ZERO AND IMPERATIVE CONDITIONALS

Before we begin, let’s clarify that
there are different types of
conditional structures used for
different contexts or purposes.

Zero conditional.1.

First conditional2.

Second conditional.3.

Third Conditional.4.

Mixed Conditional. 5.

Let’s focus on Zero Cond.

Function: When do we use ZERO COND.?

Zero conditional

It is used to talk
about facts or
things that are

true

(general truths)

If you rest a
lot,

you have more
energy.

If you eat healthy food,
you stay fit.

This is usually

true.

Let’s see some examples

If I oversleep …

I miss the bus.

If I miss the bus, I am late for school.

If I am late for school, my teacher gets angry.

Form

Conditional sentences have two parts (we call
these clauses) – the hypothetical clause and the

result clause. Look…

If Tina studies more, she doesn’t fail her

tests.

Hypothetical

Result

How do we make sentences

in the conditional

structures?

This is also called IF CLAUSE
because it contains the word
IF (si) which introduces the

condition.

You can sometimes replaceif

with when,

e.g. When you rest a lot, you

have more energy.

Form: How do we make sentences in the
Zero Conditional?

If + subject + present
simple
,

subject + present simple

If you mix yellow and blue , you get green

If my mum is angry with me , I don’t go out with friends

If we do exercise

, we stay fit

The result clause can also come before the hypothetical clause, but

then you omit the comma. Look…

You get green if you mix yellow and blue.

I don’t go out with friends is my mum is angry with me.

We stay fit if we do exercise.

Conditional
Imperative

Function: When do we use
CONDITIONAL IMPERATIVE?

Conditional imperative
It is used to give

instructions,

orders or advice

If you are
tired,

take a
rest.

If you want to live, don’t
touch that cable.

This is a piece of

advice.

Let’s see some examples

If you feel sick, go to a doctor

Don’t shout if you don’t want to wake the baby up.

If you go to the city centre, buy some milk

Form: How do we make sentences in the
Conditional Imperative?

If + subject + present simple

,

imperative (verb / don’t + verb)

If Anna can’t do the exercise , help her.

If your mum is a risk patient , don’t let her go out.

The result clause can also come before the

hypothetical clause, but then you omit the comma.

Look…

Help Anna if she can’t do the exercise.

Don’t let your mum go out if she is a risk patient.
