Zero and First Conditional

Conditionals

Conditionals

• A conditional in English is made up of two main parts: An conditional clause and a result clause.

• Example: If you don't come inside, you'll get wet.

Zero Conditional

The zero conditional is used to describe the causes and results of events that we know for a fact. The result is always true.

Example: When it rains, birds fly to other trees for protection.

The conditional clause in Zero conditional can start with IF or WHEN.

Zero Conditional

For the zero conditional we use the PRESENT SIMPLE in both the conditional and the result clauses.

Ex. 1: When a bird loses its mate, it stays single for the rest of its life.

Ex. 2: If you don't eat enough iron, you become anemic.

To summarize...

• Always true

• If X happens, Y happens

• Present Simple + Present Simple

First Conditional

We use the first conditional to make predictions about the future.

Example: If you don't finish your vegetables, mom's going to be mad.

The conditional clause can start with IF, UNLESS, and IN CASE.

UNLESS means only if not and we always use it with an affirmative sentence. (Unless you finish your vegetables, mom's going to be mad).

First Conditional

For the first Conditional, we use the SIMPLE PRESENT in the conditional clause, and a FUTURE TENSE in the result clause.

Ex. 1: If you come home late, I'm not opening open the door.

Ex. 2: Unless you go to the dentist, you won't know why your teeth hurt.

To summarize

• Predictions and possible situations.

• If X happens, Y will happen

• PRESENT SIMPLE + FUTURE TENSE
