Every country tends to accept its own way of life as being the normal one and to praise or
criticize others,as they are similar to or different from it.And unfortunately,our picture of the
people and the way of life of other countries is often a distorted (扭曲的) one.
Here is a great argument in favor of foreign travel and learning foreign languages.It is only
by traveling in a country and getting to know its inhabitants and their language that one can
find out what a country and its people are really like.And how different the knowledge one
gains this way frequently turns out to be from the secondhand information gathered from
other sources! How often we find that the foreigners whom we thought to be such different
people from ourselves are 
not very different at all!
Differences between peoples do,of course,exist and,one hopes,will always continue to
do so.The world will be a dull place indeed when all the different nationalities behave exactly
alike,and some people might say that we are rapidly approaching this state of affairs.With the
much greater rapidity (快速) and ease of travel,there might seem to be some truth in this at
least as far as Europe is concerned.However this may be,at least the greater ease of travel
today has revealed (展示) to more people than ever before that the Englishman or Frenchman
or German is not:some different kind of animal from themselves.
