IF AND THE
CONDITIONAL
There are four main types of 'if' sentences
in English:
|
'IF'
CLAUSE
|
MAIN
CLAUSE
|
|
If + simple present
If you heat ice If it rains |
simple present
it melts. you get wet |
In these sentences,
the time is now or always and the situation is real
and possible. They are often used to refer to general truths.
2. The Type 1 conditional, where the tense in
the 'if clause is the simple present, and the
tense in the main clause is the simple future
|
'IF'
CLAUSE
|
MAIN
CLAUSE
|
|
If + simple present
If it rains If you don't hurry |
Simple future
you will get wet we will miss the train. |
In these sentences,
the time is the present or future and the
situation is real. They refer to a possible condition and
its probable result.
3. The Type 2 conditional, where the tense in
the 'if' clause is the simple past, and the tense
in the main clause is the present conditional:
|
'IF'
CLAUSE
|
MAIN
CLAUSE
|
|
If + simple past
If it rained If you went to bed earlier |
Present conditional
you would get wet you wouldn't be so tired. |
In these sentences,
the time is now or any time, and the situation is unreal.
They are not based on fact, and they refer to an unlikely
or hypothetical condition and its probable result.
4. The Type 3 conditional, where the tense in
the 'if' clause is the past perfect, and the tense
in the main clause is the perfect conditional:
|
'IF'
CLAUSE
|
MAIN
CLAUSE
|
|
If + past perfect
If it had rained If you had worked harder |
Perfect conditional
you would have got wet you would have passed the exam. |
In these sentences,
the time is past, and the situation is contrary to reality.
The facts they are based on are the opposite of
what is expressed, and they refer to an unreal past condition and
its probable past result.
A further type of 'if' sentence
exists, where Type 2 and Type 3 are mixed. The tense in the'if' clause
is the past perfect, and the tense in the main clause is the present
conditional:
|
'IF'
CLAUSE
|
MAIN
CLAUSE
|
|
If + past perfect
If I had worked harder at school If we had looked at the map |
Present conditional
I would have a better job now. we wouldn't be lost. |
In these sentences,
the time is past in the 'if' clause, and present in
the main clause. They refer to an unreal past condition and
its probable result in the present.

EXCEPTION Conditional with Modal Verbs
There are some special conditional forms for modal verbs in
English:
would + can = could
would + shall = should
would + may = might
would have + shall = should have
would have + may = might have
would have + can = could have
The words "can," "shall" and "may"
cannot be used with "would." Instead, they must be used in these
special forms.
