[tex] \boxed{ \sf{Conditional \: sentence}}[/tex]
Sentences containing conditional clauses like 'if' , 'unless and 'provide that' are called conditional sentences. There are four types and express four types of meaning.
[tex] \star{ \text{ \: Type \: zero}} : [/tex] It always expresses real and possible.
- If + simple present : simple present ( for scientific facts )
Example: If water is boiled , it changes into water vapour.
- If + simple present : Imperative
Example: If you want to win, play fair.
[tex] \star{ \text{ \: Type \: one}}[/tex] : It expresses possible situation in the present or future.
- If + simple present : will / shall / can / may / must + V¹
Example : I shall play football if I get chance.
[tex] \star{ \text{ \: Type \: two}}[/tex] : It expresses doubtful situation / hypothetical condition in the present or future
- If + simple past : would / should / could / might + v¹
Example : If I were you , I would never accept the proposal.
Note: ' Be' verb in if clause always becomes ' were ' ( only in conditional sentence type two)
[tex] \star{ \: \text{ \: Type \: three}}[/tex] : It expresses regret / unfulfilled situation in the past.
- If + past perfect : would / should / could / might + have + v³
Example : He would have helped you if you had asked him.
[tex] \star { \: \text{ Unless : if \: not}}[/tex]
' Unless ' has the similar structure like ' if ' but it gives negative / situational meaning.
Example : She wouldn't learn much unless she worked harder.
[tex] \star{ \text{ \: Provided \: that : if}}[/tex]
' Provided that ' functions like ' if ".
Example: Provided that you were a teacher , what would you do?
[tex] \star{ \text{ \: Inversion}}[/tex]
The auxiliary verb of conditional sentence type two and three can be fronted in place of ' if'
Example: Were I a bird , I would fly.
