Here is a learning support on using that and which in declarative sentences from Paul Brians’ book, Common Errors in English Usage, which he has helpfully and generously published on the Washington State University website.
I confess that I don’t find this short passage particularly helpful in using these two words, bound up as they are with restrictive and nonrestrictive clauses in sentences (a lesson on which is forthcoming on this blog). That said, this document, like several others of its type, contains only a couple of short paragraphs. So, as a Microsoft Word document with a lot of open space, it is yours to do with as you wish or need.
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.
