In the form of a training book, Let's Write English helps the readers build some accepted habits and conventions associated with compositions, by methodical practice in analyzing and then using the written forms of English.
Wishon and Burks, guys you are smoking!! One of my all-time favorite books. I find this a great help in developing the common sense needed when dealing with written English (be it writing or reading).
First, this humbly titled book will help you befriend yourself with sentences, paragraphs, combining sentences into paragraphs, paragraphs into compositions, and such.
Then, in the second part, this book will help you deal with the tough guys (narration, description, explanation and argumentation), even when they are being complex.
One of those [very rare] books where I fail to find any crap, however little. Definitely deserves no less than five stars (*****) from just anybody.
