An article I read at the BBC today discussed the more difficult role of native speakers of English in a world of expanding non-native speakers, particularly in the workplace. It found that native speakers, when communicating with non-native speakers, need to speak more slowly, avoid slang and idiomatic expressions and also expand their contractions. In the latter case (obviously), it's becomes it is, don't becomes do not and so forth.

Well, good to get that learnt! I look forward to more in the vein of, Studies Show That Water Quenches Thirst, and similar space-fillers.
