I need some some exercises about defining and non definifining clauses but relative clauses plus prepositions. Sentences with at with, to whom, by which etc.... For instance
1- Th"That lady is my English teacher. I was talking to her just now."
The lady Who I was TALKING TO is my teacherWhere can I find them?
Ihave gone through different websites on internet and I have some exercises, but I need more. My students need them for an exam.
