【正确答案】 World Expo 2010 was held in Shanghai from May 1 to Oct. 31. 190 countries and 56 international organizations participated in the Expo. More than 73 million tourists from home and abroad visited the Expo Park, reaching the largest number of attendance in all Expos. The theme of the Shanghai Expo is "Better City, Better Life", which reflects human's wish for a more livable environment and a better life. The China Pavilion was one of the most popular pavilions among all in the Expo Park.

【答案解析】1．第1句中既有时间状语，又有地点状语，一般地点在前、时间在后。“(活动)在……举行”可套用句型sth．was held in…，用被动语态。
2．第2句可逐字对译为the Expo had attracted．．．to attend the Expo，或可意译为190 countries…participated in…,省略“博览会吸引了”不译，不但没有影响原意的表达，还能使译文简洁明了。
3．第3句“超过7300万中外游客参观了世博园”中的“游客”可用visitors或tourists，由于“参观”用了visited，选用tourists来表达可避免重复。“参观人数是历届世博会中最多的一次”是对该句中“7300万”的补充说明，故将其处理成分词短语作状语，译作reaching the largest number of attendance in all Expos。
4．第4句中的“体现了……”是对前半句的补充说明，可用非限制性定语从句来表达，译作which reflects…,也可用分词短语reflecting．．．来表达。
