Unless, even if, provided, as long as, etc.: Other expressions in conditionals

This exercise helps you master alternative expressions commonly used in conditional sentences. Instead of only relying on if, you'll practice using unless, even if, provided, as long as, in case, and other similar phrases. These structures allow you to communicate conditions, exceptions, and contrasts with greater clarity and fluency. Ideal for upper-intermediate learners aiming to enhance their control of complex sentence forms in both formal and informal contexts.
