This 30-question C1 grammar test covers substitution with one/ones, so/not, do so, that/those and the same, as well as ellipsis after auxiliaries, the infinitive marker to and so/neither. It suits advanced learners and exam candidates who want to sound natural and avoid repetition in speech and writing.
Use this test after teaching ellipsis and substitution, or as a diagnostic before exam writing tasks. It targets frequent C1 errors such as 'I don't think not', 'refused to do', 'brown one' with uncountable nouns and omitting 'been' in perfect ellipsis. As follow-up, ask students to rewrite a repetitive paragraph using the structures tested, or to role-play short dialogues using so/not, reply questions and short answers.
