If you can use it (and I remain skeptical of the utility of these materials, whose manufacture I nearly abandoned several times), here is a worksheet on the verb practice when used with a gerund. I practice deprecating worksheets which are of dubious value.
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.
