Throughout their history， Americans have beenpeopleonthemove.The early immigrants had to travel to get to the New World. Once they arrived， they settled along the East Coast.But they weren' t content to stay there. Explorers and traders journeyed to the unknown western territories. Later， settlers moved west to develop these new areas. As a result of this westward mi- gration， Americans eventually occupied the whole continent-from the Atlantic to the Pacif- ic. Even today， Americans seem unable to stay put. Research says that the average American moves every five years.

Besides their habit of changing addresses， Americans are used to traveling. Most Ameri- cans prefer to travel within their nation's bor- ders. Why？ For one thing， it' s cheaper than trav- eling abroad， and there' s no language problem But besides that. the vast American territory of- fers numerous tourist attractions.

People all over the worldenjoy going abroad to travel. And no matterwhere they live， people enjoy visiting scenicspots in their own country. But being on the go

Jmakes Americans what they are： people on themove. In America. almost everybody is a touristsometime.

縱觀整個歷史，美國人一直是個遷移的民族。早期的移民者必須長途跋涉才能抵達新大陸，他們一到達就沿著東岸定居，但卻不滿于長居那地，冒險家和商人旅行至未知的西部地區(qū)。稍后，移民者也向西遷移去開發(fā)這些新地區(qū)。由于向西遷移，美國人最后占據(jù)了整塊新大陸——從大西洋到太平洋。即使到今天，美國人似乎仍然無法在一地久居。根據(jù)研究，美國人平均每五年要搬一次家。

除了搬家的習慣以外，美國人也很習慣旅行。大部分美國人比較喜歡在國內旅游，為什么呢？其中一個原因是，國內旅游比國外旅游便宜，也沒有語言不通的問題。但除此原因以外，占地極廣的美國國土提供了許多能吸引游客的地點。愛好大自然的人可以到海灘、山上、峽谷、湖泊和很多大自然奇景地區(qū)游覽。大城市也提供給游客們很多都市形態(tài)的娛樂?，F(xiàn)代高速公路、鐵路和飛機使得在美國旅行很容易。

很多美國假期非常特別，和參與此種假期的人一樣特別。全家出游時通常會將孩子考慮在內，有愈來愈多“適合全家出游”的度假地點為孩子提供特別的活動。對歷史有興趣的人會找一些著名的歷史遺跡和博物館。有環(huán)保意識的人喜歡“環(huán)保假期”，這樣的旅行使他們能近距離觀察動植物，并且不會擾亂了大自然敏感的生態(tài)平衡。有些人覺得海上旅游能使心情放松并感到清爽，有些人則到水邊釣魚、滑水或泛舟。膽子大的人到亞洲和非洲去探險狩獵作長途旅行，享受一輩子難得一次的刺激。

美國人不是世界上唯一愛旅行的人。國際企業(yè)、大眾傳播與噴射機創(chuàng)造了一個環(huán)游世界者的世紀。全世界的人都喜歡到海外旅游，不管住在哪里，人們都喜歡去造訪自己國家內風景優(yōu)美的地區(qū)。不過好動的本性使美國人變成今天的模樣：成為愛遷移的人。在美國，幾乎每個人都有旅游的經驗。
