The document discusses different types of conditional sentences in English. It explains that zero conditionals are used to describe general truths and instructions, using the structure "if + present simple + present simple". First conditionals refer to possible future events and use the structure "if + present simple + will/going to". Commas are needed if the if-clause does not come first in the sentence. The different conditional structures are used to express different meanings around events that may or may not occur depending on certain conditions.

1. If the printer is about to print,
it will get jammed
If you have extra time,
you will be late.
If a toast falls,
it will land on the buttered side

2. When the connector is IF,
we don´t speak of a future time clause
If introduces CONDITIONAL sentences
