三峡工程是治理和开发长江的关键性骨干工程，建成后水库正常蓄水位175米，总库容393亿立方米，具有防洪、发电、航运等巨大的综合效益。工程分为大坝、电站、通航建筑物等几个主要部分。大坝全长2309米，坝顶高185米。电站设有左、右两组共26台单机额定容量为70万千瓦的大型水轮发电机组。通航建筑物包括双线五级船闸和垂直升船机，分别可通过万吨级船队和3000吨级客货轮。2003年和2005年，国务院三峡工程建设委员会又先后批准建设电源电站和右岸地下电站，三峡工程总装机容量达到2250万千瓦，年发电量约880亿千瓦时，主要供应华中和华东地区。 其工程建设分为三个阶段：第一阶段从1993年至1997年，完成了大江截流。第二阶段从1998年至2003年，先后建成主坝、左岸电站和永久船闸，按期实现水库初期蓄水、首批6台机组发电和通航三大目标。第三阶段从2004年至2009年，以实现工程基本完工和全面运营为标志。2006年，大坝全线达到185米设计高程，水库蓄水至156米水位目标。 截至2005年底，中国长江三峡工程开发总公司累计筹集建设资金1220.31亿元(含移民工程)，包括：国家拨入资本金623.22亿元，其中三峡工程建设基金621.38亿元；债务性资金413.97亿元(主要是国家开发银行贷款和三峡企业债券)；发电及出售机组收入等183.12亿元。三峡工程累计完成动态投资642亿元(不含移民工程)，完成静态投资425.85亿元，占静态总投资500.9亿元的85%。至2009年三峡工程基本竣工(除右岸地下电站和垂直升船机外)，尚需投资约140亿元，静态总投资可控制在概算确定的500.9亿元内，预计动态总投资为780多亿元，比1994年预测总投资减少350多亿元。 以下说法正确的是( )。

Though it is a mere I to 3 percent of the population, the upper class possesses at least 25 percent of the nation’s wealth. This class has two segments: upper-upper and lower-upper. Basically, the upper-upper class is the "old rich"--families that have been wealthy for several generations--an aristocracy of birth and wealth. Their names are in the Social Register, a listing of acceptable members of high society. A few are known across the nation, such as the Rockefellers, Roosevelts, and Vanderbilts. Most are not visible to the public. They live in grand seclusion, drawing their income from the investment of their inherited wealth. In contrast, the lower-upper class is the "new rich". Although they may be wealthier than some of the old rich, the new rich have hustled to make their money like everybody else beneath their class. Thus their prestige is generally lower than that of the old rich, who have not found it necessary to lift a finger to make their money, and who tend to thumb their noses at the new rich. However its wealth is acquired, the upper class is very, very rich. Thy have enough money and leisure time to cultivate an interest in the arts and to collect rare books, paintings, and sculpture. They generally live in exclusive areas, belong to exclusive social clubs, rub elbows with each other, and marry their own kind—all of which keeps them so aloof from the masses that they have been called out-of-sight class (Fussel, 1983). More than any other class, they tend to be conscious of being members of a class. They also command an enormous amount of power and influence here and aboard, as they hold many top government positions, run the Council on Foreign Relations, and control multinational corporations. Their actions affect the lives of millions.
