Explanation and exercises about First Conditional.

1. FIRST CONDITIONAL
It is used to talk about
possibilities in the present or in
the future.

2. FIRST CONDITIONAL
Grammar Structure
We often make conditional sentences by using:
If clause: If + subject + present simple
Main clause: will ( ’ll ) / won’t / might or might not

3. FIRST CONDITIONAL
Example:
If we have time , we’ll go to the cinema.
They might go out tonight if they don´t have
homework

4. UNLESS
We can also use the word unless in conditional
sentences – it means if…not.
Example
Unless the teacher explains, we wont know what to do.
Explanation
If the teacher doesn’t explain, we wont know what to
do.

5. UNLESS
Example
Liz won´t know unless you tell her.
Explanation

6. FIRST CONDITIONAL:TWO CLAUSES
There are two clauses in these sentences.
We can put the main clause first, or the if/unless clause
first.
When the if/unless clause comes first, there is a
comma ( , ) after it.
Example:
If She does all her homework , she’ll go out tonight.
I’ll be happy tomorrow if I win the match.
