Voyage of people from England play in important part in spreading the English lanuage.
At present,English is frequently spoken as an official or command language in many
countries,such as America,Singapore,Malaysia and some African countries.
All based on British English,the English spoken in these countries can be well to
understood by native English speakers.
But actually,these English have been gradually changing in accents,spellings,
expressions and the usage of vocabulary.
Because of this fact, you can make use of the differences to tell wich country
the foreigners of your block are from. For example,
if a boss fluently commands his driver,"Come up straight to my apartment by elevator
and take some gas for my trucks and cabs",instead of requesting,"Please come to my flat
by lift and take some pertrol for my lorries and taxis",you can recognize his American
identily,while the latter suggests that he is British.
