3. Conditional Sentences
Structure :
A conditional sentence is composed of 2 parts :
If-clause + Main Clause
Example :
If it rains tomorrow, we will put on rain coats.

4.  Conditional Sentences
The order of the two clauses is flexible.
When the if-clause comes first, it must be followed by a
comma.
If it rains, I'll stay at home.
I'll stay at home if It rains.

5. 3 MAIN TYPES:
First, second and third
conditional

6. First Conditional
If I see Andrew at the meeting, I'll give him your message.
PRESENT SIMPLE FUTURE SIMPLE
USE: To talk about something that is quite likely
to happen in the future. It is very possible that I
will see Andrew at the meeting, in which case I'll
give him your message. The condition is quite
likely to be fulfilled. For presenting future
plans, real possibilities, steps in an argument,
points in a procedure, predictable consequences,
instructions.

7. Second Conditional (Hypothetical)
If my parents were alive, they would be very proud of me now.
PAST SIMPLE WOULD + INFINITIVE
USE: To talk about a present situation which is impossible, a
hypothetical situation. The situation cannot be fulfilled because my
parents are not alive.
If she changed her job, she'd be much happier.
USE: To talk about a future event which is unlikely to happen. The
speaker doesn`t expect her to change her job. That is, it is unlikely
that the condition will be fulfilled.
What would happen if…?

8. Third Conditional
If she had worked harder, she would have passed her exams.
PAST PERFECT WOULD + PERFECT INFINITIVE
USE
USE: To talk about something that might have happened
in the past, but didn`t. She didn`t work hard enough
and, consequently, she didn`t pass her exams.
It also expresses excuses, regrets and blame for past
events.
What would have happened if…?

9. The zero conditional (factual)
What happens if…?
If I stay out late, I always take a taxi home.
PRESENT SIMPLE PRESENT SIMPLE
USE: To describe something that is generally true. The use of if here
is very similar to when. For presenting habits, general truths, rules,
typical patterns, correlations.
We can also use the past simple in the two clauses.
If I stayed out late, I always got a taxi home.

10. Conditional Sentences: Variations in
tenses
First Conditional: The if clause is usually in the present
simple. However, we can also use:
 Present continuous:
If he's still waiting for you, he'll be very angry.
 Present perfect simple:
If Rob's received your letter, he'll phone you.
 Present perfect continuous:
If it's been raining all night, you'll have to wear boots.
 Can: If I can finish work early, I'll help you.
 Should: If I should see him, I'll tell him the news.

11. The main clause usually has the verb will / shall.
But we can also use:
 Going to:
If Helen passes her exams, I'm going to buy her a present.
 Future continuous:
If we book this holiday, we'll be lying on the beach in two weeks` time.
 Future perfect:
If they win the next match, they'll have won every match in the season.
 Imperative:
If you need me, call me.
 Can / could, may / might, should / ought to,
must
If you don't eat your dinner, you can't have an ice cream.

12. Tense variations in conditional 2
The if clause usually takes the past simple. However,
it is also possible to use:
 Past continuous:
Past continuous:
If you were coming with me, I`d give you a lift.
If you were coming with me, I`d give you a lift.
 Could
Could
If I could have the day off, I`d go with you.
If I could have the day off, I`d go with you.
Were / was to:
Were / was to:
If you were to ask Steve, I`m sure he would do it.
If you were to ask Steve, I`m sure he would do it.

13. The main clause usually has the modal would + infinitive. However, the modals
could and might are also used and the infinitive can be in the continuous
form:
 If we had more money, we wouldn`t be living
here.
 If we had more money, we could go out more.
 If you asked Tony, he might do it for you.

14. Tense variations in conditional 3
The if clause is usually in the past perfect simple. However, we can also use the past
perfect continuous or could + perfect infinitive.
If he had been travelling in the car, he would have
been killed too.
If we could have got a taxi, we would have come
round to see you.

15. The main clause usually has the modal would + perfect infinitive. However, we
can also use the modals could and might + perfect infinitive.

19. IMPLIED CONDITIONALS
Conditions are not always expressed in the form
of conditional clauses, particularly in spoken
English. They can be expressed in another way or
they may be evident from the context. The rules
for the verb usage are still followed in the result
clause (main clause).
He committed the crime, otherwise he wouldn’t have
been arrested. (implied conditional)
If he hadn’t committed the crime, he wouldn’t have been arrested.
I would have stayed longer, but he didn’t ask me to.
(implied conditional)
I would have stayed longer if he had asked me to.

20. Inversion
 If the first verb in a conditional if clause is
should, were or had, we can leave out if and
put the verb at the start of the clause. We do
this particularly in formal or literary English.
 Should any of this cost you anything, send me the
bill (If any of this should…)
 It would be embarrassing were she to find out the
truth. (… if she were to find out…)
 Had they not rushed to hospital, Dan would have
died. (If they hadn`t rushed…)

21.  We use if it was / were not for + noun to say
that one situation is dependent on another
situation.
 If it wasn`t / weren`t for the fireman, my dog would
have died in the fire.
 If it hadn`t been for my parents, I wouldn`t have gone
to university.
 We also use but for + noun with a similar
meaning:
 But for Jim`s support, I wouldn`t have got the
job.

22.  In real conditional sentence, we use
If… happen to,
If … should,
If … should happen to
to talk about something that may be possible but is not very likely:

If you happen to be in our area, drop in and see
us.
 If you should be in our area, …
 If you should happen to be in our area, …

23. Polite requests
 We can use if… will in requests:
o If you will take your seats, ladies and gentlemen,
we can begin the meeting.
 if you want to make a request more polite, you can use if…would:
o If you would take your seats, …
