Officials in the Midwestern U. S. town of Joplin, Missouri, say the death from Sundays’ big tornado reaches 116 and that search efforts continue for possible survivors trapped in rubble (碎石). Search and rescue teams are conducting their third sweep through the nearly 10 kilometer – long and one – kilometer wide area of destruction left by the tornado. They are working as quickly as possible while weather conditions remain relatively stable. More storms are forecast for the erea.

Joplin Fire Chief Mitch Randles said there are areas with large piles of rubble that might hold survivors. “We are still finding individuals. We did rescue seven individuals from underneath rubble yesterday and , of course, we are also finding dead folks as well.” Said mre folks and that is why we are doing these searches. We want to make every opportunity that we can to find everybody that is in the rubble and that has survived to this point.”

Randles said the current sweep involves a slower pace that previous searches and that he plans a fourth search, possibly on Wednesday, using specially trained dogs. “We are searching every structure that has been damaged or destroyed in a more in-depth manner, “he said.” I have dogs and dog handlers coming from all over the country do help us in that effort.”

Joplin City Manager Mark Rohr said the Red Cross and other volunteer organizations are helping people who were left homeless by the tornado and that the Federal Emergency Management Agency, or FEMA, is on hand to help. “Joplin is a great city. We have suffered a great loss, “said Rohr.” We will recover and we will recover strongly and we have a lot of help and a lot of volunteers to make that easier.”

The tornado that struck Joplin was classified by the Natioonal Weather Service as an F – 4, with winds of more than 300 kilometers per hour. It lasted only  20 minutes, but it killed more that 100 people, injured more than 400 others, and destroyed or heavily damaged some 2,000 homes, businesses, churches and a hospital. Authorities have registered more than 1,700 calls about missing people and they hope to resolve most of those cases soon, as victims are identified and survivors come forth and reunite with loved ones.

This was the worst tornado to strike the United States in 60 years. It was the latest in a wave of violent storms that have swept Midwestern and southern states in recent weeks, leaving more than 300 people dead an causing more than $2 billion dollars in damage.

北京奥运瘦身后节省几十亿元                    场馆建设采购全透明  “奥运场馆的地点,我们原则上不会改变。”北京市发改委官员、北京奥运经济办公室杨兆科在昨天举行的北京2004年奥运经济论坛上表示,北京奥运场馆将在原来的基础上进行微调,整个瘦身计划估计可以节省几十亿元。                  马术比赛可能转到香港  杨兆科表示,从目前来看,北京的奥运场馆存在一些好大喜功的地方要改。他还透露,上周六,北京市发改委向市领导汇报了场馆瘦身计划,不过,项目的定址工作还没有最后完成。  “奥运场馆的地点,我们原则上不主张改变。”杨兆科说,考虑到招标的严肃性和对国际社会的负责,此次瘦身计划主要是在原来的地点上进行微调,改变建筑结构、建筑规模和建筑结构的形式。  不过,杨兆科并没有完全否认部分场馆改址的可能性。  在3日结束的第八届京港经贸洽谈会上,香港方面向北京市委书记刘淇提出,希望2008年北京奥运会将马术比赛转到香港举行。  杨兆科解释说,马术这项比赛对场地要求非常严格,要求50公里以内不准有我们的马,这对北京来讲是个很大的压力。虽然目前就此事与香港方面在谈,但最后还得通过国际奥委会批准。                  奥运场馆详细进程将公开  杨兆科认为,奥运场馆调整之后,节省的费用将涉及几十亿元。不过,此次场馆调整方案充分听取了正反两方的意见,应该可以经得起时间考验。  至于究竟能省多少钱,杨兆科没有给出具体的数字。因为,目前向市领导汇报的结论也只是发改委、规委、财政局等部门与项目法人谈判形成的初步结论,具体的数字还有待于最后确定,因为合同变更,方案的修改等是需要付一些成本,因此,具体是节省40亿、50亿还是60亿,需经综合评判之后才能说。  杨兆科还透露,北京市发改委计划将在今年年底或者明年,通过北京市奥运工程建设指挥部将每一个奥运场馆的建设进程、以及每个阶段中期和后期招标的内容和额度进行公开,每个阶段需要采购什么东西,哪条路要建,有什么要求,都向社会公开,以解决信息不对称的问题。                  奥运经济不仅仅是2008年              北京奥运会经济研究会会长魏纪中支招北京企业  “如果在2008年北京奥运舞台上没有北京的演员,或者北京的企业只是在跑龙套,那将是北京企业的悲哀厂昨天上午,北京奥组委执委、北京奥运会经济研究会会长魏纪中一语惊人。  魏纪中是在参加2004年北京奥运经济论坛时作上述表示的。这位对体育经济深有研究的老人呼吁,北京的政府部门要培育和规范市场方面下功夫,北京的企业要在提高自身能力方面努力。                  北京企业缺乏奥运商业眼光  魏纪中认为,现在大家都在谈奥运会市场开发,其实市场开发首先在于开发市场和培育市场。本身就没有多少的市场,哪来的商机  刚刚从雅典回来的魏纪中感慨地说:“我在雅典见过浙江、山东、广东、福建的产品,惟独没有看到北京的产品。”  国外搞贴牌生产,很少找北京的企业,就拿体育用品和服装来讲,中国制造的占世界的70%,但没有北京企业生产的。这是值得北京的企业深思的。                  奥运经济不仅在2008年  魏纪中指出,要从时间和空间上来理解奥运经济的概念,只要历史上存在奥运会,就会有奥运经济,2008年之后,企业照样可以为其他国家举行奥运会提供商品和服务。  魏纪中提醒企业界人士,不要小看为外国产品做贴牌生意,虽然利润薄,但是这是企业进军国际市场的第一步。他举了一个例子,雅典奥运会部分场馆的座椅是由浙江余姚的一家企业生产的,意大利都灵冬奥会组委会人士在雅典参加奥运会时看上了这家企业生产的产品,指名要这家浙江企业为他们提供座椅。                  办奥运要替百姓解决问题  魏纪中颇有体会地说,雅典市政府的聪明之处在于他们并不急于建设奥运场馆,而是通过办奥运会,解决老百姓反映最强烈的、抱怨最多的问题。尽管场馆建设÷直拖到奥运会开始,但是最后还是完成了,也没有出现什么问题。  “抱怨雅典市政府的都是那些参加奥运会的人,他们算什么,他们才在雅典待20天。”魏纪中笑着说,关系老百姓的福利的东西搞好了,老百姓满意了才是最重要的。                             ――新京报

给定资料反映了北京奥运瘦身的计划,用不超过200字对这一事件进行概括。要求:全面,有条理,有层次。
