OK, finally this afternoon (and once again from Paul Brians’ magisterial usage manual, Common Errors in English Usage, which he very generously gives away in a variety of places), here is a worksheet on differentiating the adverbs heavily and strongly. This is a one-page worksheet with ten modified cloze exercises to supply students with structured practice in using these two words.
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.
