You can improve your English skills by studying the reasoning and persuasive strategies that authors use in a variety of texts. You will need to expand your analytical vocabulary to do this well. I run a variety of classes in this areas, and the Language of Persuasion Series is an excellent resource. There is considerable online support for all articles in these workbooks, so that students can improve rapidly. These exercises help students apply the analytical vocabulary, terms and phrases modelled in the workbooks.
