Here is a worksheet you can use in your French II classes or as a review in French III for quelque chose/rien;quelqu'un/personne and encore/ne plus.Students have trouble going from present tense to passe compose. All three of these points are on Le Grand Concours for French II. The page provides a detailed explanation with examples, then practice sentences in present and passe compose. Since this is a Word document, you can copy and paste it into a power point to help you explain/review to students. My students seemed to understand the concept better after this sheet.
