"Conditional If"

1.Type 1 - Present Tense (can be real in the future)
2.Type 2 - Past Tense (contrary to the fact in the present)
3.Type 3 - Past Participle (contrary to the fact in the past)

Patterns
TYPE 1 = (present tense + future tense) can be real in the future
+ IF + V1/s/es[is/am/are] + O [A/N/A] , S + will [will be] + V1 [A/N/A] + O
- IF + S + doesn't/don't + V1 + O , S + will not + V1 + O

TYPE 2 = (simple present tense + past future tense) contrary to the fact
+ IF + S + V2 [were] + O [A/N/A] , S + would [would be] + V1 [A/N/A] + O
- IF + S + didn't [weren't] + O [A/N/A] , S + wouldn't [wouldn't be] + V1 [A/N/A] + O

TYPE 3 = (past perfect + past future perfect) contrary to the fact in the past
+ IF + S + had [had been] + V3 [A/N/A] + O , S + would have [would have been] + V3 [A/N/A] + O
- Had [had+S+been] + S + V3 + O , S + would have [would have been] + V3 + O


Rules :
1. If the fact is (+) so the cond. is (-)
If the fact is (-) so the cond. is (+)

2. FACT -> CONDITIONAL
Type 1 -> Type 2 -> Type 3
CONDITIONAL - FACT
Type 3 -> Type 2 -> Type 1

3. CONDITIONAL -> FACT
would -> don't, doesn't, can't, will not, shouldn't, is/am/are, was/were

Ex.

Fact : I don't have enough time
a : I wish I had enough time
b : If I had enough time, I would go to the park
