For example, we can predict that "If my brother crashes the car tonight, my mother will be furi ous.” Type 2 conditionalType 2 conditional refers to present and future situations. It is used to talk about unreal—impossible, improbable or imaginary—situations. It refers to an unlikely or hypothetical condition and its probable result.Type 2 conditional consists of two clauses, one with if + subject + simple past verb and the second with subject + would + verb, as in, “I would buy a big house if I had a million dollars.”Step 3 Doing exercisesThen ask students to finish these exercises.
