If This Happens, Then That Happens... Yes or No?

Today: Learn to talk about facts that are always true ("if this, then that"), and ask questions that need a yes/no answer — so you can make logical statements and ask for information clearly.

Listen to Two Different Sentences

"If you heat water, it boils."
"Do you like coffee?"

First sentence = what ALWAYS happens. Second sentence = asking for information.

🎙 Speak: What's different about these two sentences?

Hook

Why You Need Both

Zero conditional: For facts. "If you freeze water, it becomes ice." This is always true.

Yes/No questions: For asking. "Do you speak French?" You want a yes or no answer.

Both are in conversations every day. You need them.

Retrieval

Think About Your Life

Think of one thing that always happens in your life — like "If I drink coffee, I can't sleep." Don't say it yet.

🎙 Speak: Tell me something that always happens in your life. Use "if."

Zero Conditional: Facts That Are Always True

Use zero conditional for things that are always true — facts of nature, universal truths, habits that never change.

I Do — Teacher Models

The Pattern: If + present simple, present simple

If you heat water, it boils.
If it rains, the ground gets wet.
If I don't sleep, I'm tired.
If you press this button, the door opens.
If people exercise, they feel better.

Two Important Points

Point 1: Both parts use present simple. No "will" or "would."

✓ "If you eat sugar, you get energy." ✗ "If you eat sugar, you will get energy." (Not zero conditional.)

Point 2: The result ALWAYS happens. It's 100% certain, not maybe.

✓ "If water boils, it makes steam." (Always.) ✗ "If I study, I pass." (Maybe, but not always.)

Real Examples

If someone is late, they miss the beginning.
If it's cold, ice forms on roads.
If you mix red and white paint, you get pink.
If people sit in the sun, they get a sunburn.

Three Zero Conditional Sentences

Make three sentences about facts in nature or your life.

Example: "If I drink coffee, I sleep badly. If it's sunny, I go outside. If people are sick, they go to the doctor."

🎙 Speak: Tell me your three if-sentences now.

Yes/No Questions: Ask for Information

Ask a yes/no question by moving the helping verb to the FRONT. The answer is always "Yes, I/you/he/she do/does/can/will..." or "No, I/you/he/she don't/doesn't/can't..."

I Do — Teacher Models

The Pattern

Statement Question
You like coffee. Do you like coffee?
She speaks English. Does she speak English?
They can swim. Can they swim?
He is tired. Is he tired?
You are ready. Are you ready?

Key Rules

Rule 1: Move the helping verb to the front.

Do/Does, Can, Is/Are, Will, etc. go FIRST.

Rule 2: Subject comes after the verb.

DO you... CAN he... IS she... ARE they...

Rule 3: The main verb stays in base form.

Do you LIKE? (not "do you likes")
