Second conditional
If clause :If i had a fever, Main clause :I would see a Doctor.

If clause If you were sick, Main clause : would you go to school?
FORMULA = If + Subject + Simple past,
Subject + would ('d) + base from of the verb
1 A second conditional sentence can begin with either the if clause or the main clause.
If they were rich, they’d build a new hospital.
They’d build a new hospital if they were rich.
2 In the if clause, We use if + Simple past.
If i had a terrible rash like that…
If he passed all his exams…
3 In the main clause, We use would ('d) / Wouldn’t + base from of the verb.
If i had a teerible rash like that, I wouldn’t leave the house!.
If he passed all his exams, he would have a huge Party.
4 When the if clause comes First in a second conditional sentence, We use a comma (,) at the end of the if clause. We don’t use a comma when the main clause comes first.
If i won the lottery, I’d give the Money to charity.
I’d give the Money to charity if I won the lottery.
5 We use the Second conditional to talk about unlikely or Imaginary situation.
If i live’d in the U.S., I would Know all the English words for illnesses already.
(I Don’t live in the U.S., So this is Imaginary.)
6 Although We use the Simple past in Second conditional sentences, We use the Second conditional to talk about unlikely or Imaginary situation in the present or future (not the past).
If i had My own pool,I’d swim there every day.
( I Don’t have a pool, So this is an Imaginary situation in the present.)
If i Discovered a cure for colds, I’d be famous.
(I probably won’t Discover a cure for colds. So this is an Imaginary situation in the Future.)
