　　10年前，阿里巴巴创始人马云到美国想募几百万美金却困难重重而今天，电子商务在中国商业舞台上扮演越来越重要的角色，仅淘宝网就有1.2亿用户。回首发展之路，以阿里巴巴为代表的电子商务走出了一条不同于西方的发展道路。在西方，企业的商务需求推动了网络和电子商务技术的进步，并促成电子商务概念的形成。在中国，网络和电子商务技术不断拉动企业的商务需求，进而引导了中国电子商务的应用与发展。

　　在当前金融危机面前，电子商务已成为全球中小企业的”过冬棉衣“。有关统计资料显示，在金融危机中，未运用电子商务的企业陷入困顿的比例达84.2％，而运用电子商务的企业陷入困顿的比例为16.8％，两者相差近5倍。为什么？对于一个企业来说，电子商务模式与传统交易相比，没有时间、地域限制，不受渠道制约，营销成本可降低55%，可降低16%总成本。金融危机之下买家更需要高效率的采购方法，在我国经济恢复的三五年时间内，电子商务将从一个非主流的商务平台逐渐变成一个主流的商务平台。

　　然而，电子商务发展的”绊脚石“使不少中小企业与消费者对电子商务心存忌惮。比如网上交易的安全问题，电子合同的法律问题，网络信用问题等等。所有电子商务服务商都在为搬除这些”绊脚石“而努力着。互联网高度透明化使新商业文明中的诚信变得越来越重要。如阿里巴巴平台上诚信指数高的商家生意一定好，并且还可以拿到无抵押贷款，而互联网的高度透明使不诚信的企业得到全球性的封杀。

　　相比国外的电子商务，中国仍处于起步阶段。电子商务潜力巨大，瓶颈还有待突破。目前，对商家进行认证及评级、国家及地方日益完善的电子商务立法、交易金第三方保管等措施都在促进着电子商务的健康发展。（选自《语文报》有删改）

Juanito Estrella has been a housekeeping manager on the US-based large passenger ship Carnival Spirit for 18 months and feels he has found the suitable position in his career(职业).He has always wanted to travel.“I guess I am a really restless spirit. I Iike traveling, so when the chance came,I jumped at it,”he says.

The chance came in the form of a newspaper advertisement for work on cruise ships(游船).At the time Estrella was the housekeeping manager at a Melbourne hotel.He applied and,after two interviews,a medical check and police clearance,the job was his.

Estrella is responsible(负责的)for the cleanliness of the ship,making sure that 160 crew work properly.“I enjoy it because there is no other work-you wake up each day in a different place and a different culture. It’s exciting when you go to the next country and you don’t understand the language,”he says.

Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries,and Estrella has learnt Spanish and a little Croatian.

But there is a downside .“You cannot get really drunk...because you have safety responsibilities to yourself and others,”he says.“You don’t really think about home.You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”

Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week.He warns the job is not for everybody. “You have to love being busy and be prepared to work every day—and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.
