Pronunciation

The most difficult problems occured during teaching pronunciation were the students  
could not say some words correctly: eg: "thank you", "steak", "butcher", "failure", "preface", "fiancee", "Alburquerque", "nightiangle" etc.

If you could not say it correctly please learn from Oxford Genie Dictionary or other suitable dictionaries which has British English accent that can help you a lot.

I usually found it when teaching "The step of looking up a dictionary" topic.
