Adapted from Paul Brians’ book Common Errors in English Usage (to which he allows no-cost access at his Washington State University web page), here is a worksheet on the proper use of the auxiliary verbs may and might. This is full-page worksheet with a reading of four short paragraphs, five modified cloze exercises, and an imperative for students to compose their own sentences, from subject to period, using one of these auxiliary verbs.
Incidentally, I have struggled over time to figure out a way to teach the use of auxiliary and modal verbs. They present a tricky area of usage. I’d like to think this worksheet, informed by Professor Brians’ crystal clear style, goes some distance to clearing up the use of these two words.
