The ESL Guide to American Business English is filled with errors and is not geared to the sophisticated second language learners who are the expected consumers for a book of this nature. For example, the explanation of when an -s is needed as an ending for present tense verbs states that the -s should be added when the subject of the sentence is a noun. Yesterday I read this explanation to one of my ESL students, whose response was, "What about 'everyone' or 'no one'?" Exactly. There is no mention of pronouns. Students using this book to study on their own might find it confusing -- at best.The examples provided to illustrate this poorly explained "rule" have the words "secretary" and "stenographer" as subjects -- hardly current. I could go on and provide a long list of what's wrong with this book, but I've given it enough time.I regret having ordered this book and would not recommend it to anyone. It's worse than useless.
