This is the pdf version of a real textbook about German-English language interference (188 pages). It comprises an extensive introduction to the topic, 56 innovative worksheets, and a humorous section. The worksheets appear on the left-hand page with the solutions on the opposite page, which should prove very convenient for teachers and ESL students.
The book focusses on two different types of interference:
On the one hand there are innumerable cases of external interference, i.e. disruptions because of discrepancies between the German and the English language. For example, the German expression ein Beispiel für induces most beginners to assume that the English preposition is the same, thus using an example for instead of an example of.
On the other hand there are all kinds of internal interference, i.e. disruptions within the English language. A case in point is the following group of words, which are pronounced differently although they might seem to rhyme: cough - dough - plough - rough - though - through – tough.
A comprehensive index complements the worksheets.
The textbook reflects my experience as an English teacher at a Gymnasium in northwest Germany.
