1. WHAT IS IT

   • Conditionals are used to speculate on what might happen, what may have happened and what we wish to happen. In English, most of the sentences that use conditional tense contain the word "if". Many of the conditional constructs are used in English sentences including verbs in the past. This use is called "the unreal past" because we use a past tense but we are not referring to something that has actually happened. There are five main ways to build conditional sentences in English. In all cases they consist of a proposal or clause "if" and a main proposition. In many negative conditional sentences there is an alternative equivalent construction using "unless" rather than "if".
