This document discusses conditional sentences in English. It explains that there are three types of conditional sentences: ones referring to universal truths, ones referring to possible present or future situations, and ones referring to hypothetical past situations. The types are distinguished by the tense used in the if-clause and main clause, such as using present tense for universal truths, present/future tenses for possible present/future situations, and past tense for hypothetical past situations. Examples are provided for each type.
