2. *There are several structures in English that
are called conditionals.
*Conditional sentences usually consist of two
clauses: a conditional clause (or if clause)
and a main clause (or result clause).
*The result in the main clause is dependent on
the condition in the conditional clause. This
unit looks at the basic types of conditional
sentence, and some variations on these, and
introduces a number of words and phrases
used to express conditions.

any time, and often occur more than once, and their results.
We also use the zero conditional to talk about actions which always have the
same result.
In Zero Conditional sentences If can be replaced by When without violating the
meaning.

8. Second Conditional is formed in this way:
If + Past Simple, would/could/might + infinitive without to
If I had money, I would love to do something like that.
We use Second Conditional to talk about imagined, impossible or unlikely events.
The second conditional has two main meanings.
1. It can describe an improbable future event or situation. The condition is
unlikely to be fulfilled because the future event is unlikely to happen:
If the result of the test were positive, we would call you within two days.
2. It can also describe a hypothetical current situation or event, i.e. one which is
contrary to known facts. It is therefore impossible to fulfill the condition:
If the police were confident of their case against Sykes, surely they wouldn’t
hesitate to take him into custody? (= The police aren’t confident of their case.)

We use Third Conditional to talk about imagined, impossible or
unreal situations in the past or to imagine situations that did not
happened.
The third conditional describes a hypothetical situation or event in
the past. The past situation or event is contrary to known facts, i.e.
it is an unreal or impossible situation.
We can use the third conditional to express criticism:
If you’d been driving more slowly, you could have stopped in time.
