I think this doesn't regard modals and their past and present uses, but rather the putative should:<br/><br/><i> I <b>am taking</b> a book with me in case I <b><u>should </u>get</b> bored.</i><br/><br/>1) Is the past tense version still OK with 'should'?<br/><br/><br/><br/><i>I <b>took</b> a book with me in case I <b><u>should</u> get</b> bored.</i><br/><br/>Thanks
