黄山绿卡

陈祖芬

①哈根达斯是顶级冰淇淋的象征。哈根达斯店的象征,是那纯白的椅子套和系在椅子套后的粉红大蝴蝶结。那纯白和粉红,叫人想起一含就化的香草冰淇淋和草莓冰淇淋。那厚重的布料,叫人感觉到一种坚挺的自信。

②走进黄山市的一个会场,好像一下跨进了哈根达斯的世界。满眼的白椅套和椅子背后的粉红蝴蝶结。只是这种蝴蝶结是粉红的薄纱。没有哈根达斯的强势,但是比哈根达斯更梦幻。

③比纯白和粉红更多的,是人。这个首届世界500强(黄山)国际论坛,显然来的人数超过了预计。会议就要开始了,服务人员还在扛着一把把座椅,扛着一个个粉红的梦幻进来。

④和我坐在一起的,一位是李总,福建人,在上海创业,早就做成上海人了,又到黄山做事。还有很多的“还有”。又一位是何总,从黑龙江到上海的。又从上海做到了国外。然后一掉头到黄山,在李总那C2C酒店买下一万平米,用来做亚健康研究。她说她去欧洲讲学,说起黑龙江,有的欧洲人不知道。她说黄山,都说知道。欧洲人又接着问:黑龙江离黄山有多远?

⑤想起一个越来越常用的词,叫做:资源组合。那何总原先学财会的,那李总原先学汽车制造的。只是他们比一般人更会把自我资源进行重新组合。他们称自己是新上海人。而我觉得,他们就要成为新黄山人了。黄山的资源,文化含量,名山秀水和一等的生态环境,这些资源一旦用新概念重新组合,那么黄山,一如市中心那条南宋时期开始兴建的屯溪老街那样,这座非常南宋,非常明清,非常徽派,非常古典的皖南山城,就突然与500强这个词连在了一起。

⑥在非常哈根达斯的会议厅里,中国人外国人杂坐在一起,最后两排也坐着不少老外,好像一个单位的人。我看到有美国苹果公司、英国世纪投资公司、IBM、花旗银行、德意志银行、杜邦公司……于是我又想起哈根达斯冰淇淋店那纯白椅背上的、坚挺的粉红蝴蝶结。500强是坚挺的,比起他们,黄山的经济就如这个会议厅里粉红纱的蝴蝶结,一种美好的梦幻,引人遐想。

⑦黄山人自己觉得,这个会“外向度不是很高”。不过,毕竟开始了。我包里装着一叠与会者给我的名片,外资、合资、港商、徽商。我一头雾水地看着这一堆名片,觉得好像拿着一堆黄山绿卡。

⑧黄山人自古就有攀岩而上的传统。有一种工作,是腰际系着绳索,在世界自然、世界文化双遗产的黄山的山崖山壁上拾捡垃圾。人称“放绳工”,我看可称为“黄山男”。有黄山男,就会有外向度。

⑨会议的论题之一是全球化企业的社会责任,演讲者是太平洋岛国论坛驻华贸易代表处首席代表艾伯翰先生和英国世纪投资集团总裁安托号·休欧沃。他们讲到市场决定一切,讲到创新是解决问题的根本方法,讲企业内部从最高层到最底层沟通……我听他们演讲,并未感到太多的冲击力,倒是最后一句,从老外口中讲出“我们的黄山”觉得新鲜而亲切。黄山成了“我们的黄山”,老外也就成了我们的老外。

⑩我去黄山闹市的屯溪老街,发现论坛上的老外们洒在老街的一条条小巷里了。一个老外要买三国里的刘、关、张。一个中国女孩问:“你喜欢这个?”老外用共鸣很强的男中音和洋腔洋调的汉语大声说:“喜欢!因为他们是三国的英雄。”

走下论坛的洋人,在屯溪老街寻觅三国英雄的洋人,他们的符号意义或许更强于实际意义。

《光明日报》8月报道:黄山深得“二老”厚爱,一是“老天爷”,一是“老祖宗”。黄山市今年上半年接待海内外游客678.9万人次。其中欧美市场游客接待量与去年同期相比增加52%。还有增加城市外向度的国际民俗文化节、国际旅游节、国际山地车比赛、徽文化国际研讨会,甚至这个世界500强国际论坛。我到黄山国际大酒店一住下,先翻看会议安排。细细密密的好几页。第7条,大会安排中英文同声传译,1频道为中文,2频道为英文。

而我想,1频道为徽文化,2频道为全球化。 (选自2007年10月30日《文汇报》,有改动)

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.

Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.

However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.

Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.
