I made this worksheet to organize the use of the modals Should and Ought to in the Past and Present. It focuses more on the past aspect and also includes to questions that force the answer to be constructed in the Passive Voice. If there are any recommendations as to how it could be better, please leave a comment. Almost forgot, the first page is actually the second and the second the first. It should be rather obvious what order to put them in. Cheers to all!
