English Grammar Easy 对比 Verbal Advantage - Level 9 的使用情况和统计数据

Verbal Advantage: Ten Easy Steps to a Powerful Vocabulary. A 10-step vocabulary program teaches 500 key words and 3,000 synonyms. Verbal Advantage provides a complete learning experience, with clear explanations of meanings, word histories, usages, pronunciation, and more. Far more than a cram session for a standardized test, the book is designed as a lifetime vocabulary builder, teaching a vocabulary shared by only the top percentage of Americans, with a proven method that helps the knowledge last. You will proceed through ten levels of vocabulary, each level more challenging than the last. For example, Level 1 contains words familiar to about 60 to 70 percent of adults—that is, words known to many high school graduates and most college graduates. By the end of Level 5 you will have raised your vocabulary to about the 75th percentile—the top quarter of all educated adults. By the end of Level 8 your vocabulary will have surpassed that of most executives and professionals, including those with advanced degrees. And when you complete the tenth and final level you will have progressed beyond 95 percent of the entire population. You will command an armory of words that only a handful of people in every thousand can match.
