Passage　1
Tourism　wasn't　as　important　as　it　is　today.　In　the　past,　only　people　with　a　good　deal　of　money　could　travel　on　holidays　to　other　countries.　More　people　travel　today　than　in　the　past　because　there　is　a　growing　middle　class　in　many　parts　of　the　world,　that　is　to　say,　people　now　have　more　money　for　travel.　Special　air　plane　fares　for　tourists　make　travel　less　expensive　and　more　attractive　than　ever　before.
One　person　doesn't　travel　for　the　same　reason　as　another.　But　most　people　enjoy　seeing　countries　that　are　different　from　their　own.　They　also　like　to　meet　new　people　and　new　food.
