400 Must-Have Words for the TOEFL® will help you improve your score on the TOEFL test. In particular, this book will build your TOEFL vocabulary for the new Internet-based TOEFL of 2005. 

This book is designed for ease of use as a self-study guide. Its chapters were written for easy completion in one sitting—about 25 minutes. 400 Must-Have Words is also highly effective in the TOEFL-prep classroom. 

Each chapter begins with a list of 10 target words. These words are defined and used in sample sentences. Usage tips are given for many words, as are any commonly used parts of speech related to the target word.

Following these definitions, the words are practiced in three exercises. TOEFL Prep I and TOEFL Prep II give straightforward practice in a variety of easy exercise styles. The last exercise, TOEFL Success, includes a TOEFL style reading followed by one or two authentic TOEFL-style questions. Most TOEFL Success readings incorporate all 10 target words, and most also include an additional bonus structure. Each chapter ends with an answer key so you can check your work. 

As an extra feature, this book includes a special front section called “Six Quick Hints for Success on the TOEFL®.” These hints give general test-taking advice for TOEFL success. 

This book was written by ELT professionals who help prepare students for the TOEFL test. Their selection of words for this book was based on extensive experience with the TOEFL test, information about the corpus (body of words) that is used in creating the actual TOEFL test, and TOEFL materials published by ETS, the creators of the TOEFL test.
