　　美國的城市
　　美國的城市和全世界其他城市很相似。在每個(gè)國家，城市顯示著其文化價(jià)值。城市既包含了社會最好的方面：提供受教育、就業(yè)和娛樂機(jī)會，也包含了社會最糟糕的部分：暴力犯罪、種族沖突和貧困。美國城市和社會一樣正在發(fā)生變化。二戰(zhàn)后，美國大部分大城市的人口減少了，許多陽光地帶的城市人口卻增加了。在洛杉磯和休斯頓，人口都有所增長。人們從城市里搬進(jìn)搬出，這種現(xiàn)象反映出美國社會的價(jià)值正在發(fā)生變化。40年代末到50年代初，城市居民更加富足，生了更多的孩子，需要更多空間。他們從城里的公寓搬出去，到城邊的郊區(qū)購買自己的房子。這些地區(qū)沒有什么寫字樓或工廠。50年代美國人的夢想就是在郊區(qū)擁有一所自己的房子�，F(xiàn)在情況又變了，50年代時(shí)離開城市的人們的子女已經(jīng)長大成人，和他們的父輩不同，這些人想住在城里。一些人繼續(xù)搬到陽光地帶的城市，如德克薩斯州、佛羅里達(dá)州和加利福尼亞州等地，人口增長，城市變大。另一些人則遷往東北部和中西部更發(fā)達(dá)的城市，如波士頓、巴爾的摩和芝加哥。很多年輕的專業(yè)人員、醫(yī)生、律師和經(jīng)理人正在往城里搬。他們不愿意住在郊區(qū)而寧肯住在城里，是因?yàn)樗麄冊谀莾汗ぷ�，或者因�(yàn)閾?dān)心燃料短缺，再或者是喜歡城市帶來的刺激和機(jī)遇。一個(gè)新興階級——一個(gè)更富有、更活躍的階級正在遷入城市。
