The imperfect subjunctive

I have covered the imperfect subjunctive with my Year 13 students, but it is an area which still causes some difficulty. To support them I have put together the attached booklet. The imperfect subjunctive is something I want them to incorporate into their discursive language esp. in their individual research topics for the speaking exam and they also need to look out for it in the translation into Spanish in the summer exam. So, with this in mind the attached resources has emerged + I hope it will be of use to some other people.
