After watching this awesome video, I think David is right, English should be teach as a global English, and the listening comprehension for example, must be understood as recommendable for English learners keep in touch through different accents, not speaking but listening to. A good example is the broadcast radios, one of the most interesting tip is listen to them.We should contact with different English standards, besides if we have the opportunity to travel to a foreign country, for instance in England we are facing the problem to find out different kind accents, in addition we are non-native Learners, even we have decided to learn British or American standard, sometimes we mix with both, the most important thing is practising a real English.
