We have been revising first and second conditional.

2. Zero, First and Second
Conditionals

3. Zero Conditional
• Form
• The ‘If' in this conditional can be replaced by 'when' without
changing the meaning
If + present simple, .... present simple

4. When do we use Zero Conditional???
• We use this conditional when the result will always happen
• we use it with facts and general statements
• When we talk in general (not about one particular situation)

5. Examples of Zero Conditional
• If water reaches 100 degrees, it boils.
• If people eat too much, they get fat.
• If you touch a fire, you get burned.
• If babies are hungry, they cry.
facts

6. First Conditional
Form
• The first conditional has the present simple after 'if', then the
future simple in the other clause
if + present simple, … will + infinitive.

7. When do we use First Conditional???
• We use the first conditional to talk about a likely situation or
a possible condition
• To talk about things which might happen in the future
• To describe possible things which could easily come true
• when we talk about one particular situation

8. Examples of First Conditional
• If it rains, I won't go to the park.
• If I study today, I'll go to the party tonight.
• She will miss the bus if she doesn't leave soon.
• If I see her, I will tell her.
possible situations

9. Note:
• Use a comma if the if clause is at the beginning of the sentence.
Example:
If I go to London, I will visit the Tower.
• Don’t use a comma if the if clause is at the end of the sentence.
Example:
I will visit the Tower if I go to London.

10. Zero Conditional vs. First Conditional

11. Second Conditional
• If + past simple, … would + infinitive Form
• The second conditional has the past simple after 'if', then would plus
infinitive in the other clause

12. When do we use Second Conditional???
• We use the second conditional to talk about an unlikely or
imaginary situation or a hypothetical condition
• to talk about things in the future that are probably not going
to be true
• to talk about something in the present which is impossible
because it's not true

13. Examples of Second Conditional
• If I won the lottery, I would buy a big house.
• If I met the Queen of England, I would say hello.
• She would travel all over the world if she were rich.
• She would pass the exam if she ever studied.
These are probably not going to happen
