                                               REMEMBER

a) Open conditional (First conditional) :-

Open conditional sentences are sometimes called the ‘first’ or ‘future’ conditionals. Both clauses in a sentence refer to the future, although the verb in the ‘if- clause’ is in the present tense.

No	If- clause	Conditional clause
Rule	If + Present Tense	Future Form
e.g.	i)If it comes to sacrifice	it will be done
	ii)If there is no water	all living things will die.

b)     Hypothetical / Unreal conditional (Second conditional) :-

Hypothetical conditional sentences refer to or speculate about something that is (or what we perceive to be) impossible or contrary to fact.

The sentences can refer to the present or the future.

No	If- clause	Conditional clause
Rule	If + Past Tense	Would + infinitive (To + main verb)
e.g.	i)   If I won a lottery	I would help the poor.
	ii) If Nile  was  not there   were	Egypt would be a desert

c) Unfulfilled / Past conditionals (Third conditional) :-

We use unfulfilled / Past conditionals to speculate about past events and about how things that happened or didn’t happen might have affected the past events. We use this conditional to express our regret / reproaches or to make excuses.

No	If- clause	Conditional clause
Rule	If + had + Past participle	Would have + Past participle
e.g.	i)If Tejas had participated	he would have won
	in the competition
	ii)If Rahul had invited me.	I would have gone to his place.
