Book excerpt: THE KNOWLEDGE YOU NEED TO BE A GRAMMAR GURU. How you speak and write can say a lot about you. Grammar makes a lasting impression, but learning it can seem like a never-ending parade of complicated and contradictory rules! That’s why we at The Princeton Review created Grammar Smart—instead of boring you with countless rules and confusing grammatical terms, this book takes a fun approach to showing the logic behind each correct sentence. This updated fourth edition of Grammar Smart brings you: • In-depth reviews of the basic parts of speech • Tips on how to avoid misplaced modifiers and dangling participles • A glossary of key grammar terms • Quick quizzes throughout the book to help you check your progress • Detailed sentence diagrams to help you identify word classes • Comprehensive summaries of each major grammar topic
