一年前在东京奥运会包揽女子100米领奖台的三名牙买加选手，在北京时间18日上午进行的田径世锦赛女子100米决赛中再度包揽前三，只不过名次有了变化：东京奥运会亚军、35岁的弗雷泽以10秒67创下新的世锦赛纪录，这也是她个人第5枚世锦赛100米金牌。她的队友杰克逊从东京奥运会季军升为亚军，东京奥运会三冠王汤普森收获铜牌。         (ECNS) -- Freight trains from Xi'an, Shaanxi Province, have shipped more than 34,000 air conditioners, fans and other cooling products to 15 European countries this year, meeting surging demand during a heatwave.     Rail shipments reach Europe in about 12 days, compared with 40 days by sea, according to Xi'an International Land Port officials.        The port has introduced smart terminals and fast-track services for cooling appliances.    The range of goods carried by China-Europe freight trains has expanded from basic building materials and household goods to high-end products such as new energy vehicles and lithium batteries, as well as consumer goods such as cooling appliances.    The trains have served as an important link for trade and economic exchanges across Eurasia, supporting the Belt and Road Initiative.    （By Helen Mo & intern Liu Shuangjing）                    。
