Conditional Sentences
First Conditional: real possibility
In order to explain the Conditional Sentences, we will think of Tom.

Tom has real problems because his ship sank and he arrived at a tiny island. On the island there is only grass and a palm tree.

It is always sunny there but he has no food nor water. What can he do?
Tom finds two new problems:

We use WILL + INFINITIVE to talk about the
possible future
result. The important thing about the first conditional is that there is a
real possibility
that the condition will happen.
He thinks:
“If I stay on the island, I will get burned”
He thinks:
“If I swim, the sharks will eat me”

1. There is a fire on the island!
2. There are sharks in the sea!
Notice that we are thinking about a future condition. Tom is not swimming right now. But he can see the sharks. We use the
present simple
tense to talk about the possible future condition.
Second Conditional: Improbable
if + Present Simple + Will INFINITIVE
“If I
stay
on the island, I
will

get
burned”
“If I
swim,
the sharks
will eat
me"
if + Past Simple + Would INFINITIVE
Third Conditional: Impossible / Past
if + Past Perfect + Would Have PARTICIPLE

He starts thinking of unreal situations:
He hoped a boat appeared
He thinks:
“If I had wings, I would fly home”
He thinks
“If I had a boat, I would sail home”
The second conditional is like the first conditional. We are still thinking about the future; but there is
not a real possibility
that this condition will happen. It is like a
dream.
It's not very real, but it's still possible.
We use the
past simple
tense to talk about the future condition. We use
WOULD + INFINITIVE
to talk about the future result.
“If I
could
fly, I
would fly
home”
“If I
a boat, I
would sail
home”
After some time...
A friend of him, Tim, is flying in his helicopter ...
when he suddenly sees Tom’s red shirt!
Tim saves Tom.
Once in the helicopter Tom says:
“If I had not worn a red shirt, you would not have seen me”
“If you had decided to stay home today, I would have died!”
“If I
not
worn
a red shirt, you
would
not
have seen
me”
“If you
to stay home today, I
would have

died
!”
The first conditional and second conditionals talk about the future. With the third conditional we talk about the
past.
We talk about a condition in the past that
did not happen
. That is why there is
no possibility
for this condition. The third conditional is also like a dream, but with no possibility of the dream coming true.
Notice that we are thinking about an i
mpossible past condition
. We use the
past perfect
tense to talk about the impossible past condition. We use
WOULD HAVE + past participle
to talk about the impossible past result. The important thing about the third conditional is that both the condition and result are impossible now.
