This document contains a worksheet with conditional sentences for an English language exercise. There are 12 conditional sentences presented with an "if clause" and corresponding "result clause". The sentences cover common conditional scenarios about boiling water, studying, freezing water, heating metal, traveling, eating, sleeping, drinking, saving money, and breaking a mirror. The worksheet is intended to practice using zero and first conditionals through a matching activity where students find the pairings of if and result clauses.
