CONDITIONALS
CONDITIONALS
What are conditionals?
Conditionals have two clauses: a main clause and an if clause.
The main clause expresses a consequence of if:
I can’t sleep well if I’m not tired
CONDITIONALS
What are conditionals?
Where the main clause comes first there is no comma
between the two clauses. When the if clause comes first a
comma is necessary to separate them.
I can’t sleep very well if I’m not tired.
If I’m not tired, I cant sleep very well.
REAL CONDITIONALS
What are real conditionals?
They describe situations that occur regularly or are
reasonably likely to occur. You can recognise them by the
choice of tense in each clause.
Where the main clause uses the present simple, its describing
a situation that’s usually true- just like the normal use if the
present simple:
If you heat water to 100 degrees, it boils.
REAL CONDITIONALS
What are real conditionals?
We sometimes call conditionals, where both clauses use the
present simple, zero conditionals. These are the most
common.
They are used for things that generally happen and are always
true; such as scientific truths and generalisations:
If I find something challenging, I get more excited.
REAL CONDITIONALS
What are real conditionals?
We sometimes use present continuous instead of present
simple. When this happens the conditional still expresses
general truths:
When it’s not raining, I walk to my lectures.
REAL CONDITIONALS
What are real conditionals?
Where the main clause uses a modal verb (will, may, might,
could, should) in its usual form it shows that something is
possible or likely in the future:
If I’m tired at night, I may go to bed.
REAL CONDITIONALS
What are real conditionals?
When they have present simple in the if clause and modal
verbs in their usual form in the main clause they are
sometimes called first conditionals.
We use them to talk about possible or likely events and
situations in the future.
If this experiment succeeds, I’ll be very pleased.
If you don’t try, you won’t succeed.
REAL CONDITIONALS
What are real conditionals?
If you put a modal verb in the main clause of a zero
conditional, you get a first conditional.
Notice how the action of the modal verb changes the
meaning:
If I’m tired at night, I go to bed.
If I’m tired at night, I may go to bed.
RECAP
Zero conditionals- generally happen; always true (e.g. scientific
truths):
If you heat water to 100 degrees, it boils.
First conditionals- possible likely events and situations in the future:

CONJUNCTIONS
Using another conjunction instead of if
Even if, whether…or not…
• The project will continue even if funding isn’t available.
• The project will continue whether or not funding is available.
• The project will continue whether funding is available or not.
See how even if + negative verb has the same meaning as whether
or not + positive verb.

HYPOTHETICAL CONDITIONALS
What are hypothetical conditionals?
They describe things that are unlikely to
happen or will never happen.
HYPOTHETICAL CONDITIONALS
Unreal and future conditionals:
The if clause describes an event or situation. Where this
uses the past simple or past continuous, we see the event
or situation as unlikely, unrealistic or impossible.
By moving the tense backwards, from present to past, we
make the action seem distant from reality.
HYPOTHETICAL CONDITIONALS
• Changing will in the main clause to would also
creates a sense of distance from reality. Changing
can to could has the same effect.
• Would is often shortened to ‘d especially in
speaking.
HYPOTHETICAL CONDITIONALS
Where the if clause uses the past simple and the main clause uses a
past modal, we call this second conditional. Look at the sentences
below:
If I finish my assignment tomorrow, I’ll be happy.
If I finished my assignment tomorrow, I’d be happy.
In the first sentence, a first conditional, the speaker feels there is a
good chance she will finish her assignment tomorrow. In the second, a
second conditional, she feels that this is much less likely.

HYPOTHETICAL CONDITIONALS
Unreal past conditionals:
• Where the if clause uses the past perfect, it refers to something in
the past that didn’t happen.
If I’d had a car…
• Where the main clause uses would/ could/ might/ may + have/has +
past participle it refers to a past consequence or result that didn’t
happen.
I would have given you a lift.
We sometimes shorten would to ‘d just like had.
HYPOTHETICAL CONDITIONALS
Unreal past conditionals:
When we use a combination of these things we call it a third
conditional:
If I’d had a car, I’d have given you a lift.
If the research had involved more students, the results might
have indicated even less average sleep time.
HYPOTHETICAL CONDITIONALS
Unreal past conditionals:
Tenses can also vary, e.g. we can use the past perfect
continuous.
If it hadn’t been raining, I wouldn’t have got wet.
HYPOTHETICAL CONDITIONALS- RECAP
Second conditionals- the if clause uses the past simple and the main
clause uses a past modal. Unlikely and unrealistic:
If I finished my assignment tomorrow, I’d be happy.
Past simple
Past modal
Third conditionals- the if clause uses the past perfect the main clause uses
would/ could/ might/ may + have/has + past participle, refers to something
in the past that didn’t happen.
If I’d had a car, I’d have given you a lift.
Past perfect Would (modal) Have Past participle

VERB PATTERNS
Many verbs are followed by a specific pattern of words. This
pattern can vary from verb to verb.
The following example follows verb + infinitive:
The professor wanted to know the number of people who
were expected to attend his lecture.
VERB PATTERNS
Direct objects: In the below example, the public health service
is a direct object of consider:
subject
verb
object
The government considered the public health service to be of
primary importance.
VERB PATTERNS
Direct objects: usually noun phrases
A noun phrase is a single noun, a pronoun or a group of
words that act like a noun.
He wanted Sophie to come with him.
He wanted her to come with him.
He wanted his friend to come with him.
He wanted the friend who he had met at university to come
with him.
VERB PATTERNS
Verbs that take ing forms:
Many ing forms can be replaced by nouns, such as those in the
objects of verbs these are often called gerunds.
Gerunds = A noun made from a verb by adding ing:
I enjoy reading (here reading is a noun)

CHAINING
Long chains of these verbs can be easily generated.
In this example, consider is followed by an ing form, then allow
is followed by a direct object+ infinitive and so is train:
We are considering allowing him to train Jeff to analyse the
data.
CHAINING
ing forms or to infinitives can be joined by: and or and
also.
We continue to practice kicking and catching balls.
