The document discusses the first conditional, which refers to possible future events that are likely or probable to happen. It has two parts: the if-clause uses a present tense verb, and the main clause uses a future tense verb or modal to indicate the result or consequence. Examples are provided like "If you don't disturb me, I will have finished in an hour" and it can also be used with words like "unless, as long as, as soon as, or in case" instead of just "if". The first conditional expresses a likely connection between a present situation and a probable future result.

FIRST CONDITIONAL

2. Just a quick
review:
• Conditional sentences express a connection between
two actions or states. One thing happens because of
another. These connections can be general, specific, likely,
unlikely, real or imagined.
• Zero conditionals
• Used to refer to habits, general truths, scientific facts and
instructions and rules. One thing happens and because of
this something else happens. In zero conditionals if and
when have the same meaning.

3. • It gives you the idea of a real
situation
• It also brings the idea of
something that is likely
(probable) to happen.
• We use the first conditional
when we talk about future
situations we believe are real
or possible

If you don’t disturb me, I will have finished in an hour.
If I haven’t come back by 8 o’clock, call the police.

6. Think about these situations and what’s likely to
happen:
If you find a wallet in the
street...
If you are given too
much change in a bank
or restaurant...
If the only parking space
available is a disabled
parking space...
If you know there are no
speed cameras on a
particular road...

7.  I'll leave as soon as the babysitter arrives.
 I don't want to stay in London unless I get a well-paid job.
 I'll give you a key in case I'm not at home.
 You can go to the party, as long as you're back by midnight.
 If I go to the shops, I’ll get some bread. (I might not go to the shops)
 When I go to the shops, I’ll get some bread. (I’m definitely going to the shops)
 If you’ve finished your homework by six, you can go out and play.
 When you’re having your party, please keep the noise down!
It is also common to use this
structure with unless, as long as,
as soon as or in case instead of if.
