Conditionals theory-and-exercises-with-key1

Conditionals
Listed below are examples, uses and formation
of Conditionals followed by some exercises.
Examples Usage
Conditional 0
If I am late, my father
takes me to school.
She doesn't worry if
Julian stays out after
school.
Situations that are always true if something happens.
NOTE
This use is similiar to, and can usually be replaced by, a time
clause using 'when' (example: When I am late, my father takes
me to school.) -See note below-
Conditional 1
If it rains, we will stay
at home.
He will arrive late
unless he hurries up.
Simon will buy a new
car if he gets his raise.
Often called the "real" conditional because it is used for real - or
possible - situations. These situations take place if a certain
condition is met. The first conditional is used to talk about the
future or facts / situations which are true in the present and
future.
NOTE :In the conditional 1 we often use unless which means
'if ... not'. In other words, '...unless he hurries up.' could also be
written, '...if he doesn't hurry up.'.
“Provided” and “as long as” can also introduce a condition:E.g.
“Provided you leave now, you’ll catch the train”
Conditional 2
If he studied more, he
would pass the exam.
I would lower taxes if I
were the Prime Minister.
They would buy a new
house if they won the
lottery.
Often called the "unreal" conditional because it is used for
unreal - impossible or improbable (hypothetical) – situations,
(contrary to the present situation). It is also used to give advice
and express hopes and ambitions.
This conditional provides an imaginary result for a given
situation.
NOTE
The verb 'to be', when used in the 2nd conditional, is always
conjugated as 'were'.
Conditional 3
If he had known that,
he would have decided
differently.
Joanna would have
found a new job if she
had stayed in Gorzów.
Often referred to as the "past" conditional because it concerns
only past situations with hypothetical results. Used to express a
hypothetical result to a past given situation. They always refer
to unfulfilled conditions in the past (contrary to what really
happened).

Notes:
• Temporal clauses: In addition to if and unless, there are other words that are not followed by
the future tense. These words include: before, after, when, whenever, until, till, by the time,
once, the moment that, as soon as, as long as. These words are followed by the Present Simple
even when we talk about the future
When you are ready, we will leave.
Until you are ready, we won't leave.
Before you leave, could you tidy your room?
Whenever I go on holiday, I buy a souvenir.
Mixed Conditions
For past events which have a result continuing in the past it is possible to use the form of a 3rd
conditional in the if clause and the form of a 2nd
conditional in the result clause.
E.g. “If you had saved some money, you wouldn’t be so hard up”.
