Zero - 3rd conditionals. I've edited and prepared a simple 1 for my Junior 3 (Form 3) students. Dear teachers, Please feel free to download and use it for your lesson. :)

1. Zero conditional
*If + present simple, .... present simple
-This conditional is used when the result will always happen.
So, if water reaches 100 degrees, it always boils. It's a fact.
Examples:
If people eat too much, they get fat.
If you touch a fire, you get burned.
If babies are hungry, they cry.

2. First conditional
*If + present simple, ... will + infinitive
-This conditional has the present simple after 'if', then the future
simple in the other clause.
-It's used to talk about things which might happen in the future.
Examples:
 If it rains, I won't go to the park.
 If I study today, I'll go to the party tonight.
 If I have enough money, I'll buy some new shoe.

3. Second conditional
*If + past simple, ... would + infinitive
-To talk about the hypothetical consequences of future events which are,
unlikely, improbable, impossible or unrealistic.
-This conditional can only refer to future events (things which have not
happened at the time of speaking).
Examples:
 If he failed the exam, I would be surprised.
 If I won the lottery, I would buy a house in San Fransisco.
 I would look for a new job if my boss didn't give me a pay rise.

4. Third conditional
*If + past perfect, ...would + have + past participle
-Made using the past perfect after 'if' and then 'would have' and the past
participle in the second part of the sentence
-It talks about the past. It's used to describe a situation that didn't happen, and to
imagine the result of this situation.
Examples:
 If she had studied, she would have passed the exam (but, really we know
she didn't study and so she didn't pass)
 If I hadn't eaten so much, I wouldn't have felt sick (but I did eat a lot, and
so I did feel sick).

5.  The Zero Conditional:
(if + present simple, ... present simple)
 The First Conditional:
(if + present simple, ... will + infinitive)
If it rains tomorrow, we'll go to the cinema.
 The Second Conditional:
(if + past simple, ... would + infinitive)
If I had a lot of money, I would travel around the world.
 The Third Conditional:
(if + past perfect, ... would + have + past participle)
If I had gone to bed early, I would have caught the train.
