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.

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.

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.

• 1. If I ……..a singer, I…… travel a lot.• 2.I ……..  …….. money If I ………a  job.• 3. If  my  dad …….a rich person I ……… study in USA.• 4. If  my mother ………to the market, she ……..buy an ice-cake for me.• 5.
