========================================================================

Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.
========================================================================

Conditional Sentence Type 1

Often called the "real" conditional because it is used for real or possible situations. These situations take place if a certain condition is met. It is possible and also very likely that the condition will be fulfilled.

Form : If + Simple Present, + Simple Future

Use :

Conditional Sentences Type 1 refer to the future. An action in the future will only happen if a certain condition is fulfilled by that time. We don't know for sure whether the condition actually will be fulfilled or not, but the conditions seems rather realistic – so we think it is likely to happen.

Example : 

If clause	Main or Conditional clause
If + Present Tense	Future Tense
If they are late,	I’m going to be angry.
If I have enough time,	I'll watch the football match.

========================================================================

Conditional Sentence Type 2

Often called the "unreal" conditional because it is used for unreal impossible or improbable situations. This conditional provides an imaginary result for a given situation. It is very unlikely that the condition will be fulfilled.

Form : if + Simple Past, + would + base verb

Were / Was

In conditional type 2, we usually use in the if clause "were" instead of "was" even if the pronoun is I, he, she or it. "were" here is a subjunctive form.

NOTE : "was" is also a possible form.

Use :

Conditional Sentences Type 2 refer to an action in the present that could happen if the present situation were different. I don't really expect the situation to change because it is very unlikely.

Example : 

If clause	Main or Conditional clause
If + Simple Past	would + base verb
If I were a millionaire	I would buy a castle.
If I had time,	I would drop you off at school.

========================================================================

Conditional Sentence Type 3

It is impossible that the condition will be met because it refers to the past.

Form: if + Past Perfect, + would + have + Past Participle

Use :

Conditional Sentences Type 3 refer to situations in the past. They express hypothetical results to past given situations.

Example : 

If clause	Main or Conditional clause
If + Past Perfect	would + have + Past Participle
If he had been careful,	he wouldn't have had that terrible accident.
If we had known about the storm,	we wouldn’t have started our journey.

========================================================================

Things to remember!

1. The main clause can also be at the beginning of the sentence. In this case, don't use a comma.

Example :

• "Phosphorus burns if you expose it to air."
• " I will send her an invitation if I find her address."
• " I would travel around the world if I had a million dollars."
• "He wouldn't have had that terrible accident if he had been careful." 

2. Main clause and/or if clause might be negative.  

Example :

• If I don’t see him this afternoon, I will phone him in the evening.
• If he had been careful, he wouldn't have had an accident.
