In this worksheet, students can practise the form of the second conditional. The worksheet covers “could + infinitive” as well as the negative and question forms. In the first exercise, students students practise the form of the second conditional by using the verbs given in the correct form. The sentences share the same context, so students can contextualise the grammar. In the second exercise, students rewrite sentences in the first conditional into the second conditional, thus contrasting the use of these two grammar forms. There is an answer key.
