Here is an worksheet on the the usage lapse that hadn’t have is, and how the simple hadn’t is the better choice for standard English prose. Having spend a lot of time trying to figure out the best ways to teach the use of auxiliary verbs like had, I appreciate this worksheet. At the same time, I don’t think I have ever heard any of my students here in New York City use the solecism of hadn’t have.
So, I’m not sure how useful this worksheet will be, or, therefore, why I wrote it. It is a full-page Microsoft Word Document with a short reading and five copy-editing/sentence-correction exercises; in other words, you can alter it to your needs. Finally, to give credit where it is so abundantly due, let me remind you that this worksheet, like every one of them under the Common Errors in English Usage banner, is based on material adapted from Paul Brians’ book of the same name, which he gives away at the Washington State University website.
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.
