This, like most of Warriner's books from public schools go back to Elementary, Jr.High, High School, and University studies. Very good and very straightforward composition and grammar discussion. I never thought I'd be TEACHING English one day. It wasn't my plan. But even though I studied sciences I ended up living overseas and now...I teach English! When I last returned home I was able to get some English teachers at public school to part with some of them and I use them in my lessons now. If one really reads them, you can see what English has to offer and how amazing language is. Cheers.
