RELATIVE CLAUSES MADE SIMPLE.

Hello, everyone.
Although I'd say that the explanation in our books, (p195), is actually very good, it is pretty dense, so here's a simplified explanation.

As usual, I recommend www.perfect-english-grammar for theory and practice:

THEORY:

PRACTICE:

I hope you find them useful.
