There are four types of conditional sentences in English. The document focuses on the zero conditional and first conditional. The zero conditional describes situations that are always true using the present simple tense in both clauses, such as "If I go to school, I get up at seven." The first conditional is used to speculate about possible future situations and uses "if" clauses with the present tense and main clauses with "will" plus the infinitive verb, such as "If he studies hard, he'll pass the exams." Examples are provided for both types of conditional sentences.

2. THERE ARE FOUR BASIC TYPES
OF CONDITIONAL SENTENCES IN THE
ENGLISH LANGUAGE.
Let’s see just two:
• Zero conditional: I take my
umbrella if it rains.
• First conditional: I'll call you if I
work late.

3. THE ZERO CONDITIONAL
SIMPLE PRESENT + SIMPLE PRESENT
The zero conditional describes situations that
are always true.
*If I go to school, I get up at seven. (Whenever I
go to school I get up at the same time.)
* If you park your car on double yellow lines, you
pay a fine. (Whenever you park illegally, you pay a
fine.)
We use the present simple tense in both the
main clauses and the if clauses.

4. THE FIRST CONDITIONAL
WILL + IF + VERB IN PRESENT
• The first conditional sentences are used to
speculate about possible situations that
can really happen at present or in future.
• If he studies hard, he'll pass the exams. If we
catch the 10.15 train, we will arrive on time. If
you don't get the ticket, what will you do?
We make if clauses with if + present
tense and main clauses with will + infinitive
verb.

job.
