Common Errors in English Usage: Let Alone

From Paul Brian’s book Common Errors in English Usage, here is a worksheet on the use of the conjunction Let alone, as in “I can’t finish this do-now exercise, let alone write a research paper.” There are no structured exercises on this worksheet, which calls upon students simply to compose sentences in which they properly use the conjunction let alone–as well as much less and never mind, two similar conjunctions.
