Unit 9 : Should there be one world language that everyone speaks?

When we travel abroad that has a language we have never learned about, how can we communicate in that country?
When we meet foriegners how can we speak each other?
All of us know the awnser. We can use English and we can understand what they want to say or we can tell them what we want to say. The representative language can make us communicate if we had totally different languages. But this doesn't mean that there should be one world lanuguage.

The language is not only a language but also a window of its own culture. It contains a native culture and other languge cannot show that. The extinction of languge means also the extionction of the culture. It is not an overstatement.
All over the world, there are uncountable races, tribals, societies, etc. Then how can we unite the lanuage? Is it possible? Is there any government which has forciblness?
In conclusion there is no realistic.

For preservation of humanity values, we have to respect  the variety languages. The official language is what we need. Not "an languge."
