LEARN THIS! Non-defining relative clauses

a. In non-defining relative clauses, we use who, which, where and whose, but we do not use that.

b. A non-defining relative clause: 

comes immediately (1) before / after a noun and gives us information about that noun.

adds extra information to the sentence; the sentence (2) makes sense / does not make sense without it.

(3) has / doesn't have a comma at the start. It has a comma or a full stop at the end.

I. Underline the Relative clauses and write Defining or Non-difining clauses.
