Mixed Pronouns Practice - Advanced Exercises

This advanced exercise tests all pronoun types in complex sentences. You will work with double possessives like "a friend of mine" (not "a friend of me"), comparisons using "than" and "as" with the correct pronoun form, and two-person subjects where two or more pronouns appear together. You also need to spot common confusions between contractions and possessives: "they're" (they are) vs "their" (possessive adjective) vs "there" (place).

At B1 level, pronoun errors become harder to spot because they appear inside longer, more complex sentences. A sentence like "My colleague and I, who are older, should help them" tests two-person subjects, clauses, and object pronouns all at once. The key strategy is to break the sentence into smaller parts and test each pronoun separately. Remember that after "than" and "as," both subject and object pronouns are accepted in modern English, but formal writing prefers the subject form. These combined pronoun challenges appear frequently in Cambridge B1 Preliminary examinations.
