Discuss the importance of the development of the English language and the influence of the various groups that invaded England: the Danes, Romans, Germans and French. Once people begin to see the rich history of the English language, they are more inclined to look on it favorably.
Talk about how there is no going back. English is now firmly entrenched as the international language and has established its importance.
Stress that to study in America, Canada, England, Australia or New Zealand, you have to be able to speak English. Having a degree from an English-speaking country gives people credibility.
Remind people that no matter if you are a pilot in Dubai or an air traffic controller in Yangon, you have to be able to speak English because it is the language of the air.
