Unit 4
1 . First Conditional
USE:
a. Nature: Open condition, what is said in the condition is possible.
b. Time: This condition refers either to present or to future time.
If he is late, we will have to go without him.
If my mother knows about this, we are in serious trouble.
ü A first conditional sentence consists of two clauses, an "if" clause and a main clause:
if clause
|
main clause
|
If you study hard,
|
you will pass the test.
|
ü If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:
main clause
|
if clause
|
You will pass the test
|
if you study hard.
|
ü We use different verb forms in each part of a first conditional:
if clause
|
if + subject + simple present verb
|
main clause
|
subject + will + verb
|
Using the First Conditional
The first conditional is used to talk about things which are possible in the present or the future -- things which may happen:
Example
|
