绝版的周庄  王剑冰

你可以说不算太美,你是以自然朴实动人的。粗布的灰色上衣,白色的裙裾,缀以些许红色白色的小花及绿色的柳枝。清凌的流水柔成你的肌肤,双桥的钥匙恰到好处地挂在腰间,最紧要的还在于眼睛的窗子,仲春时节半开半闭,掩不住招人的妩媚。仍是明代的晨阳吧。斜斜地照在你的肩头,将你半晦半明地写意出来。

我真的不知道,你在那里等我,等我好久好久。我今天才来,我来晚了,以致使你这样沧桑。而你依然很美,周身透着迷人的韵致。真的,你还是那样纯秀、古典。只是不再含羞,大方地看着每一位来人。周庄,我呼唤着你的名字,呼唤好久了,却不知你在这里。周庄,叫着你的名字,你比我想象的还要动人。我真想揽你入怀。只是扑向你的人太多太多,你有些猝不及防,你本来已习惯的清静与孤寂被打破了。我看得出来,你已经有些厌倦与无奈。周庄,我来晚了。

有人说,周庄是以苏州的毁灭为代价的。眼前即刻闪现出古苏州的模样。是的,苏州脱掉了罗衫长褂,苏州现代得多了。尽管手里还拿着丝绣的团扇,已远不是躲在深闺的旧模样。这样,周庄这位江南的古典秀女便名播四海了。然而,霓虹闪烁的舞厅和酒楼正在周庄四周崛起,周庄的操守能持久吗?

参加“富贵茶庄”的奠基仪式。颇负盛名的富贵企业和颇负盛名的周庄联姻。而周庄的代表人物沈万三也是名富,真是巧合。代表富贵茶庄讲话的,是一位长发飘逸的女郎,周庄的首席则是位短发女子,又是巧合。富贵、茶、周庄、女子,几个字词在濛濛春雨中格外亮丽。回头望去,白岘湖正闪着粼粼波光。

想起台湾作家三毛,三毛爱浪游,三毛的足迹布遍全世界,三毛的长发沾得什么风都有。三毛一来到周庄就哭了,三毛搂着周庄像搂着久别的祖母。三毛心里其实很孤独。三毛没日没夜地跟周庄唠叨,吃着周庄做的小吃。三毛说,我还会来的,我一定会来的。三毛是哭着离去的,三毛离去时最后亲了亲黄黄的油菜花,那是周庄递给她的黄手帕。周庄的遗憾在于没让三毛久久留下,三毛一离开周庄便陷入了更大的孤独,终于把自己交给了一双袜子。三毛临死时还念叨了一声周庄。周庄知道,周庄总这么说。

入夜,乘一只小船,让桨轻轻划拨。时间刚过九点,周庄就早早睡了,是从没有电的明清时代养成的习惯?没有喧闹的声音,没有电视的声音,没有狗吠的声音。

周庄睡在水上。水便是周庄的床。床很柔软,有时轻微地晃荡两下,那是周庄变换了一下姿势。周庄睡得很沉实。一只只船儿,是周庄摆放的鞋子。鞋子多半旧了,沾满了岁月的征尘。我为周庄守夜,守夜的还有桥头一株灿然的樱花。这花原本不是周庄的,如同我。我知道,打着鼾息的周庄,民族味儿很浓。

忽就闻到了一股股沁心润肺的芳香。幽幽长长的经过斜风细雨的过滤,纯净而湿润。这是油菜花。早上来时,一片一片的黄花浓浓地包裹了古老的周庄。远远望去,色彩的反差那般强烈。现在这种香气正氤氲着周庄的梦境,那梦必也是有颜色的。

坐在桥上,我就这么定定地看着周庄,从一块石板、一株小树、一只灯笼,到一幢老屋、一道流水。这么看着的时候,就慢慢沉入进去,感到时间的走动。感到水巷深处,哪家屋门开启,走出一位苍髯老者或纤秀女子,那是沈万三还是迷楼的阿金姑娘?周庄的夜,太容易让人生出幻觉。

答:

2.小题2:第三段开头说,“周庄是以苏州的毁灭为代价的”,这里“毁灭”二字表达了作者怎样的感情?

The Happiest Cities On Earth

If you’re looking for a cheery destination for your next vacation, consider these four spots and get ready to take notes on how to really live the good life.

Singapore

With one of the highest population densities(密度)in the world and residents known for being workaholics, it’s hard to imagine the city-state of Singapore having one of the happiest populations on earth. And yet in a recent survey, 95% of them said they were either very happy or quite happy.

They give their city high marks for cleanliness and safety—subways are pristine (洁净的) and unfailingly arrive on time, and police are seen as helpful and good at their jobs. What’s more, they feel they can count on their neighbours—all 5.1 million of them.

Arhus, Denmark

The residents of Arhus cheerfully part with 68% of their income in taxes, knowing that in return they will be guaranteed free healthcare, free daycare, and a top-notch (第一流的) education for their children.

An energetic city of 300,000 with a lively cultural scene and a diverse number of religions represented, the sense of equality (the range in incomes is narrow), as well as easy access to the nearby sea and surrounding countryside, make Arhus seem more like a small town.

San Luis Obispo, CA

According to a 2008 Gallup-Healthways study, people who live in San Luis Obispo are more likely than residents of other U.S. cities to smile and experience joy and are less likely to experience pain or depression. About 64,000 of the 260,000 people in the greater metropolitan area (都市区), located halfway between Los Angeles and San Francisco, volunteer at over 11,000 non-profit organizations.

Few journeys to work are longer than 10 minutes (one reason its members rank in the upper third for job satisfaction), so “it’s easy to be involved,” resident Pierre Rademaker said. Business signs are unobtrusive (不显眼的) by law, fewer than 11% of residents smoke—the lower rate in the U.S.—there are lots of bike lanes, and the city’s plaza draws crowds of people for free concerts on summer Fridays. What’s not to love?

Monterrey, Mexico

The people of Monterrey don’t enjoy high household incomes or access to good healthcare. Instead, there’s a profound sense of gratitude for the new political freedom enjoyed since the oppressive Institutional Revolutionary Party lost power in 2000—the first time in nearly a century—as well as an emphasis on social life over work.

Another reason Monterrey residents may be so happy is their faith in God and family, and their ability to tough it out through bad times.

“We laugh at sickness, poverty and even death,” says Basanez, a political scientist who lives in Monterrey. “We even have a holiday to celebrate death. November 2, the Day of the Dead, is one of the biggest holidays of the year.”

小题1:According to the passage, what do the residents in the four cities have in common?

A.All the residents can make great fortunes by working hard.

B.The residents there are mostly educators.

C.All the residents enjoy enough material wealth.

D.The majority of the residents are satisfied with their current life.小题2:According to the passage, we can infer that _______.

A.the people of Singapore expect their neighbours to come to their help when necessary

B.the people of Monterrey even observe one’s death on a special day of a year

C.the residents of Arhus happily pay 68% of their income for their children’s education fee

D.the people who live in San Luis Obispo have job satisfaction because they can enjoy good working conditions小题3:According to the passage which of the following statements is NOT TRUE?

A.The people of Monterrey didn’t enjoy political freedom until 2000.

B.The residents in Singapore feel happy because of its low population density.

C.The people of San Luis Obispo can enjoy free concerts in summer.

D.Arhus is handy to the seaside and countryside.小题4:What can we learn from the underlined part “the sense of equality”?

A.The residents of Arhus have no racial discrimination.

B.Arhus is considered as a family sharing everything with each other.

C.There is no wide gap between the rich and the poor in Arhus.

D.The residents of Arhus can depend on their neighbours to help.
