Independent Clause + at least 1 Dependent Clause

Examples:

I went home because I was tired.

If I become the supreme leader, I will open girls' schools.

Although she was tired, she continued studying.

Comma Rule

When the dependent clause comes first, use a comma:

Because I was tired, I went home.

When the independent clause comes first, a comma is generally not needed before a dependent clause beginning with a subordinating conjunction:

I went home because I was tired.

Sentence Type Comparison

14. Punctuation

Punctuation marks help make the meaning of written language clear.

Period .

Used at the end of a statement.

The teacher explained the lesson.

It can also end an imperative:

Sit down.
Please stand up.

Question Mark ?

Used at the end of a direct question.

What is your name?
Where do you live?
Can you speak English?

A statement can sometimes be spoken with rising intonation to function as a question:

He is your brother?

Exclamation Mark !

Used to express strong feeling or emphasis.

I got the first position!
We must go to class on time!

In formal/academic writing, excessive exclamation marks should generally be avoided.

Comma ,

Common uses include:

1. Separating items in a list
2. Following an introductory dependent clause
3. Following an introductory phrase
4. Before a coordinating conjunction joining independent clauses

Examples:

He bought a pen, a book, a bag, a chair, and a desk.

Because he didn't study, he failed the test.

Unfortunately, I failed the test.

He went to school, but I played soccer.

Semicolon ;

A semicolon can join two closely related independent clauses.

We went home; they stayed at the university.

She studied hard; she passed the interview.

Ahmad opened the door; I entered the room.

Colon :

A colon can introduce a list or explanation.

He bought the following items: a pen, a book, a bag, and a desk.

15. Avoiding Run-ons and Comma Splices

A comma splice occurs when two independent clauses are joined only with a comma.

Incorrect:

I was tired, I went home.

This can be corrected in several ways.

Period

I was tired. I went home.

Semicolon

I was tired; I went home.

FANBOYS

I was tired, so I went home.

16. Capitalization

Important capitalization rules include:

First Word of a Sentence

He is a professor.

Not:

he is a professor.

Pronoun I

Always capitalize I.

I am an engineer.
Who am I?

Proper Nouns

Names of specific people, places, institutions, etc.

Afghanistan
Kabul
Kardan University

Days, Months, and Holidays

Monday
August
Eid
24th Asad

Names and Titles

Professor Ahmad
Jawed
Fatime
Putin
Zabihullah

17. Capitalization in Titles

Important words in titles are generally capitalized.

Examples:

World War Two
Presidential Election
World Cup
Life in a Jungle
Life and Death
A King with No Power
On Mars
Now and Then

Generally, short:

• Articles: a, an, the
• Prepositions: in, on, from, out, etc.
• FANBOYS: for, and, nor, but, or, yet, so

are not capitalized when they occur in the middle of a title, unless the applicable style guide says otherwise.

        ↓

I will be studying.

PAST PERFECT

Sentence Structure

Remember the hierarchy:

Sentence
   ↓

Clause(s)
   ↓
each clause contains
   ↓
Subject + Verb

Then classify the sentence based on its clauses:

1 Independent clause
       ↓
    Simple

2+ Independent clauses
       ↓
    Compound

1 Independent + 1+ Dependent
       ↓

Common Mistakes

Tenses

• Using V1 after had instead of V3.

  • ❌ had went
  • ✅ had gone

• Forgetting -ing in continuous tenses.

  • ❌ will be study
  • ✅ will be studying

• Forgetting been in perfect continuous tenses.

  • ❌ will have teaching
  • ✅ will have been teaching

• Using will + V-ing.

  • ❌ will studying
  • ✅ will be studying

Sentences

• A dependent clause cannot normally stand alone.

  • ❌ Because I was late.
  • ✅ Because I was late, I missed the class.

• Do not join two independent clauses with only a comma.

  • ❌ I was tired, I went home.
  • ✅ I was tired, so I went home.

• Do not confuse a compound sentence with a complex sentence:

  • Compound → independent + independent
  • Complex → independent + dependent

Punctuation & Capitalization

• ❌ i live in kabul.

• ✅ I live in Kabul.

• ❌ we have class on monday.

• ✅ We have class on Monday.

• Avoid unnecessary exclamation marks in academic writing.

• Remember that a semicolon requires independent clauses on both sides.

• When an introductory dependent clause comes first, normally place a comma after it.
