CONDITIONAL
SENTENCE
Conditional tenses are
used to speculate about what could happen, what might have happened, and what
we wish would happen. In English, most sentences using the conditional contain
the word if. Many conditional forms in English are used in
sentences that include verbs in one of the past tenses. This usage is referred
to as "the unreal past" because we
use a past tense but we are not actually referring to something that happened
in the past. There are five main ways of constructing conditional sentences in
English. In all cases, these sentences are made up of an if clause
and a main clause. In many negative conditional sentences, there is an
equivalent sentence construction using "unless" instead of
"if".
TYPE 1 CONDITIONAL
The type 1 conditional is
used to refer to the present or future where
the situation is real. The type 1 conditional refers to a
possible condition and its probable result. In these sentences the if clause is
in the simple present, and the main clause is in the simple future.

TYPE 2 CONDITIONAL
The type 2 conditional is
used to refer to a time that is now or any time, and a
situation that is unreal. These sentences are not based
on fact. The type 2 conditional is used to refer to a hypothetical condition
and its probable result. In type 2 conditional sentences, the if clause uses
the simple past, and the main clause uses the present conditional.

TYPE 3 CONDITIONAL
The type 3 conditional is
used to refer to a time that is in the past, and a
situation that is contrary to reality. The facts they are
based on are the opposite of what is expressed. The type 3 conditional is used
to refer to an unreal past condition and its probable past result. In type 3
conditional sentences, the if clause uses the past perfect, and the main clause
uses the perfect conditional.

Wish and If only
Wish and ‘If only’ are both used to talk about
regrets – things that we would like to change either about the past or the
present.

If only I didn’t have so much homework I could go to the concert
tonight. She has a lot of homework and she can’t go to the concert.
When we talk about present regrets, both wish and if
only are followed by the past simple tense. The past tense
emphasises that we are talking about something ‘unreal’.

I
wish I’d studied harder when I was at school. He didn’t study harder when he
was at school.
Both wish and if only are
followed by the past perfect tense when we talk about past
regrets.
Wish/if only and would
We use wish + would to talk about something in the present that we would like to change – usually something that we find annoying.

NB We
can only use wish + would to talk about things we
can’t change.

possible although we can say I wish I didn’t eat so much chocolate.
