The subjunctive mood is one of the
more difficult tenses in the English language. The subjunctive mood uses the past tense or the past perfect tense to
indicate a wishful thinking or an action that is not likely to happen or did
not happen in the past.
e.g. If
I were you,
I would accept the
offer. (i.e. the offer is good, do accept it NOW)
e.g. If
I were you,
I would have accepted the
offer last week. (i.e. you didn't accept the offer)
e.g. If
you had called the
doctor, the patient would have
lived. (i.e. you did not call the doctor; the patient did not
live)
e.g. If
pigs had wings,
they would fly.
(i.e. pigs don't have wings, and that's why they don't fly)
e.g. If
he has the
money, he will help you.
(i.e. he may have the
money; if he does, he will certainly help you)
e.g. If
he had the
money, he would help you.
(i.e. he doesn't have the money NOW; therefore, he will not help you)
e.g. If
he had the
money, he would have helped you.
(i.e. he didn't have the money, and that's why he didn't help you)
Remember
this: using past tense for
a present action indicates the improbability of that action, while using
the past perfect tense,
the improbability of that action in the past.
