Question

Writeacher, I need your help to find exercises on the following grammar topics:

1) Defining and non-defining relative clauses.
(e.g. two sentences to combine ...)
2) Wish (+ simple past, past perfect, would + inf.)
3)Indirect speech (reporting verbs such as apologize, remind, offer, agree, promise, urge, ask, make etc.)
4) Verbs followed by the infinitive/gerund.

As you have a great teaching experience, I really hope you can help me. I'm also looking for a reading comprehension (with questions) to be included at the end of the grammar exercises.

Answer 1

Here are some webpages that have explanations and quizzes/exercises about relative clauses (which are also called adjective clauses):
http://teachro.publiccomputingservices.org/grammarpractice/clause/subadj.htm

http://grammar.ccc.commnet.edu/grammar/clauses.htm#independent
The quiz for these is at the bottom of this webpage.

(Essential & non-essential = restrictive & non-restrictive)

And the first three links here are perfect:
