“旅行是偏见、偏执和狭隘的死敌。而这正是我们很多人迫切需要的。对人对事广阔、全面、仁慈的看法,一生呆在地球某一个小角落是得不到的。” ——马克.吐温。"Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime."
