Is this a good thing,or a bad thing?Should we celebrate① the fact that more and more of us can communicate②,using a common language,across countries and cultures?Or should we worry about the dangers of “mono-culturalism”,a world in which we all speak the same language,eat the same food and listen to the same music?  Does it matter if an increasing number of people speak the same language?I would have thought the other way around(相反) although I have never accepted the argument③ that if only we all understood each other better,there would be fewer wars.Ask the people of India(where many of them speak at least some English) and Pakistan(the same situation with India)...
