17 – 5 EXPRESSING CONDITIONS IN ADVERB CLAUSES:
IF-CLAUSES
(a) If it rains, the streets get wet
If-clauses (also called “adverb clauses of
condition”) present possible conditions. The
main clause expresses results.
In (a): POSSIBLE CONDITION = it rains
RESULT = the streets get wet
(b) If it rains tomorrow, I will take my umbrella. A present tense, not a future tense, is used in
an if-clause even though the verb in the if-
clause may refer to a future event or
situation, as in (b).*
