Here is a learning support on five kinds of sentences. I grabbed this from Sylvan Barnet and Marcia Stubbs’ Barnet and Stubbs Practical Guide to Writing with Readings, Seventh Edition (New York: Harper Collins, 1995). I used an earlier edition of this book for the very first college course I took in the spring of 1990. When I mentioned my admiration for the utility and ease of use of the book, a friend of mine thoughtfully made me a gift of the edition cited above.
Anyway, this learning support doesn’t deal with the four kinds of sentences, i.e. declarative, interrogative, imperative, and exclamatory, for which I am currently preparing learning supports which will appear here in the near future. This document deals with syntactical structures, to wit, the simple, compound, complex, and complex-compound sentences, as well as the sentence fragment. It’s one page, so it’s simple but (I hope) helpful because of that simplicity.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
