2 0 - 6 Using “Mixed Time” in Conditional Sentences
Frequently the time in the /'/-clause and the time in the result clause are different: one clause may be in the present and
the other in the past. Notice that past and present times are mixed in these sentences.
(a)
True:
I
did not eat
breakfast several hours ago, so I
am
hungry now.
(b)
Conditional: If I
had eaten
breakfast several hours ago, I
would not be
hungry now.
(past)
(present)
(c)
True:
He
is not
a good student. He
did not study
for the test yesterday.
(d)
Conditional: If he
were a
good student, he
would have studied
for the test yesterday.
(present)
