Native English Speaker

Many think the best way to make foreigners understand is to be chatty and informal. | Equally, any native English speaker wanting to deal with these new high achievers needs to know how to talk without baffling them. | Because so many English-speakers today are monoglots, they have little idea how difficult it is to master another language. | Anyone wanting to get to the top of international business, medicine or academia (but possibly not sport) needs to be able to speak English to a pretty high level. | This may seem friendly but, as it probably involves using colloquial expressions ("shall we crack on then?"), it makes comprehension harder.
