Adapted from the pages of Paul Brians’ superlative manual Common Errors in English Usage (which, as I like to remind readers of this blog, he allows free and unfettered access to at his Washington State University web page), here is use of the verb mislead and its past tense, misled. This is a full-page document with a four-sentence reading and ten modified cloze exercises. The principal usage problem this worksheet addresses (as you can see, you have both the present tense and the past tense of the verb mislead here) is making sure one is using properly the present tense (mislead), the past tense (misled) and the past participle (also misled).
