This book is intended to support people who need to improve their basic command of written and spoken English, but who don’t have much time to spend working on it. The book focuses on the most common problems Swedish speakers have in English and offers a quick fix and also a simple explanation, without going too far into grammar terms. This makes it especially useful for teachers who need to be able to teach English, but feel unsure about their use of the language. There is a companion website with an electronic version of the text and sound examples for the pronunciation chapters, as well as a self-diagnosis test you can use to see what you need to work on.
