Conditional sentences are one of those sections of grammar that are used constantly in English: in conversations, letters, films, business correspondence. They help describe situations that depend on conditions: from simple real ones ("If the sun shines tomorrow, we'll go for a walk") to hypothetical and unreal ones ("If I were you..."). In this collection, you will find exercises for all types of Conditionals: Zero, First, Second, Third and mixed. We will practice the correct construction, choice of tenses, and also analyze typical mistakes. Each task is provided with answers so that you can test yourself and consolidate the material.
