This document provides information and examples to help with key word transformation exercises for the Cambridge English: First exam. It begins by outlining the steps to complete keyword transformations and the types of grammatical structures that may be required, including passive forms, conditionals, reported speech, phrasal verbs, and more. Various chapters then provide lists and examples of different grammatical structures and vocabulary that commonly appear in keyword transformations, such as speculative language, time expressions, conditionals, verb patterns, idioms, and set phrases. Practice exercises are included at the end to help students apply what they've learned.
