3. CONDITIONALS

4. WHAT ARE CONDITIONALS?
• Used to show an if/then relationship between two
actions (sometimes called the If-clauses)
• Used to express that an action or state of being is
conditioned on the occurrence of another action.
• Real Conditional describes real-life situations.
Unreal Conditional describes unreal, imaginary situations.

5. CONDITIONAL
SENTENCES
Structure :
A conditional sentence is composed of 2 parts :
If-clause + Main Clause
Example :
If she calls, I will be very happy.
If-clause Main Clause

6. CONDITIONALS
Zero Conditionals

7. Zero conditionals are used to talk about general
truths, when the result of the condition is always true
like a scientific fact and things that always happen in
a given condition.

8. If you freeze water, it becomes a solid.

9. FORM
Conditional 0 is formed by the use of the present simple in the if
clause followed by a comma, and by the result clause in present
simple.
You can also put the result clause first, without using a comma
between the clauses.
Water becomes solid if you freeze it.
If Condition Result
Present Simple Present Simple
If you freeze water it becomes solid.

10. MORE EXAMPLES:
1. If you cross an international date line, the time
changes.
• Explanation: This always happens, every time you cross a
dateline.
2. If you go 10 meters under water, the pressure increases to
two atmospheres.
• Explanation: This is basically always true -- the pressure of
10 meters of water equals one atmosphere.
3. Phosphorus burns if you expose it to air.
• Explanation: This is a scientific fact -- you can test it in a
laboratory.

11. “When” instead of “If”
Sometimes we use “when” instead of “if”
Both words express law of nature or general truth.
For example:
If it is cold, I stay inside the house.
When it is cold, I stay inside the house.

21. SUMMARY
 Notice that we are thinking about a result that is always true for
zero condition.
 The result of the condition is an absolute certainty. We are not
thinking about the future or the past, or even the present. We are
thinking about a simple fact.
 We use the present simple tense to talk about the condition. We
also use the present simple tense to talk about the result.
 The important thing about the zero conditional is that the
condition always has the same result.
 The first conditional is used to talk about things which are
possible in the present or the future -- things which may happen:
