CONDITIONAL
SENTENCES
5. A full conditional sentence (one that
expresses the condition as well as its
consequences) therefore contains two
clauses: the dependent clause expressing
the condition, called the protasis; and the
main clause expressing the consequence,
called the apodosis.
Example: If you study, then you will pass.
6. In English language teaching, conditional
sentences are often classified under the
headings zero conditional, first conditional,
second conditional, and third conditional.
7. ZERO CONDITIONAL
It refers to conditional sentence that is
used for present, real or factual
situations, particularly when both clauses
are in the present tense.
Examples:
1. If you heat water, it boils.
2. You burn yourself if you touch a flame.
8. FIRST CONDITIONAL
It refers to conditional sentence that is
used for future real or factual situations
and to express a simple statement of fact
or intent.
Examples:
1. If I win the lottery, I will buy a new car.
2. I will let you know if you make a mistake.
9. SECOND CONDITIONAL
It refers to conditional sentence that is
used for future unreal or imaginary
situations or to a situation in the future
that the speaker thinks is unlikely to
happen.
Examples:
1. If I won the lottery, I would buy a new car.
2. I would travel around the world if I had a
lot of money.
10. THIRD CONDITIONAL
It refers to conditional sentence that is
used for past unreal, imaginary situations
or situations that did not happen.
